Comparative evaluation of efficacy of different irrigation devices in removal of calcium hydroxide in teeth with simulated internal resorption cavities - An study.

Aim: The aim of this study was to compare the efficacy of newly developed irrigation systems, i.e., XP-endo Finisher file (XP-endo), EndoActivator (EA), and Endo-Irrigator Plus (EI) with gold standard passive ultrasonic irrigation (PUI) tip and in removal of calcium hydroxide (CH) from single-rooted teeth with artificial simulated internal resorption cavities.

Shaping Ability of 2Shape and WaveOne Gold Files Using Cone-Beam Computed Tomography.

Aim And Objective: The aim of this study is to evaluate the apical transportation, centering ability, and volume of removed dentin of WaveOne Gold (WOG) and 2Shape with the use of cone-beam computed tomography.

Materials And Methods: Freshly extracted mandibular teeth with sample size of thirty were carefully chosen and instrumented using the 2Shape and WOG rotary files. Preoperative and postinstrumentation cone-beam computed tomographic scans were done to accomplish mesial and distal dentin walls' measurements and volume of removed dentin calculations, apical transportation, and centering ratio.

Comparative Study of the Effect on Apical Sealability with Different Levels of Remaining Gutta-Percha in Teeth Prepared to Receive Posts: An Study.

Objective: The objective of this study is to compare the apical sealability of mineral trioxide aggregate (MTA) Fillapex and Endosequence BC sealer at three different lengths of remaining gutta-percha after postspace preparation.

Materials And Methods: A total of 80 freshly extracted human maxillary anterior teeth were decoronated, biomechanically prepared, and randomly divided into four groups; Group A and Group B served as positive and negative control with 10 teeth each. The teeth in Group C and Group D (with 30 teeth each) were obturated with gutta-percha using MTA Fillapex sealer and Endosequence BC sealer, respectively.

Scrub typhus: A prospective, observational study during an outbreak in Rajasthan, India.

Background: Scrub typhus, a potentially fatal rickettsial infection, is common in India. It usually presents with acute febrile illness along with multi-organ involvement caused by Orientia tsutsugamushi. As there was an outbreak of scrub typhus in the Hadoti region of Rajasthan and there is a paucity of data from this region, we studied this entity to describe the diverse epidemiological, clinico-radiological, laboratory parameters and outcome profile of patients with scrub typhus in a tertiary care hospital.

Tubercular osteomyelitis of calcaneum bone: A rare occurrence.

In spite of the endemic nature of tuberculosis in India, skeletal tuberculosis is relatively infrequent. Involvement of foot bones is uncommon and isolated calcaneum is even rarer. Osteoarticular tuberculosis is a diagnostic enigma, as the characteristic signs and symptoms of this disease may be absent, or mimic other disorders, leading to emergence of complications and therapeutic delay, particularly when the disease affects unusual sites.

Effect of 10% Sodium Ascorbate on Shear Bond Strength of Bleached Teeth - An in-vitro Study.

Background: Patient often requires some additional interventions such as replacement of old restorations, laminates and veneers after bleaching, for aesthetic purposes. The residual oxygen inhibits polymerization of resin based materials which results in reduced bond strength of the restorations. Some techniques are available to solve the clinical problems related to the post bleach compromised bond strength.

Cone beam computed topographic evaluation and endodontic management of a rare mandibular first molar with four distal canals.

Root canal system is complex to understand because of its unpredictable nature. It differs for different teeth and for the same teeth in different individuals. Successful endodontic therapy thus depends on the clinician's ability to anticipate and look for these variations.
