Abstract

Localization of chondroitin sulphates in periodontal ligaments (PDL) of rat molar roots during physiological and experimental tooth movement were analysed immunohistochemically with the use of monoclonal antibodies, 3B3 and 2B6, specific to chondroitin 6-sulphate (CH-6S) and chondroitin 4-sulphate/dermatan sulphate(CH-4S/DS), respectively. The maxillary first molars of experimental animals were forced to move laterally with a 10 g weight by U-shaped wires for 3 and 7 d. In control animals, 3B3 epitope was seen in the PDL near to the bone surface facing the distal half of roots, which corresponded to the compressive side during physiological tooth movement. Immunoreactivity for 2B6 was weak or negative in the PDL. Both epitopes were present at osteoid, precementum, lacunae and canaliculli of osteocytes and cementocytes. In 3-d-treated animals, the early stage of hyalinization characterized with visible cells and fibres was observed in the PDL at the buccal side of the mesial root, which showed intense immunoreactivity for 3B3. Further 3B3 positive area seen in control animals changed its position from the distal to the buccal side of the PDL. Immunoreactivity for 2B6 did not change in the PDL of 3-d-treated animals. In 7-d-treated animals, the typical hyalinization characterized with no visible cells and fibres was seen in the PDL at the buccal sides of both mesial and disto-buccal roots, where both epitopes were present at the peripheral part of the tissue. Observation of serial sections suggested that the 3B 3-positive area was present at the peripheral part of the 2B6-positive area. The present results suggest that the expression of CH-6S is related to the compressive force in non-hyalinized and hyalinized PDL, whereas that of CH-4S/DS is not influenced by the mechanical stress.
