Cervical abrasion is a multifactorial process due to the use of abrasive dentifrices along with improper brushing patterns. An extensive lesion may cause loss of structural integrity of tooth and esthetically unacceptable. The purpose of the study was to assess the prevalence of cervical abrasion with age, gender, and oral hygiene practices among workers in a spinning mill, Kerala. The study also aimed to identify the buccolingual measurements of each abraded tooth using the Community Abrasion Index of Treatment Needs (CAITN) probe.
A cross-sectional study where 366 subjects (257 males and 109 females) above 20 years of age were selected using a random sampling technique. Data was collected from the assessment form comprising demographic data and oral hygiene practices of the subjects. Clinical examination for abrasion and buccolingual measurements of abraded tooth recorded using CAITN probe. The statistical analysis was done using SPSS 26.0. for calculating descriptive statistics, Chi-square test, and binary logistic regression.
The overall prevalence of abrasion was 37.2% and 97.7% of subjects with abrasion had sensitive teeth and were statistically significant. Age, gender (males) and combined horizontal and vertical method of brushing technique were strongly associated with the cervical lesion ( < 0.001). Binary logistic regression analysis showed that age group, gender, combined horizontal and vertical method of brushing, and presence of sensitive tooth was associated with the abrasion.
It is concluded that the severity of the abrasion is an age-related phenomenon associated with combined horizontal and vertical strokes of brushing and is common among the male population. Dentinal hypersensitivity is also more prevalent with cervical abrasion. The novel CAITN probe can be used as an effective tool to assess the cervical abrasion and its treatment needs.
由于使用磨砂牙膏以及不正确的刷牙方式，颈部磨损是一个多因素过程。广泛的病变可能导致牙齿结构完整性丧失且美观性不佳。本研究的目的是评估喀拉拉邦一家纺纱厂工人中颈部磨损随年龄、性别和口腔卫生习惯的患病率。该研究还旨在使用社区治疗需求磨损指数（CAITN）探针确定每颗磨损牙齿的颊舌径测量值。
采用随机抽样技术选取366名20岁以上的受试者（257名男性和109名女性）进行横断面研究。从包含受试者人口统计学数据和口腔卫生习惯的评估表中收集数据。使用CAITN探针记录磨损情况的临床检查以及磨损牙齿的颊舌径测量值。使用SPSS 26.0进行统计分析，以计算描述性统计量、卡方检验和二元逻辑回归。
磨损的总体患病率为37.2%，97.7%的磨损受试者有牙齿敏感，且具有统计学意义。年龄、性别（男性）以及水平和垂直相结合的刷牙方法与颈部病变密切相关（<0.001）。二元逻辑回归分析表明，年龄组、性别、水平和垂直相结合的刷牙方法以及牙齿敏感的存在与磨损有关。
得出的结论是，磨损的严重程度是一种与水平和垂直相结合的刷牙方式相关的年龄相关现象，在男性人群中较为常见。牙本质过敏在颈部磨损中也更普遍。新型CAITN探针可作为评估颈部磨损及其治疗需求的有效工具。
