• Detect oral condition with a microscope
• Used for motivating patients

8. Indigenous products:

• Use of products such as mango leaf, neem, and tea have antiplaque and anti-cariogenic potential

Question 4. Caries Vaccine.

Answer:

• It is a suspension of attenuated or killed micro organ-isms administered for the prevention, amelioration or treatment of infectious diseases.

Mechanism Of Action:

• When the tooth erupts, serum antibodies i.e. IgA stimulate opsonization and phagocytosis
• These antibodies have inhibitory effect on glucosyl-transferase and on acid production
• Results in inhibition of the metabolic activity of S.mutans on teeth

Route Of Administration:

1. Oral Route:

• Increases stimulation of IgA antibodies

2. Systemic Route:

• Subcutaneous administration of S.mutans leads to increases IgG, IgM and IgA antibodies

3. Active gingivo-salivary Route:

• Localizes the immune response by using gingival crevicular fluid as a route

4. Active Immunization:

• Synthetic peptides – Derived from glucosyl-transferase enzyme
• Coupling with cholera toxin sub-units – Coupling of the protein with a non-toxic unit of cholera toxin suppresses colonization of S.mutans
• Fusing with avirulent strains of salmonella
• Liposomes – increases IgA antibodies

5. Passive Immunization:

• External supplements include
  • Bovine milk and whey
  • Egg yolk
  • Transgenic plants

• Used primarily in chewing gums
• It reduces the transmission of cariogenic bacteria from mother to infant
• It is naturally found in fibers of many fruits and vegetables in low concentrations
• The harmful oral microbes are starved in the presence of xylitol, allowing to remineralize of damaged teeth
• Xylitol inhibits the growth of streptococcus as well as the attachment of Haemophilus on nasopharyngeal cells

Xylitol Mechanism Of Action

• Sweetness obtained from xylitol causes the secretion of saliva
• This acts as a buffer against an acidic environment created by microbes
• This raises the falling pH to a neutral range

Psychological Development And Behaviour Management Long Essays

Question 1. Explain Psychological development of a child according to Sigmund Freud.
Answer:

Sigmund Freud gave a psychoanalytical theory explaining the psychological development of a child. He describes 6 psychosexual stages and at each stage he included the development of sexual desires.

Sigmund Freu Stages:

• Oral Stage
  • It is a dependent stage where the infant depends on adults to fulfill his needs
  • But if the child’s needs are not fulfilled he develops a negative and aggressive behavior
• Anal Stage
  • During this stage, maturation of neuromuscular control occurs
  • The child obtains a sense of control over its voluntary functions, a sense of independence.
  • If it fails, the child develops abnormal behavior like stubbornness.
• Urethral Stage:
  • It is a transitional stage between the anal and a phallic stage
  • The child obtains and is satisfied with the control over its urinary sphincter
  • If it fails to develop, the child becomes competitive
• Phallic Stage:
  • Period 3rd5th year of life
  • Development of Oedipus complex and Electra complex where the young boys are attracted towards mother, while girls are attracted towards her father respec¬tively.
  • The child has unusual sexual feelings for the opposite sex
  • He carries out his sexual activities without any embarrassment
• Latency Stage:
  • This stage ends in puberty
  • A child develops a well-balanced control over his desires
  • The child adapts to the changing environment
  • Lack of this behavior results in immature behavior of the child.
• Genital Stage:
  • Period 1113 years to adulthood
  • The child realizes the sense of maturity, sense of individuality, sense of ability to reproduce, and sense of independence.
  • The child develops social environment by communicating and interacting with the surrounding
  • The child accepts the social expectations and lives according to it.

