[Vivisection studies on the effects of unilateral tooth extraction on growth of the skull amd masticatory musculature (author's transl)].
Following up on the 1st part of this cycle of publications, the 2nd Bulletin deals with investigations on upper and lower jaw growth in the Vietnamese belly pig after extracting all teeth as they appeared in the right half of the jaw. The results showed characteristic changes on the side of the extraction compared with the skull on the other side. They also show clearly that the effects of unilateral loss of teeth on the development of the bony part of the chewing apparatus are very local. This is made evident by analysis distances measured for the 3rd and 4th upper jaw widths and the 2nd vertical height of the bottom jaw. In contrast to other authors, we found no changes in the longitudinal and lateral development of the bottom jaw. Due to the slight degree of development of the alveolar process of the bottom jaw in the region of the 1st permanent molar, a significant reduction in surface area was found when removing the 2nd molars, which was performed usually at an early point, only in the group slaughtered after 12 months.
