Sorularke Flashcards
What is maxilla, what is mandible?
The maxilla is the upper jaw and the mandibula is the lower. Maxillary is stationary. Mandibula is moveable.
When do permanent teeth erupt and when do the eruption stop.
Permanent teeth at 6 and it stops around 17-21.
The shapes of dental arches.
Primary: Both semicircular
Permanent:
Upper is semi-elliptical.
Downer is parabolic
What is deciduous?
The primary teeth. The teeth before the eruption.
What is succedaneous?
What is non-succedaneous?
1-The teeth that will erupt and take the place of primary teeth.
2- The teeth which are not replaced by another kind of teeth. Permanent molars.
Main parts of the root:
Crown
Root
Separated by cervical line.
What is proximal surface?
Mesial Distal
5 Grades Of Attrition:
1- Enamel wears down.
2- Dentin is exposed in the cusps in incisal edges.
3- Dentin is exposed in occlusal surfaces surrounded by enamel.
4- The process reaches pulp chambers and pulp chamber can maybe get inflamed.
5- The tooth wears down to intergingival margin.
Where can we see attrition?
In the palatal surface of the upper teeth and the facial surfcase of lower teeth.
Where can we see attrition?
In the palatal surface of the upper teeth and the facial surfcase of lower teeth.
What causes abrasion?
Mechanical proccesses. Overbrushing, flossing, use of toothpicks. Working in a polluted area.
Which teeth abrasion affects the most
Canines, premolars, the buccal surface of upper first molars.
Which teeth abrasion affects the most
Canines, premolars, the buccal surface of upper first molars.
Which surfaces erosion affect the most?
Occlusional and palatal.
Enamel made by
ameloblast.
Dentine made by
odontoblast.
Tooth identifiers- crown
1- Angular characteristics, distoincisal edge mesioincisial edge 2- Curvature of the cervical line 3- Arch characteristics Mesiovestubular distovestubular 4- Cervical contour 5- Inclination of the cusps.
