This study assessed the pulp healing response to human freeze-dried bone (FDB) in two cynomolgus monkeys using 36 noncarious primary teeth pulpotomized and randomly assigned to three medicaments. FDB was applied on the pulp stumps and covered with sterile tin foil as experimental group. The two other groups received either calcium hydroxide [Ca(OH)2], or IRM (reinforced ZOE). All teeth were res...

INTRODUCTION Root canal treatment involves the elimination of intraradicular microorganisms. Calcium hydroxide [Ca(OH)(2)] is the most widely used canal dressing material. Enterococcus faecalis (E. faecalis) has been reported to be resistant to Ca(OH)(2) in-vivo. The purpose of this study was to evaluate the efficacy of Ca(OH)(2) on the elimination of intraluminal and intratubular E. faecalis. ...

AIM This study compared the amount of aqueous-based and oil-based calcium hydroxide remaining in the canal, after removal with two different chelators 17% EDTA, 20% Citric acid and 0.2% Chitosan in combination with ultrasonic agitation. METHODS AND MATERIAL Cleaning and shaping of root canals of 28 mandibular premolar was done and canals were filled either with Metapex or Ca(OH)2 mixed with d...

In this study, we investigated the prevention of enzymatic urea hydrolysis in fresh urine by increasing the pH with calcium hydroxide (Ca(OH)2) powder. The amount of Ca(OH)2 dissolving in fresh urine depends significantly on the composition of the urine. The different urine compositions used in our simulations showed that between 4.3 and 5.8 g Ca(OH)2 dissolved in 1 L of urine at 25 °C. At this...

Effects of carbonation temperature and compacting pressure on basic properties of calcite block were studied using Ca(OH)2 compact made with 0.2-2.0 MPa and their carbonation at 200-800ºC for 1 h. Microporous calcite was obtained only when carbonated at 600ºC using Ca(OH)2 compact made with 0.2 MPa even though thermogravimetry analysis showed that calcite powder was stable up to 920ºC under CO2...

In this work at the first step calcium hydroxide nano-particles were synthesized via sono-chemical method at room temperature. At the second step aminated multi-walled carbon nano-tubes was prepared via chemical modification of surfaces of CNT. Finally modified-MWCNT and Ca(OH)2 were added to paraloid matrix by aid of ultrasonic irradiation. Paraloid-modified-MWCNT-Ca(OH)2...

Statement of the Problem A great challenge in periodontal therapy is the regeneration enhancement of osseous defects through applying osteoinductive materials. Demineralized freeze-dried bone allograft (DFDBA) has already been introduced as an allograft with osteoconductive and variable osteoinductive properties. Calcium hydroxide [Ca(OH)2] is an available well-known material in dentistry, whic...

The purpose of this study was to determine the effect giving ratio Calcium Hydroxide (Ca(OH)2) and Magnesium Sulfate (MgSO4) with different doses on growth white shrimp (Litopenaeus vannamei) production in freshwater media. This research conducted by experimental method using Completely Randomized Design (CRD). parameter studied how addition Ca(OH)2 Sulfat lime maintenance container 5 treatment...

Carbonic anhydrase II (CA II) expression is vital to normal osteoclast function. We and others have previously reported induction of CA II messenger RNA (mRNA) expression by 1,25(OH)2D3 in myelomonocytic cells and marrow culture. However, since 1,25(OH)2D3 stimulates osteoclast differentiation as well, we wished to separate direct effects of 1,25(OH)2D3 on the CA II gene from the differentiatin...

Direct pulp capping is the most conservative restorative procedure for protecting the pulp from further insult, permitting healing and repair. Calcium hydroxide Ca(OH) 2 is the most commonly used materials for direct pulp capping . The aim of this study was to compare clinically and radio graphically Ca(OH) 2 with Resin modified glass ionomer (RM-GIC) as a direct pulp capping material. Forty si...
