“…7,8 Many drugs have been tested over the years to reduce bacterial load, such as calcium hydroxide [Ca(OH) 2 ], one of the most widely used endodontic intracanal medications. 9,10 Ca(OH) 2 acts by direct contact, but its action against microorganisms that penetrate deep into dentinal tubules may be impaired. 11 Declaration of Interests: The authors certify that they have no commercial or associative interest that represents a conflict of interest in connection with the manuscript.…”

Calcium hydroxide associated with a new vehicle: Psidium cattleianum leaf extracts. Tissue response evaluation

et al. 2017

The aim of this study was to evaluate edemogenic activity and subcutaneous inflammatory reaction induced by Psidium cattleianum leaf extracts associated with Ca(OH) 2 . Thirty male Wistar rats, split equally into three groups [aqueous extract + Ca(OH) 2 ; ethanolic extract + Ca(OH) 2 ; and propylene glycol + Ca(OH) 2 ], were assessed every 3 h or 6 h (five animals in each period). Under general anesthesia, 0.2 mL of 1% Evans blue per 100 g of body weight was injected into the penile vein and each combination to be evaluated was subcutaneously injected into the dorsal region 30 min thereafter. Edemogenic activity was analyzed by spectrophotometry (λ=630 nm). For inflammatory reaction analysis, 50 rats received four polyethylene tubes (three experimental groups) and an empty tube (control group). The assessments were made at 7, 15, 30, 60, and 90 days, followed by hematoxylin-eosin staining and by the assignment of scores for evaluation of tissue response intensity. Ethanolic extract + Ca(OH) 2 yielded the largest edemogenic activity at 3 h. Intergroup differences at 6 h were not significant. The histological analysis showed progressive repair over time (p<0.05) and aqueous and ethanolic extracts produced similar responses to those of the control and Ca(OH) 2 + propylene glycol groups. Psidium cattleianum leaf extracts used as Ca(OH) 2 vehicles evoked similar tissue response when compared to Ca(OH) 2 associated with propylene glycol.

“…This tissue is initially loose connective, with collagen fibrils, blood vessels and reparative cells (fibroblasts and cementoblasts), which develops into a rather fibrotic and dense tissue which may later become partial mineralized. Complete apical closure with hard‐tissue formation would be the last step of this healing process, named biologic seal (Holland et al. 1979, Leonardo et al.…”

Calcium hydroxide barrier over the apical root‐end of a type III dens invaginatus after endodontic and surgical treatment

et al. 2006

View full text Add to dashboard Cite

Because of the variable morphology and extent of invagination, type III dens invaginatus represents a challenge for conventional treatment, often leading to the need for a surgical approach. Sealer 26 thickened with zinc oxide powder provided satisfactory clinical properties for use as a root-end filling material. Application of a calcium hydroxide barrier over the resected root-end is a potential treatment option to encourage tissue repair.
