BACKGROUND Orthodontic therapy has oral ecological changes causing increased numbers of mutans streptococci in saliva and plaque. The purpose of this study was to estimate counts and colonization pattern of Streptococcus mutans after application of fixed orthodontic appliances. MATERIALS AND METHODS Plaque samples of randomly selected sixty patients were collected before placement of orthodon...

Trauma to oral soft tissues in comatose patients may be more widespread than reported, as no extensive study of this problem has been conducted. Various appliances for the prevention of self-inflicted injuries to oral tissues particularly in children and the physically and mentally challenged have been documented, but there is little information on their use in adult comatose patients. Because ...

Abstract During the orthodontic process, increased microbial colonization and dental plaque formation on appliances auxiliaries are major complications, causing oral infectious diseases, such as caries periodontal diseases. To reduce accumulation, antimicrobial materials increasingly being investigated applied to by various methods. Through development of nanotechnology, nanoparticles (NPs) hav...

Aim: The aim of this study was to determine the dependency of secretory immunoglobulin A (S-IgA) on the risk markers of the oral environment, such as the quality of the saliva, the dental biofilm, the oral Candida and Lactobacillus spp. in children. Methods: The study was conducted on a total of 116 children who were divided into four groups, which were: diabetes, asthma, orthodontic appliances...

Upper removable appliances (URA), as well as full dentures, are known to be the cause of various complaints related to oral handling of food and beverages, phonation and vocalization, in addition to general discomfort. To test the hypothesis that taste and flavour perception might also be affected by URA, 22 young orthodontic patients (10 males and 12 females aged 11.5 +/- 1.7 years; experiment...

Obstructive sleep apnoea is a chronic condition characterized by repetitive episodes of upper airway collapse during sleep, leading to sleep fragmentation. The management of sleep apnoea consists of general and specific measures. General measures should include weight loss in overweight patients; avoidance of alcohol during the evening hours; avoidance of any hypnotic drug. Specific measures ma...

OBJECTIVE To explore predictors of adherence in adult orthodontic patients as reported by orthodontists in the UK. MATERIALS AND METHODS Twenty-three orthodontists (47% female and 53% male) from the UK with approximately 15 years of experience each (M  =  14.7; SD  =  1.73) completed a questionnaire regarding the importance they give to a number of factors signaled in the literature as adequa...

INTRODUCTION Plaque control is the major consensus during orthodontic treatment to prevent the occurrence of cavities and periodontal inflammation. The mechanic resource of greater effectiveness and frequent use in this control is the oral hygiene. The tooth brushing techniques most used in orthodontic patients are: Ramfjord's method, Modified Stillman technique and Bass method. OBJECTIVE Sin...

Oral appliances have been a popular treatment option for subjects with obstructive sleep apnea. However, little information is available on how brain activation induced by respiratory challenge is modulated by mandibular advancement with these appliances. We hypothesized that the brain activation caused by respiratory stress may be alleviated by mandibular advancement. Respiratory stress was in...
