Evaluation of Malocclusion Pattern among Orthodontic Patients in Basrah City, Iraq

Malocclusion is defined as an irregularity or malalignment of the teeth or a malrelationship of the dental arches beyond the range of what is considered normal. Although the malocclusion is not considered a life-threatening condition, most of the focus in recent year was laid upon the development of orofacial disorders and treatment of resulting malocclusions and the seeking for orthodontic treatment is increasing in most countries to enhance the facial beauty and improve the facial appearance. The aim of current study was to evaluate the pattern of malocclusion among orthodontic patients attending the orthodontic clinic at College of Dentistry in Basra city, Iraq.

This study was based on clinical examination of 100 patients (46 males and 54 females) attending the orthodontic clinic with age range (4–30) years. Dental examination was done by an orthodontist. The measured parameters were recorded and analyzed using computer-based program (SPSS software, version 23).

According to the statistical analysis, class I malocclusion was the most prevalent type (55%) followed by class II (39%) and class III malocclusion (6%). Other occlusal traits included increased overjet (46%), normal overbite (55%), crossbite (23%) and scissor bite (1%), crowding and spacing (12% for each one). Chi-squared test showed a significant association between malocclusion and age, and a non-significant association between malocclusion and gender and decayed teeth.

Class I malocclusion was the most prevalent type of malocclusion, while class III was the least prevalent type. There is significant association between the malocclusion and age.
