Root formation of an autotransplanted tooth
Dental Traumatology, 2009Abstract – Traumatic injuries with loss of anterior teeth occur more frequently in children. Treatment of the dental trauma is complex and requires a comprehensive and accurate diagnostic and treatment plan. It is also important to consider the biological, functional, esthetic, and economic aspects. The purpose of this article is to show a case report

Restoration of the root canal treated tooth [PDF]
British Dental Journal, 2015 When considering endodontically treated teeth, the quality of the restoration is important from the outset. It sheds light into possible causes of pulp necrosis or failure of endodontic treatment and influences the outcome of future endodontic treatment.

External cervical tooth root resorption
Stomatologiya, 2022External cervical tooth root resorption is one of the most aggressive types of pathological resorption. Due to the uncontrolled growth of resorptive tissue, irreversible loss of dentin and cement occurs. To date, there is no common position regarding the etiological factor and pathogenesis of invasive cervical resorption.

Nasal Displacement of a Tooth Root in a Dog [PDF]
Journal of Veterinary Dentistry, 2004 A ten-year-old miniature Dachshund dog was presented for chronic paroxysmal sneezing and unilateral nasal discharge. Extraction of the maxillary right fourth premolar tooth had been performed 2-weeks prior to the onset of clinical signs. Multiple diagnostic modalities were used to confirm the diagnosis and determine that the etiology was a nasally ...

The mineral solubility of human tooth roots
Archives of Oral Biology, 1987Whole roots of molars that had never been exposed to the mouth were exposed to calcium and phosphate-containing buffer solutions with discrete values of pIOHA [i.e. -log(a10Ca2+ X a6PO4(3-) X a2OH-)] at various pH. From densitometric measurements on contact-microradiographs of transverse sections of the roots the rate of demineralization (Vdem) was ...

IEEE Transactions on Plasma Science, 2011
Using the plasma generated inside the root canal rather than the afterglow of the plasma will significantly improve the inactivation efficiency. In this paper, images of three kinds of atmospheric-pressure low-temperature plasma devices driven by different power supplies in the tooth root canal are reported. The images of an R-needle device driven by a

Patterning of Molar Tooth Roots in Mammals
Journal of Oral Biosciences, 2009Abstract Tooth morphogenesis is regulated by reciprocal interactions between the dental epithelium and odontogenic mesenchyme. As tooth roots are fundamental structures of the tooth support system, the morphology and functions of the roots are very important.

Tissue Engineering of Tooth Crown, Root, and Periodontium
Tissue Engineering, 2006Tissue engineering of teeth requires the coordinated formation of correctly shaped crowns, roots, and periodontal ligament. Previous studies have shown that the dental mesenchyme controls crown morphogenesis and epithelial histogenesis during tooth development in vivo, but little is known about the inductive potential of dissociated mesenchymal cells ...

The tooth root within the maxillary sinus*
Australian Dental Journal, 1974Abstract— Histological observations in three cases of tooth root displacement to the maxillary sinus show that under certain conditions the root may be accepted by the tissues. General and local factors in the defenco mechanism and the existence or otherwise of periapical pathosis must be considered in determining the treatment.
