introduction: ca(oh) 2 -containing/forming materials are conventionally used for indirect pulp-capping and are theoretically able to release ca 2+ and oh - ions for hydrolytic dissociation. however, no evidence exists for ion diffusion through the remaining coronal dentin. the aim of this study was to design an innovative experimental set-up to test the ability of ca(oh) 2 -containing and ca(oh...

We investigated the effects of Ga-Al-As laser irradiation on the mineralization ability of human dental pulp (HDP) cells and on Smads and bone morphogenetic protein (BMP) production as one mechanism for the transmission of laser photochemical energy to cells. HDP cells in vitro were irradiated once with a Ga-Al-As laser at 1.0 W for 500 s, and calcified nodule formation was assessed by Alizarin...

PURPOSE The purpose of this study was to investigate the morphology and calcification pattern of the styloid process (SP) and to determine their relations with subjects' age, gender, and dental status. MATERIALS AND METHODS 910 panoramic radiographs were stratified by age, dental status and gender. The distance between the points where SP leaves the tympanic plate of the temporal bone and the...

background: managing dental caries in young children is demanding due to the elusions present on the right diagnostic criteria for treatment. the present study evaluated the histological status of pulp tissues extracted from primary second molar with caries involvement. histological findings are correlated with clinical and radiographic assessment. materials and methods: simple experimental stu...

background: stem cells from human exfoliated deciduous teeth (shed) have the capability to differentiate into neural cells. neurotrophins including nerve growth factor (ngf), brain-derived neurotrophic factor (bdnf), neurotrophin-3 (nt-3), and neurotrophin-4 (nt-4) have neurogenesis, neurotrophic, or neuroprotective effects and are expressed in developing teeth. the aim of this study was to mea...

Vital pulp therapy (VPT) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. The purpose of this case report was to describe successful VPT of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. After complete caries removal and access ca...

Bioactive growth factors identified within the extracellular matrix of dentine have been proposed roles in regulating the naturally inherent regenerative dentine formation seen in teeth in response to trauma and infection, which may also be harnessed for novel clinical treatments in augmenting mineralised tissue repair. This study examined the specific biological action of demineralised dentine...

PURPOSE The purpose of this study was to repeat a 1997 survey of current pulp therapy practice. METHODS The directors of dental school predoctoral pediatric dentistry programs (N=56) and board certified pediatric dentists (N=1200) were surveyed in 2005. RESULTS More dental schools (83%) taught indirect pulp therapy (IPT) compared to 1997. Significantly more used glass ionomer for IPT with m...

The purpose of this study was to regenerate human dental pulp tissues similar to native pulp tissues. Using the mixture of type I collagen solution, primary cells collected from the different tissues (pulp, gingiva, and skin) and NIH 3T3 (1 × 10 cells/ml/well) were cultured at 12-well plate at 37°C for 14 days. Standardized photographs were taken with digital camera during 14 days and the diame...
