instrumentation
primary tooth
root canal therapy
Introduction: Although rotary instrumentation has been widely studied in permanent dentition, it is a rather new field of study concerning primary teeth. Purpose: We aimed to evaluate apical displacement and time needed for instrumentation of root canals of primary molars by manual and rotary techniques. Materials and Methods: Root canals of 144 extracted first and second primary maxillary molars were randomly divided into 2 groups: I- manual instrumentation (K-files); II- rotary instrumentation (K3 Rotary System®). The canals were radiographed with pathfinding files in place, prepared by both techniques, and instrumentation time was recorded. After preparation, root canals were radiographed again with pathfinding files in place. To analyze the degree of apical displacement, digital images were superimposed using the Adobe Photoshop® software. Results: Mean apical displacement (0.70 mm) in the manual instrumentation group was not statistically different from that in the rotary instrumentation group (0.79 mm). However, mean time for root canal preparation was significantly shorter using the rotary system (128.0 s) than using the manual system (174.0 s) (p<0.05). Conclusions: The use of rotary instrumentation in pediatric dentistry is feasible, offering time-saving advantages in root canal preparation.

Purpose: The present study aims to evaluate, ex vivo, the accuracy of electronic apex locators Root ZX II and Romiapex-15, for working length (WL) determination in permanent teeth. Materials and Methods: Fourteen single-rooted teeth (incisors and canines), with their apices fully formed were used. The dental crowns were removed. The anatomic length of the tooth (real measurement) was visually determined through the insertion of a size 10 K-file until the tip of the instrument could be observed in the apical foramen under a microscope (20X). Teeth were fixed in a model of resin and adapted into alginate soaked with saline solution, which was used as an electrical conductor. Using a K-file, root canals were measured electronically using both devices. The results obtained for each apex locator were compared to the real measurements. The accuracy between the devices was statistically analyzed using the Bland-Altman graph, Intraclass Correlation Coefficient (ICC), and Student’s t-test. Results: The mean difference between the measurements using the Root ZX II was 0.277mm greater than the real measurement, while the measurements from the Romiapex-15 were 0.308mm higher on average. The comparison between Root ZX II and Romiapex-15 had no significant difference (p= 0.868). Conclusion: It was concluded that Root ZX II and Romiapex-15 had similar accuracy. Romiapex-15 could be an option for WL determination in permanent teeth.

The aim of this study was to evaluate in vitro the amount and profile of fluoride release from a fluoride-containing nanohybrid composite resin (Tetric® N-Ceram) by direct potentiometry. Thirty specimens (5 mm diameter x 3 mm high; n=10/material) were made of Tetric® N-Ceram, Vitremer® resin-modified glass ionomer cement (RMGIC) (positive control) or Filtek® Z350 nanofill composite resin (negative control). The specimens were stored individually in plastic tubes containing 1 mL of artificial saliva at 37°C, which was daily renewed during 15 days. At each renewal of saliva, the amount of fluoride ions released in the solution was measured using a fluoride ion-selective electrode with ion analyzer, and the values obtained in mV were converted to ppm (µg/mL). Data were analyzed statistically by ANOVA and Tukey’s post-hoc test at a significance level of 5%. The results showed that the resins Tetric® N-Ceram and Filtek® Z350 did not release significant amounts of fluoride during the whole period of evaluation (p>0.05). Only Vitremer® released significant amounts of fluoride ions during the 15 days of the experiment, with greater release in first 2 days (p<0.05) and stabilization in the subsequent days (p>0.05). In conclusion, the nanohybrid composite resin Tetric® N-Ceram did not present in vitro fluoride-releasing capacity throughout the 15 days of study.

Familial aggregation of mandibular prognathism
Lee, April
Yang, Chris
class III malocclusion
orthognathic surgery
eastern Asian
Mandibular prognathism is a hereditary condition where there is an excess growth of the mandible in relation to the maxilla that can be associated with maxillary retrusion, mandibular protrusion, or both. Skeletal mandibular prognathism is most prevalent in Eastern Asian populations. This paper focuses on a Korean family with skeletal mandibular prognathism that was inherited through three generations. Apparently, neither mandible nor maxilla is retruded in the affected individuals, but there is a concave facial profile. The dentition has a class I occlusion with skeletal mandibular prognathism, and the only way to treat this case would be orthognathic surgery with the help of orthodontic appliances.

