Comparative Evaluation of Penetrative and Adaptive Properties of Unfilled and Filled Resin-Based Sealants When Placed using Conventional acid Etching, Lasing, and Fissurotomy Bur Technique of Enamel Preparation: An Scanning Electron Microscope Study.

Background: There is a confusion regarding selection of unfilled or filled sealant and method of enamel preparation before sealant application. This study was carried out to compare three techniques of enamel preparation using both unfilled and filled type of sealants.

Objective: The objective of the study is to assess the penetrative and adaptive ability of filled and unfilled sealants in three techniques of enamel fissure preparations.

An Microleakage Study for Comparative Analysis of Two Types of Resin-based Sealants Placed by Using Three Different Types of Techniques of Enamel Preparation.

Background: Clinicians always experience dilemmas while choosing the type of pit and fissure sealant and the method of enamel preparation before the application of sealant. This study was accomplished using the unfilled and filled types of resin sealant deploying three different techniques of enamel preparation.

Aim And Objective: To do a comparative analysis of unfilled and filled sealants by deploying three techniques of enamel preparation.

Adenomatoid odontogenic tumour: An enigma.

Adenomatoid odontogenic tumour (AOT) is an uncommon, hamartomatous, benign epitheial lesion of odontogenic origin. The current World Health Organisation (WHO) classification of odontogenic tumors defines AOT as being composed of the odontogenic epithelium in a variety of histoarchitectural patterns, embedded in mature connective tissue stroma, and characterized by slow, but progressive growth. The aim of this paper is to present three rare cases of intraosseous AOTs with varied clinical and radiographic features imposing the fact that AOT should be included in differential diagnosis of routine odontogenic cysts and tumours.

Comparative evaluation of antimicrobial activity of miswak, propolis, sodium hypochlorite and saline as root canal irrigants by microbial culturing and quantification in chronically exposed primary teeth.

Introduction: One of the essential factors for successful root canal therapy is elimination of bacterial contaminants using an effective root canal chemical irrigant such as sodium hypochlorite which inherently possesses certain disadvantages like irritation to periapical tissues, staining of the instruments, burning of surrounding tissues etc. The aim of the study was to explore newer irrigant agents which would probably be as effective or more and at the same time less irritating to the tissues than sodium hypochlorite. Our search included two such agents, propolis and miswak.
