Abstract
Purpose
To evaluate the clinical and radiographic outcomes of diode laser and chemical disinfection in comparison to selective caries removal in management of deep carious lesions.
Methods
This study was carried on 32 patients with an age range of 18–46 years. The patients were selected from the outpatient clinics in Faculty of Oral and Dental Medicine, Misr International University and Suez Canal University. All patients were randomly divided into 4 equal groups: control group, diode laser application with an output power of 0.5-W group, 0.1-W group and chemical disinfection (2% chlorhexidine) group. Preoperative clinical assessment and radiographs were performed before intervention and then the patients received their treatment and final restorations. Follow-up with clinical assessments was performed after 3 and 6 months. Cone beam computed tomography was performed at the day of intervention and after 6 months. Clinical and radiographic data were collected, tabulated, and statistically analyzed to compare between the success rates of diode laser, chemical disinfection, and conventional selective caries removal.
Results
Results of clinical assessment for all groups have shown success rate of 100%. The remaining dentin thickness was significantly increased in all study groups after application of intervention. Also, the remaining dentin density showed significant increase in all groups, where Diode laser application with an output power of 0.1-W group was significantly higher than the Control group, with no significant difference between other groups.
Conclusions
Within the limitations of the current study, the following can be concluded: (1) Selective caries removal is the treatment of choice in management of deep carious lesions. (2) Diode laser can show promising results in terms of cavity disinfection and management of deep carious lesions. (3) Low level laser therapy can have better biomodulating outcomes on the pulpal tissue healing and repair.
