Abstract
The aim was to assess the effect of non-surgical periodontal therapy (NSPT) with adjunct photodynamic treatment (PDT) for the management of periodontal inflammation in young electronic cigarette (E-cig) users.
Patients with periodontal inflammation were included. Patient demographics and information related to E-Cig usage were recorded. Scores of plaque index (PI), bleeding index (BI), clinical attachment loss (AL) and probing depth (PD) recorded at baseline and at 3-months' follow-up. Patients were randomly divided into test (NSPT + PDT) and control groups (NSPT) alone. Sample-size estimation was done using data from a pilot investigation and group comparisons were done. Correlation between periodontal parameters and duration of E-cig use was assessed using regression analysis models. Group-comparisons were done using the Mann Whitney U test; and logistic regression was done to correlate periodontal parameters with age, gender, frequency of vaping, number of puffs inhaled and oral hygiene maintenance protocols. Level of significance was set at P<0.01.
Twenty-three and 23 individuals were randomly allocated to the test- and control-group, respectively. At baseline, PI, BI and PD were comparable in all patients. There was a significant reduction in PI (P<0.01), BI (P<0.01) and PD (P<0.01) in the test and control groups at 3-months' follow-up when compared with their respective baseline scores. At 3-months' follow-up, there was no significant difference in PI, BI and PD among patients in the test and control groups. There was no clinical evidence of clinical AL among patients in the test- and control groups at baseline and at 3-months' follow-up.
In the short-term, PDT is as effective as NSPT for the management of periodontal inflammation in young E-Cig users.
