Low-power laser (LL) irradiation causes biological effects such as analgesia. Cerebrospinal fluid (CSF) and blood immunoreactive Î²-endorphin (IÎ²-E) delivery is involved; however, there are no opioid doseâresponse curves for different laser energy densities (ED) irradiation. In this...
The purpose of this study was to determine the power and time parameters for an argon laser that would result in the removal of pulpal tissue without excessively elevating the external temperature of the root. External temperatures were measured by attaching thermistors to the surfaces of the...
The mechanism of postangioplasty vasospasm is uncertain. It was postulated that alterations in arachidonic acid metabolism might contribute to spasm or acute occlusion of the treated coronary artery. In this study, coronary arterial plasma prostacyclin and thromboxane were monitored before and...
In Hungary, where lasers are few and the economy dictates wise use of those that exist, it is important to emphasize the versatility of a laser to support the cost and maintenance of it. This study indicates that both the CO 2 and Nd:YAG lasers can be effective as treatment for vascular...
This clinical study examined the pulpal safety of selected CO 2 laser hard tissue applications. A total of 187 hard tissue procedures were performed on 54 patients. The mean period of follow-up following laser treatment was 13.5 months (range 2â24 months). The procedures included etching ( n...
This study investigated the effects of low-power laser irradiation on the rabbit cornea. Making use of the immune reaction common in rabbits, the Arthus phenomenon, we injected all rabbits with complete Freund's adjuvant containing inactivated mycobacterium twice to stimulate B cell activity,...
