ABSTRACT
The available methods for veneer evaluation are limited to clinical and radiographic examinations, which may not allow the appropriate identification of failure. In this report, we demonstrate the use of optical coherence tomography (OCT) as a noninvasive diagnostic and follow-up method to evaluate gingival recovery and the adhesive interface in aesthetic oral rehabilitation involving periodontal plastic surgery and ceramic laminate veneers. OCT was efficient for evaluating both soft and hard tissues, as well as the quality of the adhesive interface. In conclusion, OCT was found to be a promising approach for the professional evaluation of aesthetic oral rehabilitation, as it was capable of generating images that enabled the analysis of gingival recovery and the adhesive interface.

O objetivo da dentística o de preservar a estrutura dental sadia e o recompor do tecido perdido, buscado, através do emprego de materiais e técnicas restauradoras adequadas, evitar recidivas, devido ao aparecimento de novas lesões de cárie dentária. Dentre esses materiais, os que mais se destacam, pelo caráter terapêutico, são os cimentos de ionômero de vidro. Este trabalho objetivou realizar uma revisão sistemática acerca das publicações sobre as propriedades físicas, mecânicas e biológicas dos cimentos de ionômero de vidro, de forma a avaliar os resultados encontrados na literatura. As publicações foram selecionadas a partir de uma pesquisa em base de dados (Medline - Literatura Internacional em Ciências da Saúde, BBO - Bibliografia Brasileira de Odontologia e Scopus) no período de 2000 a 2008, utilizando os termos: cimento de ionômero de vidro, propriedades mecânicas e biocompatibilidade. Pode-se observar que houve uma certa padronização nas metodologias, o que facilitou a comparação dos trabalhos. A maioria dos trabalhos relatou limitações físicas e mecânicas do cimento de ionômero de vidro e constatou que a grande vantagem dos cimentos de ionômero de vidro convencionais em relação a outros materiais é a biocompatibilidade, que, por sua vez, não pode ser verificada nos cimento de ionômero de vidro modificados por resina.
The objective of the dentistry is the x preservation of healthy tooth structure and rebuilding the lost tissue, searching through the use of materials and restorative techniques appropriate, to prevent relapses or even appearance of new lesions of dental caries. Among these materials, those that stand out because their therapeutic nature, are glass ionomer cements (GICs). The aim of this study is conduct a systematic review of publications about the physical, mechanical and biological weapons of CIVs in order to evaluate the results found in the literature. The publications were selected from a search in database (Medline - Literature Internacional Health Sciences, BBO - Brazilian Bibliography of Dentistry and Scopus) in the period from 2000 a 2008, using the words: glass ionomer cements, properties mechanical and biocompatibility. It was noted that there was a certain standardization of the methodologies descriptions, which make easier the comparison of publications. Most of the studies reported mechanical and physical limitations of GICs and found that the major advantage of conventional glass ionomer cements comparing to other materials is biocompatibility, which could not be found in resin modified glass ionomer cements.
