Depression and associated factors among Brazilian adults: the 2019 national healthcare population-based study.

BACKGROUND: Mental disorders represent a major public health challenge worldwide, affecting 80% of people living in low- and middle-income countries. Depression, a mental disorder, is a chronic disease of long duration that causes changes in the brain, resulting from a combination of genetic, physiologic, environmental, and behavioral factors. The aim of this study was to investigate possible factors associated with depression in Brazilian adults. METHODS: A population-based, cross-sectional study was carried out using the public domain database of the 2019 National Health Survey, conducted in Brazil. Depression was considered the dependent variable, and through hierarchical analysis, predictor variables were investigated such as, at the distal level-socioeconomic variables, at the intermediate level-variables related to lifestyle behavior, health condition, and history, and at the proximal level-demographic variables. Logistic regression analysis was used to obtain the adjusted Odds Ratio and the respective 95% confidence interval to identify possible factors associated with depression. RESULTS: The study included 88,531 participant records with 10.27% diagnosed with depression. The adjusted association measurements, after selecting the independent variables in the hierarchical analysis, showed the following factors associated with depression with differing magnitudes: age, brown and white race/skin color, female sex, poor, very poor, or regular self-reported health condition, diagnosis of cardiovascular disease, work-related musculoskeletal disorder, history of smoking habit, and macroeconomic region. CONCLUSIONS: An effective strategy for preventing and managing depression in Brazilian adults must include the control of health status and lifestyle behavior factors, with actions and programs to reduce people's exposure to these factors, understanding that socioeconomic-demographic differences of each population can potentially reduce the disease burden.

Periodontitis severity relationship with metabolic syndrome: A systematic review with meta-analysis.

The objective of this study was to investigate the association between periodontitis severity and metabolic syndrome (MetS) through systematic review, registered in PROSPERO: CRD42021232120. Selected articles were independently chosen by three reviewers from six databases, including using article reference lists, up until March 2022. Eligible studies were observational, without language limitation, and in subjects aged at least 18 years. The methodological quality of selected studies was assessed using the Newcastle-Ottawa Scale. Random effects models calculated summary measurements (odds ratio-OR, 95% confidence interval, 95%CI). The I2 test evaluated the statistical heterogeneity of the data. Sensitivity, subgroup, and meta-regression analyses were performed. For the reliability of evidence, the Grading of Recommendations, Assessment, Development, and Evaluations tool was used. A total of 2133 records were identified, and 14 studies were included comprising 24,567 participants. The summary odds ratio showed a positive association between individuals with moderate (ORadjusted  = 1.26; 95%CI = 2.10-5.37; I2  = 45.85%), and severe periodontitis (ORadjusted  = 1.50; 95%CI:1.28-1.71; I2  = 56.46%), and MetS. Subgroup and meta-regression analyses showed that study effect size was influenced by year of publication, study design, and MetS diagnostic criteria, contributing to inter-study variability. The findings showed that moderate and severe levels of periodontitis are associated with MetS, suggesting a possible dose-response effect.

Improving oral health of adolescent girls in Kenya through education - An observational study.

OBJECTIVES: Dental caries and periodontal diseases are significant health concerns in developing nations. This study assessed the impact of a comprehensive oral health education program on adolescent girls in rural Kenya. METHODS: Eighty-seven girls aged 13-18 years attending school in rural Nanyuki, Kenya, were enrolled in the study. The comprehensive program included personalized oral hygiene training, education and health advocacy coaching. Dental caries, gingival inflammation and dental plaque biofilm were assessed at baseline, 1- and 2.5-year post-implementation. RESULTS: The intervention was highly effective in arresting pre-existing carious lesions and preventing the formation of new ones in this population. The data revealed that there was a significant remineralization of incipient caries lesion, as shown by decreases in modified ICCMS™ scores from baseline to 1-year post-implementation. From baseline to the 2.5-year post-implementation assessment, only six new carious lesions developed. Dental plaque biofilm was reduced by 83.6%, and gingival inflammation was reduced by 81.6%. CONCLUSION: A comprehensive oral health program, which included behavioural awareness and educational approaches, resulted in significant positive oral health outcomes in caries, dental plaque biofilm and gingival inflammation.

Periodontitis is a factor associated with dyslipidemia.

