Microscopy in Endodontics: A Bibliometric Survey.

Background: Microscopy is a resource used in endodontics as an aid in the study of pulp and periapical pathologies; it has allowed Endodontics to become more accurate, less invasive and has enabled greater chances of success in treatment. We aimed to map the scientific production on "microscopy" and "endodontics" in the databases, the ISI Web of Knowledge/Web of Science .

Methods: This bibliometric survey was conducted using ISI Web of Knowledge/Web of Science database, in the time frame between the years 1945 and 2016, the first being found in 1981.

Bone repair in defects filled with AH Plus sealer and different concentrations of MTA: a study in rat tibiae.

Objectives: This study aimed to evaluate the effects on bone repair of different concentrations of mineral trioxide aggregate (MTA) added to AH Plus.

Materials And Methods: Bone tissue reactions were evaluated in 30 rats () after 7 and 30 days. In the AH + MTA10, AH + MTA20, and AH + MTA30 groups, defects in the tibiae were filled with AH Plus with MTA in proportions of 10%, 20% and 30%, respectively; in the MTA-FILL group, MTA Fillapex was used; and in the control group, no sealer was used.

Medication-Related Osteonecrosis of the Jaw and Low-Level Laser Therapy as Adjuvant Treatment: A Case Report.

Medication-related osteonecrosis of the jaw (MRONJ) occurs by the use of a drug that has osteonecrosis as one of its side effects. We describe a case of a 48-year-old oncological patient who had brain and bone metastasis due to breast cancer and was medicated with bisphosphonates (BPs). She presented cavities, and after an incorrect exodontia, the lesion evolved into a jaw osteonecrosis.

Alternative techniques to remove fractured instrument fragments from the apical third of root canals: report of two cases.

This paper describes two cases of instrument fragment removal from the apical thirds of root canals using a customized extractor and a modified needle technique, respectively. In case 1, a customized extractor was manufactured to remove a bur fragment located in the apical root canal of a maxillary central incisor. The use of this extractor enabled successful and conservative removal of the instrument fragment.
