Pedodontics

 Anomalies of Number: problems in initiation stage

 Hypodontia: 6% incidence; usually autosomal dominant (50% chance of passing to children) with variable expressivity (e.g., parent has mild while child has severe); most common missing permanent tooth (excluding 3rd molars) is Md 2nd premolar, 2nd most common is X lateral; oligodontia (at least 6 missing), and anodontia

1. Clincial implications: can interfere with function, lack of teeth → ↓ alveolar bone formation, esthetics, hard to replace in young children, implants only after growth completed, severe cases should receive genetic and systemic evaluation to see if other problems

2. Syndromes with hypodontia: Rieger syndrome, incontinentia pigmenti, Kabuki syndrome, Ellis-van Creveld syndrome, epidermolysis bullosa junctionalis, and ectodermal dysplasia (usually X-linked; sparse hair, unable to sweat, dysplastic nails)

Supernumerary teeth: aka hyperdontia; mesiodens when located in palatal midline; occur sporadically or as part of syndrome, common in cleft cases; delayed eruption often a sign that supernumeraries are preventing normal eruption

 

1. Multiple supernumerary teeth: cleidocranial dysplasia/dysostosis, Down’s, Apert, and Crouzon syndromes, etc.

Anomalies of Size: problems in morphodifferentiation stage

Microdontia: most commonly peg laterals; also in Down’s syndrome, hemifacial microsomia

Macrodontia: may be associated with hemifacial hypertrophy

Fusion: more common in primary dentition; union of two developing teeth

Gemination: more common in primary; incomplete division of single tooth bud → bifid crown, one pulp chamber; clinically distinguish from fusion by counting geminated tooth as one and have normal # teeth present (not in fusion)

 Anomalies of Shape: errors during morphodifferentiation stage

Dens evaginatus: extra cusp in central groove/cingulum; fracture can → pulp exposure; most common in Orientals

Dens in dente: invagination of inner enamel epithelium → appearance of tooth within a tooth

Taurodontism: failure of Hertwig’s epithelial root sheath to invaginate to proper level → elongated (deep) pulp chamber, stunted roots; sporadic or associated with syndrome (e.g., amelogenesis imperfecta, Trichodento-osseous syndrome, ectodermal dysplasia)

Conical teeth: often associated with ectodermal dysplasia

Anomalies of Structure: problems during histodifferentiation, apposition, and mineralization stages

Dentinogenesis imperfecta: problem during histodifferentiation where defective dentin matrix → disorganized and atubular circumpulpal dentin; autosomal dominant inheritance; three types, one occurs with osteogenesis imperfecta (brittle bone syndrome); not sensitive despite exposed dentin; primary dentition has bulbous crowns, obliterated pulp chambers, bluish-grey or brownish-yellow teeth that are easily worn; permanent teeth often stained but can be sound

Amelogenesis imperfecta: heritable defect, independent from metabolic, syndromes, or systemic conditions (though similar defects seen with syndromes or environmental insults); four main types (hypoplastic, hypocalcified, hypomaturation, hypoplastic/hypomaturation with taurodontism); proper treatment addresses sensitivity, esthetics, VDO, caries and gingivitis prevention

Enamel hypoplasia: quantitative defect of enamel from problems in apposition stage; localized (caused by trauma) or generalized (caused by infection, metabolic disease, malnutrition, or hereditary disorders) effects; more common in malnourished children; least commonly Md incisors affected, often 1st molars; more susceptible to caries, excessive wearing → lost VDO, esthetic problems, and sensitivity to hot/cold

Enamel hypocalcification: during calcification stage

Fluorosis: excess F ingestion during calcification stage → intrinsic stain, mottled appearance, or brown staining and pitting; mild, moderate, or severe; porous enamel soaks up external stain

