Development of occlusion

A 4-year-old child presents with spaces between their primary teeth. As a dentist, you recognize that this spacing:

• Indicates a high likelihood of malocclusion development

• Suggests potential orthodontic complications

• Is a normal finding, facilitating the alignment of future permanent teeth

• Is likely caused by oral habits like thumb sucking

Primate Spacing in Dentition typically occurs:

• Between the lateral incisor and canine in the maxillary arch

• Between the canine and first molar in the mandibular arch

• Between all primary teeth

• Both A and B

Ugly Duckling Stage of Dentition is characterized by:

• The absence of spacing in primary dentition

• The emergence of the first permanent molars

• The completion of the mixed dentition phase

• The temporary misalignment of permanent incisors

In examining a 5-year-old patient, you notice spaces between the maxillary lateral incisors and canines, and between the mandibular canines and first molars. This is identified as:

• Indicative of a developmental anomaly

• Abnormal spacing requiring early intervention

• Normal primate spacing in primary dentition

• • A sign of premature tooth eruption

  
  

The first primary teeth to appear in the human mouth are typically:

• The maxillary central incisors
  

• The maxillary first molars

• The mandibular first molars

• The mandibular central incisors

In normal occlusion, the upper teeth typically:

• Sit inside the lower teeth

• Are in direct alignment with the lower teeth

• Do not make contact with the lower teeth

• Overlap the lower teeth vertically and horizontally

The mixed dentition phase refers to a period when:

• Only primary teeth are present

• Only permanent teeth are present

• Both primary and permanent teeth are present

• No teeth are present due to shedding of primary teeth
