Purpose: The purpose of this study is to compare the cost of impacted tooth extraction in Korea and some OECD countries and ultimately use it as basic data for the future revision of the relative value of national health insurance. Materials and Methods: Costs of tooth extraction in Korea, Japan, the United States, Australia, the United Kingdom, Ger many, France, and Canada were investigated. The costs were investigated through the dental association or association of oral and maxillofacial surgery in each country with literature review. In countries such as Korea, Japan, and Germany, which have a universal health insurance system at the national level, a survey was conducted based on a data collection listing standard tooth extraction cost. The costs were compared using the price level of each country and Big Mac Index. Results: The classification and cost system for impacted tooth extraction were different in each country. Nevertheless, when comparing them by grouping them as similar as possible, the cost of impacted tooth extraction of Korea is lowest compared to some OECD countries. In addition, the cost is lowest even considering comparative price levels and the Big Mac index. Conclusion: In conclusion, we believe that the fees for impacted tooth extraction need to be appropriately adjusted to a level similar to that of OECD countries, reflecting various factors. It is also believed that changes and approvals for a new the tooth extraction cost system are needed.
Objectives: This study aims to investigate dental students' perceptions regarding the evaluation of clinical practice and to explore the factors influencing these perceptions. Methods: An online survey was conducted targeting third and fourth-year dental students from 11 nationwide dental schools. The survey focused on their perceptions of the accuracy and fairness of two clinical practices: 1) clinical clerkship in specialty clinics, and 2) direct patient care in pre-doctoral treatment centers. Additionally, the effects of different clerkship models (disciplinary block, longitudinal integrated), evaluation units (individual subject, integrated subject), and grading systems (grading, pass/fail) were assessed. Results: The overall perception of fairness and accuracy in clinical practice evaluation was found to be low. Students in disciplinary block clinical practice settings reported lower perceptions of evaluation accuracy and fairness compared to those in longitudinal integrated or mixed schedule types. Furthermore, the grading system influenced the perception of fairness and accuracy in the evaluation of clinical practices. Regarding direct patient care in pre-doctoral treatment centers, the evaluation units significantly impacted students' perceptions, although the grading system did not. Groups with grading systems showed lower perceptions compared to those with pass/fail or mixed evaluation systems. Conclusion: The study reveals that dental students perceive clinical practice evaluations as generally unfair and inaccu - rate, particularly within disciplinary block schedules. To improve future dental education, adopting longitudinal integrated schedules could be considered to enhance the perceived fairness and accuracy of clinical practice evaluations.
The purpose of this case report is to compare the mucosal change that occurs at the coronal aspect on the posterior teeth with commercial healing abutment (HA) and sealing socket abutment (SSA). A total of 4 cases are introduced in the pres ent case report. Two cases of immediate implant using HA (one premolar and one molar) and two cases using SSA (one premolar and one molar) method are compared. Intra-oral scanned stereolithographic (STL) images are used to compare the horizontal and vertical change before extraction and 6 months post-surgery. Less horizontal and vertical changes were observed when SSAs are used compared to HAs. With the aid of digital dentistry, SSA is a prompt and effective method to maintain peri-implant mucosal contour after the immediate implantation in the posterior site.
