Summary
Nd:YAG laser treatment effectively dries weeping root canals, reducing apical oozing and inflammation. Clinical and histopathological results show significant improvement in treated teeth, leading to asymptomatic outcomes.
Area of Science:
- Endodontics
- Laser Dentistry
Background:
- Persistent apical oozing in root canals presents a clinical challenge.
- Weeping canals can lead to persistent periapical inflammation and discomfort.
Purpose of the Study:
- To evaluate the clinical and histopathological effects of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser on weeping root canals.
- To assess the efficacy of Nd:YAG laser in achieving canal dryness and reducing periapical inflammation.
Main Methods:
- Nd:YAG laser application at 15 pulses per second/1.50 watts for 2-2.5 minutes to the apical portion of weeping canals.
- Clinical evaluation of canal dryness and patient symptomatology.
- Histopathological examination of periapical lesions to assess inflammatory changes.
Main Results:
- Complete canal dryness was achieved in 82.23% of cases following Nd:YAG laser treatment.
- Most treated teeth became relatively asymptomatic post-laser application.
- Histopathological analysis revealed marked improvement in inflammatory conditions, with 60% of lased cases showing Grade 1 inflammation compared to 70% of unlased cases showing Grade 3 inflammation.
Conclusions:
- Nd:YAG laser irradiation is an effective method for managing apical oozing in weeping root canals.
- Laser treatment significantly reduces periapical inflammation and improves clinical outcomes in endodontic therapy.
