Histopathological alterations of tissue adjacent DMBA-induced premalignancy following a radiowave diathermy intervension

Leukoplakia like lesion was induced in hamster buccal pouch mucosa utilizing DMBA and subsequently removed using different methods including radiowave diathermy. Histologic changes of the surrounding tissue was examined after 10 weeks period. Although malignant transformation was shown to develop as a result of effect of radiowave diathermy interference, lack of tumor potentiating was recorded

Biochemical study of copper, zinc, calcium, selenium, phosphorus and sulfer in cancer of oral cavity

In patients with malignant tumors of oral cavity, serum, copper, zinc, calcium, phosphorus and sulfur were compared with the same elements of patients without malignant tumors. These elements were significantly higher in patients with malignant tumors than in healthy patients [P>0.001]

Objective evaluation of topical viscous 5% lignocaine jelly on pain during management of dry socket

This study evaluated the efficacy of topical viscous 5% lignocaine jelly for the alleviation of pain experienced during instrumention of mandibular third molar extraction sites diagnosed with dry socket and for pain releif during the post instrumentation period. Thirty adult patient with a diagnosis of dry socket in mandibular third molar extraction site were included in this blind study. All patient had their sutures removed. The socket irritated and 5% lignocaine jelly placed on the tip and side of tongue to blind the patient against the test substances. The subjects were then randomly distributed into two groups: Group I had non-active jelly base placed in to the socket 2 minutes preior to the placement of a standard obtundant dressing. Group 2 had viscous 5% lignocaine jelly placed into the socket in the some mannar. Patients subjectively quantified their pain intensity, before treatment immediately post manipulation, at 5- minute intervals to 30 minutes, and 45 to 60 minutes. They also subjectively quantified their pain relief at each of the time intervals following instrumentation. There was no statistical differences between the pretreatment pain experienced by both groups. The use of lignocaine jelly had a measurable [P>0.05] but was not statistically significant. At every time interval, the use of 5% lignocaine jelly showed a statistically significant [P<0.05] decrease in pain preception and a statistically significant increase in pain relief when compared with the active jelly

Blood loss after dental extraction in patient on anticoagulant therapy

This study was performed to assess the extent of bleeding in patients on anticoagulant therapy undergoing extraction of lower molars when compared with normal individuals. Patients on anticoagulant medication undergoing dental extraction of lower molars either stopped their anticoagulant rigimen 72 to 96 hours before the extraction or continued their regular regimen through the time of extraction. Blood loss was measured by weighting sponges used in the procedures. They were compared with an additional control group that had never been on anticoagulant therapy. There was no difference in blood loss detected among any experimental or control group. No bleeding complications occurred in any anticoagulant patients
