Sample Questions

 

 

Pulp Therapy for Primary and Young Permanent Teeth

1)      Indicate the relative value and degree of reliability of the various diagnostic parameters in primary and young permanent teeth

Parameter

Component

Value

Radiographic Examination

Pathologic Bone Resorption

- May indicate widespread pulpal necrosis and non-vitality of associated tooth

- Care should be taken with primary dentition as radiolucencies in bone may be normal and associated with development of tooth

Pathologic Root Resorption

- Indicates presence of prolonged infection

- No pulp therapy here

Internal Resorption

- Indicates advanced degeneration in pulp

- Pulp therapy unsuccessful (unable to stop the resorptive process)

Calcific Mass/Globules

- Indicate advanced degeneration of pulp

- Also spread of inflammation

Soft Tissue Examination

- Soft boggy tissue

- Swollen, inflamed

- Exudate accumulation under skin (parulis)

- Chronic may show as a fistula

- Severe may show as cellulitis

Pulpal necrosis will often manifest with changes in the soft tissue

 

Any of these situations indicate irreversible state and most likely necrotic

Pain

Absence of pain

- Cannot be used as the sole criterion for pulpal necrosis

- Many primary pulps degenerate and become necrotic without pain

Presence of pain

- Can aid in determining pulpal health

- Spontaneous/unsolicited toothache is evidence of advanced pulpal degeneration

- May also indicate food impaction or excess cement from a recent SSC

- Solicited pain (i.e, chewing) indicates lesser degree of inflammation

- History of pain indicates extensive pulpal inflammation

- Sharp pain may indicate carious exposure of dentinal tubules (brought on by hot/cold/sweet)

- Throbbing pain indicates pulpal inflammation, but is not definitive

Mobility

Relates to the degree of resorption of the root whether normal or not

- Teeth with necrotic or extensively inflamed pulp often exhibit mobility

- Not diagnostically valuable alone

- May be valuable with radiographic evidence

Percussion

Better with older children

- May indicate PDL inflammation

- Depends on the reliability of the child’s response

- Little diagnostic value in young children

Pulp Tests

Primary Teeth

EPT, and  Hot/Cold Tests

Often unreliable

Little or no diagnostic value

False positives are common

Permanent Teeth

Vitalometer à particularly valuable for fully formed tooth, but NOT partially developed

Hot/Cold Tests à also valuable

 

2)    Suggest the status of the pulp based on a review of the diagnostic parameters

Use the information in question 1

3)    Given all necessary diagnostic information in a case study format, recommend appropriate treatment for the pulp

Procedure

Benefits

Indications

Contraindications

Formocresol Pulpotomy

Indirect Pulp Cap

Glass ionomer«is used to cover the area left after all caries removed except that which is directly over the pulp chamber

- Relatively simple to perform

- Carious dentin that has not completely demineralized can remineralize

- Seal off bacteria in deep layers of dentin which become dormant

- Does not produce surgical trauma by mechanically invading the pulp chamber

- Dose not introduce dentin chips and bacteria into the pulp

- Produces more reparative dentin than direct pulp caps or pulpotomies

- Radiograph shows that a near or probable pulp exposure exists

- No history of prolonged or spontaneous pain

- No sensitivity to percussion

- No redness or swelling

- No mobility

- No bone loss

- No internal resorption

- A definitive, positive response to vitalometer

- Primary teeth with deep caries

Direct Pulp Cap

A minimally exposed pulp is protected with an antiseptic and sedative agent

- Allows pulp to recover and maintain its normal vitality and function

- Vital pulp

- No history of prolonged or spontaneous pain

- No sensitivity to percussion

- No redness or swelling

- No mobility

- No bone loss

- No internal resorption

- Traumatic exposure when treated within a few hours

- Pin-point exposures

- Pt in good general health

- Use in Permanent Teeth only

- Primary teeth with carious pulp exposure (high failure rate near 50%)

Apexogenesis

(CaOH Pulpotomy)

- Pulp may not remain healthy, but it will be strong enough to undergo RCT

- MTA is preferred over CaOH due to better biocompatibility

- Allows apex to mature and dentin walls the thicken

- Allows radicular pulp to remain vital

 

