INTRODUCTION To obtain sufficient stability of implants, the thickness of the soft tissue and the cortical bone in the placement site must be considered. However, the literature contains few anatomical studies of orthodontic implants. METHODS To measure soft-tissue and cortical-bone thicknesses, maxillae from 23 Korean cadavers were decalcified, and buccopalatal cross-sectional specimens were...

abstract background and aims. the aim of this study was to evalute the effect of double pedicle graft (dpg) with and without plasma rich in growth factor (prgf) in the treatment of miller's cl i and ii gingival recessions. materials and methods. thirty two bilateral buccal gingival miller’s cl i and ii recessions were selected. sixteen of the recessions were treated with dpg and prgf (test grou...

PURPOSE To analyze the dimensions of the embrasure space between the maxillary central incisors as potential factors influencing interdental papilla fill and height. METHODS The embrasure dimensions between the maxillary central incisors of 100 subjects (40 females/60 males) were assessed with clinical, study model, and radiographic examinations. Variables of the complete and deficient papill...

Salt taste signals from the rat anterior tongue are probably transduced via epithelial sodium channels (ENaCs) residing in the apical cellular pole of taste cells. The signals are blocked by mucosal amiloride in low microM concentrations. In contrast, the rat vallate papilla does not contribute to amiloride-blockable salt taste. Two approaches were used to probe for the three subunits of ENaC i...

As reptiles are situated phylogenetically between the amphibians and the mammals, they exhibit considerable variation in the structure of their tongues. The present study, one of a series of studies on reptile tongues, aims to demonstrate the three-dimensional structure of the dorsal lingual surface of a turtle, the Japanese terrapin Clemmys japonica, and to clarify the ultrastructural features...

The structure and innervation of the papilla incisiva (papilla palatina) of the shrew, Sorex unguiculatus were studied by light and electron microscopy. The papillary region of the shrew consists of the papilla proper and two epithelial processes. The main part of the papilla, with the epithelial processes, lies anterior to the incisors and is thus in the vestibulum oris. The papilla is compose...
