Oral Habits Flashcards
What are parafunctional habits?
Habits that are not normal and affect occlusion
In what order should you treat malocclusion?
First treat parafunctional habit, then treat occlusion
What is the correct position of the tongue?
on the palate bringing balance to all the teeth
What is the correct position of the tongue?
resting on the hard palate and back surface of upper incisors bringing balance to all the teeth
What happens with thumb sucking?
the tongue is depressed, the cheeks push towards the teeth and can cause posterior cross bite
How does self-correction occur?
tongue pressure or distal drift of primary canines into primate space
(canines usually erupt mesially)
T/F: Malocclusion can be due to skeletal problem only.
False. It can be due to dental, skeletal, or both!
How to diagnosis malocclusion and if it’s skeletal or dental?
lateral CEPH
What type of sucking response occurs with thumb sucking not related to nutrients but before 3?
a. nutritive
b. non-nutritive
c. chronic
b. non-nutritive
What type of sucking response occurs with thumb sucking needed to survive?
a. nutritive
b. non-nutritive
c. chronic
a. nutritive
What type of sucking response occurs with distortion of dent-alveolar structures and older than 3 years old?
a. nutritive
b. non-nutritive
c. chronic
c. chronic
What is the order of importance of non-nutritional sucking habit in regards to frequency, duration, and magnitude?
frequency least important
duration most important
Is thumb or pacifier more detrimental?
pacifier
because harder to remove from child
T/F: there is a benefit to an orthodontic pacifier
false
What are the potential dentoalveolar changes due to a pacifiers?
increased overjet, anterior open bite, posterior cross bite, and class II malocclusion
How many children have a non-nutritional habit @ 3 years of age?
10-40%
If the habits are maintained less than 12 months, what will the impacts on occlusion be?
no adverse effects
If the habits are maintained more than 36-48 months, what will the impacts on occlusion be?
altered occlusions such as open bites and posterior crossbites
What have thumb sucking habits been more linked to?
anterior open bites and increased overjet
What have pacifier habits been more linked to?
posterior crossbites
T/F: bottle is more demential than the breast in malocclusion
true
What could be the possible history of a patient with an anterior open bite?
- non-nutritive sucking habit of thumb (after 3 yrs of age)
- allergies, asthma, sleep disturbances
