INTRODUCTION: This is a case report of a 39-year-old patient with a 14-year history of clinically refractory cluster headache (CH), also presenting obstructive sleep apnea (OSA) and complaining of tooth-grinding during sleep. DISCUSSION: Treatment of OSA with an intra-oral device allowed an immediate reduction in frequency and intensity of CH events. Furthermore, CH attacks did not occur during the 12-month follow-up period.

An ambulatory bruxism recording system with sleep-stage analyzing function.   J Prosthodont Res, 53(3): 150-4.

PURPOSE: The aim of this study was to develop an ambulatory bruxism recording system capable of sleep-stage analysis. METHODS: A portable EMG system was used to record masseter muscle activity. An EMG sensor was attached onto the masseter muscle belly at either side. EMG data were stored on a notebook type personal computer. A sound level meter was used to assess the sound level of bruxism. Sound level (dB) readings were taken every second and recorded on the same computer. A prototype of sleep ... [Abstract] [Full-text]

Bruxism affects stress responses in stressed rats.   Clin Oral Investig.

It has been proposed that suppression of stress-related emotional responses leads to the simultaneous activation of both sympathetic and parasympathetic divisions of the autonomic nervous system (ANS) and that the expression of these emotional states has a protective effect against ulcerogenesis. In the present study, we investigated whether stress-induced bruxism activity (SBA) has a physiological effect of on the stress-induced changes of the stomach, thymus, and spleen as well as blood ...

Retrospective analysis of porcelain failures of metal ceramic crowns and fixed partial dentures supported by 729 implants in 152 patients: patient-specific and implant-specific predictors of ceramic failure.   J Prosthet Dent, 101(6): 388-94.

STATEMENT OF PROBLEM: Porcelain fracture associated with an implant-supported, metal ceramic crown or fixed partial denture occurs at a higher rate than in tooth-supported restorations, according to the literature. Implant-specific and patient-specific causes of ceramic failure have not been fully evaluated. PURPOSE: The purpose of this retrospective study was to evaluate the potential statistical predictors for porcelain fracture of implant-supported, metal ceramic restorations. MATERIAL AND ...

Sleep in post-menopausal women: Differences between early and late post-menopause.   Eur J Obstet Gynecol Reprod Biol.

OBJECTIVE: The aim of this study was to evaluate the differences in sleep between women of early and late post-menopause. STUDY DESIGN: Thirty post-menopausal women who came to the climacteric service of their own volition were selected. Fourteen were in early post-menopause (less than 5 years after menopause), and sixteen were in late post-menopause (more than 5 years since menopause). None of the women were suffering from any other clinical diseases. Participants had no previous history of ... [Abstract] [Full-text]

Bilateral cyclic cheek lesions related to premenstrual syndrome: a multifactorial pathogenesis?   Arch Gynecol Obstet, 279(6): 927-9.

INTRODUCTION: Cheek biting is a chronic, usually innocuous, self-inflicted injury that often occurs as a parafunctional habit. CASE REPORT: We report an unusual case of bilateral cyclic cheek lesions in a 34-year-old woman characterized by hyperkeratinization near the biting edges of the teeth and hematic lesions accompanied by a cheek swelling sensation, without pain and burning. The lesions coincided with a premenstrual syndrome, characterized by fluid retention-related symptoms, such as leg ... [Abstract] [Full-text]

Comorbidity of Enuresis in Children With Attention-Deficit/Hyperactivity Disorder.   J Atten Disord.

Objective: To compare parental psychopathology and psychiatric disorders in ADHD children with and those without enuresis. Method: The participants of the clinical sample interviewed according to DSM-IV diagnostic criteria were 35 children with ADHD and enuresis, 153 ADHD children without enuresis, 115 fathers, and 172 mothers. Results: Only ODD comorbidity was the predictor of enuresis. Conduct disorder, tic disorder, major depressive disorder, separation anxiety disorder, bruxism, generalized ... [Abstract] [Full-text]

Sleep duration, wake/sleep symptoms, and academic performance in Hong Kong Secondary School Children.   Sleep Breath.

BACKGROUND: Sleep deprivation is common among teenagers. The aim of this study was to investigate the relationship between sleep duration, wake/sleep symptoms, and academic performance among Hong Kong students. MATERIALS AND METHODS: The sleep habit questionnaires were distributed to all Year 11 students at an international school that catered to different ethnic groups in Hong Kong. Analysis of various parameters of academic performance and sleep habits and their relationships were undertaken. ... [Abstract] [Full-text]

The Prevalence of Cervical Tooth Wear in Patients with Bruxism and Other Causes of Wear.   J Prosthodont.

Purpose: The aim of this study was to investigate the prevalence of cervical wear lesions in three groups of patients: bruxists, combined tooth wear, and controls. The hypothesis was that those subjects presenting with bruxism were more likely to develop cervical wear lesions. Materials and Methods: Of 119 subjects, 31 were bruxists with a mean age 48.7 years [standard deviation (SD): 11.6]; 22 had combined wear, aged 43.5 years (14.2); and 66 controls aged 44.9 years (17.0). The clinical ... [Abstract] [Full-text]
