BACKGROUND To evaluate the effects of intraalveolar placement of gel containing 0.2% chlorhexidine and 10gm of metronidazole on the incidence of alveolar osteitis. MATERIAL AND METHODS A total of 300 impacted third molars were extracted in 150 patients enrolled in this trial. In each subject a socket was randomly selected and packed to the crest of alveolar ridge with the gel. The contralater...

BACKGROUND to evaluate, in an initial way, the effectiveness of bioadhesive chlorhexidine gel 0.2% versus placebo as a preventive and therapeutic intervention of oral mucositis induced by radiation therapy and chemotherapy in patients diagnosed with head and neck cancer treated with chemoradiotherapy. MATERIAL AND METHODS In this pilot study, 7 patients (range of age: 18- 65), having histolog...

BACKGROUND Covering insertion sites with chlorhexidine impregnated dressings has been proven to be clinically effective in reducing catheter related blood stream infections (CR-BSI). Two chlorhexidine gluconate (CHG)-impregnated dressings are commercially available, a polyurethane foam disk and a film dressing containing a chlorhexidine gluconate-impregnated gel pad. While both have demonstrate...

The present study was conducted to determine the influence of 2 intracanal medicaments (calcium hydroxide, chlorhexidine gel 2%) when used either alone or combined on the short- and long-term sealing ability of permanent root canal fillings. Ninety human upper central incisors were divided into 4 experimental groups (n=20). All root canals were instrumented in a step-back motion and then treate...

removing the bacteria, including enterococcus faecalis, from the root canal is one of the important aims in endodontic treatment.we aimed to compare the antibacterial activity of chlorhexidine with two natural drugs. the antibacterial activities of three different propolis extracts (alcohol concentrations: 0, 15, 40%) and aloe vera gel on e. faecalis were compared using three methods: disk diff...

OBJECTIVE To compare the efficacy of three different herbal products (Tooth and Gums Tonic, Hiora-GA gel, and Spirogyl Gum paint) in reducing plaque, gingival inflammation and bacterial count in comparison with chlorhexidine M gel among participants with moderate to severe periodontitis. MATERIALS AND METHODS A total of eighty participants with moderate to severe periodontitis were initially ...

Chlorhexidine is a chlorinated phenolic disinfectant used commonly in mouthwash for its action against bacteria. However, a comparative study of the action of chlorhexidine on the cell morphology of gram-positive and gram-negative bacteria is lacking. In this study, the actions of chlorhexidine on the cell morphology were identified with the aids of electron microscopy. After exposure to chlorh...

Background: Over the years chlorhexidine has been used in the dental practice as an excellent antiplaque agent. Chlorhexidine not only exhibits special property of substantivity, it also possesses a broad antimicrobial spectrum which makes its use in wide variety of oral disorders. Virtually all disciplines of dentistry make use of this material in different formulations like mouth wash, gel, s...

BACKGROUND Peri-implant disease following successful integration of an endosseous implant is the result of an imbalance between bacterial load and host defense, which may affect not only the peri-implant mucosa but also involve the supporting bone. OBJECTIVES The aim of this study was to evaluate the adjunctive effect of a dental water jet rinse mixed with chlorhexidine gel to the nonsurgical...

The aims of this study were to compare the effectiveness of fluoride varnish and chlorhexidine gel in controlling white spot lesions (WSLs) adjacent to orthodontic brackets and to compare the ability of Quantitative Light-Induced Fluorescence (QLF) to measure mineral uptake with that of transverse microradiography (TMR). Thirty premolars with artificially induced WSLs were randomly assigned to ...
