Assessment of Oral Conditions and Quality of Life in Morbid Obese and Normal Weight Individuals: A Cross-Sectional Study

The relationship between obesity and oral-health status in North African adults: A comparative study

INTRODUCTION

The strength of the association between obesity and oral health is still indecisive.

OBJECTIVE

The objectives of the study were to compare some oral-health data between two groups involving obese (OG) and normal weight (NWG) participants and determine the influencing factors of the periodontal probing depth (PPD).

METHODS

This was a cross-sectional study including 67 Tunisian adults [OG (n = 33, body mass index (BMI) > 30 kg/m2 ), NWG (n = 34, BMI: 18.5-25.0 kg/m2 )]. The plaque level was recorded using the plaque index (PI). Gingival index (GI) was used to evaluate gingival inflammation. The depths of the sulci/pockets were probed using a periodontal probe. Stimulated saliva was collected for 5 min, and salivary flow rate (SFR) was determined. Salivary baseline pH (SBpH) was measured. A multivariable regression analysis was performed between PPD and some independent variables [i.e. obesity status, age, sex, socioeconomic status, systemic diseases and PI data].

RESULTS

The OG and NWG were age- and sex-matched and included comparable percentages of participants with systemic diseases (27.3 vs. 29.4%, respectively). The OG included a higher percentage of participants having a low socioeconomic status (87.9 vs. 64.7%, respectively). Compared with the NWG, the OG: (i) had comparable values of daily toothbrushing frequency, PI, GI and tooth mobility, (ii) included comparable percentages of irregular brushers, of participants with periodontitis, PI classes [0-1]and [1-2]; and GI classes [0-1], [1-2] and [2, 3]; (iii) had a higher PPD (2.02 ± 0.41 vs. 2.35 ± 0.22 mm, respectively), (iv) had lower SBpH (7.59 ± 0.21 vs. 7.45 ± 0.22, respectively) and SFR (1.98 ± 0.28 vs. 1.60 ± 0.32 mL/mn, respectively) and (v) included a higher percentage of participants having a PI class [2, 3] (67.6 vs. 87.9%, respectively). The multivariable regression analysis revealed that only obesity status, age and PI classes influenced the PPD, altogether explained 29.62% of the PPD variance.

CONCLUSION

Obesity poses a risk for oral health, and obese adults had altered PPD and lower BSpH and SFR. Dentists should make obese patients aware of the health risks of obesity in an attempt to reduce the potential oral complications associated with this epidemic.

Salivary Adiponectin and Albumin Levels on the Gingival Conditions of Patients Undergoing Bariatric Surgery: A Cohort Study

This study analyzed the salivary proteomics, adiponectin and albumin, related to weight loss and periodontitis in patients undergoing bariatric surgery. This study included fourteen patients with morbid obesity (body mass index, BMI > 40 kg/m²) who underwent bariatric surgery Roux-en-Y gastric bypass (RYGB) in System Health Public in Brazil. Data on demographic and anthropometric measures were extracted from medical records preoperatively and 6 and 12 months post-surgery. The variables assessed were: probing pocket depth (PPD), clinical attachment loss (CAL), bleeding on probing (BOP), and stimulated whole-mouth saliva. In this study, saliva samples were analyzed by electrophoresis and immunoblotting. The ELISA kit was used to measure the MMP8 levels to determine potential markers for obesity. Adiponectin and albumin levels were also evaluated. Weight loss was associated with significant changes in patients' periodontal clinical data. Although 7 out of 10 periodontal patients showed an increase in salivary adiponectin levels after root planning treatment, when analyzed by Western blotting, the increase was not statistically significant (21.1 ± 4.8 to 26.3 ± 9.4 arbitrary units, p > 0.99). There was no correlation between albumin levels and salivary adiponectin pre-surgery, nor 6 months or 12 months after surgery. Weight loss was not improved by low-grade inflammation in bariatric patients, since albumin levels were similar between periods. Periodontitis is an inflammatory disease that is modulated by several factors, among which adiponectin plays an important role for the treatment of periodontal disease.

