Prevalence of dentine hypersensitivity in Chinese rural adults with dental fluorosis

Abstract

Summary The aim of this study was to estimate the prevalence of dentine hypersensitivity (DH) among residents of rural China with dental fluorosis aged 30–69 years. A village located in northern China in which dental fluorosis was common was selected. Some 1250 residents with fluorosis ranging in age from 30 to 69 years completed a structured questionnaire and underwent clinical examination. Diagnosis of DH was based on the combination of the subject's self‐evaluation and clinical examination. Dental fluorosis was evaluated using Dean's index (DI). In the village, the fluoride concentration in drinking water was 1·15–1·50 mg L−1. The community fluorosis index was 1·47, and 74 (9·7%) of the participants with dental fluorosis were diagnosed with DH. There was no significant difference between men and women. DH was most commonly observed in the lower incisors, and the most common cause of DH was cold stimulation. Logistic regression analysis showed acid reflux to be the only risk factor for DH in the current study. Among subjects with DH, none took treatment measures, visited a hospital or clinic, or used antisensitivity toothpaste. The prevalence of DH in the selected subjects with dental fluorosis was 9·7%. Acid reflux was found to be a risk factor for DH in the current study.

A cross‐sectional study of dentine sensitivity in periodontitis patients in Trinidad and Tobago

“…Like many studies, the most common initiating factor of DS in this study was cold stimuli . Acidic or sour foods were reported by 11.6% of patients as initiators of DS symptoms in the Trinidadian study.…”

“…The most common initiating factor in these DS studies (Table ) has been cold stimuli . Hard and acidic foods were significantly associated with DS among Thai dental patients .…”

“…Prevalence of DS amongst adults based on a literature review from 1964 to present (Table ) revealed a wide range in values from 1.3% to 73.0%. These differences in the prevalence may be related to the methodology of DS determination, with questionnaires probably overestimating the findings due to subjectivity in DS self‐reporting as opposed to more stringent measures of clinical determination.…”

Biomarkers of chronic fluoride exposure in groundwater in a highly exposed population

“…The children in our study were the most affected by severe EF, with pitting and loss of permanent teeth, and increased tooth sensitivity were widely observed among the young children enrolled in the study. Such effects and increased risk of tooth decay have previously been documented in studies from other locations (Levy 2003; Burt and Eklund, 1999; Wondwossen et al, 2004; Mine et al, 2011; Zhang et al, 2014), and EF has also been linked to psychological and social impacts due to stigma arising from the brownish discoloration of individuals' teeth (Wondwossen et al, 2006). Consistent with these impacts, many individuals that participated in the study reported an inability to chew hard foods (loss of dental function) from a young age, which harms the overall quality of life.…”

Reliability and validity of the Chinese version of the short form of the Dentine Hypersensitivity Experience Questionnaire (DHEQ-15)

“…Dentine hypersensitivity (DH) is a common oral complaint characterized by 'short, sharp pain arising from exposed dentin in response to stimuli typically thermal, evaporative, tactile, osmotic, or chemical and which cannot be ascribed to any other form of dental defect or pathology' [2]. It is a highly prevalent oral condition, affecting 9.7-34.1 % of Chinese people [3][4][5]. This oral disorder not only affects patients' physical health, but also affects their social functions and psycho-social well-being [6][7][8].…”
