Associations between tooth loss, prostheses and self-reported oral health, general health, socioeconomic position and satisfaction with life

Exploring the relationship between oral health and multiple health conditions: An outcome-wide approach

PURPOSE

A growing body of evidence suggests that oral health is associated with a wide range of health outcomes; however, opinions tend to vary because of inconsistent findings. This study aimed to simultaneously examine the association between oral health status and multiple health and well-being indicators using outcome-wide epidemiology.

METHODS

Data were obtained from the Japan Gerontological Evaluation Study. Oral health status was categorized as: ≥20 teeth, 10-19 teeth with dental prosthesis, 0-9 teeth with prosthesis, 10-19 teeth without prosthesis, and 0-9 teeth without prosthesis. We examined the associations between oral health status in 2013 and 35 health and well-being outcomes in 2019, including physical/cognitive health, psychological distress, subjective health, social well-being, prosocial/altruistic behaviors, and health behaviors, using two databases (n=32,827 and 15,905).

RESULTS

Compared to individuals with ≥20 teeth, those with <20 teeth had a 10-33% higher risk of mortality and a 6-14% higher risk of functional disability six years later. Additionally, individuals with fewer than 20 teeth tended to go out less frequently and eat fewer vegetables and fruits. Furthermore, individuals with 0-9 teeth without a prosthesis were more likely to have severe functional disability (risk ratio (RR):1.17, 95% confidence interval (CI):1.05-1.31), engage in fewer intellectual activities (standardized difference: 0.17, 95% CI: 0.10-0.24), and feel more hopeless (RR: 1.21, 95% CI: 1.04-1.41).

CONCLUSIONS

The prevention of tooth loss and prosthodontic treatment may be associated with reduced mortality and functional disability, as well as maintenance of intellectual ability, frequency of going out, and improvements in dietary lifestyle.

Association between cognitive rumination and periodontal disease, tooth loss and oral health-related quality of life in a rural Southern Brazil population

OBJECTIVES

Rumination is a maladaptive emotion regulation strategy. It has been associated with several psychological disorders and physical problems. This cross-sectional study aimed to evaluate whether cognitive rumination is associated with periodontal disease (PD), tooth loss (TL), and oral health-related quality of life (OHRQoL).

MATERIALS AND METHODS

A population-based sample from a rural area in southern Brazil was evaluated. Calibrated examiners carried out a complete periodontal examination at six sites-per-tooth. Rumination and Reflection (RRQ) and Oral Health Impact Profile (OHIP-14) questionnaires were administered. Regression modeling was used to assess the prevalence ratio (PR) between rumination and PD and to estimate the rate ratio (RR) between rumination and TL and rumination and OHIP.

RESULTS

Severe periodontitis prevalence of 33% was observed in the sample. In the Poisson-adjusted model (n = 587), individuals who ruminate more have 27% more periodontal disease (PR: 1.27, 95%CI:1.02 - 1.60). Regarding TL and OHIP, negative binomial regression (n = 672) showed an association with rumination, but it was not significant (RR 1.14, 95%CI 0.99 - 1.31) and (RR 1.20, 95%CI 0.98 - 1.48), respectively.

CONCLUSIONS

Cognitive rumination was independently associated with periodontal disease in individuals living in a rural area. Borderline non-significant estimates were observed regarding TL and OHRQoL. More research using different populations and focusing on individual's responses to psychological stress may confirm these results.

CLINICAL RELEVANCE

Emotional regulation is crucial to deal with stress, anxiety, and depression. Since psychopathologies are among the most prevalent diseases in the world, it is critical to understand the role of these issues in dental outcomes.

Psychosocial aspects associated with self-reported oral health in Brazilians older adults

OBJECTIVES

Oral health conditions can be determined by a series of factors that include psychosocial aspects. Therefore, this study aimed to investigate the association between psychosocial aspects and self-reported oral health in Brazilian older adults.

METHODS

The Brazilian Longitudinal Study of Ageing (ELSI-Brazil) baseline data was analysed to develop this cross-sectional study. The outcome was self-reported oral health, and the psychosocial aspects included neighbourhood trust, life satisfaction and depressive symptoms. The associations were determined through Poisson regression models, controlling for socioeconomic, demographic and behavioural characteristics.

RESULTS

A total of 9365 individuals with aged 50 years or over were included in this study. Individuals with good life satisfaction had 16% (PR: 0.84; 95% CI: 0.78-0.90) lower prevalence of having poor self-reported oral health. Individuals who have depressive symptoms and do not trust in the neighbourhood presented 17% (PR: 1.17; 95% CI: 1.09-1.25) and 12% (PR: 1.12; 95% CI: 1.04-1.21) higher prevalence of poor self-report oral health compared to those who did not show depressive symptoms and trust the neighbourhood.

CONCLUSION

Our findings suggest that positive psychosocial aspects are moderately associated with better self-reported oral health. Therefore, we suggest that psychological health and social interaction should be present in public health policy actions.

Can patients detect peri‑implant mucosal inflammation? Results from a multicentre randomized trial

PURPOSE

The objective of this study was to compare patient-reported outcomes (PROs) of peri‑implant soft tissue inflammation and aesthetics around single-tooth implants in the anterior maxillary region with three different implant-abutment interface designs.

METHODS

Participants were randomized to one of three different types of implant-abutment interface designs [Conical (CI), flat-to-flat (FI), and Platform Switched (PS)]. Implants and provisional crowns with prefabricated titanium abutments were placed 5 months following extraction and/or ridge augmentation. Permanent ceramic crowns with zirconia abutments were placed after 12 weeks. To assess PROs, appearance and inflammation questionnaires were completed from provisional crown placement to the 3-year follow-up.

