Beautifil and FL-Bond from Shofu: reliable and successful 8-year clinical results

Dr. Smile 11 October, 2008 | The practising dentists are often not informed about the important results of long-term clinical studies which are neglected in times of outrunning material generations. In many cases in vitro studies and 3 to 6 months results only provide the data based on which a decision in favour for or against a product has to be made. Against this trend a clinical study on the SHOFU restorative material, Beautifil, a composite, and FL-Bond, a self-etching adhesive system, is now available. Under the direction of Prof Dr Ivar A. Mjör, University of Florida, Gainesville, USA, this restorative material has been tested in Class I and II cavities with positive results. Two clinicians placed 26 Class I and 35 Class II restorations in 31 patients. The restorations have been examined after a period of 6 months respectively one, two, three, four and eight years. The restorations have been examined by using modified Ryge criteria for colour match, marginal adaptation, anatomy, surface roughness, marginal and interfacial staining, proximal and occlusal contacts, secondary caries, postoperative sensitivity and luster. 16 Class I and 25 Class II restorations were examined after the impressive period of 8 years. The self-etching adhesive system FL-Bond and Beautifil, a microhybrid composite, both manufactured by SHOFU Inc., Japan, have been used. About half of the silicate glass filler of the composite is coated by the PRG technology patented by SHOFU, thus enabling a continuous fluoride recharge and release. During the eight-year period no changes with respect to surface roughness, postoperative sensitivity or secondary caries were detected. Associated with the latter observation the potential of the composite regarding the fluoride release is particularly discussed. The majority of changes recorded were for marginal adaptation and marginal stainings; however they have been rated from Alfa to Bravo ? no Charlie rating was recorded. The clinicians observed minimal changes with regard to colour match, anatomical form, contact points and luster. The study documents the positive clinical performance of FL-Bond and Beautifil in Class I and Class II cavities after eight years. Beautifil is available in kits, syringes and pre-filled tips. In addition, Beautifil Flow is available in high flow (F10) and low flow (F02) viscosities. | |

Interesting results, I had not heard about Beautifil Flow before.
