Association between oral health-related quality of life and symptoms of temporomandibular disorder among older adults: A cross-sectional study

OBJECTIVE

Evaluate the association between oral health-related quality of life (OHRQoL) and self-reported symptoms of TMD.

METHODS

Representative samples of older adults (≥60 years) were included (n = 569). Both TMD symptoms and OHRQoL were assessed by Fonseca Anamnestic Index (FAI) and Oral Health Impact Profile-14 (OHIP-14), respectively. Prevalence (those answering "frequently" or "always" in at least one question), severity (total means scores), and extent (number of questions answered as "frequently" or "always") of OHRQoL were estimated.

RESULTS

Overall, 33.4% and 9.5% had mild or moderate/severe TMD symptoms. Those with any symptom of TMD had a prevalence ratio (PR) 38% higher for the worst OHRQoL (95% confidence interval [95%CI]:1.04-1.82) compared to those without TMD symptoms. Worst OHRQoL were observed for those with mild (PR:1.35; 95%CI:1.01-1.81) and moderate/severe TMD (PR:1.53; 95%CI:1.04-2.26). Similar results were detected in the severity and extent of OHRQoL.

CONCLUSION

Severity TMD was associated with worse ORHQoL.

Association between salivary flow and dental caries in institutionalized adolescents: Cross-sectional study

Background

Brazil has a larger number of adolescent offenders, but studies evaluating their oral health are still limited.

Objective

Assess the association between salivary flow and caries experience in youngsters deprived of liberty.

Methodology

Sixty-eight male adolescents in conflict with the law, aged between 15 and 19 years, from a Socio-Educational Assistance Center in Brazil participated in the present study. They answered a structured questionnaire, and oral examination was performed by the Decayed, Missing, and Filled Teeth (DMFT) index. The salivary flow rate was obtained using the mechanically stimulated total saliva method. Adjusted Poisson regression was used for the association with total DMFT and its decayed component, using the salivary flow (continuous fashion) or the hyposalivation (≤1 ml/min) as independent variables.

Results

Participants were divided into two groups, those who did not have any decayed teeth at the moment of the examination (n = 39) and those who had at least one decayed tooth (n = 29). Moreover, two groups were formed based on the DMFT: those who had DMFT = 0 (n = 20) and those who had DMFT≥1 (n = 48). In the multivariate analysis, hyposalivation was associated with DMFT≥1 (p = 0.048), but when the salivary flow was included, no significant association with DMFT index was identified (p = 0.178). Conversely, the presence of at least one decayed tooth was significantly associated with the salivary flow (p = 0.004), but not with hyposalivation (p = 0.091).

Conclusions

Institutionalized adolescents who present hyposalivation or low salivary flow are associated with DMFT≥1 index or presence of at least one decayed tooth, respectively.

Prevalence of Edentulism and Associated Factors in Older Adults: a Cross-Sectional Study

