Abstract:
Aim: The aim of this study is to determine the relationship between gingival biotype and delayed eruption using the probe transparency
technique in different age groups. The hypothesis of the present study is that the thick gingival biotype may lead to delayed eruption.
Material and Methods: A total of 131 patients (mean age, 90.21± 27.76 months), including 68 males and 63 females were included
in the study. Patients were examined in 3 groups according to their dentition periods: between the ages of 3-5 years in Group 1
(G1), 6-8 years in Group 2 (G2), and 9-12 years in Group 3 (G3). Clinically, the gingival biotype was recorded by probe transparency
technique. Dental age of the patients was evaluated according to Demirjian method on digital panoramic radiographs. Statistically
the chi-square test was used for analysing between the gingival biotype and delayed eruption.
Results: The thick gingival biotype was observed in 88.4% and 79.1% in the maxilla and mandible in G1, respectively. In G2, thick
biotype-related maxillary delayed eruption was observed in 35% of patients. In G3, the patients who have a thin gingival biotype in
mandibular arch showed premature eruption.
Conclusion: Delayed eruption may be related especially in thick gingival biotype in maxillary arch
