AIM To compare long-term effects of brushing with an oscillating-rotating power toothbrush or an ADA reference manual toothbrush on pre-existing gingival recession. MATERIALS AND METHODS In this controlled, prospective, single-blind, parallel-group study, healthy subjects with pre-existing recession were randomized and brushed with a power toothbrush (n = 55) or an ADA reference manual toothb...

Statement of problem: One of the main goals in periodontal therapy is the correction of recession defects; therefore the efficacy and predictability of the various techniques are important considerations for clinicians. Purpose: The purpose of this pilot study was to compare the outcomes of gingival recession therapy using the semilunar coronally repositioned flap (SCRF) alone and in conjunctio...

This study evaluated the clinical, radiographic, and histologic response to Bio-Oss porous bone mineral when used alone or in combination with Bio-Gide bilayer collagen membrane in human periodontal defects. Four intrabony periodontal defects were treated: two received Bio-Oss alone and two were treated with a combination of Bio-Oss and Bio-Gide. Radiographs, clinical probing depths and attachm...

OBJECTIVE To determine periodontal health status among drug addicts in Jeddah, Kingdom of Saudi Arabia. METHODS Drug addiction recovery patients were recruited from Al-Amal Rehabilitation Hospital, Jeddah, Kingdom of Saudi Arabia between October and December 2012. A questionnaire was used to determine socio-demographic data, oral hygiene measures, and previous drug abuse. Full periodontal cha...

Background Hyaluronan is a critical component of the extracellular matrix and contributes significantly to tissue hydrodynamics and cell migration and proliferation. Studies have demonstrated its anti-inflammatory, antibacterial, and regenerative effects. The present study aimed to assess the clinical effects of the subgingival application of 0.8% hyaluronic acid gel as an adjunct to scaling an...

OBJECTIVES The aim of the present study was to evaluate the efficacy of autogenous bone graft (ABG) and nano-crystalline hydroxyapatite (Ostim) in the management of human intrabony periodontal defects. STUDY DESIGN Twenty-four similar two and three wall intrabony periodontal defects with ≥5 mm probing depths and ≥3 mm depths of intrabony component in 12 healthy patients were selected. One def...

Polarization gating is a popular technique in biomedical optics. It is widely used to inspect the surface of the tissues (under colinear or cocircular detection) or instead to probe the volume (cross-linear detection), without information on the probed depth. Elliptical polarization is introduced to explore the possibility of probing diffuse tissues at selective depths. A thorough Monte Carlo s...

Nanoindentation became a versatile tool for testing local mechanical properties beyond hardness and modulus. By adapting standard nanoindentation test methods, simple protocols capable of probing thermally activated deformation processes can be accomplished. Abrupt strain-rate changes within one indentation allow determining the strain-rate dependency of hardness at various indentation depths. ...

The Z-Scan (ZS) technique in the thermal regime has been used to measure the nonlinear optical response of low-density lipoprotein (LDL). The ZS technique is carried out in LDL from 40 patients with chronic periodontitis before and after three, six, and 12 months of periodontal treatment. Clinical parameters such as probing depths, bleeding on probing, total and differential white blood cells c...

Materials and Methods: 28 CP and 17 GAgP patients were included in the study and their cigarette consumption was determined by verbal questioning. In each patient, 4 sites with pocket depths of 5mm or greater were selected. At each site the modified gingival index (MGI), plaque index (PlI), bleeding on probing (PD), suppuration (Supp), probing depth (PD) and relative attachment level (RAL) were...
