BACKGROUND Root fractures are a relatively rare type of injury with frequencies of 0.5-7% of traumatized permanent teeth. It is well known that teeth with intra-alveolar root fractures have a good prognosis. The pulp remains vital in about 80% of these teeth. If pulp necrosis develops, this normally only occurs in the coronal fragment. Although several studies on intra-alveolar root fractures h...

The purpose of the study was to ascertain the basic morphologic and kinematic characteristics of elite sprinters. The sample included 24 sprinters, with times over a 100 m distance between 10.21 s and 11.19 s. Morphologic characteristics of the sprinters were measured with a test battery of 17 measures, obtained according to the methodology prescribed by the International Biologic Programme (IB...

The aim of the present study was to evaluate the ability of thermal and electrical tests to register pulp vitality. Sensitivity, specificity, negative predictive value and positive predictive value were calculated by comparing the test results with a "gold standard". The thermal tests studied were a cold test (ethyl chloride) and a heat test (hot gutta-percha). For the electrical test, the Anal...

INTRODUCTION The purpose of this study was to compare the anesthetic efficacy of 0.5% bupivacaine with 1:200,000 epinephrine with that of 2% lidocaine with 1:100,000 epinephrine during pulpectomy in patients with irreversible pulpitis in mandibular posterior teeth. METHODS Seventy volunteers, patients with irreversible pulpitis admitted to the Emergency Center of the School of Dentistry at th...

OBJECTIVES This study was done to compare the anesthetic efficacy of 4% articaine with 1:100,000 epinephrine with that of 2% lidocaine with 1:80,000 epinephrine during pulpectomy in patients with irreversible pulpitis for inferior alveolar nerve block in mandibular posterior teeth. MATERIAL AND METHODS Patients with irreversible pulpitis referred to the Department of Conservative Dentistry an...

OBJECTIVE To compare the injection pain and speed of local anesthetic effect induced by tissue infiltration of mepivacaine 2% with epinephrine 1:100,000 versus articaine 4% with epinephrine 1:100,000 in securing mandibular first molar pulp anesthesia. MATERIALS AND METHODS Totally, 25 patients were recruited in a crossover, randomized, double-blind study. Each subject received injections of m...

AIM To measure excessive electrical stimulus time during pulp testing via electromyography (EMG) in the anterior belly of the digastric muscle, voice and finger movement, and to determine whether excessive stimulus time could be attenuated by a specially designed automatic circuit breaker on the basis of the EMG signal. METHODOLOGY The signals from three human responses (EMG, finger and voice...

Objective: To determine the diagnostic accuracy of cold test and electric Pulp testing for pulp vitality in single rooted teeth with irreversible pulpitis Materials & Methods: This cross-sectional study validation was carried out Operative dentistry department at Rehman College Dentistry Peshawar, from January 2019 to June 2019. Non-probability consecutive sampling technique used. Expected ...

Abstract Paper cultural relics such as double-sided printed newspapers and periodicals represent modern heritage. Severe damage embrittlement, decay, dreg generally occur to paper; hence, it urgently needs conservation restoration. Therefore, herein, a new reinforcement method for the fragile paper is proposed with cotton mesh adhesive PVA217 materials. Using computer measured controlled foldin...
