Abstract
Introduction: Dental ankylosis is one of the local factors that can influence tooth eruption. It always was observed in primary molars. Dental ankylosis might be leads to delay of eruption of successors tooth, ectopic eruption, arch length deficiency and peril the periodontal health of successors and neighboring permanent teeth. Timely diagnosis is imperative in prevention and control of occlusal disturbances.
Objective: Investigate the prevalence of dental ankylosis in primary schools children in Rasht.
Materials and Methods: This is a descriptive cross sectional study witch was performed on 1023 children in grade two and three. Exist of 1mm infraocclusion in compare to intact marginal ridge of neighboring tooth was consider as diagnostic criteria of ankylosis. In case of difficult diagnosis, occlusion of antagonist teeth and immobility were considered. Data was analyzed according to qui-square test.
Results: Prevalence of dental ankylosis was 15%. There was no significant difference between two sexes. Ankylosis was significantly more in mandible (p=0.001).The most affected teeth were observed first primary molars and the least involved teeth were upper second primary molars. More than 60% of subjects had more than one Ankylosed tooth. 9 aged children had the highest frequency of Ankylosed molars, but not significant between groups. In 2% of subjects, dental ankylosis was in upper larger than normal upper central incisors were observed.
Conclusion: According to high prevalence of dental ankylosis in this population during and the importance stage of alveolar growth and clinician’s knowledge about the problems is necessary intervention during routine dental examinations to reduce its complications and treatment costs.
