OBJECTIVE: The objective of the study is to compare the clinical, microbiological and host-derived effects in the non-surgical treatment of initial peri-implantitis with either adjunctive local drug delivery (LDD) or adjunctive photodynamic therapy (PDT) after 12 months. MATERIALS AND METHODS: Forty subjects with initial peri-implantitis, that is, pocket probing depths (PPD) 4-6 mm with bleeding on probing (BoP) and radiographic bone loss ≤2 mm, were randomly assigned to two treatment groups...

Air-polishing is a well-known and common technique to remove plaque, tartar and different kind of stains from teeth, using abrasive materials. Commonly used cleaning powders contain Al (aluminium) which is still controversial in terms of its inertness and harmfulness for human body. Nowadays, new air-polishing materials, including biomaterials, are being introduced. In particular, biomaterials the structure of which imitates that of natural tissue are very promising materials of reparative and reconstructive features...

OBJECTIVE: To compare the adjunctive clinical effects in the non-surgical treatment of peri-implantitis with either local drug delivery (LDD) or photodynamic therapy (PDT). MATERIAL AND METHODS: Forty subjects with initial peri-implantitis, i.e. pocket probing depths (PPD) 4-6 mm with concomitant bleeding on probing (BoP) and marginal bone loss ranging from 0.5 to 2 mm between delivery of the reconstruction and pre-screening appointment were randomly assigned to two treatment groups...

PURPOSE: The aim of the present study was to evaluate the alterations of surface microhardness and wear caused by the sodium bicarbonate jet on bovine enamel and the further remineralizing effect of artificial saliva. METHODS: Fifteen enamel samples (4,0mm x 4,0mm) were used, which constituted the groups: no treatment (MI); treatment with sodium bicarbonate jet (MII and DI); treatment with sodium bicarbonate jet and immersion in saliva for one hour (MIII and DII), 24 hours (MIV and DIII) and 7 days (MV and DIV)...

INTRODUCTION: JET-Fresh (Dentsply International, York, PA), a new airpolishing powder that contains aluminum trihydroxide as the abrasive agent, has been introduced for use with Prophy-Jet trade mark (Dentsply International). PURPOSE: The aim of this study was to investigate the surface effects of aluminum trihydroxide airpolishing powder on a series of restorative materials. MATERIALS AND METHODS: A total of 6 Class V preparations with enamel margins were created on the buccal surface of extracted human molars...

The aim of this in vitro study using implants and abutments was to examine traces left by various cleaning instruments and to determine the quantity of substance removal. The implants and relevant abutments were Screw-Vent implants (Dentsply), titanium plasma-coated full-screw implants (Straumann), and standard Brånemark implants (Nobel Biocare). The instruments used were titanium curettes, Gracey curettes, plastic curettes, rubber cups with Zircate prophy paste, the Cavitron Jet ultrasonic scaler with universal inserts and airpolishing nozzles with Prophy-Jet cleaning powder, and the Densonic sonic scaler with SofTip disposable prophy tips and universal tips...

An air-powder abrasive system was tested among 20 volunteers, who had healthy gingiva or slight gingivitis, but no periodontal pockets. Impressions of randomly selected areas (n = 103) were taken before and after airpolishing and positive replicas were prepared for scanning electron microscopy (SEM). Gingival bleeding increased statistically significantly (p less than 0.001) during the treatment. Also gingival erosive changes were increased when using airpolishing technique (p less than 0.001). The erosive changes observed by SEM and the subjective symptoms during and after the operation positively correlated to the presence of gingival inflammation (p less than 0...

The effect of two airpolishing systems on the surface roughness of polished ceramic test pieces was compared and evaluated using standardized procedures. Test pieces resembling enamel in hardness were treated with these air-polishing systems. Using a Perthometer surface roughness was found to increase significantly. Thus the possible effects of airpolishing systems on the enamel surface should be considered. Efficiency of extrinsic stain removal was studied by SEM and documented. Photographic techniques provided information on the homogeneity of the sodium bicarbonate spray...

The effect of an air-powder abrasive system on dental hard tissues was tested on 20 volunteers. Impressions of 150 randomly selected areas were taken before and after airpolishing and positive replicas were prepared for scanning electron microscopic examination (SEM). The amount of dental plaque on tooth surfaces was reduced by the treatment (P less than 0.001). The abrasive changes caused by airpolishing on enamel were greater on the surfaces covered by dental plaque before the airpolishing compared to the surfaces without plaque (P less than 0...

This study was designed to compare the clinical effectiveness of rubber cup polishing and airpolishing. Polishing time was controlled to approximate the time spent on plaque and stain removal in clinical dental hygiene practice. Effectiveness of polishing techniques was evaluated using indices to measure plaque, stain, and gingival trauma prior to and after the polishing treatment. Thirty adult subjects, with comparable numbers of teeth contralaterally, exhibiting observable plaque and stain, participated in the study...
