It is of interest to document the known relationship between periodontal status and Angle痴 malocclusion types. We used 26092 case records of patients between 16 to 50 years of age with no gender restrictions. Variables such as age, gender, periodontal diagnosis and type of Angle痴 occlusion were extracted and tabulated. Statistical analysis was completed using chi square test in the SPSS software version 20. Data shows that the majority (95.27%) had Angle痴 class I occlusion and less than 5% had class II and Class III occlusion. Statistical analysis of class II and Class III cases with 1000 randomly selected cases of class I occlusion show a significant difference in the periodontal status between different types of Angle痴 occlusion. Chronic periodontitis was more in class I (10.4%) and it was the lowest in Class II Div 2 (4.3%) occlusion. Class II Div 1(23.8%) and Class III (17%) had the highest and lowest proportion of clinically healthy periodontium, respectively. Thus, we report that angles occlusion types had significant influence on periodontal status along with the other determinants.

Edentulism is the state of being edentulous without natural teeth in the oral cavity. Edentulism leads to impairment of normal function, aesthetics, Comfort and speech which is followed by sequelae of undesirable events which includes occlusal discrepancies, migration and spacing of surrounding teeth, loss of space, supra eruption of teeth and temporomandibular disorders. The Variation in the number and location of the edentulous spaces and its complex relation to the remaining tooth structure or the natural teeth constrains the need to classify the partial edentulous arches. The aim of the current study was to assess the frequency of partial edentulism according to Kennedy's classification system. The retrospective study was conducted among the outpatient department of Saveetha Dental College and Hospital from June 2019- august 2019. The patient data was assessed. The data were tabulated using MS-Excel. The data was then analysed using IBM SPSS software (version 20). Pearson's chi-square test was done. Male predilection (62%) was identified in relation to partial edentulism. The most frequently observed edentulism in maxillary and mandibular arch was Kennedy's class III (23% and 21% respectively). While Kennedy class I and II were observed in patients aged between 50-80 years (11% and 14% respectively), whereas Kennedy's class IV was majorly observed among patients aged between 20-30 years (5%) (p<0.05). There was an increased frequency of Kennedy’s class I and II pattern and a decline in Kennedy’s class III and IV with increase in age.

Introduction: Teeth eruption is important for the development of alveolar process which increases vertical height of the face and third molar is the last tooth to erupt in the oral cavity after birth. The aim of this study was to determine relationship between skeletal malocclusion and dental anomalies in Nepalese population. Materials & Method: A sample of 170 patients with agenesis of at least one third molar was divided into four groups according to the third-molar agenesis pattern. Panoramic radiographs, lateral cephalograph and cast models were used to determine the skeletal malocclusion and associated dental anomalies. The Pearson chi-square test was used for stastical analysis. Result: Among 170 patients more than half of the patients were female with the average age being 18.15 ± 3.64 years. Majority of the patients had Class I skeletal malocclusion followed by Class II and III but on group wise comparison of patients with different skeletal patterns Class I skeletal malocclusion had highest prevalence of dental anomalies followed by Class III and Class II malocclusion. Conclusion: Prevalence of third-molar agenesis was more in skeletal class I malocclusion followed by class II and III but skeletal Class I malocclusions had more dental anomalies followed by class III and class II malocclusion.

SUMMARY The objective of this study was to evaluate the 24-month clinical performance of three different bulk-fill restorative resin materials in class II restorations. Forty patients with at least three approximal lesions in premolar and molar teeth participated in the study. A total of 120 class II cavities were restored using Tetric EvoCeram Bulk Fill (n=40), SureFil SDR flow + Ceram.X mono (n=40), and everX Posterior + G-aenial Posterior (n=40) with their respective adhesives according to the manufacturers' instructions. All restorations were placed by one operator. The restorations were evaluated at baseline and at six, 12, 18, and 24 months using modified US Public Health Service criteria by one examiner. The restoration groups for each category were compared using the Pearson chi-square test, while the Cochran Q-test was used to compare the changes across different time points within each restorative material (p&lt;0.05). At the end of 24 months, 94 restorations were evaluated in 33 patients, with a recall rate of 82.5%. There were no statistically significant differences between the groups in terms of retention (p&gt;0.05). At the 24-month recall, two restorations from the SureFil SDR flow + Ceram.X mono group and four from the everX Posterior + G-aenial Posterior group showed slight marginal discoloration and were rated as bravo. No marginal discoloration was observed in any of the Tetric EvoCeram Bulk Fill restorations. Six restorations from the Tetric EvoCeram Bulk Fill group, six from the SureFil SDR flow + Ceram.X mono group, and 12 from the everX Posterior + G-aenial Posterior group received bravo scores in terms of marginal adaptation. No difference was found among the three groups for any of the evaluation criteria tested (p&gt;0.05). There were statistically significant differences between the baseline and 24-month recall in the everX Posterior + G-aenial Posterior group in terms of marginal discoloration (p&lt;0.05). For marginal adaptation, a significant difference was observed between baseline and 24 months for all the restorative resins (p&lt;0.05). All the restorative resins tested performed similarly and showed acceptable clinical performance during the 24-month evaluation.

