Abstract
PURPOSE To determine the effect of Cystus® tea (Naturprodukte Dr. Pandalis GmbH & Co. KG) as mouthwash compared to sage tea on oral mucositis in patients undergoing radio(chemo)therapy for head and neck cancer. METHODS In this randomized, prospective phase III study, 60 head and neck cancer patients with primary or postoperative radio(chemo)therapy were included between 04/2012 and 06/2014. They received either sage or Cystus® tea for daily mouthwash under therapy. Mucositis was scored twice a week following the Radiation Therapy Oncology Group and the European Organization for Research and Treatment Cancer (RTOG/EORTC) scoring system. Dental parameters were also recorded. Statistical evaluation of the primary endpoint was performed using t‑test and log rank test. RESULTS Data from 57 patients could be evaluated. Patient characteristics showed no significant difference between the two groups (n = 27 sage; n = 30 Cystus®). A total of 55 patients received the prescribed dose (60-66 Gy postoperative; 70-76.8 Gy primary). Mucositis grade 3 was observed in 23 patients (n = 11 sage; n = 12 Cystus®) and occurred between day 16 and 50 after start of therapy. There was no significant difference between the two groups in latency (p = 0.75) and frequency (p = 0.85) of the occurrence of mucositis grade 3. The self-assessment of the oral mucosa and the tolerability of the tea also showed no significant differences. Occurrence of dental pathologies appeared to increase over time after radiotherapy. CONCLUSION Cystus® and sage tea have a similar effect on the occurrence of radiation-induced mucositis regarding latency and incidence. Cystus® tea mouthwash solution is tolerated well and can be applied in addition to intensive oral care and hygiene along with the application of fluorides.

Abstract
INTRODUCTION Stomatitis is a frequent adverse event in patients undergoing chemotherapy for breast cancer. Stomatitis can hamper oral nutrition resulting in malnutrition, reduce quality of life and introduce the need for dose reductions and interruption of chemotherapy; however, there is currently no standard approach for preventing chemotherapy-induced stomatitis. We aimed to assess the safety and efficacy of a dexamethasone-based elixir mouthwash for preventing chemotherapy-induced stomatitis in patients with early breast cancer. METHODS AND ANALYSIS In this multicenter, randomised, controlled phase 2 trial, we will randomly assign 120 women with early breast cancer undergoing chemotherapy to use of a dexamethasone-based elixir or standard oral care, to compare their preventive effects on chemotherapy-induced stomatitis. Patients will be assigned in a 1:1 ratio. Patients in the intervention group will receive chemotherapy, oral care and a dexamethasone-based elixir (10 mL 0.1 mg/mL; swish for 2 min and spit, four times daily for 9 weeks), and patients in the control group will receive chemotherapy and oral care. The primary endpoint is the difference in incidence of stomatitis between the two groups. The sample size allows for the detection of a minimum difference of 20% in the incidence of stomatitis between the two groups. Secondary endpoints are severity of stomatitis, duration of stomatitis, completion rate of chemotherapy and adverse events. ETHICS AND DISSEMINATION All participants signed a written consent form, and the study protocol has been reviewed and approved by the Clinical Research Review Board of Nagasaki University (CRB7180001). TRIAL REGISTRATION NUMBER UMIN Clinical Trials Registry (UMIN000030489).

A Fatty Acid Mouth Rinse Decreases Self-Reported Hunger and Increases Self-Reported Fullness in Healthy Australian Adults: A Randomized Cross-Over Trial.
Costanzo, A, Russell, CG, Lewin, S, Keast, R
Nutrients. 2020;(3)
Abstract
Fatty acid (FA) chemoreception in the oral cavity, known as fat taste, may trigger a satiety response that is homologous to FA chemoreception in the gastrointestinal tract. In addition, individuals with an impaired fat taste sensitivity are more likely to have an impaired satiety response. This study aimed to assess the effect of an FA mouth rinse on self-reported appetite, and to determine if the effect is modified by fat taste sensitivity. Thirty-one participants (age, 32.0 ± 8.4 y; body mass index (BMI), 26.1 ± 8.1 kg/m2) were studied on four separate days to evaluate the effect of a 20 mM oleic acid (OA) mouth rinse (in duplicate) compared to a control (in duplicate) on self-reported appetite by using a visual analogue scale (VAS) every 30 min for three hours following a standardized low-fat breakfast. The area under the curve ratings for fullness were greater (p = 0.003), and those for hunger were lower (p = 0.002) following the OA rinse compared to the control. The effect of the OA rinse was greater in individuals who were hypersensitive to fat taste compared to moderately sensitive and hyposensitive individuals for fullness (p < 0.010) and hunger (p < 0.010) ratings. In summary, an OA mouth rinse decreases self-reported hunger and increases self-reported fullness, particularly in those who are more sensitive to fat taste. FA receptors in the oral cavity may be potential targets to regulate appetite.