Answer:

Proposed By Freud

1. Id:

• It is basis of the pleasure principle
• It is a reservoir of desires
• It represents the mental state of the child
• It is present at birth
• The child tries completely to fulfill his desires to obtain immediate pleasure and satisfaction

2. Ego:

• It develops in the 2nd to 6th month of life
• It is based on the reality principle
• The child begins to differentiate between his dreams and his surrounding environment
• The child tries to modify his desires according to the reality

3. Superego:

• It is the restrictions on the individual which prevent him to go wrong
• It includes regulations by the parents, society, and culture
• It creates a feeling of shame and guilt on doing a wrong thing that is against the society

Question 2. Stimulus Response Theory.
Answer:

• It is a form of behavior shaping
• It is a procedure which very slowly develops behavior by reinforcing successive approximations of the desired behavior until the desired behavior is achieved.
• For example, when shaping behavior, the dental assistant or dentist is teaching the child how to behave
• Young children have to be communicative and cooperative
• Gradually the patient adapts to the procedure

Question 3. Modeling.
Answer:

• Introduced by Bandura
• It is a method of behavior modifications
• It reduces the anxiety of the child’s patient by demonstrating the same situation in a less threatening manner

Methods:

• Live models
• Filmed models
• Posters
• Audiovisual aids

Advantage: Doesn’t require any additional equipment

Requirement:

• The selection of the model should be such a person that has a greater impact on the child like siblings, parents, etc.

Question 4. Fear in Dentistry.

Answer:

Fear in an unpleasant emotion/effect consisting of psychophysiological changes in response to realistic threat or danger to one’s own experience

Dentistry Types:

1. Innate fear: Fear present since birth

Question 5. Maternal’s influence on child’s psychology.
Answer:

• There is a mother-child interdependency that initiates at infancy and builds well into the preschool period
• Bayley and Schaefer indicate that most of the relevant mother-child relationship fall into two categories

1. Autonomy versus control
2. Hostility versus love

• • Mothers who allowed enough autonomy and expressed affection had children who were friendly and cooperative and those who ignored their children did not have children who exhibited these positive behavioral features
  • Highly anxious parents tend to affect their child’s behavior negatively
  • The effect is greatest with those under 4 years of age
  • Mother-child behavior interactions

Question 6. Home.
Answer:

• It is a technique of aversive conditioning
• It was first described in the 1920s by Dr. Evangeline Jordan

Home Objectives:

• To eliminate inappropriate avoidance responses to dental treatment and to establish appropriate learned responses
• To enhance the child’s self-confidence in coping with the anxiety of dental treatment
• To ensure the child’s safety in the delivery of quality dental treatment

Home Technique:

• In this method, the dentist firmly places his hands over the child’s mouth
• Next, he kindly explains child by being close to the child’s ear
• Once desired cooperation is obtained by the child, he is complimented for his good and cooperative behavior

Home Indications:

• In the case of a healthy child who is able to understand and cooperate but who exhibits defiant, obstreperous or hysterical avoidance of behaviour to dental treatment
• For normal children who are hysterical, belligerent
• Used for children with sufficient maturity to understand simple verbal commands

Home Contraindications:

• In children who due to age, disability, medication or emotional immaturity are unable to understand and cooperate
• When it will prevent the child from breathing

Home Variations:

• Soon after eruption, they are worn down by use.

Question 7. Premature loss of deciduous teeth.

Answer:

It refers to the loss of a tooth before its permanent successor is sufficiently advanced in development and eruption to occupy its place.

• Early loss of deciduous teeth can cause migration of adjacent teeth into the space.
• This prevents the eruption of the permanent successor.
• This further leads to malocclusion.
• For example:
  • Loss of a deciduous second molar can cause a forward shift of the permanent first molar.
  • This blocks the eruption of the second premolar which results in its impaction or deflection to an abnormal position.

Question 8. Retained Deciduous Teeth.

Answer:

• It refers to a condition where there is undue retention of deciduous teeth beyond the usual eruption age of their successor.
• This prevents the normal eruption of its successor.
• Prolonged retention of deciduous anterior results in lingual/palatal eruption of their permanent successors.
• Prolonged retention of buccal teeth results in buccal/lingual eruption of their permanent succes¬sors/their impaction.

Etiology:

• Absence of underlying permanent teeth.
• Hypothyroidism.
• Ankylosed deciduous teeth.
• Non-vital deciduous teeth.

Question 9. Ankylosis.

