[Show abstract][Hide abstract] ABSTRACT: The scope of this study was to conduct a systematic review of the studies on the association between obesity and periodontitis. The methods applied included a literature search strategy and selection of studies using inclusion and exclusion in accordance with the criteria for characteristics of the studies and meta-analysis. The research was conducted in the PubMed, Embase and Lilacs databases through 2010. Selected papers were on studies on humans investigating whether or not obesity is a risk factor for periodontitis. Of the 822 studies identified, 31 studies met the inclusion criteria and were included in this meta-analysis. The risk of periodontitis was associated with obesity (or had a tendency for this) in 25 studies, though it was not associated in 6 studies. The meta-analysis showed a significant association with obesity and periodontitis (OR = 1.30 [95% Confidence Interval (CI), 1.25 - 1.35]) and with mean Body Mass Index (BMI) and periodontal disease (mean difference = 2.75). Obesity was associated with periodontitis, however the risk factors that aggravate these diseases should be better clarified to elucidate the direction of this association. Working with paired samples and avoiding confusion factors may contribute to homogeneity between the studies.
[Show abstract][Hide abstract] ABSTRACT: We evaluate oral health conditions before and after bariatric surgery.
The sample was composed of 59 patients who had undergone Roux-en-Y gastric bypass (RYGB). Salivary flow, periodontal pocket depth and dental wear were evaluated before and after 6 months of surgery. Body mass index (BMI), C-reactive protein (CRP) and glucose levels were obtained from the patient's medical files. A t-test was used for dependent samples.
The mean BMI decreased from 49.31 ± 8.76 to 35.52 ± 8.12 kg/m(2) in 6 months after surgery (P < 0.000). Before surgery, 67% of patients had high levels of CRP and 38% higher blood glucose levels and after surgery there were significant reductions in these levels (P < 0.001). Salivary flow ranged from 0.84 to 0.95 ml/min. There was increased prevalence of periodontal pockets (P = 0.022) and mean pocket depth increased to about 0.5 mm (P < 0.001). The percentage of surfaces with dental wear in dentine was significantly higher after bariatric surgery (P = 0.002), while dental wear in enamel decreased (P = 0.019).
Bariatric surgery may improve systemic conditions. However, it had a negative impact on oral health conditions because of an increase in periodontal disease and dental wear.

[Show abstract][Hide abstract] ABSTRACT: Objective: To evaluate the efficacy of Neem (Azadirachta indica) experimental gel for the prevention of erosive wear on bovine dentin, in vitro. Material and Methods: One hundred dentin blocks were allocated into 5 experimental groups (20 samples each): C (control group, without gel); CG (control group, only base gel); F (fluoride gel, 1.23% NaF; pH 4.1, Dentsply; Brazil); N (Neem gel, 10% neem extract; pH 4.1, manipulation); NF (Neem+fluoride gel, 10% Neem extract and 1.23% NaF; pH 4.1, manipulation). The blocks were stored in artificial saliva for 24 hours. After this, they were submitted to six alternating re- and demineralization cycles. The blocks were analyzed for wear (profilometry). The results were submitted to statistical analysis by ANOVA and Tukey tests (P<0.05). Results: The mean wear (±SD, µm) was shown as follows in groups: C (13.09±0.99), CG (10.60±1.99), F (10.90±1.44), N (12.68±1.13) and NF (10.84±1.65). All gels showed some preventive action when compared with control group. However, significant differences were found only between Neem+fluoride gel and fluoride gel. Conclusion: A single application of a neem-containing fluoride gel reduced dentin erosion, thus it is a possible alternative in reducing dental wear. Further research should investigate the action mechanism and the synergism between them.

