BACKGROUND The aim of this study is to determine in a randomized trial the impact on treatment outcome after 12 months of different subgingival irrigation solutions during scaling and root planing (SRP). METHODS Fifty-one adult volunteers with generalized chronic periodontitis were treated by full-mouth SRP using 0.9% sodium chloride, 0.12% chlorhexidine(More)
The aim of this study was to estimate differences in the prevalence of oral streptococcal species in the subgingival biofilm of patients with aggressive periodontitis and of healthy controls. Thirty-three patients with clinical and radiological proof of aggressive periodontitis and 20 healthy subjects were enrolled in this study. Clinical indices were(More)
OBJECTIVES The aim of the study was to verify (i) if crevicular fluid defence variables reflect the changes after surgical periodontal treatment and (ii) if they are in correspondence with changes of these variables in the unstimulated and stimulated whole saliva. MATERIAL AND METHODS For 12 male and 13 female volunteers with chronic periodontitis(More)
The impact of a semiquantitative commercially available test based on DNA-strip technology (microIDent®, Hain Lifescience, Nehren, Germany) on diagnosis and treatment of severe chronic periodontitis of 25 periodontitis patients was evaluated in comparison with a quantitative in-house real-time PCR. Subgingival plaque samples were collected at baseline as(More)
AIM The aim of this study was to determine the effect of a probiotic milk drink on gingival health and the development of experimental gingivitis. MATERIAL AND METHODS Fifty volunteer students took part in a parallel-designed non-blinded study. The test group drank a probiotic drink once a day; the control group did not receive any product to drink. After(More)
OBJECTIVES Hyaluronic acid (hyaluronan) is a glycosaminoglycan with anti-inflammatory and antiedematous properties. It was evaluated in a gel formulation for its effect in the treatment of plaque-induced gingivitis. METHOD In a randomised double-blind study, 50 male subjects with plaque-induced gingivitis were divided into two groups and used a verum or(More)
The role of nutrition in onset, progression and treatment of periodontitis has not been thoroughly evaluated. In the present prospective clinical study, we investigated the influence of a nutritional intervention on changes in clinical, microbiological and immunological periodontal variables during a period of 12 months in patients with the metabolic(More)
The aim of this in vitro study was a comparative investigation of tooth-composite interface morphology and microleakage formation after the calibrated restoration of Class II cavities with a proven multi-component, three-step, total-etch adhesive system by three experienced operators. The current study also aimed to acquire data about the well-tried(More)
OBJECTIVE To determine in vitro the action of chlorhexidine digluconate and different commercially available mouthrinses on oral microorganisms. METHOD AND MATERIALS Minimal inhibitory concentrations and possible induction of resistance by chlorhexidine digluconate, an essential oil-containing mouthwash and an amine fluoride/stannous fluoride solution,(More)
The focus of this study was to examine in vitro the effects of stress hormones (catecholamines: epinephrine, norepinephrine, dopamine and hydrocortisone: cortisol) on the growth of four anaerobic species of periodontitis-related bacteria (Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella intermedia and Tannerella forsythia) and one facultative(More)
