Background: Supernumerary teeth numerical anomalies and the early diagnosis of supernumerary teeth is very important to avoid potential complications. The study aim was to determine the prevalence, occurrence, and characteristics of supernumerary teeth among the Arabian population. Methods: A retrospective radiographic study was performed using panoramic radiographs of patients attending a teaching hospital from January 2018 to December 2020. Only healthy patients with clear radiographs were included in the study, and patients with syndromes, cleft lip, and palate, and unclear radiographs were excluded from the study. The details include the patient’s age and gender, supernumerary tooth number, location, orientation, and position. Only a single examiner was involved in the data collection and analysis. Results: Overall, 38 (2%) patients were observed with 47 supernumerary teeth. Among them, 76% were males and 24% were females, with a mean age of 16.1 ± 9.7 years. Mesiodens (87%) are the common type of supernumerary tooth, and the majority of the supernumerary teeth were impacted (66%). The majority of the patients presented with a single supernumerary tooth, while 24% of the patients presented with two supernumerary teeth. Sixty percent of the supernumerary teeth were conical in morphology, followed by a tuberculate morphology. In the study population, most of the supernumerary teeth were normal in orientation. Conclusions: The prevalence of supernumerary teeth was 2%. Among them, the majority were observed at the anterior region of the maxillary arch with a conical shape of normal orientation. The gender-based comparison of location, orientation, morphology, eruption, and number of supernumerary teeth showed male predilection.

Background: The treatment modality of using gingival veneer prosthesis for anterior gingival recession is not widely known even in the dental fraternity. This survey has been conducted considering its essential nature and absence of data on its awareness in the Riyadh region.Aims: The aim of the study was to assess the knowledge, awareness, and practice of gingival veneer prosthesis among dental students, interns, and practitioners in the Riyadh region.Materials and Methods: A descriptive cross-sectional electronic survey was conducted on dental students, interns, and practitioners of both genders in Saudi Arabia, using a convenient sampling method. The final questionnaire consisted of 12 questions. The percentage of various responses, with reference to the demographics, and statistical significance, were tested by independent sample t-test and p-value <0.05. The responses/data of 446 participants were tabulated and processed in SPSS (version 21.0).Results: The preferred treatment option for an anterior gingival recession proposed by prosthodontists was prosthetic correction (p<0.05), and for other groups, it was periodontal surgery (p<0.05). 66% of general practitioners’ group and 56% of dental students and interns’ group, respectively, were not sure about the ideal treatment option for Miller’s class III & IV gingival defects, while 70% of general practitioners’ group and 65% of the students and interns’ group, respectively, were not sure about the ideal treatment option for the management of gingival tissue loss between implants,.Conclusion: There is a significant lack of knowledge on using gingival veneer prosthesis as a treatment option for anterior gingival defects among general dental practitioners, interns, and dental students (p˂0.05).

The present study aimed to evaluate the sex dimorphism in morphometrics of permanent canines using mesiodistal and cervicoincisal widths in the Saudi Arabian population. The study was performed using dental casts of patients attending the prosthodontics department, College of Dentistry, Majmaah University, Saudi Arabia. The inclusion criteria involved the presence of all four permanent canines (maxillary left and right (13 and 23) and mandibular left and right (33 and 43)) without any form of developmental anomalies or dental caries with a complete eruption. Mesiodistal width and cervicoincisal width were measured using a digital caliper, ensuring precision and consistency. Statistical tests included t-tests and correlation analyses using IBM Statistics (version 21) with p ≤ 0.05 significance level. A total of 94 sets of dental casts of patients with a mean age of 24.6 ± 4.06 were available in the study for evaluation. Tooth 13 was found to have a higher mesiodistal width (8.12 ± 0.57 mm), while tooth 43 was observed to have a higher cervicoincisal width (9.3 ± 0.9 mm). The study observed gender-based differences in mean scores, with females generally having slightly lower mean scores in mesiodistal and where males (p < 0.05) observed with slightly low cervicoincisal widths compared to females. Positive correlations were found between age and mesiodistal and cervicoincisal scores across various dimensions (p < 0.005). There was evidence of difference in mesiodistal and cervicoincisal widths among antimeres. The percentage of sex dimorphism varied across dimensions, with some showing more pronounced gender-related differences. The study establishes the mesiodistal and cervicoincisal widths of all permanent canines can be used to identify sex dimorphism in the Saudi Arabian population.
