Title: Braces for a Better Bottom Line

Time: 09:45-10:30

Arnold J. Malerman

Biography

Dr. Malerman, a 1968 honors graduate of Temple University School of Dentistry, practiced General Dentistry in the United States Air Force from 1968-70.  He then entered the University Of Pennsylvania School Of Dental Medicine where he was certified in Orthodontics in 1972.  Dr. Malerman has been a member of Penn’s faculty for 45 years and is a Clinical Professor of Orthodontics.

Abstract

The role and timing of orthodontics in a comprehensive restorative treatment plan is exquisitely important to the overall success of treatment.  By creating a better platform on which to accomplish restorative treatment, the ease of restorative treatment is enhanced, chair time is reduced, and the result is better treatment for the patient and a better bottom line for the primary care dentist.  Understanding how to better interface with the Orthodontist will dramatically improve care for your patients while at the same time making it easier and more cost effective to provide restorative care.

Course Content

Adult patients with comprehensive complex treatment requirements will be evaluated, treatment planned, and their treatment presented. Emphasis will be placed on the importance of occlusion correction as an adjunct to comprehensive care. The timing of orthodontics in the overall treatment plan for each patient will be evaluated

Course Objectives

To familiarize the participant with comprehensive treatment planning including orthodontic treatment, the benefits of such treatment for both the patient and the dentist, and the sequencing and timing of treatment

Carey O’Rielly

Biography

A graduate of Duke University and USC Dental School, Dr. Carey O’Rielly has been a practicing dentist for 34 years.  He began his career owning and operating a network of six offices in the San Francisco Bay Area.  Later he was a dental director for a California insurance company and monitored care for fifty dental offices.  Presently he owns and operates a private holistic practice in North County San Diego’s Encinitas.

Dr O started looking for solutions to his health challenges resulting from stress and environmental toxicity that built up over a ten year period practicing dentistry.  When he found what he needed to heal from these health challenges, it changed his life and his approach to dentistry.

Dr O’Rielly has dedicated himself to learning about oral systemic infections and how dentistry can affect your health.  Dr O has applied what he has learned to develop specialized protocols that address spirochetal infections in the periodontal tissues and around implants, and a laser protocol for addressing apical periodontitis and root canal infections. He will be discussing these protocols and technology behind them during the meeting.

Abstract

There has been a lot of controversy over the last two decades about root canals and what to do when they become re-infected.  Dentists and endodontists almost always recommend retreatment and saving the tooth.  Conversely, holistic dentists and alternative health practitioners many times land on the side of extraction.  Sometimes, the patient gets caught in the middle and confused by this disagreement in philosophy and treatment approach.  With the release of the movie ‘Root Cause’ there is even more confusion for patients with what to do with root canal teeth.  The premise of the movie is that all root canals are infected and that all root canal teeth should be extracted, because root canals cause systemic disease. 

In this pilot study I will highlight what peer reviewed research says about the incidence of root canal infections, their remediation, and the oral systemic consequences.  I will also present the radiographic incidence of apical periodontitis with existing root canal teeth from patients in my own practice.  As part of this study I will be comparing and contrasting normal PA radiography with Cone Beam images to show different diagnostic capabilities.

Subsequently, in 2018, he has been given the responsibility as the Faculty in charge for the Geriatric Dental clinic. He had been appointed as the External Examiner in various institutes in India for evaluating BDS and MDS students.

Abstract

To find out and to understand the reasons and the associated problems for not

substituting the lost teeth and to make an attempt in reducing the possible cause of not replacing the missing teeth. A total of 300 patients who had visited to the Faculty of Dental Sciences, Sri Ramachandra Medical college & research institute with aged above 25 years with as a minimum of one missing teeth (excluding third molars) not replaced for more than three months and have visited the Institute other than for replacement of the missing teeth were selected. The study includes a predesigned and structured questionnaire containing seven (closed end) questions and followed by clinical examination recording the number and positions of the missing teeth.

