Brief Summary

By World Health Organization (WHO) definition overweight (body mass index (BMI) \>24.9) and obesity (BMI \>29.9) are defined as abnormal or excessive fat accumulation with many possible impacts on individual's health. Association between obesity and associated metabolic syndrome (obesity, hypertension, diabetes mellitus type 2 and dyslipidemia) and oral health has become clear from several studies that proved increased odds of obese patients for developing of caries-related pathologies and periodontal disease. Periodontal disease, a major cause of tooth loss in adults, is an inflammatory disease of periodontal tissue that is initiated by dental plaque bacteria and is modulated by the inflammatory-immune host response factors. Relation between periodontal disease and obesity is bi-directional, through sharing of several proposed local and systemic pathogenesis mechanisms. For treatment of obesity, bariatric surgery (BS) procedures are methods of choice, when other less invasive options fail. They are safe, cost-effective, improve overall health and increase life expectancy. There are several types of BS interventions and most commonly performed BS is laparoscopic sleeve gastrectomy and with second most often, Roux-en-Y gastric bypass. Studies on influence of BS on periodontal health showed diverse results, with some showing no effect, while others demonstrated an increase in the prevalence of periodontitis as well as a further deterioration of periodontal tissues after BS procedure. However, studies on the prevalence of gingivitis, a reversible plaque-induced inflammation of gingiva, and its progression to periodontitis in BS patients is lacking. Furthermore, dental and periodontal status are not routinely evaluated in patients before or after BS. To the best of our knowledge studies on the effect of periodontal therapy before BS are lacking.

Full mouth debridementSupragingival plaque/calculus removal

Patients with gingivitis in the test group will be treated with supragingival debridement and with probiotic lozenges with strains of Lactobacillus brevis and Lactobacillus plantarum once a day for 3 months and in the control group by low-intensive supragingival plaque removal, as a placebo treatment, and placebo probiotics lozenges.
