The successful outcome of endodontic treatment depends on the reduction or
elimination of bacteria present in an endodontic infection. It has been reported that
chemo-mechanical instrumentation alone is not enough for this purpose.
The purpose of this in vitro study was to compare the pH changes that occurred
over a period of 14 days using four types of calcium hydroxide. Four types of calcium
hydroxide materials were filled in fifty extracted single rooted teeth which were kept
in individual vials containing distilled water at a pH of (7.4). Digital pH-meter was
used to measure the pH of different groups at two hours, 24 hours, 7 days & 14 days
after immersion of the specimens. The mean pH was found for all groups and
statistical analysis was carried out using ANOVA and POST HOC TEST (LSD).
Calcium hydroxide was found to significantly raise the root PH. Therefore calcium
hydroxide is an effective choice in clinical practice to be used as intra canal
medicament between appointments.
