“…Whether or not bruxism causes noncarious cervical lesions is controversial. Many studies showed higher prevalence of NCCLs was in subjects with a bruxing habit than in subjects without a bruxing habit [26]. But other studies revealed that significant relationship between the two wasn't found [15,27].…”

Statement of the problem: An epidemiological cross-sectional survey was performed by trained, calibrated examiners, using a modified version of the TWI.Purpose: To survey the prevalence, characteristics of non-carious cervical lesion (NCCL) and analyze its relationship with life style. Methods:We surveyed 295 subjects including 187 males and 108 females who underwent oral health assessment in Nanfang Hospital. The shape, size, location of NCCL, tooth brushing habits, dietary habits, hand preference and bruxism were recorded for analysis.Results: NCCLs were found in 72.5% of subjects without gender difference. 70.6% affected teeth demonstrated v-shape. 61.2% of the lesions had axial depths of 1 to 2 millimeters. 73.4% of NCCLs were on posterior teeth, 55.6% on maxillary teeth. First premolars (32.3%) were mostly affected. The NCCLs was associated with age (P<0.01) and hard foods (P=0.03), but not bruxism (P=0.77) or frequency of tooth brushing (P=0.92). NCCLs were more common in right-hand tooth brusher (P<0.05 vs left-hander). The Odds Ratio of age, hand preference and hard foods on NCCLs were 1.1, 0.31 and 0.48, respectively. Conclusions:NCCLs were more common in posterior maxillary teeth, especially first premolars. Senior patients were more likely to have NCCLs. Aging, tooth brush and hard foods are risk factors for NCCLs.The main conclusions of this study the posterior mandibular teeth especially the first premolars followed by the molars were the teeth commonly involved. NCCLs were significantly related to age. No great difference in incidence was found between the right and left sides as a result of right or left hand dexterity. Aging, hard foods and tooth brush are risk factors for NCCLs. The limitations of this study: our survey based on a small sample. Large scale study or meta-analysis based on small samples analysis is needed in the future.

“…For example, Xhonga 6) found the prevalence of these lesions to be significantly higher in patients who were bruxists, while Lambrechts et al 7) found that bruxism and malocclusion were associated with abfraction lesions.…”

“…The abfraction is accelerated by excessive occlusal load such as occlusal interferences, premature contacts, bruxism, and clenching habit 10) . Loss of tooth structure in the cervical area of a NCCLs may cause esthetic problems and discomfort due to dentinal hypersensitivity 1,3,6) , but not all lesions require restorations 11) . The decision to restore NCCLs is based on the desire to strengthen the tooth and decrease the theoretical stress concentration and flexure, mitigate lesion progression, prevent hypersensitivity and pulp involvement, improve oral hygiene and enhance esthetics 11,12) .…”

The purpose of this study was to investigate the influence of various occlusal loading sites and directions on the stress distribution of the cervical composite resin restorations of maxillary second premolar, using 3 dimensional (3D) finite element (FE) analysis. Extracted maxillary second premolar was scanned serially with Micro-CT (SkyScan1072; SkyScan, Aartselaar, Belgium). The 3D images were processed by 3D-DOC-TOR (Able Software Co., Lexington, MA, USA). HyperMesh (Altair Engineering, Inc., Troy, USA) and ANSYS (Swanson Analysis Systems, Inc., Houston, USA) was used to mesh and analyze 3D FE model. Notch shaped cavity was filled with hybrid (Z100, 3M Dental Products, St. Paul, MN, USA) or flowable resin (Tetric Flow, Vivadent Ets., FL-9494-Schaan, Liechtenstein) and each restoration was simulated with adhesive layer thickness (40 ㎛). A static load of 200 N was applied on the three points of the buccal incline of the palatal cusp and oriented in 20�increments, from vertical (long axis of the tooth) to oblique 40�direction towards the buccal. The maximum principal stresses in the occlusal and cervical cavosurface margin and vertical section of buccal surfaces of notch-shaped class V cavity were analyzed using ANSYS. As the angle of loading direction increased, tensile stress increased. Loading site had little effect on it. Under same loading condition, Tetric Flow showed relatively lower stress than Z100 overall, except both point angles. Loading direction and the elastic modulus of restorative material seem to be important factor on the cervical restoration. [J Kor Acad Cons Dent 33(3):246-257, 2008]

“…Tooth wear is not caused by trauma and bacteria [2,3]. The etiological factors include consumption of acidic drinks and foods, bruxism, nail biting, wrong tooth brushing technique, types of dentifrice and using toothbrush with hard bristle [4,5,6,7]. A few studies reported that the prevalence is increasing due to the increasing population's age [8,9,10].…”

Abstract. Tooth wear is an oral lesion with multifactorial causes. The prevalence is increasing with an increasing age. Knowledge of tooth wear is part of oral health and essential requirements are needed to modify health related behaviors. This study was aimed to determine the knowledge, attitude and practice of tooth wear and to compare with the socio-demographic factors. A cross-sectional study using a modified version of self-administered questionnaire was distributed among 390 adults (aged more than 18 years old) from three government institutions in Bertam, Penang. A total of 349 (89.5%) subjects had participated in this study with 55.3% were males and majority of the subjects were Malays. About 58.2% had low level of knowledge with mean score at 20.8. Meanwhile, 93.4% subjects had a positive attitude and 84.2% had poor level of practice on oral hygiene. The low mean score of knowledge among subjects was not necessary an indicator that attitude and practice were affected. However, identification of etiological factors emphasizes on educational approaches, and empowerment of patients and community towards awareness are the most important factors for preventive strategies.
