Two infrabony defects (i.e. defects in tooth supporting bone that extend into the body of the bone) in different sites in the same individual were treated surgically. Tissue regeneration was incorporated into the surgical procedures using a different material in each site (oxidized cellulose mesh and bioglass). The post surgical radiographic appearance showed increasing calcification in both si...

OBJECTIVE The aim of this study was to investigate the association between dental and skeletal maturity. STUDY DESIGN Digital panoramic radiographs and lateral skull cephalograms of 302 patients (134 boys and 168 girls, ranging from 8 to 16 years of age) were examined. Dental maturity was assessed by calcification stages of the mandibular canines, first and second premolars, and second molars...

The progressive character of tooth formation records aspects of mammalian life history, diet, seasonal behavior and climate. Tooth mineralization occurs in two stages: secretion and maturation, which overlap to some degree. Despite decades of study, the spatial and temporal pattern of elemental incorporation during enamel mineralization remains poorly characterized. Here we use synchrotron X-ra...

Normative standards are provided for permanent tooth mineralization stages for blacks and whites of the middle southern United States. The data cover tooth development from 3.5 to 13 years of age. Females develop more rapidly than males, and blacks are nearly twice as sexually dimorphic (7.2%) as whites (3.7%). Within each sex, blacks achieve mineralization stages significantly earlier, by abou...

Introduction: Dilated odontoma is the most severe form of a dens invaginatus, which rare dental malformation resulting from an invagination enamel organ into papilla before calcification occurs. Observation: A healthy 7-years-old girl was referred to oral surgery department remove impacted causing delayed eruption right mandibular lateral incisor (tooth 42). The patient painless and lingual oss...

Noninflammatory massive calcification in the unilateral adrenal gland was confirmed in three cases, and infarction and extensive hemorrhage were prominent in etiology as usual cases in the literature. Infraction was also responsible for local ized calcification and ossification in a functioning cortical adenoma which had myelolipomatous lesions as a usual complication. The first description of ...

Conclusions LNMAC histopathology reveals a necrotic core (amorphous eosinophilic material) and surrounding inflammatory rim (macrophage and lymphocytic infiltration) with zonal calcification. By MRI this zone of cellular inflammation and edema manifests as the zone of peripheral hyperenhancement on the PSIR, HASTE, and IR TURBOFLASH sequences. Most benign or malignant cardiac tumors show high T...

Zygomatico coronoid ankylosis is a rare type of extra articular ankylosis. The most common cause is Jacobs Disease, which is due to osteochondroma of the coronoid process. In this paper we present a case where in the zygomatico-coronoid ankylosis is due to heterotopic ossification, secondary to surgical trauma from previous operations. A literature search does not show any similar reported case...

trauma to primary teeth can lead to devastating sequels in development of permanent successors. the disturbance may range from enamel hypoplasia and/or hypo-calcification to arrest of dental bud development. crown dilaceration of permanent teeth is one of the consequences of trauma to deciduous teeth mainly due to intrusion or avulsion. this report presents a mandibular central incisor with dil...