All the data were statistically analyzed. Statistical analysis shows the 42% of the patients

find economical reason as the main hurdle for the replacement of the teeth followed by 33% of patients finds lack of time and remaining 25% of the patients are unaware of replacing the missing teeth. The 62% of male patients were found to be not pleased with their existing oral condition in terms of mastication of food & whereas 61% of female patients were found to be not satisfied with the aesthetics of the present dentition. Out of the various reasons, the economic reasons was the key reason for non- replacement of missing teeth. The patients having missing posterior teeth had more than the one-year duration of edentulousness. It can be suggested that, to reduce the economic burden in replacing the missing teeth, the Government of India and the insurance providers can include the dental treatment in their list of treatment covered by the health insurance.

Have undergone extensive training at the M A Rangoowala Centre for Maxillofacial Rehabilitation & The Institute of Maxillofacial Prosthetists & Technologists (UK), Authored one book & 23 publications in various international and national journals.

Abstract

The use of dental implants to restore missing teeth has become increasingly widespread over the past two decades. The successful outcome of any implant procedure requires a series of patient-related and procedure related parameters. Diabetes Mellitus (DM) is the most common systemic disease which is generally considered as a relative and not an absolute contraindication for implant therapy. It is a systemic disease with several major complications affecting both the quality and health of life with a group of metabolic disorders characterized by an increase in plasma glucose levels. Diabetes presents in two forms: insulin-dependent and non-insulin dependent types. In both types, the therapeutic goal focuses on maintaining blood-glucose at normal or nearly normal. Success of a dental implant is detected both clinically and radiographically, which involves measuring clinical parameters including peri-implant loss of gingival attachment, bleeding on probing, suppuration and mobility. Other relevant assessment includes peri-implant radiographic examination and microbiological sampling. The aim of the study is to evaluate the efficacy of dental implant as tooth replacement in diabetic patients with acceptable metabolic control with early non-functional loading protocol evaluated at periodic time interval for three months. Survival of the implants is evaluated by radiographic evaluation to measure the crestal bone heights, clinical assessment by bleeding on probing and microbiological colonization around the implants.

The authors of the article will elaborate on integration of digital dentistry methods in the rehabilitation of patients with the upcoming reorganization of function and aesthetics. Implementing the GNM protocol with the availability of high-quality examination methods in symbiosis with maximum accuracy and speed of implementation, scanning a patient with a facial scanner, the oral cavity with an intraoral scanner. Today, a modern dentist and technician have a great opportunity to digitize the patient completely. Advantages of the Laboratory that has acquired these technologies will be listed and discussed. A dentist having such a technology makes a great impression on the patient, the shape and aesthetics of a smile can be adjusted in the presence of a patient, you can create a future design together, send it to a mobile device. The advantage of an intraoral scanner: after scanning the oral cavity in color, you can display the state of teeth and bite on the large screen, increasing and rotating the scanned jaws.  Another application of the intraoral scanner is the "Smile Bank" where you can offer young people the service to scan their beautiful teeth and save STL files in the cloud, and if necessary even after 20-40 years you can always go back to the dentist with the request to restore the smile of his youth. Other applications and advantages of digital technologies in dentistry will be demonstrated. Patient examination report and a treatment plan in conjunction with modelling stages of rehabilitation will be presented.

Abstract

The modified Palatal Lever Arm System (PLAS) fixes the maxillary first molar via the PLAS from the mid-palatal mini screws. It provides absolute anchorage to molars. In addition, tipping, rotation and any other side effects of the maxillary first molars are prevented. Moreover, it is possible to perform unique orthodontic tooth movements such as expand dental arch to unilateral side individually, which is considered to be difficult using conventional devices.