Increased Oral Dryness and Negative Oral Health-Related Quality of Life in Older People with Overweight or Obesity

This cross-sectional study was to evaluate the association between the oral health-related quality of life (OHRQoL) of older Thai people with obesity and oral health indicators. General and oral conditions were assessed. Oral dryness was determined using the Xerostomia Inventory-11 (XI-11) and clinical oral dryness score (CODS). OHRQoL was evaluated by the oral health impact profile (OHIP-14). Participants were aged 60-86 years; 73 (59.3%) were overweight or obese, and 50 (40.7%) were normal weight. Older patients with obesity had almost four times the rate of hypertension (OR = 3.59; 95%CI:1.34-9.60; p = 0.002), more missing teeth (p = 0.025), and higher CODS (p = 0.014) than those without obesity. The total XI-11 scores were positively associated with the total CODS, after adjusting for BMI (r = 0.267, p = 0.003). Those with obesity had almost three times the tendency for a negative OHRQoL compared with the non-obese (OR = 2.73; 95%CI:1.12-6.71; p = 0.04). After adjusting for all related factors, the chances of predicting an OHIP-14 score of four based on obesity and total XI-11 score were 4.42 (95%CI:1.57-12.47; p = 0.005) and 1.11 (95%CI:1.02-1.20; p = 0.013), respectively. Obesity had an increasingly undesirable negative impact on the OHRQoL of older Thai people and was influenced by BMI and oral dryness.

The Impacts of Ramadan Intermittent Fasting on Saliva Flow-Rate and Metabolic Data: A Systematic Review

The aim of this systematic review was to report the impacts of Ramadan intermittent fasting (RIF) on salivary flow-rate (SFR) and metabolic parameters. A thorough literature search was carried out using the databases PubMed and Scopus from their inception up to 15 July 2021. The Boolean connectors used in PubMed were (Saliva [Mesh] AND Fasting [Mesh]). The same keywords were used in Scopus. Inclusion criteria were defined using PICOS. The research included all original studies involving “healthy” adults and published in English. Methodological quality assessment was performed utilizing the Joanna Briggs Institute Critical Appraisal Tool, which allows attributing scores from 1 to 11 to the selected studies. Two authors carried out the literature search, study selection, and data extraction. Differences on issues were resolved by a third author if necessary. The systematic review protocol was registered within the “Open Science Framework” (Doi: 10.17605/OSF.IO/DE7BH). Six articles met the inclusion criteria. All studies were heterogeneous and had a high score of bias and several methodological differences. The following parameters were collected: SFR, melatonin, cortisol, glucose, immunoglobulin A (IgA), uric-acid, alkaline phosphatase (ALP), and aspartate aminotransferase (AST). The SFR decreased by 10% during Ramadan in fasting subjects. The circadian pattern of melatonin remained unchanged during Ramadan, but melatonin levels dropped significantly from baseline. The salivary cortisol levels were unchanged or increased during Ramadan. The salivary glucose levels were decreased. ALP increased significantly, whilst uric-acid and AST decreased significantly. Salivary IgA decreased during the last week of Ramadan. To conclude, there is a trend toward a decrease in SFR and the content of the majority of the biomarkers investigated, with the exception of ALP and uric-acid. These changes cannot be easily attributed to any single factor (hydration status, dietary habits, physical activity, or hygiene habits).

Association between clinical measures of gingival inflammation and obesity in adults: systematic review and meta-analyses

OBJECTIVE

This study aimed to systematically review the literature about the association between clinical measures of gingival inflammation and obesity in adults.

MATERIAL AND METHODS

Searches for studies were performed in five databases (Medline-PubMed, Scopus, Web of Science, Cochrane Library, and Embase) to compile studies of any design that evaluated the association between clinical measures of gingival inflammation and obesity in adults. Selection of studies, data extraction and risk of bias analysis were performed independently by two reviewers, and a third researcher was involved to resolve disagreements. Meta-analyses were performed for measures of gingival inflammation as compared to body mass index (BMI). Independent analyses were performed for studies involving periodontitis, gingivitis, and population-based/studies that did not provide a periodontal diagnosis. Standard mean deviation (SMD) and its 95% confidence interval (95%CI) were estimated.

