Dental pulp tissue is a highly specialized conneclive tissue contains a formative
and protective cells that can be affected easily by stimuli such as occlusal trauma
subjected by occlusal overhang filling.
Sixteen albino rats aged range (6-8 months) weight range (0.5-0.75 kg) were
subjected the occlusal overhang filling made for upper first molar for 2 periods, and
according the periods, rats divided in the 2 groups. Groups I (8rats) subjected for
occlusal trauma for 2 weeks duration group II (8rats) subjected for occlusal trauma for
8 weeks duration. Histological evaluation have been done for 2.8 weeks using
hematoxyline and eosin stain.
Occlusal trauma for 2 weeks in group I showed wide irregular predentin formation
will displacement in odontoblast cell.
While in group II for 8 weeks duration, histological feature for pulp tissue showed
hyalinization (50-95 μm) in length.
Occlusal trauma for long period cause hyalinization of pulp tissue that negatively
influence on endodontic treatment in future.
