The present case report describes a modification of the connective tissue graft wall technique with enamel matrix derivative applied to treat deep vertical bony defects. The technique presented uses a palatal incision to gain access to the bony defect. Deep infrabony defects affecting two maxillary central incisors associated with interdental and buccal gingival recession were treated. At 1 year after surgery, 9 and 6 mm of interdental clinical attachment level gain were seen in cases 1 and 2, respectively...

BACKGROUND/PURPOSE: Spaced primary dentition plays a critical role in the eruption of permanent teeth and the establishment of ideal occlusion. A lack of these spaces in deciduous dentition may result in disproportionate jaw and tooth sizes. Additionally, spaced primary dentition is significantly affected by ethnic factors. However, few of these studies have been conducted in Asia. The purpose of this study was to investigate the prevalence of spaced primary dentition in Taiwan. METHODS: One hundred and forty-seven 3- to 6-year-old Taiwanese children (58 girls and 89 boys) were recruited for a cross-sectional study...

In the cochlea, a high K(+) environment in the endolymph is essential for the maintenance of normal hearing function, and the transport of K(+) ions through gap junctions of the cochlear epithelium is thought to play an important role in endolymphatic homeostasis. The aim of the present study was to demonstrate the three-dimensional (3D) ultrastructure of spiral ligament root cells and interdental cells, which are located at both ends of the gap junction system of the cochlea epithelium. Serial semi-thin sections of plastic-embedded rat cochlea were mounted on glass slides, stained with uranyl acetate and lead citrate, and observed by scanning electron microscopy (SEM) using the backscattered electron (BSE) mode...

BACKGROUND: Open gingival embrasure, so called the "black triangle", is one of the unsolved dilemmas in adult dentistry. Although various techniques were introduced to improve the black triangles, the lack of reproducible experimental models has prevented the development of successful protocols to regenerate or to compensate the loss of the interdental papilla. Therefore, the objective of this study was first to develop a reliable animal model of open gingival embrasure, and then to validate a minimally invasive injection technique using the hyaluronic acid (HA) filler to augment the interdental papilla...

Intraoperative navigation is a helpful tool in complex anatomical regions or procedures. The mobility of the mandible in relation to the skull base limits the use of navigation tools on the lower jaw if the reference device is installed on the forehead. A new workflow that allows navigation-assisted sagittal split osteotomy in orthognathic surgery using a separate non-invasive mandibular registration technique has been developed. An evaluation of accuracy in different anatomical regions and with different registration techniques was performed on skull models and skulls with movable mandibles...
