Review of D2 Material Flashcards
What is a rubber dam preparation technique: hole is punched for most anterior tooth and a hole punched for most posterior tooth to be isolated, then holes are connected with a slit?
Slit Dam Technique
What is the most common mistake in restoration of primary teeth?
Over-extension of preparartion
What restoration is indicated if excessive tooth structure must be removed in primary teeth?
Extracoronal restoration = stainless steel crown (SSC)
What is the depth of the preparation for a primary posterior tooth restoration?
1.0 mm
What is the width of the preparation on a mandibular first primary molar?
1/3 intercuspal distance
What is a restoration used to restore caries in a primary molar with limited involvement of the proximal surface?
Class II
Is a class II restoration indicated when proximal caries have broken through the marginal ridge clinically?
No. SSC is indicated.
What is the hardest contact to break on a primary molar class II prep and why?
Gingival contact because primary teeth have broad, flat contact.
The following indicate what restoration on primary teeth:
- Large lesions on primary teeth
- Rampant caries
- Pulp therapy
- Developmental defects
Stainless steel crown
Can a stainless steel crown be used on a permanent tooth and when (with respect to pediatric dentistry)?
Yes. Temporary restoration of young permanent tooth
Which should be done first in a SSC prep: caries removal or interproximal slices and why?
Caries removal first. Blood from interproximal slices could mask blood generated by pulp exposure during caries removal if done in reverse order?
Placing a base and liner over caries that would otherwise result in a pulp exposure, when there is no indication of a pulp exposure, there is no unstimulated or long term pain, and no signs or symptoms of pulap degeneration?
Indirect pulp cap
On what tooth type is a direct pulp cap never done?
Direct pulp cap? WTF?
What is the term for the amputation of the coronal portion of the pulp, with the reamining tissue in the roots (radicular pulp) remaining vital?
Pulpotomy
What is the appearance of the blood and time for hemostasis after a pulp exposure, either carious or mechanical in a primary toth that indicates a pulpotomy?
Red and normal blood (not necrotic)
Bleeding controlled in 3-5 minutes
How much root length must remain on a primary tooth for a pulpotomy to be indicated?
2/3 root length left
What are pulpal medicaments that can be used for a pulpotomy?
- Formocresol
- Ferric sulfate
- MTA
- Pulpectomy
Is a pulpectomy indicated in a primary tooth if there is furcation involvement or the surrounding root and bone have pathology?
No
How much primary tooth root should remain for a pulpectomy to be indicated?
1/2 of root length remains
Why is it important to keep 2nd primary molars (A,J,K,T)?
Guide eruption of 1st permanent molars
What is indicated for a primary tooth, necrotic pulp, with no permanent successor?
Pulpectomy
The following are all risk factors for what disease?
- Frequent feeding / snacking on fermentable carbohydrates
- Poor oral hygiene
- Lack of fluoride
- Enamel defects (could be due to low birth weight or premature birth
- Chronic medical conditions
- Low socioeconomic status
Early Childhood Caries (ECC)
How much fluoride toothpaste is indicated for a child less than 2 years old?
Smear and supervised brushing
What amount of fluoride tootpaste is indicated for a child between 2-5 years old?
Pea size and supervised brushing
What is the dosing of 2% lidocaine with 1:100 Epi?
4.4 mg/kg
1 kg = hoy many lbs?
1kg = 2.2 lbs
How many mg of LIdocaine are in 1 carpule (1.8mL)?
20x1.8 = 36mg Lido / carpule
What is the maximum 2% Lidocaine 1:100 Epi dose for 67lb child?
((1kg / 2.2lbs ) x 67lbs) x (4.4mg / kg) x (1carp / 36mg) = 3.7 carpules 2% lidocaine for 67lb child
What is the dosing of 4% Septocaine 1:100 Epi?
7 mg / kg
How many mg of Septocaine are in 1 carpule (1.8mL)?
40 x 1.8 = 72mg / carpule
What radiograph schedule is indicated for a recall patient with clinical caries or increased risk factors for caries in the primary, transitional, and adolescent permanent dentition?
Posterior bitewings every 6-12 months
What radiograph schedule indicated for recall patient with no clinical caries and no increased risk factors for caries in the primary and transitional dentition?
Posterior bitewings every 12-14 months
What radiograph schedule is indicated for recall patient with no clinical caries and no increased risk factors for caries in the adolescent permanent dentition?
Posterior bitewings every 18-36 months
What is eruption age for a permanent maxillary central incisor?
7-8
What is eruption age for a permanent maxillary lateral eruption?
8-9

10-11
What is eruption age for a permanent maxillary second premolar?
10-12
What is eruption age for a permanent maxillary first molar?
6-7 (6 year molars)
What is eruption age for a permanent maxillary second molar eruption age?
12-13 (12 yr molars)
What is eruption age for a permanent maxillary third molar?
17-21
What is eruption age for a permanent mandibular central incisor?
6-7

6-7 (6 yr molars)
What is eruption age for a permanent mandibular second molar?
11-13 (12 yr molars)
What is eruption age for a permanent mandibular third molar?
17-21
What are Dr P’s generalizations about tooth eruption, root formation, and missing teeth?
- Mandible ahead of maxilla
- Girls before boy
- Permanent roots close 3 years post eruption
- The second of a tooth type is more likely to be congenitally missing than the first (e.g. the 2nd PM is more likely to be missing than the 1st PM)
What are 3 basic behavior management techniques?
- Tell-Show-Do
- Nitrous Oxide
- Voice control
