Occlusal Characteristics of The Primary Dentition in Salah Al-Din City

Abstract

Occlusal characteristics that are found in the primary dentition have a substantial role in the occlusal characteristics which will appear in permanent dentition. Consequently, a good background of Occlusal characteristics in children is substantial for dental practitioners. Use an observational, cross-sectional study on selected children randomly in Salah Al-Din to define the occlusal characteristics of primary dentition in the group of Salah Al-Din's children. Objective: Collecting more data and information about the occlusal characteristics of primary dentition in a group of Salah Al-Din's children. Methods: In randomly form selected 413 children between 3 and 6 years old from Salah Al-Din governorate as the sample. Under natural daylight or room light, the examination was done on all children to observe needed characteristics with the inclusion criteria. Prevalence of different types of terminal plane, primary canine relationship, anterior and posterior crossbite overjet, overbite, and primate spaces of the primary dentition were estimated. In the terminal plane we see that the flush terminal plane is the most prevalent type (63.20%). In a primary canine relationship, Class I was the most common type (80.39%). The ideal form of overjet was most common (88.86%). The most common form of overbite was the normal overbite (82.32%). Anterior and posterior have low prevalent (3.63%,1.94% respectively). Observed that primate space was present in 71.19% of the upper arch, and 60.05% is the ratio of mandible space. Conclusion: Most of the sample has desirable occlusal characteristics such as Flush terminal plane, Class 1 canine relationship, normal overjet etc., and undesirable occlusal characteristics have low prevalence as anterior open bite, reverse overjet..etc.
