treatment of MIH (functional not aesthetic)
- prevention - high fluoride toothpaste, FV 4x year, tailored OHI, diet advice
- sesnsitivity - tooth mousse may be recommended if suitable
- Fissure sealants - good for molars with no breakdown
- Composite restorations for teeth with enamel breakdown
name 4 advantages of removable appliances

local:
ectopic position of tooth germ
supernumerary tooth in way
crowding
trauma
systemic:
cleidocranial dystosis
down syndrome
nutritional deficiency
hypothyroidism
hereditary gingival fibromatosis
how are infra occluded teeth graded
1 - occlusal surface above contact points of adjacent tooth
2 - occlusal surface at contact point
3 - occlusal surface below

what is behaviour management
focuses on communication and education
aims to build trusting relationship between dentist and patient

proclination of lower incisors
mesial movement of lower teeth
distal movement of upper teeth
an IOTN aesthetic score of what indicates a need for treatment
score 8-10 = definite tx need
5-7 = borderline
name 4 potential causes of a midline diastema
hypodontia
tooth size: arch size discrepancy
midline supernumerary
low labial frenum
proclination of upper labial segment
name 3 dental anomalies that commonly occur in cleft patients
hypodontia
supernumeraries
delayed eruption
hypoplasia
what malocclusion is commonly seen in CLP
class III

- under 3 smear of 1000ppm
- 3-7 1350ppm
- 7+ 1500ppm
- high risk 10-16 = 2800ppm
- high risk 16+ = 5000ppm
name 3 proposed methods of mass fluoride delivery (in particular to children) and mention a pro and con
water - very cheap , ethical concerns
salt - cheap, encouraging salt intake?
milk - cheap , not everyone likes milk
intramembranous vs endochondral ossification
intramembranous - bone developsdirect from primitive mesenchymal tissue

flat bones
maxilla
frontal
mandible
2 examples of endochondral ossification
ethmoid
sphenoid
