Abstract

Aim

This study is aimed at investigating the prevalence of disorders among patients referred to Tabriz Dental School in 2016.

Materials and methods

This research was conducted in a cross-section method and taken from all patients admitted during this period. Classification of dental occlusion in patients was based on Angle's definition, skeletal classification was based on Steiner's analysis, and overjet and overbite values and other patient-related information were imported from the records in the extractive sector and in specific forms. After reviewing the data, the forms of individual patients were inputted into the computer and analyzed.

Results

In terms of dental condition, the prevalence of malocclusion CL.I, malocclusion CL.II, and malocclusion CL.III was respectively, 50, 36.8, and 13.2%. In terms of overjet condition, 13.9% of patients had normal overjet, 67.1% had increased overjet, 8.9% had reduced overjet, and 10.1% had reversed overjet. In terms of overbite, 17.7% of patients had normal overbite, 53.2% had increased overbite, 8.9% had decreased overbite, 15.2% had open bite, and 5.1% had deep bite. Skeletally, 24.1% of patients had skeletal abnormalities CL.I, 62% had skeletal deformities CL.II, and 13.9% had skeletal CL.III.

Conclusion

The most common dental malocclusion among patients was related to CL.I and the most common skeletal malocclusion was related to CL.II, and malocclusions of CL.III had the least prevalence both dentally and skeletally. There was no significant relationship between dental and skeletal malocclusions and also between different malocclusions and gender.

Clinical significance

Knowledge of the prevalence of different types of dental and jaw anomalies is considered as the first step in the evaluation and treatment of these disorders. It is worth mentioning that the results of the study can be used in treatment planning required in the province and even in the country.
