Material and Methods: Fifty four human teeth were collected for microleakage testing. Each assay comprised ICDAS 5 or ICDAS 6 carious lesions and sound teeth for controls. Sound teeth were prepared with cavities that mirrored the carious teeth cavities, which were prepared with SRCT-S. Sound and carious teeth were further randomly assigned to one of the three experimental groups: Group A: universal adhesive (UA) + CR, Group B: glass ionomer cement liner + UA + CR, and Group C: calcium hydroxide + UA+ CR. Occlusal microleakage (OM) and cervical microleakage (CM) was classified within one of 5 depth categories. ANOVA and Chi-square tests were computed (p<0.05). Results: OM and CM were similarly distributed across subgroups (p>0.05). All Group C samples with carious lesions presented some degree of microleakage. However, no statistically significant differences were observed between groups and within each group (p>0.05). Conclusion: Teeth restored with CR after SRCT-S using calcium hydroxide as a liner material seem to exhibit higher microleakage than those restored using glass ionomer or UA alone. Further clinical research is needed to deepen these findings. Clinical significance: The application of calcium hydroxide as a liner under a composite resin may reduce the longevity of a restoration after performing selective or partial removal of carious tissues. Clinicians should rethink the need of using calcium hydroxide for this application, albeit the lack of clinical evidence.","PeriodicalId":16625,"journal":{"name":"Journal of Oral Research","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83310811","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}

Objetive: To determine the association between the level of indifference to dental treatment and the oral hygiene habits of those surveyed adults. Material and Methods: An observational, analytical and cross-sectional study. The level of indifference to dental treatment was evaluated using a translated virtual questionnaire and subsequently internally validated (Cronbach's alpha: 0.91). There were a total of 249 participants, 150 males and 99 females, with a mean age of 30.69 years. For the association of the qualitative variables and the report of the crude and adjusted odds' ratio (OR), a logistic regression was used. We worked with a level of statistical significance of p<0.05 and a confidence interval of 95%. Results: A high level of indifference to dental treatment was obtained in 57.83% of the respondents. Likewise, a statistically significant association was found between indifference to dental treatment and education (p = 0.012). Regarding oral hygiene habits, a statistically significant association was found with flossing (OR = 2.22; 95% CI: 1.10-4.46) (p = 0.025) and brushing before sleeping (OR = 5.26; 95%: 2.26-12-22) (p<0.001). Conclusion: There is a statistically significant association between the level of indifference to dental treatment with oral hygiene habits, flossing and brushing before sleeping. It is advisable to carry out activities in the communities to promote oral health care to reduce levels of indifference to dental treatment.","PeriodicalId":16625,"journal":{"name":"Journal of Oral Research","volume":"103 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85719755","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 scientific literature is generally limited to opinions about the website, and it is likely that certain personal or academic characteristics of undergraduate students are related to its knowledge. Objective: To identify some socio-educational and scientific factors associated with knowing Sci-Hub in Peruvian dental students. Material and Methods: The study uses a cross-sectional secondary data analysis design. In regard to the main variable, we asked about knowledge of the existence of Sci-Hub and calculated association statistics. Results: There were 263 participants and the average age was 21.7. Of the total, 75% were female, and 59% knew about Sci-Hub. The multivariate analysis showed that knowing scientific journals (aPR: 2.35; 95% CI: 1.43-3.84; p=0.001), publication of scientific articles (aPR: 1.24; 95% CI: 1.00-1.54; p=0.046) and bibliographic search training (aPR: 1.45; 95% CI: 1.14-1.86; p=0.003) were factors associated with a greater level of knowledge in regard to Sci-Hub. In contrast, there was a lower level of knowledge among those with a basic level of English (aPR: 0.64; 95% CI: 0.50-0.82; p=0.001), adjusted for three variables.

Material and Methods: Cone beam computed tomography (CBCT) images of 26 subjects (12 men and 14 women) with anterior open bite were evaluated. The sample included 3 groups categorized by their sagittal skeletal relationship (based on ANB angle and anteroposterior dysplasia indicator (APDI)): Class I (n=9), Class II (n=6) and Class III (n=11). The total gonial angle, upper gonial angle, lower gonial angle, intergonial width, interantegonial width and antegonial notch depth were measured. ANOVA and Tukey tests were used for intergroup comparison. The Kruskal Wallis test was also used when necessary. In addition, the Pearson correlation coefficient was calculated to evaluate significant correlations between overbite and antegonial notch depth with gonial angle, Frankfurt mandibular plane angle (FMA) and the palatal plane-mandibular plane (PP-MP). Results: A significant difference was only found on the upper gonial angle between Class II and Class III (p=0.047). The upper gonial angle showed greater values (48°±3°) with the mandibular branch toward backward in Class III subjects and lower values (42.42°±4.39°) with the mandibular ramus leaning forward in subjects with Class II skeletal relationship. Besides, only a statistically significant correlation was found between overbite and the lower gonial angle (r=-0.418, p=0.034). Conclusion: Mandibular angle morphology is similar in anterior open bite subjects with different sagittal skeletal relationships, except for the upper gonial angle which is increased in Class III and decreased in Class II subjects with open bite. Lower gonial angle is negatively correlated with overbite. This difference should be considered by orthodontists when planning their treatments.","PeriodicalId":16625,"journal":{"name":"Journal of Oral Research","volume":"13 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73588682","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}

Through surface electromyography, the superficial muscles of mastication during right and left maximum bite force were evaluated. Results: No statistically significant differences in the maximum bite force were observed between the study groups. The data obtained from the electromyographic analysis of the superficial muscles of mastication demonstrate a trend indicating that subjects with a normal body mass index similarly activate the muscles on each side when performing a maximum bite force on a particular side, while overweight or obese subjects demonstrated significantly greater activation of the temporalis muscle associated with the side where the maximal bite force is performed.

Objective: To investigate and compare BD and MTA (mineral trioxide aggre-gate) in terms of proliferative, migratory, and adhesion effects on human pulpal and gingival cells. Material and Methods: Cells were incubated directly on the surface of BD and MTA disks. Adhesion (4 and 24 h) and proliferation (3, 5, 7, 14, 21) were evaluated with crystal violet and MTT assays (n=9 X each group). A wound-healing assay was performed for cell migration, with 0.2 and 2 µg/ml MTA or BD (n=6 X each group). The cut-off point for statistical significance was set at p<0.05, p<0.01 and p<0.001. Results: The best adhesion and proliferation results for gingival fibroblast (GFs) were obtained with BD (p<0.01). MTA and BD enhanced the migration of GFs in a dose-dependent manner, with superior results with BD, and 2 µg/ml was the optimal concentration for enhancing the migration of GFs. Conclusion: Results indicate that BD and MTA exhibit excellent compatibility in terms of cell adhesion, proliferation, and cellular migration. Also, the results suggested that BD is associated with better results than MTA in GFs. The results support the clinical application of BD in areas colonized with GFs.","PeriodicalId":16625,"journal":{"name":"Journal of Oral Research","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74132272","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}
