Non-carious cervical lesions (NCCLs) are often encountered in clinical practice and their aetiology attributed to toothbrush abrasion, erosion and tooth flexure. This paper aims to determine the prevalence and severity of NCCLs in a sample of patients attending a university clinic in Trinidad and to investigate the relationship with medical and dental histories, oral hygiene practices, dietary habits and occlusion. Data were collected via a questionnaire and clinical examination. Odds ratios were used to determine the association of the presence of lesions and the factors examined. One hundred and fifty-six patients with a mean age of 40.6 years were examined of whom 62.2% had one or more NCCLs. Forty five per cent of the lesions were sensitive to compressed air. Younger age groups had a significantly lower correlation with the presence of NCCLs than older age groups. Other significant factors included patients who reported heartburn, gastric reflux, headaches, bruxism, sensitive teeth and swimming or had a history of broken restorations in the last year. There was also significant correlation of NCCLs in patients who brushed more than once a day or used a medium or hard toothbrush. Patients with vegetarian diets and those who reported consuming citrus fruits, soft drinks, alcohol, yoghurt and vitamin C drinks were associated with the presence of lesions. Significant associations were also found in patients with group function, faceting, clicking joints or those who wore occlusal splints.

    • "A 6-year longitudinal clinical study showed that consumption of dietary acids and frequency of tooth brushing correlated with increased prevalence of the lesions [8]. An epidemiologic study with 156 patients in Trinidad and Tobago showed that a high frequency of tooth brushing and consumption of citrus fruits were related to the lesions [3]. However, the effect of occlusal loading on NCCLs remains unclear [9] [10]. "

    ABSTRACT: PURPOSE: Whether or not occlusal contact patterns cause non-carious cervical lesions is controversial. The aim of this study was to clarify the relationship between occlusal contact pattern and non-carious cervical lesions in male Japanese adults. SUBJECTS AND METHODS: A total of 386 male employees were enrolled. All participants were in the age range 30–59 years, participated in a dental examination, had posterior occlusal support, and had not been treated for malocclusion or any temporomandibular disorder. All non-carious cervical lesions and fillings in the labial buccal surfaces of all teeth were recorded. Fillings were considered to be the same as non-carious cervical lesions. Information about tooth brushing habits was collected with a questionnaire. Chi-square tests and multivariate logistic regression analysis were performed. RESULTS: Fifty-eight percent of the subjects had non-carious cervical lesions. The first premolars showed the highest prevalence of non-carious cervical lesions. The presence of non-carious cervical lesions was associated with age (P < 0.001) and mediotrusive-side contact (P = 0.030), but not with laterotrusive-side contact (P = 0.073) or frequency of tooth brushing (P = 0.425), according to chi-square tests. Multiple logistic regression analysis showed that subjects with bilateral mediotrusive-side contact (adjusted odds ratio = 2.19 vs. no contact, P = 0.007) and laterotrusive-side contact in incisor-canine-premolar areas (adjusted odds ratio = 2.27 vs. incisor-canine areas, P = 0.036) were at increased risk of having non-carious cervical lesions after adjusting for age. CONCLUSIONS: Bilateral mediotrusive-side and laterotrusive-side contacts in incisor-canine-premolar areas were significantly associated with the presence of non-carious cervical lesions after adjusting for age in male adults.

    ABSTRACT: This paper is a literature review of various aspects of the wear of occluding tooth surfaces. It presents classification and terminology of occlusal tooth wear, and discusses etiology and differential diagnosis. It may be difficult to differentiate among abrasion, attrition, and erosion because there is nearly always a combination of the various processes. These processes of wear are described, and the in vitro and in vivo wear of some restorative materials is discussed. Treatment of severe tooth wear is considered difficult; prophylactic measures are therefore important. Some guidelines for restorative treatment of patients with extensive occlusal tooth wear are given, with special emphasis on the type of treatment, the vertical dimension of occlusion, the space available, and choice of material for the restorations.

    ABSTRACT: The aim of the study was to investigate some aspects of the oral health of male Saudi military inductees with special reference to soft-drink consumption, dental erosion, caries and fluorosis prevalences; a second aim of the study was to develop a system for assessing dental erosion. The material comprised a random selection of 95 individuals with a mean age of 20.9 years (range, 19-25 years). A questionnaire survey was made of each individual's dietary and oral hygiene habits and general and oral health, in addition to clinical, study cast, radiographic, and photographic examinations. The results showed that soft-drink consumption in the sample (x = 247 1/year) far exceeded that found in Western populations and that professional and self-administered dental care were generally scant. Twenty-eight percent of the maxillary anterior teeth showed pronounced dental erosion. Fluorosis was a common finding, and the number of untreated carious cavities was high. DMFT (mean = 10.0; DT = 7.7; MT = 0.5; FT = 1.8) and DMFS (mean = 18.3; DS = 12.6; MS = 2.5; FS = 3.2) were higher than those of comparable Western populations and showed an approximately threefold increase over a period of about 18 years as compared with that previously reported in a similar Saudi sample. In view of the high frequencies of dental erosion, untreated carious cavities, and fluorosis reported here and the strong indication of an increasing caries prevalence, the need for serious recognition of the implications in the planning of future dental health care program is stressed.
