Soft- and hard-tissue augmentation by orthodontic treatment in the esthetic zone

A technique that may effectively create a greater volume of available hard and soft tissue in the vertical plane without surgical intervention is reported and explained. Limitations of the forced eruption are also discussed. Creating an esthetic implant-supported restoration is a challenge in patients who have alveolar resorption and/or attachment loss, especially when they present with a high smile line. Many methods to augment this loss of tissue have been proposed; most involve surgical procedures to add bone or bone substitutes to compensate for the loss of alveolar tissue. This case report presents an alternative to bone augmentation procedures with the use of orthodontic tooth movement in the esthetic zone of a 62-year-old woman. The tooth movement facilitated implant placement by increasing soft-tissue volume and facial bony contours.     

Interferon Free Hepatitis C Treatment Regimens: The Beginning of Another Era

Hepatitis C is a virus affecting millions worldwide and is a major health risk. With the potentially severe adverse event profile of the current backbone of therapy, interferon, there is an impetus to discover interferon free treatment regimens. With the development of new oral direct acting antivirals, interferon free regimens may be available in the next few years. This article discusses some of the preliminary data from interferon free studies.     

Adhesives for the restoration of non-carious cervical lesions: a systematic review

ObjectivesTo establish whether simplified adhesives (self-etch) are as clinically effective as conventional adhesives (etch-and-rinse) with multiple application steps for treatment of non-carious cervical lesions (NCCLs).Null hypothesis: there is no difference in the clinical effectiveness of the four different bonding strategies: Three-step etch-and-rinse; Two-step etch-and-rinse; Two-step self-etch; One-step self-etch for treatment of NCCLs.SourcesElectronic databases were searched including: Cochrane Oral Health Group Trials Register, the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE and EMBASE. In addition, studies were identified by handsearching of selected journals.Study selectionRandomised controlled trials (RCTs) comparing at least two adhesives in non-carious cervical lesions (NCCLs), with at least 18 months follow-up were selected. The primary outcome was loss of retention/restoration loss, with marginal adaptation and marginal discolouration as secondary outcomes. Criteria for quality assessment included: random sequence generation; allocation concealment; blinding of outcome assessment; and information on withdrawals. Twenty six studies were identified that met the inclusion criteria. In general, studies were not of sufficient quality to fully address the objectives of this review.ConclusionThere is not enough evidence to support one adhesive or bonding strategy over another for treatment of NCCLs. Consequently, the null hypothesis of no difference cannot be supported or rejected with the data currently available. There is a need for better standardisation and reporting of randomised controlled trials investigating adhesive performance.Clinical significanceStudies with low overall risk of bias demonstrated good clinical performance for adhesives with all four bonding strategies. However, included studies showed wide variation between adhesives of the same category.
