Chronic periodontitis is one of the most frequent and severe diseases involving the tooth. Untreated, they can lead to tooth loss. Our study involved 67 patients with chronic marginal periodontitis who underwent tooth extraction, of which 29 had moderate periodontal lesions and 38 severe periodontal lesions. The microscopic study of the dental pulp revealed significant changes in all patients. ...

Odontogenic infections can result from several conditions, such as pulp necrosis, periodontal disease, pericoronitis, trauma, or surgery.  The three types of odontogenic dental abscesses are endodontal periapical, periodontal, and pericoronal, depending on where the infection first developed. Periodontal abscesses, which particularly common in people with untreated disease patients during ...

Restorative and endodontic procedures have been recently developed in an attempt to preserve the vitality of dental pulp after exposure to external stimuli, such as caries infection or traumatic injury. When damage to dental pulp is reversible, pulp wound healing can proceed, whereas irreversible damage induces pathological changes in dental pulp, eventually requiring its removal. Nonvital teet...

Dens evaginatus is a disturbance in tooth formation that appears clinically as an accessory occlusal tuberculated cusp composed of enamel and dentin, usually enclosing pulp tissue. The tubercle often fractures or is worn away, with subsequent pulp exposure leading to pulpal inflammation, necrosis, and periapical inflammation. When this happens to an immature tooth, diagnosis may be complicated ...

Bacterial, mechanical, or chemical irritation to the pulp may result in tissue necrosis and release of disintegration by-products that may penetrate tubules and discolor the surrounding dentin. The degree of discoloration is directly related to how long the pulp has been necrotic. The longer the discoloration compounds are present in the pulp chamber, the greater the discoloration. Such discolo...

INTRODUCTION The aim of the present investigation was to compare the efficacy of mineral trioxide aggregate (MTA) and 0.2% chlorhexidine (CHX) mixture to pure MTA, as a pulp capping material. METHODS AND MATERIALS The pulp of 24 lateral incisors and canines from four dogs were exposed and capped either with MTA or MTA+0.2% CHX. After 2 months the animals were sacrificed and the teeth were pre...

Regeneration (revitalization) of infected necrotic pulp tissue has been an important issue in endodontics for more than a decade. Based on a series of case reports, there appears to be evidence that new soft tissue can enter the root canal with a potential for subsequent hard tissue deposition resulting in a narrowing of the root canal. Very little is presently known about the exact nature of t...

External inflammatory root resorption (EIR) represents a challenge in endodontic practice. EIR commonly occurs after dental trauma that results in periodontal ligament injury, pulp necrosis and subsequent infection.  Treatment of EIR is based on disinfecting the root canal system through chemomechanical procedures and then filling it with calcium hydroxide or triple antibiotic paste. Dental tra...

Interactions between ingrowing nerve fibers and their target tissues form the basis for functional connectivity with the central nervous system. Studies of the developing dental pulp innervation by nerve fibers from the trigeminal ganglion is an excellent example of nerve-target tissue interactions and will allow specific questions regarding development of the dental pulp nerve system to be add...

Regeneration of dental pulp after pulpectomy was accomplished recently by autologous transplantation of dental pulp stem/ progenitor cells into the root canal. The identical patterns of qualitative and quantitative protein and mRNA expression in the regenerated pulp and normal pulp demonstrated complete pulp regeneration. The lack of tissue specific markers in the dental pulp is a major challen...
