Evaluation of the effect of smokeless tobacco on periodontal health and oral hygiene status
Background and objectives: Studies on effects of smokeless tobacco (ST) use on the periodontium are limited and have, received less attention. The aim of the present split mouth study is to evaluate the periodontal parameters and oral hygiene status of sites associated with smokeless tobacco (ST) placement and compares the corresponding parameters on the contralateral site, where smokeless tobacco is not placed (NST).
Methods: Study population: 25 subjects were selected from A.B. Shetty Memorial Institute of Dental Sciences, Deralakatte, Mangalore. Written informed consent was taken from all the participants. Oral cavity of each subject was divided into two sites Smokeless tobacco (ST) site and Non-smokeless tobacco (NST) site.
Screening examination included: Clinical examination of ST keratosis: the location, size, and specific teeth adjacent to the ST keratosis were recorded. Simplified Oral Hygiene Index (OHI-S), Gingival Index. Periodontal parameters-Probing depth (PD), Clinical attachment level, total number of teeth present in the mouth and number of teeth with attrition were recorded.
Results: Of the 25 subjects, mean OHI-S and gingival index was 2.76 and 1.36 respectively. Mean clinical attachment level was 2.78 (p- <0.001), number of teeth with recession and attrition was 3.36 and 3.04 respectively, all in favour of the ST site.
Interpretation and Conclusion: The smokeless tobacco site showed significantly greater gingival recession, attachment loss and periodontal deterioration when compared to nonsmokeless tobacco site.
KeywordsClinical attachment loss - Gingival recession, NST-site: Non smokeless tobacco site - Smokeless tobacco keratosis - STsite: smokeless tobacco site