Agenesis of all third molars in two half siblings
Kaufer, Jamie A
PAX9
tooth agenesis
Tooth agenesis is one of the most common dental anomalies and is influenced by factors including patient genetics. Although there are several specific genes associated with certain patterns of agenesis, there does not seem to be a genetic pattern identified to date that is associated with isolated complete third molar agenesis. This report presents two half-siblings who both express complete agenesis of third molars despite the fact that their shared parent does not express the same phenotype. The case discussion focuses on addressing the potential genetic possibilities including autosomal dominant inheritance and variable expressivity of a mutation. There remains an uncertainty to the exact gene involved. Potential options include WNT10A and PAX9. The affected individuals are not needing extractions or experiencing complications due to the presence of third molars. However, the concern remains that there is the potential for more severe expression of the mutation in future generations.

Haitian orphan population and protective factors against caries
Rea, Madelyn
Dental Caries
Enamel Discoloration
Dental Trauma
Objective In Haiti, families were torn apart and children were left orphans after the 2010 earthquake. In the aftermath of this natural disaster many children were relocated to orphanages across the country and adopted internationally. Years later these children find themselves catching up in growth physically, mentally and emotionally after an extremely traumatic event during a crucial time in their health development. Another important marker of development is the primary dentition and the presence of caries. We report estimates of early childhood caries (ECC) frequency, risk factors and quality of health among Haitian children. Methods Medical and dental professionals conducted a descriptive cross sectional study through the Pittsburgh Kids Foundation and their partnership with IDADEE children’s home, EBAC orphanage and New Vision Children’s home. Vital signs were taken and recorded to create a health/growth history for each child. Brief dental screenings were conducted and topical fluoride treatments were administered. Risk factors and quality of health information was obtained from discussions with the caregivers present. The children and caregivers were given oral hygiene education and supplies (i.e. toothbrushes, toothpaste, floss). Results Physical exams and dental screenings were conducted on the 40 children ages 3-10 years of age living in the IDADEE children’s home. Two children had cavitated teeth. Eight children had teeth that were stained. Four children had evidence of dental trauma. 26 out of the 40 children had otherwise healthy dentition. Conclusion The IDADEE children’s home and New Vision Children’s home have hopes to expand their capacity with new construction scheduled to be finished in 2016. As more children enter these homes action is needed to educate caregivers on ways to identify high-risk children to prevent ECC and ways they can be treated before irreversible damage is done to the developing permanent dentition.

Third Molar Eruption Mechanisms and Patterns
Zhang, Winnie
Third molars
etiology
impacted
abnormality
hereditary
Third molars are highly variable in their presence and form. This report focuses on a horizontally impacted third molar and analyzes the potential etiology of this situation. Upon a clinical and radiographic examination, it was noted that the patient had four third molars present. The patient’s third molars began erupting around the age of 19. Currently, they are asymptomatic with incipient caries on the occlusal surfaces. While three of the third molars erupted in a normal orientation, one of the third molars (mandibular left) erupted in an orientation that would be classified as horizontal and/or mesio-angular. No treatment has been undertaken at the moment, however surgical extraction can be recommended with the prognosis being very good. For the clinician that has to treat dental complications that arise from abnormal tooth eruption, as seen in numerous genetic and acquired disorders, knowledge about the basic molecular mechanisms involved may become extremely important.

Lactobacillus mutans removal
Background. Polymer bur is a new technology that proposes to conserve the dentin that is capable of remineralization. Aim: To conduct a quantitative systematic review to evaluate the effect of polymer burs on the reduction of Streptococcus mutans and Lactobacillus after dentin carious excavation in deciduous teeth. Methods and Material: Two reviewers performed the database to identify the relevant clinical papers. Only papers in English that compared polymer burs with other caries removal techniques with the microbiological aspects as an outcome were included. Papers that evaluated only permanent teeth were excluded. Risk of bias was also assessed. Individual study effect sizes were calculated using Cohen’s d formula for the comparisons of microorganism reduction before and after carious excavation. Results: The search resulted in 12 non-duplicated papers. After the revision, only 2 were selected. The quantitative evaluation demonstrated that polymer bur reduces microorganism levels in carious dentin. The larger effect size observed was for Streptococcus mutans in the polymer bur technique (r=0.84; d=3.12), followed by Lactobacillus in the carbide bur technique (r=0.83; d=3.03). Conclusion: Polymer burs promoted a significant reduction of microorganism levels, mainly Streptococcus mutans in carious dentin.