Erikson's Eight Stages of Psychosocial Development

  1. Basic Trust versus Basic Mistrust (Hope):

    • Age: Infants (0-1 year)
    • Description: In this stage, infants learn to trust their caregivers and the world around them. Consistent and reliable care leads to a sense of security.
    • Positive Outcome: If caregivers provide reliable care and affection, the infant develops a sense of trust, leading to feelings of safety and hope.
    • Negative Outcome: Inconsistent or neglectful care can result in mistrust, leading to anxiety and insecurity.
  2. Autonomy versus Shame and Doubt (Will):

    • Age: Toddlers (1-2 years)
    • Description: As toddlers begin to explore their environment and assert their independence, they face the challenge of developing autonomy.
    • Positive Outcome: Encouragement and support from caregivers foster a sense of autonomy and confidence in their abilities.
    • Negative Outcome: Overly critical or controlling caregivers can lead to feelings of shame and doubt about their abilities.
  3. Initiative versus Guilt (Purpose):

    • Age: Early Childhood (2-6 years)
    • Description: Children begin to initiate activities, assert control over their environment, and develop a sense of purpose.
    • Positive Outcome: When children are encouraged to take initiative, they develop a sense of purpose and leadership.
    • Negative Outcome: If their initiatives are met with criticism or discouragement, they may develop feelings of guilt and inhibition.
  4. Industry versus Inferiority (Competence):

    • Age: Elementary and Middle School (6-12 years)
    • Description: Children learn to work with others and develop skills and competencies. They begin to compare themselves to peers.
    • Positive Outcome: Success in school and social interactions fosters a sense of competence and achievement.
    • Negative Outcome: Failure to succeed or negative comparisons can lead to feelings of inferiority and a lack of self-worth.
  5. Identity versus Role Confusion (Fidelity):

    • Age: Adolescence (12-18 years)
    • Description: Adolescents explore their personal identity, values, and beliefs, seeking to establish a sense of self.

    • Positive Outcome: A sense of integrity arises from a life well-lived, leading to feelings of wisdom and acceptance.
    • Negative Outcome: Regret over missed opportunities or unresolved conflicts can lead to despair and dissatisfaction with life.

 Prenatal Counseling for Dental Health

Prenatal counseling is a crucial aspect of establishing a child's dental preventive program. Initiating this process before the birth of the child allows parents to prepare for their child's health and well-being effectively. This period is particularly significant for first-time parents, as they are often more receptive to health recommendations and eager to learn how to provide the best care for their child.

Importance of Prenatal Counseling

  1. Timing: The best time to begin counseling is during pregnancy, as expectant parents are highly motivated to learn about health practices that will benefit their child.
  2. Parental Awareness: Expectant parents become acutely aware of their child's dependence on them for nurturing and health care, fostering a strong instinct to provide the best possible environment for their child.

Key Counseling Topics

  1. Parental Hygiene Habits:

    • Role Modeling: Parents should be encouraged to adopt good oral hygiene practices, as children often emulate their parents' behaviors.
    • Impact on Child's Oral Health: Discuss how parents' oral health can directly affect their child's health, including the transmission of bacteria that can lead to dental issues.
  2. Pregnancy Gingivitis:

    • Education: Inform the mother-to-be about the potential for pregnancy gingivitis, a common condition characterized by swollen and bleeding gums due to hormonal changes.
    • Myth Dispelling: Address common myths surrounding childbirth and dental health, emphasizing the importance of maintaining oral hygiene during pregnancy.
  3. Infant Dental Care:

    • Early Care: Provide a review of infant dental care practices, including:
      • The importance of cleaning the infant's gums even before teeth erupt.
      • Guidelines for the introduction of the first toothbrush and toothpaste.
      • Recommendations for regular dental check-ups starting at the age of one or when the first tooth appears.

Benefits of Prenatal Counseling

  • Improved Oral Health: By educating expectant parents about their own oral hygiene and its impact on their child, both the parents and the child can achieve better oral health outcomes.
  • Preparation for Parenthood: Counseling helps parents feel more prepared and confident in their ability to care for their child's dental health from an early age.
  • Long-term Health: Establishing good dental habits early on can lead to a lifetime of healthy oral practices for the child.
