    Notes: The interrelationships of a modified Tooth Cervical Height Index (Davies et al. 1969) and tooth irregularity were evaluated on the posterior teeth of 90 skulls. Two readings were made for tooth displacement, rotation, and the Tooth Cervical Height Index for each maxillary and mandibular first bicuspid, second bicuspid, and first molar. The average Tooth Cervical Height Indices of the 6 posterior teeth ranged from 3·34 mm. for the mandibular first bicuspid to 1·63 mm. for the maxillary second bicuspid. Within each skull a definite relationship existed between the bone heights of the various teeth, viz., where a high recording was made on any one tooth there was tendency for high scoring on the remaining teeth of that skull. Tooth irregularity did not appear to have any association with the alveolar bone height.

    Notes: Abstract Two studies are reported. Each was double-blind in which Spiramycin was compared to Erythromycin and a placebo, to determine the value of Spiramycin as a therapeutic agent in the control of periodontal disease. In Study 1, 48 adults with varying degrees of periodontal disease were randomly assigned to treatment and control groups. Assessments of gingival index, plaque height, pocket depth, crevicular fluid volume and wet plaque weight were made. During this 4-week clinical trial, the patients maintained their usual oral hygiene. The medication was administered systemically for 5 days, starting at the conclusion of week 2.Spiramycin significantly reduced the scores for the five parameters recorded. When comparisons were made, the greatest recorded effect with Spiramycin treatment was found in patients with advanced periodontal disease. The indication of this trend favouring Spiramycin led to art extension of this clinical trial involving only patients with advanced periodontal lesions.This second study comprised 54 adults. The same parameters, were measured over the same time period as in Study 1. Spiramycin again was responsible for the greatest reduction in the recorded scores. For example, average pocket depth was decreased by approximately 30%, whereas Erythromycin produced a reduction of 15%. It would appear that Spiramycin is of definite benefit in the management of periodontal disease, especially in the more advanced cases.

    Notes: Powdered, sterilized zinc polycarboxylate was implanted subcutaneously in 56 young hamsters and 54 mice, using equal numbers of each sex, with 24 sham operated hamsters and 26 mice as controls. The hamsters were sacrificed after 15 months and the mice after 12. Implant material was recovered from one of 42 surviving mice and from 16 of 43 surviving hamsters. Benign adenomas of the gut, thyroid, sebaceous glands and ovary were found in 3 experimental mice and in one control. Benign adrenal adenomas were found in 3 experimental hamsters and in one control. One control hamster developed a rhabdomyosarcoma in a limb. One experimental hamster developed a leiomyosarcoma in close relation to an implant.
