Cells of Oxytricha fallax possessing cytotactically inherited supernumerary dorsal bristle rows can redevelop those dorsal supernumerary rows after cystment, even though supernumerary ventral cortical structures are permanently lost through cystment. Previous work has demonstrated: (1) that cystement involves a complete dedifferentiation of all ciliary structures-all cilia, basal bodies, microt...

The surgical removal of supernumerary teeth is necessary in some cases, especially before the commencement of any orthodontic or implant treatment procedure. In the mandibular supernumerary premolar, a more conservative approach is required because of the presence of complications associated with conventional surgery due to the close proximity of the said premolar to the alveolar inferior and m...

Pieces of kidney and/or lung from adult frog (Rana pipiens) when implanted under the dorsal skin of the lower arm (mid-radius/ulna level) of Ambystoma maculatum larvae, induced supernumerary limbs in over 75% of the cases. Liver was completely ineffective in inducing ability. However, liver did not lower the inducing capacity of lung in combination grafts. When the insertion hole was distal to ...

Supernumerarypremolars have been reported to occur in 0.29%of thegeneral populationand to represent about 9.1% of all supernumerary teeth. Most of the supernumerary teeth reported in the literature were detected by radiographsas most of them were unerupted or impacted.Asearch of the literature revealed not many cases of fully erupted and well aligned supernumerary premolars being reported. A ca...

Supernumerary teeth occur frequently in permanent dentition, but they are rarely found in primary dentition. Supernumerary teeth of orthodox shape and size that resemble normal dentition are called 'supplemental teeth'. Supplemental teeth are less common than supernumerary teeth and are often overlooked because of their normal shape and size.Supplemental teeth may cause esthetic problems, delay...

Dens evaginatus is a dental anomaly found predominantly in people of Mongoloid origin. Dentists practising in Western countries should also be aware of this condition because of the increasing migration of people from Asia. Supernumerary premolars are uncommon but may be found incidentally during radiographic examination of teeth with dens evaginatus. This article reports 2 cases of concomitant...

Background: Ectopic ovaries are an uncommon congenital anomaly. Supernumerary ovaries are sometimes confused with accessory ovaries, mesenteric cysts, and lymph nodes. Case presentation: We experienced two cases of ectopic ovaries. A 26-year-old woman had a supernumerary ovary of 3x2.5x2 cm mass located on the Cul-de-sac between the rectum and the uterus. A 23-year-old woman had an accessory ov...

Teeth in excess number than the normal count are called supernumerary teeth. They can be either unilateral or bilateral and single or multiple, found at any place in the dental arch, but most commonly found in the anterior maxillary region. Supernumerary teeth are commonly associated with syndromes when present in more numbers, but can be idiopathic. The present study shows a case report of a 1...
