Coronavirus disease (COVID-19) is a major threat to the health and prosperity of human life at present. It has resulted in loss of thousands of lives globally and has brought countries to the brink of economic, social, and health collapse. A major issue of this infection is the ease with which it transmits through salivary droplets and its survival for long durations outside the body. Therefore, its early detection is critical in prevention, diagnostic, and management efforts of COVID-19 patients. Loss of taste and smell is one of the early symptoms reported in these patients and the virus is abundantly found in the salivary secretion of the infected symptomatic and asymptomatic patients...

OBJECTIVES:  This in vitro study aimed to characterize the mineral content and surface and cross-sectional morphology of enamel and dentin tissues treated with a 1450 ppm fluoride-containing toothpaste with REFIX technology. MATERIALS AND METHODS:  Bovine enamel blocks ( n = 5) were obtained (4 × 4 × 6 mm), demineralized (artificial caries lesion), and treated (pH cycling and brushing with the toothpaste). During the pH cycling, which lasted for 7 days (demineralization and remineralization took 6 and 18 hours, respectively), the enamel was brushed for 5 minutes using an electric toothbrush before being immersed in a remineralizing solution...

OBJECTIVE: To characterize lactobacilli isolated from residual carious dentin after selective caries removal (SCR), by observing the changes detected in their prevalence, diversity, and cariogenic potential after starvation stress caused by cavity sealing (CS). DESIGN: Lactobacilli were cultured from carious dentin lesions (n = 16 patients) treated in a clinical trial, three months before and after CS. Presumptive lactobacilli were selected, isolated, and analyzed by Gram staining...

Regenerative therapies such as dental pulpal revascularization appear as an option for traumatized immature permanent teeth. However, the triple antibiotic paste - TAP (metronidazole, minocycline, and ciprofloxacin), used for these therapies, can generate cytotoxicity and dentin discoloration. In contrast, host defense peptides (HDPs) are promising antimicrobial and immunomodulatory biomolecules for dentistry. This study aimed to evaluate in vitro the antimicrobial activity (against Staphylococcus aureus and Enterococcus faecalis) and the immunomodulatory potential (by the evaluation of IL-1α, IL-6, IL-12, IL-10, TNF-α and NO, in RAW 264...

OBJECTIVES: Arresting active initial caries lesions is part of the modern caries controlling system. Resin infiltration (RI) system has been found a promising method in arresting interproximal initial lesions. The aim was to investigate whether RI arrests progression of active caries lesions. MATERIALS AND METHODS: Participants (n = 20) of the retrospective study were patients in the Dental Teaching Unit, City of Oulu, Finland, mean age 26 years (SD5.2). Indication for RI was radiographically diagnosed progressing (ICDAS 1-3) interproximal lesions (n = 54)...

Development of gingival enlargement and periodontitis is described in a young dwarf mongoose. Repeated treatments resulted in gingival resection and histologic evaluation however gingival enlargement was ultimately responsive to extraction of associated teeth. In cases such as these, surgical extraction of teeth associated with severe recurrent gingival enlargement should be considered to avoid the stress and risk of repeated immobilizations.

It is not uncommon to encounter post-surgical complications after horizontal guided bone regeneration (GBR). The primary aim of this review was to evaluate the incidence and types of complications that occur after horizontal GBR and propose management strategies to deal with these clinical situations. A secondary aim was to conduct a histomorphometric review of the wound healing process at sites that experienced post-surgical complications after GBR. A keyword search of MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for studies published in English from January 2015 to January 2020 was conducted for the primary aim and 23 studies were selected...

Human health is linked to environmental health. Pollutants or disease-causing microbes released into the environment through human activity or natural disasters affect communities' air quality, water or food supply, and, ultimately, the livelihoods of residents. Oral health care (OHC) professionals, including dental hygienists (DHs), use vast amounts of resources in their daily clinical operations, which contribute to the global pollution burden and climate change. Canadian OHC professionals are largely missing from the environmental sustainability dialogue, despite their commitment to the holistic well-being of their clients and communities they support...

Background: Women involved with the criminal justice system are often marginalized or vulnerable and may face oral health inequities. Through a community-engaged program at a Canadian university, dental hygiene students provided preventive care at an organization supporting this population. This study explored the impact of these oral care services from client and organization staff perspectives. Methods: One focus group with 6 clients, 2-person interviews with 4 clients, individual interviews with 3 clients, and one focus group with 4 organization staff members were conducted...

Background: Mini-esthetics is an important concept in orthodontics concerned with relatedness of dentition to the face. Purpose: We compared the perception of altered smile esthetics between orthodontists, dentists, and laypeople in Riyadh, Saudi Arabia. Patients and Methods: A total of 216 participants (orthodontists, dentists, and laypeople) were conveniently surveyed. An image representing the ideal smile was altered in terms of buccal corridor, gingival display, and midline diastema...

During the current coronavirus disease 2019 (COVID-19) pandemic, dental education and training requiring face-to-face interaction must prioritize infection prevention and the safety of students, staff, and patients. In July 2020, the Association for Dental Education, Asia Pacific (ADEAP) published safety guidelines for safe dental education during the COVID-19 pandemic. These guidelines summarize ADEAP recommendations for classroom-based courses, reopening of simulated training courses and dental clinics, and provision of clinical skills training courses in dentistry during the COIVID-19 pandemic...

PURPOSE: The aim of this study was to compare the influence of the number of coronal walls and post-endodontic restorations on the mechanical strength of 165 recently extracted endodontically treated maxillary premolars. METHODS: The teeth were divided into 3 control (no post) and 3 test groups according to the number of residual walls. Each test group was divided into subgroups according to the type of post-endodontic restoration (single, oval, and multi-post techniques)...

PURPOSE: Whether it is possible to prevent mechanical stress on teeth via an occlusal splint remains to be clarified. This study aimed to assess the same by simultaneously recording the occlusal pressure and strain on the teeth in humans. METHODS: Eleven participants (five women and six men; mean age 25.7 years) were enrolled in this study. Hard and soft oral appliances were fabricated for the maxillary arch of each participant. The strain on the four target teeth (right maxillary and mandibular first premolars, and first molars) and occlusal pressure were concurrently measured, while the participants performed maximum voluntary teeth clenching under each condition (hard, soft, or no occlusal splint)...