AbstractStudies assessing edentulism in a population-base sample are scarce. To evaluate the prevalence of edentulism and associated factors among older adults. A cross-sectional home-based observational study with a probabilistic sample per cluster was conducted with 282 older adults aged ≥60 years in the city of Veranópolis/Brazil. Clinical oral health examination and a structured questionnaire was administered. The main outcome was edentulism. Uni- and multivariate analyses were performed, using Poisson regression with robust variance. The prevalence of edentulism was 48.6% (n=137). In the final multivariate model, age, level of education and access to the dentist remained associated with edentulism. With each one-year increase in age, there is a 2.7% increase in the Prevalence Ratio (PR) of being edentulous (PR: 1.027; 95% confidence interval [95%CI]:1.015–1.039). Older adults with medium/high level of education had 39.4% lower PR of being edentulous (PR: 0.606; 95%CI:0.382–0.961). Older adults without access to the dentist had 78% (p<0.001) higher PR of being edentulous when compared to those that visited the dentist in the last 12 months. The prevalence of edentulism in the older adults was high and was associated with sociodemographic and access to oral care variables. Keywords: Aged. Tooth Loss. Risk Factors. Epidemiology. ResumoEstudo que avaliem edentulismo em uma amostra de base populacional são escassos. Avaliar a prevalência de edentulismo e fatores associados em idosos. Um estudo transversal de base populacional com amostra probabilística per cluster foi conduzida com 282 idosos, com idade ≥60 anos, na cidade de Veranópolis/Brasil. Exames orais e questionário estruturados foram realizados. O principal desfecho foi edentulismo. Análise uni- e multivariada foram realizadas, utilizando regressão de Poisson com variância robusta. A prevalência de edentulismo foi 48,6% (n=137). No modelo multivariado final, idade, nível educacional e acesso ao dentista permaneceram associados com edentulismo. Para cada ano de aumento, há um aumento da razão de prevalência (RP) de 2,7% em ser edêntulos (RP: 1,027; intervalo de confiança de 95% [IC95%]: 1,015–1,039). Idosos com nível educacional médio/alto apresentaram 39,4% menor RP de ser edêntulos (RP: 0,606; IC95%: 0,382–0,961). Idosos sem acesso ao dentista presentaram 78% (p<0,001) maior RP de ser edêntulos quando comparado com aqueles que visitaram o dentista nos últimos 12 meses. A prevalência de edentulismo nos idosos foi alta e esteve associado com variáveis sociodemográficos e acesso ao dentista. Palavras-chave: Idoso. Perda de Dente. Fatores de Risco. Epidemiologia.

Prevalence and associated factors of self‐reported halitosis among institutionalized adolescents: cross‐sectional study

OBJECTIVE

To assess the prevalence and associated factors of self-reported halitosis in institutionalized adolescents in a city in southern Brazil.

METHODS

This cross-sectional study involved male institutionalized adolescents, aged 15-19 years old, at the Socio-Educational Assistance Center in the city of Passo Fundo, Brazil. Data collection was performed by a research team composed of two interviewers, two clinical examiners of oral health and two examiners of salivary flow. A structured questionnaire was applied, which included demographical, socioeconomical, general health behaviour, presence of health problems and oral health self-perception variables. Decayed, Missing, Filled Index was used for the clinical examination. The salivary flow collection was performed using the mechanically stimulated total saliva method, in which only the liquid component was measured.

RESULTS

The prevalence of self-reported halitosis in this sample was 51.5% (n = 35). In the final multivariate analysis, halitosis was significantly associated with the non-white racial group (prevalence ratio [RP]:1.703; 95% confidence interval [95%CI]:1.101-2.634), use of crack (RP:1.857; 95%CI:1.270-2.714) and number of decayed teeth (PR: 1.123; 95%CI:1.008-1.252). The use of alcohol and access to dental care in the last 12 months were not significantly associated with self-reported halitosis.

CONCLUSION

It was concluded that non-white and crack-user youngsters had a high occurrence of self-reported halitosis. Higher rates of dental caries are also associated with halitosis.

Concern of adolescents in conflict with the Law about their oral health

Objective: To assess the self-perception of adolescents in conflict with the law about their concern with oral health, in addition to tracing their relationship with other related variables. Methods: A cross-sectional study involving male institutionalized adolescents in a city in southern Brazil who underwent clinical examination and interviews to understand their concern for their oral health and the relationship between this outcome and associated factors. Concern about oral health was obtained through a validated questionnaire. Two fitted models were performed using Poisson regression (α < 0.05). One of them used the decayed, missing, and filled teeth index (DMF-D), and another considered the components of this index as exploratory variables. Results: Sixty-eight adolescents were included, and a high occurrence (75%) of concern about their oral health was observed. In the final multivariate analysis that included DMFT, this index (prevalence ratio [PR]: 1.033; 95% confidence interval [95%CI]: 1.004 – 1.063) and concern about tooth color (PR: 2.208; 95%CI: 1.028 – 4.740) were significantly associated with oral health concerns. When the various index components were included in the multivariate model, only the number of decayed teeth (PR: 1.073; 95%CI: 1.007 – 1.144) and concerns about tooth color (PR: 2.250; 95%CI: 1.057 – 4.793) were associated with the outcome. Conclusion: Institutionalized adolescents are highly concerned about their oral health, being associated with a DMF index, especially the decayed component, and a concern with the color of their teeth.

