Stálé první dolní moláry jsou zuby, které ve většinových případech mají v anatomických korunkách pět hrbolků a kořenovém systému dva kořeny. Nálezy šesti velmi řídké spíše raritní, zvláště u evropské populace. Tato morfologická odlišnost je typická populace australských Aboriginů.

objective: attempts to treat class ii malocclusions without extraction in non-compliant patients have led to utilization of intraoral molar distalizing appliances. the purpose of this study was to investigate dental and skeletal effects of bonded molar distalizer (bmd) which is a simple molar distalizing appliance. materials and methods: sixteen patients (12 girls, four boys) with bilateral hal...

BACKGROUND First, first permanent molars (FPMs) of poor prognosis are often planned for extraction at an 'ideal time' so that second permanent molars (SPMs) erupt favourably to replace them. However for lower FPM extractions, timing is not an accurate predictor of success. OBJECTIVE The aim of this study was to identify additional radiographic factors that could better predict the degree of s...

An odontome is a slow growing and non-aggressive odonotogenic tumor composed of enamel,dentin,cementum and pulp tissue.complax odontome comprise of an unorganized mass of odonotogenic tissues,morphologically not resembling the normal teeth.in this report,a case of rare odontoma in a ten-years-old boy that caused dalayed eruption of a maxillary right farst permanent molar,buccal expansion of the...

The purpose of this clinical report was to introduce a simple and effective way of performing ectopic eruption treatment utilizing a triangular wedging spring. This consists of 3 helical loops in a triangular shape with 0.018-inch Australian wire. The middle helical loop is made for wedging spring action, while the other 2 helical loops are action arms inserted between the second primary molar ...
