Abstract:

Objective To observe the systemic acute inflammatory reaction after full-mouth subgingival scaling and root planning (FM-SRP) or quadrant subgingival scaling and root planning (Q-SRP) in patients with moderate or severe periodontitis. Methods Twenty patients with moderate or severe periodontitis were randomly divided into FM-SRP group and Q-SRP group (n=10). The baseline clinical parameters of plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD) and clinical attachment loss (CAL) were measured and compared. Serum C-reactive protein (CRP) was detected before and 2 h after scaling. Questionnaire survey was conducted to record the gingival pain during and after operation, the use of analgesic drugs and the conditions of acute inflammatory reaction such as fever. Results There was no significant difference in the baseline clinical parameters between the two groups (P>0.05). There was no significant difference in CRP levels between FM-SRP group and Q-SRP group before scaling [(3.17±0.54) mg/L vs (3.42±0.71) mg/L] and 2 h after scaling [ (3.17±0.54) mg/L vs (3.46±0.83) mg/L](P>0.05), and there was no significant change after scaling within groups (P>0.05). Questionnaire survey revealed that there was no significant difference in operative and postoperative reactions between groups, and there was no significant changes after scaling within groups (P>0.05). Conclusion Both FM-SRP and Q-SRP may not lead to systemic acute inflammatory reaction in patients with moderate or severe periodontitis, and proper subgingival scaling modality may be chosen according to the clinical practice.
