Conservative Management of Horizontal Root Fracture: A Case Report.

In cases where permanent teeth have closed apices and completely erupted roots, the probability of root fractures is increased due to the stable support given by the adjacent bone and periodontal tissues. Fractures have the potential to affect several dental structures, including the pulp, dentin, cementum, bone, and periodontal tissues. In cases of horizontal root fractures (HRF), the apical section typically maintains vitality; however, the present case presented an unusual apex necrosis.

Comparative study of the pure AH Plus sealer and its combination with triple antibiotic paste at different concentrations on bacteria.

Background: In this study, the effects of pure AH Plus sealer and its combination with triple antibiotic paste at different concentrations on bacteria have been investigated.

Materials And Methods: This study was accomplished by the means of a triple antibiotic paste combination (minocycline, metronidazole, and ciprofloxacin) at different concentrations (0%, 1%, 5%, 10%, and 25%) with AH Plus sealer on bacteria. Sealers were set in an incubator for 1 h, 1 day, 3 days, and 7 days, and then 10 µL of bacteria solution was placed on all samples except the negative control group.
