Methods: the present split-mouth study was composed of 406 individuals with complete unilateral cleft lip and palate who had completed the rehabilitation process in a single tertiary cleft center (55.9% males). The information was collected from the dental history on the patients’ records and radiographs. The frequency of endodontic treatment in the upper incisors and canines was calculated for the cleft and non-cleft sides. The comparison between sides was performed by the chi-square test (p <0.05). Results: endodontic treatment was more frequent in teeth adjacent to the cleft than in contralateral teeth. The frequency of endodontic treatment in at least one tooth adjacent to the cleft was 18.97%, and 11.6% on the contralateral side. It was observed that endodontic treatment was necessary in 63.5% of patients who had been submitted to orthodontic treatment, 42.4% of those rehabilitated with fixed partial dentures and 12.0% of patients who underwent dental reshaping of teeth adjacent to the cleft. The treatments performed included vital pulp therapy (46.1%), non-vital pulp therapy (46.8%) and endodontic retreatment (7.1%). Conclusion: in individuals with complete cleft lip and palate, teeth close to the bone defect area and used for rehabilitation treatment presented greater need of endodontic intervention.","PeriodicalId":34984,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135471533","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}

Methods: Teeth were distributed into groups (n=5), according to the resin cement (Maxcem Elite-(MC) or NX3 Nexus-(NX)) and degradation method (24h or 7 days in distilled water; 7 or 30 days incubated with biofilm and 30 days in sterile media). Treated surfaces of Vita Enamic blocks (5x6x7mm) were luted to treated or no treated dentin surfaces and light-cured. After 24h, beams were obtained (1x1x10mm) and stored accordingly. The flexural bond strength (FBS) was assessed by four-point bending test. Additional beams were obtained from new teeth (n=5), stored for 24h or 7 days in distilled water, and submitted to a microtensile bond strength (μTBS) assay. Failure modes were determined by scanning electron microscopy (100X). The flexure strength of the cements (n=10) was assessed by a four-point bending test. Data were analyzed by 1 and 2-ways ANOVA, and Tukey’s test (α=0.05). Results: There was no significant difference between the degradation methods for the FBS groups. For the μTBS, the significant difference was as follows: NX 7days > NX 24h > MC 7days = MC 24h. Failure mode was mainly adhesive and mixed, but with an increase of cohesive within cement and pre-failures for the MC groups assessed by μTBS. NX had better performance than MC, regardless of the method. Conclusions: The biofilm had no effect on the materials BS and FBS test was a useful method to evaluate BS of materials with poor performance.","PeriodicalId":34984,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135471236","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}

Methods: 60 specimens (n = 10) of Bulk-Fill composite resins were made: M1 – Filtek™; M2 – Tetric N-Ceram and M3 – OPUS, through a matrix 2x6 mm and light cured by the VALO light source. After polishing, initial analyzes (48 hours - T0) of surface roughness (Ra), microhardness (VHN) and color change (ΔE) were performed. To simulate the oral condition of severe gastroesophageal reflux and bulimia, the specimens were immersed in hydrochloric acid (S1) (pH 1.7) 4 minutes a day, for 7 days. Control group specimens were immersed in artificial saliva (S2). Subsequently to immersions, mechanical brushing was performed for 3 minutes, three times a day, simulating 7 days of brushing. And again, the analyzes of Ra, VHN and ΔE were performed (7 days - T1). Thus, hydrochloric acid immersion, mechanical brushing and Ra analysis were repeated at 14 days (T2) and 21 days (T3); and T2, T3 and T4 (3 years) for VHN and ΔE. Results: After Shapiro-Wilk statistical test, ANOVA and Tukey test with Bonferroni adjustment (p>0.05), M3 showed the lowest Ra at all times compared to the other resins, while the highest Ra was at T0. M1 and T1 showed higher VHN. And M2 and T4 showed higher ΔE.

