Questions and Answers

What are the three factors that determine the effect of oral habits on the dentition?

Intensity, duration, and frequency.

What are some examples of oral habits mentioned in the text?

Thumb sucking, tongue thrust, mouth breathing, lip biting, and bruxism.

What are the three phases of thumb and finger habits in children?

Phase 1 (newborn-2 years), Phase 2 (3-5 years old), Phase 3 (6-12 years old).

What are some etiological factors for thumb and finger sucking habits in children?

Feeding problems, physiological exploration, imitation, seeking attention, and emotional problems. Signup and view all the answers

Explain malocclusion and its impact on oral health.

Malocclusion is a condition where there is a deviation from the normal relationship of teeth to other teeth in the same arch and/or opposing arch. It can impact oral health by causing problems with chewing, speech, and oral hygiene, as well as leading to dento-facial abnormalities. Signup and view all the answers

What is the focus of preventative orthodontics and what does it entail?

Preventative orthodontics focuses on the recognition, prevention, treatment, and elimination of factors involved in the production of oral and dento-facial abnormalities. It entails addressing issues related to normal dentofacial growth, early deviation recognition, etiological factors in malocclusion, harmful oral habits, cases requiring early intervention, and determining proper timing of treatment.

What are the considerations in deciduous dentition related to premature extraction of primary teeth?

Considerations include the necessity for provision of a space maintainer in cases of early loss of primary molars, the minimal effect of early loss of anterior primary teeth on permanent teeth arrangement but potential development of oral habits like tongue thrusting, and the impact of poor restoration or loss of contacts due to caries on arch length.

Study Notes

Factors Determining Oral Habits Effect on Dentition

Intensity of the oral habit plays a significant role in impact severity.
Duration of the habit influences potential for dental alignment issues.
Frequency of the habit occurrence contributes to potential changes in dentition.

Examples of Oral Habits

Thumb sucking
Finger sucking
Lip biting
Tongue thrusting

Phases of Thumb and Finger Habits in Children

Initial Phase: Begins in infancy, typically includes reflexive sucking.
Transitional Phase: Occurs in early childhood, where sucking becomes more deliberate.
Habitual Phase: Develops as the habit becomes established and may persist without any reflexive need.

Etiological Factors for Thumb and Finger Sucking

Stress or anxiety in children can trigger these sucking habits.
Oral-facial dysfunction or discrepancies may lead to the development of habits.
Parental behaviors and family dynamics can play a role in habit formation.

Age Impact on Thumb Sucking

Stopping thumb sucking typically poses minimal risk to occlusion if ceased by age 4.

Malocclusion and Its Impact on Oral Health

Malocclusion refers to misalignment of teeth and jaws, leading to functional and aesthetic issues.
Can cause difficulties in chewing, speech, and increased risk of dental caries and periodontitis.

Focus of Preventative Orthodontics

Aims to prevent future dental issues by addressing harmful oral habits early.
Involves early diagnosis, guidance for proper dental development, and education for caregivers.

Considerations for Deciduous Dentition and Premature Extraction

Premature extraction can lead to space loss, causing future alignment problems of permanent teeth.
Consideration is necessary to maintain arch integrity and avoid malocclusion.

Treatment for Cross Bites in Deciduous Dentition

Treatment is often not necessary for cross bites if no functional issues are present by the age of 7-8.

Consequences of Over Contoured Posterior Contact Areas

Can result in occlusal discrepancies, leading to uneven wear and potential for malocclusion.
May increase risk of periodontal issues due to altered bite forces and stress distribution.
