Improvements in technology have increased the level of patient care in all aspects of medicine and surgery. This is no less true in the area of cosmetic surgery. The use of endoscopy has led to improved aesthetics with respect to postoperative scarring, decreased healing time for patients, and an increase in overall patient satisfaction. Because the endoscopic brow and midface lift accomplishes...
Purpose of Review This review describes the recent findings from epidemiological studies on endodontic infections. The recent literature was screened for studies on the prevalence of primary apical periodontitis and posttreatment apical periodontitis in various populations. Recent Findings Twenty-nine articles reporting data on the prevalence of primary or posttreatment apical periodontitis f...
The aim of the study was to determine the most common causes of root canal failure in patients who reported to the operative department of AFID( Armed forces institute of dentistry) for retreatment. This was a cross sectional study carried out at the operative department of AFID Rawalpindi from January 2011 to December 2012. Among 200 patients included in the study,112 (56 %) were male and 88(4...
A problem that an endodontist can encounter during the course of root canal treatment is pain and swelling or both in the form of flare-ups. The causes for this flare-up are numerous which include mechanical, chemical, microbial injury to the pulp or periradicular tissues, whereby an acute periradicular inflammation results. This situation can be prevented by selection of instrumentation techni...
A thorough understanding of the histoanatomic structures and dynamic light interaction of the natural dentition provides dental practitioners with the ultimate strategic advantage with regard to optical integration of the final restoration. The first part of this article will attempt to provide insight on the threedimensional coronal configuration of natural teeth and on the utilization of this...
Clinical crown lengthening is a periodontal resective procedure aimed at partial removal of supporting periodontal tissues to increase exposure of coronal tooth structure. Crown-lengthening involves various techniques, including gingivectomy or gingivoplasty, apically positioned flap procedure, which may include osseous resection and forced tooth eruption with or without fiberotomy. Soft-tissue...
Correct positioning and alignment of components during primary total knee replacement (TKR) is widely accepted to be an important predictor of patient satisfaction and implant durability. This retrospective study reports the effect of the post-operative mechanical axis of the lower limb in the coronal plane on implant survival following primary TKR. A total of 501 TKRs in 396 patients were divi...
Effect of blood contamination on retention characteristics of MTA when mixed with different liquids.
Simulated furcation perforations were repaired with and without blood contamination utilizing tooth-colored mineral trioxide aggregrate (MTA) mixed with either MTA liquid (sterile water), lidocaine, or saline. Samples underwent Instron testing at either 24 or 72 hours and at 7 days. Data were analyzed using a 3-way ANOVA and post-hoc testing using Turkey's true test for significance. All of the...
19 The biological basis of endodontics is well established and underlines the dominant role of bacteria in the initiation, development and persistence of periapical disease (Kakehashi S et al, 1965) or apical periodontitis (AP) according to the terminology currently in use. The aim of clinical procedures is to prevent or eliminate bacterial infection from the root canal system (Orstavik D, Pitt...
The treatment of combined knee pathology is a challenging problem that requires careful attention to all aspects of the underlying disease. This is true of the interplay among malalignment and meniscal or articular cartilage restoration in the knee. Optimal outcomes are contingent on a comprehensive preoperative evaluation of patient-specific factors (patient expectations, patient age, and acti...
