Eksperimentel: Calcium Silicate Intracanal Medication
Calcium silicate-based bioceramic Intracanal Medication as Bio C-Temp (Angelus)
|
Calcium silicate-based bioceramic materials have gained attention for their bioactivity and biocompatibility, acting through hydration with calcium hydroxide release followed by hydroxyapatite formation that promotes healing.
Bio-C Temp is an example, characterized by high calcium ion release, alkaline pH, adequate radiopacity, and good biocompatibility.

Eksperimentel: Calcium Hydroxide Slurry mixed with Sodium Hypochlorite
Calcium Hydroxide slurry mixed with 3% Sodium Hypochlorite
|
Combining calcium hydroxide with sodium hypochlorite (NaOCl) has been proposed.
NaOCl provides rapid and potent antimicrobial and tissue-dissolving effects, while Ca(OH)₂ offers prolonged action.
Both agents retain their properties when combined, and this combination may produce a synergistic effect that enhances disinfection and reduces chair time in two-visit treatment protocols.

Aktiv komparator: Calcium Hydroxide
Calcium Hydroxide Intracanal Medication (Control Group)
|
Calcium hydroxide ICM being the most widely used due to its high alkalinity, antimicrobial properties, endotoxin neutralization, and ability to reduce periapical inflammation.
It is applied as an aqueous mixture or polyethylene glycol-based paste and provides a slow but sustained antimicrobial effect.
Despite their benefits, Ca(OH)₂ medicaments re limited by their solubility, susceptibility to tissue fluids, potential to weaken tooth structure over time, and reduced effectiveness against resistant microorganisms such as Candida Albicans and Enterococcus Faecalis.