Case 1

The patient was a 20-years-old Japanese woman. Her chief complaint was crowding of upper teeth. The left molars showed crossbite, and the maxillary left lateral incisor was positioned lingually. The inter-canine Class II relationship was observed. Four first premolars were extracted. By activating the left arm of the PLAS to the buccal side, the left side of the maxillary dental arch was expanded and crossbite of the left molars was corrected. The occlusal cusp-fossa relationship was established in the occlusion with complete Class I canine relationship.

Case 2

The patient was a 25-years-old Japanese woman. Her chief complaint was upper teeth protrusion. The degree of overjet was 11.3 mm. Mandibular left second premolar was positioned lingually. Lateral cephalometric analysis showed a skeletal Class II jaw relationship. Maxillary both first premolars and mandibular left second premolar were extracted. Lingual multi-bracket appliances, mid-palatal miniscrews and modified PLAS were applied. The maxillary incisors were retracted with absolute anchorage of the maxillary both first molars. Proper overjet and overbite were achieved.

Abstract

Backgrounds: Oral Cancer accounts for almost 1/3rd of all the other cancers of the body. It is a major problem in India and ranks among the top three types of cancers in the country. When detected at the early stages of development, it could potentially increase the survival rate.

Late detection of oral cancer is usually seen due to lack of public awareness, scarcity of screening services at the population level and for the working people it is difficult to visit a screening center or to be at home during the day to be screened by a visiting health care worker.

Conducting awareness and screening at the workplaces will surely help in overcoming above challenges and thus in reducing the burden of oral cancer in India.

With this need the present study was designed with an aim of creating oral cancer awareness and screening among the three occupational groups at their work places in Mangaluru Taluk.

Methods It is a Community based cross sectional study carried out in Mangalore Taluk of Karnataka state of south India for a period of 6 months among the various occupational groups like Police personnel, Karnataka state Reserve police, airport staff, health University non teaching employees, Auto-rickshaw drivers, construction workers, city corporation workers and KSRTC bus conductors and drivers. An awareness talk was given followed by oral cancer screening. A total of 3000 people participated in the study. Screening was carried out by oral visual inspection by a trained dental surgeon. Screen positive people underwent counseling and were motivated to quit the habit. They were referred for further investigations and treatment. Descriptive statistics were performed and presented as means and percentages. The association of tobacco related habit with the lesions was found using chi-square tests.

Screening was carried out by oral visual inspection by a trained dental surgeon. Screen positive people were referred to dental hospital for further investigations and treatment.

Results: Out of 3000 people who attended the awareness talk 2011 (67%) participants (1255 males and 756 females) agreed for oral cancer screening. Almost 38% (764) of the screened population had tobacco related habits either smoking or in the smokeless form. Prevalence of tobacco associated oral mucosal and potentially malignant disorders was 8.2% (164 cases). Prevelance of OSMF was 2%, Leukoplakia 1.8%, Tobacco pouch keratosis 2.3%, Chewer’s mucosa 1%, Smoker’s melanosis 0.4%, Smoker’s Palate 0.2%, Pre-leukoplakia 0.2%, Erythroplakia 0.2%, Lichenoid Reaction 0.05 %.

 

The prevalence of tobacco habits were found to be highest among the construction workers 68.3% (24% smoking, 44.3% chewing form), followed by  City corporation workers 63.3 % (7.3% smoking, 56% chewing),  and Conductors and drivers 47.2% (15% smoking, 32.2% chewing). Prevalence of tobacco associated lesions were also found to be more among these three groups were 13%, 7% and 7% respectively whereas the prevalence of Oral potentially malignant lesions were 8%, 4.2% and 18.3% respectively. Correlation of the tobacco chewing habit and the oral lesions were found to be statistically significant.

 

Conclusion: Awareness and screening at the work place is an effective and convenient method for early detection of oral potentially malignant disorders. Creating awareness about the ill effects of tobacco and oral cancer among the various occupational groups may help in decreasing the prevalence of its use and also in reducing the burden of oral cancer in India. More such programs are required to make the health care accessible for the working people.

