ABSTRACT
Últimamente, el uso del láser en endodoncia ha ganado aceptación llegando a considerarse como un complemento a la terapia endodóntica, la cual tiene como objetivo realizar una efectiva conformación, limpieza y desinfección del sistema de canales radiculares (SCR), permitiendo una eliminación eficaz de microorganismos presentes, y así prevenir la reinfección del canal. Se han adoptado diferentes métodos de aplicación del láser para mejorar la desinfección del SCR, los cuales podrían ser eficaces para reducir la población microbiana presentes al interior de los canales, por medio de la activación del irrigante utilizado. El empleo de láser también podría ser útil en procedimientos endodónticos quirúrgicos los cuales tienen por objetivo mantener el diente y sus raíces cuando el tratamiento convencional ha fallado, los efectos positivos del láser se centrarían en el descenso de la inflamación y del aumento de volumen, además de la disminución de la filtración de los materiales de sello ortógrado en dientes apicectomizados. Otro de los usos de láser en esta materia está relacionado con el manejo del dolor post-terapia endodóntica, el que se ha visto ser prometedor. Se definen dos tipos de láseres: de baja potencia, que produce una acción bioestimulante, analgésica y antiinflamatoria de los tejidos biológicos, utilizada además en procesos de descontaminación del SCR, y de alta potencia o láser quirúrgico, con el que se pueden realizar incisiones, exéresis, realizando funciones de corte y coagulación.
Lately, the use of laser in endodontics has gained acceptance, being considered as a complement to endodontic therapy, which aims to carry out an effective shaping, cleaning and disinfection of the root canal system (RCS), allowing an effective elimination of microorganisms present, and thus prevent reinfection of the canal. Different laser application methods have been adopted to improve the disinfection of the RCS, which could be effective in reducing the microbial population present inside the canals, by activating the irrigant used. The use of laser could also be useful in surgical endodontic procedures which aim to maintain the tooth and its roots when conventional treatment has failed, the positive effects of laser would focus on reducing inflammation and increasing volume, in addition of the reduction in the filtration of orthograde seal materials in apicoectomized teeth. Another use of laser in this area is related to post-endodontic therapy pain management, which has shown promise. Two types of lasers are defined; low-power, which produces a biostimulant, analgesic and anti-inflammatory action of biological tissues, also used in RCS decontamination processes, and high-power or surgical laser, with which incisions, excision, performing cutting functions and coagulation.

OBJECTIVES: The purpose of this research was to identify the top 10 most-cited articles on the management of fractured or broken instruments and to perform a bibliometric analysis thereof. MATERIALS AND METHODS: Published articles related to fractured instruments were screened from online databases, such as Web of Science, Scopus, PubMed, and ScienceDirect, and highly cited papers, with at least 50 citations since publication, were identified. The most-cited articles were selected and analysed with regard to publication title, authorship, the journal of publication, year, institution, country of origin, article type, and number of citations. RESULTS: The top 10 most-cited articles were from various journals. Most were published in the Journal of Endodontics, followed by the International Endodontic Journal, and Dental Traumatology. The leading countries were Australia, Israel, Switzerland, the USA, and Germany, and the leading institution was the University of Melbourne. The majority of articles among the top 10 articles were clinical research studies (n = 8), followed by a basic research article and a non-systematic review article. CONCLUSIONS: This bibliometric analysis revealed interesting information about scientific progress in endodontics regarding fractured instruments. Overall, clinical research studies and basic research articles published in high-impact endodontic journals had the highest citation rates.

Background: Root canal preparations done using many rotary endodontic instruments results in formation of root dentin defects because of the stress induced by the instruments within the root canal during cleaning and shaping, thereby worsening the long term prognosis of the root canal treated teeth. Many rotary instruments are been globally studied for the purpose of generating a correct instrument for root canal preparation. Objective: This study was done to evaluate the effect of HyFlex EDM, which is a new rotary system on root dentin during root canal preparation. Materials and methods: Fourteen single rooted premolars were selected and divided into two groups, Group 1-Protaper Universal and Group 2-HyFlex EDM. All the specimens were decoronated. Roots of each specimen were sectioned at 3mm, 6mm and 9mm and were then viewed under stereomicroscope for dentinal defects. t-test was done for the statistical analysis and level of significance was set at p=0.05. Results: Protaper Universal showed highest percentage of defect than HyFlex EDM. Conclusion: HyFlex EDM showed lowest percentage of defects in root dentin. Thus, HyFlex EDM is more efficient in root canal preparation than that of Protaper Universal thereby preventing dentinal defects or microcracks leading to root fractures.

ABSTRACT
Background: Among all the microbial organisms Enterococcus faecalis and Candida albicans were the most commonly seen and most resistant organisms in persistent or failing root canals. Even after chemomechanical preparations and treatment 40 to 70% of the microorganisms survive. Aim: This in vitro study was done to evaluate the antimicrobial efficacy of intra canal medicament in root canals charged with Enterococcus faecalis. Materials and methods: Forty eight extracted human single rooted teeth were taken. Biomechanical preparations and access preparations were done. Specimens were sterilized by autoclaving and later contaminated with Enterococcus faecalis and incubated for 24 hours. Confirmation of Enterococcus faecalis was done and then divided into 3 experimental and 2 control groups. Groups (n=12) A) Animireddy Kishore, G. Obulesu, Madhu Babu. Determination of Antimicrobial Efficacy of Calcium hydroxide, Ozonated sesame oil and their combination as intra canal medicament against Enterococcus faecalis – A Study in Fathima Institute of Medical Sciences, Kadapa. IAIM, 2016; 3(8): 219-227. Page 220 Ozonized Sesame Oil, B) Calcium Hydroxide, C) Calcium Hydroxide + Ozonised Sesame Oil. Control groups Group 1:- (n=6) Negative Control, Group 2:- (n=6) Positive Control. Intra canal medicament was placed in each root canal corresponding to the groups and incubated at 370C. First sampling was done after 24 hours and second or final sampling was done after 72 hours of placement of intra canal medicament. Microbial growth was checked by counting CFU (Colony Forming Units). Results: In the first sampling ozononised sesame oil was 100% efficient, next efficient was Calcium Hydroxide group, and combination of Ozonised sesame oil and Calcium Hydroxide also showed almost similar results. But in the second and final sampling after 72 hours Ozonised sesame oil was highly efficient when compared to other two groups. Calcium Hydroxide was moderately efficient whereas combination of both the drugs was least effective as it showed highest CFU/ml. Conclusion: Ozonised sesame oil was most effective for longer duration when compared to other groups and can be used as an alternative intra canal medicament.
