Effect of autogenous cortical bone particulate in conjunction with enamel matrix derivative in the treatment of periodontal intraosseous defects.

Background: The aim of the present study was to assess the additional clinical benefit of autogenous cortical bone particulate (ACBP) when added to enamel matrix derivative (EMD), compared to EMD alone, in the treatment of deep periodontal intraosseous defects.

Methods: A total of 28 intraosseous lesions in 27 patients with advanced periodontitis were included in this controlled clinical trial and randomly assigned to the EMD group (14 defects) or to the EMD + ACBP group (14 defects). Immediately before surgery (baseline) and after 6 and 12 months, probing depth (PD), clinical attachment level (CAL), and gingival recession (REC) were recorded.

Autogenous bone graft in conjunction with enamel matrix derivative in the treatment of deep periodontal intra-osseous defects: a report of 13 consecutively treated patients.

Aim: The purpose of the present study was to investigate the effectiveness of a regenerative procedure based on supra-crestal soft tissue preservation in association with combined autogenous bone (AB) graft/enamel matrix derivative (EMD) application in the treatment of deep periodontal intra-osseous defects.

Methods: Thirteen consecutively treated patients, seven females and six males, aged 30-65 years, three smokers, were included. A total of 15 deep, one- to two-wall intra-osseous defects were selected.

[Water absorption by denture base resins].

In a review of the international literature about water absorption of denture base resins any effect on the physical properties of these polymers has been considered. The authors discuss the possibilities of controlling the final results on denture base function.

[Orthodontic treatment and periodontal injury].

The authors examine the literature about the relationship between orthodontic treatment and periodontal tissues health and consider the problems relating to orthodontic therapy in periodontopatic patient.

An extensive review of the scientific literature for evaluating the current status of luting cements solubility. Both in vitro and in vivo results have been examined and discussed.

[Use of synthetic membranes in periodontal guided tissue regeneration].

Authors evaluated health's possible mechanisms of periodontal lesion and, having they studing most recent literature, they underline large possibilities of using synthetic membranes in order to having guided regeneration of periodontal tissues.

["Maryland Bridge" technique and its possible use in periodontology].

The authors describe the Maryland Bridge technique relating to more recent acquisitions and consider some possible indication in periodonatal disease patients.

[Chlorhexidine in the prevention of periodontal disease].

Authors considering microbiological and clinical characteristics of chlorhexidine pointing out its notable capacity to inhibit bacterial plaque formation and analyze possible collateral effects by its use.

[Diagnosis of the active phase of periodontal disease. 1. Clinical parameters].

Review of the literature shows that the common clinical parameters used in practice are inaccurate in assessing periodontal disease activity. Radiographs and probings are, instead, relatively accurate in retrospectively assessing periodontal disease activity. Currently more sophisticated radiographic techniques are being developed to diagnose ongoing periodontal disease activity.

A microcomputer-based emergency response system*.

A microcomputer-based system was developed to provide local officials responsible for disaster management with assistance during the crucial period immediately following a disaster, a period when incorrect decisions could have an adverse impact on the surrounding community. While the paper focuses on a potential disaster resulting from an accident at a commercial nuclear power generating facility, the system can be applied to other disastrous situations. Decisions involving evacuation, shelter and the deployment of resources must be made in response to floods, earthquakes, accidents in the transportation of hazardous materials, and hurricanes to name a few examples.
