Lasers in periodontology.

Since the development of the ruby laser by Maiman in 1960, lasers have been widely employed in medicine for a number of years. The purpose of this paper is to summarize potential applications for lasers in dentistry, with special regard to periodontology. This article briefly describes clinical applications of lasers and laser safety. Particularly, the use of a diode laser seems to be promising, especially in already compromised transplant patients, who need to be treated with a technique where the operative and post-operative blood loss, post-operative discomfort and the recurrence of drug-induced gingival overgrowth need to be kept to a minimum or eliminated. Therefore, the use of lasers in periodontology may lead to an alteration in present clinical practice and help to establish the best management strategy because, by maintaining periodontal health, the life quality of patients can be improved.

Vital tooth bleaching in dental practice: 1. Professional bleaching.

UNLABELLED: As dental health improves, with the concurrent drop in the provision of basic restorative care, patients are now asking their dentists to provide aesthetic treatments rather than the treatment of disease. Tooth bleaching is one such treatment that is frequently described in consumer magazines and television shows, driving consumer interest in this, apparently, benign therapy. This three-part series demonstrates the techniques that can be employed, within the dental practice or under the supervision of a clinician, those systems that can be bought by patients over the counter and, finally, a discussion of the biological effects of peroxide-containing solutions and the legal position on such products in the UK. In this section, we will describe the common methods by which teeth can be bleached, either by the clinician directly, or under his/her supervision by the use of'at home' kits. Efficacy and safety issues will be described. CLINICAL RELEVANCE: Clinicians should be able to discuss the merits, risks and likely success of a variety of bleaching treatments with their patients and, in doing so, assist in the process of obtaining informed consent.

Vital tooth bleaching in dental practice: 3. Biological, dental and legal issues.

UNLABELLED: The final section of this series examines both the evidence for the safety of external bleaching with hydrogen peroxide and related products and the legal position in the UK with regard to their sale and use in general dental practice. Potential side-effects are examined, including biological effects and dental effects, with a review of the current evidence. The EU Cosmetics and Medical Device Directive are both described and their impact on the provision of tooth bleaching in the UK is explained. The legal position in the UK renders the sale and supply of solutions containing >0.1% peroxide illegal, and practitioners must be aware of the underlying legislation and the basis upon which a prosecution may be pursued. CLINICAL RELEVANCE: Clinicians considering using hydrogen peroxide products must be aware of the safety issues surrounding their use and be able to explain to patients the nature of the risk and also the likelihood of any given patient experiencing them.

Endodontic classification.

Clinical and histopathologic findings are mixed in current endodontic classifications. A new system, based on symptomatology, may be more useful in clincial practice. The classifications are vital asymptomatic, hypersensitive dentin, inflamed-reversible, inflamed/dengenerating without area-irreversible, inflamed/degenerating with area-irreversible, necrotic without area, and necrotic with area.

An evaluation of two methods for the quantitation of dentinal hypersensitivity.

In a well-controlled, double-blind, parallel study design using burnishing with 33% sodium fluoride paste and "sham" burnishing with a placebo paste, both a cold air stimulus method and an electrical stimulus method can discriminate between levels of dentinal hypersensitivity. Correlation between the scores obtained by the methods was significant. The electrical stimulus method discriminated between the sodium fluoride and placebo effects to a greater degree than did the cold air method. Use of these methods should broaden the scientific foundation and rationale for evaluating the condition of dentinal hypersensitivity and the agents designed for treatment of persons with this condition.

The placement of bases beneath amalgam restorations: review of literature and recommendations for use.

On the basis of the literature, it can be concluded that there are no absolute rules regarding the placement of bases under amalgam restorations. The following recommendations are offered: A base should not be used unless its use is indicated clearly. When a base is indicated, it should be used with the minimum thickness necessary to achieve the desired result. Lost dentin should not be replaced with a base in an attempt to simulate an ideal preparation. A stronger base should not be placed over a weaker base, for strength. The entire base is only as strong as the weakest component. Covering the entire pulpal floor with a base should be avoided. Sound dentin surrounding the base should be left so that the amalgam restoration is supported by dentin as much as possible.

Cyanoacrylate--a new treatment for hypersensitive dentin and cementum.

Hypersensitivity that causes chronic pain and discomfort in exposed cementum and dentin, and the various therapeutic agents and treatment regimens that have been tried to alleviate this condition are considered. The desensitizing effects of cyanoacrylate compared with 33% sodium fluoride paste were evaluated for 6 weeks.

An evaluation of a glass ionomer luting agent: pulpal histological response.

Pulpal histological response after crown cementation with a glass ionomer luting agent was evaluated and compared with the response to a polycarboxylate cement or a varnish plus zinc phosphate cement. Pulpal histological response was evaluated on teeth that had full crowns cemented with the test luting agents 3, 10, and 56 days after cementation. No statistically significant differences were found in pulpal histological response between the materials tested during all periods. These findings suggest that factors other than pulpal inflammation are contributing to the reported hypersensitivity after cementation associated with glass ionomer luting agents.

Twelve-month clinical study of dentinal adhesives in class V cervical lesions.

Recently, numerous resin systems claiming dentinal adhesive properties have been introduced. This study evaluated the clinical performance of two such adhesive resins in seven various material and technique combinations without conventional cavity-retention features. To identify potential risk factors in regard to retention, nonmaterial- and technique-related variables such as patient age and occlusion were also evaluated.
