|
dental caries
|
Demineralized-loss of calcifed tooth
begins usually in pits/fissure and interproximal area |
|
|
Loss of teeth consequences
|
Loss of proximal contacts-->medial drift
Unstable ICP: supereruption of opposing unstable teeth in arch |
|
|
Anterior tooth most likely to have burfaction
|
Mandibular K9(facial lingual roots)
|
|
|
Mandibular 1st furcations
|
Centered, buccal and lingual entrances
Buccal: 3mm from cej Lingual: 4 mm from cej |
|
|
Maxillary Molar furcations
|
Mesial: 3mm, lingually offset(2/3 to lingual from buccal)
Distal: 5mm, central Buccal: 4mm, central |
|
|
Periodontal Problem areas
|
Max Lateral incsior lingual surface
Root surface and mandibular anteriors Distal maxillary k9, medial 1st premolar |
|
|
Lingual Max Lateral
|
-Lingual pit/groove
-Lingualgingival groove -distolingual marginal groove(dwon to root) |
|
|
Longitudnal Root Grooves
|
-Prominent on distal root surfaces of mandibular anterior teeth
|
|
|
Max K9 + 1st premolars
|
-Both have crown concavities(maxillary k9 distal, 1st premolar, mesial) near gingiva to contact
-difficult areas to clean, especially at proximal contacts |
|
|
Most periodontally fragile tooth
|
1st max. premolar
concavities, mesiomarginal developmental groove, longitundal root groove, furcation, 2 roots |
|
|
Healthy Periodontium
|
1. Proximal Contacts: correct size and location
-easier to get food stuck -large=lose embrasure, no floss -little = food stuck 2. Embrasure Form: symmetry and size 3.Marginal Ridge Height -need to be same 4. Crown contours cervical 3rd height of contour 5. Occlusal stability -well distr. icp contacts and forces on long axis of teeth |
|
|
Roots/canals: Anteriors
|
1 Root/ 1 canal
|
|
|
Maxillary Premolar pulp anatomy
|
1st: 2 roots 2 canals
dumbell shape as furcation is more apical |
|
|
2nd Max Premolar, Mandibular premolars
|
1 root 1 canal
|
|
|
Maxillary First Molar
|
3 roots, 4 canals
2 canals in mesial bucal root(60%) apical split |
|
|
Second Maxilary first
|
3 roots, 3 canals
with some variabilities |
|
|
Mandibular 1st molar
|
2 roots, 3 canals
2 canals in mesial root 30% have distal as well |
|
|
Mandibular 2nd molar
|
2 roots, 2 canals
|
