This study compared the antimicrobial effectiveness of nine dental materials and a negative control agent against 21 strains or species of bacteria using an agar diffusion assay. The materials were: 1. Camphorated parachlorophenol mixed with calcium hydroxide (CPC + Ca(OH)2). 2. CPC mixed with zinc oxide (CPC + ZnO). 3. Formocresol mixed with zinc oxide and eugenol (FC + ZOE). 4. Chlorhexidine ...

Dry socket is often treated in dentistry with intra-alveolar dressings; the use of them remains controversial and has been related to some side effects such as neuritis, foreign body reactions, and myospherulosis. We present a case of an intra-alveolar dressing (zinc-oxide eugenol paste) that mimicked a trigeminal neuralgia for 3 years and caused a right maxillary chronic osteomyelitis and fore...

Pulpal respiration in second and third premolar dog teeth was measured by a radioisotope tracer determination. Dental amalgam, a zinc oxide and eugenol base, and a calcium hydroxide base were placed into a cavity preparation. Following a two-week period the teeth wer~ extracted intact. The pulp tissue was removed and suspended in a phosphate buffer saline solution (PBS) which 14C-succinic acid ...

INTRODUCTION Pulpectomy of primary teeth is mostly carried out with hand files and broaches which is tricky and time consuming procedure. The development of new design features like varying tapers, non-cutting safety tips and varying length of cutting blades have resulted in new generation of rotary instruments. AIM To compare and evaluate cleaning efficacy, canal preparation and volumetric f...

The primary tooth pulpectomy is a common clinical procedure. The choice of filling material is important to the success rate, but antibacterial properties of such materials against organisms known to inhabit infected primary root canals have not been well documented. This study compared the antibacterial effectiveness of 10 materials: 1. Calcium hydroxide mixed with camphorated parachlorophenol...

The aim of this study was to evaluate the response of rat subcutaneous tissue to MTA Fillapex® (Angelus), an experimental root canal filling material based on Portland cement and propylene glycol (PCPG), and a zinc oxide, eugenol and iodoform (ZOEI) paste. These materials were placed in polyethylene tubes and implanted into the dorsal connective tissue of Wistar rats for 7 and 15 days. The spec...

Aim: To evaluate and compare the instrumentation time, obturation quality of obturation, clinical radiological success pulpectomized teethfollowing root canal preparation primary molars with rotary manual file system. Methods: A total 150 requiring pulpectomy were selected from children aged four to seven years. These teeth divided into three groups 50 each. In Groups 1, 2, 3, cleaning shaping ...

Introduction: Airtight sealing of the root canal is foremost desirable result any treatment, but getting perfect filling always problematic, which could be due to multiple reasons. One such majorly reason impacting obturation sealer utilized. Objective: The present study was done for evaluating microleakage in zinc oxide eugenol cement (ZOE) and epoxy resin-based (AH Plus) sealers using linear ...

AIM The purpose of this in vitro study was to assess and compare the retention of zirconia copings luted with different luting agents onto zirconia and titanium abutments. MATERIALS AND METHODS Titanium and zirconia abutments were torqued at 35 N/cm onto implant analogs. The samples were divided into two groups: Group A consisted of four titanium abutments and 32 zirconia copings and Group B ...
