Oral tongue cancer in public hospitals in Madrid, Spain (1990-2008).

Background: The cancer which appears in the mobile portion of the tongue is the most common neoplasm of the oral cavity. The objective of this study was to analyse oral tongue cancer epidemiology in a population of 610 patients diagnosed between 1990 and 2008 and detailed in the Tumour Registry of the Madrid region.

Material And Methods: A retrospective analysis based on the following variables provided in the Tumour Registry was achieved: age, gender, histology, stage, location, treatment.

Analysis of the expression of heat-shock protein 27 in patients with oral lichen planus.

Objective: Heat-shock protein 27 (hsp27) has been implicated in several biological events. In this experimental study, we aimed at analysing, for the first time, the expression of hsp27 in the diverse stages of oral lichen planus (OLP) lesions.

Materials And Methods: Thirty-six biopsy specimens of patients with OLP and 10 of healthy patients were selected.

Adjunctive Nd:YAG laser application in chronic periodontitis: clinical, immunological, and microbiological aspects.

In recent years, the use of laser radiation has been investigated as an alternative or adjunctive tool to conventional procedures employed in the treatment of periodontal disease. Various beneficial characteristics of Nd:YAG laser radiation, such as hemostatic and bactericidal effects, might lead to improved treatment outcomes. The objective of the present study was to examine the clinical, microbiological, and anti-inflammatory efficacy of Nd:YAG laser periodontal pocket irradiation as an adjunct to scaling and root planing (SRP).

IL-1beta, TNF-alpha, total antioxidative status and microbiological findings in chronic periodontitis treated with fluorescence-controlled Er:YAG laser radiation.

Background And Objective: Although some studies have attempted to elucidate the possible advantages of the use of Er:YAG laser radiation as a coadjuvant of scaling and root planing (SRP), the results have often been contradictory. A new possibility to improve the results of the laser therapy is the control of the laser radiation by a feedback system that selectively detects subgingival calculus. This study compared the effects of fluorescence-controlled Er:YAG radiation after SRP with SRP alone on the treatment of chronic periodontitis.

Effect of two kinds of Er:YAG laser systems on root surface in comparison to ultrasonic scaling: an in vitro study.

Objective: To evaluate the capacity of Er:YAG laser application to eliminate calculus from periodontally affected root surfaces compared with ultrasonic scaling (US), as well as the possible root damage incurred from both types of instrumentation.

Background Data: The benefits of the use of the Er:YAG laser as a coadjuvant to conventional periodontal therapy have not yet been determined.

Materials And Methods: Forty human molars extracted due to advanced periodontal disease were used.
