The exact incidence of esophagitis in gastroesophageal reflux disease (GERD) remains poorly understood in Korea. To determine incidence of esophagitis in GERD, from August 1988 to July 1993, endoscopy, esophageal manometry with Bernstein test, and ambulatory 24 hour esophageal pH monitoring were carried out in a group of 349 patients with symptoms of heartburn or noncardiac chest pain. Based on these studies, 151(40%) patients had some degree of GERD and pstients were categorized as having: pathologic reflux, 98 patients; symptomatic reflux, 42 patients; and sensitive mucosal reflux, 11 patients. Among 151 patients with GERD, 27 patients(18%) had some degree of esophagitis. In conclusion, 40% of patients with symptoms suggestive of GERD have GERD. GERD is divided into subgroups; pathologic reflux, symptomatic reflux, and mucosal sensitive reflux. Less than 20% of GERD have esophagitis or esophageal mucosal injury and these low incidence of mucosal injury in Korean may be due to increased esophageal mucosal resistance.

2.A study on the correlationship of submentovertex view and lateral cephalogram measurements.
Korean Journal of Orthodontics 1996;26(4):413-421
Cephalometric measureements have disadvantage of representing cranio-facial structures in two dimension only and therefore they pose limitations in describing three-dimentional structures of cranio-facial region. More interests have been put on the correlation between the two planes. This study evaluated correlations between facial type score, which allows effects on malocclusion, growth change prediction and establishment of treatment method and prognosis, and measurements from submentovertex view. Cephalometric view and submentovertex view were taken of skeletal Class I adults with optimal profile and correlations between them have been observed. Following results were obtained: 1. To learn about factors that influence average condylar angulation, FACE, INT-CO-ANG, MN-CORPUS, CON-RATIO, GON-RATIO, MN-RATIO were used as variables and underwent multiple regression analysis. As a result, the following equation was obtained : CON-AVE=.l73(FACE)-.322(INT-CO-ANG)+36.34(GON-RATIO) +.420(MN-CORPUS) (R2=.85451) 2. The following equation was obtained concerning facial type score. FACE= .050(CON-ANG)+.023(INT-CO-ANG)-.075(MN-CORPUS)(R2=.31547) 3. Among the submentovertex measurements, MN-CORPUS, CON-RATIO, GON-RATIO, MN-RATIO showed close correlations. (P<0.05) 4. Average condylar angualtions were 23.37degrees on the right and 20.71degrees on left. There was a difference between the two. FACE: facial type soore. CON-ANG: mean value of condylar angulation. CON-AVE: mean value of Rt. Lt condylar angulation. INT-CO-ANG: angle between Rt. Lt condylar axis. MN-CORPUS : angle formed between RT. Lt gonion & pogonion. CON-RATIO: lntercondylar distance/mandibular body length. GON-RATIO: intergonion distanoe/mandibular body length. MN-RATIO: lntermylohyoid distance/mandibular body length. MX-RATIO: intermaxillary tuberosity distance/ANS-PNS distance.

Accompanying to the development of the knowledgment of mechanism and pathology of recurrent dislocation of the shoulder, accurate diagnostic tools to detect that pathology have been developed. During the period from May 1990 to May 1992, we treated 28 cases of recurrent anterior dislocation of the shoulder. Twenty-eight cases were examined with C.T. arthrography before the operation. Among the 28 cases, we identified the Bankart lesion in 20 cases by C.T. arthrography, and in 21 cases intraoperatively. We concluded that the C.T. arthrography is an accurate method for confirming the clinical diagnosis of recurrent dislocation of the shoulder and to be helpful in detecting the Bankart lesion and its severity or pathologic findings.

