Materials and Methods: This cross-sectional study used the shortened version of the “Dundee Ready Educational Environment Measure” (DREEM-17) and was administered to 200 students of a dental school in south India using a convenient sampling. DREEM-17 consists of 17 questions under five domains recorded on a Likert scale. Higher scores implied a better perception of the educational environment. Based on the results of university examinations, students were grouped as academic achievers and under-achievers. Independent sample t-test and analysis of variance with post-hoc test were used to evaluate significant differences with gender, academic year, and academic achievement. The relationship between academic achievement and the DREEM scores was evaluated with Poisson regression after adjusting for the academic year. Results: The final analysis included 183 students (91.5% response rate). The majority of the participants were females (92.3%) with a mean age of 20.84 ± 1.41 years. Only 16.9% were under-achievers. There was a significant difference in the total mean scores concerning the academic years (P < 0.001). Under-achievers, as compared to academic achievers, scored lower mean total DREEM (P = 0.005). Regression analysis showed that academic achievers perceived significantly higher DREEM scores after adjusting for the academic year (risk ratio = 0.96; 95% confidence interval = 0.95–0.98; P < 0.001). Conclusion: Academic achievers fared higher DREEM scores than under-achievers. The use of DREEM-17 as a tool for monitoring academic progress might facilitate the identification and implementation of timely interventions to modify any problematic educational situations.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"518 - 523"},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45804237","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 aim of this scoping review is to summarize the available evidence on the relationship between preterm birth and the development of early childhood caries (ECC). Materials and Methods: A systematic search was performed in PubMed, Cochrane Database of Systematic Reviews, Lilacs, and Epistemonikos up to January 6, 2022. Two authors screened studies by title and abstract and by full text to select those that fulfilled the eligibility criteria (observational/randomized clinical trials/systematic reviews that assess dental caries in primary dentition and premature delivery in children between 1 and 6 years old with cavities in deciduous teeth and published in Spanish, English, and Portuguese. Studies combining deciduous and permanent teeth, and with patients that had dental trauma were excluded). Any disagreement between the two reviewers during the selection process was solved by discussion, and a third reviewer got involved in case of disagreement. Two reviewers independently extracted data from the included studies. Results: We identified 1480 studies from the initial search resulting in 17 studies included in this scoping review. Six studies were cross-sectional, three were cohort studies, five were case–control, two studies were systematic reviews, and one was a meta-analysis. In terms of the association between dental caries and prematurity, conclusions of the included studies are controversial. Nine studies concluded that there is no relationship; six studies demonstrated that there is a relationship, and two studies did not specify whether there is a relationship between dental caries and prematurity. Conclusion: We found that there is no conclusive evidence to demonstrate if there is a relationship between ECC and prematurity because of the high ambiguity of the evidence. It is necessary to carry out more prospective cohort studies with a larger sample size and a defined premature population who are followed up for a longer period when they have a complete deciduous dentition.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"454 - 461"},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44547424","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}

Basic fibroblast growth factors and vascular endothelial growth factors are found in hDPSCs, and they can help speed up the vascularity and bone development. Oxysterol is an oxidized cholesterol product that can be found naturally in humans and animals. Oxysterol is an osteogenic factor that affects osteogenic differentiation by activating the liver X receptors and the Hh pathway signaling. Hyaluronic acid is a nonsulfate linear polysaccharide made up of disaccharide units of D-glucuronic acid and N-acetyl-d-glucosamine that occur naturally, which are linked by β-glycosidic bonds 1–3 and β-1–4. The hyaluronic acid scaffolds can be used for bone regeneration by increasing osteogenesis, osseointegration, and mineralization. The study aimed to describe the potential for combining hDPSCs and oxysterol in media hyaluronic acid scaffolds for dental implant therapy. Materials and Methods: Ideas and innovations were obtained based on the literature in journals and textbooks in the last 5 years (2016–2021) from PubMed, Google Scholar, and Web of Science databases. The review used the technique to find the similarity of the literature with the same keywords and then made conclusions. The theories that have been obtained are then summarized into a continuous series; thus, readers can more easily understand the ideas and innovations offered. Results: Pertaining to various literatures, there were 30 journals from PubMed, Google Scholar, and Web of Science databases. The case reports analyzed patients with inclusion criteria for dental implants and osseointegration. From the results of the review, it was found that the combination of these three ingredients has ingredients that can induce osseointegration. Conclusion: The combination of hDPSCs and oxysterol in media hyaluronic acid scaffolds can potentially provide bone regeneration in dental implant treatment.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"440 - 446"},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49012402","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}

Materials and Methods: Orthodontic adhesive material was removed from the buccal surface of 40 maxillary premolars after bracket debonding with four techniques as 10 teeth per each one: TCG = 10; TCPG = 10; EFG = 10; and EFPG = 10. The operating time required for the completion of each technique was recorded in seconds using a stopwatch, and the mean values of it were statistically calculated; ANOVA and least significant difference tests for means and significant difference of it were done. The enamel surface of two samples from each group in addition to the control group was evaluated by using scanning electron microscopy (SEM), and Enamel Damage Index (EDI) was used for assessing enamel surface damage by using ImageJ software. Results: Depending on the SEM evaluation and EDI, the results are as follows: EFPG was smooth enamel surface; EFG was an acceptable surface smoothness with very fine scratches; TCPG was surface with slightly coarse scratches, whereas TCG was surface with sever roughness and coarse scratches that can be seen by a naked eye. The operating time for cleanup with EFG was the lowest value among the four techniques (22.116 s) and significantly (P < 0.05) shorter than the TCPG and EFPG. Conclusions: The enhance finishing and polishing systems were considered as efficient techniques for removing the remnant adhesive materials after bracket debonding leaving a smooth surface with little or no scratches with the shorter operating time in EFG among the four techniques, whereas TCG was the worst one as it left the enamel surface with wide, deep grooves and scratches, and it is advised to stop and avoid using it anymore.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"500 - 508"},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43982864","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}