ABSTRACT Objective: The aim of this study was to evaluate the periodontal status of teeth indicated for undergoing endodontic treatment. Materials and Methods: Two hundred and nine teeth were evaluated using probing depth tests at three vestibular and three palatine/lingual sites before the patients underwent treatment. Teeth that presented up to 3-mm probing depth were considered as healthy. Those that presented at least one site with probing depth >3 mm were considered periodontally compromised. The data were statistically analyzed by means of applying the Chi-square test, with a level of significance of 5%. Results: Of the total of 209 teeth evaluated, 40 (19.10%) presented periodontal compromise. There was statistically significant difference related to the compromised teeth of patients of the female gender (22.80%) compared with teeth of patients of the male gender (12.30%) (P < 0.05). Conclusions: Fewer than 20% of the teeth evaluated presented a periodontal compromise. Patients of the female gender presented a higher number of periodontally compromised teeth than patients of the male gender.

Objective: To determine the number and pattern of palatal rugae in Nepalese subjects and to find the association of gender with the number and pattern of palatal rugae. Materials & Method: 200 Nepalese subjects comprising of 100 male and 100 female were randomly selected and their maxillary casts were examined for the palatal rugae length applying the classification proposed by Thomas and Kotze and palatal rugae pattern was recorded using the classification given by Kapali. Statistical analysis using Student t-test was applied for comparing the number of palatal rugae between right and left sides. Chi square test was used to find the association between gender and number of rugae as well as the pattern. Result: The study demonstrated that the mean number of primary palatal rugae on left side was predominant, similarly wavy pattern was the most predominant in Nepalese subjects. No statistical significant difference was noticed in the palatal rugae number and pattern between the gender groups. Conclusion: The study found predominant palatal form in Nepalese subjects which might have superior effectiveness in population differentiation and may be used as an effective tool in forensic odontology identification.

SUMMARY Objective: To compare the 24-month clinical performance of two different resin composites in class II slot restorations. Methods and Materials: Thirty-seven patients having at least two approximal carious lesions were enrolled in the study. A total of 116 teeth (58 pairs) were restored with either a silorane-based composite (Filtek Silorane) and its self-etch adhesive (Silorane Adhesive System, 3M ESPE) or a methacrylate-based packable resin composite (X-tra Fil) and its self-etch adhesive (Futurabond NR, VOCO GmbH) according to the toss of a coin. The restorations were evaluated at baseline and at six-, 12-, and 24-month recalls by two calibrated examiners according to the modified US Public Health Service criteria. The comparison of the two restorative materials for each category was performed with the Pearson chi-square test. Within group differences of the materials at different recall times were compared using the Cochran Q and Friedman tests. Bonferroni-adjusted McNemar test was used when significant difference was found (p&lt;0.05). Results: After 24 months, no statistically significant differences were found between the two restorative materials for the criteria evaluated. Conclusions: Both silorane- and methacrylate-based resin composites showed clinically acceptable performance in class II slot restorations after 24 months.

ABSTRACT Introduction: Pubertal growth peak is closely associated with a rapid increase in mandibular length and offers a wide range of therapeutic modifiability. Objective: The aim of the present study was to determine and compare the mean ages of onset and duration of pubertal growth peak among three skeletal classes. Methods: A retrospective cross-sectional study was conducted using lateral cephalograms of 230 subjects with growth potential (110 males, 120 females). Subjects were categorized into three classes (Class I = 81, Class II = 82, Class III = 67), according to the sagittal relationship established between the maxilla and the mandible. The cervical vertebral maturation stage was recorded by means of Baccetti's method. The mean ages at CS3 and CS4 and the CS3-CS4 age interval were compared between boys and girls and among three skeletal classes. Results: Pubertal growth peak occurred on average four months earlier in girls than boys (p = 0.050). The average duration of pubertal growth peak was 11 months in Class I, seven months in Class II and 17 months in Class III subjects. Interclass differences were highly significant (Cohen's d > 0.08). However, no significant difference was found in the timing of pubertal growth peak onset among three skeletal classes (p = 0.126 in boys, p = 0.262 in girls). Conclusions: Girls enter pubertal growth peak on average four months earlier than boys. Moreover, the duration of pubertal growth peak is on average four months shorter in Class II and six months longer in Class III subjects as compared to Class I subjects.
