The use of zirconia as a restorative material has been increasing day by day. Like any new restorative material we are using zirconia indiscriminately, without understanding it’s composition, properties and behavior. Through this oral presentation an attempt will be made to make the audience understand the composition and properties of zirconia. The different types of zirconia nd the differences between them will also be discussed. An attempt will be made to make the audience aware of how different types of zirconia behave differently. This will be followed by an evidence based analysis of the properties of zirconia that affect long term clinical success. Finally the speaker will also make reccomendations based on evidence to make intelligent treatment decisions. A rubric for planning zirconia restorations will be shared. Handling of zirconia restorations in a correct way will also be demonstrated. The lecture will try to give a complete clinical summary of zirconia froma scientific and educational perspective.

Lasers were introduced into dentistry more than 4 decades ago. Since that time, different wavelengths have been used for oral soft tissue dental procedures. The dental laser can provide clean incision of tissues, immediate coagulation and minimal postoperative pain and edema. A diode laser is a semiconductor device using aluminum, gallium, arsenide and occasionally indium as the active medium. The pump source is an electrical current; the photons are produced by an electric current. The device produces coherent radiation (in which the waves are all at the same frequency and phase) in the visible or infrared spectrum with wavelengths ranging from 810 nm to 980 nm. Therefore, all wavelengths are absorbed properly by pigmented tissue, which contains melanin and hemoglobin. However, they are poorly absorbed by calcified tissue such as hydroxyapatite and water present in the enamel. The diode laser-tissue interaction makes it considerably safe and well-indicated for soft oral tissue surgeries in regions near the dental structures. The diode laser devices have specifications such as relatively small size, portability and lower costs that attract the dental practitioners and oral surgeons to their use in various surgical indications in comparison with other laser equipment. In this presentation, we present a case series of oral soft tissue surgeries (such as frenectomy, pyogenic granuloma, irritational fibroma and mucocele) performed with a 940 nm diode laser with minimal postoperative complications. All cases were performed in oral medicine clinic by two consultants of oral medicine. Written informed consent was obtained from the patients prior to the surgery and all protective precautions were taken throughout the procedures. Different settings of the device were used according to the specific procedures. Postoperative instructions were given to all patients. All patients have been followed up regularly to ensure complete healing. The uses of a 940 nm diode laser in these presented cases offered the best treatment option to reduce the risk of postoperative infection and pain with rapid healing.

Since the high prevalence, worldwide, of periodontitis and periimplantitis, both proven to contribute and/or exacerbate systemic diseases by their inflammatory response, they are becoming a major concern in general health care. The search for finding a cost-effective and repeatable treatment for the majority of the population, without causing detrimental side effects, is a necessity and has been a question mark for many years. Since traditional treatment protocols cannot meet to all our expectations and have some contraindications, the rational of One Stage Full Mouth Disinfection (OFMD) has been the new paradigm in treatment strategy. However, a number of important details can be optimized. Lasers have taken an eminent place in periodontal care in the last two decades. The use of Free Running Pulsed (FRP) Lasers in particular, might solve some shortcomings in the traditional approach. The reason behind this is the way FRP lasers, by their very short bursts of energy, cannot only take care of bacterial and viral components of the periodontal infection, in hard as well as in soft tissue, but also by dissipation of that energy, have the capability to contribute to repair and at certain level regeneration. This can contribute to preservation of soft and hard tissue, in a cost-effective way. 53 patients having dpsi3+ or 4, undergoing all the same protocol of a true OFMD of scaling with adjunct of FRP laser treatment, with or without antibacterial support as indicated along microbiological assessment. Periodontal parameters were compared to baseline, at 2, 8 up to 14 months, without retreatment. Clinical outcome of the parameters for all cases were statistically significant improved to baseline.