Behavioral genetics and thumb sucking in adolescents
Hatala, Jessica
Nonnutritive sucking
thumb sucking
behavioral genetics
malocclusion
Thumb sucking is a common habit developed by children and begins as early as in utero. However, it becomes problematic when a child continues to suck their thumb past the age of 4 years, when their secondary dentition is developing and preparing to erupt. Prolonged thumb sucking into adolescence can have deleterious effects on dental and skeletal structures based on the duration and how frequent the child engages in this nonnutritive sucking habit. Thumb sucking can lead to various types of effects such as increased overjet, anterior open bite, posterior cross bite, maxillary arch constriction, high palatal vault, and Class II malocclusion. This paper presents a case study, which focuses on chronic thumb sucking in a family, the dental and skeletal changes that the family members experienced, and whether or not this prolonged behavior can be genetically influenced. Based on this case study and the field of behavioral genetics it is possible that there can be a genetic component to the duration of thumb sucking into adolescence.

Aim: Although there are many materials that can be used for retrograde filling in surgical endodontics, none of them can be regarded as an ideal material yet. The purpose of this study was to compare the surface topography of three different root-end filling materials.Methods: 36 extracted single rooted human incisor teeth were cleaned and decoronated to standardized 10 mm root lengths. The root segments were prepared and 2 mm apical resection were performed. The samples were randomly separeted to three groups (Group A: Ca(OH)2, Group B: MTA Angelus, Group C: ProRoot MTA), each comprised of 12 roots. Materials were placed as 2 mm apical barriers and obturated with guttapercha and AH-Plus sealer. Each group dimidiated two subgroups (A1,A2,B1,B2,C1,C2). Groups A1,B1,C1 were stored in normal saline (NS), groups A2,B2,C2 were stored in neutral phosphate buffer saline (NPBS) solution and samples were incubated at 370C for 2 weeks. Stereomicroscope (32X) was used to photograph the root-end filling.Results: All specimens demonstrated white crystals formation and sediment over the root-end filling materials and on the superficial border of the root-end cavities’ wall as a white plague. A2,B2,C2 samples have more crystal sediment on root-end fillings than samples A1,B1,C1. Dissolution and corrosion were observed in groups A1, A2.Conclusions: The results of this study revealed that calcium hydroxide is more resorbable than MTA Angelus and ProRoot MTA. The crystals formation and precipitation were observed in neutral phosphate buffer saline solution was more than normal saline solution for all groups as a hydroxiapatite crystals.

Abstract The aim of this study was investigate`s patient and parent’s aesthetic perception and psychological impact of molar-incisor hypomineralisation (MIH) and to assess the correlation of MIH with caries experience. The sample comprised 56 children, 28 with MIH and 28 without MIH (comparison group), and their gardens (n=56). For the perception data we used the Child and Parent’s Questionnaire of Teeth Appearance. We used the European Academic of Paediatric Dentistry (EAPD) criteria to define MIH. Caries experience was assessed by Decayed, Missing and Filled Teeth (DMFT) index. Chi-square, Student’s t-test and correlation tests were used with significance level set at 5%. Most children were male (n=35; 62.5%) and patients with MIH perceived their affected teeth as stainned (p=0.01). MIH was considered by parents (6.96±1.7) to enhance psychosocial condition (social, physical, and psychological social) of their children (p<0.01). Patients with severe MIH showed the worst perception about the color of the teeth (p=0.07). There was no correlation between DMFT scores and presence of MIH (p=0.80). Patients and parents perceived MIH. Groups with severe MIH (children/ parents) showed the worse aesthetic perception.

