Prevalence of Dental Erosion in Children from Schools and Dental Clinics: A Cross-Sectional Study
No full textObjective: To investigate the prevalence of erosion in permanent teeth and associated factors. Material and Methods: A cross-sectional study was conducted with 208 children aged 8 to 11 years old, from public schools and dental clinics (both private and public). Data collection included a demographic and socioeconomic questionnaire, and questions related to dental erosion, as well as an oral clinical examination. Dental erosion (DE) in permanent teeth was assessed using the Tooth Wear Evaluation System (TWES). Chi-square test, and univariate and hierarchical multivariate Poisson regression were performed. Results: The overall prevalence of DE was 26%, being more prevalent in children from dental clinics (61.1%; p=0.003), those who consumed soft drinks (62%; p=0.016), and with attrition (51.9%; p=0.049). The sample of children from dental clinics, soft drink consumption, and the frequency of consuming acidic foods and beverages 2 to 3 times a day were suggestive factors for explaining DE (PRadjust=1.864; CI95% =1.072-3.242; PRadjust=2.027; CI95%=1.040-3.951; PRadjust=1.803; CI95%=1.171-2.775). The age of 11 years was revealed as a protective factor against DE (PRadjust=0.420; CI95%=0.196-0.899). Conclusion: Dental erosion was associated with dental clinic samples, consumption of soft drinks, and the frequency of consuming acidic foods and beverages
In Vitro Effect of Grape Seed Extract as an Intracanal Medication on the Mechanical Properties of Dentin
No full textObjective: To evaluate the mechanical properties of dentin under the effect of grape seed extract (GSE) as intracanal medication (ICM). Material and Methods: Ninety-six single-rooted bovine teeth were divided into groups, as follows: control group (Ctrl), without any dentin treatment; groups treated with Ca(OH)2 (Ca7, Ca15 and Ca30); and GSE (GSE7, GSE15 and GSE30), with direct contact between dentin and ICM for different durations of 7, 15 and 30 days. The samples underwent tests of maximum fracture load (FL), flexural strength (σf), cohesive strength (σc), and elastic modulus (E) of the remaining root. For statistical analysis, one-way ANOVA was used, followed by Dunnett\u27s test to verify whether ICMs interfere with dentin properties. Two-way ANOVA (ICM and application time) and Tukey\u27s test were also used, considering the groups treated with different ICM at different intervals. All analyses were performed at p ≤ 0.050. Results: GSE had a less pronounced effect on dentin\u27s mechanical properties compared to Ca(OH)2. GSE showed less interference with FL (p=0.000), σf (p=0.002), and σc (p=0.000). It was observed that the duration of exposure to ICM had a negative impact on FL (p=0.002) and σc (p=0.031). ICM (p=0.080) and the application time (p=0.985) did not significantly affect E. Moreover, the application time of ICM did not have a significant impact on σf (p=0.169). Conclusion:Grape seed extract did not affect the mechanical properties of bovine dentin when used as intracanal medication
Validity and Reliability of the Brazilian Version of the Children’s Experiences of Dental Anxiety Measure (CEDAM)
No full textObjective: To test the validity and reliability of the Brazilian Portuguese version of the Children\u27s Experiences of Dental Anxiety Measure (CEDAM). Material and Methods: The sample consisted of 80 pairs of parents and 9 to 12-year-old students at a public school in Ubá, Brazil. Children self-applied the CEDAM, Children\u27s Fear Survey Schedule-Dental Subscale (CFSS-DS), and Child Perceptions Questionnaire (CPQ8-10/CPQ11-14), and were clinically evaluated at school. Parents were interviewed about the child\u27s dental history, the Corah\u27s Dental Anxiety Scale, and the Parental-Caregiver Perceptions Questionnaire (P-CPQ). Criterion validity was assessed using the Mann-Whitney/Spearman\u27s correlation; construct discriminant validity was evaluated using the Mann-Whitney/Kruskal-Wallis test; construct convergent validity was examined using Spearman\u27s correlation; and predictive validity was assessed using multiple logistic regression. The reliability was calculated by Cronbach\u27s alpha and McDonald\u27s omega coefficients. Results: About 80% had already been to the dentist. Overall, highly fearful children had higher CEDAM mean scores than those who were less afraid, demonstrating criterion validity. In CPQ8-10 global ratings, those reporting "regular" oral health had the highest CEDAM scores compared to those reporting "very good", showing discriminant validity. For convergent validity, the CEDAM score was positively correlated with the CPQ8-10 emotional well-being domain. Moreover, significant positive correlations were observed between CEDAM scores and P-CPQ total scores and P-CPQ emotional well-being domain scores. The predictive validity was indicated by the greater chance that younger children with previous experience of dental visits, who had avoided and cried during dental treatment, presented higher CEDAM scores. Cronbach\u27s alpha of 0.93 indicated almost perfect internal consistency of the CEDAM. Conclusion: The Brazilian Portuguese version of CEDAM proved to be valid and reliable for application in 9 to 12-year-old children. Dental anxiety is more likely to be observed in younger children who have visited the dentist, avoided, and cried during dental treatment