Maryam Alfarhan has completed her graduation from Faculty of Dental and Oral Surgery – King Saud University, Riyadh 1986, and received Dental Public Health Master’s degree in 1995 from University of London. Currently, she is Consultant of Dental Public Health and was appointed as Director, Oral Health Services program since 2007. During that period of time she developed oral health promotion programs as part of community dental service in the National Guard of Saudi Arabia. She worked extensively in the area of oral health promotion school based programs, and currently works on voluntary basis in the position of Executive Group Member of the Oral Health Working Group of the WFPHA. In 2017, she is awarded with the title of Diplomat of the Global Charter of the year 2017.
As Dental Public Health consultant my perspective was to study the needs of our community and address it through effective and efficient oral health care strategies. Saudi Arabia has the following socioeconomic indicators: GDP annual growth was four and GDP per capita, PPP, was $22713. Nearly all the country with sustainable access to improved water source and sustainable to improved sanitation. There are 2.3 dentist rates per 10000 populations. In 2004 it was reported in a sample size 12,200 of primary, intermediate and secondary students the caries prevalence was in primary teeth 74-90% and in permanent teeth 59-80%. Behaviour strategies were adopted to develop the organizational effectiveness for School Based dental Preventive Program in the Saudi National Guard primary schools in Riyadh. This strategy affects the people development, inspiration, participatory decision making, and efficient communication. The program objectives was to increase oral health awareness among school children as prime target, inform about importance of diet, provide regular examination in order to make repairs in earliest stages of diseases or decay and seal fully erupting molars of school children in primary schools. The mobile dental clinics were used in this program to provide dental care. Oral diseases are neglected epidemic tooth decay although it affects 60-90% of school aged children and nearly 100% of adults and seniors. The purpose of this policy and program is to encourage government, ministers of health, health departments, and health personal to initiate, implement, promote and support effective population-base dental prevention programs. Dental public health in Saudi Arabia facing many challenges, there is a need for well integrated dental public health systems which include acceptable guide lines and criteria, institutional, reflect population needs at same time cost-effective. There is a strong need to establish national dental public health association focusing on application of a board range of evidence-based approaches and interventions. Effective programs and policies in dental public health through scientific reasoning, including systematic uses of data and information systems and appropriate use of behavioural science theory and program planning. Women in Saudi Arabia will have potential role as leaders in dental public health like: leadership training for all high potentials, shedding biases regarding women in leaderships and thinking and behaving in new ways.

Infection of the oral cavity is an infection caused by the activity of pathological microorganisms such as Staphylococcus aureus bacteria. The use of herbal ingredients such as betel leaf extract, in the assumption, can be useful for inhibiting the growth of Staphylococcus aureus in the infection. This study aims to determine the effectiveness of antibacterial piper betel leaf extract 25% against the growth of Staphylococcus aureus. This research used posttest only control group design, composed of 27 samples of Staphylococcus aureus type A bacteria which were divided into 3 treatment groups, consists of : group I treated with 25% betel leaf extract, group II treated with lemongrass extract 25% and control group treated with Amoxicillin 500 mg. Result obtained by means parametric statistic test, that is one way-ANOVA, obtained p value 0.001 (p<0.05), so there is a significant difference in the inhibition zone of the three groups. Result of Post Hoc Test, that is Least Significant Difference (LSD) obtained p value 0.001 (p<0.05), there is significant difference in the measurement of inhibition zone between groups. Piper betel leaf extract is 25% more effective than lemongrass extract 25% and amoxicillin 500 mg against the growth of Staphylococcus aureus.

Background: Achievement of adequate fit of Co-Cr (cobalt-chromium) frameworks is an important requirement in PRDP (partial removable dental prostheses) treatment for which current evidence on the clinical factors influencing such fit is insufficient.
Objectives: The purpose of this investigation was to retrospectively evaluate the influence of major connector design, and numbers of guide plates and occlusal/incisal rests on the number of fabricated frameworks needed until the realization of clinically adequate fit of PRDP Co-Cr frameworks.
Materials & Method: Electronic case records of 100 partially dentate patients treated with Co-Cr PRDPs in single or both arches, by undergraduate dental students, were examined, and relevant data recorded by three examiners. The relationship between the three PRDP design features with the number of frameworks that were required to be made in each case were statistically analysed by analysis of variance (ANOVA) and Post hoc Tukey tests (α=0.05).
Results: Data were derived from 128 (53 maxillary and 75 mandibular) records of the treated partially edentulous arches. The major connector design, and numbers of guide plates and of rests were found not to be significantly correlated with the number of framework fabrication attempts, for both the arches combined, or when arches were considered independently (P>0.05).
Conclusions: In the present sample none of the component features of PRDP frameworks that were tested were associated with the fit of the frameworks, which suggests that other variables in the fabrication process of PRDP frameworks need investigating in relation to their accuracy of fit.
Clinical Significance: The design variations of Co-Cr partial denture frameworks do not affect the clinical fit acceptability.