RESULTS

Tooth appearance at the 3-year follow-up revealed a difference amongst CI, FI and PS implants (p=0.049; Kruskal-Wallis test). PS was rated better than FI (p=0.047) at 1 year for appearance of soft-tissue and satisfaction with colour. There were no differences for self-consciousness, smile and pain/discomfort while eating/hard food items.

CONCLUSIONS

Although participants tended to rate the health of mucosa around PS implants as slighty better than the other two implant systems, the differences were minimal and inconsistent. Thus, patient satisfaction in terms self-perceived gingival health and esthetics was high for all 3 systems tested, suggesting that patients are unable to detect mucosal inflammation.

CLINICAL SIGNIFICANCE

Patients find it difficult to perceive mucosal inflammation; hence, it is recommended that patients attend implant follow-up visits, even if they do not perceive inflammation. The study suggests that there is a relationship between the PROs and the clinical outcomes of tested implants.

Contextual and individual factors associated with self-reported tooth loss among adults and elderly residents in rural riverside areas: A cross-sectional household-based survey

BACKGROUND

Tooth loss is an oral health condition with high prevalence and negative impact on quality of life. It is the result of the history of oral diseases and their treatment as well as provision of dental care and access to dental services. Socioeconomic characteristics are determinants of tooth loss and living in rural areas is also a risk factor for its incidence.

OBJECTIVE

To identify contextual and individual factors associated with self-reported tooth loss among adults and elderly people living in rural riverside areas.

METHODS

A cross-sectional household-based survey was conducted in 2019 with rural riverside communities on the left bank of the Rio Negro River, Manaus, Amazonas. These communities are covered by a fluvial health team and two riverside health teams. Interviews were conducted in a representative random sample of dwellers aged ≥ 18 years, using electronic forms to obtain information on oral health conditions, demographic and socioeconomic characteristics, and use of and access to health services. The outcome was self-reported tooth loss. After the descriptive analysis of the data, a multilevel Poisson regression analysis was performed to estimate the prevalence ratio for the outcome. Variables with p-value ≤0.20 in the bivariate analyses were included in the multiple analysis considering the hierarchy between individual and contextual variables in the multilevel model. Variables with p-value ≤0.10 were kept in the final model and the significance level adopted was 0.05.

RESULTS

603 individuals from 357 households were assessed (mean age 44.1 years). The average number of missing teeth was 11.2 (±11.6); 27.4% of individuals had lost more than 20 teeth (non-functional dentition) and 12.1% were completely edentulous. Contextual characteristic of primary healthcare offered was associated with the outcome. The tooth loss was lower in territories covered by riverside health teams. At individual level, tooth loss was greater in older individuals who had experienced dental pain over the past six months and whose sugar consumption was high. Black or brown individuals, individuals whose household income was higher, those who were on the Bolsa Família cash transfer program, those who consulted a dentist over the past year, and those who reported satisfaction with their teeth/oral health reported less tooth loss.

CONCLUSION

Tooth loss was associated with contextual territorial factors related to the healthcare service and individual demographic, behavioral, socioeconomic, and service-related characteristics as well as self-perceived oral health conditions. The findings suggest that actions focused on the oral health of these populations involve not only changes in the healthcare service organization, but also intersectoral policies that contribute to reducing social inequalities.

Biobanking in dentistry: A review

Biobanks are not-for-profit services for the collection, processing, storage and distribution of biological samples and data for research and diagnostic purposes. In dentistry, biological materials and data obtained from questionnaires investigating oral conditions can be stored and used for large-scale studies on oral and systemic diseases. To give some examples: gene expression microarrays obtained on biobanked specimens were used in the identification of genetic alterations in oral cancer; efforts to identify genetic mechanisms behind dental caries have been based on an integrative analysis of transcriptome-wide associations and messenger RNA expression. One of the largest studies on facial pain was conducted using Biobank data. Cryopreservation of dental pulp stem cells is a common practice in tooth biobanks. With the exception of teeth and pulp, also leftover oral soft and hard tissues may represent a source of healthy samples that has rarely been exploited as yet. While biobanks are increasingly attracting the attention of the scientific community and becoming economically sustainable, a systematic approach to this resource in dentistry seems to be lacking. This review illustrates the applications of biobanking in dentistry, describing biobanked pathological and healthy samples and data, and discussing future developments.

Development of a one-item version of the Orofacial Esthetic Scale

OBJECTIVES

Orofacial appearance is increasingly recognized as an important dental patient-reported outcome making instrument development and refinement efforts to measure the outcome better necessary. The aim of this study was to derive a one-item version of the Orofacial Esthetic Scale (OES).

MATERIALS AND METHODS

OES data were collected from a consecutive sample of a total of 2113 adult English- or Spanish-speaking dental patients from HealthPartners dental clinic in Minnesota. Participants with missing data were excluded and analysis were performed using data from 2012 participants. Orofacial appearance was assessed with the English and the Spanish language version of the OES. Linear regression analysis was performed, with the OES item 8 ("Overall, how do you feel about the appearance of your face, your mouth, and your teeth?") as the predictor variable and the OES summary score as the criterion variable, to calculate the adjusted coefficients of determination (R²).

RESULTS

The value of adjusted R² was 0.83, indicating that the OES item 8 score explained about 83% of the variance of the OES summary score. The difference in R² scores between the two language groups was negligible.

CONCLUSION

The OES item 8 can be used for the one-item OES (OES-1). It is a psychometrically sound instrument for measuring orofacial appearance.

CLINICAL RELEVANCE

Due to its easy application and sufficient psychometric properties, the OES-1 can be used effectively as an alternative to longer OES instruments in all areas of dental practice and research.
