Specific osteogenic markers, such as insulin-like growth factor (IGF-1), osteocalcin (OCN), Runt-related transcription factor 2 (RUNX2), and osterix (OSX), accompany osteoblast differentiation from an undifferentiated state to a functional state. IGF-1 hormones are the main regulators in growth, differentiation, and apoptosis in cells and tissues mediated by IGF-1 receptors (IGF-1R). Biomolecular technology aims to study nucleic acids and their regulation and expression of proteins. Techniques that can be used when analyzing proteins include the Bradford protein assay, immunocytochemistry, immunohistochemistry, sodium dodecyl sulfate–polyacrylamide gel electrophoresis, and the western blot test. To better understand the biomarkers of osteogenesis, the use of in-situ detection is suggested, such as immunocytochemistry and the western blot test. For this review, the author adhered to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) standards. The research examined 50 articles; only 4 articles were selected for this review. In the immunocytochemical test, IGF-1 expression was found in the nucleus and IGF-1R expression in the cell membrane, and it was found that RUNX2, OSN, and OCN are important for osteogenesis. During the western blot test, it was found that the addition of IGF-1 in dental stem cells could increase the expression of RUNX2, OSX, and OCN proteins. Based on this information, it appears that both immunocytochemistry and western blot tests can detect the main biomarkers of osteogenesis.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"6 1","pages":"10 - 17"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47217594","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}

OMP can be induced by various daily oral care products. Although common, some clinicians may not be familiar with OMP. In this case report, we describe a case of widespread OMP associated with toothpaste and mouthwash use. Case Report: A 40-year-old man presented with asymptomatic white lesions, with thin sloughing appearance in the whole oral mucosa. The patient was healthy, with no routine use of medications. The lesions were easily removed using a sterile gauze, with no subsequent erosion or ulceration occurring. The lesions were attributed to the use of sodium lauryl sulfate (SLS)-containing toothpaste and a mouthwash containing chlorhexidine (CHX) and essential oils. The patient was advised about the benign nature of the lesions. Discontinuation of SLS-containing toothpaste was suggested. Conclusion: OMP is commonly associated with the use of SLS-containing toothpastes and dentifrices and mouthwashes containing essential oils or CHX with the use of SLS-containing toothpastes and dentifrices and mouthwashes containing essential oils or CHX. Dentists must be able to identify OMP and provide appropriate patient education.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"6 1","pages":"53 - 57"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47174868","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}

Social and mass media have both positive and negative effects on adolescents’ behavior and social skills and therefore play vital roles in driving this behavior. Objectives: The purpose of this study was to assess the influence of film stars on smoking initiation and tobacco use among male adolescents aged 13–15 years in Chennai city, Tamil Nadu, India. Methods: The study adopted a cross-sectional design. In total, 200 students from schools that serve low-income households participated in the study. All the students completed a 20-item questionnaire on the perceived severity of smoking, perceived barriers to quitting, and factors affecting quitting. Results: None of the participants had a history of smoking. One (0.5%) participant stated that he smoked daily. All the participants agreed that exposure to media images of smoking behavior among their favorite film stars would not encourage them to smoke. In terms of peer pressure, one (0.5%) participant stated that he would accept a cigarette if offered one by a friend. Only descriptive information of the collected data was tabulated as the aim of the study was to collect the baseline data and not to test any prespecified hypothesis. Conclusion: In our study, peer pressure seemed to play more influence on the smoking initiation by adolescents than the film stars on mass media. Though all of them agreed that they would not be provoked by media images of film stars smoking, one participant was likely to initiate the habit on being offered by his friend. Hence, the evidence suggests the need for reorientation of research modalities to better identify early initiators of smoking.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"6 1","pages":"48 - 52"},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70843355","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 complete removal of these materials during root canal retreatment is crucial in order to ensure adequate disinfection. Due to the difficulty in accessing root canal ramifications, removal of these filling materials without damaging the teeth can be successfully achieved using endodontic solvents. Objective: The aim of this study was to evaluate the solubility of two types of root canal sealers in xylene used in endodontics. Methods: A total of 34 epoxy resin and bioceramic samples were stored for 72 h in an incubator to set. The samples were then immersed for 2 min in 1 mL of xylene. The excess xylene on the samples was drained with an absorbent paper and stored in an incubator for 24 h to dry. The pre- and post-immersion weight of the samples was measured using a digital analytical scale, then the weight difference between the groups was analyzed using the independent t test at a 5% significance level. Results: No significant difference was observed between the epoxy resin-based root canal sealer group and the bioceramic-based root canal sealer group (P ≥ 0.05).
