Abstract
Introduction: Tooth eruption time is affected by many factors. Eruption time of teeth and its sequence is important as part of dental treatment planning in Paediatric Dentistry, Orthodontics, as well as in Forensic Dentistry to estimate age of the child.
Aim: To estimate the eruption time of permanent teeth among school children aged 5-15 years in Duhok Governorate-Kurdistan Region, Iraq; in order to obtain a baseline data for treatment planning in clinical dentistry.
Materials and Methods: This was a cross sectional study comprising of 1418 healthy Kurdish children of both genders; 718 males and 700 females who were randomly selected by simple random method and examined from two kindergartens, four primary and four secondary schools in Duhok Governorate. The children were clinically assessed for tooth emerging through the oral mucosa. The mean and standard deviation of tooth eruption time for each tooth was estimated.
Results: Eruption time of permanent teeth tended to be earlier in girls than boys except for the teeth 11,14,15,21,24,25,31,34,35,36,41 and 44. The sequences of eruption of permanent teeth were 1-6-2-4-3-5-7 in the mandible, and 6-1-2-4-5-3-7 in maxilla in boys whereas it was 6-1-2-3-4-5-7 in the mandible, and 6-1-2-4-3-5-7 in the maxilla in girls.
Conclusion: The study provides information on eruption time for each tooth among Kurds children which can be useful in treatment planning in Paediatric and Orthodontic Dentistry.
