Use of Sealants in Permanent Molars by Brazilian Dentist: A Comparative Study of Public versus Private
Get PDFObjective: To compare the use of sealants in permanent molars between public and private dentists in Brazil. Material and Methods: This was a cross-sectional and analytical web survey study. The convenience sample consisted of dentists in Brazil who answered a pre-tested online form released via social media between July and October 2021. Descriptive analysis was performed using absolute and relative frequencies (%) and associations using the Chi-square test (p<0.05). Results: Brazilian professionals participated in the study (n=2,244). Comparing the professionals from the public service with those from the private service, the former had a higher positive perception of the use of sealants as a preventive (92.4% vs. 81.1%, p<0.001) and therapeutic procedure (90.7% vs. 82.4%, p=0.001), higher percentage of non-invasive (91.7% vs. 83.8%, p<0.001) and invasive (22.8% vs. 12.0%, p< 0.001) techniques. Professionals from the private service reported more frequently that they did not use sealants than those from the public service (14.0% vs. 4.8%, p<0.001). Resin sealant (97.7% vs. 94.9%, p=0.015) and Flow resin (62.0% vs. 54.3%, p=0.013) were the most used by professionals in the private service. The use of glass ionomer cement was not associated with the type of service (75.1% vs. 77.2%, p=0.172), nor was the use of adhesives (0.6% vs. 1.4%, p=0.195) or resin with Giomer technology (1.9% vs. 2.2%, p=0.856) (p>0.05). Conclusion: The percentage of use of sealants among dentists in Brazil is high, especially among professionals in the public service, and the most used materials were resinous sealants and glass ionomer cement

Results: The samples comprised terpenes and terpenoids: monoterpenoids, sesquiterpenoids, diterpenoids, hydronaphthalene, succinic acid, and isopimaric acid. These have therapeutic potential for several diseases, inhibit several stages of the inflammatory process, and improve the symptoms caused by it. Conclusion: The amber of this sample tested is formed by terpenes and terpenoids, substances with anti-inflammatory and analgesic. However, an in-depth study is needed on the release and absorption of substances in human skin or their actual effectiveness
A Comparative Analysis of Three Online Drug-Drug Interaction Checkers: A Short Communication
Get PDFObjective: To assess the agreement among three different online drug-drug interaction (DDI) checkers for the detection of psychotropic drug interactions among dental patients in the state of Minas Gerais, Brazil. Material and Methods: Between January and December 2017, a cross-sectional study was conducted in Minas Gerais with data on pharmaceutical claims of psychotropic drugs prescribed by dental practitioners. Data from the Pharmaceutical Management System provided the drug dispensing history of the patients, allowing the identification of those on concomitant medication use. The occurrence of DDI was determined by entering the name of the drugs taken by each patient into Merative Micromedex®, Medscape®, and DrugBank. The degree of agreement among the three DDI online checkers was analyzed using the Fleiss\u27 kappa test. Results: Overall, 797 dental patients were found to be taking some psychotropic medication with other drugs simultaneously. The number of patients with DDI varied according to Micromedex® (n= 366), Medscape® (n= 473), and DrugBank (n= 736). The agreement between the DDI checkers was poor (Fleiss\u27 kappa: 0.165; p<0.001). Conclusion: The online DDI checkers assessed in this study showed variations in their ability to detect interactions and poor agreement among them
Model Proposal for Equity Production in Access to Dental Specialty Centers
Get PDFObjective: To address disparities in oral healthcare to allow prioritization of individuals with higher vulnerability. The model seeks to develop a methodology for identifying and classifying vulnerability among CEO users using socioeconomic indicators. Additionally, it aims to establish criteria for access prioritization based on vulnerability profiles, ultimately ensuring that those in greater need receive the specialized oral healthcare they require. Material and Methods: The proposed method leverages two key indicators: the Municipal Social Vulnerability Index (IVS) and the CEO Social Vulnerability Indicator (CEO IVS). CEO IVS is calculated based on CEO user socioeconomic data and compared to the municipality\u27s IVS. The model utilizes a scoring system to classify users\u27 vulnerability levels, allowing for the identification of those most in need of specialized care. The Equality Production Trend Indicator (ITPE-CEO) assesses the alignment between CEO and municipal vulnerability levels, aiding access prioritization. Conclusion: This equity-focused model offers a practical approach to address disparities in oral healthcare access. Vulnerability profiles and socioeconomic factors empower local managers to allocate resources effectively, ensuring that individuals with higher vulnerability receive timely and specialized care. The proposed model promotes inclusivity and responsiveness to community needs, contributing to achieving equitable oral healthcare for all
The Effect of Restoration Polymerization and Residual Dentine Thickness on Thermal Changes of Pulp Chamber of Immature Permanent Teeth
Get PDFObjective: To evaluate the pulpal temperature changes due to the polymerisation of resin and glass ionomer-based materials in dentine thicknesses in immature permanent teeth with open apices. Material and Methods: Forty extracted sound human third molar teeth with open apices were included. The width of the cavities prepared on the occlusal surface was 4×5 mm. The depth was 2 mm in the resin groups. 4 mm in the groups in which glass ionomer liner was applied before composite restoration. The coronal parts of the samples were then placed on an acrylic plate with three gaps for feeding-extraction needles and the thermocouple. The temperature changes were recorded. The data was analyzed by SPSS. Statistical significance was accepted as p<0.05. Results: The temperature increase in the group of 1 mm remaining dentin thickness revealed higher results than the values detected from the 2 mm group (1.01 °C) (p=0.00). The mean values (1.49 °C, 1mm) of temperature changes in only glass ionomer applied group were lower than the avarage values (2.210°C, 1mm) determined in the polymerization process of resin composites with light-emitting diode devices. Conclusion: In a remaining dentin thickness of 1 mm in teeth with open apices, using a glass ionomer liner might be a useful effort for protecting the pulp from the heat generated by polymerisation devices
Development of a Questionnaire to Describe Endodontic Treatments in Primary Teeth among Brazilian Dental Practitioners: Face and Content Validity
Get PDFObjective: To develop a questionnaire to describe endodontic treatments in primary teeth among Brazilian dental practitioners, focused on face and content validity (FCV). Material and Methods: An online validation process involved ten judges (panel of experts) and 32 dental practitioners (pre-test). The initial questionnaire (33 items) was developed after a literature review and divided into two parts: 7 questions for characterizing Brazilian dental practitioners (Part 1) and 26 questions for characterizing the endodontic treatment in primary teeth carried out by them (Part 2). The questionnaire was assessed for appearance, comprehension, and relevance using a 4-point Likert scale. Validity was achieved when the Validity Index was equal to or greater than 80% (0.8), considering responses 3 or 4 acceptable. Results: Two rounds were necessary for all items of the data collection instrument to be validated. The Validity Index for the entire instrument was established at 0.97 among the experts and 0.95 among the pre-test participants. The appearance, comprehension, and relevance criteria within the panel of experts achieved Validity Indices of 0.94, 0.97, and 0.99, respectively. The pre-test participants\u27 values were 0.97, 0.94, and 0.94, respectively. The approximate response time for the data collection instrument ranged between 5-6 minutes. Within the expert panel, 70% of the judges rated the difficulty of filling it out as "easy." Among the pre-test participants, 56.3% judged it "very easy." Conclusion: After this validation process, the questionnaire has acceptable face and content validity and is uncomplicated and quick to fill out
