Several topical and systemic factors have been reported to influence the eruption of teeth. Some of the local lesions include eruption cysts, eruption sequestra, fibrous developmental malformations and dentigerous cysts. The systemic factors include Down’s syndrome, cleidocranial dysostosis, hypothyroidism, hypopituitarism and achondroplastic dwarfism. All these lesions and factors generally in...

to report the oral findings, including dental anomalies, ectopic eruption of the maxillary permanent first molars and periodontal disease and soft tissue alterations, in a subject with apert syndrome. clinical and radiographic examination of a patient with apert syndrome, aged 21 years old, not previously submitted for orthodontic or orthognathic treatment. dental anomalies were present in a pa...

Background: Adrenal hematoma is a very rare acquired cause of neonatal hypertension. In this study, we report a case of neonatal hypertension associated with adrenal hematoma. A male neonate was immediately transferred to our neonatal intensive care unit after delivery due to meconium aspiration. He needed to be on mechanical ventilation support. During his hospital stay, hospital records showe...

The deciduous dentition of the domestic pig is comprised of 28 teeth (2 x incisors 3/3, canine 1/1, premolars 3/3, molars 0/0). The timing and sequence of deciduous dental eruption were determined from oral exams on 233 Yorkshire piglets from 0 to 5 wk of age. Eruption occurred sooner in gilts for all molariform premolars (p(3), p(4), and p(4), P < 0.01) and first incisor, i(1) (P = 0.004). Bir...

BACKGROUND To determine the mean eruption time of permanent teeth of Pakistani children and to evaluate the effects of gender, type of schools, height, weight and body mass index on it. METHODS This cross sectional study was conducted from September 2007 to April 2008. 4370 children of 'just erupted' teeth were obtained from 102 randomly selected schools from 18 towns of Karachi, using system...

Ectopic eruption is a concept including those clinical cases in which teeth show abnormal eruption pattern and erupt ectopically, in an incorrect position. This abnormality has been pointed out in the literature for the fi rst permanent molars, mainly the maxillary ones. There is no specifi c etiological factor for this abnormality in the fi rst permanent molar, but different factors are report...

PURPOSE The purpose of this study was to assess the effectiveness of rapid maxillary expansion (RME) vs simply monitoring the eruption of permanent maxillary incisors following the surgical removal of obstacles to their eruption (supernumerary teeth, odontomas). METHODS Following surgical removal of the obstacles to incisor eruption (T1), 62 patients were randomly assigned to either the group...

Following the installation of the Ocean Observatories Initiative cabled array, the 2015 eruption of Axial Seamount, Juan de Fuca ridge, became the first submarine eruption to be captured in real time by seafloor seismic and acoustic instruments. This eruption also marked the first instance where the entire eruption cycle of a submarine volcano, from the previous eruption in 2011 to the end of t...

In ungulates, a set of deciduous teeth is replaced by a set of permanent teeth during their first 2 years of life. Little is known about factors causing variation in timing of tooth eruption, but overall size, condition or mineral deficiencies may play a role. The pattern of incisor (I) and canine (C) eruption was investigated in 2241 yearlings from five populations of red deer Cervus elaphus i...

a 25-year-old man was admitted in hospital due to right side hemopneumothorax secondary to car accident. a chest tube was inserted. during the hospitalization days, chest ct scan revealed a 3cmx3 cm oval-shaped density located in the right upper lobe. since he was in a good general condition, he was discharged from hospital after removal of chest tube and a follow-up chest ct-scan was recommend...
