Effect of a preventive program on dental caries and mutans streptococci in Polish schoolchildren.

The effect of a preventive program was studied in Polish schoolchildren. The study was carried out in a group of 133 children, aged 10-12 yr, divided into a test and a control group. Children in the test group were initially treated with temporary restorations and were then given oral health education and preventive treatment by a specially trained chairside assistant. The preventive treatment included prophylaxis and topical fluoride treatment and was carried out at least 10 times a year. The mean 3-yr DFS increment was 1.7 in the test and 10.9 in the control group. The salivary counts of mutans streptococci were similar in test and control group at baseline and after 1 and 2 yr. At the examination after 3 yr, a difference was established between the two groups.

How Swedish dental hygienists apply their training program in the field.

The purpose of this study was to evaluate how clinical practice by Swedish dental hygienists was related to type of dental delivery system, period of training, educational institution attended and patient category. Dental hygienists from 14 different dental hygiene schools were represented. Of these schools, 11 are still in operation. A specially designed questionnaire was posted to all dental hygienists in Sweden (n = 1857). A total of 1399 questionnaire (75.3%) were completed and returned, providing data on 15,546 dental appointments. 37.2% of the Swedish dental hygienists are presently working in private practices, 45.8% in the public dental health service and 6.2% in both. Of the patients treated by hygienists, 88.7% were adults: 99.5% in private practice and 78.4% in the public dental health service. 42.0% of all dental hygienists were trained in 1980-84. The mean treatment time per appointment in private practice was 49.7 min and 45 min in the public dental health service. Scaling, root-planning and removal of overhangs took 27 min per visit in private practice and 22 min in the public dental health service. However, there were no significant differences in methods in the two delivery systems with respect to examinations, self-care training, professional mechanical toothcleaning (PMTC), topical fluoride application, or salivary and oral microbiology tests. The adult patient categories were periodontal risk (45.1%), caries risk (9.1%) and hygiene (34.6%). In periodontal risk patients, scaling, root-planning and removal of overhangs took 28 min per appointment and 14 min in caries risk patients.

Frequent sugar intake--then and now: interpretation of the main results.

The Vipeholm Study is a unique diet-caries interventional study that has earned its place as a citation classic. One of the findings, that quantity of sugar consumed at meals in a non-sticky form had little influence on caries rate, has often been misinterpreted, as it is based on an institutional population under supervised dietary control. The other main finding, that sugary foods consumed in a sticky form at high frequency between meals are highly cariogenic, is generally accepted. Although the Vipeholm Study has been criticized on ethical grounds, relatively fewer teeth were extracted for caries than are currently extracted in an adult population. The results of two modern studies in Northumberland, UK, and Michigan, USA, on the relationship between dietary habits and caries increments in children have been compared with the Vipeholm findings. Currently the correlations between dietary habits and caries increments are low because of the low caries increments and relatively small differences in dietary patterns in non-interventional conditions. High frequency of snacking is uncommon and use of topical fluoride agents (dentifrices, rinses) is widespread. However, for the caries-susceptible person, between-meal consumption of sugary foods is still a risk factor.

Dental caries and sealant prevalences in schoolchildren in Tennessee.

This article presents findings on the prevalence of dental caries and dental sealants from the 1988 oral health survey of schoolchildren in Tennessee. The purpose of the study was to describe the prevalence of dental caries, dental sealants, and periodontal disease, as well as the need for restorative, exodontia, and periodontal treatment among schoolchildren. A multistage probability sample was designed to represent 927,000 children enrolled in grades K-12 in public and private schools across the state. Analyses of the data collected from the examination of 2,588 children aged 5-17 revealed that 55 percent were caries free in their permanent dentition and that the mean DMFS score was 2.86. For those aged 5-9, the mean dfs score was estimated to be 5.52. Only 10 percent of schoolchildren in Tennessee had dental sealants on their teeth. Comparisons of the results of this survey with those reported from earlier state surveys indicated that caries levels have declined steadily. We assumed that the reduction in caries experience observed in Tennessee is the result of widespread exposure of children to systemic and topical fluorides. Further reduction in caries experience is possible with continued fluoridation of community water supplies, in conjunction with increased utilization of pit and fissure sealants.

Practical protocols for the prevention of dental disease in community settings for people with special needs: preface.

