INTRODUCTION This report presents a case of impacted lower third molar extracted for surgical reasons in patient with uncontrolled hepatitis C. After decalcification, dental pulp vasculature and its tissue quality were investigated. METHODS Serial sections of 4-μm thickness along the midline buccolingually for the demineralized specimen were obtained, mounted on a glass slide, stained with he...

Calcifying nanoparticles (CNPs, previously called nanobacteria) are self-propagating, cultivable macromolecular complexes. Their extraordinary characteristic is that they can aggregate carbonate apatite on their envelope from soluble calcium and phosphorus at physiologic concentrations and display cytotoxic effects on murine and human fibroblast cell lines. The question arises whether CNPs cont...

Introduction: Nanobacteria have been implicated in the formation of pathogenic calcifications e.g. kidney stones, arterial plaque, calcified cardiac valves, dental pulp stone, etc. It has been hypothesized that nanobacteria may be present in dental calculus which has a similar mineralization formation process and that nanobacteria may play an efficient role in the calcification of dental calcul...

Background: Pulp stones are calcification in the dental pulp which can be present either in deciduous or permanent teeth. Exact causes of pulp stones are not known and several elements have been associated. It can be seen in healthy, diseased or as a part of various syndromes. Frequency of pulp stones fluctuated from 8 to 95% depending on the population studied. Our study is an attempt to know ...

INTRODUCTION Over the past century, the dental literature has consistently reflected a controversy related to the effect of periodontal disease on the dental pulp. Nonetheless, practitioners are of the opinion that teeth having deep periodontal pockets show variable pulpal response, which may necessitate root canal treatment. Thus, this study aimed to evaluate the changes in pulp due to advance...

Aim: Dental pulp has various characteristics in the pulp chamber, but only a few biological evaluations about the effect of age on dental pulp tissue have been reported. The purpose of this study was to compare dental pulp from young and from adult rats to characterize the homeostatic mechanism. Methodology: Dental pulp cells (DPCs) were obtained from the first molar of rats, weighing 150 g eac...

Pulp stones are foci of calcification or discrete calcifications in the dental pulp. They are frequently found on bitewing and periapical radiographs, but their occurrence in entire dentition is unusual. We are reporting four cases in which the occurrence of pulp stones ranged from their presence in just primary teeth (Cases 1 and 2) to involvement of young permanent teeth also (Case 3) and eve...

A 32-year-old male patient came to the department of oral medicine and radiology with a chief complaint of discoloured teeth in upper front tooth region since 2 years. He gave no history of pain and a history of fall 4 years ago. Past medical and dental history were noncontributory. Intraoral examination revealed yellowish discoloration of coronal aspect of left maxillary central incisor (Figur...

Pulp calcifications stones are discrete calcifications within the pulps of teeth. They are a frequent finding on bitewing and periapical radiographs. Johnson and Bevelander stated that a single tooth may have stones ranging from 1 to 12 or even more, with sizes varying from minute particle to large masses that occlude the pulp space. They often develop in teeth that appear quite normal in other...

Pulp stones are a frequent finding on bitewing and periapical radiographs but receive relatively little attention in textbooks. A review of the literature was therefore performed, initially using the PubMed database and beginning the search with 'pulp calcifications' and 'pulp stones'. Each term provided more than 400 references, many of which related to pulp calcification in general rather tha...
