Vital pulpotomy aim
to remove the infected cornal part of the radicular pulp, stop bleeding and main the apical portion of pulp
Steps in vital pulpotomy
LA, rubber dam and gain acces to carious lesion
remove carious lesion and gain acees to the roof of bulb chamber with diamond bur
remove the cornoal pulp with steel bur or excavator
establisht ehextent of bleeding apply a ferric sulphate soaked pellet over the pulp and gain haemharrage control, if bleeding continues then reapply and wait till control achieved
resotre with ZOE paste and GIC core adn then restroation
Ferric sulphate
only used in primary teeth as casues staining and darkenin in adults
use nsCAOH or CaOH in adults
follow up for vital pulpotomy
6months clincally
12months radiographically looking for furcaiton involvement, pa path, internal and external resoorption
Pulp capping
mainins the vitatility of the tooth <24hrs exposure
arrest heammrahge with pressure and damp cotton wool rool
apply CaOH over the site and then resotre
Non vital pulpectomy
the only option to save a non vital tooth
pulp necrosis, chronic sinus, pa perio, bleeding pulp or inflammed pulp
Apexification
induces a calcified barrier in the root of incomplete or open apices with a necrotic pulp
Non vital tooth on xray
Pa radioluency
external or internal root resoprtion
widening of PDL
loss of lamina dura
anklyosis
Contraindications to inhaltion sedation
can’t breathe through nose
common cold
severe asthma
tonsillar enlargement
severe copd
Reasons good for inhaltion sedation
rapid onset
quick recovery
no needles/cannulation
no amnesia
drug is not metabolised in liver
adults do not need cahperone
matinance of protective reflexes
Contraindications of GA
allergy to the Ga drug
liver function issues
renal issues
ECG abnormalities - long QT syndrome
Cystic fibrosis
Severe astham - class ASA 3 and 4
resp disease
cogential heart defects
sickle cell anemia
Fasting for GA
6 hrs - no solids
4 hrs - no milk
2hrs - no clear fluids
GA recommendations
stop smoking 12 hrs before GA
Alcohol - if regular the liver enzymes can be reduced which has an affected on absorbing the anesthetitc
need escort home and someone to monitor them for 12 hrs
Extrinsic staining
tea/coffee/drinks
poor OH
smoking
drugs - iron = black, CHX = brown/ blakc
Intrinsic local staining
infection/path present
internal resoprtion
caries
injury/infection
Systemic staining
flurosis
amelgeogensis imprefect
dentitignsisi imprefecta
drus - tetracycline
bilirubim
10% carbamide peroxide brown down to
3% hydrogen peroixde
7% urea
When are composite veneers not apporpriate
in children the pulp horns and chambers and stillll quite large
the gingival contour is still immature
Causes of toothwear in children
parafunctional habits
gastric probs
dietary issues
Objective of resotring tooth wear
improve senstiivity
to have a balanced occlusion
to resotre function
to presevre remaining tooth tissue
support remaining tooth struture
When is microabrasion indicated
flurosis
trauma to teeth
MIH
post ortho demineralisation
white/brown surface staiing
Advantages of microabrasion
quick and easy
non invasive
conservative of tooth structure
no LA required
effective
not expensive
Disadvatanges of microabrasion
HCl caustic
has to be carried out at GDP
unpredicatble outcome
removes enmale so can lead to sens
Steps in microabrsion
apply rubber dam and pumice and water to tooth to clean
then apply petreleum jelly to soft tissues
then apply sodium bicarbonate to gingivae
apply Hcl slurry for 5secs on each tooth and rinse
repeat 10 times and review
wash and polish with flexi discs and apply flurodie varnish to help with reminerlisaiton and sens
review in 4-6weeks
** advise not to consume dark fluids and food for 24hrs
Other types of tx for disclouration
resin infiltration
bleaching - vital bleaching e.g chairside bleaching, non vital bleaching
Types of non vital bleaching
walking tech - which creates cavity into pulp chamber and bleach applied directly in and sealed over and reapplied at intervals
inside out tech - where cavity cut into pulp and pt then applies bleaching gel in tray and into mouth and over the area with pulp cavity
Hypomineralisation
where there is reduced enamel formed or the ennamle mineral content is reduced
Hypoplastic
enamel bulkl, thickness is reduced
enamel morophology is not right
Questions to ask for MIH
pre natal - mum in 3rd trimester, pre-elampsia, gestational diabetes
peri natal - traumatic birth, baby full term or premature
post natal - prolonged breast feeding >6months, fever, meds, resp issues, chickenpox, mumps
Clincal issues with MIH
sens
tooth wear
appearance
breakdown of enamel
secondary caries
Traumatic injuries what toask
how the injury occured?
when the injury occured
where the injury occured - to establish if tetnus is required
crown framgments lost etc
amensia, concussion, vomiting, headaches
have they had previous dental trauma
Mh - allergies - for antibiotics
Tetanus in last 5 years
bleeeding disorders
congientia lheart defect, immunosuppresion or rhemuatic fever as don’t want to carry out endo
Avulsions more successful when
minimal damadge to the pulp and perio ligament
the correct sotrage medium and the extra avlolar time small
When not to reimplant a tooth
if child is immunocomporomised
if the child has other medically issues that take priorioty
pt lacks co-operation
Public advice for avulsion
hold the tooth by the crown
remove debris with cold running water and a plug in the sink
try and reimplant into the socket
if can’t store in milk or saliva
seek dental advice
Avulsion
complete removal of the tooth from the socket
sepration of PDL and exposure of root surface
Concussion
there is no rupture of the perio ligament
limited ging bleeding, some swelling
no increase in mobility
TTP yes
tx - soft diet, good oh, chex and gentle brushing
