Twenty-five years after treatment with thorium X (Ra 224), we found unusual, multifocal dental resorptions in four patients. The results of gamma-spectrographic, auto-radiographic and histological examinations suggest that Ra 224 caused such changes.

A clinical and radiologic study of early and late manifestations in tuberculoid, dimorphous, and lepromatous leprosy was undertaken in order to determine characteristics, occurrence, and incidence of facial and oral lesions. Dermal, mucosal, neural, skeletal, and dental changes were correlated with the duration of leprosy, duration of treatment, and age of the patient.
Multiple external-internal resorptions are infrequent and are related to a variety of etiological factors. Thorium X (224Ra) is believed to cause the dental resorptive changes observed in 2 patients who had received a series of injections each containing 8 to 70 muCi of 224Ra 25 years previously.
Thirty patients with lepromatous leprosy of long duration were examined for gingival and periodontal changes. All patients presented with chronic gingivitis and periodontitis of an unspecific type. Etiologic factors affecting the development of gingival and periodontal changes in this disease are: lack of oral hygiene with severe plaque and calculus formation due to the inability of the patients to perform oral hygiene, mouth breathing, specific granulomatous infiltrations, and a possible specific drug action. Specific changes in form of 'facies leprosa' are not pathognomonic of lepromatous leprosy but may be found in 20% of the cases among Thai and Chinese patients. Occurrence and pathogenesis of 'facies leprosa' is described.

Dens evaginatus in the Thai had not been described previously. The incidence of this abnormality was found to be 1.01 per cent. The male to female ratio was 1:1.83, a figure which is comparable to findings among the Chinese, since the two groups are closely related. The evagination was observed in fifty-one patients, with 133 premolars and one molar being affected. Thirty-six premolar showed periapical pathosis which was classified into clinical and radiographic features. The frequency of affection of the different premolars was described, together with the histologic appearances of the anomaly. Pathogenesis of dens evaginatus in the Thai seems to be uniform, determined by racial and genetic factors.

It is reported on a therapeutical method of smoking dental worms out of carious lesions that was observed in Chaingmai, Thailand. Historical concepts regarding the development of caries and methods for removing dental worms compared with the observations described reveal identical ideas and methods.
