Question | Answer |
Deciduous Dentition Features I | Whiter & More Opaque, Thicker enamel at cervical 1/3. Obvious CEJ (Cervical Bulges) Prominent Buccal Ridges on first molars, Big Pulp Anatomy |
Baby Bottle Mouth | Severe decay in anterior primary dentition caused from sweet liquids (Milk, Juice, Soda) being given in bottle in the crib at bedtime. Sugars sit on teeth all night. |
Deciduous Dentition Features II | Short Crown/Root ration, roots are long, Divergent & thin with no trunk on molars. Narrow occlusal table on molars. 1st molars smaller than second. |
Deciduous Dentition Enamel | Thicker at Cervical 1/3. No mamelons at eruption. Enamel Rods are pointing occlusally. (Permanent rods point to gingiva) |
Lettering of Deciduous Dentition | A-K right to left maxillary. J-T left to right Mandibular. |
Deciduous Dentition - Eruptions Times – Incisors in months | Max Central; 7.5 Max Lateral; 9 Mand Central; 6 Mand Lateral; 7 |
Deciduous Dentition – Eruption Times – Canines | Maxillary; 19 months Mandibular; 16 months |
Deciduous Dentition – Eruptions Times – Molars in months | Max I; 14 Max II; 24 Mand I; 12 Mand II; 20 |
Deciduous Dentition- Maxillary Central Incisor | Facial View – Rounded DI angle, rarely has developmental depressions. Distal Enamel bulge. Crown Shape RECTANGULAR. Lingual View- Big prominent cingulum. Big Marginal Ridges. Deep fossa. |
Deciduous Dentition- Maxillary Central Incisor | Mesial view-FL > permanent Contact is Mid-Incisal 1/3. Distal View is similar with contact at mid1/3. Incisal edge is ~straight. MD >FL Central Cingulum. |
Deciduous Dentition- Maxillary Central Incisor - Root | Root Bends lingual then facial. Round. Longer crown length ratio compared to Permanent. |
Deciduous Dentition- Maxillary Lateral Incisor | Similar to the central incisor - smaller in all dimensions Incisal angles more rounded with the DI much more round than MI IG>MD Roots is relatively longer compared to the crown No lingual pit & lingual anatomy is more prominent than permanent |
Deciduous Dentition- Maxillary Lateral Incisor II | Mesial View- Contact is junction of middle/incisal 1/3. Facial Bulge & Prominent Cingulum. Lateral view is same and same contact. Incisal – MD>FL Root bends lingual then facial. |
Deciduous Maxillary Canine | Convex bulge M&D & Cervical Line. Mesial more prominent. MCR>DCR PENTAGON SHAPE crown. Prominent Lingual Features. (May have tubercle) Mesial contact more gingival due to bulge- mid1/3. Incisal View- Distal cusp tip offset. Longer Mesial cusp ridge. FL>M |
Deciduous Maxillary Canine – Roots | Similar to D.Incisors except they canine’s are longer. |
Deciduous maxillary first molar | Crown resembles permanent maxillary premolar, but has roots of a molar. Greatest dimension of the crown is BL. Only two cusps are prominent |
Deciduous Maxillary first molar | Trifurcation of roots. Small or absent root trunk. Lingual view -MD dimension is narrower than that seen in the buccal view. Cervical line is more even |
Deciduous Maxillary first molar- Mesial | Wider @ Cervical caused by prominent Buccal ridge. Straight Buccal or even concave. Lingual is convex. Narrow Occlusal table. More divergent roots. |
Deciduous Maxillary first molar – Distal View | More Narrow than mesial. DB cusp > DL Cusp. |
Deciduous Maxillary first molar – Occlusal View | H Pattern. Four cusps. |
