Results: Data concerning the influence of OHI on periodontal features, the impact of OHI before periodontitis non-surgical treatment, its efficacity on periodontitis prevention and maintenance of healthy periodontium were summarized in the tables of the present narrative review.
Conclusion: as prevention is better than a cure, it is relevant to bring in light the role of oral hygiene instructions, the patient self-control of dental plaque as well as the professional mechanical plaque removal in the prevention of periodontitis.
