The purpose of this review is to present the potential for incorporation ozone therapy into practice dentistry.Ozone gas has a high oxidation and 1.5 times greater than chloride when used as an antimicrobial agent against bacteria, viruses, fungi, protozoa. It also capacity stimulate blood circulation immune response. Such features justify current interest in its application medicine dentistry have been indicated treatment 260 different pathologies. can be alveolitis replacement antibiotic...

Photodynamic therapy (PDT) is a new technique introduced in endodontics that combines the action of photosensitizer (dye) and low intensity light source. Currently, there are no PDT studies evaluating microbial disinfection root canals order to compare effects delivery systems activation. The aim this study was evaluate effectiveness reducing Enterococcus faecalis, with without aid an intracanal optical fiber.Extracted single-rooted teeth were selected, instrumented, inoculated E. faecalis...

The disadvantage of photodynamic therapy (PDT) is in the photosensitizing agents that may stain tooth structure. There no register PDT studies evaluating protocols to minimize concern. present study evaluated efficiency chemical adjuncts methylene blue dye (MB) removal after PDT.Forty single-rooted teeth, root canal preparation, were filled with 0.01% MB for 5 min, and irradiated diode laser 660 nm at 40 mW 240 sec (total energy 9.6 J). specimens divided into four groups (n = 10), according...

OBJECTIVE: New drugs have to be assessed in endodontic therapy due the presence of microorganisms resistant therapeutic procedures. Thus, this study evaluated time- and concentration-dependent cytotoxicity different antibiotics used therapy. MATERIAL AND METHODS: Human gingival fibroblasts were treated divided into following experimental groups: Group I - control; II ciprofoxacin hydrochloride; III clyndamicin IV metronidazole. Each drug was at concentrations 5, 50, 150, 300 mg/L for 24, 48,...

Apicoectomy failure is generally related to inappropriate marginal sealing of the retrocavity, which allows percolation microorganisms and their products from root canal system periapex. This study evaluated tubular penetration sealers permeability after retrocavity irradiation with Er;Cr:YSGG laser retrofilling MTA or cyanoacrylate. Twenty-two single-rooted teeth were decoronated endodontically treated, apical 3 mm resected ends retroprepared a low-speed bur. Twenty roots randomly assigned...

Low-intensity laser therapy (LILT) is widely used for wound healing promotion and its mechanism of action may be due to an enhancement blood supply. The aim this study was evaluate flow alterations in a model, using Doppler flowmetry (LDF) associated with normalized perfusion parameter.An injury provoked 15 rats measured periodically over period 21 days. Control groups were established LDF He-Ne effects on microcirculation. A 1 J/cm(2) dose utilized, 6 mW/cm(2) irradiance.The results...

Summary SEM analysis of endodontic instruments from a Ni–Ti rotary system was assessed, before and after using them, considering their defects deformations. Twenty Twisted File®, BioRąCe®, Mtwo®, EndoWave® were micrographed at 190× magnification. The files washed again to view alterations as the presence or absence irregular edges, grooves, microcavities, scraping. Simulated root canal preparations performed these instruments. cleaned received microscopic being used five times. After tests...

Objectives This study evaluated the antimicrobial efficacy of ozone therapy in teeth contaminated with Pseudomonas aeruginosa, Enterococcus faecalis, and Staphylococcus aureus using a mono-species biofilm model. Parallel to this, aimed evaluate cytotoxicity for human gingival fibroblasts. Material Methods: One hundred eighty single-root were aureus. Groups formed: Group I – control; II standard protocol; III protocol + gas at 40 µg/mL; IV aqueous 8 µg/mL. In parallel, fibroblasts submitted...

Failure of apicectomies is generally attributed to dentine surface permeability as well the lack an adequate marginal sealing retrofilling material, which allows percolation microorganisms and their products from root canal system periodontal region, thus compromising periapical healing. The purpose this study was evaluate after apicectomy treatment with 9.6 µm TEA CO2 or Er:YAG 2.94 laser irradiation. Sixty-five single rooted human endodontically treated teeth were divided into five...

Herpes simplex virus (HSV) is one of the most common viral infections human being. Although seropositive persons do not manifest symptoms, infected individuals may present recurrent infections, characterized by cold sores. HSV-1 infection can result in potentially harmful complications some patients, especially those with compromised immunity. We report a clinical case patient severe oral lower lip. The treatment lesions association high-intensity (erbium-doped yttrium aluminum garnet, 2.94...

During endodontic therapy, cleaning of root canals is performed using files and auxiliary chemical substances, it important that the endodontist be familiar with instruments used in daily practice. This study evaluated, under scanning electron microscopy (SEM), quality surface finishing unused rotary instruments. Fifty sizes 20, 25 30 from different commercial brands (ProFile, Protaper, Race, Hero K3 Endo) were removed directly their packages had final 3 mm examined a microscope at x190...

Root perforation is a common endodontic accident. Its management depends mainly on root canal disinfection and sealing the area by preventing any communication with periodontium to prevent recontamination. A patient was referred treat due previous treatment of tooth #22. The diagnosis symptomatic periapical periodontitis, plan retreat #22 make surgical intervention (apicoectomy) associated antimicrobial photodynamic therapy as complementary technique. Five mineral oxides (5MO) cement used...

One problem in cases of healing-resistant periapical lesions is to eradicate the contamination at area. This due microbiological biofilm formed by microorganisms and their subproducts lodged apical third root, on both cementum dentin surface. Paraendodontic surgery consists mechanical removal harmful agents promote healing health. The purpose this study was assess results Er:YAG laser irradiation root newly extracted teeth eliminate microbial apex Apical performed with an device using...

In some situations, endodontic infections do not respond to therapeutic protocol. these cases, it is suggested the administration of an alternative intracanal medication that presents a wide spectrum action and has in-depth effect on root canal system. The purpose this study was assess antimicrobial ciprofloxacin, metronidazole polyethylene glycol natrosol vehicles with different associations concentrations. minimum inhibitory concentration (MIC) determined by using agar dilution method....

Abstract – Background aim: The aim of this study was to evaluate, by radiographic and histomorphometric analyses, the effects high‐power diode laser irradiation on root surfaces delayed replanted rat teeth. Material methods: Maxillary right incisors were extracted from 60 Wistar rats kept dry for min. Subsequently, canals prepared filled with calcium hydroxide paste. According surface treatment before replantation, teeth assigned four groups ( n = 15): G1 (negative control) no treatment; G2...

Apical sealing is essential for the success of paraendodontic surgery, so any procedure that may favor an adequate apical remainder should be performed. The purpose this study was to evaluate influence diode laser irradiation on root-end cavities with MTA retrofillings. Root canals in twenty extracted human teeth were shaped K-files and filled gutta-percha. apexes cut off preparations roots divided randomly 2 groups. Group 1 (ten specimens) retrofilled MTA. irradiated laser, W 20 seconds,...

Microbial infection plays an important role in the development of pulp necrosis and formation periapical lesions. In vitro vivo research this field, traditionally microbiological culture methods using paper point sampling quantitative culture, faces difficulties completely removing bacteria from root canal system analyzing sequential procedures. This study employed genetically engineered bioluminescent a light-sensitive imaging to allow real-time visualization infection. Ten extracted teeth...
