RESUMO
OBJECTIVES: The present evaluate the feasibility of Computed tomography (Dentascan), in assessment of the implant site in posterior maxilla & mandible. MATERIAL AND METHODS: data of total 11 patients with 20 implant sites were involved in the present study. Out of the 20 implant sites selected 10 were in posterior maxilla and 10 in posterior mandible. All the patients were routinely examined by panoramic radiography and CT. All images obtained i.e., conventional panoramic radiograph, and film based Dentascan MPR- CT images were evaluated for the detectability of mandibular canal at the mental foramen, 1 cm, 2 cm, and 3 cm posterior to mental foramen. The judgments were then compared by using the four point grading score. RESULTS: Both the statistical analysis and radiographic observation showed that Dentascan MPR CT gives significantly clearer images at the mental foramen and 1 cm, 2 cm , 3 cm posterior to it. Dentascan also provides significantly better visualization of the vital structures along with the bone density. The panoramic and Dentascan MPR CT images did not show a significant difference in visualization of the crest of alveolar ridge in both maxillary as well as the mandibular arch. CONCLUSION: The Dentascan MPR- CT images revealed significantly clearer images as well as better visualization of the vital structures than conventional panoramic radiography. Apart from providing clearer images Dentascan also gives the buccopalatal/buccolingual dimension at the implant site, along with the density of the available bone.
RESUMO
PURPOSE: To evaluate the versatility of the collagen membrane as both drug carrier and biologic dressing material to cover the raw wounds created after the surgical excision of fibrotic bands in oral submucous fibrosis. MATERIALS AND METHODS: The study comprises of ten patients. The patients of age group 20 to 50 years were selected. The collagen is reconstituted by injecting with dexamethasone and placentrix solution leaving a small overlap on to the remaining mucous membrane and the graft is sutured. Preoperative and post operative assessment was done regarding the improvement in mouth opening, decrease in burning sensation, change in colour of oral mucosa and clinically grading the extent of lesion. RESULTS: The results were found appreciable in seven patients while in the remaining three patients it showed relapse because of inadequate physiotherapy. All the ten patients were comfortable with intra oral collagen grafting. The collagen remained moist and supple intraorally, and remained in close contact with the underlying tissues, providing a strong mechanical barrier. The material was effective in attaining haemostasis, relieving pain and preventing extensive contracture. CONCLUSION: In this study of short duration, the nature of collagen membrane was observed as both biological dressing material and drug carrier. It was found as a very suitable alternative to the other graft material mentioned for the repair of defects in the mucous membrane created by surgical excision of fibrous bands in oral submucous fibrosis.
RESUMO
Basel cell adenoma is a benign epithelial salivary gland tumor that appears to have unique histologic characteristics. The diagnosis of this entity must be established by histological study. It commonly occurs in parotid gland and very rarely in submandibular gland. Here we report a case of basel cell adenoma of submandibular gland.
RESUMO
OBJECTIVE: The objectives of this study was to evaluate subjectively the analgesic efficacy of Oral Diclofenac Sodium against Diclofenac Sodium Transdermal patch in the management of postoperative pain following surgical removal of impacted mandibular third molars. MATERIALS AND METHODS: Twenty healthy subjects belonging to both the sexes in the age group of 18-40 years with bilateral mesioangular impactions of mandibular third molar teeth underwent surgical removal under local anaesthesia by administering an inferior alveolar nerve block on two different occasions with a minimum interval of 1 week in-between the procedures. The postoperative pain was recorded on visual analog scale, a verbal rating scale, a pain relief scale and a pain intensity scale. Readings were taken at 2 hours, 4 hours, 8 hours, 12 hours and 24 hours postoperatively, taking the time at which the surgery was completed as a reference. On the second and third days, the repeat medication was administered at that reference time and recordings taken at the same intervals for a total of 3 days. Patients received the study medication i.e. Diclofenac Sodium 100mg once a day for 3 days after performing surgery on one side and the same patients were given Diclofenac Sodium Transdermal Patch 100mg once a day for 3 days after performing surgery on the contralateral side. RESULTS AND OBSERVATIONS: Both the statistical analysis and clinical observation showed that on the first postoperative day diclofenac sodium administered orally has slightly more significant efficacy when compared to the drug administered transdermally. However, on the second and third postoperative days there was no statistical or clinical difference in the pain control by either route of administration. CONCLUSIONS: The study concludes that transdermal diclofenac sodium can be used as an alternative form of pain control following removal of impacted mandibular third molars, however considering that the analgesic potency might be lesser in the immediate postoperative period, it might be prudent to use oral diclofenac sodium for immediate postoperative pain relief, following which transdermal route can be used for pain control.
RESUMO
Massive sequestration of the upper jaw has been reported only rarely in the literature. A case is presented of a 65-year-old diabetic male with massive sequestration of the maxilla. The relevant literature is reviewed.
