Effects of Thai propolis mixed in mineral trioxide aggregate on matrix metalloproteinase-2 expression and activity in inflamed human dental pulp cells.

Objectives: This study sought to determine effects of Thai propolis extract mixed in mineral trioxide aggregate (MTA) on matrix metalloproteinase-2 (MMP-2) expression and its activity in inflamed human dental pulp cells (HDPCs).

Materials And Methods: Interleukin-1β-primed HDPCs were treated with either the eluate of MTA mixed with distilled water, of MTA mixed with 0.75 mg/ml of the propolis extract, or of Dycal®, 0.

Atomoxetine and escitalopram migrate the derangement of the temporomandibular joint morphologic and histologic changes in rats exposed to stress-induced depression.

Purpose: The purpose of this in vivo study was to determine the effects of stress-induced depression and antidepressants on depressive-like behavior, microstructure, and histomorphology of the temporomandibular joint (TMJ) using rats.

Methods: Experimentally induced depression in rats was created before being treated with two antidepressants; escitalopram (selective-serotonin-reuptake inhibitors) and atomoxetine (norepinephrine-reuptake inhibitors). Micro-computed tomography (Micro-CT) was performed to measure the change in bone volume and bone porosity of the condyle.

An in vitro anti-inflammatory effect of Thai propolis in human dental pulp cells.

Objective: To explore the potential for development of Thai propolis extract as a pulp capping agent to suppress pulpal inflammation from dental pulp infections. This study aimed to examine the anti-inflammatory effect of the propolis extract on the arachidonic acid pathway, activated by interleukin (IL)-1β, in cultured human dental pulp cells.

Methodology: Dental pulp cells, isolated from three freshly extracted third molars, were first characterized for their mesenchymal origin and treated with 10 ng/ml of IL-1β in the presence or absence of non-toxic concentrations of the extract from 0.

Preservation of the viability and gene expression of human periodontal ligament cells by Thai propolis extract.

Background/aim: Success of tooth replantation depends on the quality and quantity of periodontal ligament (PDL) cells. The aims of this study were to evaluate Thai propolis extract as a storage medium for maintaining PDL cell viability and preserving gene expressions in PDL tissues.

Materials And Methods: PDL cells from human premolars were tested for cytotoxicity of the extract by PrestoBlue assay to determine a non-toxic concentration.

Promotion of Dental Pulp Wound Healing in New Zealand White Rabbits' Teeth by Thai Propolis Product.

This study examined and compared wound healing between Thai propolis product and calcium hydroxide paste as pulp-capping agents after partial pulpotomy in New Zealand white rabbits. Forty incisor teeth from 10 rabbits were treated. Thirty-six teeth received class V cavity preparations with partial pulpotomy and application of either propolis or calcium hydroxide paste.

Inhibitory effect of Thai propolis on human osteoclastogenesis.

Background/aim: Avulsed teeth should be immediately replanted into the socket or otherwise kept in a physiologic storage medium to maintain periodontal ligament cell viability. A previous study has demonstrated that Thai propolis extract can maintain viability of human periodontal ligament cells. However, root resorption by osteoclasts often occurs when the avulsed teeth are replanted.

Supplementary techniques for pain control during root canal treatment of lower posterior teeth with irreversible pulpitis: A systematic review and meta-analysis.

The purpose of this systematic review and meta-analysis was to evaluate utilisation of supplementary techniques for pain control during root canal treatment of lower molars with irreversible pulpitis. The literature was searched using electronic databases up to year 2012. Seventeen studies with 1504 participants were included and each study compared experimental interventions with a standard treatment, i.

The preservative effect of Thai propolis extract on the viability of human periodontal ligament cells.

Background/aim: Tooth avulsion causes an injury to the periodontal ligament (PDL). The success of tooth replantation depends on the quantity and quality of PDL cells. The aim of this study was to examine the preservative and proliferative effects of Thai propolis extract, previously shown to exert anti-inflammatory and antioxidant activities, on human PDL cells.

Decoronation as a treatment option for replacement root resorption following severe intrusive trauma: a case report.

This article reports a clinical case of a 13-year-old girl, who was referred with chief complaint of a non-esthetic maxillary central incisors position. Five years ago, her maxillary right and left central incisors and left lateral incisor intruded into the maxilla. The intruded teeth were splinted for a month.

Bacterial and dye penetration through interim restorations used during endodontic treatment of molar teeth.

Introduction: The purpose of this study was to investigate the association between dye and bacterial penetration through interim restorations used during endodontic treatment.

Methods: Sixty-four extracted human teeth were used, with 2 teeth each as positive and negative controls. Endodontic access with a mesio-occluso-distal cavity was prepared.
