Objective: To study the effect of the sharp marginal ridge of the abutment on the casting of the fit metal full crown in dental preparation.Methods: We established the models of the designed crown-based-teeth(American Dental Association style,No2 trail) with a sharp or smooth marginal ridge,and cast a metal crown for each model.We injected silicone into the crown and immediately fixed it onto each model.Then we took out the solidified silicone and measured its thickness between the crown and the occlusal face of each model.The thinner the thickness,the better the fitness.Results: The average silicone thickness was 250 ?m in the smooth marginal ridge group and 1 660 ?m in the sharp marginal ridge group,with significant difference in between(P

Objective: Ear, nose and throat foreign bodies are common in ENT clinical practice. This study was designed to establish the local data of otorhinolaryngeal foreign bodies in term of prevalence among paediatric and adult groups, the clinical features, types of foreign body at different sites, and laterality of foreign bodies. Method: This study was carried out at ENT department, Sarawak General Hospital, Malaysia, from 1st January 2005 to 31st December 2009. A total of 1084 cases were included and statistically analyzed. Result: Ear foreign bodies showed the highest incidence which was consisted of 480 (44.3%) cases, followed by nose in 270 (24.9%) cases, pharynx in 251(23.2%) cases, esophagus in 57 (5.3%) cases and laryngo-tracheobronchial tree in 26 (2.4%) cases. Otorhinolaryngeal foreign bodies occurred more frequently in 0-10 year old age group which constituted 651 (60.1%) cases. The descending order of frequency for foreign body sites in adult was pharynx (17.2%), ear (12.8%), esophagus (3.1%), nose (1.7%) and laryngo-tracheobronchial tree (1.1%). The type of foreign bodies varies with age group and site of foreign body lodgement. In general, common foreign bodies in both adult and children were food related, with the additional of small objects such as plastic toy in paediatric group. Conclusion: Otorhinolaryngeal foreign bodies were found more frequently in children. The types of foreign body were different from age group and sites of foreign body lodgement. The local food constituted the highest incidence of ear, nose, and throat foreign bodies with additional of plastic toys in paediatric group.

BACKGROUND:There is little evidence on the use of al ogeneic tendon graft in the reconstruction of ankle joint.
OBJECTIVE:To explore the clinical outcome of anatomical reconstruction of the lateral ligaments with cryopreserved al ogeneic tendon graft in patients with chronic ankle instability.
METHODS:Twenty-six patients with chronic lateral instability underwent anatomical reconstruction of the lateral ligaments with cryopreserved al ogeneic tendon. There were 18 cases of simultaneous injury or chalasia in calcaneofibular ligament and anterior talofibular ligament, and 8 cases of anterior talofibular ligament injury or chalasia. The ankle joint function was evaluated according to AOFAS scale and Good classification. The affect ankle and healthy ankle were compared in the extension, plantar flexion activity, and metaleg activity.
RESULTS AND CONCLUSION:Al the 26 patients were fol owed up for 9-24 months with a mean of 15 months. No cases appeared recurrent ankle lateral instability. The mean AOFAS score in the group of calcaneofibular ligament and anterior talofibular ligament was improved from (48.4±3.7) points preoperatively to (88.2±3.8) postoperatively, while that in the group of anterior talofibular ligament was improved from (50.0±6.4) points preoperatively to (89.5±3.4) points postoperatively. According to Good score, there were excellent in 19 feet, good in 6 feet, fair in 1 foot, with an excellent and good rate up to 96%. No serious complication was occurred in this group. Anatomical reconstruction of the lateral ligaments with cryopreserved al ogeneic tendon graft can increase the tendon-bone contact area, improve the rate of tendon healing, and enhance the stability of ankle joint in patients with chronic ankle instability. Further studies are needed to verify its long-term efficacy.
