Abnormalities of Teeth

define attritrion

tooth to tooth contact/ mastication

is attrition physiological

yes

once attrition affects appearance and function it becomes ---

pathological

what is an example of NORMAL attrition

flatting of mamelons

what can speed up the effects of attriton

poor diet, poor quality of enamel, grinding, premature occlusal contacts

what is a severe form of attrition

bruxism

how can you treat bruxism

occlusal interferences or an acrylic splint

define abrasion

wear due to mechanical habit

WEAR AT THE ROOT

is abrasion pathological?

yes

how does dentin respond to abrasion

by laying down secondary dentin

what can abrasion lead to

exposed dentin hypersensitivty

define demastication

attrition AND abrasion = accelerated tooth loss

example of abrasion

toothbrushing, bobby pins, etc

define erosion

chemical wear not due to bacteria

what is perimolysis an example of

erosion

define abfraction

SEVERE loss of structure near the gingiva from occlusal stressed that create tooth flexure

how would you treat abfraction (3 steps)

1. detailed diagnosis,

2. preventative measures

3. long term monitoring (fix any pain immediately)

teth arising in the first ____ days of life are neonatal teeth

30

define neonatal teeth

prematurely erupted deciduous teeth

what is the risk of neonatal teeth

if they are mobile, the baby could choke on it (you should extract it)

how would you treat neonatal teeth

extraction or retain

what is the most common neonatal teeth in order from most to least

anterior mandibular, anterior maxillary, posterior teeth

what is the ulcer caused by neonatal teeth called
