This study highlights the dynamic nature of the mesenchymal cells during tooth development from the bud to the bell stage. Condensing mesenchymal cells, labelled on either side of the developing tooth bud, move toward the presumptive roots forming an arc of cells under the dental papilla. These labelled cells take part in formation of the dental follicle, which contributes to both the tooth and...

Recently, numerous types of human dental derived‐mesenchymal stem cells (MSCs) have been isolated and characterized, including dental pulp stem cells, stem cells from exfoliated deciduous teeth, periodontal liga‐ ment stem cells, dental follicle progenitor cells, alveolar bone‐derived MSCs, stem cells from apical papilla, tooth germ progenitor cells, and gin‐ gi...

A new technical tip for the improvement of the arthroscopic treatment of symptomatic calcifying tendinitis is described. Arthroscopic excision of calcifying tendonitis may result with multiple minute calcific debris in the subacromial bursa, causing severe post operative pain due to chemical irritation of the bursa. We suggest the use of a bladeless shaver barrel as a "Hoover" (vacuum cleaner) ...

Encrusted cystitis is a subtype of chronic cystitis characterized by multiple calcifications in the form of plaques located in the interstitium of the urinary bladder mucosa and frequently associated with mucosal ulcers. It is a very rare disease of controversial etiology. Our transmission electron microscopy of the calcified plaques of encrusted cystitis has revealed that the smallest formed p...

Advances have been made in identifying dental stem cells and their differentiation potential. Five different types of dental stem cells have been isolated from dental soft tissues: dental pulp, apical papilla, dental follicle and periodontal ligament. The characteristic features of these cells have been explored. They express various arrays of biomarkers including those specific for mesenchymal...

INTRODUCTION Tuberous sclerosis (TS) is an autosomal dominant neuro-cutaneous syndrome characterized by multiple hamartomas in various organs, especially on skin and central nervous system. The most common features of TS include facial angiofibromas, hypomelanotic cutaneous macules, shagreen patches in the lumbar area, cerebral cortical tubers, sub-ependymal nodules, sub-ependymal giant cell as...

Root canal therapy (RCT) is a common and successful treatment for irreversible pulpitis due to carious pulp exposure in mature permanent teeth. However, it is often an expensive procedure, may require multiple appointments, and requires a high level of training and clinical skill, specifically in molars. Uninsured patients, low-income patients, and patients with limited access to specialist car...
