Oral mucosa is encountered by various lesions and normal variants. Some are not to be worried about, whereas others may be of significance. Knowing the prevalence of oral mucosal lesions in a particular region helps better evaluate, diagnose, and, thus, manage these lesions.
To assess the prevalence and distribution of oral mucosal lesions and normal variants among various age groups, genders, and sites of the orofacial region.
This cross-sectional study was conducted in the Department of Oral Medicine and Radiology, KIST Medical College and Teaching Hospital from January 2021 to March 2021. Three different proformas were designed according to age, gender, and location of lesions for entry as per the WHO's guide. The obtained data were entered into a Microsoft Excel sheet for frequency analysis by SPSS, and the results were tabulated.
Among the records of 16572 (9703 (58.55%) males and 6869 (41.44%) females) OPD patients, 3495 (21.08%) (1934 (55.33%) males and 1561 (44.66%) females) had OMLs and 2314 (13.96%) (1626 (70.26%) males and 688 (29.73%) females) had normal mucosal variants. The most commonly seen OML categories were tobacco-associated lesions, i.e., 2056 (34.07%), tongue lesions, i.e., 1598 (26.48%), oral potentially malignant disorders, i.e., 815 (13.50%), ulcers i.e., 728 (12.06%), and infectious lesions, i.e., 256 (4.24%).
The Nepalese population has a wide range of oral mucosal lesions and normal variants, and this study has attempted to have baseline data for the same. The most common OML was smoker's melanosis.
口腔黏膜可出现各种病变和正常变异。有些无须担心，而有些则可能具有重要意义。了解特定地区口腔黏膜病变的患病率有助于更好地评估、诊断和管理这些病变。
评估不同年龄组、性别和口腔颌面部位的口腔黏膜病变和正常变异的患病率和分布。
本横断面研究于 2021 年 1 月至 2021 年 3 月在 KIST 医学院和教学医院的口腔医学和放射科进行。根据世界卫生组织的指南，设计了三个不同的表格，根据年龄、性别和病变位置进行录入。将获得的数据输入 Microsoft Excel 工作表，使用 SPSS 进行频率分析，并将结果制成表格。
在 16572 例（9703 例男性[58.55%]和 6869 例女性[41.44%]）门诊患者的记录中，3495 例（21.08%）（1934 例男性[55.33%]和 1561 例女性[44.66%]）有口腔黏膜病变，2314 例（13.96%）（1626 例男性[70.26%]和 688 例女性[29.73%]）有正常黏膜变异。最常见的口腔黏膜病变类别是与烟草相关的病变，即 2056 例（34.07%）、舌病变，即 1598 例（26.48%）、口腔潜在恶性疾病，即 815 例（13.50%）、溃疡，即 728 例（12.06%）和感染性病变，即 256 例（4.24%）。
尼泊尔人群有广泛的口腔黏膜病变和正常变异，本研究试图为此提供基线数据。最常见的口腔黏膜病变是烟斑。
