Association between primary dentition wear and clinical temporomandibular dysfunction signs.

Dental wear facets often are considered indicators of temporomandibular dysfunction (TMD). Dental wear facets are common in children, but their association with TMD signs is unknown. A reproducible, clinical evaluation of TMD signs for young children shows no statistically significant association between primary dentition wear facets and clinical signs of TMD (P less than or equal to 0.05). Wear facets in young children do not appear to warrant TMD evaluation or treatment.
