Primary cilia are nearly ubiquitous, cellular projections that function to transduce molecular signals during development. Loss of functional primary cilia has a particularly profound effect on the developing craniofacial complex, causing several anomalies including craniosynostosis, micrognathia, midfacial dysplasia, cleft lip/palate and oral/dental defects. Development of the craniofacial complex is an intricate process that requires interactions between several different tissues including neural crest cells, neuroectoderm and surface ectoderm...

Tissue engineering has emerged as a potential therapeutic option for dental problems in recent years. One of the policies in tissue engineering is to use both scaffolds and additive factors for enhancing cell responses. This study aims to evaluate and compare the effect of three types of biofactors on poly-caprolactone-poly-ethylene glycol-poly caprolactone (PCL-PEG-PCL) nanofibrous scaffold on human dental pulp stem cell (hDPSCs) engineering. The PCL-PEG-PCL copolymer was synthesized with ring opening polymerization method, and its nanofiber scaffold was prepared by electrospinning method...

A new clinic conception, healthy cosmetic management (HCM), was innovated introduced into diagnose and treatment of patients with high caries risk. The priority of HCM should be given to aesthetic restoration of teeth, taking consideration of the conserving of tissue and pulp of teeth and the balance between health and aesthetics, which may reach to the goal of the individual clinic treatment. HCM includes five steps: 1) caries risk assessment; 2) detection of initial caries; 3) digital aesthetic design; 4) minimally invasive therapy; 5) behavior management of caries and doctor-patient communication pattern...

The developing tooth offers a model for the study of ectodermal appendage organogenesis. The signaling networks that regulate tooth development have been intensively investigated, but how cell biological responses to signaling pathways regulate dental morphogenesis remains an open question. The increasing use of ex vivo imaging techniques has enabled live tracking of cell behaviors over time in high resolution. While recent studies using these techniques have improved our understanding of tooth morphogenesis, important gaps remain that require additional investigation...

INTRODUCTION: The sense of coherence (SOC) has been suggested to be highly applicable concept in the public health area because a strong SOC is stated to decrease the likelihood of perceiving the social environment as stressful. This reduces the susceptibility to the health-damaging effect of chronic stress by lowering the likelihood of repeated negative emotions to stress perception. MATERIALS AND METHODS: The demographic data and general information of subjects' oral health behaviors such as frequency of cleaning teeth, aids used to clean teeth, and dental attendance were recorded in the self-administered questionnaire...

Purnima Hernandez, April N Kisamore
BACKGROUND AND OVERVIEW: There are no guidelines about when breast-feeding (BF) should be discontinued. In addition, investigators have not examined patient-provider communication regarding weaning strategies based on function and oral care management during prolonged BF. CASE DESCRIPTION: Suggestions to wean do not include strategies about how to achieve discontinuance. The authors conducted this case study to assist care providers in facilitation of such discussions with parents to minimize the risk of developing dental caries in older children who are breast-fed...

PURPOSE: Sedation is becoming more commonplace for pediatric patients undergoing minor procedures. Fortunately, electronic monitors have contributed to a reduction in the associated respiratory adverse events (RAEs). To test the hypothesis that adding the pretracheal stethoscope (PTS) to standard monitoring methods (SMMs) may improve RAE detection in sedated pediatric dental patients, the frequency of RAEs detected by SMMs (i.e. visual observation, capnography, and pulse oximetry) was compared to that detected by SMMs alongside continuous PTS auscultation...

In a dental implant system, the value of stress and its distribution plays a pivotal role on the strength, durability and life of the implant-bone system. A typical implant consists of a Titanium core and a thin layer of biocompatible material such as the hydroxyapatite. This coating has a wide range of clinical applications in orthopedics and dentistry due to its biocompatibility and bioactivity characteristics. Low bonding strength and sudden variation of mechanical properties between the coating and the metallic layers are the main disadvantages of such common implants...

Enamel demineralization is destructive, esthetically compromised, and costly complications for orthodontic patients. Nano-sized amorphous calcium phosphate (NACP) has been explored to address this challenge. The 20% NACP-loaded ortho-cement notably exhibited favorable behavior on reducing demineralization of enamel around brackets in a caries model designed to simulate the carious attack. The 20% NACP-loaded ortho-cement markedly promotes higher calcium and phosphate release at a low pH, and the mineral loss was almost two fold lower and carious lesion depth decreased the by 1/3...
