Abstract Introduction The investigation of peri-implant diseases risk indicators helps to prevent and target treatment techniques. Objective The aim of this cross-sectional study was to determine the occurrence of peri-implantitis and its potential risk indicator factors, besides to assess the long-term success and survival rates of dental implants after 8 to 10 years of function. Material and method For this, fifty individuals who had received their implant-supported rehabilitation between 2003 and 2005 were included. Data regarding demographics, medical and dental history were collected and a complete clinical examination was performed. Multivariate analysis was used to identify potential risk indicator factors related to the occurrence of peri-implantitis. Overall, 211 implants had been placed; 197 were in function, 9 were still submerged, and 5 had been lost. Result Success and survival rates were 81.5% and 97.6%, respectively. Peri-implant mucositis affected 77.1% of subjects and 52.3% of implants. Peri-implantitis was diagnosed in 14 individuals (29.2%) and 25 implants (12.7%). Subjects with osteoporosis (OR = 2.84) and generalized bleeding on probing (OR = 8.03) were significantly associated with higher odds of peri-implantitis. At the implant level, visible plaque (OR = 4.45) and deep probing depths (OR = 4.47) were significantly associated with peri-implantitis. Conclusion Through these results, our study suggests that osteoporosis and generalized periodontal/peri-implant mucosa inflammation increase the likelihood of peri-implantitis.

Abstract Introduction Extraoral strength is the most common strategy to correct Angle Class II malocclusion, restricting and redirecting the maxillary growth. Objective To evaluate the skeletal changes resulting from the use of headgear, with cervical and parietal anchorages, associated with a full fixed orthodontic appliance, in growing patients with Class II malocclusion (Angle) treated in the clinic of an orthodontic training center. Material and method The ages at the beginning and end of the treatment, anchorage type, and the values of some cephalometric variables were obtained from the clinical files. After applying the inclusion and exclusion criteria, 56 patient files were selected. Then, the sample was divided into two groups, according to the anchorage type: cervical (n=30) and parietal (n=26). The differences between the initial (T1) and final (T2) values of cephalometric measurements SNA, SNB, ANB, AO-BO, GoGn.SN and LHF (percentage of lower facial height to total facial height) were evaluated in both groups. Result Significant differences between T1 and T2 were found relative to SNB and ANB variables in both groups. The AO-BO variable presented a statistically significant difference only in the cervical group. The remaining variables did not show significant differences between T1 and T2. Conclusion The skeletal changes resulting from the use of cervical or parietal anchorage were very similar. There was a decrease in the sagittal discrepancy between the maxillary bones due to forward displacement of the mandible, without significant vertical changes.

Abstract Introduction Orofacial pain is a critical TMD symptom that can influence physical and social capacity. Objective To evaluate the association of temporomandibular disorders (TMD) symptoms with affective relationships and demographic variables in young adults. Material and method A cross-sectional study involving 395 young adults was developed. Diagnostic Criteria for TMD, anxiety, and depression were collected from questionnaires. The Dental Health Component of the Index of Orthodontic Treatment Need measures the orthodontic treatment need. Questionnaires also contained questions related to the previous orthodontic treatment. Logistic regression models were adjusted, estimating crude odds ratio with the 95% confidence intervals. The variables with p<0.20 in the analyses were assessed in a multiple logistic regression model, remaining with p≤0.10. Result There was no significant association of TMD symptoms with sex, age, medication use for pain, previous orthodontic treatment, orthodontic treatment need, anxiety, and depression (p>0.05). Individuals without an affective relationship are 1.78 (95%CI: 0.99-3.17) times more likely to report TMD symptoms. Conclusion Affective relationships showed an association with TMD symptoms in young adults.