Endodontic Treatments in Primary Teeth among Brazilian Dental Practitioners: A Preliminary Nationwide Cross-Sectional E-Survey
No full textObjective: To preliminarily evaluate the endodontic treatments in primary teeth carried out by Brazilian dental practitioners. Materials and Methods: A preliminary nationwide cross-sectional e-survey was conducted. The data collection took place from December 2023 to January 2024. The sample consisted of 77 dental practitioners, based on their initial responses to a 32-item self-administered questionnaire that addressed the features of treatments provided in Portuguese. The instrument was made available online, and its link was distributed via messaging apps and social media campaigns. The significance level was set at 5% (α = 0.05), and Pearson\u27s chi-squared test was used to assess associations. Results:Among the respondents, 61% carry out indirect pulp capping, 53.2% carry out direct pulp capping, 40.3% carry out pulpotomy, and 31.2% carry out pulpectomy in primary teeth. Respondents aged up to 35, working in public dental services, and self-assessing their knowledge as \u27very good\u27 or \u27good\u27 were more likely to provide some endodontic treatment in primary teeth (all p <0.05). Furthermore, 41.6% of the respondents did not rate their knowledge about endodontic treatments in primary teeth as \u27very good\u27 or \u27good\u27, and 49% of the providers reported referring children in need of endodontic treatments \u27frequently\u27 or \u27occasionally\u27. Calcium hydroxide was the most commonly used material for direct or indirect pulp capping (78.7% and 68.1%, respectively) and pulpectomies (54.2%). In pulpotomies, Mineral Trioxide Aggregate (MTA) was the most frequently used material (45.2%), with its usage similar to that of calcium hydroxide (38.7%). Conclusion: There was notable variability in the characteristics of endodontic treatment providers for primary teeth among Brazilian dental practitioners

Prevalence of Self-Reported Halitosis and Associated Factors: A Cross-Sectional Study among Dental Patients
Get PDFObjective: To determine the prevalence of self-reported halitosis among patients attending the dental clinic of a university in southern Brazil and identify associated factors. Material and Methods: The sample of this cross-sectional study included 269 individuals over 18 who attended the clinic for six months. A questionnaire was used to collect data on self-reported halitosis, sociodemographic characteristics, oral hygiene habits, medication use, systemic diseases, smoking and drinking habits, and self-perception of oral health. The relative and absolute frequencies of the variables were analyzed, and multivariate binary logistic regression analysis was performed to obtain odds ratios (OR) and respective 95% confidence intervals (95%CI) at p < 0.05. Results: The mean age of the sample was 44.86 (±16.55), and 65% were female. The study found a self-reported prevalence of halitosis of 27.9%. Individuals who reported xerostomia were more likely to have self-reported halitosis (OR=2.15; 95% CI: 1.22-3.78). Furthermore, those who visited the dentist more than a year ago were more likely to have self-reported halitosis compared to those who visited no more than six months ago (OR=1.93; 95% CI: 1.09-3.41). Conclusion: The study showed a high prevalence of self-reported halitosis among patients and revealed an association with individuals who reported having xerostomia and who have been attending dental appointments for a longer time
Awareness and Practice of Deep Margin Elevation among Dental Practitioners in India: A Cross-Sectional Survey
Get PDFObjective: To evaluate knowledge, attitude and practice of deep margin elevation (DME) amongst dental practitioners in India, thereby increasing awareness. Material and Methods: A cross-sectional study was carried out among academicians, private practitioners, and post-graduate students, comprising 266 participants. Twenty-three close-ended web-based questionnaires were circulated through Google Forms. Data was analyzed using the Chi-square test, and descriptive analysis was performed using the Statistical Package for the Social Sciences software. Results: Although most respondents were aware of DME, only 27.4% claimed to have used this approach in daily practice. 60.4% reasoned out that DME was a technique-sensitive procedure. However, 50% of participants prefer to use DME as a substitute for surgical crown lengthening. There was a significant association between awareness regarding the term DME, knowledge of the procedure, and the study participants\u27 cadre (p=0.024 and p=0.214, respectively). Conclusion: Knowledge, attitude, and practice of DME among dental practitioners in India are adequate. However, few dentists use this method to treat extensive subgingival decay in clinical practice. This can be attributed to the lack of literature on the subject and the perceived difficulties of the procedure. There is a need for more clinical research to understand the long-term prognosis of teeth restored using this technique and to encourage its usage in practice
