Abstract
The Purpose of this study was to examine dentin surface changes of extracted sound
third molar specimens which were etched with 10% maleic acid and irradiated at 7 -
140 /§² with CO2 and at 156 - 280 J/§² with Nd:YAG laser.
The results were as follows.
1. Dentin surfaces etched with 10% maleic acid and then irradiated at below of 42J/§²
with CO2 laser showed the retentive morphology for resin restoration.
2. Dentin surfaces irradiated at below of 42J/§² with CO2 laser showed
the increased acid-resistance.
3. Dentin surfaces irradiated at 218 - 280J/§² with Nd:YAG laser showed the retentive
morphology.
4. Dentin surfaces irradiated at 218 - 280J/§² with Nd:YAG laser and etched 10% maleic
acid and then 218 - 280/§² with Nd:YAG laser showed the increase acid-resistance.
