ABSTRACT: Regeneration of lost periodontium is the ultimate goal of periodontal therapy. Bone grafts, guided tissue regeneration, and application of growth factors are used for periodontal regeneration. This study aimed to evaluate the clinical efficacy of a new, injectable calcium phosphate bone cement (CPC) in human periodontal intrabony defects. Thirty subjects (mean age, 53.4 +/- 9.1 years) with periodontitis and narrow intrabony defects were enrolled in the study. Subjects were classified randomly into the CPC graft group (N = 15) or the open flap debridement (OFD) alone group (N = 15). Clinical measurements were performed at baseline and at 3, 6, 9, and 12 months; radiographs were taken at baseline, 2 weeks, and 6 and 12 months after surgery. The Student t test was used for statistical analysis. In the CPC group, six cases showed exposure or loss of the CPC within 12 months, whereas the remaining nine cases (CPC-R group) showed no adverse reaction, including infection or suppuration. Overall, CPC-R and OFD treatment groups exhibited a significant reduction in probing depth and a significant gain in clinical attachment level at 3, 6, 9, and 12 months compared to baseline values. However, there were no significant differences in any of the clinical parameters between the groups. In the CPC-R group, radiographic bone level gain appeared to be greater than in the OFD group. The present study failed to demonstrate any superior clinical outcomes for the CPC group compared to the OFD group; however, radiographs revealed more favorable results in the CPC-R group. The filling volume and stiffness of CPC may compromise the clinical outcomes for periodontal intrabony defects.Journal of Periodontology 02/2008; 79(1):25-32. · 2.40 Impact Factor

ABSTRACT: This clinical study was performed to evaluate the clinical and radiographical outcomes of a ready-to-use EMDOGAIN^[○!R]-gel. Twenty one periodontitis patients (33 sites) with infrabony defects were selected. After initial treatment, clinical parameters such as probing depth (PD), clinical attachment level (CAL), bleeding on probing, tooth mobility and gingival recession were recorded and radiographs for bone level measurement were taken at baseline. Examinations were repeated 8 and 18 months post-operatively. The mean PD was 7.68 mm at baseline, 3.69 mm at 8 months, and 3.70 mm at 18 months. The mean gain of CAL was 2.50 mm at 8 months and 2.70 mm at 18 months, and the radiographic measurements showed a mean bone level gain of 1.17 mm at 8 months and 1.69 mm at 18 months. This series of cases demonstrated a statistically significant reduction of PD, gain of CAL and bone level at 8 months and 18 months.

ABSTRACT: Recently, the persons concerning about halitosis are increasing. For special diagnosis and treatment for halitosis, Kagoshima University Medical and Dental Hospital established Oral Malodor Clinic in 1997. Over 800 patients visited the clinic in 8 years. In this review, the diagnosis and treatment system of halitosis in our clinic is discribed. The oral malodor was estimated by the analysis of the volatile sulfur compounds (VSC) level by gas chromatograph and the organoleptic analysis. The interview using the questionnaire and oral examination was also used for diagnosis. The 801 patients (278 male and 523 female) were classified into physiologic halitosis (n=147: 18.4%) and oral pathologic halitosis (n=332: 41.5%), extraoral pathologic halitosis (n=41: 5.1%), pseudo-halitosis (n=254: 31.7%), and halitophobia (n=22: 2.8%). The treatment was done according to the treatment needs for breath malodor. In the treatment of halitosis, oral hygiene including tongue cleaning is the most important. For the patients with periodontal disease, periodontal therapy is also needed. In patients with no or less halitosis, some patients disagree with the results. For such patients, repeated examinations are needed. Extraoral pathologic halitosis or halitophobic pateients need to be referred to a specialist. For the treatment of halitosis, accurate diagnosis is important.
