This historical narrative highlights the origin and development of the dental hygiene profession in South Korea. The legacy of early American missionaries to Korea includes profound and long-lasting contributions in medicine, education and theology. Many of Korea's top universities today have their roots in the missionary schools of the late nineteenth century, including Yonsei University, home...

Dental hygiene is defined as the science and practice of the recognition, treatment and prevention of oral diseases. The history of dental hygiene research is considered in the context of the development of the discipline and an emerging infrastructure. Research-related events supporting the growth and maturation of the profession are considered from the early years to the most recent. The bene...

Dentistry is likely to be revolutionized by biological therapies based on growth and differentiation factors that accelerate and/or induce a natural biological regeneration. Induced pluripotent stem cell-based therapy for treating genetic disorders has become an interesting field of research in recent years. However, there is a paucity of information regarding the applicability of induced pluri...

D ental care use patterns have been shifting dramatically over the past decade. More children than ever are visiting the dentist. But dental care use among adults is declining steadily, among all income groups, a trend that emerged well before the recent economic downturn. These shifting dental care use patterns have had important implications. National dental care expenditure began to grow at ...

Dental implants have become an accepted treatment modality for aging patients with either completely or partially edentulous arches. However, growing patients with congenitally missing primary and/or permanent teeth often need dental implant treatment, even before puberty, for optimum functional and/or psychosocial development. From a developmental perspective, dental implants cannot accompany ...

Dental fluorosis is a developmental disturbance of dental enamel, caused by successive exposures to high concentrations of fluoride during tooth development, leading to enamel with lower mineral content and increased porosity. The severity of dental fluorosis depends on when and for how long the overexposure to fluoride occurs, the individual response, weight, degree of physical activity, nutri...

Rubinstein-Taybi Syndrome (RTS) is a rare multiple congenital syndrome characterized by distinctive facial features, mental and growth retardation, broad thumbs and great toes. This case report describes the oro-dental manifestations, as well as, orthodontic evaluation of a 9-year-old male patient who had RTS. The remarkable oro-dental features were talon-like cingulum on maxillary central inci...

A chronology of dental development in Pan troglodytes is arguably the best available model with which to compare and contrast reconstructed dental chronologies of the earliest fossil hominins. Establishing a time scale for growth is a requirement for being able to make further comparative observations about timing and rate during both dento-skeletal growth and brain growth. The absolute timing ...

This study investigated the relationships between the stages of calcification of teeth and cervical vertebral maturation. The sample consisted of 295 subjects (129 male and 166 female), mean age 13.36 ± 2.65 (range 7-18) years. Dental age was evaluated from panoramic radiographs according to the method of Demirjian. Cervical vertebral maturation was determined on lateral cephalometric radiograp...