Materials and Methods: The research type was an experimental study; the method was carried out by designing the addition of some modified components to the therapy device for the calibration of the sensors in terms of measuring the increase and decrease in the temperature repeatedly three times. The temperature increase and decrease time recorded was the duration every 30 min for each session. The data obtained were then processed using the interrater reliability statistical test with interclass correlation coefficient (ICC), to see whether a measuring instrument (device) has adequate and accurate stability. Results: The results of measurements were analyzed using interrater reliability statistical tests with ICC and measuring from the mean value of both the increase and decrease in temperature with the analysis of the Mann–Whitney test Asymp Sig. 2 (tailed) of 0.860, which means it can be assumed to be the same or not different. The result showed that the ICC single measures on the LM35 was 0.894, whereas the ICC single measures on the thermocouple was 0.887. The ICC value of single measures on the LM35 was 0.999, whereas the ICC value for single measures on thermocouples was 0.993. Conclusions: It can be concluded that there was no difference between the value of increased and decreased temperature using the LM35 sensor or thermocouple. It can be assumed that the results are the same and that the ICC value category for the LM35 sensor and the thermocouple is very reliable and has high stability.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"468 - 474"},"PeriodicalIF":0.7,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47784518","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}

Materials and Methods: In this in-vitro study, nHAp was prepared using the microwave-accelerated wet chemical synthesis method and nCH was made by the ionic gelation technique. The particles were characterized separately under dynamic light scattering and made into a paste by mixing them at a ratio of 1:1, which was further analyzed using Fourier-transform infrared spectroscopy (FTIR). Dentin slabs were prepared from 32 extracted human molars and subjected to erosion by exposing to 3% citric acid for 5 min. They were divided into four groups by convenience sampling method (n = 15): group I-control (no treatment); group II-nHAp; group III-nCH; group IV-nHA–nCH paste. All dentin samples were treated according to their respective groups by the active application of pastes using microbrushes for 1 min everyday for 14 days. Later, the samples were subjected to FTIR and scanning electron microscopy and energy dispersive X-ray spectroscopy (SEM-EDX) analysis. Statistical analysis was done using one-way analysis of variance (P < 0.05). Results: SEM-EDX revealed complete occlusion of dentinal tubules in the nHA–nCH group with HAp deposits on the surface. The Ca/P ratio of various groups was significantly different from each other (control group-1.05, nHAp-1.64, nCH-1.14, and nHA–nCH-1.71) (P < 0.05). The FTIR spectra marked the presence of amide I peak in nCH and nHA–nCH groups, indicating collagen stabilization.

Initially, a point drill of 1.5 mm diameter was used to initiate the osteotomy preparation to the depth of the implant length. After that, sequential screw-shaped bone expanders were used to expand the osteotomy progressively rather than cutting to the desired width of the implant. Finally, an implant was placed with an insertion torque of 35–40 N-cm. At the third month, a final prosthesis was placed and excellent esthetic was achieved. Conclusively, ridge split and expansion technique is a simple, less-invasive, and viable alternative to modify the ridge to make the prosthetic-driven implant placement rather than bone-driven and screw-shaped bone expanders to avoid the bone augmentation procedure and to reduce the overall treatment time.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"422 - 426"},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41532093","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 purpose of this systematic review was to assess the clinical performance of the use of short implants on complete-arch implant-supported fixed dental prostheses and to compare their design with the in-vitro study. Materials and Methods: The PubMed database of the United States National Library of Medicine and EBSCOhost Research Databases were used as electronic databases, and a literature search was accomplished with a personal computer on articles published in English from January 2010 up to and including August 2020. Articles available online in electronic form before their publication in material form were considered eligible for inclusion in the present article. Results: The electronic search in both databases (PubMed and EBSCOhost) provided a total of 6779 titles and abstracts that were deemed potentially relevant to the influence of the short implant on a fixed complete denture. During the manual search of dental journals, 57 titles and abstracts were examined. In the second phase of study selection, the complete text of 1028 articles was retrieved and subjected to scrutiny. Throughout this procedure, 70 articles were obtained and the rest were excluded. Finally, the remaining 15 articles met the study inclusion criteria and were approved by all reviewers. Short implants offer benefits in terms of less invasive surgery, ease of handling, and reduced risk of damaging anatomical structures. Short implants can also be used in the rehabilitation of edentulous jaws. Avoiding or minimizing the length of the cantilever in dental implants is an important rule for the long-term success of implant treatment, including the rehabilitation of an edentulous jaw using an implant-supported fixed denture. The location of placement and the number of short implants are very influential in reducing the risk of excessive stress on the peri-implant bone. Conclusion: Short implants are potential alternatives to rehabilitating edentulous jaws, whether combined with standard size or longer implants or “All-on-short” as a whole. Further studies are still needed to obtain a guideline for the use of short implants to rehabilitate edentulous patients.","PeriodicalId":16138,"journal":{"name":"Journal of International Oral Health","volume":"14 1","pages":"331 - 341"},"PeriodicalIF":0.7,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41746978","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}
