Electron microprobe analysis in guided tissue regeneration: a case report.

Objectives Several procedures have been advocated as regenerative procedures in periodontology, but one of the most widely used techniques up to now is guided tissue regeneration (GTR). Likewise, different assessment methods based on clinical, radiographic or histological measurements have been proposed for the evaluation of these regenerative procedures. However, none of the methods used for human material incorporates quantitative X-ray microanalysis to assess the degree of mineralization of the regenerated periodontal hard tissues. The objective of this report was to evaluate, using quantitative X-ray microprobe analysis, the newly-formed hard tissue in a periodontal infrabony defect.