- Young vital permanent teeth with incomplete apices

- Large pulpal exposure during caries removal in asymptomatic teeth

- Traumatic injury with pulpal exposure

- No history of prolonged or spontaneous pain

- No sensitivity to percussion

- No redness or swelling

- No mobility, bone loss, or internal resorption

- Not for primary teeth

Apexification

- Provides apical stop to facilitate obturation of canal

- MTA is preferred over CaOH

- Incompletely formed roots of non-vital permanent teeth where a pulpectomy is indicated

- Not for primary teeth

4)    After appropriate diagnosis with an understanding of benefits, indications and contraindications, be able to perform the following

Procedure («)

Technique

Formocresol Pulpotomy

1.     Access pulp chamber w/ #330 bur

2.     Remove pulp tissue w/ sharp excavator or slow speed round bur (#4,6,8)

3.     Flush chamber with water then dry with cotton pellet
bleeding is controlled with moist pellet application for 1-2 minutes
Red Eye” Stage is when bleeding has been controlled
Before proceeding check for: no overhangs, no tissue tags, have all canals, no perforation

4.     Formocresol moistened cotton pellets are placed to cover the floor of the chamber
allow to remain for 5 minutes
formocresol on gingiva will cause tissue necrosis
Buckley’s Formula
à 35% tricresol, 19% formaldehyde, 15% water
Black Eye” Stage
à pulpal tissued fixed, and no bleeding

5.     Fill pulp chamber with a thick mix of IRM
important to achieve a good seal
tap down with wet cotton swab tip

6.     Reduce occlusion and use IRM as temporary
SSC is posterior restoration of choice (prevents fracture)

Pulpectomy

Complete removal of pulp tissue from a non-vital primary tooth

1.     Access pulp chamber w/ #330 bur

2.     Remove all necrotic tissue from chamber and canals
careful to avoid pushing infected material through apex
rinse with NaOCl and then dry

3.     Instrument canals with endo files (30 or 40 for molars, larger for anteriors)
stop 2mm short of radiographic apex
goal is only to remove bulk of bacteria and provide an opening for material

4.     Dry canals with paper points, then fill with ZOE
DO NOT use IRM
à will resorb rest of tooth

5.     Canals can be filled using root canal condensers, a Lentulo spiral, a pressure syringe (Pulpdent), or a Eugoseal syringe (Centrix)

6.     Restoration of choice is SSC for posteriors

Indirect Pulp Cap

Glass ionomer«is used to cover the area left after all caries removed except that which is directly over the pulp chamber

1.     Prepare tooth to ideal
remove all unsupported enamel
remove decay with spoon or round bur
DO NOT remove decay that is immediately overlying the pulp

2.     Place a layer of glass ionomer covering all exposed dentin
seals dentin over area of near-exposure
prevents ingress of bacteria
allows pulp to heal

3.     IF dentin is sound, then a restoration can be placed
advise parents that additional treatment may be needed

4.     IF affected dentin remains, place an IRM temp for 6 months
re-treat in 6 months to 1 year with new glass ionomer and final restoration

Direct Pulp Cap

A minimally exposed pulp is protected with an antiseptic and sedative agent

1.     Prepare tooth to ideal
remove all unsupported enamel
remove ALL decay with spoon or round bur

2.     IF pulp is exposed, and criteria are met for Direct Pulp Cap…
then control bleeding with cotton pellets and dry
exposure areas >1mm diameter should be reevaluated

3.     Apply MTA over the exposure

4.     Cover MTA and remaining deep dentin with glass ionomer (ensure complete seal)

5.     Place restoration similar to steps 3 and 4 of indirect pulp cap

Apexogenesis

(CaOH Pulpotomy)

1.     Proceed with steps 1, 2, and 3 of Formocresol Pulpotomy

2.     Place MTA over amputated stumps

3.     MTA and surrounding tooth structure is covered with glass ionomer

4.     Final restoration may be placed, but additional treatment may be needed later

5.     Secure two radiographs prior to patient dismissal used for future comparison
- a post-op PA of involved tooth
- a post-op bitewing

6.     Recall the patient in 6 months to check status
take PA and bitewing to evaluate maturity of roots
IF mature and asymptomatic, place final restoration
IF NOT, recheck in 6 months

7.     Subsequent recalls will depend on patient’s progress

Apexification

1.     Pulpectomy

2.     Irrigate with NaOCl

3.     Dry canals with paper points

4.     Place apical MTA plug to create apical stop

5.     Fill with gutta-percha and monitor for periapical healing

6.     Get a post-op PA and bitewing

7.     Recall patient in 6 months
evaluate with new PA and bitewing

5)    Discuss the reaction of pulpal tissue to formocresol

Formocresol contains formaldehyde and cresol.

