The impact of oral health on quality of life of urban and riverine populations of the Amazon: A multilevel analysis

Current status and factors of periodontal disease among Japanese high school students: a cross-sectional study

INTRODUCTION

This study aimed to investigate the prevalence of periodontal disease and the factors of the disease among high school students.

METHOD

The participants were all students aged 15-18 years (n = 1202) at a high school in Japan. The data on oral health perceptions and behaviours were collected by a questionnaire survey. The prevalence of periodontal disease among them was investigated with the partial community periodontal index (PCPI). A logistic regression analysis was used to identify the factors associated with the PCPI.

RESULTS

A total of 1069 students (88.9%) participated in this study. The prevalence of gingival bleeding, calculus, pocket depth of 4-5 mm, and pocket depth of 6 mm or more were 44.2%, 42.2%, 11.4%, and 1.6%, respectively. Approximately one-third of the students had a fear of dental treatment, and only 28.4% used dental floss. The results of logistic regression analysis, adjusted for sex and school year, showed that not visiting dentists regularly, not using dental floss, brushing teeth for less than 5 min, fear of dental treatment, and drinking sports drinks frequently were positively associated with periodontal conditions.

CONCLUSION

This study identified a high prevalence of periodontal disease among Japanese high school students aged 15-18 years and its risk factors, such as poor oral health behaviours and fear of dental treatment.

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.

Prevalence of periodontal disease in middle-aged and elderly patients and its influencing factors

OBJECTIVE

To explore the prevalence of periodontal disease in middle-aged and elderly patients and analyze its influencing factors.

METHODS

A total of 521 patients admitted to the Department of Stomatology of Fuyang District Chinese Medicine Hospital of Hangzhou from January 2019 to January 2022 were retrospectively collected as study subjects, including 176 patients aged 35-44 years old, 175 patients aged 45-64 years old, and 170 patients aged 65-74 years old. Community Periodontal Index (CPI) probe was used to detect gingival bleeding, periodontal pockets and attachment loss, and the prevalence of periodontal disease and its influencing factors were analyzed.

RESULTS

In the age group of 35-44, gingival bleeding was detected in 165 (93.75%) cases and dental calculus was detected in 176 (100.00%) cases; in the age group of 45-64, gingival bleeding was detected in 163 (93.14%) cases and dental calculus was detected in 161 (92.00%) cases; in the age group of 65-74, gingival bleeding was detected in 150 (88.24%) cases and dental calculus was detected in 162 (95.29%) cases. There were statistically significant differences in the detection rates of shallow periodontal pockets, deep periodontal pockets, and loss of periodontal attachment among the three groups (P<0.05). There wasalso asignificant difference in the detection rate of periodontitis among the three groups (P<0.05). Univariate analysis showed that gender, age, place of residence, smoking, alcohol consumption, brushing frequency, and dental cleaning in the past year were all associated with the occurrence of periodontitis (P<0.05). Logistic multi-factor regression analysis showed that age was a risk factor for the development of periodontitis in middle-aged and elderly patients (P<0.05).

CONCLUSION

The prevalence of periodontal disease in middle-aged and elderly individuals is high, with a high prevalence of gingival bleeding and shallow periodontal pockets. Age is an influencing factor on the incidence of periodontitis in middle-aged and elderly individuals.

Determinants of oral-health-related quality of life among adult people in Iran

BACKGROUND

Oral health-related quality of life (OHRQoL) assesses the subjective perception of oral health and its impact on the quality of life. The aim of this study is to measure the OHRQoL and its determinants among adult people living in Kerman, Iran.

MATERIALS AND METHODS

In this cross-sectional study, a total of 5657 adult people (18-64 years) residing in the Kerman district, both in the rural and urban areas, were enrolled in the study between September 2014 and April 2018. The Oral Health Impact Profile (OHIP-14) and the oral health indices, such as the total decayed, missing, filled teeth (DMFT), community periodontal index (CPI), gingival index (GI), and xerostomia, were measured by an experienced dentist. The demographic variables of gender, age, educational status, and marital status were also recorded. The impact of the studied variables on OHRQoL was evaluated with multiple logistic regression.

RESULTS

Participants were 2239 (39.58%) men, and average age was 45.39. The mean scores for OHRQoL, DMFT, CPI and GI were respectively: 24.07 (7.76), 10.7 (6.86), 0.76 (0.96), 0.63 (0.8). The frequency of people with xerostomia was 37.4. 301 (53.3%) of people had poor quality of life related to oral health. In multivariable analysis, there was a statistically significant increase in OHRQoL with an increase in the DMFT (P < 0.001), xerostomia (P < 0.001), CPI, (P < 0.001). Men had a significantly higher OHIP score than women (P < 0.001).

CONCLUSION

According to the results of this study, DMFT, xerostomia, and CPI scores are strongly related to OHIP scores. In addition, between CPI and GI scores, the CPI score is the better predictor.

Prevalence, Extent, and Severity of Oral Health Impacts Among Adults in Rural Karnataka, India

INTRODUCTION

Oral health affects quality of life. Many studies have investigated the factors associated with oral health-related quality of life (OHRQoL). Little is known about OHRQoL of adults living in rural and remote areas of India, where many have lower levels of education and limited availability of oral health care services.

