Although corticosteroid provides many clinical benefits, it may cause a range of side effects. A 47-year-old female patient presented with a complaint of pain from her teeth, triggered upon taking cold, hot, and sweet food and drink. From her medical history, she was previously diagnosed with ulcerative colitis. She consequently developed pyoderma gangrenosum, and high-dose prednisolone was administered to treat this condition (prednisolone 30 mg bd for 4 months followed by tapering dose 5 mg/week). She claimed the pain started at the end of steroid therapy...

Background: Posttreatment endodontic pain has been reported in 25%-40% of all endodontic patients. Effective management of endodontic pain represents a continuing challenge. Aim: To evaluate and compare the efficacy of preoperative single dose of nonsteroidal anti-inflammatory drug, piroxicam (20 mg), with two types of corticosteroid drugs - dexamethasone (4 mg) or deflazacort (30 mg) - for the prevention and control of postendodontic pain. Materials and Methods: A total of 132 volunteers selected for nonsurgical root canal therapy were randomly divided into the following four groups ( n = 30 each) according to preoperative medication given: Group 1, piroxicam (20 mg); Group 2, dexamethasone (4 mg); Group 3, deflazacort (30 mg); and Group 4, placebo...

Aim: The aim of the present study was to evaluate the effect of varying durations of intracanal medicament application used in regenerative endodontic treatment on the push out the bond strength of a novel cement-NeoMTA Plus. Materials and Methods: A total of 60 extracted single-rooted maxillary anterior teeth were decoronated. Roots were instrumented uniformly until Peeso Reamer size #5 to simulate open apices. A total of 60 roots were then divided into four groups according to intracanal medicaments used ( n = 15): Group 1: Triple antibiotic paste (TAP); Group 2: Double antibiotic paste (DAP); Group 3: Calcium hydroxide paste (CH); and Group 4 (control): No medicament...

Introduction: The interaction between chlorhexidine (CHX) and sodium hypochlorite (NaOCl) yields a thick precipitate capable of occluding dentinal tubules. Previous studies are unclear as to the above-mentioned precipitate contains para-chloroaniline (PCA) or not. PCA is a known toxic and carcinogenic compound which may lead to methemoglobinemia in humans. Aim: This study aims to evaluate the precipitate formed on combination of different irrigants, weigh the amount of precipitate formed and to analyze the precipitate for PCA by using thin layer chromatography (TLC), high performance liquid chromatography (HPLC), column chromatography (CC), electron spray ionization mass spectrometry (ESI-MS), Ultraviolet (UV), and nuclear magnetic resonance (1H-NMR and C-13 NMR)...

Background: In vivo angiogenesis is normal and vital process in growth and development, wound healing, and formation of granulation tissue wherein new blood vessels form from preexisting vessels as part of revascularization. Platelet-rich products promote wound healing associated with angiogenesis. Biomaterials such as titanium were found to be angiogenic. Unlike in vivo situations, in vitro angiogenesis, study cells, within a controlled environment. Aims: The aim of this study is to evaluate the angiogenic potential of a novel platelet-rich product...
