Application of FV with a flavoring agent promotes comfort and acceptance by patients, especially children, and facilitates an effective treatment time. Objective: Flavored FV with a pleasant flavor should allow a faster treatment time, especially with children. The aim of this research was to study basic FV formulations containing different flavors of essential oils (LorAnn) and variations in the concentrations of flavor oils to determine the optimum formulation to enhance the in vitro fluoride release time. Methods: The independent variables were the flavors (apple, melon, and peppermint) and the concentrations (1, 1.5, 2, or 2.5%) of the flavor that gave the best fluoride release (peppermint). The amounts of fluoride ions released in 6 h into deionized water were assessed at 37°C using an ion-selective electrode with the addition of fluoride total ionic strength adjustment buffer solution to strengthen the ion reading. The cumulative ion release was analyzed for normality and equality of variance, and the means were compared using a general linear model test and Statistical Package for Social Sciences version 23.0 software. The significance level was set at α = 0.05. Results: At the same concentration of 2% for the apple, melon, and peppermint flavors, the peppermint formulation gave the best fluoride release, at 173.22 mg/L. A peppermint oil concentration of 2.5% showed the highest fluoride ion release, at 178.95 mg/L. Conclusions: The addition of peppermint flavor oil at a concentration range of 1—2.5% revealed an increasing release of fluoride ions with an increasing peppermint oil concentration. Further investigations are still needed using artificial saliva to replicate actual conditions in the oral cavity.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"5 1","pages":"133 - 137"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44549353","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 early stages of SSc are challenging to diagnose because of their similarity to other autoimmune conditions. Inappropriate SSc treatment can increase the risk of disability, morbidity, and mortality. Different pathogenesis pathways incur various manifestations in the skin and the oral cavity. In this scenario, dentists play an essential role in managing oral SSc manifestations. Proper oral examination, diagnosis, and therapy help to increase the confidence and patient’s quality of life. Case Report: A 24-year-old female patient with SSc was referred from the Internal Medicine Department to the Oral Medicine Department because of lip soreness for 2 weeks, resulting in difficulty eating and opening the mouth. A complete anamnesis and clinical examination were done. The patient was diagnosed with an oral ulcer caused by SSc, cheilitis exfoliative, drug-induced pigmentation, xerostomia, and acute pseudomembranous candidiasis. The oral lesion in this patient was concluded as an oral ulcer caused by SSc because the patient had already stopped using methotrexate for 2 weeks before the ulceration appeared. The oral treatment included sodium chloride (NaCl 0.9%), vaseline album, hyaluronic acid mouthwash, and nystatin. Oral lesions had a significant improvement after 3 days of treatment. Conclusion: The SSc manifestation that appeared on the oral cavity of the patient as microstomia, tongue stiffness, and oral ulcer resulted in inadequate clinical examination, and diagnosis. Treatments for this oral SSc were challenging.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"5 1","pages":"148 - 154"},"PeriodicalIF":0.0,"publicationDate":"2021-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44200842","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 content of cigarettes can affect the composition of saliva, such as the levels of magnesium, calcium, and phosphate. Objectives: The purpose of this study is to compare gingival health status and salivary magnesium levels in smokers and nonsmokers. Materials and Methods: This research is a descriptive study based on a cross-sectional approach. Forty-two subjects participated in the study which was divided into two groups: smokers and nonsmokers. A purposive sampling technique was used, and a questionnaire was disseminated to collect data on age, gender, number of cigarettes smoked per day, duration of smoking, and types of cigarettes consumed. Oral health status was measured using the Löe and Silness gingival index. Saliva was collected using the spitting method, and salivary magnesium levels were measured by atomic absorption spectrometry. The data analysis was performed using the independent sample t-test and the Mann–Whitney test. Results: The gingival index scores for the smokers and nonsmokers were 0.49±0.195 and 0.26±0.207, respectively. There was a significant difference between smokers and nonsmokers gingival index (P = 0.001). The salivary magnesium levels in the smokers and nonsmokers were 54.43±17.37 and 51.29±15.97 µg/dL, respectively. There was no significant difference in the levels of magnesium saliva between the smokers and nonsmokers (P = 0.428). Conclusion: The findings of this study indicate that the gingival index in smokers is higher than that in nonsmokers. However, the results showed no difference in salivary magnesium levels between the smokers and nonsmokers in this study.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"5 1","pages":"79 - 83"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47129339","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}

