|
What are the effects of the terminal step on the first permanent molar? |
First molar erupts directly into proper occlusion |
|
|
What is the terminal step? |
Distal surface of lower primary molar is mesial to that of the upper molar forming a mesial step |
|
|
What is the terminal plane? |
Distal surfaces of upper and lower primary molars are on the same vertical plane |
|
|
What is the effect of the terminal plan of first permanent molars? |
First permanent molars erupts end to end |
|
|
What is the effect of no primate spaces? |
There is a late mesial shift of permanent mandibular molar into proper occlusion, following exfoliation of second primary molar |
|
|
What is the effect of having primary spaces? |
There is an early mesial shift of primary molars into primate spaces, allowing the permanent first lower molar to shift into proper occlusion |
|
|
What is overbite? |
The vertical overlap of the incisors |
|
|
What is affected dentine? |
Demineralised but still remaining structurecollagen matrix, free from bacterial contamination, that is capable of remineralisationunder favourable condition |
|
|
What is infected dentine? |
Amorphous mass of broken down collagen, infected with bacteria that onceformed the structural organic matrix of dentine |
|
|
What is the rationale for using ICDAS? |
Detection and assessment system classifying the stages of the caries process clinically |
|
|
What is the rationale for radiographic assessment? |
System approach in classifying stages of the caries process radiographically |
|
|
What is a tunnel restoration? |
Accessed and prepared by approaching the lesion from occlusal aspect, leaving marginal ridge intact |
|
|
How do you ensure there is a cavitation for a tunnel restoration? |
To improve access and for definite cavitation, an orthodontic elastic can be used. |
|
|
What problems can occur in tunnel restorations? |
- Fracture of marginal ridge - Secondary caries - Limited life expectancy |
|
|
What is the procedure for the time out policy? |
Ask patient to verify their name, date of birth and address and check if pt is accompanied by parent/guardian |
|
|
Who can consent and medical history only be given by? |
It can only be given by parents, legal guardians and foster carers. Delegation of responsibilities for consenting is also seen, but must be in writing. |
|
|
How do you obtain a valid consent? |
Pt/parent must be provided with sufficient material information to have a genuine understanding of treatment, known risks are to be disclosed when there is an adverse outcome |
|
|
What are the three facial profiles? |
Mesognathic - Straight Retrognathic - Convex Prognathic - Concave |
|
|
What are the different lip competencies? |
Competent lips - meet at rest without conscious effort Incompetent lips - do not meet at rest, effort must be exerted |
|
|
What are the effects of digit sucking? |
Increased overjet Greater prevalence of anterior open bite Greater arch depth Narrower maxilla |
|
|
What is a Class I Molar relationship? |
Mesiobuccal cusp of upper first molar occludes on mesiobuccal groove of lower first molar. Upper canine occludes the distal half of lower canine and mesial half of lower premolar |
|
|
What is a Class II Div. 1 Molar relationship? |
Mesiobuccal cusp of upper first molar do notocclude on the mesiobuccal groove but anteriorly to it. Usually the mesiobuccal cusp rest in betweenlower molars and second premolars Div. 1 – molar relationships are like that ofClass II and the anterior teeth are protruded |
|
|
What is a Class II Div. 2 Molar relationship? |
Mesiobuccal cusp of upper molar do not occludeon the mesiobuccal groove but anteriorly to it. Usually the mesiobuccal cusp rest in between lower molars and secondpremolars Div. 2 – molar relationships are Class II butthe centrals are retro lined and the lateral teeth are seen overlapping thecentrals |
