Recent studies have revealed the existence of stem cells in various human tissues including dental structures. We aimed to establish primary cell cultures from human dental pulp and periodontal ligament, to identify multipotential adult stem cells in these cultures, and to study the differentiation capacity of these cells to osteogenic and to neuronal fates. Dental pulp and the periodontal liga...

Objective: the objective of the study was to determine the relationship between dental calcification stages and skeletal maturation in a Peruvian sample. Methods: panoramic, cephalometric and carpal radiographs of 78 patients (34 girls and 44 boys) between 7 and 17 years old (9.90 ± 2.5 years) were evaluated. Stages of tooth calcification of the mandibular canine, first premolar, second prem...

The vitality of the pulp is fundamental to the functional life of the tooth. For this aim, active and living biomaterials are required to avoid the current drastic treatment, which is the removal of all the cellular and molecular content regardless of its regenerative potential. The regeneration of the pulp tissue is the dream of many generations of dental surgeons and will revolutionize clinic...

The continuously growing rodent incisor is a widely used model to investigate odontogenesis and mineralized tissue formation. This study focused on evaluating the mouse mandibular incisor as an experimental biological tool for analyzing in vivo the capacity of odontoblast-like progenitors or bioactive molecules to contribute to reparative dentinogenesis. We describe here a surgical procedure al...

This study was carried out to determine the blood group from dentine and pulp and to correlate the same with blood collected from respective extraction socket. 30 teeth were extracted and stored dry for 6 months. An attempt to establish the blood group from dentin and pulp was made by Absorption–Elution method. The pulp showed positive results for 27 out of 30 teeth (sensitivity 90%). Two teeth...

dental follicle derived cells showed enhanced osteoblastspecific genes and ectopic bone formation after in vivo transplantation, indicating dental follicle is the powerful stem cell source in bone tissue regeneration. Dental pulp is expected to harbor the pools of undifferentiated precursor cells for nerve or vascular tissue regeneration. The most powerful advantage of dental tissues as stem ce...

An immature tooth with early irreversible pulp involvement presents with thin divergent or parallel dentinal walls. This situation creates clinical challenges in disinfection, and as a result, affects the long-term outcome of the treatment. Traditionally, calcium hydroxide has been used as the intra-canal medicament in apexification procedures. However, because of its high pH it will cause necr...

Low-level laser therapy (LLLT) has been reported to improve tissue healing and might therefore be useful in dental pulp capping after trauma. We evaluated the effects of a low-level diode laser (lambda = 680 nm) and dental pulp-capping substances on cell proliferation. Calcium hydroxide and adhesive resin were applied as conditioned media to cultures. Half of the samples received irradiation wi...

Currently, much information is provided regarding the presence and the roles in tissue regeneration of stem cell niches residing in post-natal dental pulp. So far, three types of adult stem cells have been isolated from dental pulp. Correct evaluation of these cells is important in order to determine their potential use in clinical fields. The present study aims to review the origins and immuno...

Dental decay prevalence in the primary dentition continues to maintain high levels in the infant population, despite the efforts and advances that have been made in the field of oral health prevention programs [1]. This situation increases the possibilities of pulp involvement due to the presence of deep caries, leading pulp to an irreversible state, implying the need to perform a pulp treatmen...
