INTRODUCTION
яГШ BEHAVIOR MANAGEMENT-
Behavior management is the means by which dental health team effectivelyand efficiently
performs treatment for a child and at the same time instills a positive dental attitude.(WRIGHT,1975)
DEFINITIONS
яГТ Conscious Sedation :
A minimally depressed level of consciousness that retains the patients ability to independently
and continuously maintain airway and respond appropriately to physical stimulation or verbal command
that is produced by a pharmacological or non pharmacological method or a combination thereof.
яГТ Deep Sedation :
A drug induced depression of consciousness during which patients cannot be easily aroused but
respond purposefully following repeated or painful stimulation. The ability to independently maintain
ventilatory function may be impaired.
яГТ General Anesthesia :
A drug induced loss of consciousness during which the patients are not arousable even by painful
stimulation . The ability to maintain ventilatory function is often impaired.
яГТ Minimal Sedation : (Anxiolysis)
A drug induced state during which patients respond normally to verbal commands

яГТ DRUGS USED
N2O sedation
Horace Wells was an American dentist who pioneered the use of anesthesia in dentistry,
specifically nitrous oxide (laughing gas).
яГТ N2O sedation
INTRA
VENOUS
INTRA
MUSCULAR
ORAL
INHALATION
Inhalational Agents
Benzodiazepines
Other Agents With
Sedative Properties
яГТ Nitrous oxide/oxygen has been shown to be an effective anxiolytic and sedative inhalation
agent for conscious sedation.
яГТ Nitrous oxide is a weak analgesic, most often insufficient to ensure painless dental
treatment.
яГТ Nitrous oxide /oxygen sedation and local anesthesia is an alternative to general anesthesia
яГТ Nitrous oxide/oxygen should be the first choice for paediatric dental patients who are unable
to tolerate treatment with local anesthesia alone and who have a sufficient level of
understanding to accept the procedure.
яГТ It may be offered to children with mild to moderate anxiety to enable them to better accept
treatment which may require a series of visits.
яГТ It can also facilitate the provision of more complex time consuming procedures and dental
extractions particularly for young children or anxious patients undergoing elective
orthodontic extractions.
яГТ Typically delivered through a mask over the nose, nitrous oxide is mixed directly with
oxygen and delivered as the patient breathes in and out regularly.
яГТ The patient is usually asked
to breath normally through the nose,and as the gas begins to take effect, the child will be
come more relaxed and less nervous.
яГТ The gas mixture shall contain a maximum 50% nitrous oxide.
яГТ тАвNitrous oxide/oxygen is reliable in terms of onset and recoveryas long as the patient
accepts the nasal hood and breathes through the nose.
яГТ тАвNitrous oxide has minimal effect on cardiovascular and respiratory function as well as on
the laryngeal reflex.
Indications
яГТ A fearful or anxious patient.
яГТ Certain patients with special health care needs.
яГТ patient whose gag reflex interferes with dental care.
яГТ patient for whom profound local anesthesia cannot be obtained.
яГТ cooperative child undergoing a lengthy dental procedure.
Contraindications
яГТ Pre-co-operative children
яГТ Patients with upper airway problems as common cold, tonsillitis
or nasal blockage
яГТ Patients with sinusitis or recent ENT operations (within 14 days)
яГТ Patients in bleomycin chemotherapy
яГТ Psychotic patients
яГТ Patients with porphyria
PROCEDURE
яГТ Selection of an appropriately sized nasal hood should be made.
яГТ A flow rate of 5-6L/min generally is acceptable to most patients.
яГТ Introduction of 100%oxygen for1-2minutes followed by titration of nitrous oxide
in10%intervals is recommended.
яГТ During nitrous oxide/oxygen analgesia/anxiolysis,the concentration of nitrous oxide should
not routinely exceed50%.
яГТ Nitrous oxide concentration may be decreased during easier procedures(eg,restorations)and
increased during more stimulating ones(eg,extraction,injection of local anesthetic
яГТ During treatment, it is important to continue the visual monitoring of the patientтАЩs respiratory
rate and level of consciousness.
яГТ The effects of nitrous oxide largely are dependent on psychological reassurance. Therefore,
It is important to continue traditional behaviour guidance techniques during treatment.
яГТ Once the nitrous oxide flow is terminated, 100%oxygen should be delivered for five minutes
due to risk of diffusion hypoxia.
яГТ The patient must return to pre treatment responsiveness before discharge
Clinical signs of sedation -
Objective Signs -
1. These signs recorded prior to and 5 minutes after administration .
2. The following signs were examined тАУ
open or closed eyes, tears, smile, speaking, laughing, open or closed hands , limp legs,