Lassmann-Klee, PG, Lindholm, T, Metsälä, M, Halonen, L, Sovijärvi, ARA, Piirilä, P
Scandinavian journal of clinical and laboratory investigation. 2018;(1-2):153-156
Abstract
Fractional exhaled nitric oxide (FENO) assesses eosinophilic inflammation of the airways, but FENO values are also influenced by oral nitric oxide (NO). The aim of this pilot study was to measure FENO and compare the effect of two different mouthwashes on FENO and analyse the duration of the effect. FENO was measured in 12 randomized volunteers (healthy or asthmatic subjects) with a NIOX VERO® analyser at an expiratory flow rate of 50 mL/s. After a baseline measurement, a mouthwash was performed either with tap water or carbonated water and was measured during 20 min in 2 min intervals. The procedure was repeated with the other mouthwash. We found that both mouthwashes reduced FENO immediately at the beginning compared to the baseline (p < .001). The carbonated water mouthwash effect lasted 12 min (p ranging from <0.001 to <0.05). The tap water mouthwash reduced FENO statistically significantly only for 2 min compared with the baseline. We conclude that a single carbonated water mouthwash can significantly reduce the oropharyngeal NO contribution during a 12 min time interval.

Uribe-Fentanes, LK, Soriano-Padilla, F, Pérez-Frutos, JR, Veras-Hernández, MA
Revista medica del Instituto Mexicano del Seguro Social. 2018;(1):98-105
Abstract
BACKGROUND Calendula officinalis is a phytodrug used as analgesic, antiseptic and wound-healing agent due to its collagenogenic effect, which is why it is a convenient and affordable treatment that promotes alveolar bone preservation after tooth extraction in vivo. The aim of this study was to use Calendula officinalis during and after tooth extraction to determine its ability to preserve bone after this procedure. METHODS We established two groups matched by age, gender and position of the third molar. We used with patients on the experimental group Calendula officinalis diluted 10% as an irrigant during surgical extraction of third molars. We performed the conventional way with the control group irrigating with saline solution. Subsequently, both groups continued to make mouthwash for a week with the irrigating agent. Every week for a month, each patient underwent periapical radiography, out of which we took measurements of alveolar ridges and depth of alveolar bone, which were compared. CONCLUSIONS There is statistically significant evidence to state that Calendula officinalis favorably affects bone preservation after extraction.

Abstract
OBJECTIVES To investigate the effects of Matricaria recutita and Mentha piperita on oral mucositis (OM) in patients undergoing hematopoietic stem cell transplantation (HSCT). DESIGN Randomized double blind placebo controlled clinical trial. SETTING Faculty of Pharmacy, Shahid Beheshti University of Medical Sciences, and Bone Marrow Transplantation Center at Taleghani Teaching Hospital, Tehran, Iran. PARTICIPANTS Sixty patients undergoing HSCT were randomly assigned to two groups: placebo (n=33), and herbal mouthwash group (n=27). INTERVENTIONS All patients received the mouthwash one week before HSCT and were instructed to use it three times daily for at least 30s. MAIN OUTCOME MEASURES OM was graded using National Cancer Institute Common Toxicity Criteria (NCI-CTC) scale (grade 0-5). The Numerical Rating Scale (NRS: 0-10 scale) measured the severity of OM symptoms. RESULTS The duration, maximum and average daily grade of OM were significantly reduced in the treatment group (P<0.05). The use of herbal mouthwash led to significant improvements in pain intensity (P=0.009), dryness (P=0.04) and dysphagia (P=0.009). Other significant results included: reduced need for complementary medications (P=0.03), narcotic analgesics (P=0.047), total parenteral nutrition (TPN) (P=0.02) and the duration of TPN (P=0.03). CONCLUSION This study shows that patients receiving the herbal mouthwash experienced less complications and symptoms associated with OM. In summary, it seems that the use of our prepared herbal mouthwash is beneficial for patients undergoing HSCT.

