Periodontal diseases and potential risk factors in Egyptian adult population-Results from a national cross-sectional study

Disparities and social determinants of periodontal diseases

Periodontal diseases are highly prevalent in populations worldwide and are a major global public health problem, with major negative impacts on individuals and communities. This study investigates evidence of disparities in periodontal diseases by age groups, gender, and socioeconomic factors. There is ample evidence that these diseases disproportionally affect poorer and marginalized groups and are closely associated with certain demographics and socioeconomic status. Disparities in periodontal health are associated with social inequalities, which in turn are caused by old age, gender inequality, income and education gaps, access to health care, social class, and other factors. In health care, these factors may result in some individuals receiving better and more professional care compared to others. This study also reviews the potential causes of these disparities and the means to bridge the gap in disease prevalence. Identifying and implementing effective strategies to eliminate inequities among minorities and marginalized groups in oral health status and dental care should be prioritized in populations globally.

Association between dry eye and periodontal disease in community-dwelling Japanese adults: data from the Uonoma cohort study

BACKGROUND

While research has explored the risk of periodontal disease in various eye conditions, the link between dry eye and periodontal disease remains underexplored, especially in Japanese adults. This study aims to investigate the association between dry eye and periodontal disease in community-dwelling Japanese adults.

METHODS

This study is a subset of the Uonuma cohort study, which includes Japanese adults aged 40 years and older residing in the Uonuma area of Niigata Prefecture, Japan. Participants completed a self-administered, paper-based questionnaire. Statistical analyses, including the chi-square test, independent t test, ANOVA test, and logistic regressions, were employed to assess the association of periodontal disease with independent variables.

RESULTS

Among 36,488 participants (average age 63.3 years, 47.4% men), 39.3% had a history of periodontal disease, and gender differences were statistically significant (p < 0.001). Significant associations were found between periodontal disease and dry eye diagnosis or symptoms. Univariable logistic regression revealed links between periodontal disease and age, gender, living status, alcohol consumption, remaining teeth, bite molar availability, and history of dry eye disease or symptoms. Multiple-adjusted regression found that doctor-diagnosed dry eye was associated with a higher likelihood of periodontal disease (odds ratio, 1.12; 95% confidence interval, 1.03-1.22). Participants who never experienced dryness or foreign body sensation had lower ORs of periodontal disease than those who always experienced such symptoms across all models.

CONCLUSION

A significant correlation was found between dry eye and periodontal disease in Japanese adults. Regular check-ups, early detection, and effective management of both conditions are strongly recommended.

Periodontal Status and Potential Risk Factors in the Myanmar Population: Data from the First National Oral Health Survey in 2016-2017

ABSTRACT

Periodontal disease is quite common in many developing countries, but no nationally representative data on periodontal disease is available in Myanmar until 2016. A nationwide cross-sectional survey with a stratified two-stage sampling method was conducted among 4668 participants aged 12-74 years. Periodontal assessments and self-administered questionnaire surveys were conducted to assess the periodontal status and risk factors in the Myanmar population using data from the first national oral health survey in 2016-2017. Descriptive statistics and logistic regression analysis were performed to assess the prevalence of periodontitis and its association with potential risk factors. The prevalence of gingivitis was 38.2%, 41.5%, 44.4%, and 43.7% in 12, 15-18, 35-44, and 60-74 year-olds, respectively. The prevalence of periodontitis in the latter three age groups was 2.3%, 16.3%, and 35.2%, respectively. After adjusting for other risk factors, younger participants aged 15-18 years (odds ratio [OR]: 0.1, 95% confidence interval [95% CI]: 0.0-0.2) and aged 35-44 years (OR: 0.4, 95% CI: 0.3-0.5) were less likely to have periodontitis. Moreover, participants educated upto junior high school level (OR: 1.6, 95% CI: 1.1-2.7), primary school and below level (OR: 1.9, 95% CI: 1.2-3.2), everyday smokers (OR: 1.6, 95% CI: 1.3-2.0), and everyday tobacco chewers (OR: 1.5, 95% CI: 1.2-1.8) were associated with increased risk of periodontitis. Periodontal complications were prevalent in Myanmar older adults. Prevention efforts should focus on tobacco control and oral hygiene.

Prevalence, Predictors, and Reasons for Permanent Tooth Extraction Among High School Students in Saudi Arabia: A National Cross-Sectional Study

Background

Tooth loss is a major dental health concern that has adverse consequences on the remaining dentition and on the patient’s general well-being. This present study aimed to assess predictors and causes of permanent tooth extraction among students.

Methods

This national cross-sectional study in Saudi Arabia included a random sample of school students of both genders from grades 10 to 12 (15-18 years of age) and spanned the period of September 2012 to January 2016. Demographic, social, and medical history were recorded. Moreover, a list of possible reasons for tooth extraction was discussed with participants and their parents. The questionnaire was divided into two parts. They first asked for the patient's gender, age, marital status, education level, history of smoking, and the time of the last dental visit. Periodontal and dental examinations were performed. Multivariable logistic regression was used to determine predictors of tooth loss among the sample.

Results

A total of 2,435 school students were included in the study. Notably, 24% of the students had extractions of at least one permanent tooth. Nearly 27% of female students had a permanent tooth extraction compared with only 21.7% of male students, which was statistically significant. Students who visited dentists regularly had significantly more tooth extractions (39%) than students who did not (20.6%). Multivariate logistic regression analysis showed that the significant predictors for permanent tooth extraction were age, regular dental visits, and mean probing depth (PD). Caries (15%) followed by orthodontic treatment (6%) were the main reason for permanent tooth extraction among the sample.

Conclusion

Caries was responsible for most of the tooth loss among the study population. Significant predictors for permanent tooth extraction were age, regular dental visits, and mean probing depth. It follows that there is a need for intensified oral health education and awareness programs in the population with an emphasis on the prevention of dental caries.

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.