OBJECTIVE: To investigate the association between the severity of periodontitis (exposure) and dyslipidemia (outcome). METHODS: This was a cross-sectional study of users of public health services. Periodontitis was defined using the Center for Disease Prevention and Control and the American Academy of Periodontology criteria. Lipid evaluation used data on systemic biomarkers. Dyslipidemia diagnosis was based on the Guidelines of total cardiovascular risk of the World Health Organization. Weight, height, waist circumference, and blood pressure were measured, and socioeconomic-demographic, lifestyle behavior factors, general and oral health conditions of the participants were collected. Hierarchical and logistic regression analyzes were used to determine the association between the exposures and the outcome. Odds Ratios, unadjusted and adjusted, and 95% confidence intervals were estimated. RESULTS: Of 1,011 individuals examined, 75.17% had dyslipidemia, and 84.17% had periodontitis, 0.2% with mild, 48.56% moderate, and 35.41% severe disease. The association between periodontitis and dyslipidemia was maintained through hierarchical analysis and in the multiple regression modeling, showing that the occurrences of dyslipidemia in the group with periodontitis, and its moderate and severe levels, were, respectively, 14%, 30%, and 16% higher compared with those without periodontitis. CONCLUSIONS: The results showed a positive association between moderate and severe periodontitis and dyslipidemia.

Obesity in young women is positively associated with periodontitis.

OBJECTIVE: This cross-sectional study was performed to investigate the association between excess body weight and periodontitis in adults, stratified by sex and age, and using different criteria for obesity. MATERIAL AND METHODS: Enrolled in the study were 345 individuals with a minimum age of 18 years who had attended the Public Health Service in the city of Salvador, Bahia, Brazil. All individuals underwent a complete periodontal examination and anthropometric measurements and answered a questionnaire regarding their socioeconomic, demographic, health, and lifestyle conditions. Excess body weight (exposure factor) was defined using body mass index (BMI) and waist circumference (WC). Prevalence ratios (PRs) and 95% confidence intervals (95%CI) were obtained by Poisson regression analysis with robust variance. RESULTS: Periodontitis was found in 74.2% of study participants, with the disease being more prevalent among those individuals with increased WC. The occurrence of overweight was 44.4% and that of obesity ranged from 29.9 to 70.8%, dependent upon the specific definition of obesity that was used. There was a positive association between obesity (WC > 88 cm) and periodontitis only among women, after adjustment for age, smoking habit, education level, diabetes, and family income (PRadjusted: 1.20; 95%CI: [1.01-1.44]). The magnitude of this positive association was higher among women aged 18 to 49 years when the outcome was severe periodontitis, and the exposure was obesity defined by WC. CONCLUSIONS: The findings draw attention to the high frequency of the diseases investigated: overweight, obesity and periodontitis. Moreover, obesity was positively associated with periodontitis in women and younger individuals, demonstrating that among those with obesity, there is a higher probability of having periodontitis. The smaller number study of men in the may have influenced the non-statistically significant association found in that group. CLINICAL RELEVANCE: Obese females and younger people are more likely to also have periodontitis. Periodontal evaluation and clinical management of individuals with obesity is recommended.

Obesity and periodontitis are not associated in pregnant women.

OBJECTIVE: The objective of this study was to investigate an association between obesity (exposure) and periodontitis (outcome) in pregnant women. BACKGROUND: This association was investigated and only five studies were identified as showing a positive association. However, some of these studies had limitations such as reduced sample sizes, inadequate exposure criteria and outcome measures, which question the internal validity of these investigations. METHODS: A cross-sectional study was carried out with a sample of 644 pregnant women of the public health service of the municipality of Santo Antônio de Jesus, Bahia, Brazil. Data were obtained by collecting of socioeconomic-demographic information, health behavior, health conditions, and reproductive history through an interview. Obesity was evaluated using body mass index adjusted for gestational age and expected weight gain. The diagnosis of periodontitis followed two criteria: (a) Center for Disease Prevention and Control and American Academy of Periodontology (CDC/AAP); (b) Gomes-Filho et al (2018) using criterion that also evaluated bleeding upon probing; Prevalence ratios and respective 95% confidence intervals were obtained by Poisson regression analysis. RESULTS: In accordance with the outcome diagnostic criterion, the frequency of periodontitis was 17.24% (Gomes-Filho et al) and 66.92% (CDC/AAP). The participants were classified as low weight (19.72%), adequate weight (42.39%), overweight (24.84%), and obesity (13.04%), based on the exposure diagnostic criterion. The low weight and overweight groups were excluded from the data analysis, giving a final sample of 357 pregnant women. The association between obesity in pregnant women and periodontitis was not statistically significant, after adjusting for confounders such as age, schooling level, alcoholic beverage consumption, alimentary and nutritional orientation, urinary infection, and dental flossing. CONCLUSIONS: The findings showed a high frequency of periodontitis, obesity, and overweight in the studied population but no association between obesity and periodontitis in pregnant women was found.

Gingival fenestration defect treated with gingivectomy and gingivoplasty: A case report with an 8-year follow-up.

