Pachyonychia congenita (PC) is a cutaneous disorder caused by a mutation in the KRT6A, KRT6B, KRT6C, KRT16 or KRT17 genes that encode a subset of epithelial keratins. The main features of the disease are painful palmoplantar keratoderma and variable nail dystrophy. In a recent study, we reported that these keratins are incorporated into mature enamel. Moreover, genetic association study showed that common polymorphisms in KRT6A, KRT6B and KRT6C are associated with increased susceptibility to tooth decay. Here we report enamel defects in a PC patient with KRT16 c...

Fluorion are pivotal anions in biology because they play an important role in dental care, treating osteoporosis, preventing tooth decay and promoting the healthy growth of bone. Studies have shown that high levels of fluoride will lead to the inactivation of the mitochondria. Therefore, it is urgent to develop a method to detect the fluoride anions in the mitochondria. Herein, we have developed a novel mitochondrial-target fluorescent probe for detecting F- in living cells. The probe exhibited excellent sensitivity and high selectivity for F- over the other relative species...

BACKGROUND: Although dental caries is a globally widespread disease, there is no consensus regarding the method that should be used for their detection. In recent decades, a variety of new methods have been proposed for measuring caries in a population. Three caries detection methods, the decayed, missing and filled (DMF) index, the International Caries Detection and Assessment System (ICDAS) and the Caries Assessment Spectrum and Treatment (CAST), were compared to provide information to guide future method choices...

BACKGROUND: Dental caries is the most common dental health problem caused by the interaction of bacteria on tooth enamel. Risk factors for dental caries include salivary composition and inadequate fluoride. However, other factors, such as standard of living, behavior, hygiene, eating habits, social status and socio-demographic factors, also contribute to the evolution of caries. Therefore, this study aimed to determine the prevalence of dental caries and associated factors among patients attending the dental clinic in Debre Tabor General Hospital in North West Ethiopia...

OBJECTIVES: Root caries has increased as a clinical problem in recent decades. However, the use of multiple waves of longitudinal follow-up data in estimating root caries increment has not been previously attempted. The aims of this study were to quantify root caries increment from a longitudinal study of older adults with 4 oral examinations over 11 years and to examine behavioural factors associated with root caries. METHODS: A secondary analysis was undertaken using data collected in 4 waves (baseline, 2-year, 5-year and 11-year) of the South Australian Dental Longitudinal Study which began in 1991/92...

Background and Objectives: The dental caries status of a population group with permanent dentition is traditionally described using decayed, missing, and filled teeth or surface (DMFT or DMFS) index, and the corresponding index for the primary dentition is dmft or dmfs. dmf value alone has certain limitations; therefore, additional measures to describe dental caries are important. Poulsen and Horowitz in 1997 described a hierarchical method to determine the severity of dental caries. Aim of the Study: The aim of the study was to determine the pattern of dental caries in 3-6-year-old children using Poulsen and Horowitz hierarchical system and to assess the usefulness of this system...
