excessive gingival display can affect the total esthetics of a smile, becoming the focus instead of the frame of the smile. This can be the result of passive eruption of the gingival complex as the teeth erupt.1,2 the condition of delayed or altered passive eruption exists when the gingival complex remains positioned coronal to the cementoenamel junction with the attachment on the enamel instea...

BACKGROUND Hyperdontia is a disorder of odontogenesis characterised by excess teeth. Many complications can be associated with supernumerary teeth, such as crowding, tooth displacement, diastema, deep caries, retention or impaction, delayed eruption or ectopic eruption of adjacent teeth, aesthetic problems, neuralgic manifestations, root resorption of adjacent teeth, and dentigerous cyst format...

Mesiodentes are the most common supernumerary teeth, occurring in 0.15% to 1.9% of the population. Given this high frequency, the general dentist should be knowledgeable about the signs and symptoms of mesiodentes and appropriate treatment. The cause of mesiodentes is not fully understood, although proliferation of the dental lamina and genetic factors have been implicated. Mesiodentes can caus...

Abstract Forecasts of eruption are uncertain. The uncertainty is amplified when volcanoes reawaken after several generations in repose, because direct evidence previous behaviour rarely available. It fosters scepticism about warnings volcanic activity and may compromise the success emergency procedures. quality forecasts has improved over past 50 years, owing mainly to a growing sophistication ...

introdouction:tooth eruption is recognized as an important aspect of human growth and development. it can be influenced by a number of factors, and it may reflect the general development of a child’s body. the purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the city ...

Pseudohypoparathyroidism (PHP) is an inherited metabolic disorder characterized by end-organ resistance to the action of PTH (Parathyroid Hormone). There are four types of PHPs namely Ia, Ib, Ic and II. PHP Ia is associated with a constellation of clinical features referred to as Albright’s Hereditary Osteodystrophy (AHO). The oral manifestation of AHO found in the literature includes aplasia a...

F ollowing extraction of a natal or neonatal tooth, continued growth of the dental papilla may occur and a tooth-like form may develop.'^ This report describes an atypical tooth form (probably the result of continued growth of the retained dental papilla) that abscessed and may have caused delayed eruption of the adjacent primary lateral incisor. A 13-month-old white male presented to the autho...
