title: Relationship between condylar atrophy and tooth loss in craniomandibular disorders.
abstract: In order to investigate the relationship between condylar atrophy and tooth loss in craniomandibular disorders, we examined 37 patients with condylar atrophy (atrophy (+) group) and 109 patients without condylar atrophy (atrophy (-) group). No significant difference in the number of missing teeth between the atrophy (+) group and atrophy (-) group was observed. However, a significant relationship between condylar atrophy and loss of the lower first molars was found. And individuals in the atrophy (+) group had a tendency to lose one or both lower first molars and left them without any prosthetic restorations in the growth period of the TMJ components.
