1. BEHAVIOUR MODIFICATION
 It involves three techniques:
 DESENSITIZATION
 MODELLING
 CONTINGENCY MANAGEMENT

2. BEHAVIOUR MODIFICATION
DESENSITIZATION
 The concept comes from “systemic
desensitization” used to reduce anxiety in
patients by behavior therapists.
 Patient learns to replace anxiety by relaxation

3. BEHAVIOUR MODIFICATION
DESENSITIZATION
 Joseph Wolpe has suggested that in place of
imaginery scenes, real life contacts can be effective
in a dental situation.
 The method employed is called TELL-SHOW-DO
 Introduced by Addelston
 Involves telling, showing of stimuli in increasing order
of fear, followed by doing the procedures.
 Language chosen should be simple
 The situation is presented to the child slowly and
repeatedly

4. BEHAVIOUR MODIFICATION
DESENSITIZATION
 Indications:
i. Initial visit
ii. Subsequent visits for every new interaction of the child
iii. Apprehensive child due to previous information .
 Effective in children above 3 yrs of age
 Begins from initial entry till completion of the procedure
 The heirarchy of events may be decided by the dentist
for the individual patient

5. BEHAVIOUR MODIFICATION
MODELLING:
 The basic procedure involves allowing the
patient to observe one or more individuals who
demonstrate appropriate behaviors in a
particular situation
 The model may be real or symbolic(posters)
 Was introduced by BANDURA

6. BEHAVIOUR MODIFICATION
MODELLING:
 Steps-
 Gain attention of the patient
 Desired behavior is modeled
 Physical guidance may be needed
 Reinforcement of guided behavior
 Reinforcements for appropriate behaviors without
modelling

7. BEHAVIOUR MODIFICATION
MODELLING:
 It is effective when :
 Observer is aroused
 Model has higher status and prestige
 Associated with positive consequences

8. BEHAVIOUR MODIFICATION
CONTINGENCY MANAGEMENT
 It is a method of modifying the behavior of
children by presentation or withdrawal of
reinforcers
 Reinforcers by definition increase the
frequency of a behavior
 Types of reinforcers:
 Positive: presentation of which increases
behavior
 Negative: withdrawal of which increases
behavior

9. BEHAVIOUR MODIFICATION
CONTINGENCY MANAGEMENT
 Can also be classified as
 Social reinforcers-praise, facial expressions,
physical contact
 Material reinforcers- toys, games. Sweets
should not be given.
 Activity reinforcers- seeing a movie, watching
tv,outdoor games,etc

10. PREAPPOINTMENT PREPARATION
 It involves preparing the child as well as
the parents for the forthcoming dental
visit.
 This can be done by:
 Messages in the form of letters or emails
 by showing videotapes, audiovisual aids
and live models.

11.  Also called as WHITE NOISE
 Involves providing a sound stimulus of
such intensity that the patient finds it
difficult to attend to anything else.
BEHAVIOUR MANAGEMENT
AUDIOANALGESIA

12.  Also called as “suggestion therapy”
 Technique of producing altered state of
consciousness without the use of
pharmacological agents.
 Very rarely used in dentistry.
BEHAVIOUR MANAGEMENT
HYPNOSIS

13.  Children respond to stressful situations by coping.
 It includes an individual’s internal and emotional
processes and his external behavioral responses.
 The way the patient copes with his fears
determines the type of patient he is.
BEHAVIOUR MANAGEMENT
COPING

14.  Mechanisms:
 By thinking of something else- “Distraction”
 Verbalizing fears to others
 Preferring to be with others, say, mother- this is
called “employing affiliative behavior”
 “Mental rehearsal”- going over in one’s mind in
advance the sequence of anticipated events and
reappraising the threats involved.
BEHAVIOUR MANAGEMENT
COPING

15.  It involves a series of basic exercises which the
patient practices at home and may require
several weeks to months to learn.
 Therefore seldom used by clinicians.
BEHAVIOUR MANAGEMENT
RELAXATION

