The clinical use of fluorides for the prevention of dental caries in children
“The clinical use of fluorides for the prevention of dental caries in children”.
Professor Jack Toumba, Paediatric Dentistry, School of Dentistry, Leeds, U.K.
The mainstay of preventive measures are the judicious use of fluoride (F), plaque control, fissure sealants and sensible dietary advice. It is the activity of the fluoride ion in the oral fluid that is of most importance in reducing the solubility of the enamel rather than a high content of fluoride in enamel. This is now the most widely accepted view of the role of fluoride in the prevention of dental caries. Fluoridated toothpastes have had the greatest impact on combating dental caries, which has declined dramatically since their introduction in the early 1970’s. There are numerous different toothpaste formulations with differing fluoride concentrations for use by children and adults. Fluoride is also available clinically in tablets and drops, gels, rinses, varnishes and on a community level in water, salt and milk. Cochrane reviews have proven the clinical effectiveness of many clinical fluoride products. The latest fluoride research is investigating the use of slow-release devices for the long term intra-oral provision of fluoride. F over-dosage leads to acute and chronic toxicity. Today the use of fluoride dental products are as safe as can be and this presentation will discuss these issues and highlight the safe use of fluoride in Paediatric Dentistry.
Svante Twetman is a specialized pediatric dentist and professor of cariology at the Faculty of Health and Medical Sciences, University of Copenhagen, Denmark. He graduated from dental school in 1974 and holds the PhD and Odont Dr degrees from Karolinska Institute, Stockholm, Sweden. The research is focused on the role of oral biofilms in health and disease, risk assessment and caries prevention in children and young adults. The most recent topics deal with biofilm control through the use of pre- and probiotic bacteria for maintenance of oral health in childhood. The research has to a large extent been performed in clinical settings but linked to explorative studies in the laboratory. Dr. Twetman has authored and co-authored over 230 peer-reviewed papers and lectured in all continents. He is a consultant of the Swedish Agency for Health Technology Assessment and Assessment of Social Services and thereby involved in systematic reviews and mapping of knowledge gaps. Among several awards, he received the IADR Distinguished Scientist Award in 2010 and the IADR Borrow Award in 2011.
Caries prevention beyond fluoride – biofilm control with pre- and probiotics
Svante Twetman, Department of Odontology, Faculty of Health and Medical Sciences, University of Copenhagen, Denmark
Recent insights concerning the importance of a balanced and diverse microbiome in oral biofilms for the maintenance of health have brought a novel concept to dentistry; biofilm control rather than plaque eradication and restorative care. Therefore, the interest in using prebiotic agents and probiotic bacteria for the management of oral diseases has emerged in recent years, although the exact mechanisms of action are still unknown. The lecture will provide a brief background on the role of oral biofilms in health and disease and the potential role of prebiotics, such as arginine, and beneficial bacteria to prevent dysbiosis. The main vehicles for administration are toothpaste, dairy products or tablets/lozenges/drops. Clinical trials have shown that arginine can moderate the composition of the oral biofilm and boost the caries-preventive of fluoride in children and elderly. Systematic reviews have also displayed good evidence of an antagonistic role for probiotic lactobacilli and bifidobacteria against salivary mutans streptococci, while the effect on lesion development is controversial. Probiotic interventions early in life seem particularly promising since the timing and sequence of exposure to beneficial and harmless bacteria has a strong influence on the composition and development of the oral biofilm. Thus, based on 8 prospective trials, the preventive fraction for early childhood caries is calculated to 33%. Other trials have reported beneficial effects on gum health such as plaque index, bleeding on probing, pocket probing depth, subgingival microbiota, salivary IgA and pro-inflammatory cytokine levels in gingival crevicular fluid. Collectively, current research suggests a role of probiotic supplements as adjunct to the existing “best clinical practice”. No dramatic adverse effects have been reported but the optimal dose, timing and mode of delivery, remains to be established.