Methods: This was a cross-sectional study covering OHCWs from a single multicenter research centre. A self-administered and validated online questionnaire was used for data collection, including the following variables: sociodemographic, medical history, biosafety, professional experience, surveillance, and education. Results: The sample consisted of 644 OHCWs (82.5% dentists, 13.2% dental assistants and 4.3% technicians), most without comorbidities (84.8%), from the public (51.7%) and private (48.3%) health systems, in 140 cities of a southern state. The most prominent measures of surveillance were waiting room distancing and visual alerts, symptom assessment, and availability of guidelines on COVID-19. Regarding biosafety measures, the lowest adherence was related to intraoral radiographs (2.7±1.4; 95%CI: 2.6–2.9), use of dental dams (2.1±1.4; 95%CI: 2.0–2.2), and availability of high-power suction systems (2.5±1.7; 95%CI: 2.3–2.6). Among OHCWs, 52.6% received guidance on measures to take during dental care in the workplace. Continuing education was mainly through documents from non-governmental health authorities (77.4%). Conclusion: Surveillance and biosafety measures were adopted, but activities that reduce the spread of aerosols had less adherence. These findings underscore the importance of considering dental practices, and surveillance and education strategies to formulate policies and relevant support to address health system challenges during the COVID-19 pandemic. A coordinated action of permanent education by policymakers is necessary.","PeriodicalId":34984,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":"63 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77774071","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}

Immediate anatomical zirconia implants were introduced to match the shape of the extracted root and fill the socket without gaps while still providing better metal-free appearance. Aim: This study aims to investigate success and survival rates of immediate anatomical zirconia implants. Methods: This prospective interventional study was held between 2017 and 2020 in the faculty of dental medicine, Damascus University, Syria. The sample consisted of 27 immediate anatomical zirconia implants in 21 patients from both genders. Implants were designed and manufactured starting from CBCT image and prior to extraction. Specialized software applications were used to modify implant design. Implants went through different processing procedures to make them ready for insertion immediately after tooth extraction. Restorations were made after a minimum period of 3 months, clinical and radiographic follow ups were performed after 10 - 13.5 months from restoring the implants in order to evaluate their success/ survival. Repeated measures ANOVA was used to assess marginal bone loss, t test for probing depth assessment. Results: Immediate anatomical zirconia implants showed success in (n=17) 63% of total cases, satisfactory survival (n=3) 11.1%, compromised survival (n=2) 7.4% and they failed in (n=5) 18.5%.

Most students (81.44%) felt secure performing clinical care during the COVID-19 pandemic. Students undergoing specific biosafety training for longer than one hour felt safer than those perfoming training for up to 1 hour (p=0.004). Students from schools where the aerosol-producing restriction was applied felt safer than those without restrictions (p=0.016). Women reported feeling less secure than men (p=0.046), and students who submitted to COVID-19 Specific Biosafety Training felt safer in clinical activities than those submitted to theoretical training only (p=0.011). Students from private universities presenting psychosomatic changes felt less secure in practicing clinical dental care activities (p=0.006). In conclusion, time-spent training in biosafety, restriction of the use of aerosol-producing procedures, and the gender of students were associated with the self-perception safety of students.

Methods: Two government Iraqi dental schools [(the University of Baghdad (UOB) (n=99) and University of Babylon (UB) (n=70)], and one private dental school [Osouldeen University College (OUC) (n=103)] were included in this survey study. A paper-based questionnaire composed of seven questions was distributed to students, and collected. A chi-square test was used for data analysis, and the level of significance was set at 0.05 (P=0.05). Results: A statistically significant difference (P<0.05) was identified between students’ answers in the three dental schools regarding antibiotic selection for endodontic infections in which patients had no known allergies (P=0.001). In comparison to other dental schools, a statistically significantly higher proportion of respondents from UOB (32%) favored Azithromycin 500mg for treating patients with penicillin hypersensitivity (P=0.003). A high percentage of participants (62.1%) selected antibiotic prescription in cases with necrotic pulp and symptomatic apical periodontitis (with swelling and moderate/severe preoperative symptoms). However, there were no significant differences between the 3 dental schools (P>0.05). Conclusion: In conclusion, a significantly greater percentage of UB chose amoxicillin for the treatment of endodontic infection in patients with no medical allergies. Azithromycin 500mg was selected by UOB as the preferred option in patients who were sensitive to penicillin. Our findings support the need for the implementation of strategies to raise awareness of good antibiotic prescribing practices among dentists in Iraq.","PeriodicalId":34984,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84424018","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}
