5 Year Cumulative Survival Rate of Composite Resin Restorations in Permanent First Molars / 대한소아치과학회지

The purpose of this retrospective study was to evaluate the survival rate of composite resin restorations in permanent first molars in pediatric patients focusing on the influence of risk factors related to patients and teeth.172 patients (6 – 12 years old) who had their permanent first molars restored with composite resin from July 2010 to July 2012 were investigated. From the dental records, the influence of the risk factors on the survival of restorations was assessed. Location of teeth, classification of cavities, patients' age and caries risk were included as risk factors in this study. The caries risks of patients were evaluated by the value of the decayed-missing-filled teeth index with the records of patients taken at 5 years old.Among 354 restorations, 272 restorations retained and 82 restorations were replaced. The overall cumulative survival rate at 5 years was 73.9%. The main reason for replacement of restorations was secondary caries (81.7%). Patients with older age group and with lower caries risk group showed higher survival rate of restorations. No statistically significant influence was detected between the survival rates and the possible risk factors : location of teeth, patients' age and caries risk. The survival rate of restorations was significantly affected by the classification of the cavities (p = 0.002).

Scoring System for Screening Fitz-Hugh-Curtis Syndrome in Childbearing-aged Women who Visit the Emergency Department with Upper Abdominal Pain

PURPOSE: Fitz-Hugh-Curtis syndrome (FHCS) is a perihepatitis associated with pelvic inflammatory disease. Due to difficulty in diagnosis of FHCS on initial evaluation, we developed a reliable scoring system for screening FHCS using clinical variables. METHODS: We reviewed the registries of women of childbearing age who presented with upper abdominal pain in an urban emergency department from April 2008 to October 2010. Using multivariate analysis, along with 95% confidence interval (CI), we identified the statistically significant predictor variables that affected the FHCS. Using the results, we developed the scoring system for FHCS. Performances of each score were evaluated using the receiver operating characteristics (ROC) curve. RESULTS: A total of 361 eligible women of childbearing age were enrolled in our study. Fifty patients were diagnosed as FHCS. The significant factors for FHCS were as follows: pain onset for more than two days, history of abortion, unmarried woman, coitus within four weeks, migrating pain, absence of gastrointestinal symptoms, absence of urinary symptoms, and elevation of C-reactive protein. We assigned a score of 1 or 2 to each variable using the beta-coefficients. The ROC areas of the scoring system were 0.920. Patients were categorized as low (score 0~4), intermediate (score 5~7), and high (score 8~10) risk groups; 75.0% of high, 18.3% of intermediate, and 1.0% of the low risk group were diagnosed as FHCS. CONCLUSION: We developed a novel scoring system for screening FHCS of women of child-bearing-age who had presented with upper abdominal pain. Use of this scoring system will allow for easier screening for FHCS in women of child-bearing age.
