A system for assessing the severity and progression of occlusal tooth wear

Abstract

This study represents an attempt to introduce a system for the longitudinal evaluation of the severity and the rate of progression of tooth wear. The material comprised a selected group of 10 males and 10 females, examined twice within an 18-month period. The subjects were predisposed to advanced occlusal wear and had a mean age of 32 years within the range of 16-56 years. Evaluation of occlusal wear was performed on a tooth-by-tooth basis, on study casts, using two ordinal scales, one for assessing the severity, and the other the progression of occlusal wear. The reliability of the scales was assessed by percentage inter-observer concordances. The sample exhibited higher occlusal wear scores in the incisor and canine regions compared to the posterior region. It was found that the overall progression in an 18-month follow-up period was slow. The inter-observer concordance in the evaluation of the severity of wear was 88%, and 91% in the progression of wear. Within the limitations of the described system, the scales may be utilized for determining the severity of occlusal wear and the rate of its deterioration in an individual's dentition. From a clinical standpoint, the need for future treatment may be based on such a evaluation of the progression of wear.

“…The intraoral examination was conducted to assess for tooth wear. An ordinal scale 28,29 was used for grading the severity of occlusal wear. Table 1 shows the criteria used to grade the tooth wear severity in the present study.…”

Effect of dental wear, stabilization appliance and anterior tooth reconstruction on mandibular movements during speech

“…Bruxism has been found to be the decisive factor in dental attrition affecting the degree of tooth damage (12), and contributing to the progression of wear (13). It can lead to an excessive reduction of clinical crown height (12) and often requires restorative intervention (14).…”

“…El desgaste dentario, ha sido descrito como un indicador débil del bruxismo nocturno actual y no discrimina entre el rechinamiento y el apriete dentario Johansson et al, 1993;Lavigne et al, 1996). Pacientes que presentan rechinamiento dentario moderado a severo (detectado en un laboratorio de sueño) pueden no presentar grandes facetas de desgaste, mientras que otros, con un leve rechinamiento, desarrollan grandes evidencias de desgaste, lo que podría deberse a variaciones en la densidad del esmalte (Johansson et al;Lavigne et al, 1996;Thie et al, 2002).…”
