Obesity as a modifying factor of periodontal therapy outcomes: local and systemic adipocytokines and oxidative stress markers.

Objectives: Adipocytokines and oxidative stress (OS) are involved in the pathogenesis of both obesity and periodontitis. The aim of this study was to evaluate periodontal therapy outcomes in terms of serum and gingival crevicular fluid (GCF) levels of adipocytokines and OS markers in obese patients with periodontitis, in order to have an insight into the association between obesity and periodontitis.

Materials And Methods: A total of 39 patients (20 obese, 19 non-obese) with periodontitis were included in this study.

Methodological evaluation of gingival crevicular fluid volume and neutrophil elastase levels: sequential sampling, length of sampling time and two different sampling methods.

The mechanisms underlying the formation and composition of gingival crevicular fluid (GCF) and its flow into and from periodontal pockets are not understood very well. The aim of this study was to evaluate the length of sampling time and sequential sampling of GCF neutrophil elastase (NE) enzyme levels by using intracrevicular and orifice methods. Twenty adults (mean age of 41.

Evaluation of long-term effects of diode laser application in periodontal treatment of poorly controlled type 2 diabetic patients with chronic periodontitis.

Purpose: This study aimed to investigate the effects of diode laser (DL) in addition to non-surgical periodontal treatment on periodontal parameters, systemic inflammatory response and serum haemoglobin A (HbA ) level in patients with poorly controlled type 2 diabetes mellitus (T2DM) and chronic periodontitis.

Methods: Thirty-seven patients with poorly controlled T2DM and chronic periodontitis completed this study. The patients were divided into two groups.

Apoptosis: an underlying factor for accelerated periodontal disease associated with diabetes in rats.

Objectives: Diabetes mellitus (DM) is well-established risk factor for periodontal disease. DM can also lead to changes in the number of apoptotic cells in periodontal tissues. The goal of this study was to evaluate apoptosis, depending on DM, in healthy and diseased periodontal soft tissues.

Immunohistochemical analysis of CD45RO+ T cells and vascular endothelial growth factor expression in cyclosporin A-induced rat gingival tissue.

Background: The aim of this study is to evaluate CD4(+), CD8(+), and CD45RO(+) T cells, and vascular endothelial growth factor (VEGF) expression in cyclosporin A (CsA)-induced rat overgrown gingival tissue during an 8-week period.

Methods: Sixty male Sprague-Dawley rats weighing 200 to 250 g were used in this study. Mandibular first molars were ligated with 3-0 silk suture.

Periodontitis as a risk factor for preterm low birth weight.

Purpose: There is growing evidence showing that a number of complex human diseases are caused or are at least influenced by periodontal diseases. Such diseases include cardiovascular diseases, respiratory diseases, diabetes mellitus and osteoporosis. The aim of study was to evaluate periodontal diseases as a risk factor for a preterm low birth weight.

The effect of endodontic therapy on periapical exudate neutrophil elastase and prostaglandin-E2 levels.

This study aimed to investigate periapical exudate neutrophil elastase (NE) and prostaglandin E2 (PGE2) levels and their relationships with clinical symptoms, and to determine the changes of their levels following first treatment visit. Periapical exudate samples were collected from the canals of 34 nonvital single-rooted teeth at two sequential treatment visits. Periapical exudate NE and PGE2 levels were found to be higher in the presence of clinical symptoms (pus discharge, swelling) (p < 0.

Periodontal treatment of two siblings with juvenile hyaline fibromatosis.

Background And Aim: Juvenile hyaline fibromatosis (JHF) is an autosomal recessive disease that presents with multiple subcutaneous nodular tumours, gingival fibromatosis, flexion contractures of the joint and hyaline material accumulation in extracellular area. Recently, the causative gene for JHF, capillary morphogenesis protein 2 (CMG2) was identified. In this case report, periodontal status, treatment and follow-up together with histopathologic evaluation of gingival tissue specimens and mutation screening of two JHF cases are presented.

Periodontal status in two siblings with severe congenital neutropenia: diagnosis and mutational analysis of the cases.

Background: Severe congenital neutropenia (SCN), also known as Kostmann syndrome, was originally reported as an autosomal recessive disease of neutrophil production. The disease is characterized by a maturation arrest of neutrophil precursors at the promyelocytic stage of differentiation and by extremely low levels of mature neutrophils in peripheral blood.

Methods: A 6-year-old male presented with a complaint of gingival swelling and bleeding, and swelling at the left side of his face.

Neutrophil elastase levels in periapical exudates of symptomatic and asymptomatic teeth.

The aim of this study was to determine neutrophil elastase levels (NE) in periapical exudates and to evaluate its relationship with clinical signs and symptoms of endodontically involved teeth. A total of 42 teeth with periapical periodontitis of 37 patients were clinically examined and spontaneous pain, swelling, pain on palpation or percussion, sinus tract formation and pus discharge were recorded. Additionally, periapical lesion size was measured on periapical radiographs.

Critical steps in electronic volume quantification of gingival crevicular fluid: the potential impact of evaporation, fluid retention, local conditions and repeated measurements.

Background And Objectives: Various methodological factors may operate during clinical gingival crevicular fluid (GCF) sampling, volume quantification or subsequent laboratory analysis. For precise volume quantification, specific concern for generation and maintenance of a reliable calibration curve, the potential risk of GCF loss as a result of evaporation or fluid retention on actual volume and the impact of local conditions is needed because each of these factors may act as a source of subsequent volumetric distortions. Thus, the present study aimed to analyse the impact of sample transfer time on the rate of evaporation and the possibility of fluid retention, and the impact of local conditions and number of replicated measurements on the reliability of calibration data.

Interleukin-1beta, tumor necrosis factor-alpha levels and neutrophil elastase activity in peri-implant crevicular fluid.

The aim of this study was to determine interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha) levels and neutrophil elastase (NE) activity in peri-implant crevicular fluid (PICF) of smoker and nonsmoker patients, and to investigate their relationships with clinical parameters. A total of 42 endosseous root-form dental implants of 14 patients were clinically examined by modified Plaque index (PI), modified Gingival index (GI) and probing depth (PD). Smoking habits of the patients were recorded.

A rare case of gingival myiasis caused by diptera (Calliphoridae).

Myiasis was first described by Hope in 1840. Since then, many cases of myiasis affecting different human organs have been reported. Oral myiasis is very rare in healthy persons but occurs mainly in the tropics and associated with inadequate public and personal hygiene.
