This review compiles information from Medline, PubMed, ScienceDirect, Google Scholar, SciELO databases. Its objective is to provide biosecurity recommendations, highlighting the use of informed consent in dental practice in the context of the COVID-19 pandemic, according to current Peruvian regulations. A systematic review of articles, manuals, interviews, editorials, web pages, grey literature included, evidence discredited and information endorsed with articles published in indexed journals, relating ethical and deontological aspects of dental practice in biosafety criteria. In conclusion, the use of informed consent is important because there is a high risk of cross-infection as the reinforcement of several aspects of biosafety like the appropriate use of personal protective equipment (PPE), for the benefit of patients and staff.

Objetive: To determine the photodynamic effect of methylene blue (MB) and toluidine blue (TBO) activated with therapeutic laser on Streptococcus mutans and Candida albicans biofilms. Material and methods: Sixty-one biofilm samples were analyzed in brain heart culture media (BHI) for 6 days, the samples were divided into 4 groups and immersed in: experimental group in 0.01% MB and 0.05% TBO, positive control group in 0.12% chlorhexidine gluconate (CHX) and negative control group in 0.9% sodium chloride (NaCl). The MB and TBO samples were irradiated with therapeutic laser with a wavelength of 660 nm, and 9 J/cm2 of power, each enamel block was in post-irradiation culture. The samples were cultured separately for the S. mutans and C. albicans strains, the method used was that of serial dilutions for the quantification of CFU after 5 days of culture. For the analysis, Student's T and Anov...

The C-shaped root canal system is an anatomical variation usually found in second mandibular molar with fused roots, present a transverse morphology that describes an arc of 180º or more, with a single taped hole orifice. The present clinical case describes the endodontic treatment with last generation equipments of a mandibular molar with C- shaped type IV and fork at apical level in a male patient that has pain to percussion, palpation and the topographic Cone Beam Tomography (CBCT) examination confirms the anatomical variation of the tooth code 47. The diagnosis was previously initiated treatment with symptomatic apical periodontitis. The retreatment of the canals using the preflaring before using the Reciproc® System R25, for the biomechanical preparation technique, calcium hydroxide root canal medication was prescribed for 7 days, sodium hypochlorite as passive irrigation with and...
