ABSTRACT Bonding composite resin to enamel of teeth affected by amelogenesis imperfecta (AI) is often problematic, especially in cases with poorly mineralized, friable enamel. Difficulty in bonding hypomineralized enamel can significantly limit the restorative and orthodontic treatment options for AI patients. In this report, we document a novel approach to bonding AI enamel by pretreating the tooth surface with 5% sodium hypochlorite (NaOCl), resulting in improved bonding of an orthodontic bracket to a previously impacted maxillary canine.

    ABSTRACT: Approximately ten percent of patients who seek orthodontic treatment have experienced a Traumatic Dental Injury (TDI). TDI occurs in different age groups ranging from preschool children to adults. Both primary and permanent teeth can be injured, and the sequelae of TDI complicate orthodontic treatment. This article gives a review on the epidemiology and etiology of TDI, and also the relation between TDI and orthodontics.

    ABSTRACT: The biggest challenge restorative dentists face in rehabilitating patients with amelogenesis imperfecta (AI) is trying to restore aesthetics, function and occlusal stability while keeping the treatment as conservative as possible. The goals of treatment should be to prolong the life of the patient's own teeth and avoid or delay the need for extractions and subsequent replacement with conventional fixed, removable or implant retained prostheses. In order to achieve these goals a stepwise approach to treatment planning is required starting with the most conservative but aesthetically acceptable treatment. This article discusses the management of AI and presents the various treatment options available for restoring the adult patient who presents to the dentist with AI.

    ABSTRACT: Reduced bond strengths of resin composites to hypomineralised enamel increase restorative failure. To investigate if the adhesion of resin composite to hypomineralised enamel can be improved by pre-treatments: resin infiltration, oxidative pre-treatment followed by a resin infiltration, or oxidative pre-treatment. Twenty-one enamel specimens in each of five Groups: 1) Normal enamel; 2) Hypomineralised enamel; 3) Hypomineralised enamel pre-treated with a resin infiltrant, (Icon(®) ); 4) Hypomineralised enamel pre-treated with 5.25% sodium hypochlorite then treatment with resin infiltrant; 5) Hypomineralised enamel pre-treated with 5.25% sodium hypochlorite. A resin composite rod was bonded to each specimen using Clearfil™ SE bond as the adhesive (hereafter termed 'routine bonding'), then subjected to microshear bond strength (MSBS) testing. Overall, the mean MSBS between the five groups differed significantly (P = 0.001). Pre-treatment of hypomineralised enamel with 5.25% sodium hypochlorite with or without subsequent resin infiltration in Groups 4 and 5 prior to routine bonding resulted in increased mean MSBS compared to Groups 2 and 3, with mean MSBS values not differing significantly when compared to routine bonding to normal enamel. Increased bond strength of resin composite to hypomineralised enamel was obtained by pre-treatment of hypomineralised enamel specimens with 5.25% sodium hypochlorite with or without subsequent resin infiltration.
