The British Dental Association stays on top of important trends that affect health. Baby food is the latest research subject in their crosshairs. With infant health a high concern, there is good reason to take a longer look at food consumption. Oral Care Exams Your first infant oral exam at NorthStar Dental Care will go into detail about the dos and don’ts of nutrition. Preventing oral health issues will eliminate some of the most debilitating problems when growing up. This is why the latest research from the BDA is so important, but the devil is still in the details. Before going down the rabbit hole of information, make sure that your baby is scheduled and up to date with all of their dental appointments. The first exam is one of many, with each one after being just as important as the last.

Dentistry has never been more convenient or sought-after than ever before. Not only can dental professionals these days aid with oral health-related issues, but they can also assist with cosmetic dental concerns. Dental veneers are one of the things that can greatly help with a wide array of health or cosmetic dental issues. If you fall into one of the falling categories, you might be a great candidate for dental veneers. Those with Tooth Discoloration dental-veneers-teeth-dentistry-pexel-imageTooth discoloration is such a common issue. It can be caused by improper brushing habits, smoking, or even drinking too many dark beverages like coffee or tea. So, people often opt for teeth whitening as a resolution. Teeth whitening isn’t the only solution for tooth discoloration. Dental veneers, which are little shells that get placed over the teeth, can cover up yellowed teeth or teeth with brown spots quite effortlessly. This way, you won’t have to worry about regularly getting your teeth bleached or purchasing expensive teeth-whitening products.
Unlike whitening treatments that require regular upkeep, veneers offer a long-term approach to achieving a consistently bright smile. Many patients explore professional veneer options, such as those available through cosmetic dental experts like Lowenberg, Lituchy & Kantor, to ensure a natural and durable solution tailored to their specific needs.

MedicalResearch.com Interview with: Scott Thomas, PhD Assistant Research Scientist, Department of Molecular Pathobiology and Fangxi Xu, Junior Research Scientist & Clinical Research Coordinator Department of Molecular Pathobiology NYU College of Dentistry  MedicalResearch.com:  What is the background for this study?  What are the main findings?  vaping-e-cig-smoking-tobaccoResponse: Cigarette smoking is one of the well-established causes of periodontitis, but the effect of using electronic cigarettes (e-cig), especially its long-term impact on periodontal health, is not yet clearly understood. Considering the increased popularity of e-cig use, especially among teenagers and young adults, and the known effect of high nicotine concentration in e-cigarette products, we conducted this clinical research to see if there were differences in periodontal health between e-cig users, traditional smokers, and nonsmokers. The study consisted of two visits, 6 months apart, where measures of oral and periodontal health were obtained. Our data showed significantly greater clinical attachment loss in the e-cigarette users and cigarette smokers than in the non-smokers at both study visits. In only e-cigarette users, we observed an over 0.2 mm average increase in the clinical attachment loss after 6 months.

LaMonte, PhD, MPH Research Professor (epidemiology) Department of Epidemiology and Environmental Health School of Public Health and Health Professions Women’s Health Initiative Northeast Regional Center University at Buffalo – SUNY Buffalo, NY 14214   Dr. LaMonte[/caption] Michael J. LaMonte, PhD, MPH Research Professor (epidemiology) Department of Epidemiology and Environmental Health School of Public Health and Health Professions Women’s Health Initiative Northeast Regional Center University at Buffalo – SUNY Buffalo, NY 14214 MedicalResearch.com:  What is the background for this study?  What are the main findings? Dr. LaMonte:  The rationale for this study was based on existing study results showing
  • (1) oral bacteria are involved with conversion of dietary nitrate (e.g., from leafy greens and beets) to nitric oxide which is a chemical involved keeping arteries healthy and maintaining blood pressure;
  • (2) rinsing the mouth with antiseptic solution (mouthwash) kills oral bacteria and results in rapid increases in systolic and diastolic blood pressure; and
  • (3) a very limited amount of epidemiological data suggest that the oral bacteria found beneath the gums (responsible for gingivitis and periodontal disease) are associated with blood pressure and history of hypertension in middle-aged adults.
Thus, we conducted our study to determine whether oral bacteria (beneath the gums) would be predictive of developing hypertension among women who were without this condition at the time the bacteria were measured. Because the bacteria (exposure) would be known to precede development of hypertension (disease), an association seen in our study would be strongly suggestive of a role for oral bacteria in the development of high blood pressure. Our primary result was for statistically significant higher risks of developing hypertension associated with 10 bacterial species, and significantly lower risks of developing hypertension associated with 5 bacterial species. Our findings were evident even after we accounted for differences in demographic factors, lifestyle factors, and clinical factors, and generally were of consistent magnitudes we examined across subgroups of older and younger women, white and black women, normal weight and overweight/obese women, those with normal or slightly elevated blood pressure at study enrollment, and those who were using or not using menopausal hormone therapy at baseline. Therefore, while our observational study evidence for an association is not equivalent to causation, the robustness of the associations between oral bacteria and hypertension risk supports a need to further understand this relationship, ideally with a clinical trial design that would provide definitive evidence to support or refute causation.

