ObjectivesThis study examined the effects of plasma-rich growth factors (PRGF) on accelerating bone regeneration/repair in fresh extraction sockets, and determined the quality and quantity of bone by assessing the bone density using cone-beam computed tomography (CBCT).Materials and MethodsTwenty patients, who had undergone bilateral extractions, were included in this study. In one extraction socket, PRGF was used and covered with an autologous fibrin plug. Nothing was used in the opposite side extraction socket. Thirteen weeks post extraction, the level of bone regeneration was evaluated on both sides with CBCT.ResultsAt the end of the study, the mean bone density according to the Hounsfield units (HU) in the control group and PRGF group was 500.05 HU (type III bone type) and 647.95 HU (type II bone type), respectively.ConclusionThis study recommends the use of PRGF in post extraction sites to accelerate the rate of bone regeneration and improve the quality of regenerated bone. The technique to process PRGF was simple compared to previously mentioned techniques used for platelet-rich plasma (PRP) preparation. PRP preparation requires a two-cycle centrifugation procedure, leading to a longer processing time.
Objectives
The objective of this study was to highlight the role of lateral arthroplasty along with interposition of the buccal fat pad (BFP) in the management of Sawhney type III temporomandibular joint (TMJ) ankylosis.
Materials and Methods
Ten patients with TMJ ankylosis (7 unilateral and 3 bilateral, total of 13 joints) were treated with lateral arthroplasty and BFP interposition. The bony bridge of the ankylotic mass on the lateral aspect was resected, leaving a distance of 1.5 to 2.0 cm from the base of the skull to the neck of the condyle. The condyle was left intact. Coronoidectomy was performed on the ipsilateral side via the same approach in all cases. The inter-incisal opening was measured at that time, and if it was less than 35 mm, contralateral coronoidectomy was performed by using the intra-oral approach. After satisfactory inter-incisal mouth opening (≥35 mm) was achieved, the TMJ surgical site was revisited, and BFP was retrieved and used to cover the lateral aspect of the medially placed condyle.
Results
With lateral arthroplasty, the medially displaced condyle can be left in-situ to maintain the mandibular ramal height and function and to act as a growth center in children. Interposition of the BFP prevents reformation of the lateral bony bridge that was removed.
Conclusion
Lateral arthroplasty along with interpositioning of the BFP is a novel technique for managing Sawhney type III ankylosis that achieves management goals while avoiding complex and advanced reconstructive surgical procedures.
Painful conditions of unexplained origin pose a challenging task for the clinician from both the diagnosis and treatment perspective. This might be accounted due to overlapping symptomatology; moreover, nonspecific subjective findings push the diagnostic process to a more perplexing direction. The main loophole in their management lies in difficulty to make an appropriate diagnosis. Clicking hyoid is an extremely rare anomaly of hyoid bone which produces painful clicking in throat. Here, we report a case of a young patient presented with pain and clicking in throat which aggravated on swallowing. After a series of examinations, it was diagnosed as clicking hyoid and was managed successfully by surgical treatment. The objective of this article is not only to increase awareness of the ailment so as to validate its existence but also demonstrate the significant utility of the surgical management.
Introduction Despite the availability of wide variety of pharmacological agents for dental procedural sedation, there has always been a continuous search for newer sedative agents. Dexmedetomidine is a newer sedative agent for provision of short-term sedation (\24 h) in adult patients in the intensive care unit setting. It is a selective a 2 adrenergic receptor agonist. The reports on off-label use of this drug in a variety of settings for invasive and non invasive procedural sedation have provided encouraging results. Material and methods The present paper reports a pilot study observing clinical efficacy of the newer drug dexmedetomidine in patients undergoing office based sliding genioplasty for correction of facial asymmetry. Subjects were sedated with dexmedetomidine with a loading dose of 0.5 mcg/kg over 10 min followed by a continuous infusion dose of 0.1 mcg/kg/h, the recovery process was observed for 60 min after the dexmedetomidine infusion was stopped. The patients were observed pre operatively, intra operatively (every 10 min) and postoperatively for the following parameters-oxygen saturation (SpO 2 ), mean arterial pressure (MAP), heart rate (HR), and Ramsay sedation score (RSS), respiratory rate, pain scale.