16.  Aversive conditioning
 Aversive conditioning is the extension of overall
behaviour guidance designed to facilitate the
goals of communication, cooperation & delivery
of quality oral health care in difficult children.
 It includes three practices:
1. Voice control
2. Hand-over-mouth exercise (HOME)
3. Physical restraint/Treatment immobilization

17. BEHAVIOUR MANAGEMENT
AVERSIVE CONDITIONING
1. Voice control
 Voice control is a controlled alteration of voice,volume,
tone,or pace to influence & direct the patients behaviour .
 Parents unfamiliar with this technique may benefit from a
prior explanation to prevent misunderstanding
 OBJECTIVES:
I. To gain patient’s attention & compliance.
II. To avert negative or avoidance behaviour.
III. To establish authority
Voice control

18. 2. Hand-over-mouth exercise (HOME)
 popularized by : EVANGELINE JORDAN
 OBJECTIVES:
 To redirect child's attention enabling communication
 To extinguish excessive avoidance behavior
 To reduce the need for sedation or G.A .
 INDICATIONS:
 For uncooperative child
 A healthy child who is able to understand verbal
commands & cooperate , but exhibits negative behaviour
BEHAVIOUR MANAGEMENT
AVERSIVE CONDITIONING Hand over mouth exercise

19.  CONTRAINDICATIONS:
 Child under 3 yrs of age
 Special child (physically, emotionally & mentally
compromised)
 Child with airway obstruction or mouth
breather.
BEHAVIOUR MANAGEMENT
AVERSIVE CONDITIONING Hand over mouth exercise

20.  MODIFICATIONS:
HOM with airway unrestricted
HOM with airway restricted (HOMAR)
Towel held over nose & mouth
Dry towel held over nose & mouth
Wet towel held over nose & mouth

AVERSIVE CONDITIONING Hand over mouth exercise

21. 3. Physical restraint/Treatment immobilization
 It is the direct application of physical force to a
patient with or without the patient’s permission to
restrict his or her freedom of movement.
 It may be:
 Active: Performed with restraining
device
 Passive: Performed without
restraining device
BEHAVIOUR MANAGEMENT
AVERSIVE CONDITIONING Physical restraint

22.  OBJECTIVES:
 To eliminate unwanted movement.
 To protect patient, staff or dentist from injury
 To facilitate quality dental treatment.
 INDICATIONS:
 A patient who requires immediate diagnosis treatment
& can’t cooperate
 When the safety is at risk
 Child who is becoming tired from long appointments
 A sedated pt who requires limited stabilization
 Stubborn child
Physical restraint
BEHAVIOUR MANAGEMENT
AVERSIVE CONDITIONING

23.  PRECAUTIONS:
 Tightness & duration of the stabilization must
be monitored
 The stabilization must not restrict circulation
 Stabilization should be terminated as soon as
possible in a patient who is experiencing severe
stress

24.  TYPES OF RESTRAINTS:
 FOR BODY:
 Pedi wrap
 Papoose board
 Sheets
 Beanbag with straps
 Towel & tapes
 FOR EXTREMITIES:
 Velcro straps
 Posey straps
 Towel & tapes

 FOR MOUTH:
 Mouth blocks
 Banded tongue blades
 Mouth props

26.  Implosion Therapy
 Child patient is flooded with so many stimuli that
he has no other option than to face it, until the
negative behavior disappears.
 It may include HOME, voice control, physical
restraints.
BEHAVIOUR MANAGEMENT
Implosion Therapy

27.  Retraining
 employed in case of children presenting negative
behavior, with bad experience in previous dental visits,
or improper peer or parental orientation.
 The child presents such behavior due to STIMULUS
GENERALISATION, where similarities in stimuli
generate similar responses.
 In retraining, we make the child DISCRIMINATE
between old and new stimuli,
 The older response gradually diminishes - this is known
as RESPONSE EXTINCTION.