Social isolation is the lack of social contacts and having few people to have regular interactions; while loneliness is the distressing feeling of being alone or separated. Approximately 24% of community-dwelling older adults aged 65 and above are considered to be socially isolated in the United States, and 43% adults aged over 60 years old report feeling lonely. Increasing evidence suggests that social isolation and loneliness are risk factors for older adults’ health outcomes, such as depression, comorbidities, cognitive impairment and dementia, and premature mortality. However, one key limitation in the literature is that only a few studies have examined the impact of social isolation and loneliness on oral health.

Physician-in-chief , Children's Hospital at Montefiore Chair of the Department of Pediatrics Albert Einstein College of Medicine Member, U.S. Preventive Services Task Force  MedicalResearch.com: What is the background for this study and recommendation statement?  Response: Dental caries, also known as cavities or tooth decay, is the most common chronic disease in children in the United States and can develop in any child whose teeth have come in. Many young children under five years old do not visit a dentist, so the Task Force reviewed the latest evidence on how primary care clinicians can help prevent tooth decay in young children. The Task Force’s research led to two important findings: all young children whose teeth have come in should have fluoride varnish applied by their clinician, and all children six months and older whose water supply doesn’t contain enough fluoride should receive fluoride supplements. Both approaches can help prevent cavities in kids. The Task Force also determined that there is not enough evidence to recommend for or against screening for tooth decay in the primary care setting for children under five. This is consistent with the Task Force’s 2014 recommendation on dental caries.

Response: This large study was inspired, in part, by a previous publication, Gustatory Function After Third Molar Extraction (Shafer et al. 1999), which examined the effect of third molar extractions on human taste function.   Their work was based upon more severe extractions and followed patients only up to six months after their surgery. Studies examining taste function over a longer period, i.e., beyond six months from the surgery, were non-existent. The Smell and Taste Center of Penn Medicine, which is the only center of its type in the United States, has a large unique database of patients who have been thoroughly tested for both smell and taste function. This provided us with the opportunity to compare data from hundreds of persons who had previously received third-molar extractions to those who had not received such extractions. Importantly, the extracts had occurred years before thee taste testing.

What is the significance of this oral biofilm?  Response: Dental caries is one of the most common and costly biofilm-dependent diseases that afflict children and adults worldwide. Particularly, Early Childhood Caries (ECC) is a hyper-virulent type of chronic tooth decay that most frequently afflicts underprivileged preschool children. The onset and progression of carious lesions in ECC are rapid and aggressive, causing rampant destruction of the smooth surfaces of teeth. ECC is painful and often requires surgical procedure under general anesthesia, while current treatment modalities are inefficient and recurrence of ECC is common. Notably, interactions between a fungus, Candida albicans, and a bacterium, Streptococcus mutans, have been known to play important roles in the pathogenesis of dental caries. Thus, we attempted to strategically develop a targeted measure to effectively prevent cross-kingdom interactions and subsequent biofilm development.

KAMER, DMD, MS, PhD Associate Professor Periodontology and Implant Dentistry NYU Dentistry MedicalResearch.com: What is the background for this study? Response: The accumulation of amyloid β plaques and neurofibrillary pathology in the brain are pathognomonic to Alzheimer's disease (AD). Brain amyloid deposition begins decades before cognitive dysfunction and is thought to be the first AD pathological feature followed by tau tangle accumulations and other pathologies. The mechanisms by which brain amyloid develops are incompletely understood although inflammation and bacterial imbalances (known as dysbiosis) of the gut and oral cavity may be involved. Periodontal disease affecting more than 50% of elderly is an inflammatory, chronic condition characterized by periodontal tissue destruction and bacterial imbalances. Using PET studies, we showed previously that measures of periodontal destruction were associated with brain amyloid retention in the brain [1]. In this study, we sought to investigate whether subgingival (under the gum line) bacteria associated with Alzheimer’s disease specific pathology, namely amyloidosis and tauopathy.

