OBJECTIVES: To objectively determine the correlation of lower third molar angulation and posterior space discrepancy with mandibular anterior crowding digitally using intraoral scanner. METHODOLOGY: Cross sectional analytical study conducted at Rehman College of Dentistry (RCD) Peshawar from15th November 2020 till 15th December 2020. Lower third molar angulation and posterior space discrepancy were measured by IC 3.1 measure software, using digital Orthopantomograms (OPG). Digitally scanned models by (CS 3600 intraoral scanner) were analyzed using (CS 3600 3D software).  Sample was divided into Control (N=30; perfect alignment), Experimental (N=30; crowding >1mm) groups, based on Little’s Irregularity Index. Both lower third molar angulation and posterior space discrepancy (Ganss Ratio) were correlated with lower anterior crowding using Pearson’s Correlation. To determine any difference between two groups independent t-test was used. RESULTS: Statistically insignificant difference and a weak correlation were found for Ganss ratio and third molar angulation in both control and experimental groups. CONCLUSION: Third molar angulation and the retro molar space has no direct effect on the lower anterior crowding.

Introduction: Crowding in mandibular arch increases with increasing age and etiology of crowding is multifactorial in nature. Role of mandibular third molar in lower anterior crowding remains a topic of controvery over a period of century. The objective of this study was to assess whether there is any correlation between presence of mandibular third molar position and lower anterior crowding. Materials and Method: On the basis of third molar position one hundred and six sample of pretreatment orthodontic patients aged between 17 to 38 years were divided into erupted, erupting and agenesis group. The study was conducted in Peoples Dental College and Hospital from January 2020 to March 2020 after obtaining ethical approval from the institutional review committee. This cross-sectional study was done on dental casts and orthopantomogram; brass wire was used for measuring arch length and digital vernier caliper for measuring tooth material with modified segmental arch analysis method. Result: Among 106 samples collected 55 (51.88%) were female and 51(48.11%) were male and the mean age was 21.53 ± 3.91 years, Chi square and ANOVA test was used for Statistical analysis. This study showed no statistically significant differences between third molar position and lower anterior crowding on right (P= 0.68) and left side (P = 0.45). The study also showed that association between the third molar position and lower anterior crowding is more on left side compared to right side. Conclusion: Mandibular third molars have not statistically significant difference in lower anterior crowding so, extraction of third molars for relieving the anterior crowding is not justifiable

Abstract Background: The role and involvement of mandibular third molars on mandibular incisor crowding, post retention, in orthodontically treated patients has long been debated. The correlations between lower anterior crowding and lower third molar angulation and space are not completely understood. Aim: To assess the lower third molar space and its angulation in individuals with lower anterior crowding and to compare it with that of individuals without lower anterior crowding. Settings and design: Hospital based Prospective, cross-sectional study on randomly selected individuals. Materials and Methods: Lower third molar space and angulations were measured and compared using orthopantomograph tracings of 80 subjects in the age group of 20-30 years with skeletal Class I malocclusion individuals without lower anterior crowding(Group A) and individuals with lower anterior crowding (Group B). Statistical Analysis: Both the space and angulations of lower third molar were correlated with the lower anterior crowding using Pearson Correlation Coefficient. Results: Significant differences were found in third molar space between the study group and the control group. But there was no significant difference in third molar angulation between the groups. Conclusion: the lower anterior crowding has a significant influence on third molar space but did not have any effect on third molar angulation.

Objectives: The aim of this study was to assess the role of impacted third molar angulation on the severity of anterior crowding. Materials and Methods: Panoramic radiographs and three-dimensional (3D) digital models of 45 patients satisfying the following inclusion criteria were selected for this study. To calculate the irregularity index of Little, the sum of the contact point displacements from the anatomical contact point to the contact point among the lower canine teeth was measured on 3D digital models. Little’s irregularity index was used to classify patients as having mild, moderate, or severe crowding. For intragroup variance, comparisons T test was used. The Spearman single rank correlation coefficients were used to analyze any correlation among degree of crowding and (a) third molar inclination to base of mandible, (b) third molar inclination to occlusal plane, and (c) third molar inclination to second molar inclination respectively. Results: There were no statistical differences found in all tested parameters (i.e., third molar inclination to mandibular plane, inclination of the third molars to occlusal plane, and inclination of the third molars to second molars) among three groups (P > 0.005). Conclusion: It can be deduced that no relationship obtains among the third molar inclination to base of mandible, third molar inclination to occlusal plane, third molar inclination to second molar inclination, and the level of anterior crowding.

