Vertical fractures of root seen with gutta-percha obturation are due to the vertical compression of warm gutta-percha points. This occurs because: 1) Excessive vertical pressure during warm gutta-percha condensation, 2) High temperatures make the material expand and contract, creating stress, 3) Continuous downward pressure can exceed the tensile strength of dentin, 4) Thin-walled roots are particularly susceptible, 5) Over-condensation attempts to achieve dense packing. Lateral condensation and spreader use typically cause horizontal stress, not vertical fractures. Proper technique with controlled pressure helps prevent this complication.

The growth of the mandible generally follows the "general" body growth curve, which is distinct from the neural and lymphoid tissue growth curves described by Scammon's growth curves.

Lymphoid tissue grows very rapidly in childhood, reaching a peak larger than adult size before puberty, then shrinking.

Neural tissue grows rapidly early in life and reaches nearly adult size by about 6-7 years of age.

General tissues (including bone, muscle, and viscera) exhibit an S-shaped curve with rapid growth in infancy, a slower phase in childhood, and a pubertal growth spurt. The mandible's growth pattern most closely mirrors this general curve.