PURPOSE: The purpose of this study was to identify the association between Sasang constitution and type A/B personality. METHOD: The subjects for this study were 113 Korean adults living in Kangwon Province, the northeastern part of Korea. The data were collected from March 10 to April 13, 2002 using a structured questionnaire. The instrument for this study were QCSS II (Questionnaire for Sasang Constitution Clsssification II) by Kim et al.(1996), and the Revised Type A/B personality by Eysenck & Fulker(1983). The data were analyzed through the SPSS 10.0 for Windows program using frequency, percentage, x2-test, ANOVA, and Pearson correlation coefficient. RESULTS: The results of the study are as follows: 1. Of 113 Korean adults, the portion who were Taieum-in, Soeum-in, Soyang-in was 39.8%, 34.5%, 25.7% respectively. 2. For type A/B personality, mixed type was most common, 19.4% of the participants were of type B and 8.0%., type A. 3. For type A/B behavior, mixed type was most common at 47.8% and type A was 2.7%. 4. There were statistically significant differences in the Sasang constitutional type according to BMI (F=14.542, P<.001), and alcohol consumption (F=4.256, P<.018). 5. There were significant difference between type A/B personality and BMI (F=3.592, P<.032). 6. The data shows correlations between BMI and amount smoked per day (r=2.74, P<.004), between BMI and alcohol consumption (r=-.303, P<.008), between BMI and Sasang constitutional type (r= -0.592, P<0.0001), between BMI and type A/B personality (r=285, P<.011), between amount smoked per day and alcohol consumption (r=.-361, P<.001), between alcohol consumption and Sasang constitutional type (r=-.306, P<.019), between perceived health state and type A/A personality (r=.246, P<.011). CONCLUSION: According to the above findings, it can be concluded that further research is need to understand the Sasang constitution for the discipline of Nursing and for nurses to prepare nursing protocols relevant to Sasang constitutional care. Also, Sasang constitution has to be considered in research and practice in the health care delivery system.

The purpose of this study was the long-term clinical and radiological evaluation of conservatively treated condylar fractures in children. This study was therefore undertaken to analyze the long-term effects of treating condylar fractures in children with conservative therapy in order to resolve the controversial question of whether complete remodeling occurs in this age or, if not, whether it is more likely to be associated with certain types of fracture or with other factors. This study was based on a series of 11 consecutive children and adolescents, aged between 3 and 15 years, with fractures of the condylar process who had been treated with conservative therapy at the Department of Oral and Maxillofacial surgery, Inha University Hospital, Inchon, Korea. All patients underwent a clinical investigation with special emphasis on Temporomandibular joint function and facial asymmetry. The patients also underwent a radiologic investigation, focusing on fracture remodeling and symmetry of mandible. It consists of panoramic radiograph, PA and lateral cephalogram and 3-D CT. No patient described impaired temporomandibular joint(TMJ) function or pain on the affected side. 2 of 8 (25%) unilateral and 1 bilateral fractures show slight facial asymmetry. Despite apparently excellent recovery of function, there were marked remodeling changes evident on the CT scan. Such changes are not usually evident on panoramic radiograph. Radiologic investigation showed incomplete remodelling(54.5%) and asymmetry of the mandible (27.3%) in some patients. Conservative treatment of condyle fracture in children results in satisfactory long-term outcome of jaw function despite a relative high frequency of radiologically noted aberrations.

STATEMENT OF PROBLEM: Porcelain veneers have become a popular treatment modality for aesthetic anterior prosthesis. Fitting porcelain veneers in the mouth usually involve a try-in appointment, which frequently results in salivary contamination of fitting surfaces. PURPOSE: An in vitro study was carried out to investigate the effect of silane treatment timing and saliva contamination on the resin bond strength to porcelain veneer surface. MATERIAL AND METHODS: Cylindrical test specimens (n = 360) and rectangular test specimens (n = 5) were prepared for shear bond test and contact angle analysis. Whole cylindrical specimens divided into 20 groups, each of which received a different surface treatment and/or storage condition. The composite resin cement stubs were light-polymerized onto porcelain adherends. The shear bond strengths of cemented stubs were measured after dry storage and thermocycling (3,000 cycles) between 5 and 55 degrees C. The silane and their reactions were chemically monitored by using Fourier Transform Infrared Spectroscopy analysis (FTIR) and contact angle analysis. One-way analysis of variance (ANOVA) and Dunnett' multiple comparison were used to analyze the data. RESULTS: FT-IR analysis showed that salivary contamination and silane treatment timing did not affect the surface interactions of silane. Observed water contact angles were lower on the saliva contaminated porcelain surface and the addition of 37 percent phosphoric acid for 20 seconds on saliva contaminated porcelain increased the degree of contact angle. Silane applied to the porcelain, a few days before cementation, resulted in increasing the bond strength after thermocycling. CONCLUSION: Within the limitation of this study, it can be concluded that it would be better to protect porcelain prosthesis before saliva contamination with silane treatment and to clean the contaminated surface by use of phosphoric acid.
