  • Caries Risk Management: Paradigm of the Third Millennium By: Alexandre Khairallah


    Dental caries (tooth decay) is a major oral health problem in most industrialized countries. The global increase in the prevalence of dental caries has affected all age groups in general, but the younger generation in specific. The only logical explanation for this seems to be the transition in nutrition. The selective consumption of sticky, sugar-containing snacks that are favorites among people and in particular children are directly responsible for the spread of this universal disease. The substantial increase in the prevalence of dental caries is a signal of pending public health crisis that demands specific attention. Nutritional education and counseling of parents regarding the importance of reducing the high-frequency exposure of their kids to obvious and hidden sugars seems to be the foremost step that should be initiated.

    From GOOD to GREAT! By: Shadi S Samawi

    Naturally, this constant stream of technological advancement can seem confusing, even intimidating, to both dental practitioners and their staff. It is important to carefully research and plan any transition to digital technology and allow everyone involved to have sufficient training and time to understand and adapt to the new way of doing things. Our leadership capabilities will be tested and most evident in such situations where we lead our practice and staff into new and exciting territory.

    Implants in the Esthetic Zone; Challenges and Solutions | Part 1 By: Tareq Abu-Saleh, Bashaar Aboushaar


    In the anterior maxilla, esthetic and functional treatment outcomes highly depend on the level of alveolar ridge reconstruction or preservation.

    Insufficiency of alveolar bone may necessitate an augmentation procedure to achieve optimum results. Implant treatment showed high success rates but many challenges are faced. This review presents the challenges associated with implant treatment at anterior maxilla as well as ridge preservation techniques to overcome some of the challenges. It ends with the evidence based knowledge pertinent to this topic.

    Forced Eruption of Impacted Canines with Micro-Implant Anchorage by: Luai Mahaini

    The most challenging problem in the orthodontic practice is the palatally impacted canine and the most commonly used treatment modality is canine alignment and withdrawal to the line of occlusion. However, the duration and prognosis of such treatment is not always predictable. The orthodontic traction may take much longer time than expected and patients may encounter pain more frequently than explained. It has become obvious that all efforts should be made to make canine orthodontic movement more predictable without exerting unnecessary forces onto the neighboring teeth to avoid the well-known side effects to the remainder of the dentition.

    Microscrews are useful aids in these cases. It can be sensibly exploited to assess the prognosis of canine movement, open adequate space for the canine, and build up a reliable anchorage unit that will allow the application of controlled directional forces with fewer side effects on the anchorage teeth. Treatment would be therefore facilitated and shortened.

    The purpose of the current paper is to evaluate the effectiveness of a new method employing mini-implant-anchorage for an orthodontic traction of impacted canines reducing the treatment time without using a complete fixed appliance.

    Oral Pyogenic Granuloma | A Literature Review & Case Report By: Mohammad Assaf

    This paper presents the literature related to etiology, incidence, clinical, and histological appearance of Pyogenic Granuloma. The management of this pathology occurring in the oral cavity is described as well. A case presentation of a thirty-seven years old female who was complaining of the appearance of a tumor on the gingiva related to upper first molar is reported. The benign lesion was excised and pathologically analyzed. All aspects of diagnosis and treatment of the case are presented with a one-year follow up.

    Effect of Immediate and Delayed Finishing and Polishing Procedures on Micro Hardness and Gloss of Esthetic Restorative Materials By: Nazish Fatima

    Objective: To study the immediate and delayed finishing and polishing procedures effects on surface micro hardness and gloss of different composite.

    Materials and methods: The restorative materials included a Hybrid composite (Valux TM Plus), Nano resin composite (Filtek_ Z350) and a poly acid modified resin composite Dyract Extra (Dentsply Caulk, Milford, DE, USA). 30 discs were fabricated from every restorative material and at random divided into three groups. The group one served as control. Group two was finished and polished immediately and the third group was finished and polished after 24 hours. Three Vickers micro hardness indentation were performed on every disc surface under 100g load and 10s dwell time. Gloss measurements were done using a small-area glossmetre. Data for surface micro hardness and gloss were analyzed by two-way ANOVA and Tukey test (P<.05).

    Results: With respect to material wise comparisons the lowest values of micro hardness were observed for every restorative material which was cured under Mylar strip (control). The greatest values of micro hardness were observed when finishing and polishing of samples was delayed (P<0.05). There was not a significant difference in gloss measurements with respect to material and time.

    Conclusion: All three types of composites tested showed highest value of micro hardness when finishing and polishing procedures were delayed for 24 hours. There is no statistical difference in gloss measurements with respect to material and time.