RESULTS

Ninety studies were included (cross-sectional/clinical trials [n=82], case-control [n=3], cohorts [n=5]). Most of the studies demonstrated no significant difference in the measures of gingival inflammation regardless of the comparison performed. However, meta-analysis showed that among individuals with periodontitis, significantly higher levels of gingival inflammation are observed in those with obesity (n of individuals=240) when compared to those who were not obese (n of individuals=574) (SMD:0.26; 95%CI:0.07-0.44). When considering population-based/those studies that did not provide periodontal diagnosis, significantly higher measures of gingival inflammation were observed in the groups with higher BMI.

CONCLUSIONS

Within the limitations of the present study, it was concluded that higher measures of gingival inflammation may be expected for those with higher BMI.

CLINICAL RELEVANCE

Clinicians must be aware that higher measures of gingival inflammation may be expected for individuals with higher BMI. However, there is a necessity for further longitudinal studies regarding the association between obesity and gingival inflammation.

Salivary pH and oral health of Brazilian para-athletes: Saliva and oral health of para-athletes

AIMS

This study aimed to investigate the association of the salivary pH and parameters of oral health in Brazilian para-athletes.

METHODS AND RESULTS

The sample was composed of 271 Brazilian para-athletes (147 athletics, 61 powerlifting, and 63 swimming); mean age was 31.2 ± 11.7 years. Data collected during anamnesis, clinical examination, and saliva collection revealed that salivary pH was different among sports (p = .01) and tends to decrease as age and body mass index (BMI) increase (p = .026, .027, respectively). The mean decay missing filled teeth was 8.8 (±0.57), but there is no correlation with salivary pH (R²  = -0.0852; CI 95%, -0.215-0.047; p = .194) as habits of grinding, clenching teeth, or bruxism was not associated with salivary pH (p = .317, .932, and .444, respectively). Regarding breathing, para-athletes that have buccal breathing had significantly higher salivary pH (p = .04). This data were confirmed by multiple logistic regression (p = .05). Open bite, lip seal, geographic or fissured tongue also were not associated with variation of salivary pH (p > .05).

CONCLUSIONS

This study provided evidence of an association between salivary pH with age, BMI, type of breathing, and type of sport practiced by the para-athletes.

ASSESSMENT OF ALVEOLAR BONE PATTERN IN OBESE AND NON-OBESE WOMEN, BEFORE AND AFTER BARIATRIC SURGERY: A PROSPECTIVE COHORT STUDY

BACKGROUND

Right and left periapical radiographs in A eutrophic example of normal bone level; in B of morbidly obese before bariatric surgery, presenting bone loss; and in morbidly obese C after six months of the operation presenting great bone loss. Bariatric surgery may have a negative impact on oral bone structure.

AIM

To verify the alveolar bone pattern through radiomorphometric indices of panoramic radiography and linear measurements performed in periapical radiographs in eutrophic and morbidly obese patients before and after bariatric surgery.

METHODS

The sample consisted of 31 women aged 20-35 years old, divided into two groups: obese group (GO-obese grade III) and control group (GC-eutrophic). Twenty eutrophic and 11 obese morbidities were evaluated in the pre and postoperative bariatric surgery (six months). Radiomorphometric and plaque indices were evaluated at T0 (baseline) and T1 (six months) times, in both groups. In the radiographic analysis the trabecular pattern through the Lindh visual ladder and the bone loss were evaluated by calculating the distance from the cement-enamel junction to the bone crest in periapical radiographs. Panoramic radiographs were used to measure the mandibular cortical index (ICM), mentonian index (IM) and panoramic mandibular index (MPI), in addition to the Turesky plate index.

RESULTS

There was a significant loss of bone in T1 in patients submitted to bariatric surgery, when compared to eutrophic patients (p<0.05). The trabecular pattern became sparser after surgery with a visual difference. The plate index showed a slight improvement after surgery and the eutrophic maintained similar values over time.

CONCLUSION

The standard alveolar bone presents greater bone loss in obese patients and worsens this standard after bariatric surgery when compared to eutrophic patients. The same happens with the trabecular pattern that becomes sparser after bariatric surgery.

