Background: Gingival and bone thickness is a prognostic agent in various therapeutic and regenerative procedures in dental procedures, in addition to recognition of a periodontal biotype in patients have a major meaning in the optimal design of preventive and therapeutic management mainly in periodontal and implant treatment. The aim to this study compares facial soft and hard tissue thickness in the anterior maxillary region in smokers and nonsmokers.
Methods: In this cross-sectional study 70 subjects who were periodontally healthy with at least 4 intact teeth in the anterior maxilla enrolled; They were divided into two equal groups of smokers and non-smokers, The thickness of gingiva was measured using an endodontic finger spreader (from 2, 5, 8 mm of the CEJ region) and the CBCT radiographs prepared from the upper anterior region, using the viewer software, the measurements were taken from the 1-distance of the CEJ to the bone crest 2-the facial bone width at the anterior maxilla (2, 5, and 8 mm from the apical to the CEJ). The information was evaluated using SPSS version 21 also the Mann-Whitney U test was used to compare differences between the two groups.
Results:The difference in the thickness of labial bone on the anterior maxillary region was not significant between smoker and non-smoker groups (P<0.05), while the labial gingival biotype in smoker patients was thicker than the non-smokers and the variation was significant (P<0.05).
Conclusion: The mean thickness of labial bone thickness and gingival dimension in the anterior maxilla was greater in smoker patients although there wasn't a correlation between them.