[Show abstract][Hide abstract] ABSTRACT: Background: The prevalence and severity of tooth wear and dental erosion is rising in children and there is no consensus about an index to be employed. Aim: To assess the reliability of an epidemiological scoring system dental wear index (DWI) to measure tooth wear and dental erosive wear. Design: An epidemiological cross-sectional survey was conducted to evaluate and compare tooth wear and dental erosion using the dental wear index and erosion wear index (EWI). The study was conducted with randomised samples of 2,371 children aged between 4 years and 12 years selected from the State of São Paulo, Brazil. Records were used for calculating tooth wear and dental erosion; the incisal edge and canine cusp were excluded. Results: As the schoolchildren's ages increased the severity of primary tooth wear increased in canines (P = 0.0001, OR = 0.34) and molars (P = 0.0001, OR = 2.47) and erosion wear increased in incisal/occlusal (P = 0.0001, OR = 5.18) and molars (P = 0.0001, OR = 2.47). There was an increased prevalence of wear in the permanent teeth of older schoolchildren, particularly on the incisal/occlusal surfaces (P = 0.0001, OR = 7.03). Conclusion: The prevalence of tooth wear and dental erosion increased as age increased in children. The epidemiological scoring system Dental Wear Index is able to measure both tooth wear and dental erosive wear. This index should be used to monitor the progression of non-carious lesions and to evaluate the levels of disease in the population.

[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to investigate the association between glucose levels with dental caries and the role of body mass index (BMI) in obesity subjects.
Method: This was a prevalence study and the sample was consisted of 80 morbid obesity patients. The role of body mass index (BMI) and waist/hip ratio (WHR) on diabetes obese patients were evaluated. The ICDAS index was used to assess dental caries and glucose levels were obtained by the patient's medical files. Chi-square and Odds ratio were adopted with significance level at 5%.
Result: The mean age was 38.23 and the mean BMI was 53.6±9.38 kg/m2 between obese individuals. The waist/hip ratio (WHR) showed that 42.50% and 57.50% of patients presented risk and high risk for cardiovascular diseases, respectively. Diabetes was found in 25% of the patients evaluated. ICDAS was divided into initial lesions (IL=76.25%) and cavitated lesions (CL=47.50%). There was no significance between ICDAS and WHR. Diabetes showed significant association with ICDAS (OR=3.74; 95%CI=1.81-7.73; P<0.000) and WHR (OR=0.2464; 95%CI=0.12-0.48; P<0.000).
Conclusion: The waist/hip ratio for high risk of cardiovascular diseases may interfere in the diabetes occurrence and this in dental caries lesions in morbid obesity patients.

[Show abstract][Hide abstract] ABSTRACT: Objective: The aim was to assess dental caries in morbid obese subjects and association with diabetes and quality of life (OHRQoL).
Method: This longitudinal study sample was composed of 40 morbid obese patients who had undergone Roux-en-Y gastric bypass (RYGB). The sample was analyzed before (0M) and after 6 month (6M) of bariatric surgery. The dental caries was measure by International Caries Detection and Assessment System (ICDAS). High values of intra- and inter-examiner agreement were achieved (Kappa > 0.87). Surface-specific caries data were collected and the presence of precavitated "white spot" lesions was recorded at the subject level. Body mass index (BMI) and glucose levels were obtained by the patient's medical files. The subjects answer a questionnaire of quality of life Oral Impacts on Daily Performances (OIDP). Data were analyzed by Pearson’s correlation and paired t test with significance level at 5%.
Result: Cavitated scores (LC) ranged from 0.70±0.86 to 0.35±1.13 (P=0.000) and noncavitated (LI) caries lesions 1.30±2.57 to 0.70±0.86 (P=0.000) in ICDAS codes after 6 months of RYGB, respectively. There were significant difference in both conditions (LI and LC) analyzed by ICDAS before and after surgery (P<0.00). The glucose levels decreased from 110.86±42.28 to 84.06±11.24 mg/dL (P=0.008) after 6 months of surgery, respectively. The majority of the participants replied that they had at least one OIDP impact on daily life in the past 6 months. There was significant association between ICDAS and OIDP impact (P<0.00) in both periods evaluated (0M and 6M).
