چکیده

AIM The purpose of this study was to evaluate factors associated with the fill of inter-dental 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 chi(2) test, anova, the Mixed Procedure for SAS and Pearson's correlation coefficient (r). RESULTS Papilla deficiency was more frequent in older subjects (p<0.05), as papilla height decreased 0.012 mm with each year of increasing age (p<0.05). Competent papillae (complete fill inter-dentally) were associated with: (1) crown width: length >or=0.87; (2) proximal contact length >or=2.8 mm; (3) bone crest-contact point or=1.5 mm. Gingival thickness correlated negatively with PS (r=-0.37 to -0.54) and positively with tissue height (r=0.23-0.43). Tooth form (i.e. crown width to length ratio) correlated negatively with PS (r=-0.37 to -0.61). Other parameters failed to show any significant effects. CONCLUSIONS Gingival papilla appearance was associated significantly with subject age, tooth form/shape, proximal contact length, crestal bone height and interproximal gingival thickness.

Quantitative measures of gingival recession and the influence of gender, race, and attrition

BACKGROUND Gingival recession in dentitions with otherwise healthy periodontium is a common occurrence in adults. Recession is clinically measured using a periodontal probe to the nearest millimeter. The aim of this study is to establish quantitative measures of recession, the clinical crown height, and a new measure the gingival margin-papillae measurement. The latter is seen as the shortest a...

Tongue structure in the long-eared hedgehog (Hemiechinus auritus): A scanning electron microscopic study

The aim of this study was to investigate the dorsal surface of the long-eared hedgehog tongue using scanning electron microscopy. The tongue of the long-eared hedgehog is rectangular-shaped with an elongated body and a widened root and a marked deep median groove can be seen on its dorsal surface. A characteristic feature of the lingual root is presence of two huge laterally situated folds. The...

An analysis on the factors responsible for relative position of interproximal papilla in healthy subjects

PURPOSE This study examined the factors that can be associated with the appearance of the interproximal papilla. METHODS One hundred and forty-seven healthy interproximal papillae between the maxillary central incisors were examined. For each subject, a digital photograph and periapical radiograph of the interdental embrasure were taken using a 1-mm grid metal piece. The following parameters ...
