Keynote: A Healthy Mouth For Healthy Life
Biography:
Abstract:
The human mouth is home to millions of microorganisms, most of them harmless. Under certain conditions, however, some can cause oral infections such as tooth decay or gum disease. Oral bacteria may also enter the bloodstream if normal protective barriers in the mouth are breached. This can happen as a result of dental treatment or even tooth brushing and flossing. Recent studies point to associations between oral infections, primarily gum infections and diabetes; heart disease; stroke; and preterm, low-weight births. Research is underway to determine if the associations are causal or coincidental. Gum infections have been called "the sixth complication of diabetes," because people with diabetes are more likely to have periodontal disease. Researchers are exploring a possible two-way connection between the conditions to see if treating gum disease improves diabetic control. Recent studies point to an increased risk of heart disease and stroke in people with gum infections; the risk increases with the severity of the oral infection by integrating oral health into strategies for promoting general health and by assessing oral needs in sociodental ways, health planners can greatly enhance both general and oral health. The key concept underlying future oral health strategies is integration with this approach, a major benefit being the focus on improving health conditions in general for the whole population and for groups at high risk, thereby reducing social inequities.

Abstract:
Introduction: The resin cement is recommended to cement the implant fixed prosthesis. Efforts to remove the excess cement protruding after seating restoration, an entrapment of residual cement in the peri-implant tissues can be detected.
Objective: The aim of this study was to detect the retained excess resin cement around tissue level and bone level dental implants following two different cementation techniques.
Materials & Methods: Fourteen tissue level implants (group A) and fourteen bone level implants (group B), (OCO Biomedical, Inc. Albuquerque, USA) were screwed in a drilled models (Salvin Dental Specialties, Inc. Charlotte, USA) having a rubber surface covering, simulating the gingiva. Twenty-eight metal copings were fabricated and were cemented to the implant’s abutments by RelyX U200 dual-cure resin cement. Each group was further sub-divided according to the cementation technique into two subgroups (n=7): sub-group A1, B1: Tack cure of the excess cement for three seconds and the excess partially set resin cement was carefully removed before complete cure. And subgroup A2, B2: 1mm occlusal vent was performed on the occlusal surface of the metal copings. Excess cement from the vent and the margins were carefully removed followed by a full cure. The rubber coverage on the models was removed and any retained cement was collected and the net weight was determined. All specimens were visually examined from all sides under 30X magnification using Stereomicroscope (SZ-11, Olympus, Japan).
Results: The tissue level implant following the tack cure protocol had less retained excess cement percentage than the occlusal vent protocol. Statistically, the comparison showed a significant difference in the retained excess cement percentage within the tissue level subgroups (p=0.018), no statistically significant difference was observed within the bone level sub-groups techniques (p=0.096). There was the statistically significant difference between non-vented tack cure and occlusal vent techniques regardless of the implant type (P=0.004), with more retained excess cement percentage with the vent technique. No statistically significant difference between tissue level and bone level implants regardless of the cementation technique, with more, retained excess cement percentage in the bone level implants. Our result also showed a complete seat of the prosthetic core on the abutments with 1 mm vent hole that sealed the margins properly. Again stereomicroscope showed seepage of the cement around the micro thread at the bone level implants.
Conclusions: Tack curing of excess resin cement during the cementation of implant-supported restorations might reduce the cement residue, but still couldn’t remove the problems of excess resin cement around dental implants. Implants inserted at the bone level might need extra precautions to avoid the problem of retained excess cement that may affect implant.

Title: Prevalence of periodontal disease in institutionalized patients with mental disorders
Biography:
Abstract:
Aim or purpose: The accumulation of bacterial biofilm in the dental plaque structure predisposes the individual to periodontal diseases (PD) (LOE et. al.,1986). PD, on the other hand, has been associated with the pathogenesis of systemic diseases such as pneumonia, cardiopathy, diabetes, among others (KINANE & BOUCHARD, 2008). Individuals with special needs are at particular risk for these systemic diseases (ANDERS & DAVIS, 2010). The Santa Luzia Association houses 107 patients with multiple disabilities. As they did not receive daily oral hygiene, the findings of this study allowed the evaluation of the manifestation of PD in its natural evolution in a population at risk.
Materials and methods: This research was approved according to the opinion of the ethics committee 1,868,206. The epidemiological survey diagnosed PD evaluating probing depth and clinical attachment level (CAL) in 6 sites per tooth. Searches were carried out in the medical records to identify pathologies, comorbidities, use of medications and a degree of autonomy through the criterion of Braden (BERGSTROM & BRADEN, 2002) used by the nursing team. The software Prism 5 (GraphPad Software Inc., La Jolla, CA, USA) was used for statistical analysis.
Results: Neurodegenerative diseases such as Parkinson's and Alzheimer's were associated with severity of PD. Co-morbidities such as diabetes and hypertension were associated with higher probing depth and CAL means.
Conclusions: Clinical studies are needed to establish the biological plausibility of the association between neurodegenerative diseases and PD.