Conclusion: Diabetes levels were reduced and the dental caries lesions had worsening after bariatric surgery. The presence of dental caries promoted great impact in quality of life of patients before and after surgery. Supported by CNPQ (Proc. 301146/2010-1)

[Show abstract][Hide abstract] ABSTRACT: In published studies, it has been suggested that dental wear is associated with gastroesophageal reflux disease (GERD). This systematic review was carried out to evaluate the association of GERD, dental erosion, and halitosis and to compare the indices adopted in epidemiological surveys. The Medline database (until October, 2011) was searched systematically to identify studies evaluating the prevalence of oral alterations, such as dental erosion and halitosis, in patients with GERD symptoms. Two reviewers analyzed all reports and the selected studies were evaluated according to the quality of evidence, using the validated Newcastle-Ottawa Quality Assessment Scale. Full-text copies of a total of 32 publications were obtained in duplicate. Sixteen publications were identified among the citations in the Bibliographic lists of studies that fulfilled the exclusion/inclusion criteria and quality of evidence. The relationship between dental erosion and GERD patients was significant in only seven studies. According to three studies, halitosis could be one of several extraesophageal symptoms or manifestations in GERD patients. In one study, it was found that the mucosa of GERD patients was significantly more acidic in comparison with that of the control group. This systematic review showed that there is a relationship between GERD and oral diseases (dental erosion and halitosis). The epidemiological surveys used different indices to analyze GERD and dental erosion. Further research could investigate the best method for assessing the two diseases.

[Show abstract][Hide abstract] ABSTRACT: Objective: The almost permanent oral cavity contact with the external environment makes it extremely vulnerable, becoming essential the dentist presence at the worker health team, enabling the accidents prevention, optimizing the performance and improving quality of workers life. This study conducted an epidemiological survey of workers oral health conditions in different counties, extending the findings to the Brazilian reality. Therefore, we selected four regions of Brazilian workers.
Method: We conducted workers oral examination at the enterprise place, collecting data like caries (DMFT), periodontal disease (CPI) and use or need of prostheses. Statistical analysis ANOVA was used to test and so a Spearman correlation (p <0.05).
Result: We found a mean DMFT of 13.2. In relation to periodontal disease, 46.75% had bleeding, 69% had calculus and 25% had periodontal pockets. The prosthesis use was 23.85% and prosthetic rehabilitation necessities was 48.02% regarding Brazilian workers.
Conclusion: We conclude that there is no difference between regions analyzed in this study, however, the Midwest was less affected, and may be associated with regional socio-economic status.
[Show abstract][Hide abstract] ABSTRACT: Objective:
The objective of this study was to identify the prevalence of dental wear and to analyze the relation with salivary flow and vomiting in morbid obese patients.
The oral conditions of 50 morbid obese patients were evaluated by means of Dental Wear index (DWI) and salivary flow. The patients answered a questionnaire about vomiting frequencies. Qui-Square test and Odds ratio were used (P<0.05).
Result: The mean age was 36.7±9.9 year-old of patients and the female were more frequent (90%). The mean BMI was 52.9±9.3 kg/m2. All patients presented at least one tooth with dental wear. The percentage of patients with dental wear in enamel was 8% and 52% in dentine. Fifty- four percent of patients presented reduction of salivary flow (0.76±0.5mL/min). The obese patients with reduction of salivary flow presented more dental wear (P=0.02; OR=0.9). According to the questionnaire, only 7 of obese patients had frequent vomiting, however these patients have no higher prevalence when compared with those who had no vomiting (P=0.585; OR=0.51).
The salivary flow was reduced in morbid obese patients and this reduction was related with the high prevalence of dental wear. Thus, these patients should be followed by dentists to prevent and stabilize the dental wear and salivary flow.
[Show abstract][Hide abstract] ABSTRACT: Objective: Obesity is the major public health problem in view of the high prevalence, difficulty in control and high recurrence rate. Obesity, disease and tooth decay entailed in eating habits have an important common etiological component. The morbid obese bariatric surgery candidates undergo a preparatory process that generates changes in lifestyle. It is suggested that a dietary reeducation involves among other things, control the quality and quantity of food intake, and a proper chewing. The objective of this cross-sectional study was to measure the history of present or past caries morbidly obese patients undergone bariatric surgery at the Hospital Amaral Carvalho in Midwest of São Paulo State, Brazil.
Method: One hundred and six individuals were submitted by clinical examination, using the DMFT index according to criteria recommended by WHO (1997).
Result: Participants had mean DMFT of 16.3, and the components decayed, missing and restored corresponded by 9.0%, 35.8% and 55.2%, respectively. There were no differences in DMFT values between gender (p> 0.05), age (p> 0.05) and educational level (p> 0.05) in this sample.