Prevalence of tooth loss and associated factors in institutionalized adolescents: a cross-sectional study

This study aimed to assess the prevalence of tooth loss and associated factors in institutionalized adolescents. This cross-sectional study included 68 male adolescents incarcerated from Socio-Educational Assistance Center (CASE) aged between 15 and 19 years. Questionnaires were applied individually to assess sociodemographical, economical, medical, behavioral and oral health self-perception variables. All present teeth were evaluated by Decay, Missing, Filling (DMF) Index. The prevalence of tooth loss was analyzed in individuals with ≥1 tooth loss. Associations between tooth loss and exposure variables studied were analyzed by Poisson Regression with robust variance estimation. The prevalence of tooth loss was 47.06%. First molars in the mandible and maxilla and central incisor in the maxilla were the most absent teeth. In the multivariate model, number of decayed teeth, and those that reported daily use of medication were associated with higher tooth loss. Besides, tooth loss was associated with decayed tooth and daily use of medication. Oral health promotion and treatment should be implemented in these institutions to reduce the prevalence of dental loss in these adolescents.

Pairs of natural teeth rather than use of dental prosthesis are associated with nutritional status in older adults: A cross-sectional study

OBJECTIVE

To evaluate the association between pairs of natural teeth and nutritional status among older adults.

METHODS

This cross-sectional study evaluated a total of 569 home-dwelling adults from two southern Brazilian cities aged ≥60 years. Present teeth were counted, and pairs of natural teeth were defined as antagonistic teeth. Nutritional status was assessed using Mini Nutritional Assessment. Sociodemographic, behavioral, medical and dental history were collected. Sample was dichotomized into well-nourished and at nutritional risk (including at risk of malnutrition and malnourished). Multiple multivariate models were performed considering different categorizations of pairs of natural teeth.

RESULTS

For each number of present teeth, a decrease of 1.8 % in the prevalence ratio (PR) for nutritional risk was detected (p = 0.040). For each pair of natural teeth, there was 4.4 % decrease in PR for nutritional risk (95 % confidence interval [95 % CI]: 0.917 - 0.997). No statistically significant association was found for pairs of natural anterior teeth (p = 0.222). For pairs of natural premolar, molar and posterior teeth, reductions of 15.4 %, 22.8 % and 11.5 %, respectively, in PR for nutritional risk were observed (p < 0.05). The presence of at least two pairs of natural molars or three pairs of natural posterior teeth was significantly associated with nutritional risk (p < 0.05).

CONCLUSION

Older adults with fewer teeth or pairs of natural teeth, especially posterior teeth, presented poorer nutritional status.

CLINICAL SIGNIFICANCE

Demonstrating threshold correlation between natural teeth and nutrition, data showed significant association between at least two pairs of natural molars or three pairs of natural posterior teeth and lower nutritional status.

Obesity is associated with lack of access to dental care and physical activity among older adults: a cross-sectional study

OBJECTIVE: This study evaluated the prevalence of obesity and associated factors among older adults. METHODS: This was a household-based cross-sectional study involving 282 individuals aged ≥ 60 years recruited in the city of Veranópolis, Brazil, using random probabilistic sampling. Participants underwent a clinical oral examination and completed a structured questionnaire. Obesity was determined based on body mass index (BMI). Individuals were divided into two groups based on the presence (BMI ≥ 30 kg/m2) or absence of obesity (BMI < 30 kg/m2). Uni- and multivariate analyses were performed using Poisson regression with robust variance. RESULTS: The prevalence of obesity was 34% (n = 96). Each 1-year increase in age resulted in a 3.09% decrease in the likelihood of being classified as having obesity (prevalence ratio [PR] = 0.969; 95% confidence interval [95%CI] 0.949 – 0.989). Older adults that reported walking < 5 or ≥ 5 times per week were 39.65 and 37.20% less likely to be classified as obese. The PRs of obesity in former and non-smokers were 4.40 and 5 times higher, respectively, than in current smokers (p < 0.05). Older adults with no access to dental care were 51.72% (p = 0.013) more likely to present with obesity. CONCLUSIONS: There was a high prevalence of obesity among older adults. Obesity was associated with lower age, smoking status, no access to dental care, and a lack of physical activity.

