COMPONENTS OF THE DENTAL EXAM
• MEDICAL HISTORY
• BEHAVIORAL ASSESSMENT AND GENERAL APPRAISAL
• EXTRA-ORAL EXAM: HEAD, NECK, FACE, HANDS
• INTRA-ORAL EXAM
• CARIES RISK ASSESSMENT (CRA)
• RADIOGRAPHIC EXAMINATION
GENERAL APPRAISAL
• THE CLASSIC AREAS OF THIS APPRAISAL INCLUDE GAIT,
STATURE, AND PRESENCE OF GROSS SIGNS AND
SYMPTOMS OF DISEASE. THE NORMAL 3- TO 6-YEAR-
OLD IS AMBULATORY, WELL COORDINATED IN BASIC
TASKS, ENGAGING, AND PHYSICALLY HEALTHY IN
APPEARANCE. TABLE 18-2 LISTS PHYSICAL AND
BEHAVIORAL MILESTONES FOR THE 3- TO 6-YEAR-OLD
CHILD. THE GENERAL APPRAISAL OF THE CHILD IS BEST
ACCOMPLISHED IN THE WAITING ROOM OR SIMILAR
NONTHREATENING ENVIRONMENT. THIS APPRAISAL
SHOULD BE FOLLOWED BY CLARIFICATION OF ANY
ABNORMAL FINDINGS AND DISCUSSION OF POTENTIAL
BEHAVIOR PROBLEMS WITH THE PARENT. HEIGHT AND
WEIGHT RECORDED TO MONITOR DEVELOPMENT.
MEDICAL HISTORY CONSIDERATIONS
General Health Common Findings
Allergies Probably related to food and other environmental allergens; may have allergy to medications such as antibiotics
Asthma May be reported; triggering factors usually known; medications also well known; impact of dental intervention
usually not known
Bleeding Parent may suggest excessive bruising without real problem
Blood Transfusion May have been performed at birth
Childhood Infections Immunizations will have occurred, or there is a clear history of having had a specific illness such as measles or
chickenpox
Development Poor parental knowledge for normal child development
Heart Functional murmur may exist, or parent may have been told of a murmur
Hypertension Usually unknown, unless child has a chronic problem
Illnesses Probable history of upper respiratory infections
Jaundice Possible at birth
Medications Probably has taken acetaminophen as necessary; may have received amoxicillin or other antibiotic
Surgical Procedures Possible tonsillectomy or adenoidectomy; possible ear tubes
Seizures Possibly febrile; may be on seizure medication for only one seizure
DENTAL HISTORY CONSIDERATIONS
Dental Health Common Findings
Bottle Use Probably considered not to contribute to decay
Developmental/Eruption Knowledge may be limited to eruption dates of first teeth, unless consistently
very early or late
Fluoride May know water status; possible vitamin with fluoride supplementation
Habits (thumb sucking) Will be well known to parent if present
Home Care Usually confined to tooth brushing; may be largely left to child
Previous Care Possible none
Reaction to Care (behavior) Likely poor or tentative
Trauma to Teeth and Chin Possible, usually left untreated unless serious; commonly upper teeth and chin
COMMON GENETIC CONDITIONS
Noonan
syndrome
Down syndrome
William’s
syndrome
Fragile X
syndrome
Treacher-Collins
syndrome
Osteogenesis
imperfecta
GENETIC DISORDERS AFFECTING TOOTH DEVELOPMENT
• VAN DER WOUDE- LOWER LIP PITS; CLEFT LIP/PALATE; CLEFT UVULA; HYPODONTIA
• AMELOGENESIS IMPERFECTA- ENAMEL DEFECTS THAT AFFECT BOTH DENTITIONS; APPEARANCE IS
YELLOW-BROWN TO ORANGE DEPENDING ON SUBTYPE; TEETH ARE SENSITIVE, SUSCEPTIBLE TO WEAR,
AND MAY ALSO HAVE TAURODONTISM IN MOLARS
• DENTINOGENESIS IMPERFECTA- BOTH PRIMARY AND PERMANENT TEETH ARE AFFECTED; TEETH ARE
BLUE-GRAY OR BROWN; SUSCEPTIBLE TO EXTREME WEAR; PULPAL OBLITERATION AND DENTAL
ABSCESSES
• HYPOPHOSPHATASIA- PREMATURE LOSS OF TEETH DUE TO LACK OF CEMENTUM; CRANIOSYNOSTOSIS
• ECTODERMAL DYSPLASIA- FULL LIPS; SMALL NOSE; HYPODONTIA; CONICAL OR MALFORMED TEETH;
DEFICIENT ALVEOLAR RIDGE
• CLEIDOCRANIAL DYSPLASIA- FRONTAL BOSSING; BRACHYCEPHALY; LATE CLOSURE OF FONTANELLES;
HYPERTELORISM(INCREASED DISTANCE BETWEEN THE EYES); DELAYED ERUPTION OF PERMANENT TEETH;
SUPERNUMERARY TEETH; IMPACTED TEETH
EXTRA-ORAL
EXAM
• be aware of thickness or amount for ectodermal dysplasiaHair
• look for abuse, dermatitisScalp
• malformed ears as in Treacher collins syndrome, hearing
loss
Ears
• Position of eyes including upward or downward slanting of
fissures, stellate pattern in iris is for William’s syndrome
Eyes
• misshapen=ectodermal dysplasia, asthma, allergies, cleftsNose
•Many children of this age have swollen nodes, but the nodes are usually
movable and confined to the lower face and jaws and are indicative of
minor infection. Swollen nodes in the neck and clavicular region are
more rare and may indicate more serious ailments.
Lymph nodes:
• increased size=goiter, tumorThyroid:
• through visualization, should have absence of lesions, poor
closure lip incompetence, clefting, asymmetry/bell’s palsy
or cranial nerve damage, ulceration or herpes infection
Lip:
• edema or cellulitis=renal disorder, redness=allergies?
Dryness or dehydration=ectodermal dysplasia,
ulcerations=abuse?
Skin:
• scars=trauma?Chin:
PEDO EXAM:
EXTRAORAL
PALPATION
EXTRA-ORAL EXAM: FACIAL PROFILE
A: Class I skeletal relationship is characterized by a well-balanced profile in the
anteroposterior dimension. These relationships can be judged by mentally connecting the
points of the bridge of the nose, the base of the upper lip (maxilla), and the soft tissue chin
(mandible). This line should be slightly convex.
B: Class II skeletal relationship is characterized by a truly convex profile.
C: Class III skeletal relationship is characterized by a straight or concave profile.