Formaldehyde à results in varying degrees of loss of pulp vitality

     Forms intra- and inter-molecular bridges between various amino groups

     Results in a fixing of the tissue (prevents autolysis)

Cresol à expected to cause pulpal necrosis

     Disrupts the cell-membrane and denatures proteins

Will provide some bactericidal benefit (“sterilizes”) pulp interface, but also causes some damage

Acts to chemically cauterize area surrounding radicular stumps in pulpotomy

Induces a limited zone of inflammation in the pulp tissue

 

6)    Understand why it is not advisable to use direct and indirect pulp caps in the primary dentition

Direct pulp caps are not used in the primary dentition

à because of high failure rate (near 50%)

Indirect pulp caps are not typically used in primary dentition

à because there is usually a small pulpal exposure

à if used, all dentinal tubules must be covered with glass ionomer («)

 

7)    Discuss the treatment planning considerations in deciding to perform a complete pulpectomy on a primary tooth

General Health of the Patient

     Immunocompromised or at risk for SBE is not a candidate

Tooth involved

     Primary anterior teeth can readily be treated (large canals, easy access)

     These become devitalized more often from trauma

Chronology

     Critical to preserve primary molar during period of primary dentition (as opposed to mixed)

     As primary molars age, there is á deposition of secondary dentin creating irregularities in the canal

 

8)    Know the appropriate treatment for emergency pulpal problems

Usually associated with advanced degeneration of pulp

Usually requires pulpectomy, for preservation of tooth

Extraction is an alternative

Antibiotic Therapy for pyogenic infections (fever alone is not an indication for antibiotics)

     Amoxicillin 20-40 mg/kg/24hr Q 8h

          Clindamycin 10-25 mg/kg/24hr Q 8h (for penicillin sensitivity)

          Acetaminophen (or other analgesic may be necessary)

     Treatment should never be attempted with systemic antibiotic alone

     Extractions are not done in the presence of acute infection              

 

9)    State the indications for the use of mineral trioxide aggregate, glass ionomer materials, ZOE and IRM

Mineral Trioxide Aggregate (MTA)

- Powder of hydrophilic particles

- Sets in the presence of moisture

- Highly biocompatible

- Forms a good seal, once set

- May have some inductive effect on cementoblasts

- Placed over pulp exposure in direct pulp caps

- Also over amputation stumps in apexogenesis

- Also an apical plug/stop in Apexification techniques

Glass Ionomer Materials

- Ideal for sealing dentin due to adhesive characteristics

- Releases fluoride

- Fast setting (light cured)

- Micro-mechanical attachment with composite

- Somewhat soluble in oral fluids

- May wash out over time

- Hybrids are much less soluble; retain excellent dentin seal

- Placed over deep portions of moderate/deep carious lesions

- Also placed over MTA to prevent microleakage

Zinc Oxide & Eugenol (ZOE)

- An obtundant (sedative) and effective insulator

- Forms a good seal to prevent leakage, salivary contamination and pulpal degeneration

- Inhibitory of microbial growth (not destructive)

- Is hygroscopic (removes moisture)

- Non-irritating to the pulp (similar pH)

- Eugenol, alone, can be toxic to tissues

- Used to fill root canals of pulpectomized primary teeth

- Does not set to hard consistency, so it is highly resorbable

- Not a good restorative material

Reinforced Zinc Oxide & Eugenol (IRM)

- May prevent in-growth of bacteria (due to good seal and/or bactericidal properties)

- Used as a temporary restoration for caries control in primary teeth

- May be used for direct or indirect pulp caps in permanent teeth

- Also used in the pulpotomy procedure in primary teeth

 

10) Be familiar with Pacific Pediatric Clinic policies and procedures («) relating to pulp therapy and young permanent teeth

Formocresol Pulpotomy, Pulpectomy, Indirect Pulp Cap, Direct Pulp Cap, Apexogenesis, Apexification

