vital pulp therapy (vpt) of permanent mature teeth is continuously ascertaining to be a more reliable endodontic treatment. the purpose of this case report was to describe successful vpt of a mature mandibular left first molar with concurrent hyperplastic pulpitis, internal root resorption and periradicular periodontitis in a 35-year-old male patient. after complete caries removal and access ca...

Background & Aims: Calcifying nanoparticles are different forms of calcium and phosphate in sediments. Recent evidence suggests that calcifying nanoparticles (CNPs) are probably selfreplicating. Several diseases are linked to nano-bacteria including kidney stones, gallbladder stone, cardiovascular plaques, oral–dental plaque, many cancers, and autoimmune diseases. The aim of this study was to a...

Calcifying fibrous tumors are rarely seen and affect mostly children and young adults. A 21-year-old man presented with multiple palpable masses in the area from the right inguinal region to the anteromedial thigh. We performed a diagnostic excisional biopsy. Histopathologically, it was composed of fibroblasts, psammoma bodies, dystrophic calcifications and foci of mononuclear inflammatory cell...

Three hundred and thirty six forensic necropsy specimens of large bowel were examined in order to identify subject related variables that independently predicted the following adenoma characteristics: presence, size (largest), multiplicity and high grade dysplasia. The variables were age, gender, body mass index, race (European origin versus Maori/Polynesian) and presence of hyperplastic (metap...

the aim of this case report was to present a case of multiple idiopathic apical root resorption which is a rare condition in a 17-year-old adult male. external root resorption of the permanent teeth is a multifactorial process. well-recognized causes of apical root resorption in permanent teeth include orthodontic therapy, trauma, periapical or periodontal inflammation, tumors, cysts, occlusal ...

Complex human tissues harbor stem cells and/or precursor cells, which are responsible for tissue development or regeneration. Recently, dental tissues such as periodontal ligament (PDL), dental papilla or dental follicle have been identified as easily accessible sources of undifferentiated cells. Dental precursor cells are attractive for usage in regenerative dentistry, like for example regener...

The mechanism of root formation and tooth eruption is a complex process which is not fully understood. Prior to a tooth emerging into the oral cavity, root genesis is initiated by derivatives of the enamel organ. The dental follicle mediates an eruption pathway allowing for movement of the developing tooth in a coronal direction. As the tooth moves towards the oral cavity, root formation occurs...

Amelogenesis imperfecta (AI) is a genetically and clinically heterogeneous group of inherited dental enamel defects. Commonly described as an isolated trait, it may be observed concomitantly with other orodental and/or systemic features such as nephrocalcinosis in Enamel Renal Syndrome (ERS, MIM#204690), or gingival hyperplasia in Amelogenesis Imperfecta and Gingival Fibromatosis Syndrome (AIGF...

Foreign body aspiration or ingestion is an uncommon potential complication during orthodontic dentistry, and it can produce a medical emergency. Obstruction of the airways be life-threatening, delayed recognition management result in pulmonary complications such as recurrent pneumonia. Dental treatment has been identified important cause misplacement foreign bodies airway. Objects used are main...
