SRP With Adjunctive Use of Essential Oils – Microbiological Results
Objectives: The aim of the study was to find out if scaling and root planing (SRP) benefits from the additional use of essential oils (Cymbopogon flexuosus oil, Thymus zygis oil, Rosmarinus officinalis leaf oil) after the procedure from the microbiological point of view in a 6-months-study.
Methods: In the randomized clinical trial participated finally 46 volunteers (40-65 years old) with generalized moderate chronic periodontitis, a minimum of 20 teeth and PD between 4 and 6 mm. The participants underwent a full-mouth SRP. The volunteers rinsed their oral cavity with Parodolium® mouthwash (Symbio Vaccin, Herborn, Germany) at the end of the SRP in the test group. During the first two weeks after SRP the oral cavity was rinsed with five drops in a glass of water for sixty seconds twice daily. A blinded placebo provided by the manufacturer was used for rinsing in the control group. Clinical variables were recorded. An appointment of supportive periodontal therapy took place three months after SRP.
Samples of the subgingival biofilm were collected at baseline as well as after 3 and six months. These samples were semiquantitatively analyzed (PCR, ParoCheck® kit, Greiner Bio-One, Frickenhausen, Germany) for Tannerella forsythia, Porphyromonas gingivalis, Treponema denticola, Prevotella intermedia, Parvimonas micra, Campylobacter rectus/showae, Fusubacterium nucleatum, Aggregatibacter actinomycetemcomitans, Eikenella corrodens and Actinomyces viscosus.
Results: C. rectus was significantly reduced in both groups after three months (pt = 0.002, pc = 0.012). So also did P. micra (pt = 0.035, pc < 0.001) and T. forsythia (pt = 0.012, pc = 0.008). T. denticola was also reduced in both groups after 3 months (pt = 0.057, pc = 0.004) but with significantly higher reduction in the test group (p = 0.044). F. nucleatum was significantly more reduced in the test group than in the control group after three months (p = 0.029). After six months T. forsythia was still reduced in the test group, but not in the control group, with significant diffenrence at intergroup comparison (p = 0.039).
Conclusions: The adjunctive use of a mouthrinse containing essential oils following SRP has beneficial effects not only on clinical variables but also on microbiological variables of the subgingival biofilm.
