Is diagnosing exposed dentine a suitable tool for grading erosive loss?Holbrook WP; Ganss CClin Oral Investig 2008[Mar]; 12 Suppl 1 (Suppl 1): S33-9Quantifying tooth wear in general and erosion in particular mostly is made by distinguishing between lesions restricted to enamel and lesions reaching the underlying dentine. Various scores for grading have been used, but in all systems, higher scores are given in cases of exposed dentine, thus, indicating a more severe stage of the condition. Clinical diagnosis of exposed dentine is made by assessing changes in colour or optical properties of the hard tissues. This paper aims to review the literature and discuss critically problems arising form this approach. It appears that classifying the severity of erosion by the area or depth of exposed dentine is difficult and poorly reproducible, and taking into account the variation of enamel thickness, the amount of tissue lost often is not related simply to the area of exposed dentine. There has still been very little longitudinal investigation of the significance of exposed dentine as a prognostic indicator. Further work and discussion is needed to reevaluate the explanative power of current grading procedures.|Dental Enamel/pathology[MESH]|Dentin/*pathology[MESH]|Humans[MESH]|Odontometry/standards[MESH]|Reproducibility of Results[MESH]|Severity of Illness Index[MESH]|Tooth Abrasion/classification/*diagnosis/pathology[MESH]|Tooth Attrition/classification/*diagnosis/pathology[MESH]|Tooth Erosion/classification/*diagnosis/pathology[MESH] |
