Association Between Arterial Hypertension and Periodontal Status in Morbidly Obese Patients Who Are Candidates for Bariatric Surgery

Class 3 Obesity and Oral Health in Adults: A Scoping Review of the Challenges for Oral Healthcare Services

Background: Obesity is one of the most neglected public health problems affecting both developed and developing countries. The most clinically severe obesity (Class 3 obesity) has both clinical and service delivery implications on dental services. However, associations between Class 3 obesity and oral health are minimally explored in the literature and thus poorly understood. Aims: This scoping review aimed to explore the existing evidence on Class 3 obesity and oral health. Methods: A literature search was performed via Medline, Scopus, Google scholar and Embase research databases. Results: A total of 375 papers were sourced from the database search. Twenty seven full-text papers were included in the final literature review. Results revealed findings from both quantitative and qualitative studies. Papers included results pertaining to associations with dental disease, oral health and associated behaviours, oral health-related quality of life and the barriers experienced by adults with Class 3 obesity in accessing dental services. Conclusions: While mixed findings were identified, this scoping review reports associations between Class 3 obesity and poor oral health across various domains including clinical parameters and oral health related quality of life. The literature has also highlighted important barriers to dental care in those with the most severe Class 3 obesity. Based upon our findings, we have summarised current oral health management implications and directions for future research.

Periodontal and systemic health of morbidly obese patients eligible for bariatric surgery: a cross-sectional study

Background

In obese patients, periodontitis might be associated with deprived systemic health. Edmonton obesity staging system (EOSS) is a new tool for classification of obesity that considers the metabolic, physical, and psychological health. The cross-sectional study aimed to evaluate the periodontal status of morbidly obese patients eligible for bariatric surgery and the association between periodontitis, obesity-related comorbidities, and EOSS.

Methods

Morbidly obese patients eligible for bariatric surgery underwent detailed periodontal examination and were divided into the periodontitis group (PG) and the non-periodontitis group (NPG). The medical and demographic data were obtained from medical files, while behavioural data were obtained by the interview. Descriptive statistics and simple statistical tests were used to summarise the characteristics of the sample and the differences between PG and NPG. The logistic regression models were used to calculate the association (odds ratio (OR)) between periodontitis and obesity-related diseases and EOSS.

Results

The study included 79 patients, with an average BMI of 44.6 kg/m² (SD = 7.2). The prevalence of periodontitis was 65% (CI 95% 53%-75%). PG patients (n = 51) were older, more often smokers and were more often hypertensive than NPG patients (n = 28) (p < 0.05). Hypertension was positively associated with periodontitis with adjusted OR 3.98 (95% CI 1.23–12.8; p = 0.021)) and age with adjusted OR 1.06, (95% CI 1.01–1.13; p = 0.038)), while other tested conditions (diabetes, dyslipidaemia, and smoking habits) did not show significant association with periodontitis. Periodontitis did not correlate with EOSS or other obesity-related comorbidities (p > 0.05).

Conclusion

The morbidly obese patients eligible for bariatric surgery show a high prevalence of periodontitis and, therefore, are advised to be examined by a dentist before undergoing surgery. They have higher odds of hypertension but not of other obesity-related diseases or higher stages of EOSS. The medical personnel should raise awareness among obese patients on the potential association of poor periodontal health with hypertension.

Periodontal status and quality of life in pregnant women with both overweight/obesity and hypertension: A cross-sectional study

Background

The aim of this study was to assess the periodontal condition and quality of life of pregnant women affected with both overweight/obesity and arterial hypertension.

Material and Methods

Pregnant women were dived into three groups: with overweight/obesity and hypertension (G1 = 23), with overweight/obesity without hypertension (G2 = 31) and with normal BMI and without hypertension (G3 = 38). They were evaluated regarding: contextual variables (age, socioeconomic level and anthropometric parameters); periodontal status; and quality of life (adapted version of Oral Health Impact Profile – OHIP-14). ANOVA, Kruskal-Wallis, chi-square and binary logistic regression model were adopted (p< 0.05).

Results

There were no intergroup differences for age (p = 0.700), education level (p = 0.119) and gestational weight gain (p = 0.415), nevertheless G2 differed from G3 regarding household monthly income (p = 0.040). G2 had higher prevalence of bleeding on probing than G3 (p = 0.001), but G1 and G2 presented higher prevalence of periodontitis (p< 0.001). Household monthly income (adjusted OR = 0.71; 95% CI = 0.52 - 0.98; p = 0.038) and hypertension (adjusted OR = 3.70; 95% CI = 1.16 - 11.80; p = 0.026) remained in the final logistic regression model [X2(4) = 21.79; p = 0.0002; R2 of Nagelkerke = 0.284]. G1 showed worse impact on quality of life, mainly regarding physical pain (p< 0 .001), psychological discomfort (p< 0 .001), physical disability (p< 0 .001), social disability (p = 0.005) and handicap (p< 0 .001).

Conclusions

In conclusion, maternal excessive weight is associated with periodontitis during pregnancy. Moreover, the presence of hypertension in overweight pregnant women seems to be determinant to negatively influence their quality of life, resulting in physical, psychological and social damages.
