Efficacy of new oral rinse containing sodium hyaluronate in xerostomia: A randomized crossover study.

OBJECTIVES: To evaluate the efficacy of a new oral rinse containing sodium hyaluronate and other functional ingredients in reducing xerostomia-associated symptoms. MATERIALS AND METHODS: In this 8-week, double-blind crossover study, xerostomia subjects used all three of GUM®HYDRAL™ Oral Rinse, placebo rinse, and Biotene® Oral Rinse as active control. Visual Analog Scale, a dry mouth questionnaire, Oral Health Impact Profile-14, unstimulated saliva flow rate (USFR), and Revised Oral Assessment Guide (ROAG) were assessed before and after 2 weeks of treatments. RESULTS: Thirty-seven patients completed all three treatment modalities. Subjective measurements were significantly decreased by test product and active control; however, no significant difference was observed between the treatments. Test product and active control demonstrated a significant increase in USFR over 0.2 ml/min, a normal threshold of hyposalivation. Both test product and active control improved a total score of ROAG, whereas the effectiveness of the test product was significantly better than that of other two treatments. CONCLUSIONS: The new oral rinse may be beneficial to improve the quality of life of xerostomia patients as dry mouth symptoms were reduced for both subjective and objective measurements. Test oral rinse was found to be more effective than placebo or active control for some of the objective measurements.

Bisphosphonate-related osteonecrosis of the jaw: Current clinical significance and treatment strategy review.

PURPOSE: This review paper is intended to provide updated information about the significance of bisphosphonate-related osteonecrosis of the jaw (BRONJ) related to dental departments and also to provide treatment information. However, it does not review anti-resorptive related osteonecrosis of the jaw (ARONJ). METHODS: PubMED was searched for published articles on BRONJ that have particular relevance to clinical aspects in orthodontics, endodontics, periodontics, prosthodontics, oral and maxillofacial surgery, implants and treatment planning. In vitro and animal studies were excluded. RESULTS: Bisphosphonate therapy has a significant level of importance within all dental departments, and the treatments for BRONJ are diverse without any documented superiority of one over another. CLINICAL SIGNIFICANCE: Each dental specialty must be aware of the risk of BRONJ in their patients, especially elderly ones with history of bone-related therapy or tumor. No definite consensus is made for some departments due to lack of evidence and rare cases.

Phosphate buffer-stabilized 0.1% chlorine dioxide oral rinse for managing medication-related osteonecrosis of the jaw.

PURPOSE: This is a review of the literature on nonsurgical treatment of non-healing medication related osteonecrosis of the jaw (MRONJ) utilizing a phosphate buffer-stabilized 0.1% chlorine dioxide mouthrinse. METHODS: A literature search in PubMed revealed only six case reports. MRONJ lesion site description, patient's medication history, the healing time, and the MRONJ treatment protocol followed by those authors were recorded. Additional literature review of the scientific mechanism, risks and benefits, safety and efficacy of the phosphate buffer-stabilized 0.1% chlorine dioxide mouthrinse was also performed and discussed. RESULTS: Many of the authors of the published case reports utilized 0.12% chlorhexidine as the initial mouthrinse, but the lesions did not decrease in size. After switching to a phosphate buffer-stabilized 0.1% chlorine dioxide mouthrinse for a duration ranging from 1-12 months, there was complete healing of the MRONJ lesions in all of the cases. The phosphate buffer-stabilized 0.1% chlorine dioxide mouthrinse can be helpful in the management of active MRONJ lesions as well as the prevention of recurrent MRONJ lesions in the susceptible patient population. CLINICAL SIGNIFICANCE: This literature review supports the use of phosphate buffer-stabilized 0.1% chlorine dioxide mouthrinse in the management of MRONJ lesions either as a first line of therapy or after 0.12% chlorhexidine had not been effective.

Influence of full mouth rehabilitation on oral health-related quality of life among disabled children.

