Accuracy and Reliability of Intraoral Scanners: Are They the Better Option?
This study also compared the accuracy, reliability, and ease of use of different types of intraoral scanners available and correlated the results with the different scanning technologies.Recent FindingsDigital impressions offer the same level of accuracy as conventional impressions regarding fabrication of crowns, fixed dental prostheses (FDPs), implant-supported crowns, and short-span FDPs with marginal gap values within the clinically acceptable range (<120 μm). However, for full-arch restorations, conventional impressions result in better accuracy.SummaryFurther enhancements needs to be undertaken regarding intrao...

Periodontal Medicine —New Diagnostic Opportunities
We examined the literature on periodontal medicine to determine how this field has influenced the diagnosis of periodontal diseases and the search for biomarkers in oral fluids.Recent FindingsPeriodontal medicine has pushed the boundaries of biomarker discovery in oral fluids, where several analytes present in serum can be detected and potentially explored for the diagnosis of systemic conditions. The study of mechanisms linking oral and systemic diseases has also contributed to advances in our understanding of systemic modulation of the subgingival microenvironment and its effects on gingival crevicular fluid components a...

Esthetic Crown Lengthening: Contemporary Guidelines for Achieving Ideal Gingival Architecture and Stability
AbstractPurpose of ReviewThe achievement and maintenance of ideal gingival margin levels and architecture constitute essential requirements for esthetic crown lengthening procedures. The use of a scalpel blade and ancillary mechanical armamentarium to sculpt the gingival margins may not be the most efficient or accurate surgical method available, and this review will consider the use of contemporary alternatives. Additionally, the fact that gingival margin levels are often not stable following esthetic crown lengthening surgery is a phenomenon that has perplexed clinicians. The purpose of this article is to review the pert...

Mastication and Gut Hormones —Are There Any Associations?
AbstractPurpose of ReviewThe human gastrointestinal tract (stomach, intestine, and pancreas) secretes more than 20 different hormones. These hormones influence many physiological processes and may contribute to the risk of developing several chronic diseases. Consequently, a better understanding of the factors that influence their secretion and action may lead to a new approach in preventing or treating chronic disease. Several factors are known to influence the gut hormone response including the macronutrient content or the physical characteristics of the ingested meal. However, despite having a major role in the digestio...

Clinical Performance of All-Ceramic Dental Restorations
AbstractPurpose of ReviewThe study aims to assess the current scientific evidence on the clinical performance of all-ceramic dental restorations.Recent FindingsSilica-based and oxide-based ceramics provide esthetic treatment alternatives but rely on proper case selection and handling. Clinical long-term success rates are generally high for both tooth-supported and implant-supported restorations. Due to limited flexural strength and high brittleness, silica-based ceramics are limited in respect to clinical indications and their success greatly depends on resin bonding for final insertion. High-strength oxide-based ceramics ...

Digital Workflow in Implant Dentistry
AbstractPurpose of ReviewImplant dentistry is going through a digital revolution. Through the development of new equipment and their corresponding workflows, the diagnosis and treatment of our patients are becoming simpler and more efficient. This review examines the workflows and techniques that apply digital technology to the pre-operative planning stages, the surgical placement, and the prosthetic phases of implant treatment.Recent FindingsWith the current influx of new hardware and software into the market, dental technology has the potential to infiltrate every area of clinical implant dentistry. Its use generally beg...

Malnutrition and Oral Disease in the Elderly ––Is There Any Bidirectional Relationship?
AbstractPurpose of ReviewThe purpose of the review is to find recent evidence for a bidirectional relationship between oral diseases and malnutrition.Recent FindingsElectronic search of MEDLINE using PubMed and a manual search of key journals for literature published in English between January 2013 and June 2016, was conducted and resulted in the selection of 25 papers. These selected studies comprised 19 observational studies, which included 17 cross-sectional and 2 longitudinal designs, and 6 interventional studies. A majority of the studies demonstrated a significant association between the following conditions in older...

Epidemiological Evidences for the Association of Obesity and Metabolic Disorders with Oral Diseases
AbstractPurpose of ReviewObesity is the underlying cause of many chronic diseases and affects overall health. Obesity and obesity-related metabolic disorders, particularly, metabolic syndrome and diabetes, have been recognized to be associated with oral diseases. This review describes the recent evidence from epidemiological studies investigating the effect of obesity and metabolic disorders on oral diseases, including dental caries and periodontal disease in adults.Recent FindingsLongitudinal studies indicate the direction of association that obesity and diabetes affect periodontal disease.

Malnutrition and Oral Health in Children
AbstractPurposeThe purpose of this paper is to review the effects of malnutrition on children ’s oral health.Recent FindingsMalnutrition negatively affects the development of craniofacial structures and teeth. Nutrient deficiencies during amelogenesis and dentinogenesis lead to defective tooth structures, which tend to harbor cariogenic bacteria. The role of vitamin D in prevention of dental caries is inconclusive. Some researchers believe dental caries is not multifactorial nor transmissible because caries cannot develop without sugars. There is conflicting information in relation to the effects of malnutrition in tooth...

The Influence of Periodontal Burden on Metabolic Control of Diabetes —Myth or Reality?—from a Nutritional Perspective
This report summarizes current understanding on the underlying mechanisms.Recent FindingsAll recent studies supporting the beneficial effects of periodontal treatment have common features: (1) clinically, periodontal disease in diabetics is relatively severe, (2) the subjects exhibit elevated hs-CRP level, which declines following periodontal treatment, and (3) the subjects generally do not exhibit morbid obesity. Nevertheless, the subjects with higher hs-CRP appear to develop more mature adipose tissues than the subjects with lower hs-CRP.SummaryInflammatory immune cells have been reported to migrate into adipose tissue, ...

Taste Sensing Systems Influencing Metabolic Consequences
AbstractRecent FindingsThe taste information contributes to evaluate the quality and nutritional value of food before it is ingested, and thus, is essential for maintaining nutritive homeostasis within the body. Recent studies revealed that taste sensitivity is modulated by humoral factors such as hormones. Angiotensin II is a key hormone regulating sodium and water balance. Investigations of its involvement in the taste system revealed that angiotensin II suppresses the gustatory NaCl responses (amiloride-sensitive component) and enhances sweet taste sensitivity without affecting umami, sour, and bitter responses in mice....
