B.3.1 Freud's Psychoanalytic Theory (2 marks)

1. The unconscious mind governs much of human thought and behaviour; repressed desires and conflicts from childhood manifest as neuroses in adult life.
2. Infantile sexuality — children experience erotic drives from birth, and the way these are managed at each developmental stage shapes personality and mental health.
3. Psychic energy (libido) shifts focus from one bodily zone to another as the child develops. Unresolved conflicts at any stage result in fixation, leaving a portion of libidinal energy "stuck" at that stage and producing characteristic personality traits or disorders.

B.3.2 The Psychosexual Stages Proposed by Freud (8 marks)

1. Oral Stage (Birth – 18 months)

• Erogenous zone: Mouth, lips, tongue
• Focus: The infant's needs and pleasures are centred on oral activities — sucking, biting, chewing, and swallowing (nursing).
• Key dynamic: Libidinal (pleasure-seeking) drives dominate early on (oral erotism); aggressive components emerge later (oral sadism — biting, devouring fantasies).
• Objective: Establish trust and comfortable dependence on caregivers; express oral needs without excessive conflict.
• Fixation/Pathology: Excessive gratification or deprivation can produce traits such as excessive optimism or pessimism, narcissism, demandingness, envy, and jealousy. Oral characters are often highly dependent on others for self-esteem.
• Healthy resolution: The capacity to give and receive from others without excessive envy or dependence; basic sense of trust and self-reliance.

2. Anal Stage (18 months – 3 years)

• Erogenous zone: Anus; control of the anal sphincter
• Focus: The child gains voluntary control over bowel function. Conflicts arise around retaining or expelling faeces during toilet training, symbolising broader issues of control, autonomy, and separation from parents.
• Key dynamic: Anal erotism (pleasure in retention and the act of giving a "gift") vs. anal sadism (aggression expressed through expulsion). Ambivalence and independence strivings increase.
• Objective: Achieve autonomy and self-control without excessive shame, self-doubt, or loss of control.
• Fixation/Pathology: Maladaptive traits include obstinacy, stubbornness, orderliness, frugality (anal-retentive) or, when defences fail, messiness, cruelty, and destructiveness (anal-expulsive).
• Healthy resolution: Personal autonomy, capacity for initiative without guilt, self-determination without shame.

3. Phallic Stage (3 – 5/6 years)

• Erogenous zone: Genitals (penis/clitoris)
• Focus: The child becomes aware of the genitals. This is the stage of the famous Oedipus complex (in boys) and Electra complex (in girls).
  • Boys: Develop erotic feelings toward the mother and rivalry/hostility toward the father, accompanied by castration anxiety (fear the father will punish him by castrating him). Resolution occurs by identifying with the father and internalising his moral standards → formation of the superego.
  • Girls: Freud proposed penis envy — the girl perceives herself as already castrated and blames the mother, turning libidinal attention toward the father. Resolution is less clear-cut; the superego in girls was considered by Freud to be less fully developed.
• Fixation/Pathology: Difficulties with sexual identity, authority, rivalry, and moral development. May predispose to neuroses, phobias, or hysterical symptoms in adult life.
• Healthy resolution: Appropriate gender identification, internalisation of moral values (superego development), healthy modelling on the same-sex parent.

4. Latency Stage (6 years – Puberty)

• Erogenous zone: No new zone; sexual drives become dormant/repressed
• Focus: Sexual impulses are suppressed and channelled into socially acceptable activities — academic learning, peer relationships, sports, and the development of cognitive and social skills.
• Key dynamic: The superego becomes consolidated. The child focuses on same-sex peer groups and the acquisition of cultural and intellectual competencies.
• Fixation/Pathology: This stage is relatively free of major conflict; problems are usually carried over from unresolved earlier stages.
• Healthy resolution: Social competence, intellectual development, and ego strengthening in preparation for puberty.