The efficacy of full mouth rehabilitation (FMR) on oral health-related quality of life of physically disabled children was assessed. This prospective study was performed at Dental Department of Sultan Bin Abdulaziz Humanitarian City, Riyadh, and King Abdulaziz University Hospital, Jeddah, Saudi Arabia, during May 2012 to September 2014. A total of 186 physically disabled children aged 11-14 years were assigned to a test group (n = 97) or a control group (n = 89). FMR was applied for test group children at baseline and 3 months' visits, whereas those in the control group did not receive FMR. Both group children received dental kits and oral hygiene instructions. Children were asked to complete the Child Perceptions Questionnaire, whereas Parental-Caregiver Perceptions Questionnaire and Family Distress Domain questionnaire were completed by the parents/caregivers at baseline and 6 months' visits. Children in both groups showed positive trends in oral symptoms at 6 months compared with those at baseline. However, when they were compared to control, significant improvement in oral symptoms was observed in the test group at 6 months' visit (p < .05). Also when they were compared to control, significant improvements were observed in the functional limitation, emotional, and social well-being subscales of the Child Perceptions Questionnaire and on the Parental-Caregiver Perceptions Questionnaire scales at the end of the study (p < .05). Compared to the parents/caregivers of the control children, the parents/caregivers of the test-group children reported insignificant but positive trends in Family Distress Domain at the end of the study (p < .05). FMR in children reduced oral-related problems subsequently to a better oral health-related quality of life.

Comparison of 3 intranasal mists for anesthetizing maxillary teeth in adults: A randomized, double-masked, multicenter phase 3 clinical trial.

BACKGROUND: This double-masked, parallel-design, clinical trial assessed whether a combination nasal spray (K305; 3% tetracaine hydrochloride and 0.05% oxymetazoline hydrochloride) compared with a tetracaine-only spray and a placebo spray would be safer and superior in producing local anesthesia sufficient to complete a direct restorative procedure in maxillary nonmolar teeth. METHODS: The authors randomized eligible patients to receive K305 spray (n = 44), tetracaine hydrochloride spray (n = 44), or a placebo solution (n = 22). The authors compared the incidence of the primary efficacy end point-completion of the procedure without rescue local anesthetic-by means of a 1-tailed Fisher exact test. RESULTS: The end point incidence was 84.1% (95% confidence interval [CI], 69.9-93.4) with K305, 27.3% (95% CI, 15.0-42.8) with tetracaine only, and 27.3% (95% CI, 10.7-50.2) with placebo (P < .001 for K305 versus tetracaine only and versus placebo). Combination spray was associated with statistically significant but transient increases in blood pressure. The most frequent adverse events were rhinorrhea and nasal congestion, which resolved within 2 hours after treatment and occurred more often in the K305 group and tetracaine-only group. CONCLUSIONS: In this study population, the K305 combination nasal spray was safe and more effective in attaining pulpal anesthesia of maxillary teeth from premolar to premolar compared with tetracaine-only and placebo sprays. PRACTICAL IMPLICATIONS: The combination nasal spray might represent a valuable alternative to injected local anesthetic for patients undergoing invasive maxillary dental procedures.

Mouthwashes: Rationale for use.

PURPOSE: To update the rationale for the use of mouthwashes and summarize data on the incorporation of an antibacterial, cetylpyridinium chloride (CPC), into a new mouthwash formulation. Data from various published articles are reviewed which demonstrate the value of mouthwashes. Also this Special Issue provides research supporting the efficacy of 0.075% cetylpyridinium chloride in a new, alcohol-free mouthwash formulation (Colgate Total). RESULTS: Benefits of mouthwashes include improving the reduction of plaque biofilm as an adjunct to oral hygiene, killing bacteria in areas difficult to reach by normal oral hygiene, killing bacteria on non-tooth oral surfaces, reaching bacteria subgingivally by placement in an irrigator, and supporting a positive effect on oral health by reducing bacteremia from oral micro-organisms. The benefits of including CPC in this new formulation are demonstrated by in vitro and clinical studies which demonstrate the efficacy of this formulation of CPC on biofilm as well as an effect on the reduction of plaque and gingivitis in three clinical studies.

Can Chemical Mouthwash Agents Achieve Plaque/Gingivitis Control?

Also note that structured abstracts are not allowed per journal style: What is the effect of a mouthwash containing various active chemical ingredients on plaque control and managing gingivitis in adults based on evidence gathered from existing systematic reviews? The summarized evidence suggests that mouthwashes containing chlorhexidine(CHX) and essential oils (EO) had a large effect supported by a strong body of evidence. Also there was strong evidence for a moderate effect of cetylpyridinium chloride(CPC). Evidence suggests that a CHX mouthwash is the first choice, the most reliable alternative is EO. No difference between CHX and EO with respect to gingivitis was observed.

