RESUMO
Objective: To compare postoperative sensitivity following composite restoration placed in supra gingival class-V cavities using self etch adhesive and total etch adhesive. Study Design: A randomized clinical trial. Place and Duration of Study: Operative Dentistry Department of Armed Forces Institute of Dentistry, Rawalpindi, from July to December 2009
Methodology: A total of 70 patients having class-V supra gingival carious lesions were divided into two groups. Classes-V cavities not exceeding 3 mm were prepared. One treatment group was treated with self etch adhesive [adhe SE one Ivoclar] and the control group was treated with total-etch adhesive [Eco-Etch Ivoclar] after acid etching with 37% phosphoric acid. Light cured composite [Te-Econom Ivoclar] restoration was placed for both groups and evaluated for postoperative sensitivity immediately after restoration, after 24 hours and after one week. Data was recorded on visual analogue scale
Results: Comparison of sensitivity between the two treatment groups on application cold stimulus after 24 hours of restoration showed significant difference; however, no statistically significant difference was observed at baseline, immediately after restoration and at 1 week follow-up with cold stimulus or compressed air application
Conclusion: Less postoperative sensitivity was observed at postoperative 24 hours assessment in restoration placed using SE adhesives compared to TE adhesives. Thus, the use of SE adhesives may be helpful in reducing postoperative sensitivity during 24 hours after restoration placement
RESUMO
To determine diagnostic accuracy [in terms of sensitivity, specificity, positive predictive value and negative predictive value] of electrocardiography for left ventricular hypertrophy [LVH]. Cross sectional validation type. Pakistan Institute of Medical Sciences [PIMS] from 1 January 2013 to 30 June 2013. A cross-sectional study was conducted at department of cardiology. Two hundred and fifty hypertensive patients, both male and female were included in the study. The data was collected by non-probability, purposive sampling. A performa was filled indicating their bio-data, history and clinical examination. All the patients were then subjected to 12 lead electrocardiogram [ECG] and echocardiography to detect LVH. Sokolow Lyon product index and Cornell product index was calculated on ECG to detect LVH. Data was analysed using SPSS 11. Out of 250 hypertensive patients, a total of 110 [44%] patients had LVH by echocardiography Out of these 110 patients, 60 [54.5%] patients had both positive Sokolow Lyon and Cornell product indices and 50 [45.5%] had negative both Sokolow Lyon and Cornell product indices. The calculated sensitivity, specificity, positive predictive value, negative predictive value and overall diagnostic accuracy of combined Sokolow Lyon and Cornell product indices were 54.5%, 97.9%, 95.2%, 73.3% and 78.8% respectively. The ECG criteria of combined Sokolow Lyon and Cornell product indices had a high specificity and PPV for the detection of left ventricular hypertrophy using echocardiography as a gold standard. However ECG has low sensitivity and NPV for LVH and hence is not a reliable screening tool for detection of LVH
