Evaluation of pH and calcium ion diffusion from calcium hydroxide pastes and MTA.
Acta Odontol Latinoam
April 2017
The aim of this ex vivo study was to evaluate changes in pH and calcium ion diffusion through root dentin from calcium hydroxide (Ca (OH) ) and mineral trioxide aggregate (MTA) pastes at 7, 30 and 60 days; and the relationship between pH and ion diffusion. Thirty-two human premolars were used. Crowns were sectioned and root canals instrumented and filled in with the following preparations: 1) Ca(OH) + distilled water (n=7); 2) Ca(OH) + 0.

The aim of this study was to analyze the in vitro behavior of the pH of different irrigating solutions, used alone or consecutively, after contact with extracted human teeth. Mandibular human premolars were selected. The middle thirds were divided into 6 parts.

- Calcium hydroxide (Calpha(OH)2) paste has been used historically as a root canal dressing to aid in the healing of dental tissues.
- A study was conducted using 21 extracted teeth to assess the dissolving effectiveness of calcium hydroxide paste mixed with different vehicles by examining the uninstrumented canal walls under a scanning electron microscope (SEM).
- Results indicated that pastes mixed with saline, chlorhexidine, and propylene glycol showed significantly better cleaning of canal walls, while other mixtures left more organic material behind.
