Edirne'de Yaşayan Çocuklarda Süt Dişlerinin Sürme Zamanı ve Sıra Polimorfizmi: Kesitsel Bir Çalışma

Abstract

Objective: Variation in both the sequence and timing of primary tooth emergence across the different societies necessitates population-specific research. The aim of the present study is to determine median emergence times of primary teeth and the sequence polymorphism in Turkish children living in Edirne. Material and Methods: The research was performed on sample of 1315 children (684 boys and 631 girls) aged between 4-42 months, who were born and have been living in city of Edirne. Dental examination was carried out in family medicine centers by one investigator and primary teeth were assigned as 'emerged' when any part of it was appeared from the surface of gingiva. Median tooth emergence times were evaluated by probit regression analysis. Results: The first emerged teeth were mandibular central incisors with a median value of 6.9 months. The tooth emergence sequence was found as follows: mandibular central incisor, followed by maxillary central incisor, maxillary lateral incisors, a group with similar emergence timings; mandibular lateral incisor, mandibular and maxillary first molars, followed by canines and finally second molars in both arches. First molar and lateral incisor reverse sequence was found in 7% of girls in the maxilla, 5% of boys and 10% of girls in the mandible. 52-51 reverse sequence was found in 18% of boys and 9% of girls. 53-54 reverse sequence was detected in 6% of girls. Conclusion: The first standards of the timing and sequence of primary teeth emergence specific to children living in Edirne were provided.