Oral health-related quality of life and associated factors in the elderly: a population-based cross-sectional study

Abstract This study aimed to evaluate the oral health-related quality of life (OHRQoL) and associated factors in the elderly. A cross-sectional study was conducted with 287 elderly of Cruz Alta, Brazil. The following variables were collected: age, sex, ethnicity, level of education, marital status, retirement, medical/dental history, smoking/alcohol exposure, oral hygiene habits, use and need of dental prosthesis, missing teeth, temporomandibular disorder symptoms (TMD), nutritional status, and halitosis. OHRQoL was assessed by Oral Health Impact Profile-14 (OHIP-14). The sample was categorized into low impact (sum scores ≤6) and high impact (sum scores ≥7). Associations were analyzed by Poisson regression with robust variation. Mean scores of OHIP-14 was 5.92±8.54. Divorced individuals and those who did not use dental floss presented 77% and 54%, respectively, higher prevalence ratio (PR) of having higher OHRQoL impact. Elderly that did not need dental prosthesis demonstrated a lower impact on OHRQoL (P<0.01). Elderly with TMD presented a higher PR of having higher OHRQoL impact (P<0.01). It was concluded that higher impact on OHRQoL was associated with marital status, non-users of dental floss and those with TMD. No need dental prosthesis were associated with lower impact on OHRQoL.

Concern with dental appearance and associated factors among the elderly of two southern Brazilian cities

Aim: This study aimed to evaluate the prevalence of concern with dental appearance (DA) and associated factors among the elderly of two southern Brazilian cities. Methods: A cross-sectional study was conducted in the cities of Cruz Alta and Veranópolis, Brazil. Oral health examination and a structured questionnaire were applied. Questions from the PCATool-SB Brasil tool and the Questionnaire about Teeth Appearance, both validated to Brazilian samples, were used. The collected independent variables were: sex, age, ethnicity, education level, marital status, retirement, health problem, use of medication, smoking exposure, alcohol exposure, access to the dentist, toothbrushing frequency, use of dental floss, edentulism, use of and need for dental prosthesis. Concern with DA was dichotomized into yes/no. Associations between dependent and independent variables were assessed by Chi-square or Mann-Whitney tests. Moreover, uni- and multivariate analyses were conducted by Poisson regression with robust variance. Level of significance was established as p<0.05. Results: The prevalence of concern with DA was 18.8% (n=107). The prevalence ratio (PR) of concern with DA decreased 5.8% for each year increase (PR:0.942; 95% confidence interval [95%CI]:0.911–0.973). Elderly without access to the dentist in the last 12 months presented 62.5% (p=0.006) higher PR of concern with DA when compared to those with access to dental care. Dentate elderly showed 219% higher PR for concern with DA (PR:2.197; 95%CI:1.364–3.539) in comparison to edentulous individuals. Conclusion: Prevalence of concern with DA was low and associated with demographics, access to dental care and edentulism.