Objective: Dental fear is a common phenomenon in children and parents can have a key role in the development of child's dental anxiety. There is moderate evidence to support the relationship between the parental general health and children’s dental fear. The aim of this study was to investigate the relationship between dental fear and cooperation of children during dental treatment with the general health of parents.Methods: This cross-sectional descriptive study was done on 130 children aged 6 to 12 at the Department of Pediatric Dentistry, Guilan University of Medical Sciences from May to September 2020.The personality traits and general health of parents were assessed by using the General Health Questionnaire (GHQ-28). The Frankl's behavior rating scale and Children's Fear Survey Schedule Dental Subscale (CFSS-DS) were used to respectively assess the degree of cooperation during dental practices and children’s dental fear. Statistical approaches included T-test, Chi-square and Pearson Linear correlation. A significant level of differences was taken as P<0.05.Results: 69.3 % of children behaved positively and definitely positively during dental treatment. 56 boys and 74 girls with mean age of 9.13 ±2.02 years participated in this study. There was a significant correlation between the children's age with dental fear and cooperation level (P<0.001). There was no significant difference in dental fear score (P=0.63) and cooperation level (P=0.99) between boys and girls. There was not statistically significant relationship between the general health of the parents and the level of children's cooperation and dental fear during dental treatment (P>0.001).Conclusion: There was not relationship between parent's general health with children's dental fear and cooperation.

Objective: The aim of this study was to compare the clinical and radiographic success rates of pulpotomy in primary molars using formocresol versus sodium hypochlorite.Methods: Twenty-three children aged 4-9 years with at least two primary molars requiring pulpotomy were randomly allocated into two groups. All teeth received stainless steel crown after conventional pulpotomy procedure with either NaOCl or formocresol. Clinical and radiographic signs/symptoms were recorded at six and 12 months. Outcomes were statistically analyzed using Fisher’s exact test and Chi-squaretest.Results: Clinical success rates at 6 and 12-month follow-up in both groups was 100%. At 6-month follow-up, radiographic success rate for NaOCl and formocresol groups was 100%. At 12-month recalls, in NaOCl group, 20 teeth (87%) and in formocresol group, 21 teeth (91.3%) had radiographic success. No significant difference was found in the radiographic success rates at 12 months (P=1.00). Internal root resorption was the most common radiographic pathologic finding in both groups.Conclusion:Clinical and radiographic success rates in NaOCl group was comparable with formocresol group, so NaOCL can be suggested as an alternative for primary teeth pulpotomies. However further clinical studies with long-term follow-ups are needed.

dental caries
Objectives: Calculate the prevalence and severity of dental caries and periodontal health among school students aged 12-18 years old and their attitudes toward dental health and oral hygiene at Al-Mafraq governate- Jordan.Materials and methods: Demographic and oral behavioral information were collected; students aged 12-18 years old from six public schools distributed over three districts in Al-Mafraq governate over a six-month period had a full oral and dental examination. DMFT index (Decay, Missing, Filling, Teeth) was used to measure caries experience. Plaque index (PI) and gingival index (GI) of Löe and Silness were used to evaluate the oral health status. T - test was used for statistical evaluation. A P-value < 0.05 was considered statistically significant.Results: 1165 students were examined, 51% never had been to a dentist or had any previous dental treatment, 39.6% of the students examined never brushed their teeth and 61.85 % had dental caries. The (SiC) was 4.72 with a decay representing 93.53%. Females brush their teeth more frequent than males with a statistically significant difference; p< 0.001. Females showed lower DMFT index (1.81) and compared to males (2.25) with a statistically significant difference. Females showed lower SiC (4.164) compared to males (5.186) with a statistically significant difference. There was no statistically significant difference between males and females in PI p= 0.590, and GI; p= 0.852.Conclusions: The prevalence of dental caries among students in Al-Mafraq governate and the significant caries index were substantially higher than the target goals of WHO/ FDA of year 2015 with more than 90 % of unmet treatment needs. Girls showed better oral hygiene habits compared to boys and exhibited less dental caries experience. However, periodontal status did not differ significantly between both genders.