INTRODUCTION: Gingival fenestration (GF) is scarcely reported in the literature. We present a unique case of GF defect combined with gingivitis and altered passive eruption (APE). CASE PRESENTATION: An 18-year-old female patient with gingivitis, APE, and GF in the mandibular left central incisor presented for periodontal treatment. The gingival lesion was successfully treated with basic periodontal therapy gingivectomy, and gingivoplasty and resulted in an excellent aesthetic long-term outcome. This case report shows its 8-year clinical follow-up. CONCLUSION: There are no earlier reports dealing with the use of gingivoplasty for the treatment of GF, as it is not the usual therapeutic intervention for these defects. Gingivoplasty proved to be effective in treating GF. Why is this case new information? Available literature on gingival fenestration defects does not describe gingivectomy and gingivoplasty as a treatment of choice. Gingivectomy and gingivoplasty proved to be effective in treating gingival fenestration defects. What are the keys to successful management of this case? Proper diagnosis. What are the primary limitations to success in this case? Gingival fenestration has been defined when the overlying gingiva is denuded, exposing the root to the oral cavity. However, in this case report, only the crown was exposed because the patient had altered passive eruption.

Periodontitis in individuals with few remaining teeth and a high gingival bleeding index increases the probability of dyslipidemia.

BACKGROUND: Dyslipidemia, a silent multifactorial condition, is characterized by changes in blood lipid levels, affecting all socioeconomic strata, increasing the risk for atherosclerotic diseases. This study investigated whether there is an association between dyslipidemia and the combined exposure of periodontitis plus the number of remaining teeth, gingival bleeding, or caries. METHODS: A two-center cross-sectional study was conducted involving 1270 individuals, with a minimum age of 18 years. Socioeconomic and demographic data, health conditions, lifestyle parameters, and anthropometric, biochemical, and oral clinical examinations were performed. The exposures considered were the presence of periodontitis, dental caries, number of remaining teeth, and gingival bleeding. The outcome was dyslipidemia as defined by the Brazilian Guidelines on Dyslipidemia and Prevention of Atherosclerosis. The combined associations between periodontitis plus other oral health conditions and dyslipidemia were estimated using confounder-adjusted prevalence ratios (PRsingle , PRmultiple , for single and multiple covariable adjustments) with 95% confidence intervals (95% CIs), in a Poisson regression model with robust variance. RESULTS: The occurrence of dyslipidemia was 70.1% and periodontitis was 84.1%. A positive association between periodontitis and dyslipidemia existed: PRsingle  = 1.13; 95% CI: 1.01-1.26. Combined exposure of periodontitis plus <11 remaining teeth (PRmultiple  = 1.23; 95% CI: 1.05-1.43), as well as combined exposure of periodontitis plus ≥10% gingival bleeding and <11 remaining teeth (PRmultiple  = 1.22; 95% CI: 1.03-1.44), represented greater probabilities of 23% and 22% of individuals having a diagnosis of dyslipidemia. CONCLUSION: Periodontitis combined with fewer than 11 teeth doubled the likelihood of being diagnosed with dyslipidemia.

Mothers' high glycemic levels and the association between periodontitis and low birth weight.

BACKGROUND: Maternal hyperglycemia, periodontitis, and adverse gestational outcomes are important health problems. The present study investigated the hypothesis that periodontitis and the glycemic level of mothers may have opposing influences on birth weight (BW). This study evaluated the effect of high glycemic levels, albeit within the normal range, on the association between periodontitis and low birth weight (LBW). METHODS: A total of 732 women took part in this case-control study; 172 were mothers of children with LBW <2,500 g, and 560 were mothers of children with BW ≥2,500 g. The BW of newborns was obtained from medical records, and information on socioeconomic-demographic, lifestyle behavior were obtained through interviews. Glycated hemoglobin (HbA1c) levels were evaluated, and full-mouth periodontal examination was carried out within 7 days postpartum. Hierarchical and logistic regression analysis evaluated the effect of glycemic levels on the association between periodontitis and LBW by subgroups, estimating odds ratios (OR) with 95% confidence intervals (95% CI). RESULTS: In the group with HbA1c levels <5.6%, a statistically significant relationship existed between periodontitis and LBW. Using the Centre for Disease Control/American Academy of Periodontics criteria, the ORadjusted was 1.55; 95% CI: 1.04 to 2.31; using the Gomes-Filho et al. criteria the ORadjusted was 1.91; 95% CI, 1.06 to 3.45. In the group with higher HbA1c levels but still within the normal range (≥5.6% and <6.5%), the findings showed no association between periodontitis and LBW. CONCLUSION: Higher maternal glycemic levels within the normal range, inferior to those indicative of gestational diabetes, diabetes mellitus, or hyperglycemia, and periodontitis have opposing effects on BW, altering the association magnitude.

Adjuvant therapy with 1% alendronate gel for experimental periodontitis treatment in rats.

