This can be challenging and the advantages of a dental endoscope (PE) seem obvious, but they have not yet been investigated in detail. Moreover, the influence of the operators' experience and training with such a device on treatment results is unclear. Therefore, we investigated in an in-vitro study the use of PE for scaling and root planing (SRP), influenced by the operators' experience and training. Material and Methods: A sonic device and mini-Gracey curettes were used by eleven operators (six dentists, five dental hygienists) in periodontitis manikin heads (28 maxillary/mandibular teeth with artificial subgingival hard deposits and a mean attachment loss of 5.86mm ±2.12mm SD). The time required for treatment and the proportion of simulated hard deposits removed by SRP were measured. Significant differences were tested with the Kolmogorov-Smirnov, Shapiro-Wilk, or Chi Square test, and possible associations with Pearson correlation and Spearman's rank correlation (all tests double sided; p≤0.05). Results: Using PE led to a significant difference in the removal of simulated hard deposits [%] (mean±SD) irrespective of the operators' experience (PE: 90.78±12.10% [range: 58.80-100%]; nPE: 79.98±22.15% [range:38.10-100%]; p AID - 857791
