Maximizing Results with Minimal Preparation Veneer Restoration

Restoration of anterior dentition is always a challenge to most dental practitioners. Contemporary materials have adopted the physical properties of dental hard tissues which protected the restored tooth successfully and are well documented. Veneer restoration to enhance anterior cosmetic is indeed a predictable treatment for the correction of minimal malalignment and morphological flaws. However, over preparation of tooth could lead to breakage of veneer. Careful planning could yield a superior outcome without excessive tissue loss and therefore enhance longevity. This lecture aims to provide to the participants of veneer restoration with minimum prep, maximum result.

The Role of Mouth Rinse in Chemical Plaque Control

Oral hygiene is an important element in the prevention of oral diseases. While the main stream of maintaining good oral hygiene is by mechanical plaque control, there are still situations where chemical plaque control is needed. Out of all the currently available chemical plaque control methods, mouth rinse is the most easily available and widely used product. Currently there are a lot of mouthrinse products with different active ingredients in the market with different claimed actions. In this seminar, an overview of the available mouth rinse products will be given. A special focus will be given to chlorhexidine, which is a common mouth rinse used in relation to the management of periodontal disease. The related evidence for its use, and prevention of caries and periodontal disease will be discussed and recommendations on the use of these products will also be given.

An Adjunctive Use of Photonic Dentistry in Cariology: Early Detection & Therapy

Despite considerable advances in dentistry, dental caries remains one of the most common and unsolved human infectious disease. Around 90% of young population in the United States has dental caries, while out of all dentate adults almost 94% have evidence of coronal caries. It was forecasted that such occurrence of dental caries is one the driver that propels the growing demand for dental services. There is an urge in demand of adjunctive use of photonic (laser and light) dentistry in a multidisciplinary, minimally invasive and preventive approach that would encourage regular patient attendance to allow for patient education, early caries detection and intervention. Researchers in 1940s demonstrated that by exposure to photons from the sunlight provided a mean of dental caries prevention. A survey of 12-14 years old boys in rural and semirural areas of the United States reported that a 30% increase in the annual exposure to sunshine correlated with a 40% reduction in the incidence of dental caries. Today, Photons technology underpins a wide range of adjunctive applications in daily dental practice from digital-light-processing 3D scanning, to fluorescent-guided caries and oral cancer early detection, and to photo-ablation, photobiomodulation, caries prevention, photo-activated-disinfection and esthetic therapy. The aim of this lecture is to present the “ABCD of light in Cariology”, an adjunctive use of photonic (laser and light) dentistry in a multidisciplinary, minimally-invasive and preventive approach that would encourage regular patient attendance to allow for patient education, early caries detection and intervention.

Teeth for a Lifetime and Dental Materials to Support Them All the Way

The world average life expectancy is currently beyond 85 years of age in developed countries. More elderly patients are retaining their natural teeth longer into old age--thereby necessitating ongoing restorative dentistry input for their maintenance. Most of the materials that are currently used for direct restorations were developed less than 50 years ago and there is no evidence of such a longevity for these restorations, that would be more likely replaced, renewed or simply refreshed in the lifespan of an aging individual.

Clinical Applications of Silver Diamine Fluoride

Silver diamine fluoride (SDF) is used to control early childhood caries, arrest root caries of older adults, prevent fissure caries and secondary caries, desensitise hypersensitive teeth, remineralise hypomineralised teeth, prevent dental erosion, detect carious tissue during excavation and manage infected root canals. It is commonly available as a 38% solution containing 255,000 ppm silver and 44,800 ppm fluoride ions. Silver is an antimicrobial and inhibits the growth of cariogenic biofilm. Fluoride promotes remineralisation and inhibits the demineralization of teeth under acid challenge. SDF also prevents degradation of dentine collagen through inhibiting proteolytic peptidases in dentine and saliva. Current evidence showed proper use of SDF does not cause dental fluorosis. SDF arrests deep caries without eliciting additional harm to the pulp. Indirect pulp capping with SDF causes none or mild inflammatory pulpal response. However, direct SDF application to dental pulp causes pulp necrosis. Furthermore, SDF stains carious lesions black. Patients must be well informed before treatment. SDF therapy is simple, painless, non-invasive and inexpensive. Both clinicians and patients accept it generally well. SDF therapy requires simple armamentarium and minimal support. Hence, it can be used for people currently unable to tolerate more involved dental treatment. In 2021, The World Health Organization included SDF as an essential medicine that is effective and safe to meet the most important needs in a health system for adults and children.

Disruptive Innovation in Oral Healthcare

Science and technology continuously advance in most if not all industries including, healthcare. Many of the advances are incremental in nature and improve the performance and/or lower the costs of well-established products or services. Disruptive innovations are those that create new applications or markets and ultimately, make established technologies obsolete. At an early stage, disruptive innovations often underperform compared to established technologies, but have attributes that are of value in new markets or for new applications. The performance of truly disruptive innovations often improves rather quickly and over time, surpass that of established technologies. Examples of disruptive innovations will be presented, and an outlook provided on which recent advances hold promise to disrupt oral healthcare in the future.

Evidence-based Caries Prevention for Children

Early childhood Caries (ECC) is one of the most prevalent childhood chronic diseases worldwide, affecting over 620 million children. Not only dental caries among children are costly to treat, ECC can have profound and prolonged repercussions, significantly impacting on the children’s quality of life, future dental development and growth. Dental caries has been disproportionally affecting particular high-risk groups, which arouse researchers’ interest to identify these “high-risk” children and the associated risk factors. Preventing the establishment of dental caries is the key to successfully tackle the problem, hence different potential caries risk factors and target-specific preventive measures will be discussed with the audience.

Effective Prevention of Periodontal Diseases in Practice

Prevention of periodontal diseases has long been a major clinical challenge. Low awareness of patients on periodontal diseases, difficulties in motivation and communication of risks, and difficulties in delivering preventive treatments in daily practices may be some of the many reasons why in many cases the periodontal diseases were not controlled until it was too late, when complex, challenging and costly rehabilitation is needed. With the aim to ease implementation of preventive measures in everyday practice, this one-hour seminar will focus on how to practically assist in behavioural change (especially in self-performed oral hygiene), evidence-based recommendations on recent home care products and updates on the recent European Federation of Periodontology (EFP) S3 Level Clinical Practice Guideline in relation to prevention of periodontal diseases.
