Management of luxation injuries in line with International Association of Dental Traumatology guidelines - Two case reports.

Luxation injuries represent significant traumatic events for permanent teeth. This article presents the management of intrusive and extrusive luxation injuries, following the International Association of Dental Traumatology (IADT) guidelines, through two case reports. The first case involves a 30-year-old female with an intruded maxillary left central incisor, managed through surgical extrusion, stabilization, and endodontic treatment.

Comparative Evaluation of Different Apex Locators as a Diagnostic Tool to Detect Root Perforations: An Study.

Aim: The purpose of this study was to determine how effectively four distinct apex locators could diagnose root perforations in terms of accuracy and repeatability.

Materials And Methods: Eighty mandibular premolars with a single root were instrumented. The distal face of the root was perforated at both the apical and middle thirds, five millimeters from the apical terminus.

Analysis of cyclic fatigue resistance of different endodontic nickel-titanium rotary instruments: An study.

Aims: The aim of this study was to compare the cyclic fatigue resistance of three different endodontic nickel-titanium rotary instruments using a dynamic testing device.

Materials And Methods: Ten files each of ProTaper Gold (PG), Hyflex Electro-discharge Machining (HEDM), and TruNatomy (TN) were tested in a custom-fabricated dynamic cyclic fatigue testing device at 60° curvature having a radius of curvature of 5 mm. The number of cycles to the fracture (NCF) of each instrument was calculated and three continuous groups were compared by the Kruskal-Wallis test and Dunn test was used for pairwise comparison.

Comparative Evaluation of Root Canal Transportation and Centering Ability in Curved Mesiobuccal Canals of Mandibular First Molars after Instrumentation with Different File Systems-An Study.

Aim: To assess the canal transportation and centering ability in the mandibular first molars' curved mesiobuccal canals after instrumentation with file systems XP endo Shaper, self-adjusting File (SAF), Hyflex EDM, Pro Taper NEXT, WaveOne Gold, and K files with the help of Cone-Beam Computed Tomography (CBCT).

Materials And Methods: Ninety recently extracted mandibular first molars with mesiobuccal roots that had a 25-30 degree canal curvature were assessed. Following preoperative CBCT scans, teeth were allocated randomly to six experimental groups of fifteen.

A Rare Occurrence of Bilateral Single-Rooted Mandibular First Molar.

It is essential to have an in-depth knowledge of root and root canal anatomy to prevent any iatrogenic errors. Many studies and case reports are present in the literature related to the anatomy of mandibular first molars, but most of them are on an extra number of roots and root canals. There are few studies related to a lower number of roots and root canals, but the occurrence of bilateral mandibular first and second molars with the presence of root fusion resulting in a single root is very rare.

Revisiting amalgam: a comparative study between bonded amalgam restoration and amalgam retained with undercuts.

Aim: To compare the retention of amalgam restorations in bonded amalgam restoration and restorations with undercuts.

Background: With improvement in adhesive technology problem associated with conventional preparation for amalgam restorations mainly compromised resistance form of tooth structure have been largely overcome.

Materials And Methods: Forty caries free extracted molars were used.

Tuberculosis and pregnancy--Results of a study in a high prevalence area in London.

Objective: The aim of the study was to characterise the incidence, type and presentation of tuberculosis in pregnancy over a 5-year period in women booked for antenatal care in a District General Hospital located in a high prevalence area in London. We also aimed to identify any problems and difficulties in the diagnosis and management of tuberculosis associated with pregnancy.

Design: Retrospective review of computer records and hospital notes over a period of 5 years from January 1997 to December 2001.

Improving the quality of cervical screening.

Objective: To compare the adequacy of cervical cytology sampling by a newly designed cervical cell sampler (the implement) with a commonly used, extended tip cervical scraper, namely the Jordan's spatula, by assessing the quality of cervical smears obtained.

Design: Prospective randomised controlled trial, with the approval of the local Ethics Committee after informing the Medical Devices Agency in the UK.

Setting: Colposcopy Clinic in a District General NHS Trust Hospital in London.