Management of Traumatic Injuries in Pediatric Patients

1)      Describe and understand the general characteristics of trauma incidents as they relate to patient dentition

Primary Dentition

Mixed Dentition

- 1.5 – 2 years of age

- first steps, á motor coordination

- luxation injuries are more common (short clinical crowns, less calcified bone, thin cortical plates)

- 8 – 11 years of age

- sports related, â parental supervision

- class II with significant overjet predisposes incisors to traumatic injury

- dental fractures are more common (longer clinical crowns, bone more dense, thicker cortical plates)

Luxation is just a fancy word for dislocation

 

2)    Know the components of thorough trauma assessment and the importance of each

History

* Soft tissue management (any fragments?)

Extra-oral Exam

* Other injuries requiring treatment

* Consciousness assessment à chance of concussion?
loss of consciousness, amnesia, vomiting/nausea, unequal pupils

* Oral Function à a blow to the chin can cause condyle fract.

Intra-oral Exam

* Assess secondary injuries

* Look for debris/fragments in tissue

may need to confirm with x-ray

Radiographic Exam

* Root development of involved teeth

* Locate/delineate fracture (x-rays from diff. angles)

 

3)    Know the general principles for treatment of trauma injuries

Initial Treatment

* Calm patient and/or parent

* Clean child’s face for clear visualization of injuries

* Explain each step to child before you do it

    • Severly traumatized teeth
    • Supernumerary and ankylosed teeth
    • Over-retained primary teeth that cause ectopic eruption
    • Removal of teeth for orthodontic purposes

 

3)    Discuss appropriate local anesthesia techniques in pediatric patients

Profound local anesthesia is essential, and should be confirmed prior to starting extraction

Nitrous oxide/Oxygen analgesia is often useful

See Fall Midterm Review for anesthesia techniques

 

4)    Know armamentarium for extraction of maxillary and mandibular primary tooth extractions

    • Periosteal elevator
    • Curette (can be used for epithelial separation for anterior tooth extraction)
    • Straight elevator
    • Forceps for primary molars à 150S (maxillary), 151S (mandibular)
    • Forceps for anteriors à no. 1
    • Root tip pick (optional)
    • «Sterile surgical gloves are required for extractions in the Pacific Pediatric Clinic

 

5)    Know the extraction techniques and instrumentation for maxillary primary anterior and posterior teeth

Maxillary Anterior

a)     All maxillary anterior teeth have a conical root shape

b)    Epithelial attachment is separated with periosteal elevator or curette

c)     No. 1 forceps is seated apical to the height of contour of the crown

d)     Free hand fingers are place on the buccal and palatal alveolar bone

e)     Slow, constant rotational force is applied

f)     Only after tooth is well luxated is an extrusive force applied

g)     DO NOT compress alveolus following tooth removal

 

Maxillary Posterior

a)     Epithelial attachment is separated with periosteal elevator or curette

b)    Tooth is luxated with a straight elevator à adequate luxation can lessen probability of separated root tips or make removal of root tips easier

c)     No. 150S forceps are seated apical to height of contour of the crown

d)     Free hand fingers are placed on the buccal and palatal alveolar bone

e)     Palatal movement is initiated first, followed by alternate buccal and palatal movements

f)     NO rotational forces are applied

g)     Only slow, continuous forces are applied to expand the bone and prevent root fracture

h)     DO NOT compress alveolus following tooth removal

 

6)    Know the extraction techniques and instrumentation for mandibular primary anterior and posterior teeth

          Mandibular Anterior

a)     All mandibular anterior teeth have a conical root shape

b)    Use free hand to support the mandible, as well as mouth prop (« Molt Prop®) to prevent TMJ injury

c)     Epithelial attachment is separated with periosteal elevator or curette

d)     No. 1, 44S, or 20 forceps is used to apply rotational forces (crowding may indicate use of buccal and lingual forces prior to rotational forces)

e)     Extrusive forces are applied after the tooth is thoroughly luxated

f)     Take care not to luxate adjacent teeth

g)     DO NOT compress alveolus following tooth removal

Mandibular Posterior

a)     Use free hand to support the mandible, as well as mouth prop (« Molt Prop®) to prevent TMJ injury

b)    Epithelial attachment is separated with periosteal elevator or curette

c)     Tooth is luxated with a straight elevator

d)     No. 151S forceps is used to provide slow, continuous buccal and lingual forces

e)     Extrusive forces are applied after the tooth is thoroughly luxated

f)     DO NOT compress alveolus following tooth removal

 

