Abstract

Background: The marginal seal is essential for sealant success because penetration of bacteria under the sealantmight allow caries onset or progression. The aim of the present study was to estimate and compare themicroleakage of pit and fissure sealant after various methods of occlusal surface preparation.Materials and methods: Thirty non-carious premolars extracted for orthodontic reasons were equally divided intothree groups. In group one, occlusal fissures were opened with round carbide bur, in group two, occlusal surfaces ofthe teeth were cleaned with a dry pointed bristle brush and samples of group three were cleaned with a slurry of fineflour of pumice in water using rubber cup. Then fissures of all teeth were etched using 35% phosphoric acid gel priorto placement of Conseal F (SDI) light cured sealant, the teeth were thermocycled, then they were immersed in 1%methylene blue for 24hours. Each tooth was sectioned bucco-lingually to detect the microleakage.Results: Different levels of microleakage were observed among various groups, highest level was recorded forbrushing group followed by pumice group, while round bur samples showed the least microleakage whencompared with other groups. Statistically the difference was not significant between brushing and pumice groups,while it was significant between round bur and other groupsConclusion: Preparation of occlusal surface with round bur was very effective in reduction of microleakage incomparison with the traditional pumice slurry and bristle brush.

Abstract

Anal fissure is a most common cause of anal pain [1].This prospective study includes 236 patients complaining of anal fissure treated from a period of September 2013 to December 2015 to assess options of management of anal fissure. Male patients were 121 (51%) and female were 115 (49%). All patients were clinically assessed in an outpatient clinic and conservative treatment started to all patients that shown to be effective in 141 patient (60%). Surgical treatment applied to 95 patients (40%)whom not responded to conservative treatment, or, patients with recurrent fissure. Lateral sphenectrotomy was the surgical procedure applied in open or close method (62 and 33 patients respectively), under local or general anesthesia (54 and 41 respectively). Local anesthesia was associated with a significant low duration of admission from 1 to 24 hours (mean of 3 hours) while general anesthesia with a significant higher duration of 12 to 36 hours (mean of 19 hours). The healing rate following surgery in a local or general anesthetic approach was 95%. No difference in a healing rate between open or closed technique of sphenectrotomy. Flatus incontinence was reported in 3 patients. Initial treatment of anal fissure should be conservative, lateral sphenectrotomy is a safe procedure with a high cure rate, low incidence of complications and could be performed under local or general anesthesia.
