The primary purpose of this study was to determine the amount of tooth staining produced by an alexidine mouthrinse. One hundred and eighty subjects rinsed twice daily for 1 month with either 15 ml of alexidine (0.035%) or a placebo solution. Prior to the study, the subjects were classified according to their smoking, coffee and tea drinking habits and these factors were subsequently considered in the analysis of the stain scores. Additionally, the effects on staining of a prior prophylaxis and the use of a fluoridated toothpaste during the study were determined. Upon termination of the study, subjects utilizing the active mouthrinse manifested a greater degree of staining than placebo users. The amount and intensity of the stain due to alexidine were not influenced (increased) by smoking, tea or coffee drinking habits. A prior prophylaxis did not reduce the staining propensity of alexidine users. The method of scoring developed can be used to assess the degree of tooth staining induced by antiplaque agents.

The effect of an alexidine mouthwash on plaque and gingivitis.

A clinical study was conducted on the effects of an alexidine or placebo oral rinse on plaque and gingivitis. Forty-two male subjects rinsed for 54 days while continuing toothbrushing. This was followed by 4 days of mouthrinsing only. The alexidine mouthrinse significantly reduced the plaque index when used in conjunction with toothbrushing and also when brushing was discontinued. The gingivitis results were inconclusive.

Reflections on the three-year program.

Dental education has twice altered curriculum length from four- to three-year programs. The first switch from four to three years came during World War II to meet the need for additional dentists, but schools rapidly returned to four-year programs after the war. During the early 1970s, 14 dental schools converted to three-year programs; however, by 1976 several of these schools had returned to the four-year programs. At the New Jersey Dental School, one of the first schools to adopt a three-year program in 1970, a return to a four-year program in 1977 was the result of poor acceptance of the program by the faculty, a lack of flexibility in the schedule, and an undiminishing negative attitude by the profession toward the graduates. The experience derived from the three-year curriculum has reenforced the need for designing variable length programs, because a significant number of students can successfully complete the traditional program in three years.
