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.

目的

本研究旨在调查2016年转诊至大不里士牙科学院患者中牙颌紊乱的患病率。

材料与方法

本研究采用横断面研究方法，选取该时期内收治的所有患者。患者的牙合分类基于安氏分类法，骨骼分类基于施泰纳分析法，覆盖和覆牙合值以及其他患者相关信息从拔牙科室记录和特定表格中导入。数据审核后，将个体患者表格录入计算机并进行分析。

结果

在牙齿状况方面，安氏I类错牙合、安氏II类错牙合和安氏III类错牙合的患病率分别为50%、36.8%和13.2%。在覆盖情况方面，13.9%的患者覆盖正常，67.1%的患者覆盖增加，8.9%的患者覆盖减小，10.1%的患者覆盖反牙合。在覆牙合方面，17.7%的患者覆牙合正常，53.2%的患者覆牙合增加，8.9%的患者覆牙合减小，15.2%的患者开牙合，5.1%的患者深覆牙合。骨骼方面，24.1%的患者有安氏I类骨骼异常，62%的患者有安氏II类骨骼畸形，13.9%的患者有安氏III类骨骼畸形。