Response: This study was set out to further our understanding of the link between gum disease and high blood pressure. Recent evidence suggested that individuals with gum disease had a 20-70% increased risk of hypertension and systemic inflammation seemed to be a driver in mediating this association. Further research on the matter was needed. We recruited two relatively large groups of otherwise healthy participants (without a confirmed diagnosis of hypertension) who had gum disease one and healthy gums the other. We found that diagnosis of periodontitis (gum disease) was consistently linked to higher systolic blood pressure independent of other cardiovascular risk factors.

Response: Periodontal disease (PD) affects between 20% and 50% of the global population, with growing evidence supporting its association with other inflammatory diseases, including heart disease, arthritis, and diabetes. Several studies have shown how untreated periodontal disease leads to increased medical care costs for nonoral conditions, including patient hospitalization rates. The interaction of inflammatory diseases with PD suggests a shared, underlying pathology that may be exploited to better manage patients and reduce the economic burden. However, the mechanisms through which these diseases interact are unclear. In periodontal disease, tissue and bone destruction in the mouth is driven by elevated recruitment of white blood cells called polymorphonuclear neutrophils (PMNs), which are activated by the oral disease and recruited from the circulation to sites of inflammation.

While we wait for a vaccine for COVID-19 to be developed, methods to reduce transmission are needed. We chose products that are readily available and often already part of people’s daily routines.

However, how periodontal disease and tooth loss may influence the risk of these cancers has been inconsistent.  MedicalResearch.com: What are the main findings? Response: Our findings support a possible role of oral health in the development of upper GI cancer. Individuals with periodontal disease and tooth loss are at higher risk of developing esophageal and gastric adenocarcinoma. The risk is particularly high for individuals with both periodontal disease and tooth loss.

Constance Wiener, DMD, PhD Associate Professor West Virginia University School of Dentistry MedicalResearch.com: What is the background for this study? Response: Perfluoroalkyl and polyfluoroalkyl substances (PFAS) are chemical groups that have had a wide variety of uses due to their ability to their ability to repel water and stains. They might be found in food packaging, water-repellant clothing and carpeting, paints, fire-fighting foam, and water, for example. Although many are no longer manufactured in the United States, PFAS persist in the environment as they do not readily break down. Adverse health effects have been speculated especially for low birthweight babies, immunological effects, certain cancers and thyroid hormone disruption.1 With these considerations, we hypothesized that there may be an association of PFAS with tooth development and subsequent dental caries (cavities).

What are the main findings? Response: We found chemical-sensing cells in the gums that protect the mouth by standing guard against infections that damage soft tissue and destroy the bone that supports the teeth. With the help of bitter taste receptors that also detect byproducts from harmful bacteria, these special gum cells trigger the immune system to control the amount and type of bacteria in the mouth. This knowledge could one day lead to personalized dental treatments against gum disease. Periodontitis is a serious gum disorder caused by an imbalance in the bacteria and other microorganisms of the mouth. We hope that our new information can help to combat this sixth-most prevalent infectious disease and most common cause of tooth loss worldwide.

Our prior research has found that 80% of prescriptions for dental prophylaxis is unnecessary. Although antibiotic prophylaxis prior to dental procedures is often for a short course (e.g. one time amoxicillin dose), there may be patient harm associated with this.

Response: High blood pressure and periodontitis are highly prevalent conditions that affect more than one third of the adult population worldwide. High blood pressure is the leading global cause of premature death and is the main preventable cause of cardiovascular disease,  while gum disease - also known as periodontitis - leads to severe inflammation of the gums and tooth loss. It impairs aesthetics and function and reduces quality of life. Most importantly, there is increasing evidence that periodontitis increases risk for future cardiovascular disease. Both diseases share common risk factors such as obesity and smoking and are major health problems that significantly impact on health costs.

Light has various applications in human health and normal physiology. Two good examples are vision and sunlight-Vitamin D for bone and health. The use of low dose light to alleviate pain or inflammation and promote tissue healing is termed Photobiomodulation (PBM) Therapy. This treatment can be provided with lasers or LED devices at specific wavelength (color) and dose (power). This treatment is currently being provided by a health care provider - usually a laser - either nurse or dentist prior or during the cancer treatments. There are several exciting innovation where take-home, self-use devices are becoming available.

