Supportive periodontal therapy in moderate‐to‐severe periodontitis patients: A two‐year randomized clinical trial

Abstract

Aim Evaluate supportive periodontal therapy (SPT) consisting of oral prophylaxis with oral hygiene instructions as sole intervention (test) or combined with subgingival instrumentation removing/disrupting the subgingival biofilm (control). Material and Methods Sixty‐two treated periodontitis patients (50.97 ± 9.26 years, 24 smokers) were randomly assigned to receive, every 3 months during 2 years, either test or control treatment. Examination included periodontal probing depth (PPD), bleeding on probing (BOP) and clinical attachment loss (CAL). Generalized estimating equations were used for analyses. Results Baseline demographics and smoking were similar between groups. However, at baseline, mean PPD was greater in test group than in control group (2.32 mm vs. 2.17 mm, p = .03), but similar after 2 years (2.23 mm vs. 2.15 mm, respectively). With time, significant PPD and BOP decrease and CAL increase were observed although without significant differences between groups. At sites ≥ 5 mm, PPD decrease was greater in test group than in control group irrespective of sex and smoking habit (p = .034). The distribution of sites gaining or losing attachment ±2 mm was similar between groups. Conclusion Oral prophylaxis with oral hygiene instructions alone or in combination with subgingival instrumentation was able to maintain the previously obtained periodontal condition to a comparable extent during 2 years of SPT.

Oral health‐related quality of life during supportive periodontal therapy: results from a randomized clinical trial

“…Thus, these results reflect clinically important OHIP-14 changes, even considering the low scores of the OHIP-14 questionnaire at baseline. Low scores at baseline and the last evaluation in both groups reflect clinical results achieved during the SPT period, as shown in Angst et al (2019).…”

“…Sixty-two participants composed the consecutive sample of the SPT study. Clinical data from SPT interventions have been published previously (Angst et al, 2019). Briefly, at baseline, starting 3 months after the end of the active periodontal therapy, participants were randomly allocated to receive oral prophylaxis (supragingival debridement of any calculus/biofilm up to the gingival margin and dental polishing) with oral hygiene instructions as sole intervention (test) or combined with subgingival instrumentation removing the subgingival biofilm (control).…”

“…Clinical data of the SPT study were recorded as previously published (Angst et al, 2019). At baseline, data on sociodemographic characteristics such as age, gender, smoking habits and socioeconomic status were collected as well.…”

“…Therefore, OHRQoL was included in an RCT of two types of supportive periodontal therapy (SPT) over 2 years resulting in no significant clinical differences between treatment modalities (Angst et al, 2019). The aim of the present study was twofold: (1) to evaluate possible differences in the impact of the two types of SPT interventions on OHRQoL scores of patients, over 2 years of follow-up, under the hypothesis that both treatments would promote similar results, and (2) to study the impact of periodontal diagnosis stage III and IV on OHRQoL scores after 2 years of SPT.…”

“…1,2 Despite the reduction in dental caries levels due to preventive interventions, the incidence of periodontal diseases remains high 3,4 and these conditions are highly associated with poor oral health status. [5][6][7] It is well established also that adequate oral hygiene…”
