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 ...

This study was divided into 3 phases. The 1st phase was the experiment in seven cadaver skulls to compare force from 2 techniques of weight load; interdental wiring and interdental wiring together with dental acrylic, with 1, 2 and 3 kilogram bar for 10 minutes. The evaluation was done by measuring the gap of the fracture line in a lateral radiograph. The force was calculated from the gap accor...

In recent years, clinician and dentist's esthetic demand in dentistry have increased rapidly, driven by an enhanced awareness of beauty and esthetics. The ultimate goal in modern restorative dentistry is to achieve "white" and "pink" esthetics in esthetically important zones. "White esthetics" is the natural dentition or the restoration of dental hard tissues with suitable materials. "Pink esth...

Oligodontia is defined as a congenital tooth agenesis with the absence of six or more permanent teeth. This clinical report describes a patient with non-syndromic partial oligodontia, with retained deciduous teeth and the absence of 16 permanent teeth. Anterior esthetic problems were caused by interarch tooth size discrepancy, interdental space, aberrant tooth dimensions, and the absence of cen...

background: Daily oral biofilm disruption by clients is recommended by oral health professionals to prevent oral diseases and to maintain optimal oral and overall health. since periodontal diseases and caries are prevalent interproximally, the adjunctive use of interdental aids is highly recommended. objectives: to evaluate the effectiveness of interdental brushing as an adjunct to toothbrushin...

Two hundred forty interdental papilla sites in 20 healthy patients were investigated. Interdental papilla heights of maxillary anterior teeth were measured from the gingival zenith, along with clinical crown lengths. Percentages of papilla height to crown length were computed and defined as papilla proportion, mesial papilla proportion (MPP), and distal papilla proportion (DPP). Mean interdenta...

BACKGROUND The majority of caries lesions in adults occur on the proximal tooth surfaces of the posterior teeth. A comprehensive study of the composition of the oral microbiota is fundamental for a better understanding of the etiology of interdental caries. METHODS Twenty-five caries-free subjects (20-35 years old) were enrolled in the study. The interdental biofilm of four interdental sites ...

Objective : The aim of this study was to assess the amount of interdental bone in posterior areas of the mandible for placing orthodontic mini-implants to provide and control anchorage in orthodontic treatment. Materials and Methods : The amount of interdental bone in areas between the second premolars and first molars, first and second molars on the right and left sides of the mandible were de...

The auditory teeth in the spiral limbus of the cochlear duct are located under the limbal portion of the tectorial membrane and separated by furrows lodging the interdental cells. In this study, the shape, arrangement and distribution of the auditory teeth in the cochlear duct of adult mice were examined by scanning electron microscopy after removing the tectorial membrane and the interdental c...