Abstract Introduction Changes caused by the rigidity of Parkinson’s Disease (PD) can affect the mandibular musculature. However, few studies have been published about its impact on the oral opening. Objective To analyze the relationship of the vertical extension of the oral opening with muscular rigidity and sociodemographic factors of the elderly with PD. Material and method This is a cross-sectional, quantitative study that collected data from a primary study conducted at the Hospital das Clínicas of the Federal University of Pernambuco in 2018. Data were collected from medical records and from the questionnaire, Research Diagnostic Criterion for Temporomandibular Disorders (RDC/TMD). The sample was composed of 81 parkinsonians and characterized using: sociodemographic variables and the presence or absence of muscular rigidity. The measures of vertical extension of the oral opening evaluated were: mouth opening without assistance and without pain (ABASD), and maximum mouth opening without assistance (AMBSA). The Pearson’s linear correlation and Spearman’s correlation tests were applied to investigate the relationship among the continuous variables. Analyses of association were conducted using simple logistic regression. The level of significance was set at p<0.05. Result Limitation of the oral opening was not related to age or sex. The greatest level of significance was between mouth opening without assistance and without pain and muscular rigidity (p=0.012), and years of schooling (p=0.038). Conclusion The limitation of mouth opening in people with PD was shown to be related to muscular rigidity and fewer years of schooling.

Abstract Introduction Autism is a complex neurological disorder with multifactorial causes, which compromises physical, psychological, emotional and social skills. This disorder also impairs dental care and patient oral health. Saliva can be easily obtained using a non-invasive technique and has been used in the diagnosis and screening of many pathologies. Total antioxidant capacity of saliva is reduced in the presence of caries in children and has been studied as a possible marker for autism. However, data on salivary antioxidants in children with autism spectrum disorder (ASD) is scarce. Objective This preliminary study evaluated the existence of gender influence on non-enzymatic antioxidant capacity and protein oxidative damage in the saliva of children with this disorder. Our hypothesis is that there are gender differences in these biochemical parameters in children with austim. Material and method Whole saliva samples were collected by aspiration between 8:00-11:00 am from 12 girls and 12 boys aged 5 to 15 years, with previous diagnosis for this disorder. Total antioxidant capacity, uric acid, protein concentration and oxidative damage to proteins were analyzed by spectrophotometry. Values were presented as mean ± standard deviation and tested for adherence to normality (Shapiro-Wilk test). The data were then compared using the Mann-Whitney test, considering a 5% significance level. Result There was no significant difference between groups for all analyzed parameters (P>0.05). Conclusion Based on the results obtained, we concluded that gender does not influence the levels of oxidative stress markers in the saliva of children with ASD.

Abstract Introduction Among the therapeutic effects of ozone therapy, improvement in cell metabolism and peripheral tissue oxygenation have been highlighted. Objective to evaluate the systemic effect of bio-oxidative therapy with ozone gas on wound healing. Material and method Tissue lesions with a circumference of 1.0 cm were induced in the skin on the back of 24 male Wistar rats. The animals were randomly divided into two groups: 1) Group C (control; n=12): with simulation of the application of ozone gas via the rectum and, 2) Group O3 (test; n=12): with application of ozone gas by means of rectal insufflation at a concentration of 50 µg/mL. The animals were euthanized at seven and 15 days, and samples were removed, fixed in formalin, and submitted to macroscopic, histological, and histometric analyses. Result The animals in the O3 group presented mixed inflammation at seven days, which translated into an absence of inflammation at 15 days. The C group exhibited acute inflammation on the 7th day, translating to chronic inflammation, which significantly increased from the 7th to the 15th day. The findings showed that the O3 group presented greater wound contraction (P<0.05) and a greater degree of neovascularization on the 7th day (P<0.05) when compared to group C. On the 15th day, both groups (O3 and C) showed complete re-epithelialization, however, the O3 group demonstrated complete muscle regeneration. Conclusion The systemic ozone therapy had a biomodulatory effect, reducing the characteristics of acute inflammation and increasing tissue repair and regeneration in rat skin.

