Abstract

Objectives

The aim of this study is to evaluate the effect of operators experience and skill on treatment results of initial non-surgical periodontal therapy.

Materials and methods

Initial periodontal treatment was carried out by either second-year periodontal residents (PR) or last year dental students (DS). From the treatment records of patients in each group, plaque and bleeding indices, and pocket depth (PD) at baseline and at re-evaluation were collected retrospectively on each tooth at six locations. Data were separated according to tooth type, area, and probing depth categories, sub-grouped to 1–3, 4–5, and ≥ 6 mm.

Results

Fifty and 49 records of DS and PR patients, accordingly, were analyzed. Initial periodontal treatment improved patient compliance in both groups and reduced signs of inflammation with significantly superior results in the PR group. Significant change in percentage of pockets was recorded in each category. The increase in percentage of sites with PD 1–3 mm and decrease in percentage of PD ≥ 6 mm pockets was significantly (p ≤ 0.001) superior in patients treated by PR. Percentage of 4–5 mm pockets was significantly reduced in both groups (p ≤ 0.01), with a significantly greater reduction in the mandibular molar and anterior teeth in the PR group.

Conclusions

Experience and skill significantly affect the outcome of non-surgical periodontal therapy, with more positive improvement in patient compliance and clinical parameters when performed by a more qualified operator.

Clinical relevance

Improvement of operator skills may decrease the number of residual pockets and increase patient compliance following non-surgical periodontal treatment.
