OBJECTIVE Orthodontic diagnosis and treatment planning for growing children must involve growth prediction, especially in the treatment of skeletal problems. Studies have shown that a strong association exists between skeletal maturity and dental calcification stages. The present study was therefore taken up to provide a simple and practical method for assessing skeletal maturity using a dental...

The dental pulp is characterized as a connective tissue and as such it is not considered an external tissue, yet its exposure to external stimuli is constant. This is due to a number of factors including the permeability of attrited or disrupted enamel as well as that of physiologic dentin and cementum. The pulp is extraordinarily sensitive to its external environment. Once thought to be a vest...

Spinal cord injury (SCI) often leads to persistent functional deficits due to the loss of neurons and glia and to limited axonal regeneration after such injury. Recently, three independent groups have reported marked recovery of hindlimb locomotor function after the transplantation of human adult dental pulp stem cells (DPSCs) and stem cells from human exfoliated deciduous teeth (SHEDs) into ra...

Streptococcus mutans is a major pathogen of dental caries. Collagen-binding proteins (CBPs) (approximately 120 kDa), termed Cnm and Cbm, are regarded as important cell surface antigens related to the adherence of S. mutans to collagenous tissue. Furthermore, CBP-positive S. mutans strains are associated with various systemic diseases involving bacteremia, such as infective endocarditis. Endodon...

Derived from neural crests, the mature pulp is due to the proliferation and condensation of apical cells implicated in root lengthening. Adult cells are bound together by intercellular junctions (desmosomes and gap junctions), forming a network. They are further transported to the crown. Root lengthening is associated to tooth eruption and to vertical sliding. Composed by type I and III collage...

conclusions the relationship between cac found on dental panoramic radiographs and two cva risk factors--hypertension and mi-- was significant. therefore, it seems that detection of cac on panoramic images of dental patients must be considered by dentists. results among 200 studied samples, 22 of the patients (11%) had carotid artery calcification on the dental panoramic radiograph. in total, 5...

A retrospective survey was designed to identify diagnostic subgroups and clinical factors associated with odontogenic pain and discomfort in dental urgency patients. A consecutive sample of 1,765 patients seeking treatment for dental pain at the Urgency Service of the Dental School of the Federal University of Goiás, Brazil, was selected. Inclusion criteria were pulpal or periapical pain that o...

Little is known about the histogenesis of the odontogenic myxoma (OM). Dental pulp stem cells could be candidate precursors of OM because both OM and the dental pulp share the same embryological origin: the dental papilla. For the purpose of comparing OM and stem cells, this study analyzed the expression of two proteins related to OM invasiveness (MMP-2 and hyaluronic acid) in human immature de...

BACKGROUND Pulp stones (PS) are discrete calcified masses found in the dental pulp, in the pulp tissue or become attached to or embedded into the dentine. The formation of pulp stones is still something of an enigma, leading to existence of some epidemiological gaps. AIM To determine the prevalence and distribution of pulp stones in posterior tooth group by using panoramic radiograph. MATER...

A patient with pseudohypoparathyroidism is presented. The phenotypic appearance, known as Albright heredity osteodystrophy includes: short stature, round face, brachydactylia, and ectopic calcifications in the soft tissues. Dental manifestations reported in the literature are enamel hypoplasia, hypodontia, malformed roots, enlarged pulp chambers, microdontia, and pulp calcifications. Additional...