Answer:

• It is a condition wherein a part/whole of the root surface is directly fused to the bone with the absence of the periodontal membrane.

2. Permanent Teeth

• They may exhibit variation
• Frequently seen a sequence of eruptions is:
• 6-1-2-4-3-5-7  or 6-1-2-3-4-5-7

Question 11. Submerged Teeth.

Answer:

• Teeth that is located below the occlusal plane of the rest of the teeth in the arch.
• Commonly affected teeth are deciduous teeth.
• If the permanent teeth have erupted, it locks the sub-merged deciduous molar which usually becomes ankylosed.
• If the permanent teeth has not yet erupted, it gets impacted or may erupt buccally/lingually.
• A submerged tooth occurs because of the congenital absence of an underlying tooth.

Question 12. Turner’s Tooth.

Answer:

• In case of infections affecting the deciduous teeth, it spreads to the crown of underlying permanent teeth by affecting the ameloblast cells.
• Such an affected tooth is called “Turner’s Tooth”

Development Of Dentition

Definitions

• Primate spaces/ Simian spaces / Anthropoid spaces
  • These are spaces present mesial to the maxillary canines and distal to the mandibular canines
• Incisal liability
  • The difference between the amount of space needed for the accommodation of incisors and the amount of space available is called incisal liability.
• Leeway space of Nance
  • The differences between the combined mesiodistal width of deciduous canine and molars to the combined mesiodistal width of permanent canine and premolar is called the leeway space of Nance

Development Of Dentition Important Notes

1. Gum pads

• These are alveolar processes present at the time of birth
• They are developed in two parts – labiobuccal and lingual portion
• Both parts are separated by a dental groove
• Gum pads are divided into 10 segments by a transverse groove
• The groove between the canine and first deciduous molar called lateral sulci determines inter arch relationship.

2. Shift of lower molars from flush terminal plane to Class 1 occurs by

• Early shift – by utilizing primate spaces
• Late shift – by utilizing leeway space

3. Eruption sequence of deciduous teeth

• Lower central incisor
• Upper central incisor

Development Of Dentition Short Essay

Question 1. Gumpads.

Answer:

• The alveolar processes at the time of birth are known as gum pads.
• They are pink, and firm.
• These are covered by a dense layer of fibrous periosteum.
  • Shape: They are horse-shoe-shaped.
  • Portions:
  • Gumpads divide into the labio-buccal portion and the lingual portion by a dental groove.
  • Gumpads are divided into ten segments by certain grooves called transverse grooves
  • Transverse groove between the canine and the first deciduous molar segment is called the lateral sulcus which helps in the assessment of interarch relationship.

Upper and Lower Gumpads:

• Upper gum pads is wider and longer.
• When both are approximated contact occurs in the first molar region and a space exists in the anterior region.
• This space helps in suckling.

Question 2. Terminal Plane/ Molar relationship

Answer:

The mesial-distal relation between the distal surfaces of upper and lower second deciduous molars is called the terminal plane.

Types:

1. Flush Terminal Plane:

• Here, the distal surfaces of the upper and lower second deciduous molars are in the same vertical plane.
• It is a normal feature.

2. Mesial Step:

• In this type, the distal surface of the lower second deciduous molar is more mesial to the distal surface of the upper second deciduous molar.
• Thus the permanent molars erupt directly into Angle’s class 1 occlusion.

3. Distal Step:

• Here the distal surface of the lower second deciduous molar is more distal to the distal surface of the upper second deciduous molar.
• Thus the erupting permanent molar may be in Angle’s Class 2 occlusion.

Question 3. Primate Spaces.

Answer:

• The spacing usually occurs in deciduous dentition.
• It is important for the normal development of dentition.
• The absence of these spaces leads to the crowding of teeth after the eruption of permanent teeth.
• It helps in the placement of canine cusps of opposing arches.

Site:

• Mesial to the maxillary canines.
• Distal to the mandibular canines.

Synonyms:

• Physiological space.
• Developmental space.

Question 4. Early and Late Mesial Shift.