Objectives: To define the prevalence of dehiscence and fenestration and classify them in terms of the localization of fenestrations in a random sampled group of children and adolescent patients using cone-beam computed tomography (CBCT).Methods: CBCT performed at the Department of Oral and Maxillofacial Radiology of patients referred by the paediatric dentistry clinic were included in this retrospective study. Image evaluations were performed by dentomaxillofacial radiologist (AA, asst. prof.), and these images were examined in three dimensions of the axial, coronal, and sagittal planes. Intraexaminer agreement for the evaluations were found acceptable. The presence/absence of dehiscence and/or fenestration, fenestration’s classification type, and localization of defects were recorded. Moreover, the presence/absence of periapical lesion in related root with dehiscence and fenestration was noted. For statistical analysis, The Chi-Square test, Fisher Freeman Halton Test, and Yates' Continuity of Correction were used.Results: 3061 roots in 1801 teeth of 120 cases were analyzed. The mean age was 9.97±2.22 years. Dehiscence was detected in 261(8.5%) roots of 161(8.9%) teeth, and fenestration was detected 63(2%) roots of 36(2%) teeth. The most common fenestration type was Type I, followed by Type II and IV. Dehiscence was observed more frequently in primary teeth than permanent teeth, and the difference was statistically significant (p:0.000). Dehiscence and fenestration incidence in maxillary teeth was significantly higher than in the mandibular teeth (pdehiscence:0.000, pfenestration:0.004). Apical lesions were observed more in primary teeth than permanent teeth for both defects.Conclusions: This study concludes that alveolar dehiscence and fenestrations are more common in primary teeth than permanent teeth. Moreover, these defects were detected more for the teeth in the maxilla. Concerning endodontic and orthodontic therapies in maxilla, use of CBCT is useful in determining the region's anatomical structure accurately in suspected cases of child and adolescent patients.

Purpose: To investigate the effect of chemomechanical caries removing agents (CCRAs) based on papain (Papacárie Duo Gel® and Brix3000®) over dentin surfaces compared with 37% phosphoric acid and 11.5% polyacrylic acid.Materials and methods: Sound human molars were sectioned at the crown level, resulting in 48 dentin blocks, which were randomly divided into 4 groups (n=12): 1) Papacárie Duo Gel®; 2) Brix3000®; 3) 11.5% polyacrylic acid solution and 4) 37% phosphoric acid gel. All products were applied for 30s. Ten blocks per group were analyzed by a non-contact 3D profilometer before and after treatments for linear (Ra) and volumetric roughness (Sa). The superficial morphology of the remaining blocks in each group (n=2) was evaluated by scanning electron microscopy (SEM). Normality was rejected for the data (Shapiro-Wilk test) and therefore, Kruskal-Wallis test, followed by Dunn’s proof or Wilcoxon signed rank test with its respective effect size calculation were used to compare the results with α=5%.Results: Ra and Sa values for specimens submitted to Papacárie Duo Gel® and Brix3000® were statistically similar to baseline values. Application of phosphoric and polyacrylic acid resulted in a statistically increase in roughness compared to the CCRAs. SEM evaluation showed that Papacárie Duo Gel® resulted in surface debris. Polyacrylic acid and Brix3000®resulted in partial opening of the tubules but dentin exposed to polyacrylic was able to remove more smear layer than Brix3000®, while phosphoric acid resulted in total opening of the dentinal tubules.Conclusion: Both Papacárie Duo Gel® and Brix3000® did not result in roughness changes when applied in sound dentin.

Verma, Aditi
Mehta, Abhishek
Background: The coronavirus disease (COVID-19) is profoundly affecting life around the globe. Social Isolation, contact restrictions and economic shutdown impose a complete change to the psychosocial environment threatening the mental health of young adults significantly.Objectives: The present study aims to assess the impact of Social Isolation on the mental health of young adults during the pandemic.Methods: A web based research was conducted on a sample of 438 college students of age 18-24 years. The participants were asked for responding to a standardized online questionnaire that included questions related to their anxiety levels and the 7-item Generalized Anxiety Disorder Scale (GAD-7).Results: The results revealed 78.4% of the study populations were suffering with mild (35.2%), moderate (23.7%), and severe anxiety (19.4%) respectively. Univariate and Logistic Regression Analysis revealed gender and course/year of study had a significant effect on the level of anxiety (p<0.05). Also, students living alone and having a relative or an acquaintance infected with COVID-19 were likely to be more anxious (p < 0.05). Spearman correlation analysis depicted Social Isolation as the main Covid-19 related stressor which was positively correlated and highly significant (p=0.0001) to the level of anxiety of young adults.Conclusions: The present study revealed approximately 43% of young adults is suffering from moderate to severe anxiety levels which require urgent attention.