Conclusion: The mean DMFT of obese adults participating in this study is also found in the National Oral Health Survey (SB Brazil 2010) for individuals in this age group (16.3). However the high percentage of missing teeth impairs chewing and the quality of therefore, digestion and absorption of nutrients, factors that can bring harm to the health of patients undergoing bariatric surgery. In this context, the evaluation of dental status before bariatric surgery is needed to make guidelines on oral health care and indicate the need for dental treatment in order to contribute to the success of bariatric surgery, and a better quality of life.
[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to identify the prevalence of dental caries, periodontal status and evaluated the relation with systemic health changes in morbid obese patients, candidates for bariatric surgery.
Method: The sample consisted of 50 morbid obese patients that were evaluated adopting the International Caries Detection and Assessment System (ICDAS-II), periodontal pocket depth (PD), clinical attachment level (CAL), bleeding (B) and calculus (C), salivary flow (SF),waist circumference status (WC). Blood samples were drawn to determine metabolic status. Chi-square test was used (P<0.05).
Result: It was found ICDAS-II prevalence of 0.83± 0.9, with initial and cavitated lesions (84% and 40%, respectively). In periodontal status the PD was 1.65 ± 0.5, CAL 1.82 ± 0.8, 76% had B and C was observed in 66% of the patients. SF was 0.76 (±0.5), which is considered low. The WC was high for both genders (131.25±16.8cm). Among the patients, 13 were diabetics. The patients with diabetes had high caries lesion prevalence (P=0.001) and worst periodontal status (P=0.041; OR=3.9).
Conclusion: There was high prevalence of early caries lesions and bleeding in morbid obese Brazilian, which could be reduced with preventive measures. The obese patients with diabetes had more probability to developed dental caries and periodontal diseases. Supported by CAPES and CNPQ.
[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to identify the prevalence of dental caries, periodontal conditions, prosthetic status and need and evaluated the relation with systemic health changes in morbid obese patients
Method: The sample of this cross-sectional study consisted of 50 morbid obese patients that were evaluated adopting Dental Caries index (DMFT), Community Periodontal Index (CPI), Prosthetic status and need, Body Mass Index (BMI) and Salivary flow. Blood samples were drawn to determine metabolic status. Chi-square test was used (P<0.05).
Result: The DMFT was 14.68 and 30% of the individuals had caries. In CPI 38% had calculus, 30% pockets (≥ 4.0 mm) and bleeding in 10% of them. In relation to the Prosthetic status 20% used prosthesis (mandible and maxillary arches), 42% need prosthesis in mandible and 22% maxillary arch. The BMI was 52.92, showing severe obesity. The salivary flow was considered low (0.76mL/min). Thirteen patients were diabetics (26%). The diabetics patients had high caries prevalence (P=0.125; OR= 0.36) and worst CPI (P=0.041; OR=3.9).
Conclusion: Morbid obese patients did not showed good oral conditions; however the diabetic individuals had worse conditions, especially the periodontal diseases.
[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to identify the incidence of dental caries and dental wear in undergone bariatric patients.
Method: The 55 morbid obese (PRE) patients were evaluated and followed up after 3 (3M= 28 patients), 6 (6M:=18 patients) and 12 (12M= 9 patients) months. It was adopted the Dental Caries index (DMFT) and Dental Wear index (DWI). The patients answered a questionnaire about vomiting frequencies. ANOVA test was used (P<0.05).
Result: The DMFT for the obese was 16.2 ± 5.3, 3M was 18.6 ± 4.0, 6M was 18.1 ± 4.8 and 12M was 21.3 ± 2.74 (P>0.05). The incidence of dental wear increased after bariatric surgery was found, being significant difference after 6 months (p=0.006). The severity of dental wear also increased after bariatric surgery. The percentage of dental wear in dentine was: PRE=83%; 3M=85.5%; 6M=88.9%; 12M=100%). However, there was no significant difference among periods (P>0.05). According to the questionnaire, only 11.9% of obese patients had frequent vomiting, the percentage increased to 43.9%, 33.3% and 55.6% to 3M, 6M and 12M, respectively.
Conclusion: The increase of dental caries and dental wear after bariatric surgery could be related to the association of the stomach reduction and inappropriate chewing. These patients should be followed by dentists to restore and maintain good oral health, before and after bariatric surgery(Supported by CNPq).