Title: The Alkaline Dental Cure

Time: 09:45-10:30

Lewis Gross

Biography

Dr. Lewis Gross is the Director of the Tribeca Center for Integrative and Holistic Dentistry. He is a pioneer in offering less invasive alternatives to traditional dentistry for over 39 years and lectures around the world. Dr. Gross recently presented this lecture to the World Dental Congress 2015 in Dalian, China and Copenhagen, Denmark 2017.

Abstract

Background

Recent research by P.D. Marsh on the Ecological Plaque Hypothesis has demonstrated that raising oral pH is a natural cure for dental decay. There are new oral care products that claim to be alkaline mouthwashes. The purpose of this study is to determine if Alka-white Mint is more efficacious than Alka-white Turmeric in alkalinizing the saliva.

Methods

A series of tests by researchers from Holistic-dentists.com, 17 Park Place, NY, New York, were performed on 72 randomly chosen patients to determine the efficacy of Alkalinization of Alka-white Mint (41 patients) vs Turmeric (31 patients). Litmus Reagent test strips by pH Perfect brand (pH 4.5-9) were used before and after rinsing with each product. Researchers asked patients to rinse for 30 seconds with 100mm of warm tap water with one whole tablets of Alka-white Mint or Turmeric dissolved in solution. A record of pH changes was compared to the enclosed pH chart and noted.

Lessons

Researchers discovered that just one 30 seconds rinses with either solution alkalinized the oral cavity, whitened teeth, and freshened breath. Alka-white mouthwash/ toothpaste increased the oral pH Mint 1.26 and Turmeric 1.5 (based on 4.5-9 scale). In all, 92% of Alka-white Mint users and 93.5% of Alka-white Turmeric users claimed their teeth were whiter after using. 97.5% of the Mint and 96.8% of the Turmeric claimed their breath was fresher after use. With these results, researchers need to determine long-term effectiveness of alkaline rinse.

Conclusions

Many patients, especially adults, are seeking alternatives to fluoride, chlorine and alcohol in their dental wellness care.    Salivary acidity is an under-utilized body measurement that can be used by doctors to diagnose oral disease. Normal saliva has a PH of 7.2, but only in a more alkaline environment can teeth remineralize. Increased alkalinity is an important resource in the naturopathic treatment of dental decay.  ALKA-WHITE, created by Dr. Lewis Gross, is a natural mouthwash made from essential oils and spices.

Abstract

Objectives

To evaluate the in vitro growth inhibition of Candida albicans, in the soft?liner material and shore hardness from resin?based denture soft lining materials modified by neem or garlic incorporation.


Materials and Methods

Resin discs were prepared with poly methyl methacrylate (PMMA) and soft liners incorporated with varying concentrations of neem or garlic. For antifungal activity, resin discs were placed on agar plates inoculated with C. albicans and were evaluated after 2, 4, and 7 days using the streaking method. The hardness of the PMMA was evaluated with the use of Shore A at 2, 4, and 7 days. Data were statistically processed by SPSS software (IBM Company, Chicago, USA) using Kruskal–Wallis test, and post hoc comparisons were done using Dunn’s test. P <0.05 was considered statistically significant.


Results

Neem and garlic added to PMMA soft liner had an inhibitory effect on C. albicans. Both the neem and garlic when added showed positive results against C. albicans when compared to the control group. The soft-liner hardness increased statistically by time but not for the different plant extract concentrations.


Conclusions

Within the limitations of this in vitro study, it was found that neem and garlic can be used as an additive to tissue conditioner to reduce the adherence of C. albicans without significantly affecting the hardness of the heat?polymerized acrylic resin.

