BACKGROUND: 1,25-dihydroxyvitamin D3 (1,25-OH D3) plays an important role in mineralized tissue metabolism, including teeth. However, few studies have addressed its role in odontoblastic differentiation of human dental pulp-stem cells (hDPSCs). AIM: This study aimed to understand the influence of various concentrations of 1,25-OH D3 on the proliferation capacity and early dentinogenesis responses of hDPSCs. MATERIALS AND METHODS: hDPSCs were obtained from the impacted third molar teeth...

Mandibular tooth impaction is a very common finding and is usually associated with so many local and systemic causes in which the pathway of tooth eruption is obstructed or misdirected. The local causes are either a local bony lesion or an abnormal position of the adjacent tooth. The case presented here is associated with a very rare cause of impaction, which is the hamartomatus growth of the first and second molars causing the obstruction and leading to the impaction of the adjacent third molar tooth.

INTRODUCTION: The removal of impacted teeth is one of the most common procedures performed by oral and maxillofacial surgeons. Reduction of discomfort post-operatively and efficient local anesthesia are imperative for success in surgical practice. At sub-anesthetic doses, ketamine has a noticeable analgesic action, which can be used to supplement local anesthesia with minimal side effects. AIM: To assess the efficacy of low-dose ketamine as an adjunct to local anesthesia in the management of pain, swelling and trismus after surgical removal of impacted mandibular third molars...

Mandibular third molars are commonly removed because of distal caries in the adjacent tooth. To find out the prevalence of distal caries in mandibular second molars we retrospectively studied the primary care dental records of 720 British military personnel (653 men and 67 women) from various centres. These records are standardised and personnel are required to attend for inspection regularly. Those who had been under 20 years of age at enlistment, who had served for at least five years, and had five recorded dental inspections, were included...

Dentigerous cysts are benign odontogenic cysts that are accompanying with the crown of permanent teeth. They are typically single in incidence and are situated in the mandible. They are usually associated with impacted mandibular third molar and maxillary canines. Here we report a very rare presentation of dentigerous cyst in anterior maxilla accompanying with ectopically impacted maxillary second premolar. The cyst was enucleated along with extraction of premolar.

The keratocystic odontogenic tumor, although a benign lesion, is peculiarly aggressive with a high recurrence rate. Its involvement with the maxillary antrum is atypical. We report the unusual case of a 20-year-old male patient with an extensive antral tumor associated with an impacted third molar, which was initially misdiagnosed as a dentigerous cyst. Clinical, radiographic, and histopathologic aspects were analyzed to provide useful information for the correct diagnosis, treatment, and prognosis within a multidisciplinary approach...

Many authors have studied various different parameters in relation to postoperative anxiety after the extraction of third molars. However, the effect that the acute inflammatory process occurring post extraction could have on these parameters has not been studied. Certain salivary biomarkers, although not specifically inflammatory, may be affected by the acute inflammatory process occurring following the extraction of a retained lower third molar. Three biomarkers were assessed in this study: total protein, immunoglobulin A (IgA), and alpha-amylase...

BACKGROUND: Successful pulp regeneration depends on identification of pulp stem cells capable of differentiation under odontoblastic lineage and producing pulp-dentinal like structure. Recent studies demonstrate that platelet-derived growth factor (PDGF) plays an important role in damage repair and tissue regeneration. The aim of this study was to identify a subpopulation of dental pulp cells responsive to PDGF and with dentin regeneration potential. METHODS: Pulp tissues were isolated from 12 freshly extracted human impacted third molars...