[Show abstract][Hide abstract] ABSTRACT: Objective: This in situ study evaluated the protective effect of the euclea natalensis gel in dentin erosion (EROS) and erosion+abrasion (EROS+ABRAS).
Method: Ten volunteers wore intraoral palatal appliances with human dentin specimens subjected to EROS or EROS+toothbrushing abrasion performed 30 min after erosion (ERO+ABRAS). Samples were recessed in palatal mouth appliances and worn day and night except during meals. During 2 experimental 5-day crossover phases, the specimens per volunteer received or not a thin layer of the gel for 5 min and it was carefully removed with a cotton swab. Extraorally, the erosive (5 min, cola drink) and abrasive challenges (30 min, toothbrushing) for 4x/day. Dentin tissue loss was measured profilometrically (μm). ANOVA and Tukey’s test were used (P<0.05).
Result: The euclea natalensis gel reduced the dentin wear significantly for all conditions (EROS=5,81±1,00; EROS+ABRAS=6,16±1,00) compared to control (EROS=13,85±9,60; EROS+ABRAS=13,77±7,73). Experimental gel provoked dentin loss minor (P<0.05) in both conditions EROS or EROS+ABRAS, which in turn did not significantly differ from each other.
Conclusion: It may be concluded that the euclea natalensis gel is able to reduce the dentin wear under erosive/abrasive conditions, being a good option to clinical preventive measure. Further research has to confirm this promising result in the clinical situation. (Supported by CNPq and FAPESP – 2010/09951-0)
[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to evaluate the effect of an experimental gel containing euclea natalensis on dentin permeability
Method: : Thirty-six dentin discs, 1-mm-thick dentin disks were prepared from the coronal dentin of extracted sound human molars were divided into three groups (n=10). The groups corresponded to the following experimental materials: EN- Euclea natalensis extract gel, F-1.23% fluoride gel; C- control gel, applied to the dentin under the following conditions: after 37% phosphoric acid and before 6% citric acid. The hydraulic conductance of each condition was determined four times using Flodec. ANOVA and Tukey’s test were used (P<0.05)
Result: In all conditions, the EN and F groups differed significantly from C for reducing dentin permeability, except in the presence of smear layer (P<0.05). The effectiveness in reducing dentin permeability did not differ significantly between EN and F gels after acid challenge (P>0.05)
Conclusion: The results suggest that the euclea natalensis gel can interfere in the reduction of dentin permeability, even when subjected to acids challenges. This plant seems be an important preventive measure for application in dentin sensitivity.

[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to evaluate oral changes, such as dental caries, periodontal disease, salivary flow and the impact of these alterations in quality of life in bariatric patients.
Method: The sample consisted of 55 morbid obese patients (PRE) who underwent bariatric surgery and were followed up after 3 (3M: 28 patients), 6 (6M: 18 patients) and 12 (12M: 9 patients) months. Indices for evaluating oral conditions were: ICDAS II, CPI and salivary flow. BAROS and OIDP questionnaire were used to assess the impact of oral health on quality of life. ANOVA and Friedman test were used (P<0.05).
Result: ICDAS II was 0.3±0.4, 0.1±0.2, 0.1±0.1 and 1.7±2.2 for the PRE, 3M, 6M and 12M, respectively. There were significant differences between the PRE, 3M and 6M when compared with 12M (p=0.000). Periodontal conditions appeared to worsen after bariatric surgery (periodontal pocket – Pre=49.1%, 3M=60.7%, 6M=38.9%, 12M=77%), however no difference significant between the periods was found (p= 0.245). Salivary flow was 0.8 ± 0.4, 0.9 ± 0.4, 1.1 ± 0.5 and 0.7 ± 0.5 for PRE, 3M, 6M and 12M, respectively. The quality of life seemed good after bariatric surgery according to BAROS. The impact of oral health on quality of life decreased gradually after bariatric surgery (OIDP), and the criterion of masticatory capacity was the most severe.
Conclusion: The pre-existing oral problems, such as dental caries and periodontal diseases, may increase their severity after bariatric surgery. However, this change in oral health status did not influence the quality of life. (Supported by CNPq).
[Show abstract][Hide abstract] ABSTRACT: Objective: This study aimed to analyze the influence of different methods of storage of human enamel, in order to maintain their properties and structural integrity.