Management of Gingival Overgrowth in a Cardiac Transplant Patient Using Laser-Assisted Gingivectomy/Gingivoplasty.

Drug-induced gingival overgrowth (DIGO) is an oral clinical manifestation associated with certain medications such as immunosuppressants that are administered to organ transplant patients to prevent graft rejection. In patients with cardiac transplants, management of DIGO is critical. In such patients, plaque biofilm accumulation at the gingival interface might be detrimental as it may lead to transient bacteremia as well as systemic inflammation resulting in thromboembolic events. This case report describes the management of DIGO in a cardiac transplant recipient by change of immunosuppressant medication, non-surgical periodontal therapy and laser-assisted gingivectomy.

Evaluation of adjunctive systemic doxycycline with non-surgical periodontal therapy within type 2 diabetic patients.

OBJECTIVES: To evaluate the effects of systemic doxycycline on clinical and microbiological parameters of diabetic subjects with chronic periodontitis. METHODS: This 9-month multi-center, randomized, parallel, single-blinded study was conducted from different hospitals in Riyadh, Saudi Arabia between April 2010 and December 2010. A total of 76 diabetic subjects with chronic periodontitis were randomized into 2 groups: control group (CG) received only scaling and root planing (SRP), and the treatment group (TG) receiving systemic doxycycline during the reevaluation visit 45 days after the completion of SRP. Probing pocket depth, clinical attachment level, gingival index, plaque index, and bleeding on probing were collected at baseline, 45 days after SRP, and one, 3, and 6 months  after the use of systemic doxycycline. Microbiological analysis comprised the detection of Tannerella forsythia (Tf), Aggregatibacter actinomycetemcomitans (Aa), Porphyromonas gingivalis (Pg), and Prevotella intermedia (Pi) by polymerase chain reaction method. RESULTS: Sixty-eight (33 CG and 35 TG) subjects completed the study. Greater reduction in the population of Tf, Pg, and Pi were observed in TG compared with CG in the first month after the administration of systemic doxycycline. The TG showed a significant improvement in gingival index scores compared with the CG (p<0.05) by the end of the first and 6 months after the administration of doxycycline. CONCLUSION: Adjunct systemic doxycycline can be associated with a reduction of Tf, Pg, and Pi in the first month after the administration of doxycycline with an improvement in the GI. 

A pilot test of motivational oral health promotion with alcohol-dependent inpatients.

OBJECTIVE: Motivational interviewing (MI) is an effective intervention for improving health behavior in a number of domains, and evidence suggests that it may be useful for promoting oral health. The current pilot study was designed to provide initial evidence that, compared with a didactic control intervention, a brief MI-based intervention (BMI) delivered by dental practitioners can yield greater improvements in oral hygiene, health-care utilization, and health outcomes in a population at heightened risk for oral disease. METHOD: Either the control intervention or BMI, delivered by a dentist or a dental hygienist, was randomly assigned to 60 individuals in inpatient treatment for alcohol-use disorders. Data were obtained by self-report and by examination at baseline and 4-, 12-, and 24-week follow-up assessments. RESULTS: BMI participants reported significantly more frequent toothbrushing during follow-up than control participants. No other significant effects were found. CONCLUSION: These findings indicate that a brief intervention using MI methods can be delivered by dental professionals and has potential utility for promoting improved oral hygiene. Additional research to investigate and further develop MI's potential for promoting oral health appears warranted.

The prevalence of oral Candida infections in periodontitis patients with type 2 diabetes mellitus.

