Tooth loss in maintenance patients in a private periodontal practice.

A group of 162 maintenance patients, previously studied for compliance to suggested maintenance schedules, were surveyed for tooth loss over a 5-year period. The group was divided into those who complied to suggested maintenance schedules and those whose compliance was erratic. It was found that none of the patients who had complied to suggested maintenance schedules lost any teeth. In the erratic group, where all tooth loss occurred, it was found that the more often a patient presented for maintenance, the less likely he was to lose teeth. These findings are discussed in relation to current studies on efficacy of various therapies for periodontal diseases.

Repeat ectopic pregnancy: a 16-year clinical survey.

This study includes 347 cases of ectopic pregnancy. A comparison was made between patients having one ectopic pregnancy, those having a repeat ectopic pregnancy, and those whose first pregnancy was an ectopic one. Emphasis was placed on obstetric history and the reproductive future of these patients. Obstetric performance was poor for all groups of patients studied. In the patient whose first pregnancy was ectopic, total reproductive performance was complicated by an increased risk of a repeat ectopic pregnancy. The incidence of repeat ectopic pregnancy was 11.2%. The average interval between ectopic pregnancies was 2.83 years; 80% of the repeat pregnancies occurred within 4 years of the first ectopic episode. Obstetric outcome was likely to be poor after the second ectopic pregnancy.
