BACKGROUND The aim of this study was to review the orofacial manifestations in patients with sickle cell disease (SCD). METHODS Indexed databases were explored using various combinations of the following keywords: "sickle cell anemia," "sickle cell disease," "oral health status" and "dental inflammation." RESULTS Hypoxia has been associated with osteomyelitis of the jaws, particularly the m...

dental pulp stem cells (dpscs) can be found within the cell rich zone of dental pulp. these stem cells, under specific stimuli, differentiate into many cell types which have wide therapeutic applications.   the dental stem cells are derived from both deciduous and permanent teeth. the viable dental stem cells are very simple to collect, without any mortality and morbidity. dental pulp stem cell...

Clinically, irreversible pulpitis is treated by the complete removal of pulp tissue followed by replacement with artificial materials. There is considered to be a high potential for autologous transplantation of human dental pulp stem cells (DPSCs) in endodontic treatment. The usefulness of DPSCs isolated from healthy teeth is limited. However, DPSCs isolated from diseased teeth with irreversib...

introduction: this study was designed to evaluate the prevalence of referred pain with pulpal source in the head, face and neck region among patients referred to dental school of shahid beheshti university mc, tehran, iran in 2004. materials and methods: in this cross-sectional study, 100 patients (55 males and 45 females) referred to oral medicine department of shahid beheshti dental school ev...

Dental pulp represents a promising and easily accessible source of mesenchymal stem cells for clinical applications. Many studies have investigated the use of human dental pulp stem cells and stem cells isolated from the dental pulp of human exfoliated deciduous teeth for bone tissue engineering in vivo. However, the type of scaffold used to support the proliferation and differentiation of dent...

We characterized a voltage-dependent ionic current in dental pulp cells on dental pulp slices using a nystatin perforated-patch recording configuration. The outward currents in dental pulp cells were inhibited by the following channel blockers: 1) Ca(2+)-free extracellular solution containing 10 mM Ba2+, 2) extracellular 400 nM apamin and 3) extracellular 300 nM 4,4'-diisothiocyanatostilbene-2,...

There are several studies about the cytotoxic effects of dental materials in contact with the pulp tissue, such as calcium hydroxide (CH), adhesive systems, resin composite and glass ionomer cements. The aim of this review article was to summarize and discuss the cytotoxicity and biocompatibility of materials used for protection of the dentin-pulp complex, some components of resin composites an...

Sinus on the chin can be the result of a chronic apical abscess due to pulp necrosis of a mandibular anterior tooth. The tooth is usually asymptomatic, and a dental cause is therefore not apparent to the patient or the unsuspecting clinician. Not infrequently, the patient may seek treatment from a dermatologist or general surgeon instead of a dentist. Excision and repair of the fistula may be c...

Thermal insult to pulpal tissue is recognized as a major limitation to the use of lasers for dental hard-tissue procedures. This study examined thermal changes at the level of the dental pulp in human molar teeth irradiated with a CO2 dental laser using a pulsed mode of operation. Sectioned molar teeth were exposed, in vitro, to CO2 laser radiation. The laser parameters were those used clinical...

Facial trauma that results in fractured, displaced or lost teeth can have significant negative functional, esthetic and psychological effects on children. An acute dental trauma may imply impact to the hard dental tissues and damage to the pulp and periodontium, ultimately leading to partial or total pulp necrosis and/or root resorption. Apexification is a commonly used procedure for treating a...
