Pain, swelling, and trismus are known sequelae of third molar surgery that can significantly affect the individual's quality of life (QOL). These should be minimized to improve QOL. The purpose of this study was to compare the effects of the preoperative submucosal administration of equivalent doses of two commonly used steroids on these postoperative sequelae. A randomized controlled clinical trial was conducted involving 60 subjects requiring the removal of impacted mandibular third molars. Extraction cases with a similar difficulty index were included...

BACKGROUND: The odontogenic cystic lesions happened in the angle and ramus region are frequently associated with impacted mandibular third molars. The treatment plan was difficult to work out for the huge cystic lesions with deeply impacted third molars, since the enucleation with simultaneously removing the deeply impacted teeth may cause serious complications. Therefore, the marsupialization of the cystic lesions followed by enucleation with tooth removal has also been advocated. The aim of this study was to explore the movement of cystic lesion-associated deeply impacted mandibular third molars (IMTM) after marsupialization...

Dental pulp stem cells (DPSCs) have been proposed as a promising source of stem cells in nerve regeneration due to their close embryonic origin and ease of harvest. Resveratrol (RSV) is a natural polyphenolic and possesses many biological functions such as anti-inflammatory activity and protection against atherosclerosis and neuroprotective activities. There is increasing evidence showing that RSV plays a pivotal role in neuron protection and neuronal differentiation. In this study, we isolated DPSCs from impacted third molars and investigated whether RSV induces neuronal differentiation of DPSCs...

Clinical use of zoledronate is accompanied with osteonecrosis of the jaw but the pathogenesis is not well understood. We assumed that zoledronate may have cytotoxicity against stem cells of the oral cavity, and in this way helps to initiate or promoting osteonecrosis. Dental pulp stem cells (DPSCs) and gingival fibroblasts (GFs) were isolated from volunteers who were undergoing third molar extraction. The proliferation of DPSCs and GFs was evaluated using thiazolyl blue tetrazolium bromide assay. Effect of zoledronate on apoptosis was determined by propidium iodide staining and western blotting analysis...

Third molar extraction is one of the most frequent interventions in dentistry. Nevertheless, there is scarce evidence on the host response of individuals with impacted or semi-impacted third molars and the possible effects of surgical removal. A case-control study of 40 patients was designed to evaluate 1) the differences in biomarkers of systemic inflammation, vascular function, and metabolism (high-sensitive C-reactive protein, lipids, fibrinogen, oxidative stress, and endothelial function analysis) and 2) the acute and short-term effects of surgical removal in patients with bilateral impacted or semi-impacted third molars compared to controls with no third molars...

Trauma to the adjacent hard and soft tissue is the most common iatrogenic injury during extraction of the mandibular third molar. As every functional component of the dental arch is of prime importance in contemporary dental practice, the major concern must be in conserving the tooth and its structure as much as possible. The present case discusses the application of this conservative approach for management of iatrogenically damaged distal root of the mandibular second molar during extraction of impacted third molar, in which excessive guttering of alveolar bone and fractured apical third of distal root of 37 was observed radiographically...

OBJECTIVE: The objective of the study was to determine the potential risk of tooth/root displacement into the soft tissue during the third molar surgery. While performing third molar surgeries, one of the many complications is displacement of the tooth into the soft tissues. This can be due perforation of the lingual cortical bone during surgery or the position of the tooth root which may be close to the lingual bone. MATERIALS AND METHODS: Retrospective samples of 251 patients were collected who had undergone cone-beam computed tomography (CBCT) for various reasons...

Cerebrospinal fluid (CSF) contains several molecules which are essential for neurogenesis. Human dental pulp stem cells (hDPSCs) are putatively neural crest cell-derived that can differentiate into neurons and glial cells under appropriate neurotrophic factors. The aim of this study was to induce differentiation of hDPSCs into neuroglial phenotypes using retinoic acid (RA) and CSF. The hDPSCs from an impacted third molar were isolated by mechanical and digestion and cultured. The cells have treated by 10(-7) µM RA (RA group) for 8 days, 10% CSF (CSF group) for 8 days and RA with CSF for 8 days (RA/CSF group)...