Oral health-related quality of life and associated factors in institutionalized adolescents: a census study

This study aimed to associate oral health-related quality of life (OHRQoL) and related factors in adolescents deprived of freedom. In this cross-sectional observational study, sixty-eight male adolescents deprived of freedom (from the Socio-Educational Assistance Centers from Passo Fundo, Brazil)  were included. The sample was dichotomized into those with lower impact (sum scores <16) and higher impact (sum score ≥16) on OHRQoL. Sociodemographic characteristics, medical and dental histories, and a structured questionnaire about dental perception were collected. Clinical examination was performed by using the Decayed, Missing, Filled Index. Associations between the outcome and independent variables were analyzed by uni- and multivariate Poisson regression with robust variation. Overall, a mean score OHIP-14 was 13.15±11.17. In the multivariate analysis, former smokers and current smokers presented a significant higher prevalence ratio (PR) of higher OHIP-14 scores than nonsmokers (PR= 4.70; 95%CI: 1.21–18.22 and 4.83; 95%CI:1.25–18.58, respectively). Additionally, to every decayed tooth, a significant increase in the PR of having higher OHIP-14 was 28% (PR=1.28 – 95%CI: 1.11–1.47). Conversely, adolescents that were not concerned about teeth alignment presented a significantly lower PR of being in the higher impact of OHRQoL (PR=0.42 – 95%CI: 0.19–0.93). Adolescents deprived of freedom present a high impact on OHRQoL. The number of decayed teeth and smoking exposure were associated with higher impact on OHRQoL. However, absence of teeth alignment concern was associated with lower impact on OHRQoL.   Keywords: Quality of Life. Adolescent. Institutionalized. Psychometrics. Adolescent Health Services.   Resumo Esse estudo objetivou associar a qualidade de vida associada a saúde bucal (QVASB) e fatores relacionados em adolescentes privados de liberdade.

Low concern rate with oral health and associated factors among older persons: a cross-sectional study

OBJECTIVE: This study aimed to assess the prevalence of concern with oral health and associated factors among older adults. METHODS: Individuals aged ≥60 years were included from the cities Cruz Alta and Veranópolis, Brazil. Oral health examination and a structured questionnaire were applied in 569 individuals. The main outcome was concern with oral health (yes or no), which was determined by a validated questionnaire. Uni- and multivariate analyses were conducted by Poisson regression with robust variance to assess the association between outcome and independent variables. RESULTS: The prevalence of concern with oral health was 30.58% (n = 174). Non-white individuals presented significantly higher prevalence ratio (PR) of being concerned about their oral health (PR = 1.28; 95% confidence interval [CI] 1.01–1.62). Individuals with medium or high level of education, not retired and without any health problems presented higher PR of being concerned with their oral health when compared to their controls (p < 0.05). Moreover, those that reported toothbrushing frequency ≥ 2 times/day (PR = 1.58; 95%CI 1.01 – 2.48) and non-edentulous (PR = 1.50; 95%CI 1.12 –2.01) also presented higher PR of being concern with their oral health. Older adults that were not concerned with tooth alignment (PR = 0.57; 95%CI 0.44 – 0.74) or tooth color (PR = 0.41; 95%CI 0.31 – 0.54) demonstrated lower concern with their oral health. CONCLUSION: Prevalence of concern with oral health among the older adults was low and associated with non-white individuals, medium and high level of education, individuals not retired, absence of health problems, higher toothbrushing frequency, mild temporomandibular disorder (TMD) and non-edentulism. Additionally, concern with esthetical aspects may be related with this outcome.

Tooth loss and associated factors in adolescents – impact of extractions for orthodontic reason

Aim: To investigate tooth loss and its determinants in adolescents, considering the effect of extractions due to orthodontics reasons. Methods: This cross-sectional study was performed in students from public and private schools aged 15-19 years old from Passo Fundo, Brazil. The proportional randomly chosen sample included 736 adolescents. Clinical examinations and interviews were performed. Associations between prevalence of tooth loss and exposure variables studied were analysed by Poisson Regression with uni- and multivariate robust variance in two models. One model comprised students who had experienced tooth loss without orthodontic reasons and the other with all of the subjects presenting tooth loss. Results: Prevalence of tooth loss was 21.1% (mean of 0.42). Higher chances for tooth loss were found in the following features:  non-whites (PR=1.72; CI95%:1.15-2.60), poorly schooling mothers (PR=2.2; CI95%:0.96-5.02), from public schools (PR=4.16; CI95%:0.98-17.59), smokers (PR=1.91; CI95%:1.15-3.17). Conclusion: Demographic, socioeconomic and behavioural conditions were strongly associated with tooth loss. These associations were more evident when extractions for orthodontic reasons were not included in the analytical models.

