Noncarious Cervical Lesions—An Approach to the Associated Factors: A Cross-sectional Study

Various types of risk factors have been associated with an increased likelihood of developing NCCLs.These include physical, chemical, mechanical, and occlusal factors, as well as nonphysiological influences such as personal lifestyle choices, habits or behaviors, medical conditions, environmental exposures, and congenital traits. 6In addition, there are factors inherent to dental structure.The cervical region of the tooth is particularly vulnerable because the proportion of enamel decreases, mineral content is reduced, and the amount of proteins increases.Furthermore, this area IntroductIonNoncarious cervical lesions (NCCLs) are clinically recognized as a progressive loss of dental tissue at the cementoenamel junction (CEJ).They vary in extent and present characteristic shapes, typically affecting the enamel and dentin, and in more advanced stages, may extend to involve the dental pulp. [1][2]][3][4] According to the terminology established by the European Organization for Caries Research (ORCA) and the Cariology Research Group of the International Association for Dental Research, physiological dental wear refers to the degree of wear resulting from the natural function of the stomatognathic system over a person's lifetime.The rate of progression varies among individuals, and not all worn teeth require treatment.Dental wear is considered less when it exceeds physiological levels for a person's age and negatively affects their self-perceived wellbeing. 5ccording to the Dental Wear Assessment System, wear is classified as pathological when it appears in a moderate to severe form on the tooth surface and is accompanied by one or more signs and symptoms.These may include hypersensitivity and/ or pain, functional issues (such as difficulty chewing or eating), compromised esthetics, wear atypical for the patient's age, disintegration of dental hard tissues and restorations, and risk to the structural integrity of the teeth, among others.
