STATEMENT OF PROBLEM Pit and fissure sealant therapy has been approved as an effective measure in the prevention of occlusal dental caries. Resin based materials are the most common materials used worldwide. A variety of resin based fissure sealants are produced and used. Most of them have been presented with ideal results in research environment. However, their effectiveness in the real life, ...

recently, self-etching fissure sealants have been introduced to reduce technical sensitivity; however, their efficacy should be assessed. the aim of this study was to assess of the microshear bond strength of self-etching and conventional fissure sealants.thirty non-carious third molars were randomly divided into three groups (n=10). microcylinders of concise fissure sealant were bonded to prep...

This paper proposes an automatic lung lobe segmentation method in a supervised way. The lung image is given as input and the lung image is segmented using iterative threshold method. Then fissure information is enhanced using log supportive filter. Then Fissure locations are extracted using Vector training and matching process. Finally the lung lobes are segmented and marked as individual lobes...

Pulmonary fissures separate human lungs into five distinct regions called lobes. Detection of fissure is essential for localization of the lobar distribution of lung diseases, surgical planning and follow-up. Treatment planning also requires calculation of the lobe volume. This volume estimation mandates accurate segmentation of the fissures. Presence of other structures (like vessels) near the...

2014 Anal fissure is a common painful anorectal condition which affects people of various age groups, and deteriorates their quality of life. Chronic anal fissure requires medical intervention either by pharmacotherapy or by surgery. Various pharmacological agents have been used in the treatment of chronic anal fissure with the aim of relaxation of internal anal-sphincter smooth muscle. Diltiaz...

Background: Although lateral internal sphincterotomy is an effective treatment of chronic fissure in ano, it’s of potential to better-done and lower complications. And the aim of this prospective randomized trial was to compare the effectiveness and morbidity of open and closed sphincterotomy in the treatment of chronic anal fissure. Methods: The two methods were compared in a randomized contro...

The objective of this paper is to develop a segmentation system in order to assist the surgeons to remove the portion of lung for the treatment of certain illness such as lung cancer, and tumours. The fissures of lung lobes are not seen by naked eyes in low dose CT image, there is a proposal for automatic segmentation system. The lung lobes and nodules in CT image are segmented using two stage ...

INTRODUCTION Health-related quality of life (HRQL) is a significant factor in describing the burden of illness and the impact of treatment in patients with gastrointestinal disease. Type D (distressed) personality is defined as the co-occurrence of negative affect and social inhibition. AIM To assess the prevalence of type D personality in patients with anal fissure and to investigate whether...

OBJECTIVE The aim of this study was to investigate the mechanical properties (flexural strength, micro-shear bond strength) and remineralizing potential of fissure sealants by adding various concentrations of β-tricalcium phosphate nanoparticles. MATERIALS AND METHODS This in-vitro study consisted of five experimental groups containing prepared nano-fisssure sealants (1-5 wt.% β-TCP nanoparti...
