Platelet-Rich Fibrin Combined With a Porous Hydroxyapatite Graft for the Treatment of 3-Wall Intrabony Defects in Chronic Periodontitis: A Randomized Controlled Clinical Trial.

Background: Porous hydroxyapatite (HA) bone grafting material has been used to fill periodontal intrabony defects (IBDs), resulting in clinically acceptable responses. Platelet-rich fibrin (PRF) is a leukocyte and platelet preparation that concentrates various polypeptide growth factors and, therefore, has the potential for use as regenerative treatment for periodontal defects. The present study aims to explore the clinical and radiographic effectiveness of autologous PRF versus PRF + HA in treatment of IBDs in patients with chronic periodontitis.

Pediatric cataract.

Pediatric cataract is a leading cause of childhood blindness. Untreated cataracts in children lead to tremendous social, economical, and emotional burden to the child, family, and society. Blindness related to pediatric cataract can be treated with early identification and appropriate management.

Pediatric Cataract - Importance of Early Detection and Management.

Pediatric cataract is often diagnosed and managed late. This delay may be due to the ignorance on the part of the community, financial constraints, delay in the diagnosis and lack of tertiary care facilities. There is an urgent need to include rubella vaccination in the universal immunization program.

Aim: The aim of this study was to evaluate specular microscopy of chronic primary angle-closure glaucoma (CPACG) eyes at least 1 year after Nd:YAG iridotomy, and compare them with CPACG eyes without an iridotomy and age-matched, normal eyes.

Patients And Method: Consecutive patients of CPACG at the Glaucoma service were screened. All patients underwent slit-lamp biomicroscopy, +90 D examination, and applanation tonometry.

Innovations in pediatric cataract surgery.

Advances in technology have made surgery in children safer and faster. The management of pediatric cataract has made rapid progress in the past decade with the availability of safer anesthesia, newer technique's, more predictable intraocular lens (IOL) power calculation, a better understanding of neurobiology, genetics, amblyopia management, improved IOL designs for preventing visual axis opacification, and adjuvant postoperative care. Modern vitrectomy machines with minimally invasive instruments, radiofrequency, diathermy, and plasma blades help immensely in complicated cases.

It has a variety of applications ranging from minor surgical procedures to complex implantology, plastic and reconstructive surgeries.

4-Hydroxy-2-nonenal, an oxidative stress marker in crevicular fluid and serum in type 2 diabetes with chronic periodontitis.

Objective: Chronic periodontitis (CP) is a common, chronic inflammatory disease initiated by bacteria, which has an increased prevalence and severity in patients with type 2 diabetes mellitus (t2 DM). A variety of reactive oxygen species are able to cause direct damage to proteins, deoxyribonucleic acid, carbohydrates and lipids. Lipid peroxidation is always combined with the formation of reactive aldehydes like 4-Hydroxy-2-nonenal (HNE).

Protein carbonyl: An oxidative stress marker in gingival crevicular fluid in healthy, gingivitis, and chronic periodontitis subjects.

Background: A defined role for reactive oxygen species (ROS) in the tissue destruction that characterizes periodontitis has been described. Protein carbonyl (PC) is the most widely used biomarker for oxidative damage to proteins, and reflects cellular damage induced by multiple forms of ROS. The purpose of this study is to determine the presence of PC in gingival crevicular fluid (GCF) in healthy, gingivitis, and chronic periodontitis (CP) subjects and to find an association, if any.

8-Isoprostane: a lipid peroxidation product in gingival crevicular fluid in healthy, gingivitis and chronic periodontitis subjects.

Objective: The idea that reactive oxygen species (ROS) are associated with the pathogenesis of inflammatory periodontal diseases and have a role (direct or indirect) in tissue damage has become a major area of research over the last decade. The purpose of this study is to determine, presence of 8-isoprostane in gingival crevicular fluid (GCF) in healthy, gingivitis and chronic periodontitis (CP) subjects and to find an association, if any between GCF 8-isoprostane levels and clinical periodontal parameters.

Materials And Methods: 78 subjects (40 males and 38 females) were selected based on their clinical parameters into three groups: Group 1 (26 healthy), Group 2 (26 gingivitis subjects) and Group 3 (26 CP subjects).

The present study aimed to explore the clinical and radiographical effectiveness of autologous platelet-rich fibrin (PRF) and autologous platelet-rich plasma (PRP) in the treatment of mandibular degree II furcation defects in subjects with chronic periodontitis.

Clinical and microbiological effects of commercially available dentifrice containing amine fluoride: A randomized controlled clinical trial.

Background: The inability of the normal adult population to perform adequate tooth brushing has led to the search for chemotherapeutic agents in order to improve plaque control. This 6 month, single center, randomized controlled clinical trial was conducted to assess the clinical and microbiological effects of a dentifrice containing only amine fluoride (AF) as the active ingredient on gingivitis.

Materials And Methods: NINETY SUBJECTS DIAGNOSED WITH CHRONIC GENERALIZED GINGIVITIS WERE SELECTED AND RANDOMLY DIVIDED IN THREE GROUPS: Group 1 - placebo toothpaste, Group 2 - AF containing toothpaste, and Group 3 - triclosan containing toothpaste with polymer and fluoride.