Dentist-Patient Communication of Treatment Outcomes in Periodontal Practice: A Need for Dental Patient-Reported Outcomes

Periodontal practice has made tremendous progress toward evidence-based treatment over the past decade. Importantly, a new classification scheme for periodontal and peri-implant treatments has recently been devised that is incorporating current evidence and enabling patient-specific periodontal care. However, this important progress can be further accelerated with the availability of patient-perceived outcomes of periodontal and implant interventions. The majority of existing clinical studies assess treatment effects based on clinician-measured surrogate outcomes, such as probing depth and attachment levels which are easily communicated to or perceived by dental patients. As dental patient-reported outcomes (dPROs) gain momentum in dental practice, our understanding of the true outcome of dental therapies is vastly increasing. In periodontal research in particular, the utilization of dPROs has clearly demonstrated that periodontal disease contributes to an individual's burden of disease in a substantial manner. Correspondingly, disease treatment interventions seem to lead to varying levels of patient-perceived improvements. The present editorial aims to highlight the importance of patient communication of treatment outcomes in periodontal and implant research and to review the information on available measures for capturing dPROs.

Autologous platelet-rich fibrin stimulates canine periodontal regeneration

Platelet-rich fibrin (PRF) provides a scaffold for cell migration and growth factors for promoting wound healing and tissue regeneration. Here, we report using PRF in periodontal healing after open flap debridement (OFD) in canine periodontitis. A split-mouth design was performed in twenty dogs. Forty periodontitis surgical sites were randomly categorized into 2 groups; OFD alone and OFD with PRF treatment. Clinical parameters of periodontal pocket depth, gingival index, and the cemento-enamel junction-alveolar bone levels/root length ratio were improved in the OFD + PRF group. The OFD + PRF group also demonstrated a dramatically decreased inflammatory score compared with the OFD group. Collagen accumulation was improved in the OFD + PRF group at later time points compared with baseline. PRF application also significantly reduced inflammatory cytokine expression (TNFA and IL1B), and promoted the expression of collagen production-related genes (COL1A1, COL3A1, and TIMP1) and growth factors (PDGFB, TGFB1, and VEGFA). These findings suggest that PRF combined with OFD provides a new strategy to enhance the overall improvement of canine periodontitis treatment outcomes, especially in terms of inflammation and soft tissue healing. Therefore, PRF use in treating periodontitis could play an important role as a regenerative material to improve canine periodontitis treatment.

Baseline Pro-inflammatory Diet Is Inversely Associated with Change in Weight and Body Fat 6 Months Following-up to Bariatric Surgery

OBJECTIVE

To evaluate whether the baseline Dietary Inflammatory Index (DII®) was associated with weight loss and body composition change after bariatric surgery.

METHODOLOGY

This longitudinal study included 132 women with obesity (BMI ≥ 35 kg/m², 43.0 ± 9.7 years), followed up for 6 months after bariatric surgery. The DII® was calculated from dietary data collected using 24-h dietary recall interviews. Anthropometric variables, socio demographic variables, health-related habits, history of disease, as well as gastrointestinal symptoms, both in the preoperative period (baseline) and 6 months after bariatric surgery were collected from the patients' medical records.

RESULTS

Individuals with a more pro-inflammatory diet (DII > 0.35 median value) preoperatively experienced smaller weight loss (- 22.7% vs. - 25.3%, p = 0.02) and fat mass loss (- 31.9 vs. - 36.2%, p = 0.026), with no difference in lean mass (p = 0.14). In a linear regression model, the baseline DII score was negatively associated with percentage change in weight and fat mass and positively associated with weight and fat mass in the sixth month after surgery. In addition, a pro-inflammatory baseline DII score was correlated with a lower intake of fruit (r = - 0.26, p = 0.006), vegetables (r = - 0.47, p = 0.001), and legumes (r = - 0.21, p = 0.003) in the postoperative period.

CONCLUSION

In this longitudinal study, a pro-inflammatory diet at baseline was associated with smaller reductions in weight and body fat and poorer dietary quality (reduced consumption of fruits, vegetables, and legumes) 6 months after bariatric surgery.

DENTAL WEAR AND TOOTH LOSS IN MORBID OBESE PATIENTS AFTER BARIATRIC SURGERY

BACKGROUND

Obesity and its surgical treatment have been related with oral diseases. Aim: To evaluate and compare dental wear and dental loss in eutrophic and morbidly obese patients submitted to Roux-en-Y gastric bypass.

