Results: BF was significantly higher in normal teeth on the contralateral side compared to teeth restored with GIC and composite. However, in patients with amalgam restoration, though it was less compared to that on the contralateral side, it was not statistically significant (p>0.05). Conclusion: Restoring teeth with various filling materials may improve bite force. In the present study, it was found that the teeth restored with amalgam had higher bite forces in comparison to the other restorative materials used. However, it was not comparable to that observed in the normal tooth (control) on the contralateral side.","PeriodicalId":134552,"journal":{"name":"Brazilian Research in Pediatric Dentistry and Integrated Clinic","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135102359","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}

Material and Methods: 51 patients with either class I or class II division 1 sagittal relationship treated with the Damon system and the same archwire sequence were retrospectively selected. Dental casts of each patient before (T0) and after treatment (T1) were scanned and analyzed using NEMOCAST 3D software. Inter-molar, inter first-premolar, inter-second premolar and inter-canine distances were measured in both upper and lower arches. Initial and final lateral cephalograms were traced using the OrisCeph program. Pre and post-treatment measurements were compared using the t-test for repeated measurements. The Pearson Correlation Index and Linear Regression Analysis were used to determine the dependence between continuous variables. The significance level was set at 0.05. Results: Transversal diameters in the upper arch increase statistically significantly, especially in the bicuspid area. Initial intra-arch diameter was the only statistically significant variable correlated with the final expansion obtained. A linear negative correlation between the initial latero-posterior torque and the final expansion was observed in both arches. Conclusion: Using identical arches in patients with very different initial characteristics, the changes in bicuspids’ diameters remain the most predominant. Patients with initial more negative torque in the posterior region had a higher expansion amount.","PeriodicalId":134552,"journal":{"name":"Brazilian Research in Pediatric Dentistry and Integrated Clinic","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135059721","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}

The categories were geographic distribution, structural, human resources, work processes and access and coordination. Results: The total of 932 CEO’s were evaluated in 2014 and 1,042 in 2016, most of them type II, present in the Northeast region. In both cycles, the highest average of dentists worked in the endodontic specialty (2.4 professionals per CEO) and the lowest in oral medicine (0.8 professionals per CEO). Of the two cycles, 91.5% of the CEO’s had a manager, 79.5% performed action planning activities and 74.5% realized internal self-assessment processes. There was an increase in the mean number of days to be seen at the CEO in all analyzed specialties (p<0.001) and 85.2% of the CEO's managers reported that there is a reference for oral cancer confirmed cases. Conclusion: Between the PMAQCEO cycles the number of CEO has increased, but there are still a big pent-up demand and the presence of care gaps.

Test sites (left mandibular first molars) were treated with open flap debridement (OFD), DFDBA, and PRF, whereas control sites (right mandibular first molars) received OFD and DFDBA alone.

Results: The gain in relative horizontal clinical attachment level (RHCAL) in the test sites was 2.94±0.52 mm compared to 1.33±0.35 mm in control sites (p=0.01). Improvement in mean alveolar bone defect (MABD) (was 1.21±0.5 mm2 at test sites compared to 1.15±0.7 mm2 at control sites) probing pocket depth (PPD), recession, relative vertical attachment level (RVCAL), and percentage of bone fill was found in the test sites compared to control, which statistically insignificant.

The first appointment comprised chemomechanical preparation (2.5% sodium hypochlorite), smear layer removal (6% citric acid), intracanal dressing and temporary restoration. Seven days later, teeth were randomly assigned to filling with iodoform (IP) or calcium hydroxide with zinc oxide (CHZO) based pastes and temporarily restored.

Material and Methods: This systematic review was based on the search of laboratory studies in which selfetching adhesive systems were used. The electronic database PubMed was used for the search. The search began on August 2021 and ended on June 2022. We have analyzed the materials and methods of each research and entered them in the appropriate tables to give a clearer assessment of the obtained results. Results: This systematic review included 15 full-text articles published from 2011 to 2019. The ABRZ is formed on both dentine and enamel. On dentine, the ABRZ is formed only when using self-etching adhesive systems; on the enamel, on the contrary, the step of preliminary etch and rinse contributes to the formation of a thicker ABRZ. The functional monomer MDP and fluorine increase the thickness of the ABRZ and provide a hybrid layer /ABRZ boundary without defects and erosions. Conclusion: Self-etching adhesive systems ensure the creation of an ABRZ resistant to acid-base tests. This phenomenon can provide the resistance of tooth tissues to demineralization, and therefore increase their resistance to caries.","PeriodicalId":134552,"journal":{"name":"Brazilian Research in Pediatric Dentistry and Integrated Clinic","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135060055","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}

Material and Methods: Three stages were carried out: 1st, the 27-item of PFSQ was translated, back-translated, reviewed by a Committee of Experts and pre-tested (n=60), obtaining the cross-culturally adapted version. 2nd, the final version was self-applied by 42 mothers for internal consistency (Cronbach’s Alpha). After 2-weeks, 19 mothers answered the PFSQ again for reproducibility (Intraclass Correlation Coefficient, ICC). 3rd, 204 mothers of children aged 4-5 years answered the PFSQ for translation validation [convergent validity and exploratory factor analysis (EFA)]. Results: For subscales, Cronbach’s alpha ranged from 0.65 to 0.82; the overall reliability was 0.69, indicating substantial internal consistency. The ICC for overall PFSQ was 0.78 and for domains 0.56-0.89, indicating moderate to excellent reproducibility. ‘Control over eating’ correlated positively with ‘prompting/encouragement to eat’ and negatively with ‘instrumental feeding’; ‘prompting/encouragement to eat’ correlated positively with ‘emotional feeding’. By EFA, PFSQ items were loaded on four factors. ‘Control over eating’ and ‘prompting/encouragement to eat’ settled into two factors, whereas the ‘emotional’ and ‘instrumental feeding’ domains into one factor each.
