Role of Dental Implant Homecare in Mucositis and Peri-implantitis Prevention: A Literature Overview

Assessing the quality of YouTube™ videos on fixed dental implant home-care and maintenance protocols

OBJECTIVES

The implant's supporting structure differs from that of the teeth when plaque accumulates, making it more prone to inflammation and bone loss. To ensure the implant's longevity, an effective maintenance protocol should be followed. This study aimed to evaluate the information on oral hygiene procedures at home for implant-supported fixed prosthesis.

METHODS

The keywords 'cleaning dental implant,' 'how to clean dental implant,' and 'dental implant hygiene' used to search for videos on YouTube™. Following the exclusions, two researchers independently analysed the remaining 100 videos for demographic data and content usefulness.

RESULTS

In terms of usefulness score distribution, 53.52% of the videos were considered slightly useful, 38.4% moderately useful and 8.1% very useful. The video content had the least quantity of knowledge about toothpaste choice (11.1%), but the greatest quantity of knowledge on flossing (68.7%).

CONCLUSIONS

According to the study's findings, there is presently no evidence-based information on YouTube™ on dental implant oral hygiene protocols for home care procedures hygiene education. Therefore, dental care professionals should analyse the information's quality and reliability before recommending it to patients.

Plant-based oral care product exhibits antibacterial effects on different stages of oral multispecies biofilm development in vitro

Background

Excessive biofilm formation on surfaces in the oral cavity is amongst the main reasons for severe infection development like periodontitis and peri-implantitis. Mechanical biofilm removal as well as the use of adjuvant antiseptics supports the prevention of pathogenic biofilm formation. Recently, the antibacterial effect of the oral care product REPHA-OS^®, based on medicinal plant extracts and essential oils, has been demonstrated on oral pathogens grown on agar plates. In the present study, the effectiveness of the product on medical relevant oral biofilm development should be demonstrated for the first time.

Methods

An established in vitro oral multispecies biofilm, composed of Streptococcus oralis, Actinomyces naeslundii, Veillonella dispar and Porphyromonas gingivalis, was used to analyze the antibacterial effect of different REPHA-OS^® concentrations on planktonic bacteria, biofilm formation and mature biofilms. It was quantified using metabolic activity assays and live/dead fluorescence staining combined with three-dimensional confocal laser-scanning microscopy. Additionally, effects on species distribution inside the biofilm were assessed by means of quantitative real-time PCR.

Results

REPHA-OS^® showed statistically significant antimicrobial effects on all stages of biofilm development: a minimal inhibitory concentration of 5% could be detected for both, for planktonic bacteria and for biofilm formation. Interestingly, only a slightly higher concentration of 10% was necessary to completely kill all bacteria in mature biofilms also. In contrast, an influence on the biofilm matrix or the species distribution could not be observed. The effect could be attributed to the herbal ingredients, not to the contained ethanol.

Conclusion

The strong antibacterial effect of REPHA-OS^® on different stages of oral biofilm development strengthens its application as an alternative adjuvant in oral care therapies.
