Clinical Evaluation Of The Diode Laser In The Treatment Of Garde Ⅱ Periodontitis With Furcation Involvement

Objective To evaluate the clinical efficacy of diode laser in the treatment of class Ⅱ furcation involvement in mandibular molars.Methods 40 patients(40 teeth)with class Ⅱ furcation involvement of periodontitis were selected.One week after ultrasonic supragingival scaling was the baseline,and patients were randomly divided into two groups.The control group was treated with subgingival scaling and root planing(SRP)alone,while the experimental group was treated with 980 nm diode laser before and after SRP.After the treatment,the pain,periodontal clinical indexes and imaging indexes were compared between the two groups.Results: Both treatments significantly reduced the periodontal clinical indexes and imaging indexes in the diseased teeth with degree Ⅱ furcation involvement.The reduction of PD in the experimental group at weeks 12 and 24 was significantly than control group(P<0.05);Also,the reduction of HPD in the experimental group at 8,12 and 24 weeks after treatment was statistically compared to the control group(P<0.05).However,there was no difference in BI and CAL between the two groups(P<0.05).The VAS pain score was significantly lower in experimental group than in control group(P< 0.05).At 24 weeks,the level of BL-H in the experimental group was statistically lower than the control group(P<0.05),while there was no significant difference of BL-V between the two groups(P>0.05).Conclusion Diode laser is a safe,comfortable,and clinically effective means when assisting SRP in the treatment of class Ⅱ degree furcation disease.