7)    Discuss the avoidance and management of primary root fractures resulting from extractions

Common Etiologies

s Internal or external root resorption

s Ankylosis of tooth being extracted

s Failure to adequately elevate before using forceps

s Root fracture secondary to trauma

Sequele of Separated Root

s May become source of post-operative infection (abscess)

s May erupt with the permanent tooth as a sequestrum

s May resorb normally (most common outcome)

Removal of Separated Root

s Attempt to remove when clearly visible and accessible

Considerations for Leaving Separated Root

s After several failed attempts (firmly embedded)

s Damage to underlying permanent tooth is likely if removed

Follow-Up for Un-removed Separated Root

s Post-operative radiograph and clear chart entry

s Explanation to parents regarding signs of abscess

s Monitor at subsequent patient visits

 

8)    Discuss the prevention of aspiration during primary tooth extraction

Caution patient to avoid swallowing

Gauze screen (“tooth net”) made from unfolded 2x2 gauze placed distal to the tooth being extracted

Upright positioning («NOT used in Pacific Pediatric Clinic)

 

9)    Discuss the management of suspected aspiration during primary tooth extraction

Fragment Location

Action Taken

Patient’s Mouth

Turn patient onto left side and retrieve

Aspiration is more likely via right mainstem bronchus in small children

Not Retrieved

Order a chest film immediately with request to locate foreign object

GI Tract

Should be expelled with time

Respiratory Tract

Must be retrieved endoscopically

 

10) Discuss post-operative instructions that should be given to the patient and his/her parent(s)

¨      Have patient bite on gauze for 30 minutes (avoid chewing)

¨      Remind patient (and parent) to avoid lip/cheek biting («Patients get a sticker at Pacific Pediatric Clinic)

¨      Patient is to brush daily
          1st day à rinse mouth to clean
          After 1st day à resume brushing with rinsing

¨      Remind parents that bleeding stimulates saliva, which can give the appearance that bleeding is more copious than it actually is

¨      Written post-operative (home language) instructions are helpful

¨      Give parents a contact number for post-operative questions/emergencies

 

11)  Describe the appropriate post-operative pain management for pediatric patients

OTC Children’s Tylenol (acetaminophen) is usually adequate

Stronger medications (Tylenol 3, etc.) are not usually necessary

 

12) Be familiar with Pacific Pediatric Clinic Policies and Procedures («) relating to extraction of primary teeth

Sterile surgical gloves

NO upright positioning

Anesthesia sticker to avoid lip/cheek biting

(additional protocols in Anesthesia portion of Fall Midterm Review)

Child Abuse

Historical Notes:

          No laws until 1960s

          1962 à Battered Child Syndrome (AAP symposium)

          1963 à First child abuse reporting law enacted in California

          1974 à Child Abuse Prevention and Treatment Act

          1994 à P.A.N.D.A Progam

 

1)      Be able to discuss the incidence, etiology and types of abuse

Incidence of Abuse

Statistics are rough approximations at best

Many reports go uninvestigated

Significant underreporting exists with many reports labeled “unfounded”

National

>3 million reported cases per year

>2000 US child deaths

18,000 now disabled

2nd only to SIDS as the greatest killer ages 1-6 months

2nd only to accidents as the greatest killer ages 1-5 years

California

>500,000 reports annually

>5,700 reports in San Francisco last year

Types of Abuse

Physical

Non-accidental injuries inflicted by a caretaker

³ Most common type of child abuse

³ Most easily detected type of child abuse

³ Recognized as one of the major causes of developmental disabilities in children

³ Often arises from an attempt to punish child

³ Can be the result of lashing out at child for unrelated event

³ Trauma to head, neck and associated areas in >50% of physical abuse cases

³ Soft tissue injury (bruises) are most common injury

³ Injuries to upper lip and/or frenum are characteristic of severely abused child

³ 35% of physically abused children returned to parent without intervention are more seriously re-injured

³ 5% of physically abused children returned to parents without intervention are later killed or die as a result of further physical abuse

