dental pulp capping

Background and objectives Direct pulp capping (dPC) is a therapeutic process that involves the application of a protective chemical to an exposed pulp with the intent to facilitate the restoration and preservation of its vitality and function. Despite numerous proposed solutions, researchers have yet to find a dependable, non-absorbable bioactive pulp capping substance that constantly activates cellular healing processes, consequently preserving pulpal vitality over an extended period of time. The objective of this study was to assess and contrast the efficacy of a novel tricalcium silicate cement and calcium hydroxide in preserving the long-term health of the dental pulp following dPC using clinical and radiographic observations...

BACKGROUND Vital pulp therapy approaches are preferred over non-surgical root canal treatment, giving the advantage of preserving the vitality of the dental pulp and thus maintaining its benefits. Such approaches can be performed in teeth having normal apical area; however, performing vital pulp therapy approaches in teeth associated with periapical pathology remains controversial. CASE REPORT We present a case of a mature mandibular right first permanent molar tooth in a medically fit 10-year-old female diagnosed as asymptomatic irreversible pulpitis with asymptomatic apical periodontitis with periapical radiolucency having a periapical index (PAI) score of 4...

BACKGROUND: Pre-eruptive intra-coronal radiolucency (PEIR) is a rare dental anomaly often incidentally detected during routine radiographic examinations. This condition manifests as a radiolucent lesion beneath the enamel-dentinal junction of unerupted teeth, particularly in lower molars, posing diagnostic and management challenges due to its asymptomatic nature. The treatment of PEIR depends on the extent of the lesion and the degree of pulp involvement. CASE SERIES: This case series reports on four patients with progressive pre-eruptive intra-coronal radiolucency...

MATERIALS AND METHODS: Thirty male Wistar rats were randomly assigned to three groups. Mandibular molar teeth were prepared using a low-speed round bur. In Group I, no material was applied; in Group II, teeth were treated with Ca(OH)2 ; and in Group III, teeth were treated with Propolis extract-Ca(OH)2 , followed by Cention N filling...

When dental pulp is exposed, it must be covered with a biocompatible material to form reparative dentine. The material used, besides being biocompatible, should have an ideal surface structure for the attachment, proliferation and differentiation of dental pulp stem cells. This study aimed to evaluate the porosity of the microstructures of four pulp capping materials using micro-computed tomography (micro-CT). Biodentine, Bioaggregate, TheraCal and Dycal materials were prepared according to the manufacturer's instructions using 2 × 9 mm Teflon molds...

AIMS: This study aimed to investigate the anti-inflammatory and odontoblastic effects of cerium-containing mesoporous bioactive glass nanoparticles (Ce-MBGNs) on dental pulp cells as novel pulp-capping agents. METHODOLOGY: Ce-MBGNs were synthesized using a post-impregnation strategy based on the antioxidant properties of Ce ions and proposed the first use of Ce-MBGNs for pulp-capping application. The biocompatibility of Ce-MBGNs was analysed using the CCK-8 assay and apoptosis detection...

The preservation of vital pulps is crucial for maintaining the physiological functions of teeth; however, vital pulp therapy (VPT) of pulpitis teeth remains a substantial challenge due to uncontrolled infection, excessive inflammation, and limited regenerative potential. Current pulp capping agents have restricted effects in the infectious and inflammatory microenvironment. To address this, a multifunctional hydrogel (TGH/DM) with antibacterial, immunomodulatory, and mineralization-promoting effects was designed...

Deep caries occurs when caries progresses to the deep dentin layer, and further progression has the risk of pulp exposure, which may affect pulp vitality and tooth longevity. Currently, there are no objective standards for the diagnosis of deep caries. In addition, traditional therapy for deep caries emphasizes complete debridement of the decayed tissue, resulting in an incremental high risk of pulp exposure. There are different views on how to deal with the remaining dentin after caries removal, and root canal treatment is often adopted directly after pulp exposure...