Schweizer Monatsschrift fur Zahnmedizin = Revue mensuelle suisse d'odonto-stomatologie = Rivista mensile svizzera di odontologia e stomatologia. 2011;(11):1041-51
Abstract
The aim of the study was to evaluate the efficacy of Parodontax® (GlaxoSmith-Kline, Bühl, Germany) on the signs gingival inflammation and the enzyme activity of matrix metalloproteinase-8 (aMMP-8) in the gingival crevicular fluid. After approval by the ethics commission, a total of 50 volunteers participated in the study; group 1 (n = 25, age: 43 ± 12 years) with moderate gingivitis (BOP +) and group 2 (n = 25, age: 29 ± 11 years) with clinically healthy gingival conditions (BOP -). After obtaining anamnestic data, the dental examination included assessment of oral hygiene (Quigley & Hein 1962), gingival inflammation (Saxer & Mühlemann 1975), probing pocket depth and clinical attachment level. Gingival crevicular fluid was collected from both groups. A quantitative assessment of aMMP-8 in the gingival crevicular fluid samples was performed (DentoAnalyzer, Dentognostics GmbH, Jena, Germany). Study participants were instructed to use only Parodontax®. After three weeks, all parameters were measured again. The aMMP-8 values of group 1 were significantly reduced after the use of Parodontax® toothpaste and mouthwash (p < 0.001; baseline median 41.25 ± 38.16 ng/ml, final post-treatment median 7.73 ± 7.58 ng/ml aMMP-8 eluate; group 2: baseline median 3.75 ± 3.16 ng/ml, final post-treatment median 3.73 ± 1.54 ng/ml aMMP-8 eluate). Gingival inflammation and plaque accumulation were reduced. It was shown that Parodontax® was effective in reducing the enzymatic activity of inflammation.

Medicine and science in sports and exercise. 2010;(4):798-804
Abstract
PURPOSE The aim of this study was to investigate the influence of mouth rinsing a CHO-electrolyte (CHO-E) solution on 1-h running performance. A second study determined whether mouth rinsing a CHO-E solution altered the blood glucose and plasma insulin concentrations at rest. METHODS After a 13-h fast, 10 endurance-trained male runners completed two 1-h performance runs on an automated treadmill while mouth rinsing 25 mL of either a 6.4% CHO-E (C) or placebo (P) solution immediately before and at 15-min intervals during the 1-h run. An additional 10 healthy active males followed the same mouth rinsing procedure during a 1-h resting period. Finger prick blood samples were obtained for the determination of blood glucose and plasma insulin concentrations. RESULTS Runners covered 211 m (90% confidence intervals = 42-380 m, P = 0.048) further during the C trial (14,298 ± 685 m, mean ± SD) in comparison with the P trial (14,086 ± 732 m). There was no change in blood glucose concentrations during the 1-h run (P: pre = 4.3 ± 0.2 mmol·L(-1), post = 4.3 ± 0.3 mmol·L(-1); C: pre = 4.3 ± 0.4 mmol·L(-1), post = 4.3 ± 0.3 mmol·L(-1)). At rest, there was no change in blood glucose (P: 4.3 ± 0.1 mmol·L(-1), C: 4.3 ± 0.2 mmol·L(-1)) or plasma insulin (P: 6.2 ± 1.1 mU·L(-1), CHO: 5.9 ± 1.0 1.1 mU·L(-1)) concentrations (P > 0.10). CONCLUSIONS Mouth rinsing a 6.4% CHO-E solution was associated with increased distance covered during a 1-h performance run in comparison to mouth rinsing a placebo solution. Mouth rinsing a CHO-E was not associated with changes in blood glucose concentration during exercise or at rest.

Abstract
Previous studies demonstrated that a Ca pre-treatment greatly increases salivary F from a subsequent NaF rinse. This study examines if these increases are found in plaque and plaque fluid F. Thirteen individuals accumulated plaque before rinsing with: (1) 12 mmol/L NaF (228 microg/g F), (2) 150 mmol/L Ca rinse, or (3) the Ca rinse followed by the F rinse. One hr later, plaque samples were collected, the plaque fluid was recovered, and the plaque residues were extracted 5 times with pH 6.8 or pH 4.8 buffers, and then by acid. The F in each extract after the Ca rinse/F rinse greatly exceeded the corresponding F from the NaF rinse. Consequently, the Ca rinse/F rinse increased the total plaque F and the plaque fluid F by 12x and 5x, compared with the NaF rinse alone. These and the previous salivary results suggest that a Ca pre-treatment may increase the cariostatic effects of topical F agents.
