RESUMEN
PURPOSE: This study is an attempt to evaluate the use of autologous platelet rich plasma (PRP) to promote wound healing and osseous regeneration in human third molar extraction sockets. MATERIALS AND METHOD: PRP was prepared after two centrifugation and the gelling agent used was freshly prepared 10% calcium chloride.PRP gel was placed in one of the extracted sockets of bilateral impacted mandibular third molars. IOPA Xrays were used to evaluate the wound dehiscence, probing depth, bone density & alveolar bone level after 1st, 2nd and 7th day and 3rd & 6th month respectively. RESULTS: On evaluation, it was found that PRP grafted sockets showed dehiscence in 8% cases. The decrease in alveolar bone level was highly significant in PRP grafted sockets in 3rd and 6th month post operatively. There was significant difference between pre-operative density of adjacent bone and bone formed in extraction sockets at 3rd and 6th month in PRP grafted sockets. There was significant reduction in probing depth from initial period to 3 and 6 months in both the groups, but PRP grafted sockets showed greater decrease in probing depth. CONCLUSION: PRP is an inexpensive and widely available modality to minimize postoperative complication and enhance both hard and soft tissue healing potentials. This autologous product eliminates concern about immunogenic reaction and disease transmission. Its beneficial outcomes in dental clinic, including decrease in bleeding and rapid wound healing hold promise for further procedures.PRP is thus a new application in tissue engineering and developing area for clinician and researchers.
RESUMEN
Myositis ossificans (MO), as its name implies, is ossification and bone formation within a muscle. Pathogenesis is not all clear, but trauma is universally recognized as a trigger event. Myositis ossificans can be divided into 2 classifications: MO progressiva and MO traumatica. When it affects the muscles of mastication, it causes severe trismus. This rare disorder and its limited treatment options can potentially have debilitating effects to the patient's normal oral functioning and health. A computed tomographic scan and panoramic radiographs are essential diagnostic aids for evaluating conditions such as MO. Myositis ossificans can be one of the causes of extra-articular temporomandibular joint ankylosis. Surgical excision of the ossification is the main treatment modality. This is a case report of a patient who developed MO of the muscles of mastication.

The odontogenic keratocyst is a very well known odontogenic cyst. There are many types of cysts of the jaws, but what makes the odontogenic keratocyst unusual are its characteristic histopathological and clinical features, including potentially aggressive behaviour, high recurrence rate, and an association with the nevoid basal cell carcinoma syndrome. The characteristic histologic feature i.e. the presence of parakeratin, is unique amongst all the different inflammatory and developmental cysts that occur in the jaws. Many treatment modalities have been advocated for its treatment, but none in particular has been regarded as the best treatment option. The 2005 WHO classification now uses the term 'keratocystic odontogenic tumor'. We present a review of treatment modalities of the KCOT.
