Strontium content and collagen-I coating of Magnesium–Zirconia–Strontium implants influence osteogenesis and bone resorption
Our objective was to study the role of Collagen type-I (Col-I) coating on Magnesium–Zirconia (Mg–Zr) alloys, containing different quantities of Strontium (Sr), in enhancing the in vitro bioactivity and in vivo bone-forming and mineralisation properties of the implants. MC3T3-E1 osteoblast cell line was used to analyse the in vitro properties of Col-I coated and uncoated alloys. Cell viabili...


Comparison of microtensile bond strength of a resin composite to enamel conditioned by acid etching and Er,Cr:YSGG laser in human primary teeth
This study was designed to compare the bond strength of composite resin restorations on the buccal surface of primary human canine after conditioning by conventional acid etching and Er,Cr:YSGG laser. Twenty sound primary canines were cut buccolingually into two halves and each half was randomly placed in Er,Cr:YSGG laser or acid etch group. The samples in the acid etch group were etched with 3...
Developing evidence-based dentistry skills: how to interpret randomized clinical trials and systematic reviews
Decision-making based on reliable evidence is more likely to lead to effective and efficient treatments. Evidence-based dentistry was developed, similarly to evidence-based medicine, to help clinicians apply current and valid research findings into their own clinical practice. Interpreting and appraising the literature is fundamental and involves the development of evidence-based dentistry (EBD...


Association between breastfeeding duration, non-nutritive sucking habits and dental arch dimensions in deciduous dentition: a cross-sectional study
This cross-sectional retrospective study was conducted to determine association between breastfeeding duration, non-nutritive sucking habits, dental arch transverse diameters, posterior crossbite and anterior open bite in deciduous dentition.415 children (228 males and 187 females), 4 to 6 years old, from a mixed Indian population were clinically examined. Based on written questionnaire answere...
Regenerative Endodontic Treatment of an Infected Immature Dens Invaginatus with the Aid of Cone-Beam Computed Tomography
Dens invaginatus is a developmental anomaly that results in an enamel-lined cavity intruding into the crown or root before the mineralization phase. This report presents regenerative endodontic treatment of a necrotic immature tooth with Oehler’s type III dens invaginatus of a nine-year-old female patient. A diagnosis of dens invaginatus (Oehler’s type III) and a large periapical lesion was...


Predicting Cancer Risks from Dental Computed Tomography
Dental computed tomography (CT) has become a common tool when carrying out dental implants, yet there is little information available on its associated cancer risk. The objective of this study was to estimate the lifetime-attributable risk (LAR) of cancer incidence that is associated with the radiation dose from dental CT scans and to evaluate the effect of scan position, sex, and age on the ca...
LPS Induces Pulp Progenitor Cell Recruitment via Complement Activation
Complement system, a major component of the natural immunity, has been recently identified as an important mediator of the dentin-pulp regeneration process through STRO-1 pulp cell recruitment by the C5a active fragment. Moreover, it has been shown recently that under stimulation with lipoteichoic acid, a complex component of the Gram-positive bacteria cell wall, human pulp fibroblasts are able...

Predicting Severe Pain after Root Canal Therapy in the National Dental PBRN
Some patients experience severe pain following root canal therapy (RCT) despite advancements in care. We sought to identify factors, which can be measured preoperatively, that predict this negative outcome so that future research may focus on preemptive steps to reduce postoperative pain intensity. Sixty-two practitioners (46 general dentists and 16 endodontists) who are members of the National...
Understanding Treatment Effect Mechanisms of the CAMBRA Randomized Trial in Reducing Caries Increment
The Caries Management By Risk Assessment (CAMBRA) randomized controlled trial showed that an intervention featuring combined antibacterial and fluoride therapy significantly reduced bacterial load and suggested reduced caries increment in adults with 1 to 7 baseline cavitated teeth. While trial results speak to the overall effectiveness of an intervention, insight can be gained from understandi...

Vitamin and mineral supplements: Friend or foe when combined with medications?
Given the prevalence of vitamin and mineral supplement use among consumers and the potential for vitamin- and mineral-drug interactions, as well as oral and systemic adverse effects of excess consumption, oral health care providers (OHCPs) should ask all patients about their use. The challenges for OHCPs are how to recognize oral and systemic manifestations of these interactions and how to safe...
Accuracy of computer-aided design/computer-aided manufacturing-generated dental casts based on intraoral scanner data
Little is known about the accuracy of physical dental casts that are based on three-dimensional (3D) data from an intraoral scanner (IOS). Thus, the authors conducted a study to evaluate the accuracy of full-arch stereolithographic (SLA) and milled casts obtained from scans of three IOSs. The authors digitized a polyurethane model using a laboratory reference scanner and three IOSs. They sent t...

Using hand-held dental x-ray devices: Ensuring safety for patients and operators
Since the introduction of hand-held x-ray units in dentistry, a few inexpensive devices have emerged that lack the necessary safety measures and failed to meet U. S. Food and Drug Administration (FDA) standards. They are advertised actively and sold online in the United States. The authors present several safety issues associated with an imported hand-held x-ray device that has not been cleared...
The influence of hemostatic agents on dentin and enamel surfaces and dental bonding: A systematic review
Hemostatic agents have been used clinically in dentistry for many years to control bleeding. The authors reviewed scientific publications in which researchers investigated the effects of hemostatic agents on dentin and enamel surfaces and on bonding of adhesive systems and resin cements. Types of Studies Reviewed. The authors screened PubMed and Scopus databases for studies in English published...
Twenty-month follow-up of occlusal caries lesions deemed questionable at baseline: Findings from The National Dental Practice-Based Research Network
A questionable occlusal caries (QOC) lesion can be defined as an occlusal surface with no radiographic evidence of caries, but caries is suspected because of clinical appearance. In this study, the authors report the results of a 20-month follow-up of these lesions. Fifty-three clinicians from The National Dental Practice-Based Research Network participated in this study, recording lesion chara...
Force-controlled biting alters postural control in bipedal and unipedal stance
Human posture is characterised by inherent body sway which forces the sensory and motor systems to counter the destabilising oscillations. Although the potential of biting to increase postural stability has recently been reported, the mechanisms by which the craniomandibular system (CMS) and the motor systems for human postural control are functionally coupled are not yet fully understood. The ...
