研究目的
To determine whether a near-infrared diode laser could be used as an adjunct to help identify and localise symptomatic cracks in patients with cracked tooth.
研究成果
The study indicated that diode laser at 1 W continuous wave setting could be used as an adjunctive tool to identify symptomatic cracks in patients presenting with cracked tooth-like symptoms. However, future research with larger participant sizes is needed.
研究不足
The study had a small participant size (twelve patients), and the risk of laser is uncertain in pregnant and breastfeeding patients, who were excluded. Also, the study did not cover other near-infrared lasers and all-current limitations.
1：Experimental Design and Method Selection:
The study used an 810-nm diode laser at 1 W continuous wave energy with a 200 micro-?bre tip to scan the offending tooth.
2：Sample Selection and Data Sources:
Patients who attended Grif?th University Undergraduate Dental Clinic, identi?ed with symptoms of cracked tooth, were invited to participate in the study.
3：List of Experimental Equipment and Materials:
An 810-nm diode laser (Picasso, AMD, IN, USA), 200-lm ?bre tip, trans-illuminator (Microlux byAdDent Inc.), and other dental diagnostic tools.
4：Experimental Procedures and Operational Workflow:
The suspected cracked tooth was scanned with the laser, and the crack identified was removed, restored, and reviewed after four weeks and after 4 years.
5：Data Analysis Methods:
Mann–Whitney U-test was used to compare the number of patients responding positively to the laser scan on suspected cracked teeth in comparison to healthy control teeth.
