This study aimed to discuss some inborn and acquired changes in the oral cavity young children under three years of age. Based on current literature, eruption cyst, Riga-Fede disease, natal neonatal teeth, congenital epulis, Epstein pearls, Bohn’s nodules, gingival cyst newborns have been described. The symptoms, clinical presentation, histological features these changes, their epidemiology, pr...

intraosseous movement of an unerupted tooth across the midline of the jaw is known as dental transmigration. this infrequent event is mostly found in the mandibular canines. there are four new cases of mandibular canine transmigration presented here. the literature on this anomalous phenomenon is also reviewed.

introduction multiple dentigerous cysts are rare and mostly associated with syndromes. case presentation the present case report is unique, as the dentigerous cysts enclosed the lateral incisor, canine, first and second premolars of the mandible and were accompanied by a complex odontoma, instead of first mandibular molar. conclusions multiple unilateral nosyndromic dentigerous cysts with compl...

this report presents a rare case of bi-rooted primary maxillary canines. a 6-year-old girl presented at the department of pediatric dentistry, faculty of dentistry, mashhad university of medical sciences, iran, with the chief complaint of pain in the lower right quadrant of her dentition. radiographic examination revealed bifurcation of primary maxillary canine roots. this report discusses the ...

objective : the aim of this study was to assess the amount of interdental bone in posterior areas of the mandible for placing orthodontic mini-implants to provide and control anchorage in orthodontic treatment. materials and methods : the amount of interdental bone in areas between the second premolars and first molars, first and second molars on the right and left sides of the mandible were de...

The most important phase of crown growth in the primary dentition is completed during the foetal period. Lower central incisors often show the cervical edge of the enamel and the beginning of root growth at term. Disturbances of foetal dental growth are rarely apparent; most of the hypoplasias seen on the teeth arise during the neonatal period (Massler and Schour, 1946). The commonest disturban...

In 2013 we presented a model for identifying nursing behavior from primate teeth based on rapid postnatal concentration changes in the non-essential trace element barium. Here leverage permanent neonatal (birth) line enamel of several dozen M1 cusps to compare pre- and trends barium, zinc, strontium, oxygen, as each is believed evince developmental patterning. Barium zinc are most consistent bi...

sepsis is the most common cause of neonatal mortality. as per national neonatal-perinatal database (nnpd), 2002-2003, the incidence of neonatal sepsis in india was 30 per 1000 live births. signs and symptoms of sepsis are nonspecific; therefore empirical antimicrobial therapy is promptly initiated after obtaining appropriate cultures. the early manifestations of neonatal sepsis are vague and il...

background: neonatal infections are one of the major causes of death in iran. since identifying the risk factors, types, site, bacterial causes, and case fatality rate of an infection can be effective in selecting preventive and therapeutic methods, and appropriate supportive measures, this study aimed to investigate the aforementioned factors in the neonatal intensive care unit (nicu) of ghaem...

abstract : dens invagination (di) is a developmental abnormality of teeth which frequently results in a complex internal anatomy of the root canal system. di type 3 is an anomaly characterized by infolding of enamel and dentin extending into the root apex. this may present difficulties when forming a diagnosis and treatment plan. many treatment modalities have been presented in case reports for...
