American Journal of Dentistry Feb 2022To clarify how crown-to-implant ratio (C-I ratio) influences the bone biomechanically with its two components: crown height and implant length.
PURPOSE
To clarify how crown-to-implant ratio (C-I ratio) influences the bone biomechanically with its two components: crown height and implant length.
METHODS
This three-dimensional finite element study was performed in two phases. The first phase aimed to show the influence of the C-I ratio on the stresses in the peri-implant bone and the second phase to reveal the impact of each of the two components of the C-I ratio: crown height and implant length. During analyses, all models were subject to three different loading conditions - axial, buccolingual, and oblique.
RESULTS
The crown-to-implant ratio was significantly influential on stress distribution in the peri-implant bone. However, the crown's height was significantly more prominent than the length of the implant. The most substantial amount of stress was seen when long crowns were combined with off-axial loads. Being mostly dominated by the height of the crown and far less by the implant's length, the C-I ratio is not balanced and seems not to be a predictive parameter in implant dentistry.
CLINICAL SIGNIFICANCE
Crown-to-implant ratio is recommended to be assessed by its two components: crown height and implant length because the former impacts stresses significantly more than the latter.

Surgical crown lengthening (SCL) is the treatment of choice to ensure healthy tissues when subgingival tooth defects encroach on the biologic width.1 However, restorative techniques employing adhesive dentistry may provide viable alternatives to or complement SCL in select cases without the repercussions of surgical bone removal and open interproximal spaces. One such clinical technique, deep margin elevation (DME), employs a direct restoration to relocate the cervical margin of small subgingival defects of posterior teeth supragingivally. The "elevated" margin simplifies impression-making and bonding of indirect restorations, especially inlays and onlays. Recent scientific systematic literature reviews indicate favorable clinical outcomes and suggest that DME restorations made with scrupulous care have high success rates and are compatible with periodontal health. Optimal working field isolation, meticulous placement of matrices, proper bonding and buildup procedure, as well as regular maintenance and follow-up are essential for success. This article provides an overview of this approach.

Review
In dentistry, the use of biomaterial-based drug delivery systems (DDS) aiming the release of the active compounds directly to the site of action is slowly getting more awareness among the scientific and medical community. Emerging technologies including nanotechnological platforms are offering novel approaches, but the majority are still in the proof-of-concept stage. This study critically reviews the potential use of DDS in anesthesiology, oral diseases, cariology, restorative dentistry, periodontics, endodontics, implantology, fixed and removable prosthodontics, and orthodontics with a special focus on infections. It also stresses the gaps and challenges faced. Despite numerous clinical and pharmacological advantages, some disadvantages of DDS pose an obstacle to their widespread use. The biomaterial's biofunctionality may be affected when the drug is incorporated and may cause an additional risk of toxicity. Also, the release of sub-therapeutic levels of drugs such as antibiotics may lead to microbial resistance. Multiple available techniques for the manufacture of DDS may affect drug release profiles and their bioavailability. If the benefits outweigh the costs, DDS may be potentially used to prevent or treat oral pathologies as an alternative to conventional strategies. A case-by-case approach must be followed.

European Journal of Paediatric Dentistry Dec 2022The aim of this paper is to illustrate the concept of DOP Dentistry (Digital Ortho Paediatric Dentistry) in daily practice.
AIM
The aim of this paper is to illustrate the concept of DOP Dentistry (Digital Ortho Paediatric Dentistry) in daily practice.
CASE REPORT
DOP Dentistry is a new concept introduced by the authors to express the perfect integration between two disciplines that for a long time have been separated: paediatric dentistry and paediatric orthodontics. In modern dentistry it is increasingly important for the paediatric dentist to have skills and abilities that embrace both of these disciplines. To these we have to add a third element, represented by new digital technologies, as well as new bioactive ionic resin composites and biocompatible technopolymers to perform fully digital, integrated paediatric orthodontic treatments.
CONCLUSION
Based on the DOP Dentistry concept, that definitely changes the paradigm of taking care of children, new and fascinating scenarios open up, that will lead us to a more integrated management of our little patients, their needs and those of their family with a new, more ergonomic, efficient and tailor-made approach.

