2) Zone of hypertrophy
3) Zone of maturation
4) Zone of endochondral ossification

📝 Explanation:

Type 1 collagen is predominantly expressed in the proliferative zone of the developing secondary cartilage of the condyle.This zone is responsible for the growth of the condyle through cell division and differentiation.

If unilateral maxillary and mandibular teeth are to be extracted in one sitting, what is the recommended sequence of extraction?
1) Maxillary posteriors - Maxillary anteriors - Maxillary canine - Mandibular posteriors - Mandibular anteriors - Mandibular canine
2) Mandibular posteriors - Mandibular anterior - Mandibular canine - Maxillary posterior
3) Maxillary anteriors - Maxillary canine - Maxillary posterior - Mandibular anterior - Mandibular canine - Mandibular posterior
4) Mandibular posterior - Mandibular canine - Mandibular anterior - Maxillary canine - Maxillary anterior

📝 Explanation:

Recommended sequence: maxillary posteriors ? maxillary anteriors ? maxillary canine ? mandibular posteriors ? mandibular anteriors ? mandibular canine.

  • The recommended sequence for extracting unilateral maxillary and mandibular teeth in one sitting is typically to start with the maxillary teeth and then proceed to the mandibular teeth.
  • This approach helps prevent blood and debris from the maxillary extractions from falling into the mandibular extraction sites.
  • Within each arch, the general sequence is usually posterior teeth first, moving towards the anterior teeth, and addressing the canines in their respective positions within the sequence.
