PURPOSE: This study was aimed to investigate the frequency of different classes of partial edentulism and the most frequently used design components of conventional removable partial dentures. MATERIALS AND METHODS: 63 patients who were treated with removable partial denture in Kyungpook National University hospital for 2003 - 2006 were selected. A total of 76 removable partial denture frameworks were investigated. Kennedy classification was used to identify the class of partial edentulism. RESULTS: Results indicated that Kennedy class I removable partial dentures were the most frequently constructed. Most patients'cases were designed without modification areas. CONCLUSION: The most common type of direct retainer were the RPI clasp and RPA clasp in both maxilla and mandible. Lingual bar, linguoplate and anterior posterior palatal straps were the more frequently used mandibular and maxillary major connectors respectively. We did not have any case about Kennedy class IV patients.

BACKGROUND AND OBJECTIVES: Low concentration hypochlorous acid is known for being an endogenous anti-bacterial and anti-viral agent. Saline irrigation has been used as an adjunctive treatment for patients with chronic sinusitis. In this study, we tried to compare the effectiveness of hypochlorous acid and saline nasal irrigation to patients with intractable sinusitis after surgery. SUBJECTS AND METHOD: A total of 35 patients who had a frequent relapse of chronic sinusitis or had persisting symptoms post-surgically were recruited. The experimental group was given hypochlorous acid and saline nasal irrigation, while the control group was given saline nasal irrigation for eight weeks. The curative effects were assessed on the basis of the symptom score, nasal endoscopic score, bacterial culture, and inflammatory cytokines on the first day, fourth week, and eighth week after treatment. RESULTS: A total of 26 participants were assessed. The study finally consisted of 15 patients in experimental group and 11 in the control group. The symptom scores in the experimental group were substantially lower before, and after four and eight weeks of treatment. However, there was no specific difference in symptom score improvement between the two groups. The endoscopic score improved in experimental group (p<0.01). Similar tendencies were shown in the bacterial culture test of both groups. In the experimental group, the values of TNF-alpha, IL-8, and IL-1beta decreased in the fourth week, whereas they increased in the eighth week. CONCLUSION: Hypochlorous acid nasal irrigation may be to used as an alternative adjunctive treatment in addition to saline irrigation.
