Over All

The muscle involved in incisor clenching is the
Lateral pterygoid
The deciduous teeth erupt generally in a
Anterior - posterior sequence
The most common permanent teeth eruption in maxilla is
(6-1)-2-4-3-5-7-8
The difference between mesiodistal diameter width between premolars and deciduous molars is referred as
Leeway space
Curve of Spee is in a
Saggital plane
In a normal dentition, teeth are placed __________ degrees to the horizontal plane
15
Balanced occlusion is given by
Thielemann’s formula. Explanation  Balanced occlusion is ( condylar guidance*incisial guidance)/ ( curve of Spee* cusp height* plane of occlusion)
Mesiodistal inclination of the teeth is lowest with
Mandibular canine. The inclination is 0 degrees and maximum inclination is seen with maxillary canine and about 17 degrees. Similarly the minimum faciolingual inclination is about 5 degrees with maxillary first premolar and 28 degrees in maxillary central incisors.
The total number of possible occlusal contacts are
198
The process of swallowing requires a coordination of at least
20 muscles
The presence of overjet in molars prevents
Cheek biting
The supporting cusps are
Lingual cusp of maxilla and buccal cusp of mandible teeth
Multiple working side contacts are seen as a part of
Group function
The areas of contact that a supporting cusp makes with opposing teeth is
Centric stop
A phasic jaw-closing reflex is often evoked by a tap to __________ and denotes _____________.
