Dentinal hypersensitivity is a widespread condition characterized by a brief, sharp pain arising from exposed dentin in response to external stimuli, which cannot be linked to any other dental conditions. This study aimed to estimate the prevalence of dentinal hypersensitivity among patients attending a tertiary health care center.
A observational cross-section study was conducted, involving 376 patients aged 10-70 years who visited a tertiary care center. Convenience sampling was employed to select participants, and the prevalence of dentinal hypersensitivity was assessed through a questionnaire. Data were collected from the Department of Oral Medicine and Radiology after obtaining ethical approval Institutional Review Committee (Reference number: 385 (6-11) E2 079/80). The analysis was performed using Microsoft Excel, and descriptive statistics were reported .
There were 376 patients in the study and the prevlence of dentin hypersensitivity wasa 236 (62.77%; CI 95%: 57.66%-67.67%). Among those diagnosed, 138 (73.02%) were male, and 98 (52.41%) were female. The age-specific prevalence was found to be 30 (50.85%) in patients aged 10-19 years, 73 (63.48%) in those aged 20-29 years, 42 (53.16%) in patients aged 30-39 years, 23 (51.11%) in those aged 40-49 years.
This study identified a high prevalence of dentin hypersensitivity among the patient population, with variations observed across different age and sex groups.
牙本质过敏是一种普遍存在的病症，其特征为暴露的牙本质对外部刺激产生短暂、尖锐的疼痛，且无法与任何其他牙科疾病相关联。本研究旨在评估在一家三级医疗保健中心就诊的患者中牙本质过敏的患病率。
进行了一项观察性横断面研究，纳入了376名年龄在10至70岁之间、前往三级医疗中心就诊的患者。采用便利抽样法选取参与者，并通过问卷调查评估牙本质过敏的患病率。在获得机构审查委员会（参考编号：385 (6 - 11) E2 079/80）的伦理批准后，从口腔医学与放射科收集数据。使用Microsoft Excel进行分析，并报告描述性统计结果。
本研究中有376名患者，牙本质过敏的患病率为236例（62.77%；95%置信区间：57.66% - 67.67%）。在确诊患者中，男性有138例（73.02%），女性有98例（52.41%）。发现10至19岁患者的年龄特异性患病率为30例（50.85%），20至29岁患者为73例（63.48%），30至39岁患者为42例（53.16%），40至49岁患者为23例（51.11%）。
本研究发现患者群体中牙本质过敏的患病率较高，且在不同年龄和性别组中存在差异。
