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.
3 main parts of the mandible
Ramus, angle and body
What is the middle ridge in the mandible?
Mandibular symphysis. Which marks the line where two bones were united in the early life.
What is mandibular protuberance?
It is the division of the middle ridge inferiorly. It forms
the mental tubercule in each side.
Explain the alveolar process of the mandible.
The alveolar process exists in the superior part of the body of the mandible which houses the teeth. The teeth have a specialized kind of fibers joint which is called gomphosis. It joins the root of the teeth and the socket of the bone either in the maxilla or mandibula.
What is mandibular foramen.
The mandibular foramen are the visible holes in mandible. It is found in the lower border of the alveolar part and the upper border of the base part. It is between two premolars. The inferior alveolar nerve and lingual nerve pass through it. The nerves sit in the mylohyoid groove.
What structure is on the Inner surface of the mental region
Superior mental spine and inferior mental spine