Oral Health-Related Quality of Life and Associated Factors in Brazilian Adolescents

This study aimed to assess the impact of oral health on the quality of life of adolescents. A cross-sectional study was performed with students from public and private schools from Passo Fundo, Brazil. All students were aged between 15 and 19 years old. The proportional random sample consisted of 736 adolescents from 20 schools. A structured questionnaire was applied, and an oral examination was performed, counting the number of teeth. Oral health-related quality of life was assessed by OHIP-14. Associations between quality of life and associated factors were analyzed. The mean OHIP-14 score was 7.25. Age, ethnicity and studying in a public school were associated to the OHIP-14 score. Tooth loss (p=0.79) was not associated with quality of life. Additionally, questions related to appearance, such as whether teeth appearance bothers the adolescent (p=0.68) were not associated with quality of life. Attending a public school (OR=1.63; CI95%: 0.98-2.70) and self-reported halitosis (OR=1.48; CI95%: 1.01-2.16) were strongly associated to higher impact on quality of life. It was concluded that socioeconomic conditions and halitosis were associated to higher impact on quality of life of adolescents.

Factors associated with changes in self-reported dentifrice consumption in a brazilian group from 1996 and 2009

The aim of the study was to determine factors associated with changes in self-reported dentifrice consumption in an urban population group over 13 years. This study evaluated two surveys of 671 and 688 households sampled in the urban area of a city from Southern Brazil in 1996 and 2009, respectively. The mother of the family was asked to answer a structured questionnaire about demographics, socioeconomic and behavioral variables. The primary outcome was obtained by questioning "how long does a dentifrice tube last in your house?" The cut-off point of duration was less than 1 month. It was used to determine high consumption of dentifrice (HCD). Associations between HCD and independent variables were evaluated by multivariable Poisson regression. There was a significant decrease of 20% (81.2% to 61.2%) in the prevalence of HCD between 1996 and 2009, resulting in a crude annual decrease of 1.54%. Mother's age, family income, dental assistance, mother's brushing frequency and number of household members that use a toothbrush were significantly associated with HCD independent from the year of survey. The prevalence ratio (PR) of HCD for the year of survey was 0.75, indicating an overall decrease of 25% in the probability of HCD from 1996 to 2009. Probabilities of HCD also decreased over the 13 years among the strata of education, number of household members and reason for choice of dentifrice. It may be concluded that the factors associated with the observed decrease were higher educational levels, larger number of household members and reasons for choosing a dentifrice related to preventive/therapeutic effects.

Consumo de dentifrício e fatores associados em um grupo populacional brasileiro

Este estudo transversal avaliou o consumo de dentifrício fluoretado e fatores associados em Passo Fundo, Rio Grande do Sul, Brasil. Seiscentos e oitenta e oito domicílios foram selecionados. Um questionário estruturado foi respondido pela mãe para obter dados demográficos, hábitos e consumo de dentifrício. O consumo foi avaliado por intermédio da duração de um tubo de dentifrício e considerado baixo (duração > 1 mês) e alto (duração < 1 mês). Modelos de regressão logística avaliaram a associação do consumo com variáveis independentes. Foi observado que 61,2% dos domicílios apresentaram alto consumo de dentifrício. No modelo multivariado, idade da mãe > 50 anos (OR = 1.62; IC95% 1,02-2,61), frequência de escovação da mãe (OR = 2,53; IC95%: 1,53-4,16), número de moradores que utilizam escova (OR = 5,69; IC95%: 3,68-8,81) e motivo cosmético para escolha do dentifrício (OR = 1,64; IC95%:1,03-2,61) representaram maior chance de alto consumo de dentifrício. Conclui-se que a maioria dos domicílios apresenta consumo elevado de dentifrício, associado com idade e frequência de escovação da mãe, número de moradores e motivos de escolha.