METHOD

Observational and analytical study with gender and age matching. The sample consisted of 240 patients, divided into four groups: eutrophic (GC=60), morbidly obese (GO=60), operated with up to 24 months (G24=60) and operated on for more than 36 months (G36=60). The following variables were analyzed: race, schooling, economic class, hypertension, diabetes, triglycerides, cholesterol, BMI, weight loss, waist-hip ratio, smoking, alcoholism, tooth loss and tooth wear.

RESULTS

GO presented lower economic class (p=0.012), hypertension (p<0.001), diabetes (p<0.001), cholesterol (p=0.001), BMI (p<0.001), waist-hip ratio (p<0.001) and percentage of weight loss percent (p<0.001) than groups G24 and G36. Dental wear was higher among the II and V sextants.

CONCLUSION

Individuals submitted to Roux-en-Y gastric bypass, regardless of the surgery period, presented more dental wear on the incisal/occlusal surfaces, and the anterior teeth were the most affected. Dental wear was associated with age and number of missing teeth.

Body mass index and periodontal health status among young Saudi adults: a cross-sectional study

BACKGROUND

Obesity has been suggested as a risk factor for periodontal disease. Despite the high prevalence of obesity and over-weight among Saudi population, no study has assessed whether there is an association between periodontal health status and body mass index (BMI).

OBJECTIVES

Assess the association between BMI and other variables with periodontal health status among young Saudi adults.

DESIGN

Analytical, hospital-based cross-sectional study.

SETTING

University dental hospital, Riyadh.

PATIENTS AND METHODS

All dental students aged 21-35 years who met inclusion criteria were invited to participate in the study. Periodontal health status was assessed by the plaque index (PI), gingival index (GI) and community periodontal index (CPI) scores. Biometric measurements included weight, height and BMI. Multiple logistic regression was used to assess the association of independent variables with periodontal disease (CPI>2 vs CPI ≤2) and multiple linear regression models to assess associations with PI and GI.

MAIN OUTCOME MEASURES

Periodontal health by BMI and other variables.

SAMPLE SIZE

308.

RESULTS

Of 700 participants invited, 380 participated for a response rate of 54.2%. Slightly more than half of the obese subjects 54 (52%) did not brush their teeth regularly. The mean (standard deviation) PI and GI scores were significantly higher among the obese (PI score: 1.54 [0.45]); GI score: 1.52 [0.51]) and overweight (PI score: 1.36 [0.47]) and (GI score: 1.42 [0.57]) subjects when compared with subjects with normal weight (PI score: 1.27 [0.51]); (GI score: 1.31 [0.48]); ( P<.05). No significant differences were seen between BMI groups in CPI scores. There were also no significant differences in the mean number and percentage of sextants between different BMI groups. The only signficant factor for periodontal disease in the multivariable analysis was toothbrushing.

CONCLUSION

The present study shows a significant positive correlation between BMI and PI and GI scores. However, no statistically significant association was found between BMI and periodontal health status.

LIMITATION

Cross-sectional, so not possible to assess the association of oral health and BMI over time.

CONFLICT OF INTEREST

None.

Impact of the halitosis on QoL in overweight and obese patients: Based on six years of experience in two centers in sulaimani governorate, Kurdistan Region/Iraq, and case series study

BACKGROUND/OBJECTIVES

The patients who are overweight and obese, are under stress of excess body weight, embarrassed, one may imagine the impact of halitosis on this group of patients, this is an attempt to evaluate this extra impact, and which aspect of quality of life will be affect in the overweight and obese.

SUBJECTS/METHODS

A prospective case series study including 885 overweight or obese patients, they were consulting for advice, diet and or drugs and various bariatric operations. A group of normal weight patients with halitosis, matched in age group and gender were enrolled as a control group for comparison. Patients who have either oral causes of the condition or pseudo halitosis or halite-phobia or were using drugs like phenytoin, cyclosporine or calcium channel blockers, isosorbide di-nitrate, Chloral hydrate, Nitrites and Nitrates, Dimethyl sulphoxide, Disulphiram, cytotoxic agents, Phenothiazine were excluded.

