The purpose of this study was clarify the problems on the program of selective endodontic practice course for 6 grade dental students at Showa University School of Dentistry based on the questionnaires after practice course in order to consider what is best program for selective endodontic practice course. Nine students who selected the endodontic course (2 at 2006 and 7 at 2007), were included in this report. The programs which we had planned on referring to the opinions of students were very satisfactory for 7 students and satisfactory for 2 students, but some problems remained. It is necessary to discuss the themes submitted on the questionnaires of students in future.
To improve the quality of the postgraduate clinical training program, there is a need to increase the number of patients who accept examination by dentist-in-training. To understand the tendencies of patients who accepts a dentist-in-training, the first medical examination patients who visited the Department of Comprehensive Dentistry of Showa University Dental Hospital from April 2003 to March 2006 were investigated. As the factors for classifying first medical examination patients, sex, age, main diseases, and visited month were categorized. The first medical examination patients who accepted a dentist-in-training [PT] were 18% of all patients who had visited the Department of Comprehensive Dentistry [PW]. There were twice as many female patients as compared to male patients for both PW and PT. The age distribution of the patients in PW was 20 s female > 30 s female > 50 s female > 60 s female > 20 s male > others, while it was 20 s female > 20 s male > others in PT. The number of patients categorized by primary diseases in PW were dental carious> periodontal disease > periapical disease > denture prosthesis, and dental carious > periodontal dis-ease > denture prosthesis > periapical disease in PT. To increase the number of patients who accept a dentist-in-training, it was concluded that the substantiality of the number of specialists who can diagnosis and conduct medical treatment for acute symptoms should be improved in the Department of Comprehensive Dentistry.
We reviewed 80 oral cancer patients reconstructed with free radial forearm flap for the past 18 years. The patients included 54 males and 26 females. Their average age was 58.9 years. According to classification by primary lesion, the tongue, floor of the mouth, and lower gingival were pointed out as the sites of predilection. According to the T classification, T2 was predominant. This surgical procedure was predominantly used for reconstruction of the tongue and floor of the mouth, and actually adopted in 49 cases. The survival rate of flaps was 93.7%. The cumulative five-year survival rate of patients who underwent reconstruction with radial forearm flaps was 79.1%. This technique proves to be useful because free radial forearm flaps can be widely used for reconstruction of the tongue and floor of the mouth, and postoperative course and the survival rate are satisfactory.