яГТ Subjective symptoms-
1. These are addressed the childтАЩs perception of nitrous oxide effects.
2. Questions regarding the childтАЩs perception of nitrous oxide effects on the head
,abdomen,fingers,toes,and overall condition were asked prior to 5 minutes after
administration.
3. The questions were how do you feel,do you feel different ,how does your head feel ,how do
your fingers feel.

GeneralAnaesthesia:
яГТ Definition:
It is defined as a controlled state of unconsciousness accompanied by a loss of protective
reflexes, including the ability to maintain an airway independentlyand respond purposefully to
physical stimulation or verbal command.
яГТ Indications:
1. Patients with certain physical,mental,or,medically compromising condition.
2. Patient who have sustained extensive orofacial trauma.
3. Patient wherein local anaesthesia is not effective or the patient is allergic to it.
4. Fearful,uncooperative,anxious Patient with no expectation that behavior will improve.
Procedure:
Chairsidegeneralanaesthesia тАУ
яГТ Their are 3 common reasons for the use of general anaesthesia are-handicapped or mentally
retarded children , uncooperaative
яГТ child, and inability to come for frequent visits.
яГТ Team includes-1 . Anaesthesiologist
2. pedodontist
3. Dental surgery assistant
4. Anesthesia technicians
Pre-procedure-
яГТ Observations and recording of child behavior.
яГТ The parents are instructed to come for admission one day before the GAprocedure.
яГТ Informing parents about necessity of chairside GA and obtaining verbal consent.
Day1 -
Patient comes to pedodontic clinic.
Concerned doctor send child for preanesthetic check up.
Patient comes back to pedodontics department with report.
If aesthetist accepts the case,patient is admitted.
яГТ Basic investigation are done.
яГТ Written consent form is signed by parents.
яГТ Premedication given to patient
Day 2:-
яГТ Child is brought to pedodontics opds with hospital file.
яГТ Child is accompanied by the parents to the procedure room and is present till induction is done.and
then asked to leave.
яГТ Induction is usually done using inhalation route.
яГТ Once the child is ready under GA the aesthetist hands over the patient to pedodontist.
яГТ Treatment is performed using four handed dentistry.
яГТ Radiographs also taken for treatment plan.
яГТ After completion of treatment dentist handover Patient to anesthetist.
яГТ He administer reversal drugs.
яГТ Child is shifted to ICU .
Day 3:-
яГТ Check up in pedodontics opd.
яГТ Then discharge the patient after payment is done.
яГТ The doctor concerned fixes a follow up appointment.
Commonly used parental anaesthetic agents-:
яГТ Opioids тАУmorphine
. Fentanyl
яГТ Benzodiazepenes тАУDiazepam
. Midazolam
Triazolam
яГТ Barbiturates -: Methohexitol
. Thiopental
Complications of generalanaesthesia:-
яГТ During anaesthesia:-
1.Respiratory depression
2.Salivation,respiratory secretions
3.Cardiac arrhythmia
4.Laryngospasm,convulsions
5.Fall in blood pressure
яГТ After anaesthesia:-
1.Nausea and vomiting
2.Organ toxicities тАУliver,kidney damage
3.Pneumonia
4.Persisting sedation
яГТ Masks for induction:-
яГТ 1.Shape of mask:-
For the children, induction is generally carried out by the use of inhalation.The shape of mask is
modified to make it acceptable to the childтАЩs.
E.g.balloon mask ,Mickey mouse with a wide open mouth.
яГТ 2.Scented mask:
. To disguise the odors of the inhalation agents includes addition of drop of fruit extract on the mask.
Also vapourizing volatile fruit flavours into the anaesthetic gas mixture is acceptable.
Conclusion:-
яГТ Pharmaccologic behaviour management is necessary for children with lack of psychological or
emotional maturity
яГТ Mental , Physical or Medical disability
яГТ One should remember the risks during pharmacologic behaviour management
