- Abstract
- Objective: The aim of this study was to evaluate the effectiveness of a novel oral irrigator (COMORALⓇ) in removing artificial dental plaque from the buccal and lingual surfaces of preformed metal crowns (PMCs).
Methods: Artificial tooth models covered with artificial dental plaque was cleaned by COMORALⓇ, equipped with a WATERETⓇ tip, at the highest pressure setting for 1 minute. The process was repeated 10 times and digital photographs were taken before and after irrigation, and the cleaned area was quantified in square pixels using image analysis software. Data were statistically analyzed using SPSS software (Version 21.0), with a significance level set at p<0.05.
Results: The COMORALⓇ showed significant plaque removal on the buccal surfaces, achieving 74.64% cleaning efficiency, with the cervical third being the most effectively cleaned area. In contrast, the plaque removal on the lingual surfaces was 24.27%, with the coronal third showing the highest cleaning efficiency. Repeated applications did not significantly improve plaque removal.
Conclusion: The COMORALⓇ effectively removes dental plaque from the buccal surfaces of PMCs, particularly in the cervical third. However, its efficiency on lingual surfaces was limited, likely due to anatomical constraints. Adjustments to the water jet angle or modifications to the WATERETⓇ tip design may enhance cleaning performance in less accessible areas. These findings highlight the potential of the COMORALⓇ as a practical adjunct to to toothbrushing, particularly for children and individuals with limited manual dexterity. - Keywords : dental plaque, oral hygiene, oral irrigator, preformed metal crown
