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...

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...

tion, the differential diagnosis may also include a number of other conditions such as lichen sclerosus, psoriasis, discoid lupus, graft-vs-host disease, and secondary syphilis. The intention of our article was to provide a clear and concise introduction to lichenoid drug eruption, rather than dwell on the subtleties of the differential diagnosis. We agree that in cases in which the clinical di...

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...

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...

and painful ; the gums were spongy and tender. Two or three teeth in the lower jaw were also decayed, but not painful. It appears that he has suffered from tooth-ache more or less for the last ten years, and that he had a molar tooth extracted some time ago ; he has had facial neuralgia, but no eruption previously.. He is otherwise in fair health, and is temperate. The eruption extended from th...

Precise and direct dating of the Minoan eruption of Santorini (Thera) in Greece, a global Bronze Age time marker, has been made possible by the unique find of an olive tree, buried alive in life position by the tephra (pumice and ashes) on Santorini. We applied so-called radiocarbon wiggle-matching to a carbon-14 sequence of tree-ring segments to constrain the eruption date to the range 1627-16...