OBJECTIVES: The purpose of this study was to determine the prevalence of Candida spp. in periodontitis patients with type 2 diabetes mellitus. METHODS: This cross-sectional study included 42 diabetic patients with periodontitis (aged 21-70 years; 18 males and 24 females). Clinical measurements included probing pocket depth (PPD), clinical attachment level (CAL) and hemoglobin A1c (HbA1c) levels. Sub-gingival samples were collected from the mesio-buccal aspect of 3 teeth for fungal analysis. Candida species, including Candida albicans, Candida dubliniensis, Candida tropicalis and Candida glabrata, were identified using Gram staining, the germ tube test, CHROMagar, Staib agar and API 20C AUX. RESULTS: The overall prevalence of Candida in diabetic patients with periodontitis observed in our study was 52%. The most common spp. of Candida identified were C. albicans (38%), followed by C. dubliniensis (9.5%), C. tropicalis (4.7%) and C. glabrata (4.7%). Compared to females, male patients were characterized by increased levels of Candida infections. Our results also indicate that individuals over the age of 40 had increased levels of Candida infections compared to patients younger than 40. Candida infections were higher among subjects with elevated blood sugar levels (HbA1c>9) compared to individuals with well-controlled blood sugar levels (HbA1c<6). Patients with PPDs≥5 had an increased risk of Candida infection compared to patients with PPDs between 3 and 4. CONCLUSION: This study indicates that the frequency of C. albicans is higher than the frequencies of C. dubliniensis, C. tropicalis and C. glabrata in diabetic patients with periodontitis. Candida infections were observed at increased frequencies among subjects with high blood sugar levels and PPDs≥5.

An evaluation of 10 percent and 20 percent benzocaine gels in patients with acute toothaches: efficacy, tolerability and compliance with label dose administration directions.

BACKGROUND: The authors evaluated the efficacy and tolerability of 10 percent and 20 percent benzocaine gels compared with those of a vehicle (placebo) gel for the temporary relief of toothache pain. They also assessed the compliance with the label dose administration directions on the part of participants with toothache pain. METHODS: Under double-masked conditions, 576 participants self-applied study gel to an open tooth cavity and surrounding oral tissues. Participants evaluated their pain intensity and pain relief for 120 minutes. The authors determined the amount of gel the participants applied. RESULTS: The responders' rates (the primary efficacy parameter), defined as the percentage of participants who had an improvement in pain intensity as exhibited by a pain score reduction of at least one unit on the dental pain scale from baseline for two consecutive assessments any time between the five- and 20-minute points, were 87.3 percent, 80.7 percent and 70.4 percent, respectively, for 20 percent benzocaine gel, 10 percent benzocaine gel and vehicle gel. Both benzocaine gels were significantly (P ≤ .05) better than vehicle gel; the 20 percent benzocaine gel also was significantly (P ≤ .05) better than the 10 percent benzocaine gel. The mean amount of gel applied was 235.6 milligrams, with 88.2 percent of participants applying 400 mg or less. CONCLUSIONS: Both 10 percent and 20 percent benzocaine gels were more efficacious than the vehicle gel, and the 20 percent benzocaine gel was more efficacious than the 10 percent benzocaine gel. All treatments were well tolerated by participants. Practical Implications. Patients can use 10 percent and 20 percent benzocaine gels to temporarily treat toothache pain safely.

The effect of an 810-nm diode laser on postoperative pain and tissue response after modified Widman flap surgery: a pilot study in humans.

BACKGROUND: The purpose of this single-masked pilot clinical study is to compare the tissue response and postoperative pain after the use of a diode laser (810 nm) (DL) as an adjunct to modified Widman flap (MWF) surgery to that of MWF alone. METHODS: Thirteen patients with generalized severe chronic periodontitis completed the study. Control sites were randomly selected to receive an MWF and the contralateral test sites an MWF in conjunction with a DL. The study tooth/site was treated plus any additional teeth in the quadrant in which the site was located, if needed. Randomization was done using a coin flip. The DL was used to de-epithelialize the inner part of the periodontal flap and photo-biostimulate the surgical area. Pain scale assessment (PS), pain medication consumption (PM), tissue edema (TE), and tissue color (TC) were evaluated 1 week after surgery. RESULTS: Statistically significant differences were seen for TE (P = 0.041), PM (P <0.001), and PS (P <0.001) favoring test sites. TC did not show a statistically significant difference (P = 0.9766). Patients rated the first surgical treatment (test or control; random assignment to first treatment) performed as more painful than the second (P <0.002). CONCLUSION: The use of an 810-nm diode laser provided additional benefits to MWF surgery in terms of less edema and postoperative pain.