Abstract

The purpose of this study was to evaluate and compare TiZr15 with other framework materials for an implant supported prostheses by means of a three-dimensional finite element analysis (3D-FEA). A geometric model was constructed with four implants based on the “all on four” concept for a moderate atrophic maxilla supporting a framework of three different materials. Three different materials were selected and their properties were simulated using the FEA software in the generated geometric model. In this study, different framework materials like titanium (Ti), titanium- 15 -zirconium (Ti-15-Zr) and PEKK were evaluated and compared for an implant supported prostheses to analyse the stress distribution on the framework, the four implants and the surrounding structures. The main aim of the study was to find a suitable framework material that could withstand the occlusal load whereby, less stress was placed on the framework itself and also to the implant and surrounding bone suggesting a more favourable stress distribution and a long-term safety of the overall components of the prostheses.

Abstract

Background:

Obturators are an integral part in Post-surgical management of Maxillectomy patients. There are several techniques and materials used for taking impression in the post-surgical phase, but the choice of materials for fabrication of Obturators and the defect portion are Acrylic resins and Soft liners. Poly Vinyl Siloxane (PVS) is one of the best-known accurate impression materials with good short-term Biocompatibility, however its use as a delayed surgical obturator has not been validated till date. There is no literature to substantiate its long-term effects of Biocompatibility. Hence the aim of the study is to evaluate long-term cytotoxicity of polyvinyl siloxane on the Oral cell-line.

Method:

Part 1: Experimental samples of PVS of specified dimensions will be subjected to cytotoxic studies on oral cancer cell-line. The long-term cell viability (14 days) will be evaluated using MTT assay, cell cycle analysis and apoptosis.

Results:  

The results was statistically analyzed by one-way ANOVA test (p <0.05) showing significant decline in the live to dead cell ratio between the test and control group however there was no significant difference between the two groups in the decline of live to dead cell ratio.

Conclusion: The delayed surgical obturator placement is to restore and maintain oral function to a reasonable level during the postoperative period, without causing much discomfort.  So far, PVS is well known for its use as good impression material, but the extended use of it as a DSO (defect portion) is still unexplored and untouched. This original research paper is first of its kind to use PVS as a defect portion of an obturator with scientific evidence.

According to the World Health Organization, about 15% of the world’s population lives with some form of disability. Dental patients will present with chronic medical conditions such as cardiovascular disease, diabetes, Alzheimer’s disease, head and neck cancer, and developmental disabilities such as Autistic Spectrum Disorder and Down syndrome. Dental providers must be prepared to meet the needs of the changing demographics of our patient population.

Melisa Munzenmayer

Biography

Melisa Munzenmayer has her expertise in economic evaluations from a Master of Public Health in The university of Melbourne. Her passion in improving the health and wellbeing from the community began when she worked as a dentist in a Primary Family Health Centre, where she improved her dentistry skills and developed her social skills to give the best attention to who need it more. Actually she works in the Austral University from Chile, where she teaches pre and postgraduate public health courses to all the Faculty of Medicine careers, and also makes investigation related to improve the dental attention of elderly in nursing homes, among others investigation projects where she has been invited. Her cost-effectiveness analysis model is based on the most affordable assumptions from each country where she has worked.

Abstract

Background

One of the principal causes of infection in institutionalized elderly is pneumonia1, which can be reduced by better oral hygiene and regular professional oral health care (POHC) 2. As increasingly cohorts of older adults are entering nursing homes (NH), the need of further development and provision of oral health programs in ageing dentitions is urgent. The objective of this investigation is to conduct a model-based cost-effectiveness analysis, from a health care system perspective, of using oral health professionals to provide oral hygiene services at NHs in Metropolitan Region of Chile, compared to current practice (CP) to prevent pneumonia cases.

Methods

The model was based on 22.044 NH places in the Metropolitan Region over one year. The main outcome measured was ‘cost per pneumonia case averted’. Four different scenarios of oral hygiene provision were compared to CP. Costs included were NHs staff training, professional salaries, program coordinator office expenses, dental equipment, and hospitalization costs. Effectiveness assumptions for each scenario were based on systematic reviews and randomized control trials.