BACKGROUND
The aim of the current study was to investigate current dental practice in operative dentistry in Jordan, and the relationship between evidence-based dentistry in caries research and decision making in clinical practice in operative dentistry.
MATERIALS AND METHODS
This cross-sectional study was conducted through a survey of dentists in Jordan. The survey aimed to explore the degree of knowledge and practice of evidence-based dentistry in caries research the dentists possess regarding clinical decision making in operative dentistry. The sample size was composed of (5811) dentists whom registered in Jordan Dental Association database. Descriptive statistics were generated and Chi-square test was used to examine associations between the different variables and the significance level was set at P < 0.05.
RESULTS
4000 responses were collected from the web-survey, response rate (68.83%). Nearly half of the surveyed dentists focus on the chief complaint of their patients (n = 2032, 50.8%) rather than doing full mouth assessment. Nearly two-thirds of dentists (n = 2608, 65.2%) treat lesions confined to enamel with operative treatment. Half of dentists use operative treatment when asked about the routine management of radiographically detected proximal caries confined to enamel. When treating incipient lesions, the majority (n = 3220, 80.5%) use preventive treatment. Three-quarters of dentists (n = 2992, 74.8%) treat deep dentinal caries by removing just the soft infected carious dentin, and treated old failed restorations with replacement.
CONCLUSION
In operative dentistry, the evidence-based research is not implemented clinically. To optimize relationship between evidence-based dentistry and clinical decision-making, dental curriculum has to be updated and modified constantly.

Review
OBJECTIVES
The aim of this review to overview three-dimensional (3D) printing technologies available for different dental disciplines, considering the applicability of such technologies and materials development.
MATERIALS AND METHODS
Source Arksey and O'Malley's five stages framework using PubMed, EMBASE, and Scopus (Elsevier) databases managed this review. Papers focusing on 3D printing in dentistry and written in English were screened. Scientific productivity by the number of publications, areas of interest, and the focus of the investigations in each dental discipline were extracted.
RESULTS
Nine hundred thirty-four studies using 3D printing in dentistry were assessed. Limited clinical trials were observed, especially in Restorative, endodontics, and pediatric dentistry. Laboratory or animal studies are not reliable for clinical success, suggesting that clinical trials are a good approach to validate the new methods' outcomes and ensure that the benefits outweigh the risk. The most common application for 3D printing technologies is to facilitate conventional dental procedures.
CONCLUSIONS
The constantly improving quality of 3D printing applications has contributed to increasing the popularity of these technologies in dentistry; however, long-term clinical studies are necessary to assist in defining standards and endorsing the safe application of 3D printing in dental practice.
CLINICAL RELEVANCE
The recent progress in 3D materials has improved dental practice capabilities over the last decade. Understanding the current status of 3D printing in dentistry is essential to facilitate translating its applications from laboratory to the clinical setting.

Review
The aim of this review is to investigate the growth of diversity and inclusion in global academic dental research with a focus on gender equality. A diverse range of research methodologies were used to conduct this review, including an extensive review of the literature, engagement of key informants in dental academic leadership positions around the world, and review of current data from a variety of national and international organizations. Results provide evidence of gender inequalities that currently persist in dental academics and research. Although the gender gap among graduating dental students in North America and the two most populous countries in Europe (the United Kingdom and France) has been narrowed, women make up 30% to 40% of registered dentists in countries throughout Europe, Oceania, Asia, and Africa. In academic dentistry around the globe, greater gender inequality was found to correlate with higher ranking academic and leadership positions in the United States, United Kingdom, several countries in European Union, Japan, and Saudi Arabia. Further disparities are noted in the dental research sector, where women make up 33% of dental researchers in the European Union, 35% in North America, 55% in Brazil, and 25% in Japan. Family and societal pressures, limited access to research funding, and lack of mentoring and leadership training opportunities are reported as also contributing to gender inequalities. To continue advancing gender equality in dental academia and research, efforts should be geared toward the collection and public dissemination of data on gender-specific distributions. Such evidence-driven information will guide the selection of future strategies and best practices for promoting gender equity in the dental workforce, which provides a major pipeline of researchers and scholars for the dental profession.
