ABSTRACT
Background: To assess effect and safety of beta blockers in hypertensive patients.Material & Methods:One hundred twelve adult patients who were diagnosed cases of hypertension of either gender were divided into 2 groups. Each group contained 56 patients. Group I received 25 mg atenolol twice daily and group II received 25 mg metoprolol tartrate twice daily. History of diabetes, kidney disease, lipid disorder, incident cardiovascular (CV) events etc. was recorded. Blood pressure (systolic and diastolic) was recorded before starting and after starting the drug therapy.Results:Age group 20-40 years had 12 in group I and 11 in group II, 41-60 years had 14 in group I and 17 in group II and >60 years had 30 in group I and 28 in group II. There were 40 males and 16 females in group I and 38 males and 18 females in group II. A significant difference in males and females within the group (P< 0.05) and non- significant intergroup difference was observed (P> 0.05). The mean SBP found to be 149.4 mm Hg in group I and 146.7 mm Hg in group II and DBP was 85.4 mm Hg in group I and 83.6 mm Hg in group II at baseline and SBP was 135.4 mm Hg in group I and 134.6 mm Hg in group II and 78.2 mm Hg in group I and 78.0 mm Hg in group II at 6 months. Diabetes mellitus was seen in 12 in group I and 19 in group II, lipid disorders 17 in group I and 28 in group II, chronic kidney disease 11 in group I and 16 in group II and CV event 2 in group I and 4 in group II. Conclusions:Both beta blockers found to be equally effective in management of patients with hypertension.
ABSTRACT
Context: Both intraoral autogenous bone grafting (ABG) and platelet-rich fibrin (PRF) offer a useful treatment modality for periodontal regeneration of intrabony defects (IBDs). However, predictable regeneration in patients with severe attachment loss is a challenge to the practitioners. Aim: The aim of this study was to compare the clinical efficacy of PRF with ABG for the treatment of IBDs in chronic periodontitis. Settings and Design: This is a randomized controlled trial. Materials and Methods: Twenty chronic periodontitis patients with IBDs were randomly treated by PRF or ABG. Probing pocket depth (PPD), relative attachment level (RAL), surgical reentry bone fill, and radiographic bone fill (RBF) were recorded at baseline, 3, 6, and 9 months postsurgery, respectively. Statistical Analysis: Student's t-test was used for continuous variables. All means were expressed as mean ± standard deviation and proportions were expressed in percentage. The level of significance was set at P < 0.05. Results: Both PRF and ABG sites produced a significant improvement from baseline to 9 months for all the parameters. However, there was no significant difference between the two treatment modalities in the reduction of PPD and RAL gain at 9 months. In addition, ABG showed significantly greater RBF (30.34%) as compared to PRF (20.22%). Similar findings were supported by surgical reentry, where a surgical reentry of 65.31% at ABG sites and 43.64% at PRF sites was seen. Conclusion: Both ABG and PRF can be used predictably to reconstruct lost periodontal structures as indicated by PPD reduction and RAL gain. However, in terms of osseous defect fill, ABG yields more definitive outcome than PRF.
ABSTRACT
Objectives: The purpose of this study was to compare the effect of pre-etching with 37% orthophosphoric acid on the shear bond strength (SBS) of orthodontic brackets bonded using self-etching primer (SEP). Materials and Methods: Two hundred freshly extracted human premolars were divided randomly into two groups based on pre-etching with 37% orthophosphoric acid: Group 1 (control, n = 50) without pre-etching and Group 2 (experimental, n = 150) with pre-etching. Group 2 was further divided into three sub groups 2a, 2b, and 2c with 50 teeth each and was first pre-etched with 37% orthophosphoric acid for 10, 30, and 60 s, respectively. Brackets were bonded on the teeth in both the groups using SEP and light cure adhesive. The SBS were determined using universal testing machine. The comparison of SBS was done using one-way analysis of variance and Tukey's honest significant difference test. Results: The SBS of experimental Group 2 was significantly higher than the control Group 1 (p < 0.0001). Further, the SBS of Group 2a was highest, followed by Group 2b and 2c (p < 0.0001). Conclusion: It was found that pre-etching for 10 s prior to application of SEP-adhesive system increases the SBS of orthodontic brackets.
