: Cone beam CT (CBCT) can evaluate the three-dimensional morphology of the target sites for diagnosis and the surrounding tissues, and also allows measurement of the distance and angle from the specified sites. Bone defect morphology inferred from dental radiographs may differ from the actual bone defect state during surgery. When performing periodontal tissue regeneration therapy, it is impor-tant to know the exact state of bone loss in advance for ensuring the success of the surgery. Therefore, at our department, it is obligatory to obtain a CBCT image in patients scheduled for periodontal tissue regeneration therapy, prepare a model with a 3D printer, and hold a conference on periodontal tissue regeneration therapy prior to the treatment. We report on the flow of the periodontal tissue regeneration therapy conference in our course and for the two cases in which the therapy was actually undertaken. These cases are of patients with a vertical bone defect. A preoperative conference was held based on the CBCT images of the operation site, 3D models, and clinical protocol data. The 3D model almost reproduced the actual bone defect. For patients undergoing periodontal tissue regeneration therapy, CBCT imaging and preparation of a 3D model with a 3D printer can allow the surgeon to obtain a grasp of the bone defect form at the surgical site in advance and allow a satisfactory conference to be conducted before surgery. Our results indi-cate that the operation can be performed safely and effectively. Conducting a satisfactory conference before surgery is also a useful means for training young dentists and explaining to patients.

: Diagnosis and treatment outcomes of periodontal disease have typically been evaluated using biomedical data such as probing depth. Recently, however, there is greater research focus on quality of life (QOL) in medical treatment. This study therefore aimed to clarify the relationship between periodontal disease severity and oral health-related QOL. Information was extracted from medical records of patients aged 30-64 years and who visited Nakai Dental Office for the first time between November 2014 to July 2017. Severity of periodontal disease was diagnosed by results of a baseline periodontal examina-tion, and then scored in accordance with the Community Periodontal Index and classified into four groups: (C, P1, P2, P3). QOL was assessed using the total score and seven subdomain scores from the Oral Health Impact Profile Short Version (OHIP-14). The Kruskal-Wallis test was then used to compare among the four groups of the total score of OHIP-14 and the seven subdomain scores. Comparison of the groupsʼ total OHIP-14 scores showed significant differences between P1 and P3 and between P2 and P3, while P3 had a significantly higher score than other groups. Comparison of the groupsʼ OHIP-14 subdomain scores showed significant differences between P1 and P3 and between P2 and P3 for “functional limitation,” and between P1 and P3 for “psychological discomfort,” while P3 had a significantly higher total score than other groups. There were no significant between-groups differences for the other five subdomain scores. Functional limitations was assessed subjectively as difficulty in chewing and food getting caught between teeth. Anxiousness and negativity regarding the dental problem were reported among psychological discomfort. Oral function appeared to subjectively decrease, while discomfort increased with worsening of periodontal disease. In general, QOL worsened. Among the subjects, severity of periodontal disease was associated with oral-health-related QOL. It was suggested that patients with more severe periodontal disease had subjectively more impaired oral function, more discomfort, and lower QOL.

: We report the case of a tuberous sclerosis complex (TSC) patient with severe chronic peri-odontitis, in whom we undertook intensive non-surgical periodontal treatment under general anesthesia and continuous supportive periodontal therapy (SPT) under intravenous sedation. The 43-year-old male patient visited our clinic with the chief complaint of tooth movement. He had never received periodontal treatment because of his maladaptation to dental treatment. Periodontal examination revealed gingival inflammation with easy bleeding, deep periodontal pockets with pus discharge, and intense tooth mobility.
