INTRODUCTION: Children of newcomers to Canada have been identified as at moderately high risk for developing early childhood caries (ECC). The purpose of this study was to investigate the oral health of preschool children of refugee and immigrant families in Winnipeg. METHODS: Children < 72 months of age and their parent or primary caregiver were recruited through several newcomer settlement agencies, dental clinics and community programs. Parents and caregivers completed a short questionnaire with the assistance of a research team member...

The availability of proper nutrients is critical for the growth, development, maintenance, and repair of healthy dentition and oral tissues. Deficiencies particularly relevant to the dental practice are those in folate and other B complex vitamins; vitamins A, C, and D; calcium; fluoride; and protein. A lack of these nutrients affects nearly every structure in the oral cavity, causing or contributing to scurvy, cleft palate, enamel hypoplasia, poor mineralization, caries, and other pathoses. Damage to the dentition can also be observed in individuals with unhealthy habits; for example, a diet high in sugars will promote processes such as demineralization and caries...

Background: The use of doxycycline has been avoided before 8 years of age due to known dental staining caused by tetracyclines, although doxycycline differs from classical tetracyclines in many ways. Doxycycline is still an important antimicrobial agent, but its dental safety is not well studied. Objectives: To examine the state of permanent teeth after doxycycline exposure in children <8 years of age. Methods: Details of doxycycline treatment were collected from medical records...

OBJECTIVES: In Southeast (SE) Arabia, agriculture is supposed to expand around 3000 BC, but its tempo and its actual role in populations' subsistence is still debated by archaeologists. Here, we compare dental health conditions of 11 skeletal samples from coastal and inland sites, dated from the Late Neolithic (ca. 4500-3100 BC) to the Early Bronze Age (EBA), conventionally divided into Hafit (ca. 3100-2700 BC) and Umm an-Nar period (ca. 2700-2000 BC). The goal is to assess long-term trends in subsistence patterns and regional variability during the local transition to agriculture...

Auto-immune polyendocrine syndrome type 1 (APS1) also called Auto-immune Polyendocrinopathy Candidiasis Ectodermal Dystrophy (APECED) is a rare monogenic childhood-onset auto-immune disease. This autosomal recessive disorder is caused by mutations in the auto-immune regulator (AIRE) gene, and leads to autoimmunity targeting peripheral tissues. There is a wide variability in clinical phenotypes in patients with APSI, with auto-immune endocrine and non-endocrine disorders, and chronic mucocutaneous candidiasis...

Tooth enamel is mineralized through the differentiation of multiple dental epithelia including ameloblasts and the stratum intermedium (SI), and this differentiation is controlled by several signaling pathways. Previously, we demonstrated that the transcriptional coactivator Mediator 1 (MED1) plays a critical role in enamel formation. For instance, conditional ablation of Med1 in dental epithelia causes functional changes in incisor-specific dental epithelial stem cells, resulting in mineralization defects in the adult incisors...

Within the framework of the Sicily Mummy Project, the orofacial complex of a significant sample of individuals (n=111) from the Capuchin Catacombs of Palermo, Italy, was inspected. The heads and dentitions of the mummies were documented and the recorded findings described: the state of preservation of skeletal and soft tissues; dental pathologies such as carious lesions and alveolar bone loss; enamel hypoplasia; and ante- and post-mortem tooth loss. Despite limitations in data collection, the oral health of these mummies was assessed and the frequencies of pathologies were compared to those of similar populations...

Primary cilium is a solitary organelle that emanates from the surface of most postmitotic mammalian cells and serves as a sensory organelle, transmitting the mechanical and chemical cues to the cell. Primary cilia are key coordinators of various signaling pathways during development and maintenance of tissue homeostasis. The emerging evidence implicates primary cilia function in tooth development. Primary cilia are located in the dental epithelium and mesenchyme at early stages of tooth development and later during cell differentiation and production of hard tissues...

Hemangioma is a benign vascular tumor that affects 3%-10% of the population and usually does not require specific treatment due to spontaneous regression. The purpose of this paper is to present a case report of a child having been born prematurely and diagnosed with hemangioma in the head and neck, emphasizing the dentofacial changes and treatment used to provide care. Severe fibrous scars were found in the perioral region and below the ear that limited the patient's ability to open her mouth. The child exhibited anterior open bite as well as dental caries in the lower jaw, hypomineralization, and enamel hypoplasia...

Children with low levels of thyroid hormones (hypothyroidism) have delayed tooth eruption, enamel hypoplasia, micrognathia, and anterior open bite, whereas children with hyperthyroidism may suffer from accelerated tooth eruption, maxillary, and mandibular osteoporosis. However, it is still unknown whether thyroid function variations within the normal or subclinical range also have an impact on hard dental tissues in healthy children. The objective of this study was, therefore, to investigate the association between thyroid function from the fetal period until early childhood and dental development at school age...

Severe dental trauma-such as intrusion or avulsion-to the primary dentition in infants and toddlers may cause developmental disturbances in the permanent successor. In this case, a 9-year-old boy was referred for treatment due to the absence of his permanent maxillary right central incisor. The mother reported avulsion of the corresponding primary tooth when the patient was 2 years old. The radiographic examination revealed impaction and root dilaceration of the permanent tooth; therefore, the treatment plan was tooth extraction...

Anti-malarial drug resistance to chloroquine and sulfadoxine-pyrimethamine has spread from Southeast Asia to Africa. Furthermore, the recent emergence of resistance to artemisinin-based combination therapy (ACT) in Southeast Asia highlights the need to identify new anti-malarial drugs. Doxycycline is recommended for malaria chemoprophylaxis for travel in endemic areas, or in combination with the use of quinine for malaria treatment when ACT is unavailable or when the treatment of severe malaria with artesunate fails...