Introduction: Mothers are commonly the first ones who encounter the dental avulsion in children. High knowledge of them could greatly affect the success rate of treatment. The purpose of this study was to evaluate the effect of educational poster on the mother’s knowledge about management of dental avulsion.Materials and Methods: This study was conducted at the Department of Pediatric Dentistry, Guilan University of Medical Sciences from November 2020 to February 2021. After obtaining the informed consent, a questionnaire containing the mothers’ socio-demographic information and 8 questions regarding knowledge about dental avulsion was responded alone by 262 mothers (131 in the study group and 131 in control group) before educational poster presentation in the study group. After three months, the participants of both groups were re-evaluated using the same questionnaire. McNemar’s test and Generalized Estimating Equations (GEE) was used to analyze the data. Results with P < 0.05 were considered statistically significant. Results: Use of an educational poster improved the knowledge of participants of study group about dental avulsion, although this improvement was statistically significant in questions regarding immediate emergency action (P=0.003), appropriate time for replantation (P<0.001), cleaning before replantation of a dirty tooth(P=0.022) and suitable storage medium for transferring an avulsed tooth (P<0.001). It was found that variables like age, level of education, employment status and previous training had no significant effect on participants knowledge(P>0.05).Conclusion: Results showed that the use of posters as an educational method can effectively improve mothers’ knowledge about management of children’s dental avulsion.

BACKGROUND: Dental caries is a world-wide public health issue and is considered the most common of all non-communicable disease. There has been a growing interest in association between oral fungal flora especially candida and dental caries. Hence the aim of the study was to assess the correlation between active caries status and oral candida carriage in children aged twelve years.MATERIALS AND METHODS: This is a cross-sectional study where a multiphase sampling was done and a total of thirty children were selected randomly among children screened previously. Data was collected through clinical oral examinations and structured interviews. The oral rinse technique described by Samaranayake et al. was used for extracting candida spp. The correlation between candida spplevel and caries experience was performed by the Pearsons correlation coefficient.RESULTS: The mean DMFS and defs scores of the children were 3.70±4.61 and 5.83±5.51 respectively. Significant association with decay scores for deciduous teeth (P<0.05) and defs (p= <0.001) was demonstrated. Candida species was associated highly with caries prevalence and significant positive correlation was found between Candida (CFU/plate) and defs scores (r=0.790) (p= <0.001)CONCLUSION: The study results suggested that there is a significant positive correlation between candida carriage and caries, especially in children in the age group of 12 years.

Monitoring of the Inverted Relation of Gingival Pads in a Non-Syndromic Infant
Chedid, Silvia José
Gingival rounding
Prognathism
Child
Infant
Angle Class III
BACKGROUND: Monitoring the occlusal relationship of the infant’s gum pads is not a common practice in pediatric dentistry. In general, pediatric dentists are used to observe the conformation of the arches and clinical findings that may be outside of the infant’s normal oral anatomy. Here we tested the hypothesis that intervention before eruption of the primary dentition will minimize anterior crossbite in the primary dentition. To address our hypothesis, we used one case to demonstrate the importance of monitoring the relationship of the gum pads and primary teeth eruption to avoid possible deviations in the pattern of orofacial development and prevent future malocclusions.MATERIALS AND METHODS: After proper consenting and anamnesis, an inverted relationship of the gum pads was observed in a 7-month-old baby while sleeping and at occlusal rest. Given that the patient was exclusively breastfeeding, adjustments of the catch were made, such as a greater opening towards the areola and nipple, and adjustments in the position and posture of the baby.RESULTS: During the eruption phase of the anterior teeth, an anterior crossbite was observed. Caregivers were prescribed exercises that were to be performed in the maxillary and mandibular arches to stimulate maxillary growth and guide the posture of the mandible. The exercises were intensified during the eruption phase of the lateral incisors and molars and the occlusion was stabilized with bilateral masticatory guidance and different textures to be offered during food transition. CONCLUSION: Based on the results observed for this case, the interventions allowed for a more satisfactory occlusion.