Sexual

Any sexual activity with a child under the age of 18 by an adult

³ Probably the most under-diagnosed form of child abuse

³ Majority of victimized children are female

³ Majority of offenders are male

³ Affected child may show age-inappropriate seductive behavior toward adults

³ Young victims may be preoccupied with sexuality of self, parents, or other children

Emotional

Continual scapegoating and rejection of a child by parents or caretaker

³ Often difficult to detect without long term observation of child and caretaker

³ Parent/caretaker may be psychotic or severely depressed

³ May be perpetrated by teacher or other non-related significant adult

Etiology of Abuse

Abuse Incident = Right Parent + Right Child + Right Day

Abuser

2)    Be aware of the P.A.N.D.A.® Program for dental professionals

Prevent Abuse and Neglect through Dental Awareness

Established to provide education to dental professionals on how to recognize and report suspected abuse

Promote awareness of child abuse prevention

Sponsored by Delta Dental Plan of California and other professional organizations

 

3)    Know the recognizable signs and symptoms of an abused child

History

Carefully/thoroughly recorded

Include past MHx, HPInj

Parent may be vague or evasive

Parent may blame siblings

Discrepancies between versions of event

Discrepancy between version and extent of injury

History of repeated suspicious injuries

Alleged 3rd party inflicted injury

Delay in seeking care

Examination

Only to extent appropriate

Involve second party w/ suspicions, and should witness exam

Ask child for explanation

Adequate documentation is essential (photos, x-rays, models, written description)

Generally dirty, ill-kept

Dressed inappropriately for season to hide injuries

Multiple injuries in various stages of healing

Bruises in atypical locations (usually bruise at bony prominence, not in soft tissue areas)

Scars, welts, electric cord marks, hand or belt marks, burns, human bite marks

 

4)    Know the dentist’s role and responsibilities in recognizing and reporting cases of child abuse

GOAL à assist family in obtaining needed guidance in handling stress appropriately

     Dental care providers are required by law to report suspicions

     “Social Welfare Services”, “Child Protective Services”, or “Child Abuse” usually have entries in phone book

     National Child Abuse Hotline à 1-800-552-7096

     Contact local law enforcement in emergency situations

     Report must be filed within 36 hours

 

5)    Know the special treatment considerations when treating patients that you suspect of being victims of abuse

GOAL à to treat as definitively as possible on presentation b/c follow-up is unlikely once suspicions are aired

Trauma Isolated to Oral Cavity

     Provide definitive treatment à avoid temporary restorations

     Discuss treatment/prognosis/follow-up before suspicions of abuse

     Discuss suspicions of abuse last

Trauma Beyond Dentist’s Ability to Treat

     Perform needed emergency treatment

     Refer to appropriate professional

     Again, treatment and referrals made before discussion of abuse suspicions

 

6)    Know the possible sequelae of reporting child abuse

Consequences for Dentist

Immune from prosecution if report is in good faith (all 50 states)

California has funding to reimburse legal expenses for wrongful suits

Must have verifiable documentation and be willing to testify

Must be notified of outcome by investigating agency

Consequences for Family

Goal of intervention is to counsel parents

Most cases are settled through social service agencies (counseling)

Rarely are children removed from home

Removed from home if the child is in imminent danger

Placement in non-family related foster care is last resort

 

 

7)    Be familiar with common folk remedies which may be mistaken for child abuse

Dry Cupping

Small amount of alcohol poured in glass, ignited, and glass inverted onto skin

Skin is drawn up by suction created by cooling air in glass

Well circumscribed round areas of congestion on skin

Appearance is similar to bruising

Believed therapeutic for aches, pains, and respiratory congestion

Coin Rolling/Rubbing

Cao Gio

Abrasive rubbing of coin edge across oiled skin

Adapted from acupuncture

Orderly bilateral lines of ecchymosis on skin

Believed therapeutic for a number of ailments

Therapeutic Pinching

Bat Gio

Pinching of skin

Adapted from acupuncture, acupressure

Pinch marks are typically over temples, forehead and neck

Believed therapeutic for multiple ailments

Management of Folk Remedies

Respect families’ cultural beliefs

Parents may be reluctant to admit use of folk remedies

Parents may claim grandparents provided therapy

Parents should be counseled in more appropriate treatment