Aim: A multi-surface novel power toothbrush had already marketed in China, the aim of the study was to evaluate the toothbrush in clinic to test the plaque removal efficiency on different areas of the dentition.
Methods: A split-mouth design, examiner-blind and single center study was executed. University students were instructed by staff and then brushed their teeth with novel multi-surface power toothbrushes and oscillating-rotating power toothbrushes (as the control group). Before cleaning, all the teeth of the students were colored, then started to be brushed. The total cleaning time in half mouth was 60s, and time points for taking photos for the study were 0s, 15s, 30s, 45s and 60s for the experiment group, and 0s, 30s and 60s for the control group. Rustogi Modification of the Navy Plaque Index and Image Pro-Plus software were adopted to score the plaque.
Results: Multi-surface power toothbrush was more effective in removing plaque in lingual, gingival marginal, buccal and approximal areas. Reduction rates of using multi-surface toothbrush for 30s were 54.94%, 62.34% and 56.47% in lingual, buccal and whole mouth respectively, which doubled the efficiency of oscillating-rotating mode. Using multi-surface toothbrush for 15 seconds shared a similar plaque removal efficiency with using oscillating-rotating mode for 60s.
Conclusions: Multi-surface power toothbrushes could improve the plaque removal efficiency in hard-to-clean areas and considerably shorten the time of brushing.

When teeth become discoloured, especially when they become darker, there is a lot of time and money that is invested into improving the color of our teeth. The way our teeth look is of great importance to many people. Majority of us think that our smile is not white enough to be called as attractive smile. Although an attractive smile may be perceived by some as not a big issue, studies have confirmed that a whiter smile plays an important role in perceived self-esteem and success. In this systemic review lecture I go through an update of what dentistry reach in 2018 to make teeth whiter.

Background & Aim: Child abuse and neglect is a very serious problem that has long consequences for those involved and for society in general. Dental professionals are in an exceptional position to identify and report these cases. Statistics of previous studies revealed that only one percent of dentists reported suspected cases. Aims of lecture are to help dentists to learn about their ethical responsibilities and legal obligation toward child abuse cases and how to detect and report them.
Methods: This lecture will demonstrate types and consequences of child abuse and neglect and the prevalence worldwide. In addition, ethical and legal concerns of different health care organizations related to dentists’ reporting suspected cases. Oral symptoms of child abuse and neglect will be discussed and classified according to the type such as physical abuse, sexual abuse and neglect. Physical abuse may result lacerations of tongue, oral mucosa, palate, gingiva alveolar mucosa or frenum, fractured, displaced or avulsed teeth facial bone and jaw fractures, burns or other injuries. Sexual abuse may represents significant oral manifestations as oral and perioral gonorrhea, unexplained erythema or petechiae of the palate, particularly at the junction of the hard and soft palate, pseudomembranous and condylomatous lesions of lips, tongue, palate and nose-pharynx. Dental neglect is detected by untreated early childhood caries, odontogenic infection or pain, periodontal disease.
Conclusion: Child abuse and neglect can be prevented by increase in Dentist’s awareness about their roles of reporting these cases and strengthen their abilities to detect them in early stage.

Title: The role of Dangke (local dairy product in indonesia) as a cariostatic diet in reducing Streptococcal numbers in dental plaque
Time : 16:00 Pm - 16:30 Pm
Ridhayani Hatta has completed her Bachelor’s from Hasanuddin University, Indonesia. Currently, she is pursuing her Master’s at School of Clinical Dentistry, The University of Sheffield. She is a General Practitioner in Makassar, South Sulawesi and a young Resercher in Hasanuddin University, Indonesia.
Objective: Dairy products were proven to prevent caries because their cariostatic properties inhibit the attachment of cariogenic bacteria such as Streptococcus that accumulates on dental plaque. Dangke is a typical dairy product from Enrekang, South Sulawesi and Indonesia which is traditionally processed and derived from cow's milk coagulation using coagulant from sap of papaya (papain enzyme). Dangke with high protein content that reached 17.20% is considered to be one of non-cariogenic food. The aim of this study was to asses the role of Dangke to reduce Streptococcal numbers in dental plaque.
Design & Methods: This study was a quasi experimental study with post-test including only control group design. It was performed in 15 subjects who met the inclusion criteria with simple random sampling method. The study group consisted of Dangke as treatment group and chadder cheese as control group. The plaque samples were taken twice in each group: directly after (T1) and two hours after the consumption of dairy products (T2), thus obtained 30 samples of plaque in each group. Evaluation of the amount of Streptococcus was done in the Microbiology Laboratory, Faculty of Medicine, Hasanuddin University.
Results: The mean colonies of Streptococcus in Dangke and cheddar cheese group on T1 were 19.44, 31.56 CFU/ml respectively, and T2 were 2.44, 27.56 CFU/ml respectively, with p-value in Dangke group was p=0.028 while in cheddar cheese group was p=0.746.
Conclusion: Dangke was effective to reduce Streptococcal numbers in dental plaque.