Abstract:
Replacement of lost teeth with dental implant (DI) has become a quite popular alternative from past few decades as it can accomplish both functional and esthetic demands. Amidst many other factors, primary and long-term stability play a vital role in the immediate and long-term success of DI, which further decided by quality and quantity of the native bone next to the DI. The current study aims at estimating the Cortico-Cancellous Ratio (CCR) of the bone surrounding the DI and its association with the primary and long-term stability of the same. Cone beam computed tomography (CBCT) records of 140 DIs, placed at the level of the crest of the alveolar bone were analyzed immediately after placing. Both mandibular and maxillary DI sites were analyzed. CCR was measured at four specific points circumferentially around the implant, means were noted. Primary stability values were evaluated using insertion torque (IT) and implant stability quotient (ISQ) values; long-term stability was measured using only ISQ values after four months for the mandible, six months for maxilla and after two years for both arches. Statistical analysis was done. Results shows significantly higher mean IT and ISQ values with higher CCR. Secondary stability, though significantly not affected, mean ISQ values were improved with higher CCR. Mandibular implants showed higher primary stability values compared to maxillary. Astonishingly, at long-term follow-up, no significant difference was observed between maxillary and mandibular DI’s mean ISQ values. Within the limitations, this study concludes, primary stability may directly associate to CCR. However, long-term stability may not significantly link with CCR.

Title: Implementing perinatal and infant oral health care program in private practice- 10 year experience in private hospital in Shanghai
Biography:
Abstract:
The American Academy of Pediatric Dentistry (AAPD) recognizes infant oral health care as a foundation for offering preventive education and dental care that can enhance the opportunity for a lifetime free from preventable oral diseases. This presentation seeks to provide practical, everyday solutions to implement infant oral health care program in private practice. Aim of implementing the perinatal and infant health in every dental practice is to reduce prevalence of oral disease in pregnant women and infants, increase preventive care and most importantly establish a dental home for infants by age 1. Presentation is based on the best evidence available at this time and provides strategies to implement the program in a busy private practice. Among the different strategies implemented was the care coordination among ObGyn, pediatrician and dentist. Dental check is advised as part of every well baby check. All this is done taking care of various cultural issues as we serve both local and expat community in Shanghai.

Abstract:
The purpose of this presentation is to carefully analyze the findings to date regarding a potential link between periodontitis and carcinogenesis; evaluate, critically review and explore the variety of potential study confounders and study criteria differences which suppress the accuracy and validity of the relationship claims being made; gain an appreciation of the biological plausibility of mechanisms which could be under pinning the relationship between the two diseases; and finally to conclude whether the current level, findings and quality of research is accurate in supporting the existence of the periodontitis cancer link. I will assess the potential link between periodontitis and several cancerous tumor types, and analyze the evidence regarding the biological plausibility for the potential association between periodontitis and cancer. The strongest association is present between periodontitis and oral cancer since each of the three studies looked into show a statistical link between both diseases. The international burden of cancer has risen every year, a trend that has been paralleled by the increase in periodontitis cases. Research undertaken by GLOBOCAN (2012) states there were7.6 million global cancer cases in 2008, and in 2012 there were14.1 million global cancer cases, an increase of 84%. Although there is a lack of recent statistical data related to periodontitis cases, between the years 1997 and 2005, there was an increase of 27% of adults aged between 35 and 44 who had Periodontal pocket depths greater or equal to 4 millimeters (Dye, 2012).

Title: Preventive Dentistry in Pediatric Dentistry a new perspective based on recolonization
Biography:
Abstract:
World preventive dentistry has changed its approach, the emergence of new angles with respect to the etiology of the carious process as well as its dynamism has promoted that simply the effectiveness of treatments has been increasing thus improving the prevention schemes and individualizing them generating a more specific preventive dentistry. Studies show that Fluoride by itself, the inclusion of calcium in the chlorhexidine, the toothpaste, none can be effective by itself if not analyzed each case in an integral way every day is recommended more the use of products that generate an ion exchange between the biofilm and the dental materials causing a beneficial interaction for the host, likewise we enter the era of bacterial disruption and recolonization to promote a better biofilm that is compatible with the oral life of our patient. The recolonization of Biofilm is carried out based on oral probiotics, we know that probiotics are "living microorganisms which when administered in an adequate amount provide a benefit to the host", there are probiotics that are most suitable for the oral cavity and they are the basis for current prevention and the integral approach to which we refer.

Title: Laser as an adjunct in the treatment of peri-implantitis
Biography:
Abstract:
The peri-implant diseases bear great resemblance to periodontal diseases, from anatomopathological features, microbiological profiles, and immunological susceptibility to the forms of treatment. Despite the rational sharing of therapeutic bases, the effectiveness of procedures for decontamination of implant surfaces is considered a critical factor for the success of peri-implant disease therapy. Both the spiral-shaped macrostructure and the irregular microstructure of the titanium surface, promoted by the surface-blasting treatments, make the implant more favorable to adhesion and retention of plaque when exposed. Root scaling and straightening (RAR), considered gold standard due to its predictability in the resolution of periodontal disease, has limited efficacy in the treatment of peri-implant disease when bacterial biofilms reach the implants' spines. Different methods have been proposed to support RAR in order to eliminate bacterial colonies on the titanium surface, helping to eliminate the peri-implant pocket. Detoxification by high-resolution laser has been used in the treatment of peri-implantitis with promising results in the decontamination of the implant surface, as well as aiding the inflammatory response through biomodulating action. The interaction of the laser with the peri-implant surface results in the removal of possible bacterial calcified deposits besides allowing re-osseointegration in regenerative therapy. Laser-assisted regenerative or anti-inflammatory therapies have shown better results in the treatment of peri-implantitis compared to RAR alone and further studies are needed to confirm the scientific evidence.