Abstract Introduction Pulp and periodontal tissues may communicate and, in pathological situations, combined endodontic-periodontal lesions may be established. Objective The aim of this study was to evaluate the prevalence of endo-perio lesions in non-molar and molar teeth referred for endodontic treatment. Material and method The sample consisted of 104 teeth evaluated in 79 consecutive patients in a cross-sectional design. Visible plaque, probing depth, and bleeding on probing were evaluated. Endodontic evaluation included the presence or absence of caries, fistulas, pain, and pulp sensitivity. The presence/absence of periapical lesion, bone loss in the furcation region, and proximal area were evaluated. Result The results showed that pain was the main reason for seeking dental care in 63.3% of patients. The molar teeth demonstrated higher presence of probing depth (PD) ≥ 7 mm (38.3%) and higher PD mean (6.17 mm) than non-molar teeth (P<0.05). It was verified that 65.4% of the teeth were diagnosed with a primary endodontic lesion and that the periodontal component was present in 34.6% of the teeth, either in a primary (10.6%), secondary (11.5%), or combined form (12.5%). True combined endodontic-periodontal lesion occurred significantly in molar teeth compared to non-molar teeth (p<0.05). Conclusion The primary endodontic lesion was found in a greater proportion in teeth referred for endodontic treatment; however, approximately 1/3 of the sample had periodontal involvement, which demonstrates the importance of the periodontal examination together with the general clinical examination.

Conclusion The primary endodontic lesion was found in a greater proportion in teeth referred for endodontic treatment; however, approximately 1/3 of the sample had periodontal involvement, which demonstrates the importance of the periodontal examination together with the general clinical examination.","PeriodicalId":21363,"journal":{"name":"Revista de Odontologia da UNESP","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67175801","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abstract Introduction Fluoride is considered a key element in the remineralization process of tooth enamel. Objective To evaluate the influence of a topical solution of sodium fluoride (NaF) on the shear bond strength of orthodontic brackets and white spot lesions formation. Material and method Sixty bovine teeth were divided into three groups (n=20). Group 1 (Control): shear bond strength; Group 2: shear bond strength after pH cycling; Group 3: shear bond strength after pH cycling and treatment with 0.04% NaF solution. Groups 2 and 3 underwent pH cycling with demineralizing (6hs) and remineralizing (17hs) solutions at pH of 4.3 and 7.0 respectively for 15 days. The specimens were submitted to the shear bond strength and the Adhesive Remnant Index was verified (ARI). The specimens of each group (n=3) were qualitatively analyzed by means of Scanning Electron Microscopy (SEM). Kruskal-Wallis test assessed the shear bond strength and Fisher's exact test evaluated ARI, with significance level of 5%. Result There was no significant difference among the three groups in shear bond strength (p=0.2679). Significant difference was found in ARI (p=0.0199). The frequency of ARI 1 was 55% in group 1, 90% in group 2, and 80% in group 3. SEM showed difference between the enamel and bonding. Group 2 showed structural change of the enamel surface, adjacent to the bond area; and group 3 showed enamel with characteristics similar to those of group 1. Conclusion It was concluded that there was no NaF influence on the bracket shear bond strength and even in low concentrations it prevented the development of areas of demineralization of white spot lesions.

Abstract Introduction The association between smoking and periodontal diseases has been described in clinical and epidemiological studies. Objective The aim of this study was to compare the LL-37 and human β-defensin-2 (hBD-2) levels in crevicular fluid of patients with generalized periodontitis in smokers (S) and nonsmokers (NS). Material and method A total of 35 patients with generalized periodontitis stages III and IV, 15 NS (11 female, 4 male) and 20 S (7 female and 13 male), were included in the study. The evaluated clinical parameters were bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL). Enzyme-linked immunosorbent assays were performed to quantify the LL-37 and hBD-2 levels in the gingival crevicular fluid of these patients. The results were analyzed statistically with the level of significance set at 5%. Result In relation to periodontal clinical parameters, no statistically significant difference was observed for BOP and PD between groups S and NS. There was a higher CAL in the S group than in the NS group (p = 0.0095). There was no statistically significant difference between the levels of LL-37 and hBD-2 when comparing groups S and NS (p>0.05). Conclusion It was concluded that smokers have a higher clinical attachment loss than nonsmokers, but that smoking did not influence the levels of LL-37 and hBD-2 in the gingival crevicular fluid in periodontitis.
