| 總結: | The alveolar bone remodeling is the basic of the orthodontic tooth movement. Resorption in the stress area and aposisition in the tension area. Osteoclast is the resorption cell. The difference of cAMP concentration between the young and adult individu may be influences the alveolar bone remodeling. The objective of this study was to investigate the osteoclast reactivity difference between young and adult in the rat periodontal membrane.
Fourty five male Rattus 2 month of age and fourty five male rattus 7 month of age divided into 3 groups. Experimental Group, False group and control group. Mecanical tension inserted to the first right upper molar with close coil spring for about 50 gram. After one, seven and fourtheen days the animals were killed, the tooh and the supporting tissue removed for histological excaminations.
The result of the study showed there is no significant difference between osteoclastic reactivity in the young and adult rat periodontal membrane at the first day. At the seven days, more osteoclast found in the young rat and at the fourteen days, more osteoclast in the adult rat than in the young.
Key words : Reactivity, Osteoclast, Periodontal membrane, Young and adult rats, Mecanical tension |
