Four-year incidence and predictors of coronal caries in south Brazilian elderly

Prevalence, and Risk Indicators of Coronal and Root Caries in Mexican Older Adults in Nursing Homes

Background

Several factors are associated with coronal and root caries in older persons. The purpose of this study was to determine the experience, prevalence, and risk indicators (socioeconomic, sociodemographic, and dental variables) of coronal and root caries in older persons residing in nursing homes in Mexico.

Methods

A cross-sectional study was carried out in 227 dentate participants with natural teeth. Convenience sample, where all dentate residents were invited to participate. The dependent variables were coronal caries and root caries, which were determined through an oral clinical examination. The independent variables were sociodemographic factors, location, type of center, surfaces free of dental biofilm and calculus, surfaces with recession, retainers in contact with surfaces with recession, xerostomia, smoking, and the previous use of dental services. The binary logistic regression model was used in the analysis.

Results

The mean age of the participants in this study was 77.7±8.8 years, and 69.2% were women. Moreover, 71.8% live in long-term care facilities, and 48.0% live in Mexico City. The prevalence of coronal and root caries was found to be 67.8% and 50.7%, respectively. Being male and living in Mexico City were risk indicators for coronal caries, and with a 1% increase in surfaces with no biofilm, the risk decreased by 2%. Being widowed, having government or no social security, denture retainers, and coronal caries were risk indicators for root caries, while the utilization of dental services indicated lower risk.

Conclusion

Several variables that differ in nature were found to be risk indicators for coronal and root caries. Coronal caries increases the risk of root caries. Prevention should be aimed at identifying persons at higher risk, and dental care should be improved for persons living in long-term care institutions.

Salutogenic factors for oral health among older people: an integrative review connecting the theoretical frameworks of Antonovsky and Lalonde

OBJECTIVE

The aim of this integrative review was to describe salutogenic factors associated with oral health outcomes in older people, from the theoretical perspectives of Antonovsky and Lalonde.

MATERIAL AND METHODS

This study was based on a primary selection of 10,016 articles. To organize reported salutogenic factors, the Lalonde health field concept and Antonovsky's salutogenic theory were cross tabulated.

RESULTS

The final analysis was based on 58 studies. The following oral health outcome variables were reported: remaining teeth, caries, periodontal disease, oral function and oral health related quality of life (OHRQoL). We could identify 77 salutogenic factors for oral health and OHRQoL. Salutogenic factors were identified primarily within the fields of Human Biology (such as 'higher saliva flow', 'BMI < 30 kg/m²' and 'higher cognitive ability at age 11'), Lifestyle (such as 'higher education level', 'social network diversity' and 'optimal oral health behaviour') and Environment (such as 'lower income inequality', 'public water fluoridation' and 'higher neighbourhood education level'). In the age group 60 years and over, there was a lack of studies with specific reference to salutogenic factors.

CONCLUSIONS

The results provide an overview of salutogenic factors for oral health from two theoretical perspectives. The method allowed concomitant disclosure of both theoretical perspectives and examination of their congruence. Further hypothesis-driven research is needed to understand how elderly people can best maintain good oral health.
