There has been shown a relationship between "tongue coating" and "Simplified Oral Health Index, periodontal status, modified mallampati classification (MMC) of the oropharynx and oral malodor". The purpose of this study is to assess the frequency of tongue coating and relative factors (sex, age, smoking, systemic disease and oral health indices) among patients referred to Dental School of Kerman University.
In this cross sectional study 250 patients referred to dental school of Kerman university of medical sciences were examined. The data collection form was included demographic data (gender, age, history of systemic disease and smoking) and Oral health indices such as TCI (Tongue coating index), OHI-S (Simplified Oral Hygiene Index), MGI (Modified Gingival Index), MMC and lost teeth. The analysis have been done using SPSS21, T-test, Pearson correlation coefficient and linear regression analysis (significance level was set at less than 0.05).
Tongue coating has been shown in 96% of patients with the mean percent of 45.83 ± 19.16%. Men had higher percent of TCI though it was not statistically significant. Smoking was the strongest determinant factor in people with higher TCI scores (P = 0.013). There was a positive significant correlation between OHI-S and TCI [(Pearson's coefficient(r) = 0.134, P = 0.034)].
TCI appears to be related to smoking and Simplified Oral Health Index. The evaluation of tongue coating is necessary to assess its impact on oral health status and also to motivate patients to clean their tongue as a part of their oral health care routine.
“舌苔”与“简化口腔健康指数、牙周状况、改良的口腔后咽腔 Mallampati 分类（MMC）和口腔异味”之间存在关联。本研究旨在评估克曼大学牙科学院就诊患者舌苔的频率及其相关因素（性别、年龄、吸烟、系统性疾病和口腔健康指数）。
在这项横断面研究中，对 250 名克曼大学医学科学牙科学院就诊患者进行了检查。数据收集表包括人口统计学数据（性别、年龄、系统性疾病史和吸烟史）以及口腔健康指数，如 TCI（舌苔指数）、OHI-S（简化口腔卫生指数）、MGI（改良龈指数）、MMC 和失牙数。采用 SPSS21 进行分析，包括 T 检验、皮尔逊相关系数和线性回归分析（显著性水平设定为小于 0.05）。
96%的患者存在舌苔，平均百分比为 45.83±19.16%。男性的 TCI 百分比较高，但无统计学意义。吸烟是 TCI 评分较高人群的最强决定因素（P=0.013）。OHI-S 与 TCI 呈正相关（皮尔逊相关系数(r)为 0.134，P=0.034）。
TCI 似乎与吸烟和简化口腔健康指数有关。评估舌苔有助于评估其对口腔健康状况的影响，并促使患者清洁舌苔，作为其口腔保健常规的一部分。
