Periodontal Treatment Outcome of Smokers Performed by Undergraduate Students
Objectives: The outcome of non-surgical periodontal treatment and supportive periodontal therapy (SPT) of patients with a smoking habit by 4th and 5th year undergraduate students at dental school of the University-Hospital Hamburg Eppendorf (UKE), Germany should be evaluated regarding clinical risk parameters.
Methods: Between 2015 and 2018, a total of 239 patients received non-surgical periodontal therapy as well as regular SPT by dental students (mean observation time 1.5y). The patients records were re-examined regarding their sex (M-male, F-female), age, smoking habit (SM-smoker, FS-former smoker, NoS-no smoker), number of teeth, extractions, bone loss per age (BLA), pockets with bleeding on probing (BOP) and pockets with probing depths of 5 mm and higher (PPD5). Data were assessed for each patient at baseline (T0=before therapy) and at the last documented SPT (T1). Statistically significant differences between the groups were calculated (ANOVA, α=0.05).
Results: 92 (38%) of the patients were SM (32 F/ 60 M, Ø52.5y), 10 (4%) FS (5 M/ 5 F, Ø61.2y) and 137 (58%) NoS (66 M/71 F, Ø 57.8y). 4 patients stopped smoking during treatment. NoS and FS groups were concluded as NoFS. Smokers were highly significant younger than the non-smoking group (p<0.001). At T0 the number of teeth was 22.1±5.9 for SM and 23.2±5.6 for NoFS. Until T1 2.6±3.3 teeth were extracted for SM and 1.7±2.9 teeth for NoFS.A significantly (p<0.01) higher BLA was found for SM (0.66±0.47) compared to NoFS (0.50±0.41). At T0 BOP turned out to be significantly higher (p<0.05) for NoFS (30.5±24.8%) than for SM (23.1±19.1%).Until T1 ΔBOP decreased for both groups and remained significantly higher (p<0.05) for NoFS (NoFS 18.4±24.4%, SM 12.6±21.4%). Reduces of 10.8±13.5% for NoFS and of 14.6±18.4% for SM were achieved for ΔPPD5. At T1 5.3±15.9% of the pockets remained over 5mm for NoFS and 6.4±21.7% for SM.
Conclusions: Overall periodontal treatment by students improved the clinical parameters. Smokers had a higher bone loss level and were younger when they received periodontal treatment.
