Periapical cemental dysplasia with multiple lesions.
3 cases of periapical cemental dysplasia with multiple lesions in both maxilla and mandible are reported. All 3 patients are middle-aged females with an average age of 47 years; histological examination of excised tissue revealed that the lesions were composed of fibrous connective tissue and cementum-like hard tissue. The location of the teeth affected were mainly in the premolar-molar regions. A subsequent literature survey of previously described Japanese cases of periapical cemental dysplasia disclosed a similar distribution pattern for the location of PCD lesions. This evidence indicates that the occurrence sites of lesions of periapical cemental dysplasia is predominantly in premolar-molar regions in Japan, contrary to the location of PCD in other ethnic groups.