Evaluation of Factors Determining the Causes of Removable Partial Dentures Replacement
Get PDFObjective: To evaluate the correlation of different problems that lead to the replacement of removable partial dentures (RPD). Material and Methods: The sample included 231 patients with an RPD [female (n=120) and male (n=111)], age range (22-74) years. We take general information including name, age, gender, level of education and chief complain. The chi-square test was used for the analysis of data where appropriate. P-values were considered statistically significant if they were less than 0.05. Results: The largest number of the female complain from pain and discomfort (n=35) while for male complain from lose or fracture of the denture (n=40). Regarding age, the largest number of patients complained of lose or fracture of the denture (n=51) for the age group range 40-57 years, while for the age group range (22-39) years complained of esthetic problems (n=27), and for group age range 58-75 years the most significant number complain from pain and discomfort (n=24). About education level, the highest percent was for not educated patient by (61%). The highest percentage was for lose or fracture of the denture (31.6%), and the lowest percentage was for functional problems (11.7%). There was a statistically significant association between the chief of complaint and the level of education (p=0.007). Conclusion: There is no correlation between gender and the decision to replace removable partial dentures. The age affects the patient\u27s decision to replace removable partial dentures. However, the level of education has a significant effect on the replacement of removable partial dentures
Screen Time and Musculoskeletal Pain in Dental Students
Get PDFObjective: To investigate the association between screen time and musculoskeletal pain in dentistry students at a Brazilian public university. Material and Methods: A cross-sectional study was conducted among dental students enrolled in the undergraduate program. Data collection was carried out through the application of a sociodemographic questionnaire and the Pain and Electronic Media Questionnaire involving a population group of 229 students with specific characteristics, using a convenience sampling method. Due to the pandemic, data was collected from January to December 2022 using Google Forms. Results: Most researched participants were from the 7th to the 10th period. It was possible to verify that 95.6% stated that their cell phone is the most used equipment. Furthermore, 71.6% reported using their cell phone five or more hours daily. The students also mentioned that 61.6% experienced back pain, 56.3% experienced neck pain when using a computer, 31% reported back pain, and 20.1% reported neck pain when playing electronic games. Regarding cell phone use, the locations where pain was most frequently reported were the wrists and hands (49.8%). Conclusion: The study highlights the impact of prolonged screen time on musculoskeletal pain among dental students, emphasizing the need for ergonomic interventions and educational programs to address and prevent discomfort associated with extensive use of digital devices
Selenomonas spp. and Periodontal Diseases: A Systematic Review
Get PDFObjective: To assess the association of Selenomonas species with periodontitis through a systematic review. Materials and Methods: A search was conducted to identify articles published between January 1, 2000, and September 2, 2024, in English and French, in the electronic databases PubMed, Scopus, and Web of Science. The inclusion criteria were human studies, including patients with periodontitis aged 18 years or older, and non-interventional cross-sectional, case-control, and cohort studies. Exclusion criteria were smoking, chronic systemic diseases, and pregnancy. The risk of bias was evaluated using the Newcastle-Ottawa Scale (NOS). Results: Among the 6226 identified studies, only six met the inclusion criteria and were appropriate for answering the research question. They found a higher prevalence of Selenomonas species in patients with periodontitis than in healthy subjects. Additionally, two species, S. sputigena, and S. noxia, were frequently isolated from subgingival plaque and were associated with periodontal status. Conclusion: S. sputigena and S. noxia have been associated with periodontitis, including both aggressive and chronic forms, and may be considered putative pathogens in the disease. However, no robust evidence can be set since heterogeneous protocols were used in the included studies. Therefore, more research is necessary to refine this association