Abstrak. Penentuan tinggi badan memiliki peran penting dalam menentukan identitas personal pada kasus  penemuan jenazah yang tubuhnya sudah tidak utuh lagi. Perkiraan tinggi badan pada jenazah yang tidak utuh dapat diketahui dengan mengukur panjang bagian tubuh tertentu dari jenazah tersebut, salah satunya adalah panjang tulang sternum. Tujuan penelitian ini adalah untuk mengetahui korelasi dan menentukan rumus perkiraan tinggi badan berdasarkan jenis kelamin menggunakan panjang tulang sternum. Penelitian ini merupakan penelitian analitik dengan pendekatan cross sectional. Untuk mengetahui korelasi dan menentukan rumus regresi linier dilakukan uji statistik dengan menggunakan software IBM SPSS 26.0. Pada penelitian ini dilakukan pengukuran tinggi badan dan panjang tulang sternum pada 230 responden (115 pria dan 115 wanita) yang berusia 18-45 tahun di Provinsi Riau. Didapatkan korelasi bermakna antara panjang tulang sternum dengan tinggi badan (p0,01) pada responden pria dan wanita. Nilai koefisien korelasi pada responden pria (r = 0,33) dan wanita (r = 0,24) menunjukkan kekuatan korelasi lemah. Rumus regresi tinggi badan pada pria didapatkan yaitu: TB = 144,35 + 1,13(PS) ± 6,44 cm dan pada wanita: TB = 139,20 + 0,96(PS) ± 4,87 cm. Hasil penelitian ini menunjukkan bahwa panjang tulang sternum memiliki nilai forensik terbatas dan keandalan yang relatif rendah dalam memperkirakan tinggi badan manusia.Kata Kunci: Identifikasi, sternum, tinggi badan, korelasi, formula regresiAbstract. The determination of body height possesses a great and important role in establishing personal identities when founding an incomplete human corpse. The estimation of body height can be determined by measuring certain parts of the body, one of which is the length of the sternal bone. The purpose of this study was to understand the correlation and determining the approximate height equation based on sex using the sternal length. An analytical study with a cross-sectional approach was used in this research. To perceiving the correlation and determining the linear regression formula, a statistical test was performed using IBM SPSS 26.0. In this study, height measurement and the sternal length were recorded from 230 respondents (115 males and 115 females), aged between 18-45 years old in Riau Province. A significant correlation was obtained between sternal length and body height (p 0,01) in male and female respondents. The correlation coefficient (r) score for male (r = 0,33) and female (r = 0,24) respondents indicates a weak correlation strength. Height regression formula in men is obtained, namely: Body Height = 144,35 + 1,13(Sternal Length) ± 6,44 cm and in women: Body Height = 139,20 + 0,96(Sternal length) ± 4,87 cm. The result of this study shows that the length of the sternum bone has limited forensic value and relatively low reliability in estimating human height.Keywords: Identification, sternum, height, correlation, regression formula

Aim and Objective: To assess the level of awareness among local adult population (orthodontically untreated) regarding orthodontic treatment and procedures. Materials and Methods: A cross-sectional study was planned by accessing 100 subjects comprising of 2 groups (50 male and 50 female). After due ethical clearance, a self-structured questionnaire consisting of 17 questions was given to a group of randomly selected 100 individuals with an age range of 20 to 30 years. Results: The overall awareness of orthodontics as a speciality among both the groups was only 52% to 56%. Statistically insignificant difference was found in the knowledge and awareness of orthodontic treatment among both male and female subjects, that is, Group I and II. Also, those who knew about the orthodontic treatment did not opt for it because of high cost and longer duration involved. Conclusion: More than half of the population is unaware of the scope of orthodontic treatment, and thus, they do not seek any assistance. Hence, more efforts are needed to create awareness about orthodontics and the associated benefits.

The Relationship

The aim of the present study was to evaluate the relationship between BMI and tooth decay in a population of Iranian children. In this cross-sectional descriptive/analytical study, 1482 children were selected from kindergartens and preschool centers in Kerman, Iran. The children underwent examination of deciduous teeth (using the dmft index) after determination of height and weight for calculation of BMI. The relationship between BMI (after adjustment for age) and dmft was determined using Poisson’s regression model. The mean of dmft in children with normal BMI was 1.5-fold that in subjects with extra body weight. Age had a significant effect on dmft. In addition, dmft was higher in boys compared to girls. The results of the present study showed that caries rate in the deciduous teeth of 3–6-year-old children decreases with an increase in body weight.
