Résumé
Background: Mandibular incisors are the smallest among the permanent dentition, with thin enamel and dentin. Intact teeth do not fracture easily while mastication. Objectives: To evaluate the fracture resistance of mandibular incisors after endodontic treatment and metal ceramic crown placement. Materials and methods: Eighty recently extracted intact mandibular incisors were divided into four groups of twenty each based on root canal treatment and crowns, intact natural tooth without RCT and crown preparation was used as control group. Each tooth was mounted separately in acrylic block and subjected to loading in universal load testing machine until fracture, results were analyzed by one-way ANOVA and Turkey’s multiple post hoc procedures.

Evaluation of fracture resistance of mandibular incisors before and after endodontic treatment and metal ceramic crown placement. IAIM, 2017; 4(11): 18-26. Page 19 Results: The results showed that Fracture resistance of teeth restored with metal ceramic crowns was very high when compared to the teeth without crowns (p<0.05).There was no statistically significant difference between intact and endodontically treated teeth (p>0.05). Conclusion: The study concluded that endodontic treatment and tooth preparation followed by metal ceramic restoration increased the fracture resistance of mandibular incisors.
Résumé
Background: Biliary dyskinesia is a condition where the gallbladder motility is seen as abnormal. Diagnostic imaging studies for biliary dyskinesia usually include a negative or inconclusive abdominal ultrasound or computed tomography followed by a hepatobiliary iminodiacetic acid (HIDA) scan. The HIDA scan is used to visualize the gallbladder and access its motility. The motility is reported in the form of an ejection fraction (EF). Billiary dyskinesia is diagnosed if the EF is less than 35%. However, there are many patients with an EF of greater than 35% but are exhibiting all the signs and symptoms for biliary dyskinesia. Aim: This study evaluated the efficacy of laparoscopic cholecystectomy as a treatment modality in symptomatic patients diagnosed with biliary dyskinesia with three distinct HIDA scan EF results. Materials and methods: They were a total of 654 verified case of laparoscopic Cholecystectomy done between January, 2013 and December 2016 at Westlake and West Suburban Hospital. A total of 163 cases out of the 654 had HIDA scan with calculated EF, therefore meeting the criteria to be included in this study. The patients pre and post-operative course was reviewed from their medical records and resolution of symptoms was determined by in phone interview. Results: A total of 29 (18%) patients were lost to follow up. Out of the 99 cases interviewed in the first group (EF <35%) 91 (92%) cases reported complete symptom resolution post cholecystectomy. Out of the 18 cases interviewed in the second group (EF between 35%-50%) 13 (72%) cases reported Lincey Alexida, Frederick M. Tiesenga. Laparoscopic cholecystectomy for biliary dyskinesia in patient with an extended spectrum of ejection fraction on hepatobiliary iminodiacetic acid scan. IAIM, 2017; 4(11): 14-17. Page 15 complete resolution post cholecystectomy. Out of the 17 cases interviewed in the last group (EF> 75%) 11 (65%) cases reported complete resolution of their symptoms Conclusion: Our study indicates that patient suffering with symptomatic biliary dyskinesia and has a HIDA with EF less than 50% or EF greater than 75% will most likely benefit from laparoscopic Cholecystectomy and could be a reasonable option to offer symptomatic patients.
Résumé
PURPOSE: The purpose of this study was to compare outcomes for surgical treatment with those for medical treatment of GB dyskinesia. METHODS: Retrospective analysis of medical records and telephone interviews of 67 patients diagnosed with GB dyskinesia was done at Pohang St. Mary's Hospital between January 2004 and December 2009. Group 1 (n=18) patients received laparoscopic cholecystectomy. Group 2 (n=49) patients received medical treatment. GB dyskinesia was the diagnosis if the patient had typical biliary colic symptoms without GB stones or other GI disease, and if the ejection fraction was less than 35% on Tc-99m-DISIDA scans. RESULTS: The average age of patients diagnosed with GB dyskinesia was 45.8 years old. The sex ratio was 15:52 (male:female). The average symptom duration was 25.4 days. All had RUQ and, or epigastric pain. There were no significant between group differences in age, sex ratio, symptom duration, symptoms, follow up period, and ejection fraction. In group 1, patient symptoms improved after treatment in 16 cases (88.9%); in group 2, patient symptoms improved in 19 cases (38.8%). Surgical treatment was significantly more effective than medical treatment. The reasons for choosing medical treatment were predominantly the preference of the doctors. CONCLUSION: Surgical treatment is a more effective treatment for GB dyskinesia than medical treatment. Therefore, laparoscopic cholecystectomy should be considered as the 1st line treatment of choice for GB dyskinesia.
