INTRODUCTION: Thixotropic synthetic clays have been successfully used for tissue engineering in regenerative medicine. The impact of these clays on the dental pulp, in particular in combination with hypoxia-based approaches using hypoxia mimetic agents (HMAs), is unknown. Our aim was to reveal the response of dental pulp-derived cells (DPCs) to a synthetic clay-based hydrogel and evaluate the release of HMAs. METHODS: Using resazurin-based toxicity assays, live-dead staining, and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide staining, the viability of human DPCs seeded onto a synthetic clay-based hydrogel of 5%-0...

Cancer of the oral cavity and pharynx ranks eighth among the top 10 cancer sites in all United States males. Salivary gland tumors (SGTs) are uncommon, and malignancies in SGT are even more uncommon than benign tumors. Intraoral minor SGTs are rare, and when they do occur, the tumor is often benign. The purpose of this report is to present a case of a malignant, intraoral minor SGT mimicking a lesion of endodontic origin. Histopathologic analysis determined the tumor to be a high-grade mucoepidermoid carcinoma...

INTRODUCTION: In regenerative endodontic treatment (RET), practitioners favor the placement of bioceramics as sealing materials over blood clots. It is important to understand the interaction between sealing material and cells in the root canal. The purpose of this study was to compare the effectiveness of various bioceramic materials (ProRoot MTA [Dentsply, Tulsa, OK], Biodentine [Septodont, Saint-Maur-des-Fossés, France], and RetroMTA [BioMTA, Seoul, Korea]) as sealing materials in RET for the proliferation and differentiation of stem cells from the apical papilla (SCAPs)...

INTRODUCTION: Interferon regulatory factor 8 (IRF8) is a critical transcription factor in innate immune responses that regulates the development and function of myeloid cells. Human periapical lesions are caused by endodontic microbial infections. However, the presence of IRF8 in human periapical lesions remains elusive. This study aims to explore the expression of IRF8 in human periapical lesions and the possible association of IRF8 with macrophages, nuclear factor kappa B (NF-κB) signaling, and the autophagy process...

Autotransplantation is considered a standard procedure with a poorer prognosis for mature than for immature teeth. In this case report, the root tip of an almost fully developed tooth was resected during autotransplantation to fit into a deficient recipient site. As a positive side effect, the apical foramen was enlarged, with potential improvement of the probability of revascularization. Clinical and radiologic follow-up examinations up to 18 months indicated revascularization and uneventful periodontal regeneration and thus successful autotransplantation...

INTRODUCTION: An avulsion injury is a serious trauma to pulp and periodontal tissues. After avulsion and replantation, teeth are at risk of infection and root resorption, which may affect treatment outcome and survival rate. Thus, the purpose of this systematic review was to evaluate the incidence of root resorption after the replantation of avulsed teeth. METHODS: Two reviewers searched 7 electronic databases for observational studies involving human subjects that evaluated the incidence of root resorption after tooth avulsion...

Pulp canal calcification is characterized by the deposition of calcified tissue along the canal walls. As a result, the root canal space can become partially or completely obliterated. Recently, "guided endodontics" has been reported as an alternative solution in cases of partial or completed canal obliteration. Although this technique can enhance minimally invasive access to the calcified canal, it has been shown that the incisal surfaces are often removed during the access of anterior teeth. This report describes 2 cases of guided endodontics using conventional palatal access in calcified anterior teeth and discusses the applicability of this approach in cases of pulp canal calcification with apical periodontitis and acute symptoms...

INTRODUCTION: The nuclear enzyme poly(adenosine phosphate ribose) polymerase 1 (PARP-1) has been implicated in the maintenance and differentiation of several stem cells. The role of PARP-1 in dental pulp stem cell (DPSC) differentiation, especially in the context of its ability to modulate nerve regeneration factors, has not been investigated. Regeneration of neuronal components in pulp tissue is important for the assessment of tooth vitality. Brain-derived neurotrophic factor (BDNF) is known to play an integral signaling factor during nerve regeneration...
