Distribution of Tooth Loss in Periodontally Compromised Patients in Taiwanese Population: A Retrospective Cross-sectional Study
Objectives: To investigate the distribution of tooth loss in periodontally compromised patients in Taiwanese population.
Methods: 119 patients who have been diagnosed with generalized chronic periodontitis were recruited from Dental clinic of National Taiwan University Hospital from 2014-2015. All the patients received full-mouth periodontal examination including the number of residual teeth by a well-trained periodontist. All participants provided written informed consent, and all protocols were approved
by the Ethical Committee of National Taiwan University Hospital. The number, frequency and distribution of tooth loss was recorded. Moreover, the factors those might affect tooth loss was also investigated.
Results: The distribution of tooth loss showed no significant difference in gender and different age groups (P = 0.731, P=0.321, respectively). Tooth 36 seemed to be the highest frequent site with tooth loss, followed by tooth 27, tooth 37 and tooth 46. When considered by paired tooth position, lower first molar (tooth 36 and 46) seemed to be the most frequent positions with tooth loss, followed by upper second molar (tooth 17 and 27), lower second molar (tooth 37 and 47), and upper first molar (tooth 16 and 26).
Conclusions: The frequency or distribution of tooth loss may be associated with several factors, including the access to oral hygiene care, crown and root morphology and early erupted teeth.