OBJECTIVES

To determine the prevalence, extent, and severity of OHRQoL impacts associated with psychosocial factors, functional dentition, and patterns of dental visits among rural Indian adults between the ages of 35 and 54 y.

METHODS

A cross-sectional study was conducted with a multistage stratified sampling strategy targeting 35- to 54-year-olds. Interviews and oral examinations were performed to collect data on sociodemographic variables, Oral Health Impact Profile-14 (OHIP-14), patterns of dental visits, stress, tobacco and alcohol use, and dentition status. Univariate, bivariate, and multivariable analyses were done to determine the factors associated with prevalence, extent, and severity of OHIP-14 using SAS version 9.3.

RESULTS

There were 873 participants. Prevalence, extent, and severity of OHIP-14 were 13.4%, 0.5 (0.4-0.7), and 11.8 (11.2-12.5), respectively. The OHIP-14 impacts reported were not severe and mostly affected physical functioning. Levels of education, income, and number of functional teeth (FT) were inversely associated and last dental visit within the previous year was positively associated with prevalence, extent, and severity of OHIP-14. The prevalence of 1 or more oral health impacts was nearly 13% among rural middle-aged adults in India.

CONCLUSIONS

Low socioeconomic conditions, dental visits, and FT ≤19 were positively associated with prevalence, extent, and severity of oral health impacts.

KNOWLEDGE TRANSFER STATEMENT

This article provides data regarding OHRQoL of people in rural areas of a developing country. The study was intended to determine the factors associated with OHRQoL in rural people who are less educated and living in areas with minimal oral health care facilities. The findings of this study could potentially facilitate further research and health promotional activities for rural people of developing countries.

The association of socio-economic status, dental anxiety, and behavioral and clinical variables with adolescents' oral health-related quality of life

PURPOSE

It is not clear which factors hold more weight in predicting oral health-related quality of life (OHRQoL). Therefore, this study explored which component of factors (e.g., socio-economic status, clinical status or oral health behaviors, dental anxiety, oral health knowledge) has a better predictive value in different aspects (e.g., oral symptoms, functional limitations, social and emotional conditions) of adolescents' OHRQoL.

METHODS

Participants were randomly selected from Grade Two (S2) students within 12 secondary schools in Hong Kong. The independent variables include the following : socio-economic (monthly family income, parents' educational background), oral health behaviors (the frequency of brushing and having snacks like chocolate or biscuits), and oral health-related factors (oral health knowledge, dental anxiety, dental caries and bleeding index). Adolescents' OHRQoL was evaluated using the 16-item Child Perception Questionnaire (CPQ_11-14-ISF:16). Frequencies and means were used for data description. Different variables were analyzed as predictors of OHRQoL by multi-level linear regression analysis.

RESULTS

1207 adolescents (46.6% females) participated in this study. The mean total CPQ_11-14-ISF:16 was 14.2 (9.8). Mean scores of oral symptoms, functional limitations, and emotional and social well-being were 4.4 (2.8), 4.2 (2.8), 3.2 (3.1), and 2.4 (2.7), respectively. In the final model, adolescents with poorer oral health knowledge, higher dental anxiety levels, brushed their teeth less than once a day and consumed chocolates or biscuits more regularly as reported by a statistically worse OHRQoL (p < 0.05). In addition, gingival bleeding was a predictor of the oral symptom domain (β = 0.7, p = 0.027); the emotional well-being of adolescents whose father went to college had a better OHRQoL (β =  - 0.9, p = 0.014) and adolescents from the higher-income family had a statistically better social well-being (p = 0.015).

CONCLUSION

Our study indicates that adolescents with poorer oral health knowledge, higher dental anxiety levels, brushing their teeth less than once a day, or having a daily consumption of chocolate or biscuits had statistically worse OHRQoL. These findings can provide guidance for future oral health promotion in improving OHRQoL among adolescents.

Study protocol of the cost-effectiveness comparison of two preventive methods in the incidence of caries: A randomized, controlled clinical trial

INTRODUCTION

Dental caries is the most frequent oral disease worldwide and the main cause of tooth loss in children and young adults. One of the most frequently affected areas is the occlusal surfaces of the first permanent molars (FPM) due to their morphological complexity. At present, several preventive treatments can reduce the incidence of this disease in school populations. In Mexico, the most commonly used technologies are those derived from some presentation of fluoride; on the other hand, research on this topic has been limited.

OBJECTIVE

To determine the cost-effectiveness of two different methods for preventing the incidence of caries on the FPM of schoolchildren (6-8 years of age) from public primary schools.

MATERIAL AND METHODS

This is a randomized experimental design. Participants will be assigned to two treatment groups of 114 each. In the first group, pit and fissure sealants will be applied, whereas the second group will receive a fluoride varnish. The work will be carried out in schoolchildren that attend public elementary schools in the state of Hidalgo, Mexico. The result variable will be the incidence of caries and the total cost of each of the interventions will be calculated in order to calculate the intervention's cost-effectiveness.

CONCLUSION

This work will allow us to compare the cost-effectiveness of the pit and fissure sealants and the fluoride varnish in order to determine which offers the best results.