Results

All four scenarios were dominant strategies. The magnitude of negative Incremental Cost-Effectiveness Ratios was not informative; therefore, incremental costs and incremental effectiveness were used to present results. ‘POHC provision once every two weeks and current provision of oral health care the other days’ was the most cost-saving alternative. The most effective alternative was ‘POHC provision once a week and non-POHC provision by trained Nurse aids twice per day the other days’. One-way sensitivity analyses confirmed the robustness of results.

Conclusion

The four scenarios were highly cost-effective compared to CP. These results could be a strong basis to implement new oral health programs in Chilean NHs. As pneumonia case averted is only one of the benefits of providing POHC to institutionalized elderly, the finding of POHC as a cost-saving intervention could be strengthened.

Title: Difference in Root Canal length between Populations

Time: 15:00-15:30

Jean Marie Kayembe

Biography

Jean Marie Kayembe graduated at the University of Kinshasa as a Dental Surgeon. He became Specialist and is now Chairman of the service of Conservative Dentistry and Endodontics at the Dental Medicine Department of the Teaching Hospital of Kinshasa University in the Democratic Republic of Congo. His research focuses on endodontics in the context of African population especially of Bantu (Black African). He is also a visiting teacher at Dental school of the “University des montages” in Cameroon. 

Abstract

Aim

To compare the root canal length of each type of Bantu (black African) teeth with that of Caucasians and Asians.

Methodology

A prospective study based on conventional radiography and the tactile sensation was carried out. We performed 1539 canal measurements on 818 teeth from 720 adult Bantu subjects (18 to 45 years old) who consulted at Kinshasa university clinics from 2014 to 2016. The results obtained were compared with those of the literature. Student's t-test and Turkey tests were used for the statistical analysis of the difference in tooth length.

Results

The average difference with Asians is 0,8 mm more for Bantu versus 0.4 mm less compared to Caucasians. The greatest difference between Bantu and Asians is found in the palatal canal of the upper second molar (3.1 mm), followed by the distal canal of the second lower molar (3.0 mm ),the canal of the second lower premolar (1.8 mm)and palatal canal of the first upper molar (1.7 mm).

The greatest difference between Caucasians and Bantu is found in the mesiolingual canal of the second lower molar (1.9 mm), followed by the upper central incisor (1.7 mm).  

Conclusion

In most cases, the teeth of Caucasians are the longest, followed by those of Bantu and Asians. The palatal canal of the first upper molar, the distal canal of the second lower molar as well as the second lower premolars of Bantu were the longest in all three populations.

Abstract

Preterm birth and low weight product are health problems worldwide, associated with high mortality and morbidity in newborns. About 15 million of premature babies are born every year (1:10) and 1 million die due to its complications. Many survivors face a lifetime of learning, visual and hearing disabilities. Preterm birth is a multifactorial condition where the inflammatory response plays a fundamental role. Proinflammatory cytokines such as IL-1b, IL-1a, and TNF-a have been associated, and they also are involved in Periodontitis, a disease affecting the tooth supporting tissues. There are multiple reports about association between preterm birth and periodontitis, but there is few information about the immune mechanism. Aim: To compare levels of proinflammatory cytokines (IL-1b, IL-1a  and TNF-a) in serum and saliva of pregnant women (26-33.6 weeks of gestation) with and without periodontitis and controls. Methods: This cross sectional study included 60 women, 20 controls, 20 pregnant women with periodontitis and 20 pregnant without periodontitis. Previous informed consent, a medical and periodontal examination was performed. Serum and saliva samples were obtained and the concentration of cytokines was measured by ELISA. Results: It was found that cytokines concentration is higher in pregnant women with periodontitis compared with other groups (p<0.05) and the concentration is similar in saliva an serum (p>0.05). Conclusion: Periodontitis has an effect in the increment of cytokines associated with preterm birth in pregnant women and this increase is reflected both in saliva and serum, therefore saliva could be a noninvasive method to identify the possible risk of periodontitis in pregnant women.
