The Mandibular Function Impairment Questionnaire (MFIQ) was developed for clinical assessment of functional impairment in patients with temporomandibular disorder (TMD). It allows patients to rank difficulty performing 17 jaw-related functions as low, moderate or severe. Our study was designed to determine whether the MFIQ is also helpful in differentiating TMD from other causes of orofacial pain in a clinical setting.

To compare trends in teaching and placement of composite resin versus amalgam in posterior restorations in Canadian dental schools with those in the United States.

A growing body of literature highlights the negative impact of the COVID-19 pandemic on the mental health of health care professionals. This paper explores the effects of gender and work/life factors on dentists' mental health before and during the pandemic.

Osteomyelitis (OM) of the jaw is a rare medical condition. In this review, we provide a descriptive analysis of the experience with this condition at a single tertiary health care centre in Canada over 10 years.

Infective endocarditis (IE) remains one of the most serious diseases with a high morbidity and mortality rate. Although the condition is more common in the medical field in a hospital setting, dentists must have a thorough understanding of the overall pathogenesis, epidemiology, risk factors and signs and symptoms that may be present in their patient population. In 2021, the American Heart Association (AHA) updated its guidelines on IE, emphasizing the specific criteria that put a patient at risk of acquiring IE, specific dental procedures that can increase the risk of IE by inducing bacteremia and an antibiotic prophylaxis regimen to act as a preventive measure if needed. This literature review gives the dental practitioner a general overview of the AHA guidelines as well as information on prevention in their at-risk patients and the need to emphasize a well-structured, consistent daily oral hygiene routine.

Although routine dental care is essential for both oral and overall health, in Canada, access to such care is uneven. Those with low or medium income and no workplace dental coverage often face financial barriers in accessing dental care. However, the factors that affect access - income, employer-provided health benefits and public dental care subsidy programs - have changed over the decades. This study examines the net impact of these factors on long-term trends in dental care access among different groups in Canada over the past 5 decades.

Patients with recurrent or persistent dentoalveolar pain usually believe that endodontic treatment or extracting a tooth will alleviate it, and most cannot conceive that the pain might not be tooth related. Understanding that dental procedures of any kind will be ineffective when a tooth-related pathology is ruled out and that a nonodontogenic etiology best explains the "toothache" pain goes against their beliefs. In this article, we present an overview of basic concepts to help manage such cases by briefly outlining possible causes of nonodontogenic pain as well as diagnostic pitfalls that may lead to questionable treatments. The decision to provide dental treatment is justified only when definitive peripheral mechanisms driving the pain are uncovered and the multitude of factors that might contribute to the various presentations of persistent dental pain have been considered. Otherwise, patients might be managed with treatments that are not the norm for those with unremitting tooth pain in general dental practice. We also make suggestions for clinicians to assure that patients with recurrent or persistent dental pain receive a thorough work-up that considers odontogenic and nonodontogenic sources to arrive at the correct diagnosis before treatment, taking psychosocial factors into account when devising the treatment plan.

To investigate the impact of a COVID-19 mandated lockdown on the type and frequency of dental services accessed at an undergraduate dental clinic in southwestern Ontario.

Professors Elham Emami and Samira Rahimi organized and co-led an international interdisciplinary workshop in June 2023 at McGill University, built upon an intersectoral approach addressing equity, diversity and inclusion within the field of AI.

The onset of the COVID-19 pandemic and government restrictions affecting dental health care professionals had an impact on pediatric dental emergency trends. The purpose of this study was to describe the effect of the COVID-19 pandemic on the characteristics, outcomes and management of pediatric dental emergencies in a single tertiary care hospital.

Human papillomavirus (HPV), as the most common form of sexually transmitted infection, has been implicated in almost one-third of oropharyngeal cancers. One way to prevent HPV infections is through vaccination. This study aimed to investigate whether dentists in British Columbia (BC) were willing to discuss, refer and administer the vaccine in a dental practice setting.

The literature indicates that youth with intellectual/developmental disabilities (IDD), such as Down syndrome or autism, have poor oral health. A number of factors influence their oral health, including the use of medically required dental treatments.

Studies show concerning rates of occupational violence against oral health care workers, but few studies of this nature have been conducted on dental students in university clinics.

The COVID-19 pandemic has resulted in amended regulations and guidelines governing the practice of dentistry and dental hygiene to ensure the protection of both patients and clinicians from transmission of the SARS-CoV-2 virus. These guidelines include changes in personal protective equipment and, under some guidelines, the institution of a fallow period after any aerosol-generating procedure (AGP). This study aimed to investigate the effect of both ventilation and 4-handed dentistry in clinical practice with patients undergoing supportive periodontal therapy (SPT) by air polishing, ultrasonic and hand instrumentation in a closed operatory. We studied 34 patients during SPT using either 2- or 4-handed dentistry in an operatory with either 0 or 20 additional air changes/h (ACH). Under clinical conditions, 20 additional ACH are adequate to eliminate aerosols produced during an SPT and before the cessation of the AGP. The presence of an assistant had no significant effect on the time needed for aerosol particles to return to baseline values following the AGP. This study supports the efficacy of 20 additional ACH during the process of AGP, but does not support the need for an extended fallow period or 4-handed dentistry to provide additional high-volume evacuation throughout the procedure.

Community water fluoridation is one component of a multifactorial approach to preventing dental caries. Yet, fluoridation monitoring in Canada has historically been fragmented, and recent national estimates give little indication of trends at the provincial or municipal levels. We aimed to quantify fluoridation exposure trends in Alberta from 1950 to 2018 at both the population and municipal levels. Insights have implications for dental public health surveillance.

Hypertension is a serious chronic illness that affects more than a third of the world's population. The high prevalence of hypertension coupled with its lack of initial clinical symptoms can make managing a hypertensive patient in a dental setting difficult. The dentist's role in managing hypertensive patients encompasses more than simple treatment modifications. Because of the frequency of dental checkups, dentists play an integral role in the detection of elevated blood pressure and appropriate subsequent referral. As such, it is imperative that dentists are aware of risk factors associated with hypertension to council patients early. In addition, antihypertensive medications pose a risk in dental treatment. Such drugs may produce various oral presentations and interact negatively with drugs commonly prescribed by the dentist. It is critical to recognize these changes and avoid possible interactions. Furthermore, dental treatment can often induce fear and anxiety resulting in an increase in blood pressure; this can further complicate management of patients with pre-existing hypertension. As research and recommendations are constantly changing, dentists must stay informed on how to appropriately administer care. This article is intended to provide the dental team with clear guidelines on the overall management of a hypertensive patient in a dental clinic.

On September 7, 2022, the University of Montpellier in France hosted a meeting with digital oral health technology developers, Chief Dental Officers, policy makers, the World Health Organization, the International Telecommunication Union, and academia on digital oral health technologies.

The aims of this study were to determine demographic profiles, tumour characteristics and treatment factors related to oral cavity and oropharyngeal cancer (OCC and OPC) and comparatively analyze these cancers in the adult population of Alberta, Canada, over 12 years.

Portfolios, collected evidence of students' learning and achievement, have been widely used in health profession education for learning and assessment purposes. However, little has been documented on their use to foster self-reflection in preclinical dental education. This exploratory study assessed students' views of portfolio assignments to foster self-reflection in preclinical operative dentistry courses.

The rate of general anesthesia (GA) use for pediatric dental treatment in Saskatchewan is among the highest in Canada. Although the prevalence of and risk factors for early childhood caries (ECC) has been reviewed nationally, few studies have focused on Saskatchewan. The objective of this study was to determine the prevalence of and predictive factors for dental treatment under GA in Saskatchewan.
