Long term effect of panretinal photocoagulation on retinal nerve fiber layer parameters in patients with proliferative diabetic retinopathy.

Purpose: This study aimed to evaluate the long-term effect of panretinal photocoagulation (PRP) on the retinal nerve fiber layer (RNFL) in patients with proliferative diabetic retinopathy (PDR).

Methods: This was a prospective longitudinal cohort study examining 42 eyes of 42 patients with PDR undergoing PRP. Peripapillary RNFL thickness (RNFLT) was measured using spectral-domain optical coherence tomography at baseline, 1 year, and 3 years following PRP.

Evaluation of peri-implant soft tissue and bone levels around early loaded implant in restoring single missing tooth: A clinico-radiographic study.

Background: One-stage nonsubmerged protocol which can achieve success rates comparable to implants placed in a two-staged submerged procedure also the preconditions for periimplant bone regeneration has lead to more refined concepts of implant loading.

Materials And Methods: Twenty sites with single missing tooth were included in this study. Clinical parameters included sulcus bleeding index (sBI), probing pocket depth (PD), and papilla index (PI) and radiographic parameters included crestal bone level were assessed for a period of 9 months.

Evaluation of efficacy of tetracycline fibers in conjunction with scaling and root planing in patients with chronic periodontitis.

Aim: The objective of this study was to compare the efficacy of scaling and root planing (SRP) alone versus tetracycline fiber therapy used adjunctively with SRP in the treatment of chronic periodontitis sites in maintenance patients.

Materials And Methods: A total of 30 patients with a diagnosis of chronic periodontitis (60 localized chronic periodontitis sites) in the age group of 35 to 55 were selected. None of these patients had received any surgical or non-surgical periodontal therapy and had sites of periodontal pockets measuring 4-7 mm clinically and demonstrated radiographic evidence of moderate bone loss.

The effect of menstrual cycle on periodontal health - a clinical and microbiological study.

Purpose: Fluctuations in female sex hormones result in changes in the gingival and periodontal tissues. The purpose of this study was to compare the periodontal status of premenopausal women at different time points during their menstrual cycle and to find the associated subgingival microbiota.

Materials And Methods: One hundred premenopausal women participated in the study and were divided into two groups: group I consisted of 50 subjects with clinically healthy gingival, and group II consisted of 50 subjects with chronic gingivitis.
