Anterior veneers for the adolescent patient: 1. General indications and composite veneers.

Composite and porcelain veneers offer a conservative method of masking discolouration of the teeth of younger patients. Composite veneers are the less destructive of tooth tissue, but also the less durable. This two-part article reviews the use of veneers in treating the adolescent patient. Part 1 examines indications for treatment and gives a step-by-step guide to the clinical procedure for veneering with composite. Next month, Part 2 will cover porcelain veneers and draw some overall conclusions.

Should etching be performed as a part of a vital bleaching technique?

Many clinicians advocate etching the teeth before vital bleaching as a way to enhance the permeability of the tooth surface to hydrogen peroxide and thus to enhance the bleaching effect. However, no studies have been published to date to document the effect of etching on vital bleaching. In this study, ten patients received a bleaching treatment regimen of several appointments. Half of the teeth in one arch of each patient were etched with phosphoric acid for 20 seconds before they were bleached with 35% hydrogen peroxide. The teeth in the other half of the same arch were treated with tap water prior to bleaching. Evaluations of the patients after 3 and 6 weeks failed to confirm any enhanced lightening effect from etching.

[Bleaching of nonvital teeth].

The bleaching of non vital teeth that is described in this article has demonstrated to give good clinical results, and because of its easy way to apply we believe that it is the option for the treatment of this teeth, as long as we have a good an realistic diagnostic considering the results we may obtain. One the selection has been made we proceed to the bleaching, the substances that we use are easily obtain, superoxol and sodium perborate. The preparation of the tooth began with the removal of any restauration or decayed tissue that is may present after this we remove the material from the pulp chamber 1 mm below the gingival margin, then clean perfectly the chamber, then we deshidrate the tubulae, then put a pellet of cotton on the vestibular wall of the chamber, put some superoxol in the cotton, heat it up, remove the cotton, put some sodium perborate and hidroge peroxide paste in the chamber and seal it with cavit, and wait from 3 to 7 days for results.

A simple technique for removal of mottling, opacities and pigmentation from enamel.

Mottling of teeth can have significant psychological impact on patients--particularly on adolescents, who may be subjected to much unkind teasing. A number of procedures have been suggested for removal of mottling and stains. The authors describe a simple and quick technique using a paste of hydrochloric acid and pumice, and on the basis of their clinical and laboratory experience suggest it as a treatment of first choice.
