The effects of different growth conditions on the susceptibility of five taxa to alkaline stress were investigated. Enterococcus faecalis ATCC 29212, Streptococcus sobrinus OMZ 176, Candida albicans ATCC 90028, Actinomyces naeslundii ATCC 12104, and Fusobacterium nucleatum ATCC 10953 were grown as planktonic cells, allowed to adhere to dentin for 24 hours, grown as monospecies or multispecies b...

Aim The aim of the present clinical study was to evaluate the endodontic method of treatment consisting of gentle preparation of the root canal and subsequent temporary filling with calcium hydroxide. The filling of the root canal with calcium hydroxide was repeated approximately at three-month intervals. Method The study consisted of a test group of 98 children with 103 non-vital single-root p...

BACKGROUND This study examined the effects of addition of 10% and 25% by weight calcium hydroxide on the physicochemical properties of Portland cement associated with 20% bismuth oxide in order to develop a new pulp capping material. MATERIAL AND METHODS The solubility, pH value, setting time, compressive strength, and push out bond strength of modified Portland were evaluated and compared to...

The aim of this study was to compare the analgesic effects of Calcium hydroxide and Chlorhexidine as intracanal medicaments in three different groups of patients. This interventional study was conducted over a period of one year at the Department of Operative Dentistry, Fatima Jinnah Dental Hospital, Karachi. 465 single rooted teeth of patients were divided into three equal groups with 155 teet...

Received: 17 December 2006 Accepted: 1 August 2007 Abstract: Objective: Bioactive glass is often used as a filler material for repair of dental bone defects. In different studies osteogenic potential of this material was proved, but its dentinogenesis property is in doubt. The purpose of this study was to evaluate the histological pulp responses of Calcium hydroxide and Bioactive glass placed d...

INTRODUCTION This study evaluated and compared colony forming units (CFUs) and minimum inhibitory concentrations (MICs) of calcium hydroxide and propolis as intracanal medicaments. MATERIALS AND METHODS Eighty human single-root and caries-free teeth were selected and divided into five groups. Crowns were removed. Root canals were then prepared in a step-back manner. The samples were then inoc...

Introduction: The ultimate goal of endodontic treatment is to eliminate the bacterial infection in the root canal system. While mechanical debridement combined with chemical irrigation removes the bulk of microorganisms, residual bacteria are readily detectable in approximately one-half of teeth just prior to obturation. Laser light can be used to destroy bacteria. This in vitro study was perfo...

Background and purpose: Calcium hydroxide and Chlorhexidine are among common intracanal medications. Recently an herbal composition named Carvacrol has been suggested as an intracanal medication. The purpose of this study was to compare antimicrobial effect of Carvacrol, Chlorhexidine and Calcium hydroxide on Enterococcus faecalis. Materials and methods: In this experimental study, 56 single...

Mineral trioxide aggregate (MTA) was developed in early 1990s and has been successfully used for root perforation repair, root end filling, and one-visit apexification. MTA is composed mainly of tricalcium silicate and dicalcium silicate. When MTA is hydrated, calcium silicate hydrate (CSH) and calcium hydroxide is formed. Formed calcium hydroxide interacts with the phosphate ion in body fluid ...