5. Genital Stage (Puberty – Adulthood)

• Erogenous zone: Genitals (mature, other-directed sexuality)
• Focus: With the hormonal changes of puberty, libidinal drives re-emerge and are directed toward sexual partners outside the family. This stage involves the integration of all earlier psychosexual stages.
• Key dynamic: Successful resolution requires reintegrating and working through earlier unresolved conflicts. Freud believed that the clitoral erotism of childhood shifts to vaginal primacy in women at this stage (a view subsequently questioned by later research).
• Fixation/Pathology: Residual fixations from earlier stages impair the capacity for mature, reciprocal relationships; may manifest as sexual dysfunction, neurosis, or immature personality patterns.
• Healthy resolution: The capacity for full genital potency, mature love relationships, a stable self-concept, and a fully integrated adult personality with the ability to work and love (what Freud called lieben und arbeiten).

B.4.1 Four Components of Anticipatory Guidance for this Child (4 marks)

1. Dietary counselling — Reducing the frequency of fermentable carbohydrate intake and limiting sugary snacks/beverages between meals, since frequency of sugar exposure is more cariogenic than total amount consumed.
2. Oral hygiene instruction — Twice-daily toothbrushing with fluoride toothpaste (pea-sized amount), supervised by a parent/caregiver at this age, and introduction of flossing where contact points are present.
3. Fluoride use — Appropriate use of fluoride toothpaste, discussion of water fluoridation status, and consideration of professionally applied fluoride varnish to strengthen enamel and prevent caries.
4. Dental visit behaviour and scheduling — Establishing a dental home with regular six-monthly recall visits, discussing what to expect at dental appointments to reduce anxiety, and reinforcing the importance of routine professional care.

B.4.2 Role of Anticipatory Guidance in Preventing Dental Disease and Promoting Long-Term Oral Health in Children (6 marks)

1. Caries Prevention through Dietary Modification

• Frequency over quantity — explaining that repeated snacking prolongs acid attacks on enamel, keeping plaque pH below the critical level (5.5) for longer periods.
• Cariogenic foods — identifying sticky sweets, biscuits, fruit juices, and carbonated drinks as high-risk items and providing practical alternatives (water, cheese, raw vegetables).
• Meal structuring — encouraging scheduled meal and snack times with water between meals, reducing the number of acid challenges per day.

2. Establishment of Effective Oral Hygiene Practices

• Understand that plaque control is the primary mechanical means of caries and gingivitis prevention.
• Supervise brushing at age 5, as children lack the manual dexterity for independent effective brushing until approximately age 7–8.
• Use correct brushing technique (modified Bass or Fones method for children) twice daily with fluoride toothpaste.
• Begin interdental cleaning (flossing) once adjacent tooth surfaces are in contact.

3. Optimising Fluoride Exposure

• Systemic fluoride (fluoridated water/supplements) — incorporates into developing enamel, making it more resistant to acid dissolution.
• Topical fluoride (toothpaste, varnish, gels) — remineralises early demineralised enamel lesions and inhibits bacterial metabolism.

4. Reducing Risk Factors and Modifying Behaviours

• Oral habits — thumb-sucking, pacifier use, and mouth-breathing that affect occlusion and oral environment.
• Trauma prevention — mouthguard use during contact sports as the child becomes more physically active.
• Screen time and sleep hygiene — indirectly related to late-night snacking and sugary drink consumption patterns.

5. Early Detection and the Dental Home Concept

• Early identification of incipient (white-spot) lesions that can be reversed with remineralisation before cavitation occurs.
• Professional cleaning to remove calculus and staining that home care cannot.
• Timely referral for fissure sealants on erupting permanent first molars — a highly cost-effective preventive intervention for caries-susceptible pit-and-fissure surfaces.

6. Parental Education and Long-Term Health Promotion

• Improves parental health literacy regarding the infectious and behavioural nature of dental caries.
• Addresses transmission of S. mutans — caregivers sharing utensils or "cleaning" dummies orally can inoculate infants with cariogenic bacteria.
• Motivates role-modelling — parents with good oral hygiene and dietary habits transmit these to children.
• Builds dental self-efficacy in families, reducing dental anxiety and improving long-term compliance with professional care.
