Aim: The aim of the study was to evaluate the effect of mouth cleaning with hinokitiol-containing gel on oral malodor.

Methods: An open-label, randomized, controlled trial was conducted to assess oral malodor and clinical parameters related to oral malodor before and after mouth cleaning with hinokitiol-containing gel (n = 9) or with gel not including hinokitiol (n = 9). Mouth cleaning included the teeth, gingiva, and tongue and was carried out 3 times per day for 4 weeks.

Results: Organoleptic test (OLT) scores (P = .021), levels of hydrogen sulfide (P = .008) and methyl mercaptan (P = .020), frequency of bleeding on probing, average probing pocket depth, and plaque index significantly improved in the group using hinokitiol. In contrast, only the OLT score (P = .031) significantly improved in the control group after the treatment regimen.

Conclusion: Mouth cleaning with hinokitiol-containing gel may be effective for reduction of oral malodor.

We have previously demonstrated that subgingival levels of nitrate-reducing bacteria, as well as the in vitro salivary nitrate reduction capacity (NRC), were diminished in periodontitis patients, increasing after periodontal treatment. However, it remains unclear if an impaired NRC in periodontitis can affect systemic health. To determine this, the effect of nitrate-rich beetroot juice (BRJ) on blood pressure was determined in 15 periodontitis patients before and 70 days after periodontal treatment (i.

Background: It has been outlined that LTM (Lower third molar) extracted from patients in which grinding, cleaning, sterilization & demineralization prove to be highly effective as graft material for filling the alveolar socket of the very same patient. These investigations aim to assess the efficiency of ADDM (Autogenous Demineralized Dentin Matrix) graft in third molar extraction sockets.

Purpose: To check the effectiveness of ADDM as graft material in extraction socket by evaluating pain, swelling, trismus, PD (Probing Depth) and bone density.

Objectives: To compare the plaque reducing efficacy of oil pulling with sesame oil compared to distilled water in a randomized, controlled, examiner-blinded parallel group study.

Materials And Methods: Forty probands without advanced periodontal disease of the University Hospital for Restorative Dentistry and Periodontology, Medical University of Innsbruck (Austria) were randomized allocated to test- (sesame oil) or control group (distilled water) and asked to pull daily in the morning for eight weeks with their allotted fluid for 15 min. Rustogi Modified Navy Plaque Index (RMNPI) and gingival bleeding index were assessed at baseline and after four and eight weeks.
