Comparison of dental pulp periodontal therapy and conventional simple periodontal therapy as treatment modalities for severe periodontitis

BACKGROUND: Severe periodontitis is a major oral health concern today as it can lead to loss of teeth. Conventional periodontal therapy has numerous pitfalls as it does not address the pulp-periodontal complex in its entirety. AIM: To investigate the effect of dental pulp periodontal therapy on the levels of interleukin-1β (IL-1β) and IL-10 in gingival crevicular fluid (GCF) in patients with severe periodontitis. METHODS: Eighty-six patients with severe periodontitis were randomly divided into a research group (n = 43) and a control group (n = 43). The control group was treated with simple periodontal therapy, and the research group was treated with dental pulp periodontal therapy. The total effective rates of the treatments; periodontal status before and after treatment through the measurement of the periodontal pocket probing depth (PPD), gingival sulcus bleeding index (SBI), mobility (MD), and plaque index (PLI); the levels of inflammatory factors IL-1β and IL-10 in the GCF; and the incidence of complications were calculated for both groups and compared using the Student’s t test and the χ(2) test. RESULTS: The total effective rate of treatment in the study group (93.02%) was higher than that in the control group (76.74%; P < 0.05). While before treatment, there was no significant difference in the PLI, MD, SBI, or PPD between the two groups, the post-treatment values of PLI, MD, SBI, and PPD (4.71 ± 0.16 mm, 0.61 ± 0.09 mm, 0.96 ± 0.17 mm, and 0.76 ± 0.26 mm, respectively) were significantly lower (P < 0.05) in the research group than in the control group (5.35 ± 0.24 mm, 0.93 ± 0.15 mm, 1.35 ± 0.30 mm, and 1.04 ± 0.41 mm, respectively). There was no significant difference in the level of IL-1β or IL-10 in the GCF before treatment between the two groups; after treatment, the IL-1β level in the research group (139.04 ± 15.54 pg/mL) was significantly lower than that in the control group (156.35 ± 18.10 pg/mL), and the level of IL-10 in the research group (7.98 ± 1.01 ug/L) was higher than that in the control group (5.56 ± 0.96 ug/L) (P < 0.05). The incidence of complications in the study group (4.65%) was significantly lower than that of the control group (18.60%; P < 0.05). CONCLUSION: Endodontic therapy and periodontal treatment for patients with severe periodontitis can effectively reduce the levels of inflammatory factors in the GCF and the inflammatory reaction. In addition, it can improve the periodontal condition and the overall treatment effect, reduce the risk of complications, and ensure the safety of treatment.
