Popis: Aim: The purpose of this study was to evaluate factors associated with the fill of interdental spaces by gingival papillae. Materials and Methods: Ninety-six adult subjects were evaluated. Papilla score (PS), tooth form/shape, interproximal contact length and gingival thickness were recorded for 672 maxillary anterior and first pre-molar interproximal sites. Statistical analyses included a non-parametric w 2 test, ANOVA, the Mixed Procedure for SAS and Pearson’s correlation coefficient (r). Results: Papilla deficiency was more frequent in older subjects (po0.05), as papilla height decreased 0.012mm with each year of increasing age (po0.05). Competent papillae (complete fill inter-dentally) were associated with: (1) crown width: length X0.87; (2) proximal contact length X2.8mm; (3) bone crest-contact point � 5mm; and (4) interproximal gingival tissue thickness X1.5mm. Gingival thickness correlated negatively with PS (r 5 � 0.37 to � 0.54) and positively with tissue height (r 50.23‐0.43). Tooth form (i.e. crown width to length ratio) correlated negatively with PS (r 5 � 0.37 to � 0.61). Other parameters failed to show any significant effects.
