The aim of this study is to determine the effect of the laser diode with a wavelength of 940 nm in endodontic treatment, by irradiating channels in several stages of treatment, combined with standard lavage solutions. The study determines the removal of the smear layer and the permeability of the dentinal tubules as seen in scanning electron microscopy. Material and method. The study was conducted on 16 mono-radicular extracted teeth having an orthodontic purpose or which presented periodontal lesions and a 3-4 degree of mobility. The teeth were subjected to an endodontic protocol and a laser protocol, followed by a SEM analysis. Results. Increasing the number of cycles has as result the removal of smear layer and of the debris layer by the opening of the dentinal tubules. Conclusions. 940 nm diode laser can be safely and effectively used in endodontic treatments, without harmful effects on periodontal tissues. Using 940 nm laser diode in endodontic treatment has a synergistic effect which has been achieved with standard lavage.
The purpose of the study is to evaluate, according to the visual analog scale, the incidence of pain that occurs after the endodontic treatment of teeth with chronic asymptomatic apical periodontitis using different irrigation protocols. Material and method. The study was carried out on a sample of 120 patients aged 20-65 years, of which 65 females and 55 males. Pain evaluation was performed by using the visual analogue scale of pain by 4 levels (no pain, mild, moderate and acute) and was carried out at 4, 24 and 48 hours after the termination of the surgical intervention. Results. The statistical analysis of the post-operative pain (0h, 48h) in the case of the four groups using the chisquare-test showed the presence of significant differences (p<0.05). The calculation of the analyzed average postoperative pain batch shows values of 23.3%, of which severe pain represents only a percentage of 3.6%. The study of the correlation between pain intensity and distribution by sex and age groups showed significant differences. Conclusions. After treatment, pain occurs in the first 24 hours, and then gradually decreases to 48 hours. This is a clear indication that one should not intervene immediately to relieve pain through the extraction of the tooth or by initiating a re-treatment session.
Introduction. Patients increased aesthetic requirements have determined the use of composite resins for the restoration of posterior proximal lesions. But one of their defects is the high polymerization shrinkage. Admira Fusion is the first “nano-ORMOCER” made by Nano-hybrid technology and ORMOCER (ORganic MOdified CERamic) which have a 50% lower polymerization shrinkage compared to conventional composite materials, also lower contraction stress, high surface hardness and marginal resistance. Futurabond U is a universal adhesive which associated with Admira Fusion accomplishes a restoration with aesthetic and functional performances. Case presentation. The patient presented for aesthetic restoration of tooth 45 which showed no painful pathology. For the restoration, Admira Fusion (Voco) and Futurabond U (Voco) were chosen and applied according to minimally invasive direct adhesive technique and for compaction, Compothixo instrument was used. Conclusions. The material and the work method have led to the achievement of a restoration that satisfies the aesthetic and functional principles.
Since there are not many references in literature about the action of diode laser 940nm on the dentin and root smear layer, the aim of this study is to evaluate and compare, through SEM analysis, the efficiency of the Sodium hypochlorite 2% (CERKAMED) - EDTA 17% (CERKAMED) combination, operated in the middle and apical third of the root, by conventional syringe needle EndoEze and diode laser 940nm treatment. The study was performed on 40 single-root teeth, which were divided into two groups: group A consisting of 20 teeth, for which irrigation was performed only with the syringe and a top open side needle EndoEze Irrigator, resulting in a turbulence moving upward which efficiently irrigates the root canal and prevents periapical water solution; and group B consisting of 20 teeth, which benefited from irrigation associated with diode laser 940nm treatment. In the middle third and apical third smear layer removal was more effectively achieved when teeth benefited from irrigation associated with the laser diode treatment. In Endodontics, Diode laser is a good decontamination system, with biostimulation effect, which is important in healing the periapicale area. Significantly better results were obtained using 940nm laser diode associated with successive irrigation with 2% NaOCl and 17% EDTA, as compared to the conventional technique performed by syringe and lavage needle EndoEze Irrigator (Ultradent).
