DEVELOPMENT OF OCCLUSION
GUM PADS
0-6 months of age
Anterior open bite
So such complaint of open mouth by mother at this age
o Rx — self correcting anomaly ! (SCA)
NATAL TOOTH – tooth present at birth
NEONATAL TOOTH — tooth formed within 15 –
30 days.
Most common — mandibular (anterior) central incisor
Syndrome — Rege fede syndrome
Inability to suck milk —
Nutritional deficiency
Lower part of tongue irritation.
ALVEOLAR RIDGE
Transverse grooves — it divides the gum pad into 10
segments for future eruption of the teeth.
CALCIFICATION DATES
1st calcification seen at 14 weeks of IUL, max sinus develops
12th week – mandible
6-10weeks- palate
4-6 weeks- lip
In pedo root formation completes 1year after eruption
As a general rule,
o four teeth erupt for every six months of life,
o mandibular teeth erupt before maxillary teeth,
o teeth erupt sooner in females than males.
o During primary dentition, the tooth buds of permanent teeth develop below the primary
teeth, close to the palate or tongue. Tooth bud is always — lingual / palatal and inferiorly
placed.
