Purpose: We analyzed to find out prognostic factors in the conservative treatment for the plantar fasciitis. Materials and Methods: The data were collected from 145 patients, 159 feet (M:F = 51:108) with conservative treatment and analyzed for possible prognostic factors : sex, age of onset, the duration of symptom before treatment, pain score before treatment, the duration for symptom remission, medication period, calcaneal pitch angle, and presence of calcaneal spur. Results: The duration of symptom before conservative treatment is affected to the prognosis, and the borderline of the effective period was about 6 months. Conclusion: With the conservative treatment of the plantar fasciitis, we found that (1) the duration of symptom before the conservative treatment was a prognostic factor, and (2) if the period before the conservative treatment was more than 6 months, the other treatment option such as surgery should be considered for this chronic group.

The aim of this study is to evaluate the effect of light intensity variation on the polymerization rate of composite resin using IB system(experimental equipment designed by Dr. IB Lee) by which real-time volumetric change of composite can be measured. Methods: Three commercial composites [Z100(Z1), AeliteFil(AF), SureFil(SF)] were photopolymerized with Variable Intensity Polymerizer unit (Bisco, U.S.A.) under the variable light intensity (75/150/225/300/375/450㎽$^2$) during 20sec.(omitted)

Objectives : The propose of this study is to find out the clinical application of conservative treatment for SLAP lesion. Methods : We examined 2 patients with SLAP lesion who admitted Jaseng Hospital of Oriental Medicine. The patients were treated by conservative treatments including herbal mixture, acupuncture, pharmacupuncture. Results : In this study, in the end of continuous conservative treatment, patient's shoulder pain has improved. Visual Analog Score(VAS) were also decreased. Conclusions : A conservative treatment for SLAP lesion was effective in restore of functional activities, but usefulness of this treatment needs more study.

I. Objectives Endodontic disease is caused primarily by bacteria that interact with periradicular host from the root canal system. Chlorhexidine gluconate is known to effective to eliminate Enterococcus faecalis which resists to other intracanal medicaments. The aim of this in vitro study was to develop a slowly releasing root canal disinfectant using using chlorhexidine gluconate and chitoic acid. II. Materials and Methods Three different group were prepared with different drug release mechanism. In group A, paper points as used core material were loaded with 20% chlorhexidine gluconate.(omitted)

I. Objectives Intracanal medicament with antibacterial action is required to maximize the disinfection of the root canal system. The purpose of this study was to evaluate the efficacy of 2% chlorhexidine digluconate(CHX) and controlled release device(CRD) containing 20% CHX and chitosan coating, compared to calcium hydroxide as intracanal medicament against E. faecalis. II. Materials and Methods One hundred and twenty intact freshly extracted bovine incisors were used and were 0.5% NaOCl. Middle 1/3 portion of roots were sliced into 4mm thick section and cementum was removed using diamond burs and external diameter was approximally 6mm.(omitted)

The purpose of this study was to evaluate the efficiency of the four obturation techniques. In this study, eighty teeth were instrumented and randomly divided into 4 groups of 20 teeth each, according to the obturation techniques Group A was used with Microseal. in Group B, Thermafil. in Group C, continuous wave techniques, in Group D cold lateral condensation methods were used. After obturation, the teeth were taken a digital radiograph in mesiodistal and buccolingual directions to study the quality of the obturation.(omitted)

Endodontic rotary NiTi(Nickel-Titanium) files have several advantages, but they also have some problems. Fracture of instrument is the one of the problems. Cyclic fatigue fracture may not give a previous sign(ex, bending or distortion of the files) before it happen. It is affected by various factors. This study investigated time which takes for cyclic fatigue fracture to happen and fracture patterns with regard to different NiTi files and pecking motion.(omitted)

In recent years, the use of Microtomograph in dentistry were proposed and its applications are increasing. The purposes of this study is to evaluate the micro leakage in Class V restorations by using Microtomograph and to compare with other leakage test methods. Using high speed round bur, Class V cavities were prepared to the buccal sides of sixty extracted human upper premolars and randomly distributed to 4 experimental groups and restored as follows.(중략)
