Methods: After approval by the CCS/UFES Ethics Committee (registration number 2,738,749), consultations were undertaken, and data were collected from medical records in cooperation with sectors from UFES and the University hospital. A total of 50 patients, 29 with osteoporosis and 21 with osteopenia were selected. Patients underwent a clinical and a panoramic dental x-ray examination to assess risk factors associated with oral health and dental interventions. Results: All patients had at least one local risk factor, the most frequent being tooth extraction (100%) and periodontal disease (50%) which, if associated with the use of BFs, could lead to MRONJ. Among the systemic risk factors, the most common were diabetes and corticosteroid therapy. The most used BF was alendronate, administered orally. Conclusion: The dental surgeon should evaluate all patients with osteopenia and osteoporosis using BFs to determine whether there are other risks. Whether there may be other potential risks, acknowledging upon key risks factors surrounding MRONJ are critical for early diagnosis and successful dental treatment.","PeriodicalId":504767,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141823237","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}

Aim: To evaluate and compare undergraduate medical students’ knowledge, attitude, and practice about early childhood oral health care before and after educational intervention. Methods: A cohort study was conducted among undergraduate medical students during their course. The baseline knowledge and attitude of 80 medical students were evaluated using a validated questionnaire (Phase I). Following, they completed 8 hours of educational intervention and their change in the knowledge and attitude was reassessed (Phase II). The intervention continued through web-based learning till they reached their residency. The students’ knowledge, attitude, and practice were again reassessed at the end of their residency (Phase III). Results: Knowledge: There was a significant increase in the knowledge about the term gum pads, from 70% in Phase I to 90% in Phase III. Only 30% of medical students knew that the oral cavity of a newborn was devoid of microorganisms during Phase I, but this knowledge improved to 86% in Phase III. Almost 58 to 90% of the medical students had a basic knowledge of the influence of high caries on mothers, the importance and benefit of antenatal counselling, and the effect of poor maternal health. In Phase I, although 92% were aware of the multifactorial pattern of dental caries, only 42% and 53% knew the causative organism and transmissibility of it from mother to child, respectively. Around 77% and 62% agreed that antenatal counselling and counselling on feeding and weaning, respectively, will prevent ECC. Attitude: The attitude towards treating primary teeth was less (66%) in Phase I, subsequently increasing to 100% at the end of Phase III. Practice: Following Phase III, most of them (88%) examined the child’s oral cavity during routine medical checkups in the Knee-to-Knee position (93%) and counted the number of teeth present (91%), and they were able to identify the dental carious teeth (88%).

Methods: A total of 12 rats were allocated in two groups according the experimental model used to evaluate the bone repair in grafted areas: a critical sized-calvaria defect of 5 mm filled with bone graft (n=6) and a mandibular ramus filled with the bone graft associated with a Teflon dome-shaped membrane (n=6). Both groups were grafted with deproteinized bovine bone graft. After 60 days, the animals were euthanized and the samples obtained were submitted to histomorphometry analysis to evaluate the relative amount of bone, remaining bone substitute, and soft tissue within the grafted areas. Results: No differences were observed between the preclinical models evaluated in relation to the amount of bone tissue formation (19.93 ± 4.55% in calvaria vs. 21.00 ± 8.20% in mandible). However, there was a smaller amount of soft tissue (43.20 ± 10.97% vs. 57.79 ± 7.61 %; p<0.01) and a greater amount of bone substitute remaining (35.80 ± 5.52% vs. 22.28 ± 4.36 %; p<0.05) in the grafted areas in the mandible compared to calvaria defect.

Methods: The root canals of 60 single-rooted extracted human teeth were perforated artificially at a point 10 mm away from the root apex. After measuring the actual lengths up to the perforation point, the teeth were then put within an alginate mould for measurements using an integrated apex locator. Using a #20 K-file in the presence of NaCl, CHX, MTAD, NaOCl, and QMix, an electronic apex locator was used to measure the perforations electronically in accordance with the manufacturer’s instructions. Between the measurements, each canal was dried with paper points after being irrigated with distilled water. The accuracy of all the readings was calculated at ± 0.5 mm. Statistical analyses were performed using the Z-test. Results: In comparison to the MTAD, NaOCl, and Qmix, saline and chlorhexidine scored more readings in the ± 0.5 mm range of the perforation site, and the difference was statistically significant.

This was assessed through evaluations of the modulus of elasticity and changes in mass. Methods: Seventy dentin collagen matrices (demineralized sticks) were prepared to receive treatments with ethanolic solutions of CAPE at concentrations of 0.05%, 0.1%, 0.5%, or 2.5%, or with control treatment solutions (distilled water or ethanol) for one hour. The dentin matrices were evaluated for modulus of elasticity and mass before (baseline), immediately after treatment (immediately), and after storage in Simulated Body Fluid (SBF) for time intervals of 1 and 3 months. Results: Generalized linear models for repeated measures over time indicated no significant differences between groups (p=0.7530) or between different time points (p=0.4780) in terms of the modulus of elasticity. Regarding mass variation, no differences were observed in the time interval between 1 month and the immediate time (p=0.0935). However, at the 3-month mark compared to the immediate time, the 0.1% CAPE group exhibited less mass loss compared to the water group (p=0.0134). Conclusion: This study concludes that various concentrations of CAPE in an ethanolic solution did not affect the modulus of elasticity of dentin, suggesting that CAPE lacks biomodifying potential in this context. However, it was observed that 0.1% CAPE positively influenced the variation in mass over different evaluation time intervals.","PeriodicalId":504767,"journal":{"name":"Brazilian Journal of Oral Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2024-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141010768","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}