Method: The sample consisted of 54 molars, assigned from a Human Teeth Bank, which were distributed randomly into three groups according to the method of processing employed: control - distilled water, thymol 0.1% and sodium azide 0.02%. The tests performed were laser fluorescence, surface microhardness and profilometry analysis (0, 15 and 30 days). Statistical analysis was performed by ANOVA and Tukey (P <0.05).
Result: In the laser fluorescence test thymol solution at 0.1% proved to be more viable in maintaining the integrity of the dental organ, since it did not show significant variations in the laser fluorescence values among the analyzed periods (P> 0.05). The surface microhardness analysis showed the tooth structure loss in all methods used, and sodium azide led to a smaller tooth tissue loss. The profilometry analysis showed loss of mass in all groups whereas sodium azide showed the greatest loss.
Conclusion: Among the processing methods analyzed none was able to maintenance of the structural integrity of the human enamel. Thymol solution 0.1% seems to be the storage method most accepted for studies on human enamel. (Supported by CAPES)
[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of the study was to identify the prevalence of dental wear in schoolchildren of 7-10 years and to analyze the correlations with nutritional conditions and quality of life.
Method: A cross-sectional survey with sample comprised 372 children of both genders. An assessment of dental wear index (DWI) was made according to diagnostic criteria proposed by Sales Peres (2008). Body mass index (BMI)(kg/m2) used for nutritional conditions. For nutritional conditions data were divided into gender and age, as the BMI changes with these conditions. A modified version of The Child Oral Impacts on Daily Performances (Child-OIDP) was used for quality of life. The data analysis were descriptive statistics, univariate and Stepwise logistic regression (P<0.05).
Result: The prevalence of dental wear showed great in molars (69.16%) followed by canines (68.35%), in primary dentition. In nutritional conditions, the malnutrition and the normal BMI for male (31.44%; 36.60%) and female (30.20%; 36.63%) were found, respectively. It was considered a satisfactory condition when 51% of positive responses indicated satisfaction with the conditions presented in the questionnaire. For oral health 55.3% had a satisfactory self reported, 86.24% good to be functional, 84.41% a social emotional well-being, 93.37% a good school environment and 78.66% having a good self esteem. There was an association between BMI and tooth wear in primary dentition (P<0.05). The relationship between tooth wear and quality of life in this age group showed no statistically significant correlation.
Conclusion: Malnutrition schoolchildren were more likely to have dental wear in primary teeth while obese showed more occurrence of wear in the permanent dentition. Quality of life was not related to dental wear in children.
[Show abstract][Hide abstract] ABSTRACT: Objective: The aim of this study was to investigate the association between glucose levels with periodontal status and the presence of periodontopathogenic bacteria in morbidly obese individuals.
Methods: Ninety one morbid obese patients in preoperative care for obesity surgery were evaluated. A clinical exam was performed to evaluate bleeding on probing, presence of calculus, probing pocket depth and clinical attachment levels. The presence of Porphyromonas gingivalis and Treponema Denticola DNA from gingival crevicular fluid was analyzed by Quantification Real-time Polymerase Chain Reaction (q-PCR). Body Mass Index (BMI) and glucose levels were obtained by the patient's medical files. Data were analyzed by Student t test and Pearson´s correlation with significance level at 5%.
Results: The mean age was 38 year-old. It was observed that 36% of obese presented high glucose levels (>99mg/dL). The mean BMI was 50.9±11.2 kg/m2 among non-diabetic and 48.9±8.3 kg/m2 among diabetic individuals. Diabetic patients presented greater probing pocket depth, clinical attachment levels than non-diabetic and sites with periodontal pocket from 4 to 5 mm (P=0.011; 0.009 and 0.000, respectively). There was positive correlation between amount of T. denticola and glucose level (r= 0,389; P= 0,021). Mean glucose level was higher in patients with presence of P.gingivalis, however no significant difference was found.
Conclusions: Diabetic individuals showed worse periodontal status and higher amount of bacteria. Morbid obese patients have poor periodontal status and the high glucose levels in these patients increase the risk factors for periodontal inflammation. Supported by FAPESP (2008/05798-2; 2008/00240-3)
