Risks and benefits of fluoride mouthrinsing.

Fluoride mouthrinses have been demonstrated in controlled clinical trials to reduce the incidence of dental caries in children by an average of 35%. This practice has been demonstrated to be a safe and effective adjunct to individual and public health preventive dental programs. The risks of fluoride mouthrinse use are primarily related to acute and chronic ingestion of fluoride, and acute ingestion of ethanol. These and other minor risks are easily controlled by adult supervision of mouthrinse use. Claims of allergic reaction or adverse behavioral reaction to food dyes in mouthrinses have not been substantiated. Recently, mouthrinses have been investigated as contributing to the risk of oral cancer, but results of retrospective studies are equivocal, especially in the light of the stronger confounding variables of alcohol consumption and tobacco use. Fluoride mouthrinses remain a safe and effective means of controlling dental decay.

Tetracycline therapy in patients with early juvenile periodontitis.

Tetracycline therapy, when used in conjunction with surgery or root planing, has been shown to be effective in controlling the progression of juvenile periodontitis. However, the ability of tetracycline alone to control the disease has not been assessed. The present study evaluated the effects of tetracycline therapy, with supragingival plaque control, on clinical attachment levels and radiographic bone height in patients with clinical and radiographic evidence of juvenile periodontitis. The four patients (mean age 15.2 +/- 0.3 yrs) each demonstrated loss of attachment of greater than or equal to 2 mm at one or more probing sites and had accompanying radiographic evidence of early localized bone loss. Following an initial clinical evaluation consisting of pocket depths, attachment levels and standardized radiographs, the patients received systemic tetracycline therapy (1 gm/day for three to six weeks) and oral hygiene instruction. At the completion of antibiotic therapy, patients received a supragingival professional prophylaxis every two weeks for three months, whereupon the initial evaluation was repeated. On comparing the initial and three-month clinical and radiographic data, there were significant decreases in clinical and radiographic measurements. For a total of 85 affected probing sites around 26 teeth, 79% decreased in pocket depth by greater than or equal to 2 mm (with no sites increasing in pocket depth) and 69% gained clinical attachment (with only one site losing attachment of 1 mm). Radiographic measurements revealed an increase in both the height and area of coronal alveolar bone. The findings indicated that six weeks of systemic tetracycline therapy combined with supragingival plaque control was effective in the initial control of early juvenile periodontitis.

Efficacy of using benzocaine for temporary relief of toothache.

The purpose of this investigation was to determine the efficacy of benzocaine for temporary relief of toothache. The agent used is available at drug counters; it contains 7.5 percent benzocaine in propylene glycol and has the form of a gel. The study was double blind. The agent and a placebo were provided by the manufacturer in an equal number of randomly numbered but otherwise unlabeled tubes. Forty-nine patients (twenty-five males and twenty-four females) with throbbing toothache pain resulting from dental caries were included in the study. The mean age was 25.6 years for patients receiving the drug and 26.7 years for patients receiving the placebo. Of the twenty-four patients who received the active agent, twenty (83 percent) were relieved of pain. The average time for onset of relief was 3.7 minutes. In the placebo group, only four patients (16 percent) were relieved of pain. When the chi-square test is used, the difference is statistically significant at the 0.01 level. No adverse reaction to the agents used was observed.

Dental caries and fluorosis among children in a rural Georgia area.

PURPOSE: This IRB-approved study compared the caries experience, fluorosis prevalence, and plaque and salivary fluoride concentrations ([F]) in middle school (MS; N = 51) and elementary school (ES; N = 144) children residing in nonfluoridated and fluoridated communities in rural Georgia. All participants were exposed to fluoridated water at school (0.5-1.2 ppm), some received that level at home, and others received home water with < 0.1 ppm F. METHODS: Subjects' parents completed a questionnaire regarding fluoride exposure. Children were examined at school by two calibrated dentists. RESULTS: No significant differences were seen in DMFS+dfs between children with or without fluoridated home water, nor for those with or without fluorosis. MS children with non-fluoridated home water had lower mean salivary [F] values than MS children with fluoridated home water. No differences were found among MS and ES children in mean plaque [F] for those with or without fluorosis. CONCLUSIONS: Home water fluoridation had little effect on the variables measured. These findings appear to be due to fluoride exposure from fluoridated dentifrices, fluoridated drinking water at school, and the fluoride "halo" effect.

The Ace Bandage approach to digit-sucking habits.

This article describes an at-home program to assist children with nocturnal digit-sucking habits. Children with such habits are candidates for this program if they wish to discontinue their habits and have no psychological contraindications for habit cessation. The program involves nightly use of an elastic bandage wrapped across the elbow. Pressure exerted by the bandage removes the digit from the mouth as the child tires and falls asleep. Careful patient selection and parent education can lead to a success rate that makes the program worth attempting prior to instituting appliance therapy.

Evaluation of the effects of orthodontic pacifiers on the primary dentitions of 24- to 59-month-old children: preliminary study.

This study was designed to compare the occlusions of 24- to 59-month-old children who used orthodontic or conventional pacifiers to the occlusions of a group of controls who had no sucking habits. Information on the habits was collected by parental questionnaires. Ninety-five children were examined for malocclusions involving overbite, overjet, canine, and molar relationships, and posterior crossbites. Users of orthodontic pacifiers had statistically significantly greater overjets, and there was a significantly higher proportion of subjects with open bite in the conventional pacifier group. There was a trend toward a greater number of subjects in the control and orthodontic pacifier group with overbites less than or equal to 50%. These differences were not clinically significant, however. There appeared to be only minor differences between the occlusions of the two pacifier groups.
