A longitudinal study of gingivitis and puberty

Abstract: A longitudinal study of 127 children between the ages of 11 and 17 years revealed a high initial prevalence of gingivitis that tended to decline slightly with age. The distribution of the ages of the children when experiencing their observed maximum amount of gingivitis was consistent with the hypothesis that there is a relationship between puberty and gingivitis. There was also evidence that at the time of the peak gingivitis experience the gingival tissues were exhibiting a heightened response to irritation.

Inhibition of experimental caries by plaque prevention. The effect of chlorhexidine mouthrinses.

Abstract: – The purpose of this study was to test the hypothesis that a frequent intake of sucrose does not produce caries if the teeth are regularly treated with an antibacterial agent. Twenty-four students with clean teeth and normal gingivae were assigned to one of the following three groups: (1) eight individuals ceased all active oral hygiene measures and rinsed 9 times daily with 50% sucrose, (2) eight students refrained from all active oral hygiene procedures, rinsed 9 times daily with sucrose and twice daily with 10 ml 0.2% chlorhexidine gluconate, (3) the third group consisted of two subgroups each comprising 4 students. One subgroup ceased all oral hygiene procedures and rinsed twice daily with 0.2% chlorhexidine gluconate. The other was instructed to practice meticulous tooth brushing twice daily. The experiment lasted for 22 days. The group who rinsed with sucrose showed heavy plaque accumulation, those who rinsed with sucrose + chlorhexidine showed a drastic reduction in the formation of plaque. In the subgroup rinsing with chlorhexidine only and in that performing good oral hygiene, plaque was non-existent. The gingival state essentially paralleled the plaque formation. The sucrose group showed a definite increase in Caries Index. No significant changes occurred in the group rinsing with sucrose + chlorhexidine, with chlorhexidine only, or in the group performing good oral hygiene. It is concluded that prevention of plaque formation inhibits the development of gingivitis and dental caries, even with frequent rinses of sucrose.

Relationship between malalignment of the teeth and periodontal disease.

Abstract: – The occurrence and degree of displacement and rotation was recorded in the 4,316 fully erupted teeth of 154 Army recruits aged 19–22 years. Of the different teeth, it was the maxillary laterals and the mandibular second premolars which were most often found to be malaligned. In the maxillary anterior tooth areas, which had been fairly well brushed by the subjects, both the degree of oral cleanliness and the extent of periodontal disease were worse around the malaligned than around the aligned teeth. In the premolar areas the difference was less marked and it became non-existent in the molar regions. The results indicated that malalignment of the teeth, as such, does not enhance periodontal breakdown but that it decreases the effect of average oral hygiene measures. Exceptionally good oral hygiene measures or, on the other hand, no oral hygiene measures at all, are thus less likely to reveal an association between malalignment and periodontal disease.

Oral care of patients irradiated for cancer of the head and neck.

Abstract: Close cooperation between physician, dentist, and patient is essential when considering oral care of patients irradiated for cancer of the head and neck. Frequent dental examination, topical fluoride application, and meticulous oral hygiene at home can prevent loss of the teeth. Xerostomia, following radiation therapy, seems to be the major factor in decay development. Silver amalgam is at present the most practical material in restoring the cervical dental lesions seen most often after irradiation. Dental prostheses require frequent checks to eliminate irradiation and pressure which may precipitate osteoradionecrosis. Extractions after radiation therapy can be performed with a reasonable degree of safety, if done with little trauma and under antibiotic coverage. A prophylactic approach to the problem of radiation decay and periodontal breakdown keeps oral complications within controllable limits.

A fluorescent plaque disclosing agent.

Abstract: The purpose of this study was to evaluate the Plak-Lite® disclosing system. Four dental students with clean teeth and healthy gingiva abolished oral hygiene for 10 days. Plaque development was assessed using the Plaque Index system and by calculating the area of Plak-Lite® fluorescence on standardized photgraphs of anterior teeth. The experiment was repeated without utilization of disclosisng solutions. The study has demonstrated that the Plak-Lite® system reveals bacterial plaque on the teeth, tongue and gingiva. Plaque free teeth do not fluoresce. Plak-Lite® was well accepted by the patients. The agent is not bactericidal and may be used in longitudinal studies of plaque growth.

Epidemiologic Studies of Caries-Free and Caries-Active Students: II. Diet, Dental Plaque, and Oral Hygiene

Abstract: Diet, extent of dental plaque, and oral hygiene scores for caries-free and caries-active students were significantly different. Results of this study suggest that these three parameters are contributing supplementary factors to the development of dental caries in the caries-active group. An experimental dietary questionnaire method used in this study may be used by dentists to identify children with a caries-conducive diet and to prescribe treatment accordingly.

Improvement in oral hygiene as a function of applied principles of behavioral modification.

Abstract: Dr. Stacey has planned and reported a novel investigation of technics for motivating improved oral hygiene in children.

Fluoride content of dental plaque after brushing with a fluoride dentifrice

Abstract: – From 4 dental students practicing conventional oral hygiene, samples of plaque were taken at weekly intervals. Before the introduction of a sodium fluoride containing dentifrice, the fluoride concentration of the plaque was 24–45 ppm (dried weight basis) and afterwards it was 42–229 ppm.

Plaque control for handicapped children

Abstract: Because home care is essential to an effective plaque control program, oral hygiene for handicapped children is dependent on the quality of care given by parents or guardians. Parents can be taught various techniques to enable them to care for their children’s oral health more easily and completely.

Awareness of the presence of dental caries and gingival inflammation in young adult males.

Abstract: A comparison was made of the caries prevalence and gingival conditions of 167 Army recruits as assessed by themselves and as determined through a detailed clinical and radiographic study. the results showed that the subjects were surprisingly well aware of the amount of caries in their teeth while their knowledge of gingivitis and its symptoms was close to nil. Clinically gingivitis and gingival bleeding was found in all subjects. However, only 2 % of the examinees were aware of their gingivitis in spite of the fact that as many as 46 % had noticed gingival bleeding. In an earlier study the toothbrushing frequency of the same subjects was found to be low. It was now suggested that an improved general knowledge of gingivitis and its symptoms, of the close correlation between poor oral hygiene and gingival inflammation, and of the reversible character of incipient gingivitis might result in an essential improvement in the general standard of oral hygiene. This, in turn, would also decrease the caries suscep...

Compositions for cleaning teeth and oral cavity

Abstract: Compositions for cleaning teeth and oral cavity which contains as an active ingredient an effective amount of invertase. The present cleaning composition is especially effective in reduction of dental plaque formation and prevention of dental caries.

Studies in Dental Health Education: I. Effect of Antibiotic Prophylaxis on the Oral Hygiene and Periodontal Health of Young Men

Abstract: The effect of mass, routine penicillin and sulfadiazine prophylaxis on the oral hygiene and periodontal health of young men was assessed. No differences referrable to the drug regime could be discerned between experimental and control groups.
