Prospective

This prospective interventional in-vitro study was aimed at evaluating the effect of pre-processing treatment of ridge-lap surfaces of acrylic teeth, on the strength of the bond between the teeth and the denture base resin. Three test groups included application of mono-methylmethacrylate, air-abrasion with 110-µm aluminium oxide particles and combination of the two methods. A total of 40 tooth-acrylic resin samples were equally divided into four groups (three test groups and one control group) and shear load testing was carried out in the Universal testing machine. Tukey post-hoc analysis revealed that Group IV had significantly higher mean compressive strength than Group I (*p<0.05). No significant differences were present in any of the group comparisons. There was a significant effect produced on the shear bond strength of the interface only when both MMA application and air-abrasion of the ridge-lap surfaces was carried out. Fracture analysis revealed that most of the specimens showed cohesive failure at the interface with adhesive failure restricted to control group exclusively. Despite reported progress in the development of denture base resins and artificial tooth materials, the bond between acrylic denture teeth and denture base materials remains unreliable, inconsistent and unpredictable. Adhesive bond strength between denture base resin and artificial teeth constitutes one of the most important considerations in the technical procedure related to the fabrication of removable dentures.

To Evaluate the Prescribing Pattern of different types of Chronic Headache in a tertiary Care Hospital. 63 patients were the subjects in Medicine Department of a Multispecialty Hospital, in Greater Noida. It was a duly approved, prospective study, in patients on chronic Headache therapy, conducted by competent professionals. The data was obtained from physicians’ prescribing records and patients by individual interviews using the structured proformas as per World Health Organization guidelines. In 63 patients, suffering from different types of headache were evaluated. Among the 63 patients suffering from headache 17(26.98%) were males and 46(73.01%) were females, indicating 3:1 (Female: male) prevalence ratio of headache. Out of 63 patients of chronic headache, age range of 31-40 years had the maximum number 22(34.92%) of patients, followed by 21(33.33%) in age range of 21-30 year. Among the 63 patients suffering from headache Out of 31 patients diagnosed of migraine headache 23(74.19%) were females and 8(25.86%) were males, indicating prevalence of migraine 3 times more in females than in male. NSAIDs (100%) were the most prescribed abortive treatment followed by ergotamine 22(34.92%) and prochlorperazine 22 (34.92%). Among the opoid analgesics caffeine 22(34.92%) was mostly prescribed followed by tramadol 13(20.63%). Sumatriptan 9(14.28%) was less prescribed. The prospective study demonstrated that the incidence migraine headache was found to be higher in female patients. NSAIDs were the most prescribed abortive treatment followed by ergotamine 22(34.92%) and prochlorperazine22 (34.92%) Among the opoid analgesics caffeine was mostly prescribed followed by tramadol.