This issue of Special Care in Dentistry presents protocols that were designed during a conference, Practical Protocols for the Prevention of Dental Disease in Community Settings for People with Special Needs, which was held at the University of the Pacific School of Dentistry on February 1, 2002. After each expert reviewed and reported on one area of the literature, which included risk assessment; chlorhexidine mouth rinses; xylitol chewing gum; topical fluoride and fluoride varnish applications; and methods to control or treat periodontal disease, practical protocols were developed. Next, a strategy of implementation and dissemination will be designed using nurses, case managers, social workers, caregivers, and others to encourage people with special needs to use these protocols. A plan will also be implemented to increase social and health care provider awareness about these interventions through professional publications and educational opportunities. The goal is to reduce dental disease in special needs populations and thereby decrease the need for difficult and costly treatment.

In vivo study on the prevention of postradiation caries.

Postradiation caries is usually prevented by the application of topical fluorides (F) at high concentrations. The aim of this study was to develop an optimal preventive program for postradiation caries by evaluating the effects of F concentration and application procedures in subjects with radiation-related xerostomia. Six ground enamel slabs were mounted on each side of the lower denture of each of 7 xerostomia patients. Four procedures were used: no F exposure (control), neutral F gel applied every 2nd day or weekly, and a daily rinse with a F mouthwash for a period of 6 weeks. The enamel slabs were analyzed at weekly intervals by scanning optical monitoring, longitudinal microradiography, and scanning electron microscopy. In addition, hardness measurements were performed on the slabs. F analyses of the enamel slabs were done prior to their insertion in the appliances and after 6 weeks of intraoral exposure. In the control experiments severe demineralization of enamel occurred within 6 weeks. Application of F gel or the use of the F mouthrinse resulted in a significant inhibition of the demineralization process. Of the procedures evaluated, F gel applied every 2nd day was the most effective in preventing the onset of postradiation caries.

Effect of radiation-induced xerostomia on human oral microflora.

A longitudinal study was performed to assess the effects of radiation-induced xerostomia on the human oral microflora. Pronounced microbial population shifts were found in each of five intraoral sites tested. Cariogenic microorganisms gained prominence at the expense of noncariogenic microorganisms in concert with the saliva shutdown. These changes occurred before the onset of clinical caries irrespective of whether or not a topical fluoride gel was used as a caries preventive.

Use of sequential analysis in clinical trials of caries prophylactic agents.

Using a sequential t test, the objectives of two 3-year experimental clinical trials were achieved more efficiently by using fewer subjects over a shorter time. The assumption of identical distributions of each batch of data analyzed was not apparent and further work to establish the robustness of sequential t tests is indicated. Identification of subjects with more consistent caries increments during the period of a trial would also help to satisfy this assumption.

Human interdental plaque-pH data and rat caries tests: results with the same substances.

Interdental plaque-pH telemetry measures, in vivo, H-ion concentration at the level of the enamel surface under an undisturbed layer of plaque. It is better suited to test non- or hypo-acidogenic products than are rat caries tests. These products can, with a very high probability, be considered non- or hypocariogenic ("safe, or friendly, for teeth"), no matter how frequently they are consumed. Plaque-pH telemetry is poorly suited for judging the effectiveness of agents directed at enamel - e.g., topical fluoride, remineralizing solutions, etc. - or agents which may have long-term effects on plaque composition. Plaque-pH telemetry is able to demonstrate the effects of different meal patterns and the form and texture of foods on oral clearance and plaque pH.

Products for prevention during orthodontics.

The potential for iatrogenic damage following fixed orthodontic treatment has been well documented for many years. Enamel decalcification and gingival inflammation are preventable if good practice is followed. Patients with gingivitis or active caries should not be considered for fixed orthodontics until the disease is controlled. Diet advice, oral hygiene, and topical fluorides are the basic elements of any preventive regime, and while they need to be individually tailored for each patient, fluoride mouthrinses should be routinely used by all patients with fixed appliances. The susceptibility of enamel adjacent to an orthodontic attachment remains a problem which future improvements in adhesive materials may help to address.

Treatment of periodontal disease in a patient with Turner's syndrome. A case report.

This case report describes a patient with Turner's syndrome receiving systemic androgen therapy who experienced marked gingival enlargement, bleeding, and discomfort. Turner's syndrome and its treatment are discussed. The literature pertaining to sex hormones and their role in affecting periodontal disease is reviewed. The patient was treated with full mouth gingivectomy and 2-week recall visits for a period of 2 months consisting of oral physiotherapy instructions, scaling, and topical fluoride application. She was then placed on 1-month recall for the next 4 months. This mode of therapy was effective in treating severe gingival hyperplasia in a patient receiving systemic androgen therapy.