INTERVENTIONS/METHODS

The work conducted over a period of 6 years from February 1st, 2012 to March 1st, 2018. Prospective evaluation of the type and etiology of halitosis was done by using organoleptic measurement, which is not a slandered but evaluated by a group of academic colleagues. The patients were advised to avoid eating odiferous foods for 48 hours before the assessment and both the patient and the examiner should refrain from drinking coffee, tea or juice, smoking and using scented cosmetics before the assessment.

RESULTS

Halitosis in the overweight and obese patients magnifies the negative aspects of quality of life: avoidance, narrow social circle (P Value = 0.3415, 95% confidence interval = 11.43924-29.67085), avoidance of sex by partner (P Value = 0.0143, 95% confidence interval = 04.11537-17.08480), low self-esteem (P Value = 0.0100, 95% confidence interval = 10.66794-28.44776), teasing by others and negative thoughts (P Value = 0.4013, 95% confidence interval = 11.43924-29.67085). While obesity was not a cause of avoidance of to be kissed by partner in obese patients, but was a direct cause for this avoidance in obese patients with halitosis (P Value = 0.0143, 95% confidence interval = 04.11537-17.08480). Halitosis in normal weight patients affects the quality of life remarkably but not to the extent of halitosis in overweight and obese patients, especially social life and self-esteem which will suffer most.

CONCLUSIONS

The quality of life of overweight and obese, especially emotional and social aspects was significantly disturbed by halitosis more than normal weight subjects with halitosis.

Effects of dropping out of dental treatment on the oral health-related quality of life among middle-aged subjects using web research

Objective

The oral health-related quality of life has recently been reported to be a rather important aspect of general health. Dropping out of dental treatment has long been a problem plaguing oral health. However, the relationship between dropout for dental treatment and the oral health-related quality of life is unclear. The purpose of this study was to investigate the oral health-related quality of life in patients who dropped out of dental treatment.

Materials and methods

We conducted a questionnaire-based investigation using web research. The participants were allocated to two groups (dropout group and maintenance group). The dropout group included participants who had stopped visiting their dental office in the past and had not revisited in the last decade. The maintenance group included patients who visited their dental office continually for a regular checkup. We analyzed the General Oral Health Assessment Index (GOHAI) as an indicator of the oral health-related quality of life and assessed the background characteristics of the subjects.

Results

We analyzed 225 people in the dropout group and 236 people in the maintenance group. The score of GOHAI was significantly different between the 2 groups (dropout group:47.07, maintenance:48.97, p = 0.035), and the more frequent dropouts brought the less GOHAI score (p = 0.012). Furthermore, the results of a logistic regression analysis showed that dropping out of dental treatment was significantly associated with the GOHAI score (p = 0.002).

Conclusion

A relationship was demonstrated between the oral health-related quality of life and dental treatment dropout. Furthermore, dental treatment dropout seemed to have negative effects on the oral health-related quality of life.

Prevalence of risk factors for oral diseases in obese patients referred for bariatric surgery

BACKGROUND

Obesity is a risk factor for several chronic diseases, and scientific evidence suggests an association between obesity and oral diseases. In this study, the authors estimated the prevalence of risk factors for caries, dental erosion, and periodontal disease in a group of obese patients referred for bariatric surgery.

METHODS

The authors invited obese patients who were referred for bariatric surgery at a private center for treatment of obesity to participate in this study. The patients answered a questionnaire about their sociodemographic data, general and oral health histories, dietary habits, and oral health care behavior.

RESULTS

The authors evaluated a total of 255 participants; 200 (78.4%) were women, the median (interquartile range) age was 36.0 (30.0-43.0) years, and the median (interquartile range) body mass index was 39.7 (37.6-43.5) kilograms per square meter. The authors observed a high prevalence of risk factors for dental erosion; 78.4% of the participants consumed acidic foods daily, and 92.2% consumed acidic beverages daily. With respect to risk factors for caries, 38.5% of the participants reported high sucrose intake, and 59.6% preferred sweet beverages and foods with sucrose. Almost 13% of the participants reported having or having had dental mobility, and 59.6% reported having or having had gingival bleeding, suggesting a history of periodontal disease.

CONCLUSIONS

Obese patients referred for bariatric surgery are exposed to risks of experiencing oral diseases and should be evaluated by a dentist.

