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...

We compared clinicopathological characteristics of colorectal polyps, in order to investigate the hypothesis of neoplastic transformation of hyperplastic polyps. Of 4723 colonoscopies performed in our department over four years, 22 patients with 23 mixed hyperplastic polyps (MHAP) were found. These were compared with 61 patients with 86 hyperplastic polyps, 40 with 58 tubular adenomas and 27 wi...

External root resorption of permanent teeth is a multifactorial process. Several etiologic and predisposing factors have been related to external root resorption. Idiopathic external root resorption is defined as cases of external root resorption without a distinct etiologic factor. This article presents an extensive idiopathic external root resorption of maxillary first molar with irreversible...

Absence of Kupffer cells in rat liver hyperplastic nodules induced by a chemical carcinogen was demonstrated by intravenous injection of indian ink. Hyperplastic nodules appeared 4 weeks after diethylnitrosamine (DEN) was administered, and the nodules continued growing and became eosinophilic hyperplastic nodules after 5 to 6 weeks. After intravenous injection of indian ink, hyperplastic nodule...

Dental diseases are common in man and range from a toothache to cancers of the head and neck. Dental conditions can affect our capacity to function effectively in areas such as smiling, chewing and speaking. The objective of this study was to describe the main types of dental conditions presenting at the University Hospital between January 2006 and December 2011 and to determine factors associa...

INTRODUCTION The aim of the present study was to compare the efficacy of 2% lidocaine to 4% articaine in buccal infiltration of maxillary first molars with irreversible pulpitis. Moreover, the effect of root length on success of anesthesia irrespective of the type of anesthetic agent was assessed. METHODS AND MATERIALS Fifty patients suffering from painful maxillary first molars with irrevers...

High mobility group box 1 (HMGB1), a nonhistone DNA-binding protein, is released into the extracellular space and promotes inflammation. HMGB1 binds to related cell signaling transduction receptors, including receptor for advanced glycation end products (RAGE), which actively participate in vascular and inflammatory diseases. The aim of this study was to examine whether RAGE and HMGB1 are invol...

INTRODUCTION Similar to other tissues, the dental pulp mounts an inflammatory reaction as a way to eliminate pathogens and stimulate repair. Pulp inflammation is prerequisite for dentin pulp complex repair and regeneration; otherwise, chronic disease or pulp necrosis occurs. Evaluation of pulp inflammation severity is necessary to predict the clinical success of maintaining pulp vitality. Clini...

OBJECTIVES To evaluate the outcome of vital pulp therapy in primary teeth with irreversible pulpitis by using calcium-enriched mixture (CEM) cement according to clinical and radiographic assessment. PARTICIPANTS AND METHODS Fifty primary molar teeth with irreversible pulpitis in 50 children aged 6-8 years underwent pulpotomy using CEM cement as the dressing material. Following pulpotomy, pain...

Introduction The aim of this prospective, randomized, double-blind study was to investigate the effect of articaine combined with ketamine on the success rate of inferior alveolar nerve block (IANB) in posterior mandible teeth with symptomatic irreversible pulpitis. Methods and Materials Forty two adult patients with diagnosis of symptomatic irreversible pulpitis of a mandibular posterior too...
