Evaluation of Guamanian dental caries preventive programs after 13 years

[Multiple aspects of the use of fluorine in public health from the viewpoint of healthcare leaders]

The article describes the perceptions of health care leaders on issues relating to the use of fluorine in public health. This is a descriptive study with a qualitative approach, using Collective Subject Discourse (DCS) as technique for processing the statements. The study population was comprised of delegates to the 13th National Health Conference; the sample was defined by convenience and consisted of 310 delegates: 56 at municipal level in Fortaleza (CE), 143 at state level (Ceará) and 111 at national level. Data were collected by semi-structured questionnaires. There were gaps in knowledge about various aspects of the use of fluorine in public health, which indicates the need to improve the level of information of society on issues relating to fluoridation. The lack of knowledge of delegates, together with the data found in the literature about the shortcomings in the monitoring and control of fluorine levels in water, are indicative of the need to reassess the role of social actors and the mechanisms used in social control.

Long-term Caries Preventive Effects of a School-Based Fluoride Mouth Rinse Program in Adulthood

The purpose of this study was to evaluate the long-term caries preventive effects of school-based fluoride mouth rinse (FMR) program in adults aged 20 years and older. 637 mothers aged from 20 to 39 years were surveyed. Clinical examinations were carried out for subjects to obtain data on dental caries prevalence when they visited local health centers to take their children for medical and dental check-ups at 1.5- or 3-years old. We also obtained information regarding the FMR program: the duration that the subjects participated between nursery school and junior high school. When analyzing data, subjects were divided into 4 groups: FMR from nursery to junior high school group (N-JH group, n=22), FMR limited to the elementary school group (El group, n=62), FMR no-experience group (n=545), and other subjects whose FMR experience is not clear (n=8). For evaluation of the FMR program effect, multiple regression analysis was used. As independent variable, the FMR program patterns were converted into dummy data, and mean DMFT was used as dependent variable. The results of multiple regression analysis between mean DMFT and FMR program patterns showed that the N-JH group and El group were negatively associated with the mean DMFT (ß=-0.20, p<0.001 for N-JH group and ß=-0.11, p=0.003 for El group).

The positive caries preventive effects of school-based FMR program from nursery school to junior high school can continue in adults aged 20 years and older.

Fluorides in dental public health programs

The use of fluorides in dental public health programs has a long history. With the availability of fluoridation and other forms of fluorides, dental caries have declined dramatically in the United States. This article reviews some of the ways fluorides are used in public health programs and discusses issues related to their effectiveness, cost, and policy.

Reviews of evidence on interventions to prevent dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries

This report presents the results of systematic reviews of effectiveness, applicability, other positive and negative effects, economic evaluations, and barriers to use of selected population-based interventions intended to prevent or control dental caries, oral and pharyngeal cancers, and sports-related craniofacial injuries. The related systematic reviews are linked by a common conceptual approach. These reviews form the basis of recommendations by the Task Force on Community Preventive Services (the Task Force) about the use of these selected interventions. The Task Force recommendations are presented in this supplement.

Incidence of caries in an infant population in Mostoles, Madrid. Evaluation of a preventive program after 7.5 years of follow-up

OBJECTIVE

To assess the efficacy and effectiveness of a dental-health programme after 7.5-years of follow-up.

DESIGN

The study follows a prospective cohort design without randomization.

POPULATION AND METHODS

The study group cohort consisted of 547 school children, 266 girls and 281 boys, the control group was composed of 237 school children, 121 girls and 116 boys. Dental examinations were carried out using WHO criteria. Preventive measures included health education, a weekly mouth rinse using sodium fluoride (NaFI) at 0.2% concentration, fissure sealants to first permanent molars and topical application of fluoride gel. The outcomes using different indices of tooth decay and socio-demographic variables were compared between study and control groups and statistical significance determined through the Mann-Whitney U-test. Logistic regression was used in the multivariate analysis.

RESULTS

There were statistically significant differences between cohorts in the indices of decay. The mean DMFT value for study group children was 1.52 and for first permanent molars (DMFM) 1.10 per child, mean DMFS was 2.09. In the control group, values were DMFT-3.07, DMFM-2.03 per child, DMFS-4.33. Logistic regression showed the preventive programme to have a significant independent effect.

CONCLUSION

The preventive programme had been effective and had a clear protective effect.

[Topical fluoride in the reduction of dental caries in adolescents in Salvador, BA, 1996]

The aim of this paper was to investigate the experience of dental caries in a population of young adults from Salvador--BA, and to associate the prevalence of caries with the utilization of topical fluoride. A cross-sectional study was carried out with a sample of 493 persons aged 12-20 years, from Salvador--BA. Data were obtained from interviews and clinical examinations and they were analyzed through backward logistic regression. The DMFT was 4.44 (SD 3.71), and, for subjects aging 12-13 years, it was 2.72 (SD 2.75). A hundred and forty adolescents reported that they had participated in oral health programs (30%), and the majority felt that they were unable to maintain their own oral health. Topical fluoride was not a significant factor in the decrease of the prevalence of caries among these young adults (RP = 0.9). There was a decline in dental caries in this group. However, it is necessary to review the surgical-restorative model of dental practice in order to achieve better results in the promotion of oral health.

[Incidence of dental caries in a child population from Mostoles: evaluation of a preventive program after 2 years]

OBJECTIVE

To know the efficacy and effectivity od dental health program after 2 years.

DESIGN

The study of prospective cohorts not aleatorized.

POPULATION AND METHODS

The exposed cohort is composed of 583 school children, 296 girls and 287 boys, the non-exposed cohort is composed of 261 school children, 132 girls and 129 boys. We carried out and odontological exploration following the criteria of the WHO the preventive measures we carried out are health education, weekly mouthrinse of NaFl at 0.2%, occlusive sealant in the first permanent molar and external application fluorine gel. We measured and compared the different indexes of tooth decay and sociodemographic variables between both cohorts, the statistic meaning has been determined through the U est of Mann Whitney.

RESULTS

We have found statistically significant differences between both cohorts in the indexes of decay in the exposed cohorts. The indexes of decay in the exposed cohort being DMFT: 0.31; DMFM (first permanent molar): 0.31; DMFS: 0.4. And in the non-exposed cohort DMFT: 0.81; DMFM: 0.81; DMFS; 1.09. Existing an epidemiological association between the preventive program and the prevention of dental decay with a relative risk of 0.24 (95% CI, 0.17-0.33) and the prevention fraction of 76.3% (95% CI, 67-83).

CONCLUSIONS

The preventive program after two years elapsed is effective and has a clear protector effect.

An evaluation of a primary preventive dental programme in non-fluoridated areas of Victoria, Australia

A primary preventive dental programme targeting adolescents living in non-fluoridated areas of Victoria, Australia was evaluated for a three-year period. The programme comprised annual placement or replacement/repair of fissure sealants combined with a weekly 0.2 per cent sodium fluoride mouthrinse and was evaluated in terms of acceptance by the providers and the community to which it was directed. Acceptance was measured using accessibility, availability, continuity, quality of care, role responsibility, provider and consumer satisfaction, and cost-effectiveness. In general, the programme was considered to represent an acceptable model for future preventive interventions, although there were areas of its design that were found to require improvement. In particular, deficiencies in the manner in which the fluoride mouthrinsing component was delivered indicate that further investigation would be required before a recommendation to adopt its use could be made.
