The coronally positioned flap alone or with EMD is an effective procedure to cover localized gingival recessions. The addition of EMD significantly improves the amount of root coverage.
Dental plaque growth was observed among 180 teenage boys during a 28-day period following prophylaxis. During this period, subjects brushed their teeth under supervision for 2 minutes daily. Plaque levels were measured immediately after brushing and 24 hours after brushing. Both levels increased rapidly during the first 14 days and appeared to be leveled off at 28 days. Less than half of the plaque was removed with one brushing per day leaving about 60% after brushing to promote rapid regrowth. Regrowth rate after brushing on the 28th day was 0.032 plaque units per hour over a 24-hour period. The regrowth rate for the group brushing with dentifrice was 27% lower than for the group brushing without a dentifrice.
Within the limits of this study it is concluded that (1) periodontal health can be maintained with proper preventive maintenance irrespective of the genotype present, (2) the mean response to mucogingival surgery to cover localized gingival recessions is similar irrespective of the IL-1 periodontal genotype, however, full coverage is achieved more frequently in genotype negative subjects.
A commercially available antimicrobial mouthrinse was evaluated among students in Mexican boarding schools. The application was made daily for 3 months under the direct supervision of the project personnel. The observations indicated that the use of this mouthrinse decreased gingivitis substantially in comparison to the use of a control rinse which consisted of flavored water. It is concluded that this mouthwash, containing the known antimicrobial agents cetylpyridinium chloride and domiphen bromide, can be of clinical benefit if conscientiously applied as an adjunct in an oral hygiene regimen of regular toothbrushing with a dentifrice.
A dental caries survey of 2,445 Mexican children, 6 to 15 years of age, was conducted in an industrial city. The children were divided into three socioeconomic groups. The pattern of the caries attack rate conformed to all caries surveys. However, the DMFT and DMFS scores increased as the socioeconomic levels increased. The higher socioeconomic groups presented evidence of more dental care than the low group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
