RESUMO

Background: The aim of present study was to clinically assess and compare a sonic toothbrush versus a rotating oscillating power toothbrush on plaque removal and gingival health in reducing plaque and bleeding on probing. Methods: Patients were selected according to specific inclusion and exclusion criteria and they were enrolled in test group or control group using Random Allocation Software. Visual score plaque index (PI) was recorded by the same blind operator using a plaque revelator and bleeding on probing (BoP) index was recorded using a periodontal probe at baseline, 15th day and 30th day. Results: The group of patients who used sonic toothbrush showed a greater reduction of PI and BoP comparing with patients who used rotating-oscillating power toothbrush. Conclusions: Although this pilot study has several limitations, it seems to indicate that sonic toothbrushes are capable of removing plaque and reducing bleeding on probing better than electric toothbrushes.

RESUMO

Introduction: Over the years, several different implant systems have been introduced, and the indications for implant rehabilitation have gradually been extended 2. Although an high success rates have consistently been reported for many implant systems, complications leading to loss of osseointegration still occurs 3. Thus, oral hygiene and maintenance are imperative, because implants, as well as teeth, are susceptible to accumulation of bacterial plaque and calculus formation. The aim of the present study was to evaluate and compare the in vivo cleaning efficacy of the three systems (air powder, curette, laser) comparing at the same time the alterations of the titanium abutment surface in terms of roughness. Methods: Forthy-two patients (25 males and 17 females) were included in the study. The 42 healing abutments were treated by the same clinician (UC). Results and conclusions: The rate of debris removal by the air powder was higher than that for the laser and than that for the curettes. The SEM analysis showed that the air powder system did not induce significant differences of the abutment if compared to the curettes as well as to the laser.

RESUMO

INTRODUCTION: After scaling and root planning (SRP), healing induces the formation of a junctional long epithelium rather than a new connective attachment. We hypothesize that the placement of a periodontal dressing will be able to prevent detachment of coagulum inducing proper healing and improving periodontal parameters. MATERIALS AND METHODS: This split-mouth study included 30 patients with periodontitis with ages ranging from 35 to 70 years. Probing pocket depth (PD), probing attachment level (PAL), bleeding on probing index (BoP) and plaque index (PI) were assessed before and after therapy. The group of patients received SRP in a span of 24 h. Then, a periodontal dressing was applied on the test side and it was removed after 1 week. CONTROL GROUP: The difference between PD values at baseline and after therapy was 1.6 ± 0.6 mm. The difference in PAL (ΔPAL) measurement was 1.4 ± 0.4. Test group: there was a greater PD reduction, this being 2.4 ± 0.6 mm on average. The difference in PAL was 2.5 ± 0.4 mm. CONCLUSIONS: Our results clearly suggest that the use of a periodontal dressing improves the periodontal parameters after an SRP procedure. This is probably due to clot stabilization and prevention of bacterial colonization during wound healing.

RESUMO

AIM: Recent research has focused attention on the single nucleotide polymorphisms (SNPs) involved in the host response in periodontitis. However, so as to combine the relatively small effects of individual genes the use of multi locus genetic risk (GRS) has been proposed. This study aims to evaluate whether the genetic risk score may predict periodontitis onset and progression. MATERIALS AND METHODS: Fifty patients were divided into various groups according to periodontal status. Total DNA was isolated from epithelial oral cells by a masked operator and the selected SNPs were analysed. A GRS was calculated using an additive model. RESULTS: We found a strong association only between TNF rs1800629 and diffused forms of periodontitis. Data show that GRS is able to discriminate diffused forms of periodontitis from localized ones. Finally, a progressive increase of the GRS is evident in advanced periodontitis in comparison with early forms. DISCUSSION: In recent years, research on genetic polymorphism has had limited success in predicting the susceptibility to periodontal disease. However, our results indicate that the use of the genetic risk score could be promising. Further studies are necessary to include data from multiple genes so as to confirm our result.

RESUMO

UNLABELLED: CODE 75 is a neurorehabilitation department at the General Hospital of Versilia, which specializes in serious acquired cerebral lesions. OBJECTIVES: The therapy and the maintenance of oral hygiene in patients with cerebral lesions are critical to the overall success of the rehabilitation therapy. The purpose of our project was to improve patients' quality of life, reducing the quantity of oral bacteria caused by the presence of layers of plaque on the tooth surfaces and in the oral mucosa. METHODS: The dental department of Versilia Hospital conducted a 1 year follow-up study to develop specific protocols designed to obtain and improve the maintenance of these patients' oral hygiene. The oral prevention project was directed primarily at the department's medical staff and carers, and focused on improving the information available to the medical team and their direct involvement. A case report is described to show an application of the protocol. Data were recorded before the start of the protocol (T0) and after 1 month (T1). RESULTS: The analysis of the periodontal parameters shows a difference in values between T0 and T1. In T1 no bleeding on probing was recorded. After the causal therapy, the gingival hypertrophy and oedema disappeared as confirmed by the absence of BOP. DISCUSSIONS: Results show that teamwork plays a fundamental role in this multi-professional approach for the rehabilitation of patients with acquired cerebral lesions. The success of this protocol depends on the cooperation between personnel with specific skills in the department.

RESUMO

Dental caries and resulting tooth decay can produce a multifactorial destructive process with a very high incidence. Cariogenic bacteria attack enamel with acids that produce subsurface lesions, thereby weakening the enamel and allowing bacterial progression into the dentin. The formation of dental decay, because of demineralization of the tooth structure, can be prevented or delayed by increasing the rate of the tooth's remineralization and replacement relative to the tooth's rate of demineralization. This rebuilding of enamel may be accelerated by the addition of amorphous calcium phosphate (ACP) with the aid of casein phosphopeptide (CPP) (Recaldent molecule). In this study, the role of CPP in stabilizing and releasing ACP on the tooth surface has been investigated to better understand its efficacy in the prevention of tooth demineralization in orthodontic patients. Twenty-five patients who wore fixed orthodontic appliances were enrolled in this clinical trial. It was explained to the patients that CPP-ACP would be used for 3 weeks and then suspended for an additional 3 weeks. Salivary pH evaluation, plaque pH evaluation and oral hygiene index (OHI) were performed at T0, T1 and T2. Results showed an increase in OHI level and an increase of the salivary pH (76% of the patients). Instead of plaque pH level that showed trivial results, only 48% of the patients showed a bacterial plaque pH increase. In conclusion, this study has not provided unequivocal evidence for the protective properties of Recaldent molecule. Long-term studies are necessary to better understand the role of this molecule.
