Objective: The aim of this study was to determine the prevalence of ponticulus posticus (PP) located on the atlas vertebrae of individuals who applied to Necmettin Erbakan University, Faculty of Dentistry, Department of Dentomaxillofacial Radiology for various reasons whose lateral cephalometric radiographs were taken, to determine their relationship with gender and age group, and to analyze our findings in the scientific literature comparison with similar studies.
Material and Method: The presence and types of PP were investigated on 835 lateral cephalograms. Each patient was assigned an identification number, and demographic information, absence/presence of PP, if present, type of PP was recorded. Distributions of obtained values were analyzed using Pearson’s Chi-square test. p values < 0.05 were considered statistically significant.
Results: The mean age of subjects was 16.90 ± 5.73 years (range 7–55). In the analyzed sample, PP had a prevalence of 25.1 % (complete form 11.0 %, incomplete form 14.1 %). There was a significant difference between genders (p = 0.001) (more prevalent in male patients: 110/347; 31.7 %). No significant difference was found between age groups (p > 0.05).
Conclusion: PP is not a rare anomaly and the patient must be told of the implications and importance of detecting PP on a lateral cephalogram. Further studies are needed to widen the sample, verify possible regional variations and improve the analysis by more advanced radiological examinations such as CT and cone beam CT scans.
