Pleomorphic adenoma is a common benign salivary gland tumor which presents as a painless swelling that gradually increases in size, if left untreated. It is often seen involving the parotid gland. However, pleomorphic adenoma has been reported to involve the minor salivary glands as well. In this report, we present two cases of pleomorphic adenoma originating from minor salivary glands of the upper lip, occurring in two male patients of the same age (44 years) with markedly similar history of duration, size, and site of the lesion. The tumor was excised in both patients and sent for histopathological analysis which showed features of pleomorphic adenoma confirming the diagnosis.

Aims:To compare the efficacy of Platelet rich plasma and synthetic graft material for bone regeneration after bilateral third molar extraction.Material and Methods:This study was conducted in 10 patients visiting the outpatient department of Oral & Maxillofacial Surgery, Yenepoya Dental College & Hospital. Patients requiring extraction of bilateral mandibular third molars were taken for the study. Following extraction, PRP (Platelet Rich Plasma) was placed in one extraction socket and synthetic graft material in form granules [combination of Hydroxyapatite (HA) and Bioactive glass (BG)] in another extraction socket. The patients were assessed for postoperative pain and soft tissue healing. Radiological assessment of the extraction site was done at 8, 12 and 16 weeks interval to compare the change in bone density in both the sockets.Results:Pain was less on PRP site when compared to HA site. Soft tissue evaluation done using gingival healing index given by Landry et al showed better healing on PRP site when compared to HA site. The evaluation of bone density by radiological assessment showed the grey level values calculated at 4 months at the PRP site were comparatively higher than HA site.Conclusion:The study showed that the platelet rich plasma is a better graft material than synthetic graft material in terms of soft tissue and bone healing. However a more elaborate study with a larger number of clinical cases is very much essential to be more conclusive regarding the efficacy of both the materials.

Background The term temporomandibular joint internal derangement has characteristic clinical findings such as restricted mouth opening, pain, irregular deviated jaw function and clicking sounds. The technique of TMJ arthrocentesis has gained widespread acceptance as a simple and effective technique for the treatment of acute persistent closed lock of the TMJ. Arthrocentesis is known as the lavage and lysis of upper joint compartment. Purpose To evaluate the efficacy of sodium hyaluronate followed by single-puncture arthrocentesis. Sodium hyaluronate is the sodium salt of hyaluronic acid which is a polysaccharide of the glycosaminoglycans family, found in many extracellular tissues, including synovial fluid and cartilage. Exogenous hyaluronate can stimulate the synthesis of endogenous hyaluronic acid. Methods In our study, a sample of 10 patients (7 females and 3 males) with TMJ disorder was selected. Arthrocentesis was done followed by sodium hyaluronate injection for all the patients. Results On follow-up ranging from 1 to 3 months, pain at rest and pain on mastication had substantially decreased in all patients and mandibular function and mouth opening had significantly improved. Conclusion Our study shows that single-puncture Ringer's lactate arthrocentesis followed by sodium hyaluronate injection is effective in the management of the internal derangement of the temporomandibular joint.

Atropine sulphate and glycopyrrolate were equally potent as an antisialogogue. There was a significant increase in heart rate 30 min after the administration of atropine sulphate, but there was no significant change in heart rate in glycopyrrolate group. Conclusion Intramuscular gycopyrrolate is safer than intramuscular atropine sulphate as an antisialogogue in minor oral surgical procedures under local anesthesia.