Answer:

The shift in a lower molar from a flush terminal plane to a Class 1 relation can occur in 2 ways:

1. Early Shift:

• The forward movement of the first permanent molar utilizing the primate space is called early shift.
• The eruptive force of the first permanent molar pushes the deciduous first and second molars forward in the arch to close the primate space and thereby establish a Class 1 molar relationship.

2. Late Shift:

• Occurs in the late mixed dentition period.
• When the deciduous second molars exfoliate the permanent 1st molars drift mesially utilizing the leeway space.
• This is called a late shift.

Question5. Self-Correcting Anomalies.
(Or)
Transient malocclusions

Answer:

Question 6. Eruption and shedding sequence of primary teeth

Answer:

Eruption:

• The eruption was used to denote the tooth’s emergence through the gingiva
• Then, it become more completely defined to mean con- tenuous tooth movement from the dental bud to occlusal contact
• The order of eruption of deciduous teeth is as follows
  • Lower central incisor
  • Upper central incisor
  • Lower lateral incisor
  • Upper lateral incisor
  • First molars
  • Canines
  • Second molars

Shedding

• The physiologic process results when disturbances in the form, color, arrangement, and structure of the teeth might have occurred
• The first sign is seen in deciduous central incisors and first molars by the age of 4-5 years
• Resorption of incisors begins primarily on the lingual side while that of molars starts from the inner surfaces of the developing permanent tooth germ

Development Of Dentition Short Answers

Question 3. Ugly Duckling Stage./ Broadbent phenomenon.

Answer:

• Given by Broadbent.
• It is a transient malocclusion seen in the maxillary incisor region between 8-9 years of age.
• This is seen during the eruption of the permanent canine.
• As the developing permanent canine erupts, they displace the roots of the lateral incisors mesially.
• This transmits the forces onto the roots of the central incisor which is also displaced mesially.
• This results in midline spacing.
• This situation is so named as the child looks ugly.
• This corrects itself when the pressure is transferred from the roots to the coronal area of the incisors.

Question 4. Leeway Space of Nance.

Answer:

• The combined mesiodistal width of the permanent canines and premolars is usually less than that of the deciduous canines and molars.
• This space is called the Leeway space of Nance.

Value:

• It is greater in the mandibular arch.
• It is 1.8 mm in the maxillary arch and 3.4 mm in the mandibular arch.

Significance:

• This space is utilized for mesial drift of the mandibular molars to establish Class 1 molar relation.

Question 5. incisal Liability.

Answer:

• Permanent incisors replace deciduous incisors.
• Permanent incisors are larger ones.
• The difference between the amount of space needed for the accommodation of the permanent incisors and the place available for it is called incisal liability.

Value:

• It is a 5 mm in the mandibular arch and 7 mm in the maxillary arch.
• It is overcome by:
  • Utilization of physiologic spaces.
  • Increase in inter-canine width
  • Change in incisor inclination.

• It is a pyramid-shaped guide of healthy foods divided into sections to show the recommended intake for each food group
• The first food guide pyramid was published in Sweden in 1974.

Question 8. Molar incisor hypomineralization

Answer:

• Molar Incisor Hypomineralisation is a type of enamel defect affecting the first molars and incisors in the permanent dentition.
• It usually occurs in children under 10 years old.
• It is caused by the lack of mineralization of enamel during its maturation phase, due to interruption to the function of ameloblasts.

Features:

• MIH often presents as discoloration on one to four affected permanent molars and the associated incisors.
• The enamel of the affected teeth appears yellow, brown, cream or white and thus are sometimes referred to as ‘cheese molars’.
• There is a difference in enamel translucency in the affected teeth
• The development of tooth decay is very rapid due to the less mineralised enamel
• MIH only becomes visible once the permanent molars start to erupt

Etiology:

• Children born preterm and those with poor general health or systemic conditions in their first 3 years
• Environmental changes
• Exposure to dioxin by prolonged breast-feeding could lead to an increase in the risk of MIH
• Respiratory diseases and oxygen shortage of the ameloblasts
• Oxygen shortage combined with low birth weight
