A clinical and radiographic study of 104 cases with cementoma

Abstract

A study was made of a series of 104 cases with cementoma. This investigation of cementoma revealed the following features: 1. In 73% of periapical cemental dysplasia and benign cementoblastoma, and 80% of cementifying fibroma occurred in female. 2. 40 % of periapical cemental dysplasia occurred in the fifth decades, and 73 % of benign cementoblastoma during the second and third decades, while there was no age predilection in the cementifying fibroma. 3. 63 % of periapical cemental dysplasia occurred in the mandibular anterior region. 91 % of benign cementoblastoma and 80 % of cementifying fibroma occurred in the mandibular premolar and/or molar region. 4. There were no cases complaining of the associated clinical signs and subjective symptoms in the periapical cemental dysplasia, however the patients complained of a pain in 36 % of benign cementoblastoma and 40 % of cementifying fibroma. 5. There were no cases expanding the cortical plates in the periapical cemental dysplasia, however 73 % of benign cementoblastoma and all of the 5 cases of cementifying fibroma showed the expansion of cortical plates. 6. Several radiographic features of the periapical cemental dysplasia were shown as follows: a. 29 % of the cases had multiple lesions. b. 53 % of the cases were in the mature stage. c. During the osteolytic stage, the alveolar lamina dura was lost in 89 % of the cases.