PRACTICAL IMPLICATIONS

Knowing the risk factors for oral diseases in obese patients is important in raising awareness about these risk factors, as well as to prevent complications in the oral cavity.

Comparisons of Fatty Acid Taste Detection Thresholds in People Who Are Lean vs. Overweight or Obese: A Systematic Review and Meta-Analysis

Given the increasing evidence that supports the ability of humans to taste non-esterified fatty acids (NEFA), recent studies have sought to determine if relationships exist between oral sensitivity to NEFA (measured as thresholds), food intake and obesity. Published findings suggest there is either no association or an inverse association. A systematic review and meta-analysis was conducted to determine if differences in fatty acid taste sensitivity or intensity ratings exist between individuals who are lean or obese. A total of 7 studies that reported measurement of taste sensations to non-esterified fatty acids by psychophysical methods (e.g.,studies using model systems rather than foods, detection thresholds as measured by a 3-alternative forced choice ascending methodology were included in the meta-analysis. Two other studies that measured intensity ratings to graded suprathreshold NEFA concentrations were evaluated qualitatively. No significant differences in fatty acid taste thresholds or intensity were observed. Thus, differences in fatty acid taste sensitivity do not appear to precede or result from obesity.

Presence of Serum Ferritin before and after Bariatric Surgery: Analysis in Dentate and Edentulous Patients

Society has changed its own lifestyle, specially its eating habits and physical activities, leading to excessive weight and a sedentary behavior, which has contributed to obesity increase. Bariatric surgery is the most effective treatment to obesity, allowing weight loss and its maintenance. However, it has been related high levels of iron deficiency after surgery. A person's nutritional status might be affected by total or partial tooth loss. The aim of this longitudinal prospective cohort study was to evaluate the levels of serum ferritin before and after bariatric surgery and to identify if there is a relation with tooth loss. The sample was composed of 50 patients selected and assisted at Amaral Carvalho Hospital, located in Jaú city, Brazil. The use and necessity of prosthesis, dental absence or presence, and serum ferritin dosage were evaluated. Student's t test, Univariate analysis, Chi-square and Odds Ratio were adopted (p<0.05). There was no significant difference regarding the serum ferritin levels between dentate and edentulous patients prior to surgery (p = 0.436). After surgery, the serum ferritin levels were higher in edentulous patients (prosthesis users) when compared to the pre-surgical levels, and the post-surgical levels presented significant difference regarding the dentate patients (p = 0.024). It can be concluded that rehabilitated patients in postoperative period showed better levels of serum ferritin after surgical intervention.

MASTICATORY FUNCTION OF OBESE CANDIDATES TO BARIATRIC SURGERY FROM DISTINCT SOCIOECONOMIC CLASSES

Background

Obesity and metabolic syndrome can be labeled as worldwide outbreak; thus, both have led to serious public health problem. Oral health can be worsened by both, obesity and metabolic syndrome. Tooth loss harms masticatory function, essential status to whom will be submitted to bariatric surgery.

Aim

Assess masticatory function of obese candidates to bariatric surgery, who belong to distinct socioeconomic class range, in order to recognize hazard factors and the bias of socioeconomic factor in this context.

Methods

Observational cross-section study, with samples comprised by two groups of patients, with distinct socioeconomic class range, one of them belonging to public health system (SUSG) and the other to private clinic (CPG), candidates to bariatric surgery. Were assessed anthropometric data, comorbidities and medicines usage, blood tests, habits and the number of dental functional units.

Results

The groups SUSG and CPG were homogeneous taking into account gender (p=0,890) and age range (p=0,170). The number of dental functional units was higher in the private group (p<0.001). The impaired masticatory function was rather present among public group (p<0.001) and female gender (p<0,001). Regarded as blood tests, fasting glucose was higher in female in SUSG (p<0,001). The following hazard factors have corroborated to have patients rated as impaired masticatory function: belong to public service (OR: 8.420, p=0.003), higher age (OR: 1.186, p<0.001), female gender (OR: 0.153, p=0.029), diabetes mellitus (OR: 2.545, p=0.045) and smokers (OR: 2.951, p=0.043).

Conclusion

The general health and masticatory function of female SUSG were worse, highlighting the socioeconomic condition as hazard factor.