PURPOSE: The aim of this study was to evaluate the effects of locally delivered 1% alendronate (ALN) gel used as an adjunct to non-invasive periodontal therapy. METHODS: Ligature-induced periodontitis was performed in 96 rats. The ligature was tied in the cervical area of the mandibular left first molar. The animals were randomly divided into 4 groups: 1) NT, no treatment; 2) SRP, scaling and root planning; 3) SRP/PLA, SRP followed by filling the periodontal pocket with placebo gel (PLA); and 4) SRP/ALN, SRP followed by filling the periodontal pockets with 1% ALN gel. Histomorphometric (percentage of bone in the furcation region [PBF]) and immunohistochemical (receptor activator of nuclear factor-κB ligand, osteoprotegerin, and tartrate-resistant acid phosphatase) analyses were performed. Data were statistically analyzed, with the threshold of statistical significance set at P≤0.05. RESULTS: The SRP, SRP/PLA, and SRP/ALN groups presented a higher PBF than the NT group (P≤0.01) at 7, 15, and 30 days. The SRP/ALN group presented a higher PBF than the SRP/PLA group in all experimental periods, as well as a higher PBF than the SRP group at 15 and 30 days. No differences were observed in the immunohistochemical analyses (P>0.05 for all). CONCLUSIONS: Locally delivered 1% ALN gel used as an adjunct to SRP enhanced bone regeneration in the furcation region in a rat model of experimental periodontitis.

An accuracy study of the clinical diagnosis of periodontitis in pregnant women.

BACKGROUND: There exists a diverse range of criteria used in epidemiological studies for the diagnosis of periodontitis. The results from these studies should be evaluated with consideration to the diagnostic criteria used, and this may account for differences between studies especially in some population groups such as pregnant females. The objective is to evaluate the diagnostic criteria used in a variety of epidemiologic studies of periodontitis in pregnant females. METHODS: An accuracy study with cross-sectional design was performed out from a database of 671 pregnant females, using six different sets of criteria for the diagnosis of periodontitis. Women were classified for periodontitis, as follows: Center for Disease Control and Prevention/American Academy of Periodontology (CDC/AAP, 2012 criterion), the gold standard, Gomes-Filho et al.(2018) criterion, Albandar et al.(2007) criterion, Bassani et al.(2007) criterion, López et al.(2002) criterion, and Nesse et al.(2008) criterion. For comparison amongst the gold standard and the other criteria, sensitivity, specificity, predictive values, and likelihood ratio were determined. RESULTS: The frequency of periodontitis ranged from 25.0% to 90.2%. The Bassani et al. (2007) criterion was found to be more sensitive among the studies, and thus more suitable for diagnostic screening studies. Gomes-Filho et al.(2018), Albandar et al. (2007), López et al. (2002), and Nesse et al. (2008) criteria were considered more specific, which makes them more useful for studies of periodontitis with the aim of using diagnosis for confirmation of disease. CONCLUSIONS: A variation in the occurrence of periodontitis was observed. The criterion must be chosen according to the research aims and population characteristics.

Exclusive breast-feeding is associated with reduced pacifier sucking in children: Breast-feeding and pacifier-sucking habit.

BACKGROUND: Studies suggest that when children do not achieve the emotional satiety and adequate stimulus provided by breast-feeding, they exhibit sucking behaviors. This study aimed to estimate the association from 4 through 6 months of exclusive breast-feeding (EB) postpartum and pacifier-sucking behavior at 12 months of life. METHODS: A cohort study was conducted with 1,037 infants, born alive and monitored up to 12 months. At 4 and 6 months after birth, the children were classified according to the type of breast-feeding they had received: exclusive, predominant, complementary, or none. The prevalence of pacifier-sucking behavior was calculated, and the association between the 2 events was estimated. Mothers' socioeconomic-demographic characteristics, delivery features, and prenatal care, as well as the biological characteristics of the children, were determined. Relative risk (RR) and 95% confidence intervals (95% CI) were calculated. RESULTS: In comparison with EB infants, the RR of pacifier-sucking behavior at 12 months of life was higher in children receiving complementary breast-feeding or no breast-feeding for both 4 months (RRadjusted, 1.68 [95% CI, 1.39 to 2.02] and RRadjusted, 2.67 [95% CI, 2.24 to 3.17], respectively) and 6 months (RRadjusted, 1.43 [95% CI, 1.03 to 2.00] and RRadjusted, 3.30 [95% CI, 2.40 to 4.54], respectively). CONCLUSIONS AND PRACTICAL IMPLICATIONS: EB for 6 months postpartum is associated with reduced pacifier-sucking behavior, adjusted for maternal color, number of prenatal consultations, and family income. Promotion of EB may reduce the use of pacifiers and their potential deleterious effects on oral health. Dental health care professionals should consider discussing the importance of breast-feeding with their patients with regard to the possible development of sucking habits in their children.
