Case‐control study of non‐carious cervical lesions

Abstract

An exploratory case-control study of non-carious cervical lesions was undertaken to examine the effects of a variety of risk factors. Candidate exposure variables were related to erosion, abrasion, and tooth flexure, the three principal putative causal mechanisms for cervical lesions. Because previous studies have tended to focus on specific causal mechanisms, evidence for a multifactorial etiology is inconclusive. Data describing exposure factors were obtained through clinical examination, dietary and behavioral questionnaires, and analysis of study casts from 264 subjects (137 cases, 127 control). Salivary data were also obtained for a subset of these subjects. Patient and tooth-level logistic regression models were constructed for the full subject group, and the subset with salivary data. For the two patient-level models, only exposures related to brushing entered. For tooth-level models, multiple exposures representing all three causal mechanisms were included in both models. The results suggest that non-carious cervical lesions do have a multifactorial etiology, and that multiple causal mechanisms may operate in the initiation and progression of individual lesions.

Prevalence and risk factors for non-carious cervical lesions in children attending special needs schools in India

“…The cause of NCCLs is multifactorial (3,4), which makes it difficult to describe their etiology precisely (2,3,5). It is generally agreed that NCCLs are caused by a combination of abrasion, erosion, and tooth flexure (2).…”

“…The etiology of tooth wear is a multifactorial phenomenon involving acids and other tooth-softening chemicals, abrasion, tooth flexure 2) and attrition, each playing a role to a greater or lesser degree from patient to patient and tooth to tooth 1,3,4) . The most common causes of excessive palatal wear are attributed to parafunctional activities such as bruxism, chemical erosion due to the introduction of gastric acid into the oral cavity occurring with repeated regurgitation 3) , and eating disorders such as anorexia nervosa or bulimia 5) .…”

“…Klinik ve deneysel çalışmalar kişilerdeki aşınma mekanizmasının nadiren tek başına ilerlediğini, genellikle birbiriyle etkileşim içinde olduğu-nu göstermiştir. 2,3 Klinikte, keskin, belirgin kenarları, sert ve pürüzsüz yüzeyleri bulanan abrazyon lezyonlarına erozyon da eşlik ederse daha yuvarlak, geniş ve sığ bir şekilde izlenir. Abfraksiyon lezyonları ise keskin çizgi açıları bulunan kama şeklindeki lezyonlar olarak karşımıza çıkar.…”
