Purpose: This study was conducted to understand the environment of dental clinics based on dental management survey data and, in particular, to analyze the management status according to the dentist’s years of practice to prepare basic data for the dentists’ year of practice gap and improvement of the dental business. Methods: We surveyed members of the Korean Dental Association on subjective difficulties in management and the rate of change in sales, operating expenses, and operating profits, and analyzed the results. Results: As a result, there were clear differences in the difficulties of dental management and sales patterns depending on the dentist's years of practice. Conclusions: At a time when dental operations are becoming more diverse, there is a need to find ways to improve through dental management research. In addition, through future research on differences between generations of dentists, it will be necessary to understand each other's positions and communicate smoothly to resolve difficulties within the dental community.
1. Purpose : This study aimed to investigate the differences in bone regeneration capacity following extraction between a control group without biomaterial placement and experimental groups where biomaterials were inserted (including xeno graft, synthetic bone-containing collagen plugs, and collagen plugs). 2. Materials and Methods : Bilateral extraction of maxillary first premolars or second premolars was performed, dividing the rabbits into four groups [① Group 1 :no bone graft or collagen plug inserted, ② Group 2: collagen plug inserted after extraction, ③ Group 3: collagen plug containing synthetic bone inserted after extraction, ④ Group 4: xenograft material inserted after extraction]. After euthanized the rabbit, Four and eight weeks postoperatively, the extent of bone formation were evaluated histologically and radiographically. 3 Results : The degree of new bone formation using histological analysis showed higher results in both the control groups at weeks 4 and 8, although not statistically significant. Across all groups, higher bone formation was observed at 8 weeks compared to 4 weeks. In radiological analysis using micro CT, Bone Mineral Density (BMD) and Bone Volume/Tissue Volume(BV/TV) were highest in Group 4. Trabecular bone thickness(Tb.Th) was highest in the control group, but not statistically significant. 4. Conclusion : In all groups, the degree of new bone formation at 4 and 8 weeks did not show statistically significant differences histologically and radiologically.
Purpose: This study aims to identify the utilization of claimed dental implants and the related factors in South Korea using the Anderson behavioral model. Materials and Methods: This study used the Health Checkup Cohort DB, claimed data from the National Health Insur ance Service (NHIS), to identify changes in the utilization of dental implants and related factors. The study population was selected as 75 years old because they were covered by NHIS since the first year, 2014. Finally, the sample subjects in the analysis were 63,880. The data was analyzed using IBM SPSS Statistics for Windows, version 26.0 (Statistical Package for the Social Sciences 26.0. SPSS Inc. Chicago, IL, USA). Results: The dental implant utilization rate of the study population increased continuously, from 3.4% in Phase 1 to 6.3% and 7.0% in Phase 2 and 3, respectively. The significant differences by region, insurance type, and disability were shown in Phases 1 and 2 (p<0.05), but it was insignificant in Phase 3 (p>0.05). In the fully adjusted logistic regression model, the probability of using dental implants was 1.9 times higher in the higher Phase than the others. The people who had annual oral examinations showed a two times higher possibility of having dental implant surgery. Conclusions: It is necessary to review the recent claiming trends and related factors before the decision-making for cover age, especially dental coverage with huge effects, such as dental implants.
Dens invaginatus is a developmental anomaly that occurs when the enamel organ is invaginated into the dental papilla before the process of calcification during tooth development. Dens invaginatus exhibits various anatomical variations, and these structural changes can complicate treatment. For effective management of dens invaginatus, it is crucial to accurately understand the internal structure of the tooth and to establish an appropriate treatment plan. Cone-beam computed tomogra phy (CBCT) has proven to be a valuable tool for three-dimensional reconstruction of the tooth. This case report presents a maxillary lateral incisor with pulpal necrosis and periapical periodontitis. The case involves dens invaginatus characterized by a separate tooth structure, diagnosed using CBCT, and a treatment plan was established accordingly. For treatment, a dental microscope was used to remove the internal structure of the tooth, followed by filling with mineral trioxide aggregate (MTA).
This study evaluated the effects of silver diamine fluoride (SDF) and potassium iodide (PI) on carious dentin. The antibac terial efficacy, surface hardness, and bond strength of resin-modified glass ionomer cement (RMGI) were assessed. Dentin specimens were prepared and subjected to artificial caries formation. The antibacterial effect of SDF/PI was compared to sodium fluoride varnish using Streptococcus mutans colony counts. Surface microhardness was measured using the Vickers hardness test. Shear bond strength of RMGI to treated surfaces was evaluated after thermocycling. Results showed that SDF/ PI had superior antibacterial effects compared to NaF varnish. Surface hardness significantly increased one week after SDF/ PI application. While SDF/PI treatment did not immediately affect RMGI bond strength to carious dentin, delayed bonding after one week significantly improved bond strength. These findings suggest that SDF/PI is effective in arresting caries and enhancing remineralization of carious dentin. The study also indicates that delaying restoration placement for one week after SDF/PI application may be beneficial for improving bond strength. This research provides valuable insights into the clinical application of SDF/PI for caries management and subsequent restorative procedures.
