In the universal system of notation, the permanent maxillary premolars are designated by a number. The right permanent maxillary first premolar is known as "5", and the left one is known as "12". In the Palmer notation, a number is used in conjunction with a symbol designating in which quadrant the tooth is found. For this tooth, the left and ...
The lower premolars and the upper second premolar usually have one root. The upper first usually has two roots, but can have just one root, notably in Sinodonts, and can sometimes have three roots. [7] [8] Premolars are unique to the permanent dentition. Premolars are referred to as bicuspid (has two main cusps), a buccal and a palatal/lingual ...
The upper and lower central incisors are shed at age six to seven years. The upper and lower lateral incisors are shed at seven to eight years. The upper canines are shed at ten to twelve years. The lower canines are shed at nine to twelve years. The upper and lower first molars are shed at nine to eleven years. The upper and lower second ...
Pendulum is an orthodontic appliance, developed by James J. Hilgers in 1992, [1] that use forces to distalize the upper 1st molars to create space for eruption of impacted teeth or allowing correction of Class 2 malocclusion. This appliance is a fixed type of distalizing appliance that does not depend on the compliance of each patient to work.
The most likely causative tooth is the maxillary canine or maxillary first premolar. [1] This occurs when pus (e.g. from a periapical abscess), perforates the buccal cortical plate of the maxilla above the level of attachment of the levator anguli oris muscle. This is more likely if the tooth root is long (the maxillary canine has the longest ...
Only multirooted teeth have furcation. Therefore, upper first premolar, maxillary and mandibular molars may be involved. Upper premolars have one buccal and one palatal root. Maxillary molars have three roots, a mesio-buccal root, disto-buccal root and a palatal root. Mandibular molars have one mesial and one distal root, and so.
