Photobiomodulation Therapy by 820 nm Diode Laser on Nonsurgical Periodontal Treatment of Smoker and Nonsmoker Patients: A Single-Blind Parallel Randomized Clinical Trial.

The effect of smoking on nonsurgical periodontal treatment (SRP) is known, but the adjunct use of photobiomodulation (PBMT) to SRP has not been fully investigated in smokers. This study aimed to assess the effect of 820 nm diode laser on SRP in smoker/nonsmoker. Sixty patients (smokers/n = 30, nonsmokers/n = 30) were enrolled in this parallel-arm clinical study.

Humic Acid, a Polyphenolic Substance, Decreases Alveolar Bone Loss in Experimental Periodontitis in Rats.

The purpose of this study was to evaluate the biochemical, morphometric, and histopathological changes associated with experimental periodontitis in rats in response to local administration of humic acid. Thirty-eight Wistar rats were divided into 5 experimental groups: nonligated (NL) group, ligature-only (LO) group, and ligature + local administration of humic acid (20, 80, and 150 mg/kg body weight per day for 15 days, respectively; L-20, L-80, and L-150 groups). Changes in alveolar bone levels were clinically measured as the distance from the cementoenamel junction to the alveolar bone crest with a stereomicroscope.

Effects of Curcumin on Alveolar Bone Loss in Experimental Periodontitis in Rats: A Morphometric and Histopathologic Study.

Curcumin is found in the rhizomes of the turmeric plant that has been showed antioxidant and anti-inflammatory effect. The aim of this study was to evaluate the effects of systemic curcumin therapy on alveolar bone loss in an experimental periodontitis model in rats. Material and Methods: Thirty-two male Wistar rats were randomly divided to 4 groups: 75 mg/kg/daily curcumin (C75; 8), 150 mg/kg/daily curcumin (C150; 8), Control (8), and Ligated (8).

Humic Acid Enhances Wound Healing in the Rat Palate.

Introduction: Humic acid was previously shown to enhance cutaneous wound healing and show antibacterial properties; however, it has not been used for wound healing in the oral cavity. Thus, the goal of this study was the evaluation of the effect of the humic acid on the healing of excisional wounds in an experimental rat study.

Materials And Methods: A circular wound on mid-palatal surfaces was made on a total of 77 Wistar rats by using a 3-mm biopsy punch under anesthesia.

Investigating the Effects of Systemically Administered Strontium Ranelate on Alveolar Bone Loss Histomorphometrically and Histopathologically on Experimental Periodontitis in Rats.

Background: The aim of this study is to investigate effects of strontium ranelate (SR) on alveolar bone loss (ABL) in rats with experimental periodontitis.

Methods: Forty Wistar rats were randomly divided into five groups: 1) control (n = 8); 2) ligated (n = 8); 3) 300 mg/kg SR (SR300, n = 8); 4) 625 mg/kg SR (SR625, n = 8); and 5) 900 mg/kg SR (SR900, n = 8). To create experimental periodontitis, 4/0 silk ligatures were inserted submarginally around first molars at the right mandible.

Comparative effects of riboflavin, nicotinamide and folic acid on alveolar bone loss: A morphometric and histopathologic study in rats.

Introduction: Periodontitis is a chronic inflammatory and osteolytic disease. Vitamin B complex is a class of water-soluble vitamins that play important roles in cell metabolism.

Objective: The aim of this study was to evaluate the effects of riboflavin (RBF), nicotinamide (NA), and folic acid (FA) on alveolar bone loss in experimental periodontitis rat model.

Evaluation of IL-1β, IL-1ra, and IL-10 levels and outcome of periodontal therapy in chronic periodontitis with familial Mediterranean fever.

Objectives: This study aimed to examine the IL-1β, IL-1ra, and IL-10 cytokine levels in gingival crevicular fluid (GCF) and serum of familial Mediterranean fever (FMF) and chronic periodontitis (CP) patients, and their response to nonsurgical periodontal therapy.

Materials And Methods: A total of 50 patients, 15 FMF patients with generalized chronic periodontitis (FMF-CP), 15 systemically healthy patients with generalized chronic periodontitis (CP), ten systemically and periodontal healthy controls (HC), and ten periodontally healthy FMF patients (FMF-HC) were enrolled in the study. The cytokine levels in GCF and serum were determined by ELISA.

The effect of fixed appliances on oral malodor from beginning of treatment till 1 year.

Background: Orthodontic appliances can enhance plaque accumulation, and this can cause gingival inflammation. Halitosis of oral origin is associated with microbial metabolism on the tongue and in the saliva, dental plaque, and the amount of volatile sulfide-containing compounds. This study used a Halimeter to investigate fixed orthodontic therapy-associated increases in the oral malodor over a year.

Effects of high-frequency bio-oxidative ozone therapy in temporomandibular disorder-related pain.

Objective: It was the aim of this study to compare the efficacy of ozone therapy and drug treatment in patients with painful temporomandibular joint (TMJ) disorder (TMD).

Subjects And Methods: A total of 63 patients with TMD were enrolled; 33 were treated with bio-oxidative therapy and 30 with a ketoprofen tablet thiocolchicoside capsule 2 × 1 for 7 days. Maximum voluntary interincisal mouth opening (MMO) was measured in millimeters using a scale and recorded during the pre- and posttreatment periods.

The effects of non-surgical periodontal therapy on oxidant and anti-oxidant status in smokers with chronic periodontitis.

Aim: The aim of this study was to determine the effect of non-surgical periodontal treatment on gingival crevicular fluid (GCF) and serum oxidant-antioxidant levels in smoking and non-smoking patients with chronic periodontitis.

Methods: Twenty-nine patients with chronic periodontitis (15 smokers (CP-S) and 14 non-smokers (CP-NS)) and 20 periodontally healthy subjects (10 smokers (H-S) and 10 non-smokers (H-NS)) totalling 49 subjects were included in this study. GCF was collected from at least two pre-selected sites (one moderate and one deep pocket) in patients with CP.

Influence of smoking on interleukin-1beta level, oxidant status and antioxidant status in gingival crevicular fluid from chronic periodontitis patients before and after periodontal treatment.

Background And Objective: The aim of this study was to evaluate the impact of smoking on the relationship between interleukin-1 (IL-1β) and oxidation in patients with periodontitis and response to nonsurgical periodontal therapy.

Material And Methods: Data were obtained from 30 patients with generalized chronic periodontitis (15 smokers and 15 nonsmokers) and from 10 periodontally healthy controls. IL-1β level, total oxidant status (TOS) and total antioxidant status (TAS) were recorded in gingival crevicular fluid.
