INTRODUCTION: Effective self-care is difficult for people with orthodontic appliances because of the inherent design of brackets and archwires. It is not uncommon to have increases in plaque and gingivitis after placement of fixed appliances. The purpose of this study was to evaluate the effect of using a dental water jet (DWJ) with a specialized tip (orthodontic) on plaque and bleeding in adolescent orthodontic patients with fixed appliances. METHODS: One hundred six subjects were enrolled in this single blind, parallel clinical study. They were randomly assigned to 1 of 3 treatment groups: group 1, once daily irrigation with a DWJ and orthodontic jet tip plus a manual toothbrush; group 2, once daily flossing (FL) plus a manual toothbrush; group 3, manual toothbrush (MT) only. Plaque index (PI) and bleeding index (BI) scores were recorded at baseline, and at 2 and 4 weeks. RESULTS: All groups showed statistically significant reductions in PI (whole mouth and interproximal) at 2 and 4 weeks (P <.001). In group 1, the DWJ was statistically more effective at reducing whole-mouth and interproximal plaque than the methods in the other groups (P >.001) at both 2 and 4 weeks, whereas the FL protocol in group 2 was significantly more effective than the MT protocol in group 3 at 4 weeks (P =.025) for whole-mouth plaque and at 2 and 4 weeks (P = .011 and P = .028, respectively) for interproximal plaque. All groups showed statistically significant reductions in BI (whole mouth and interproximal) at 2 and 4 weeks (P <.001). The DWJ in group 1 was statistically more effective at reducing whole-mouth bleeding than the protocols of the other groups at 2 and 4 weeks (P <.001), and the FL was statistically more effective than the MT at both times (P <.001). Both the DWJ and the FL were significantly more effective than the MT at 2 weeks (P <.001 and P <.016, respectively) for interproximal bleeding, but there were no differences between the groups at 4 weeks. CONCLUSIONS: A DWJ with a specialized orthodontic jet tip is effective for adolescents in fixed orthodontic appliances; it demonstrated beneficial results for the reduction of plaque and bleeding.

Factors associated with self-reported halitosis (SRH) and perceived taste disturbance (PTD) in elderly.   Arch Gerontol Geriatr, 46(3): 307-316.

The aim of this study was to estimate the prevalence of self-reported halitosis (SRH) and perceived taste disturbance (PTD) and analyze their association with age, gender, subjective oral dryness, burning mouth, tongue coating, number of teeth remaining, and type of dentures and wear duration in healthy elderly. Subjects who neither reported systemic disorders nor medication use were included in the study. The participants of this study were 254 healthy subjects, 116 males (mean age: 63.2+/-7.2 ...

Molecular identification of bacteria on the tongue dorsum of subjects with and without halitosis.   Oral Dis, 14(3): 251-8.

AIM: Compare the microbial profiles on the tongue dorsum in patients with halitosis and control subjects in a UK population using culture-independent techniques. MATERIALS AND METHODS: Halitosis patients were screened according to our recently developed recruitment protocol. Scrapings from the tongue dorsum were obtained for 12 control subjects and 20 halitosis patients. Bacteria were identified by PCR amplification, cloning and sequencing of 16S rRNA genes. RESULTS: The predominant species ... [Abstract] [Full-text]

The levels of volatile sulfur compounds in mouth air from patients with chronic periodontitis.   J Periodontal Res, 43(2): 186-93.

BACKGROUND AND OBJECTIVE: Volatile sulfur compounds may be the main source of oral malodor. The aim of this study was to clarify the relationship between periodontal parameters and volatile sulfur compounds and to evaluate the improvement of several halitosis-related outcomes by tongue scraping, nonsurgical periodontal treatment (including oral hygiene instruction) and oral hygiene instruction/chlorhexidine + cetyl pyridinium gargling. MATERIAL AND METHODS: Seventy-two chronic periodontitis ... [Abstract] [Full-text]

Objective: To assess the occurrence of oral pathological changes and symptoms in patients affected by gastro-oesophageal reflux disease (GERD). Patients and methods: 200 patients with GERD and 100 matched healthy controls were studied. Thorough visual examination of the dental and oral mucosal tissues was performed and medical history relevant to oral symptoms was collected. The primary outcome was defined as a statistically significant difference, between the study group and controls, in the ... [Abstract] [Full-text]

Self-reported halitosis and gastro-esophageal reflux disease in the general population.   J Gen Intern Med, 23(3): 260-6.

BACKGROUND: Patients with halitosis contact primary care practitioners, dentists, and gastroenterologists alike. OBJECTIVES: It is unclear whether gastroesophageal reflux disease (GERD) is a risk factor for halitosis. DESIGN AND PATIENTS/PARTICIPANTS: We studied this possible relationship in the general population using the cross-sectional Study of Health in Pomerania (SHIP). Employing structured interviews, self-reported halitosis was assessed among 417 edentulous (toothless) subjects aged 40 ... [Abstract] [Full-text]

STUDY DESIGN: In this double-blind selective clinical trial, 80 participants (40 women, 40 men) who had undergone third molar surgery were divided into 5 groups, and different mouth rinses were given to each: 0.2% chlorhexidine gluconate (Chx), 0.12% chlorhexidine gluconate with 0.15% benzydamine hydrochloride (Chx+Bzd), 7.5% ...

INTRODUCTION: Although powered toothbrushes have been recommended for gingivitis prevention in orthodontic patients, a relevant meta-analysis has been lacking. The aim of this meta-analysis was to compare the effectiveness of powered and manual toothbrushes in reducing gingival inflammation in patients having fixed orthodontic appliance therapy. METHODS: Citations of potentially relevant trials published in journals, dissertations, and conference proceedings were located by searching the ... [Abstract] [Full-text]