A filler particle size and composition affect the color change of the composite resin after polymerization despite the improvement in the chemical composition and filler of the composite resin. Objective: The effects of nanohybrid filler and submicron composite resin shade on color changes after polymerization were determined. Methods: Disc-shaped composite resin samples (diameter and thickness of 12 mm and 2 mm, respectively) were categorized into six groups, with each group containing 10 plates, according to the shade and type of filler (nanohybrid UD1, UD2, UD3; submicron OA1, OA2, OA3). Digital photographs were taken before and after polymerization. The changes in color (ΔEFNx01ab values) were determined using software via eLABor_aid. Result: Only the Micerium EHRi UD1 composite resin group exhibited ΔEFNx01ab < 3.3. The independent t-test revealed significant differences in the ΔEFNx01ab (P < 0.05) between the nanohybrid and submicron composite resins in all shade groups (A1, A2, and A3). One-way analysis of variance revealed significant differences in ΔEFNx01ab (P < 0.05) among A1, A2, and A3 between the nanohybrid and submicron composite resin groups. Tukey’s post hoc test revealed significant differences in ΔEFNx01ab (P < 0.05) for the Micerium EHRi UD1 group compared with those of the UD2 and UD3 groups, as well as in the case of the Tokuyama Palfique OA1 group compared with those of the OA2 and OA3 groups.

The super-elastic property of the nickel-titanium (Ni-Ti) file system provides advantages in preparation of curved root canals, as it can reduce the force on the root canal wall, increase centering ability, and reduce iatrogenic errors. Objective: The aim of this article is to determine the differences in preparation results of two reciprocal Ni-Ti files with and without glide path to the changes of root canal curvature. Materials and Methods: Twenty pieces of endodontic blocks (ISO# 15, 16 mm, 2% tapered) were divided into four randomly assigned groups. Group 1 (without glide path) and Group 2 (with glide path) were prepared with Wave One Gold (WOG). Group 3 (without glide path) and Group 4 (with glide path) were prepared with Reciproc Blue (RB). Each subject was explored using K-file #10. Glide path was prepared with ProGlider (PG) #16. Digital images of before and after the root canal preparations were taken using a digital camera with the same angle and distance settings. The before and after photos were superimposed on each other, and the transportation at the inner and outer root canal walls in the coronal curvature, apical curvature, and apical end points was measured with software. Results: No significant difference was found between changes in the coronal curvature using WOG and RB, with and without glide path (P > 0.05). The same result was observed between WOG and RB groups with glide path at each measurement point. Significant differences were found between changes in apical curvature and apical point in the inner wall using WOG and RB without glide path (P < 0.05). Conclusion: There were differences in root canal curvature prepared using WOG and RB on the apical region when prepared without glide path, but no differences were found when prepared with glide path at each point measurement.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"5 1","pages":"84 - 90"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43342793","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}

A certain feeding style is influenced by a parenting style. The high intake of foods containing sugar without parental control can increase the incidence of early childhood caries (ECC). Objective: The Objective of this article is to analyze the association of parenting styles and feeding styles on the occurrence of ECC among children aged 3–5. Methods: The research was an analytical cross-sectional study. Data were collected from 105 pairs of mothers and children, selected through the purposive sampling technique in Yogyakarta. Type of parenting and feeding styles was obtained through questionnaires given to mothers, whereas intra-oral examination was used to detect the ECC in children using the decay-missing-filling-teeth (dmf-t) index. Data were collected and analyzed using multinominal logistic regression with a statistical significance at P < 0.05. Results: The prevalence of ECC and dmf-t among children with permissive parents was highest (63.84%; 7.51+5.97) when compared with those with authoritarian parents (26.21%; 3.09+4.23). Those with authoritative parents was lowest (9.95%; 1.17+1.65). Authoritative parenting is associated with less consumption of cariogenic foods and low occurrence of ECC (P < 0.05). Conclusion: Parenting styles have a direct association with feeding styles and ECC. Children with authoritative parents have a highest benefit on lowest risk of ECC when compared with other counterparts.","PeriodicalId":32049,"journal":{"name":"Scientific Dental Journal","volume":"5 1","pages":"63 - 67"},"PeriodicalIF":0.0,"publicationDate":"2021-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43842560","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}