Early Intervention for Prevention and Improving Oral Function
The recommended time for a child’s first dental visit should be no later than first year of life. Advances in understanding the factors affecting child development, especially early weeks of infant life suggests that first year dental check up may be too late for some babies. Problems such as breastfeeding, sleep apnea and early childhood caries have huge impact on babies and families. These problems can be managed through counseling, early intervention and working as a team with other health care providers. It is essential that pediatric dentists must be well acquainted with and capable of diagnosing all possible pathologies occurring during this early period of life. In my presentation, I will be talking about early interventions, mostly infant frenectomies and it’s impact on feeding, oral function and prevention of dental disease.

Preventive Orthodontic Treatment
Preventive orthodontic treatment is mainly carried out in the mixed dentition for functional, dental health and psychosocial reasons. Treatment is simple, of short duration and yields the maximum benefit to the patient. In many instances, such treatment can be carried out by the General Dental Practitioner with the supervision of an Orthodontist. This lecture will discuss the various malocclusions that would benefit from preventive (interceptive) orthodontic treatment and the supporting evidence for such treatment. A group of clinical cases where successful preventive orthodontic treatment has been carried out will be illustrated and discussed.

Modulation of osteoclast behavior: Lessons from periodontal disease and tumour microenvironments
Bone-resorbing osteoclasts are multinucleated motile cells derived from haemopoietic stem cells during a multistep differentiation process. Bone marrow-derived osteoblastic stromal cells play an important role in modulating the differentiation of osteoclast progenitors by secreting soluble factors, and through signalling by cell-to-cell contact. This dogma has been now overwritten by numerous supporting cells that contribute several local factors as well as systemic hormones that support proliferation of osteoclast progenitors, differentiation into mature osteoclasts and promote their survival. Though once classified into three categories in terms of the signal transduction: vitamin D receptor-mediated signals [1alpha,25(OH)2D3]; protein kinase A-mediated signals (PTH, PTHrP, PGE2, and IL-1); and gp130-mediated signals (IL-6, IL-11, oncostatin M, and leukaemia inhibitory factor), now the list goes endless as new candidates such as tumour-secreted trophic factors, microbial-derived antigens and some immune cells, such as T-cells have been discovered to influence osteoclastogenesis. Majority of these osteoclast-inducing factors appear to act indirectly by inducing osteoblasts to secrete osteoclast differentiation factor (RANKL), which recognizes osteoclast progenitors and prepares them to differentiate into mature osteoclasts. But studies have shown that direct stimulation of osteoclast progenitors locally by cell-to-cell contact from tumour cells, microbial cell wall derived-antigens, can also trigger differentiation and bone destruction. As for tumour microenvironment, osteoclastic bone resorption promotes release of numerous growth factors (like TGF beta, FGF, IGF, PDGFs) from bone matrix which further stimulate tumour growth ensuing a vicious cycle of mutual dependency. And in the case of periodontal disease, inflammation and bone loss stand as hallmarks. Accumulated evidence demonstrates that periodontal disease involves microbially derived factors and antigens that stimulate local inflammatory reaction and activation of the innate immune system. Proinflammatory molecules and cytokine networks come into play where antigen stimulated lymphocytes (B- and T-cells) take the lead. These novel studies provide undoubtedly new ways to treat several metabolic bone diseases caused by abnormal osteoclast recruitment such as osteoporosis, osteopetrosis, cancer-induced osteolysis, Paget’s disease, rheumatoid arthritis, and periodontal disease.

Preventive planning for long term stability in esthetic implantology
Aesthetics in dentistry as considered to be a dilemma for many reasons. The leading difficulty is that having consensus or evidence based results are as the main results are based on experts experience and patients satisfaction. In this perspective implant restorations on aesthetic area are restored with same principals coming from tooth born restorations. There are numerous modifications to be considered when it is to be an implant restoration. Starting from surgery, peri-implant tissues and prosthetic steps ; all stages are advised to be modified at the treatment planing session.
Implant dentistry has changed trough years of history and following case series will show how these changes reflected in our clinical bases.
Reading patient expectations takes the priority in aesthetic implantology. In order to achieve aesthetics in implantology bone and soft tissues must be considered with same importance as prosthetics. As a result, thinking in 3-D will improve outcomes of the restorations.
Discussion on high – cited recently published papers will be mentioned, as advanced to complex case series of prosthetic restoration will be presented.
