Paediatrics Flashcards
what are the OHI for <3 years
1000ppm smear as soon as first tooth arrives
what are the OHI for 3-6 years
> 1000ppm pea-sized
what are the OHI for 7+ years
1350-1500ppm
what can you prescribe for high caries risk children
10+ - 2800ppm toothpaste, 16+ - 5000ppm toothpaste
how often/when can you prescribe fluoride varnish
from the age of 3
low caries risk - twice a year
high caries risk - four times a year
when is pulpotomy indicated
when a vital restorable tooth has:
- large proximal carious lesion
- a carious/mechanical exposure of vital coronal pulp tissue
- no radicular pulpitis
- no abscess/fistula or when extraction is contraindicated
what material is used to get haemostasis in pulpotomies
ferric sulphate
what materials can be used to fill the pulp chamber in pulpotomy
ZOE, MTA, biodentine
what are the steps for pulpotomy
tooth with caries extending into the pulp, pulp chamber accessed and removed with high speed bur, removing necrotic tissue from the root canal entrances with a straight probe, pulp chamber filled with material of choice, preformed metal crown placed
what are the indications for hall crowns
interproximal caries, caries on two or more surfaces, pulp treated teeth
what are the contraindications for hall crowns
pulpal symptoms or caries close to pulp, patients at risk of infective endocarditis, insufficient tooth remaining to retain crown
what are the risks of orthodontic treatment
relapse, decalcification, root resorption, soft tissue trauma, toothwear against appliances, loss of periodontal support, loss of vitality, failed treatment
what is incisal class 1 relationship
lower incisal edges occlude with or lie immediately below the cingulum
what is incisal class 2 div 1 relationship
lower incisal edges lie posterior to the cingulum plateau of the upper incisors, the upper central incisors are proclined or of average inclination and there is an increased overjet
what is incisal class 2 div 2 relationship
lower incisal edges lie posterior to the cingulum plateau of the upper incisors, the upper central incisors are retroclined, overjet is minimal or may be increased
what is incisal class 3 relationship
lower incisor edges lie anterior to the cingulum plateau of the upper central incisors, overjet is usually reduced or reversed
what is the molar class 1 relationship
the mesibuccal cusp of the maxillary first molar aligns with the buccal groove of the mandibular first molar
what is canine class 1 relationship
the mesial incline of the maxillary canine occludes with the distal incline of the mandibular canine, the distal inclination of the maxillary canine occludes with the mesial incline of the mandibular first premolar
what is molar class 2 relationship
the mesiobuccal cusp of the maxillary first molar occludes anterior to the buccal groove of the mandibular first molar
what is canine class 2 relationship
the mesial incline of the maxillary canine occludes anterior to the distal incline of the lower canine
what is class 3 molar relationship
the mesiobuccal cusp of the maxillary first molar occludes distal to the buccal groove of the first mandibular molar
