The incidence of traumatic dental injuries (TDI) occurring in childhood has increased in recent years. According to the literature, this will soon exceed the incidence of tooth decay and periodontal diseases. 1 According to epidemiological studies, trauma to the oral region occurs frequently. Oral injuries account for 5% of all body trauma for all ages, and this rate is 18% in preschool children. 2,3 Traumatic dental injuries specifically are observed in 85% of patients with oral trauma. 4 Traumatic dental injuries are a social problem, as they are frequently encountered in ages of rapid development and have a high recurrence rate compared to other types of trauma. Furthermore, they often require long-term multidisciplinary treatments. 5-9 Several studies have analyzed the relationships between various underlying reasons for TDIs and their etiologies. However, very few

Objective: To investigate the differences in the academic productivity of male and female academicians from the departments of pediatric dentistry in the Faculties of Dentistry in Turkey. Methods: A search was made of international studies indexed in PubMed published up until January 2021 by a total of 241 academicians in the Departments of Pediatric Dentistry of 79 Faculties of Dentistry in Turkey. The total number of international publications for each faculty member was obtained from the institutional websites and thorough searches of PubMed and Web of Science. H-index and the number of citations were established through an advanced search of the Web of Science. Results: The study included 241 faculty members, consisting of 62 (25.7%) males and 179 (74.3%) females, from 79 faculties of dentistry. Male academicians had a statistically significantly larger number of citations from their publications indexed in PubMed than their female counterparts (p = 0.003). An examination of the h-index values from the Web of Science database revealed that male faculty members had significantly higher h-indices than female faculty members (p = 0.005). Conclusions: Although a majority of academicians in pediatric dentistry are female, large differences exist between female and male faculty members in citations and h-indices.

Objective This study aimed to establish the prevalence and patterns of nonsyndromic tooth agenesis in patients referred to a tertiary health care facility. Methods The intraoral records and panoramic radiographs of 9,874 patients aged 12–22 years were evaluated. The study group included 716 patients (371 male, 345 female) with non-syndromic agenesis of at least one tooth (except the third molars). The study data were assessed using descriptive statistics, chi-square test, and Mann–Whitney U test, while patterns were evaluated using a tooth agenesis code (TAC) tool. Results A total of 1,627 congenitally missing teeth, were found in patients with non-syndromic tooth agenesis, with an average of 2.27 missing teeth per patient. The prevalence of tooth agenesis was 7.25%, and the most commonly missing teeth were the left mandibular second premolars (10.17%). The age group comparison revealed no significant difference in the median number of missing teeth per patient according to the cutoff values for ages between 12 and 22 years. When the missing teeth were examined separately according to quadrants, 114 different tooth agenesis patterns (upper right quadrant = 28, upper left quadrant = 27, lower left quadrant = 31, and lower right quadrant = 28) were identified, and 81 of these patterns appeared only once. Conclusions This study highlights the benefits of applying the TAC tool in a large sample population. The application of the TAC tool in such studies will enable the development of template treatment plans by determining homogenous patterns of tooth agenesis in certain populations.

Aim: To determine whether a relationship exists between the periocular anthropometric meas-urements (POAM), intercanine width, and Little’s irregularity index (measures the crowding of mandibular incisors) in the Turkish population. Methodology: Ninety-four children (49 with mandibular crowding and 45 controls) aged between 12-18 years were included in this study. Inter-outer canthal distance (IOCD), in-ter-inner canthal distance (IICD), interpupillary distance (IPD), inter-canine width (ICW), and Littles’irregularity index (LII) of subjects were measured from two standardized digital pho-tographs using a public domain Java processing program (ImageJ software). Spearman correla-tion coefficient and multiple linear regression tests were used to investigate the relationship between POAM, and ICW, and LII. Results: In the mandibular crowding group, the means of IICD, OICD, IPD, and ICW were 30.6 ± 1.7 mm, 82.4 ± 2.0 mm, 59.2 ± 1.6 mm, 23.3 ± 1.1 mm, respectively. In controls, the mean of the measurements was found to be 32.1 ± 1.5 mm, 84.4 ± 2.4 mm, 60.1 ± 1.9 mm, 24.6 ± 1.4 mm, respectively. There were statistically significant differences between groups among all variables (p <0.001). There was a negative correlation between POAM and ICW with LDI. Especially, high correlation was found in ICW and IICD variables (r = -. 732, p <.001 and r = -705, p <.001, respectively). As a result of multivariate regression analysis, IICD and ICW were found to be affected the crowding negatively and significantly (p = .003 and p = .026, respectively). Conclusion: According to the results obtained from our study, it was concluded that IICD which remains stable after the age of 10 years and ICW can be used to predict irregularities in mandibular incisors in children in the Turkish population.   How to cite this article: Kızıltan Eliaçık BB.
