Assessment of Intraobserver and Interobserver Agreement of a New Classification System for Retrograde Periimplantitis.

Background: Retrograde periimplantitis (RPI) is the inflammatory disease that affects the apical part of an osseointegrated implant while the coronal portion of the implant sustains a normal bone-to-implant interface. The aim of the current study was to assess the intraexaminer and interexaminer reliability of a proposed new classification system for RPI.

Materials And Methods: After thorough electronic literature search, 56 intraoral periapical radiographs (IOPA) of implants with RPI were collected and were classified by 2 independent reviewers as per the new classification system into one of the 3-mild, moderate, and advanced-classes based on the amount of bone loss from the apex of the implant to the most coronal part as a percentage of the total implant length.

Evaluation of Spontaneous Bone Regeneration after Enucleation of Large Cysts of the Jaws using Radiographic Computed Software.

Introduction: Spontaneous regeneration of bone is commonly seen in the small surgical defects caused by enucleation of cysts. However, in case of large surgical defects caused by the enucleation, spontaneous regeneration of bone is a rare phenomenon and it depends on factors, such as age of the patient, intact periosteum, and proper stabilization.

Materials And Methods: The study included 16 patients, who reported to the department of oral and maxillofacial surgery with the complaint of pain and swelling in the jaws diagnosed as cyst.

Comparative Evaluation of Shear Bond Strength and Fluoride Release of Conventional Glass Ionomer with 1% Ethanolic Extract of Propolis Incorporated Glass Ionomer Cement -Invitro Study.

Introduction: Atraumatic restorative treatment is a minimal intervention approach which involves manual removal of caries followed by restoration using adhesive restorative material. Due to incomplete manual caries excavation, there is a high chance of secondary caries under the restoration. Hence, many antibacterial agents have been incorporated in cement to enhance their antibacterial effect.

Assessment of interns and postgraduate dental student's knowledge regarding equipment ergonomics.

Context: The substantial knowledge concerning ergonomics and its practical application is vital for forestalling musculoskeletal disorders. The role of equipment ergonomics (EE) in preventing these work-related ailments is significantly noteworthy.

Aim: The aim of the study was to assess the prevailing perception of postgraduates (PGs) and interns regarding EE and preparing the Indian dental workforce for the challenges of India's growing economy and population.

Ozone- A Biological Therapy in Dentistry- Reality or Myth?????

The usage of ozone in dentistry has been proposed because of its antimicrobial, disinfectant, biocompatibility and healing properties. In the last decade a number of therapeutic protocols with ozone have been developed to address common dental infections associated with periodontal disease, RCT and caries. Despite these advantages, therapeutic ozone's application in dentistry is limited because of its possible side effects.

A Radiographic Classification for Retrograde Peri-implantitis.

Background: Retrograde peri-implantitis (RPI) is an inflammatory disease that affects the apical part of an osseointegrated implant, while the coronal portion of the implant sustains a normal bone-to-implant interface. It is a diagnostic and therapeutic dilemma for implantologists. There is lack of a standard classification system and a definite treatment algorithm for the same.

Comparison of Skin Staples and Standard Sutures for Closing Incisions After Head and Neck Cancer Surgery: A Double-Blind, Randomized and Prospective Study.

Purpose: To investigate the merits and demerits of stapled skin closure when compared to conventional sutures in head and neck cancer surgery.

Materials And Methods: A total of 80 patients (40 patients each in control and study group) were enrolled. The patients underwent closure of incision wounds following head and neck cancer surgical procedures.

Pre-Emptive Analgesia with Ketamine for Relief of Postoperative Pain After Surgical Removal of Impacted Mandibular Third Molars.

Purpose: In this study we assessed the clinical efficacy of sub-mucosal injection of ketamine at sub-anesthetic dose of 0.5 mg/kg on post-operative pain, swelling and trismus following surgical extraction of impacted mandibular third molars.

Reciprocating vs Rotary Instrumentation in Pediatric Endodontics: Cone Beam Computed Tomographic Analysis of Deciduous Root Canals using Two Single-file Systems.

Background: Primary root canals are considered to be most challenging due to their complex anatomy. "Wave one" and "one shape" are single-file systems with reciprocating and rotary motion respectively. The aim of this study was to evaluate and compare dentin thickness, centering ability, canal transportation, and instrumentation time of wave one and one shape files in primary root canals using a cone beam computed tomographic (CBCT) analysis.