Reva Senior Researcher, Laboratory of Cellular and Molecular Neurobiology School of Biomedicine, Far Eastern Federal University (FEFU)  MedicalResearch.com: What are the prerequisites for this study?  Response: The existence of congenital and acquired malformations of the teeth and jaws and the many shortcomings of artificial implants dictate the search for alternative methods of treatment of adentia. The prerequisites were the study of the development of the human gastrointestinal tract in the embryonic period, since it is during this period that all the most significant events occur in the structuring of all parts of the gastrointestinal tract, especially the oral cavity, the knowledge of which is necessary for developing a strategy for regenerative medicine. This is associated with obtaining ideas about cell-cell interactions for the cultivation of bioengineering structures of various sections of the gastrointestinal tract, including jaws and teeth. growing-new-teethIt was noted that the differentiation of the structures of the developing jaws is ahead of other divisions. The presence of chromophobic spindle-shaped cells migrating in the direction of the tooth rudiments and their location in the region surrounding the enamel organ indicates intercellular interactions in the development of teeth in humans that differ from these processes in lower vertebrates. At the present stage, it is known that ectomesenchyme is involved in cell assemblies participating in the development of dentin.

Response: Dentists prescribe approximately 1 in every 10 antibiotics in the United States and are the top specialty prescriber. Dentists are the primary prescriber of clindamycin in the U.S., which is associated with a high risk of C. difficile infection (an overgrowth of bacteria in the GI tract that can cause a life-threatening infection). Clinical guidelines recommend that patients with specific cardiac conditions receive a dose of antibiotics prior to undergoing invasive dental procedures to prevent infective endocarditis (an infection of the heart values). Taking a dose of antibiotics prior to a dental visit is referred to as antibiotic prophylaxis. Starting in 2007, these guidelines were narrowed secondary to poor evidence on the effectiveness of antibiotic prophylaxis and the risk of antibiotic-related adverse events. Antibiotic adverse events include antibiotic resistance, C. difficile infection, and other general adverse events (nausea, vomiting, diarrhea). While significant research has been conducted on unnecessary prescribing of antibiotics by medical providers, little work has described appropriateness of prescribing by dentists. We assessed if antibiotics prescribed for prophylaxis prior to dental procedures were consistent with clinical guidelines.

All dentists treat pain worldwide so we would not expect a large difference in which pain medication is prescribed. However, our results show that US dentists prescribe opioids more frequently than is likely needed. This is especially true because studies have shown that non-opioid pain medications are similar or more effective for the treatment of oral pain.

MedicalResearch.com: What is the background for this study? Response: Oral health is an important component of general health and yet dental caries (decay) is still common in children (affecting up to one in three 5-6 year old children in Australia). Although we know that some genetic and lifestyle factors (such as diet) are important risk factors for caries, the relative importance of these is still unclear.  Risk factors from pregnancy and very early childhood (even before teeth appear) might also be important. This study is the first to include prospectively measured data on health and well-being from pregnancy, birth and early childhood in a study of twin children. We analysed data from a cohort of 172 pairs of twin children to assess the effects of genes and environment on susceptibility to dental caries at six years-of-age.

MedicalResearch.com Interview with: [caption id="attachment_48243" align="alignleft" width="189"]Dr. Julie Palmer Dr. Palmer[/caption] Julie R. Palmer, ScD Professor, Boston University School of Medicine Associate Director, Slone Epidemiology Center at Boston University Boston, MA 02118  MedicalResearch.com: What is the background for this study? What are the main findings? Response: Since 1995, 59,000 African American women from all regions of the U.S. have participated in a Boston University research study of the health of Black women.  Study participants complete mailed or online questionnaires every two years. Our major goal is to identify modifiable risk factors for cancers and nonmalignant conditions that disproportionately affect African Americans (e.g., pancreatic cancer, early-onset breast cancer, type 2 diabetes, uterine fibroids).  The reasons for the higher incidence of pancreatic cancer in African Americans relative to non-Hispanic White women in the U.S. are unknown. I was aware that several recent studies in predominantly White populations had observed a higher incidence of pancreatic cancer in those who had reported poor oral health and wondered whether the higher prevalence of poor oral health among African Americans could play a role in their higher incidence of pancreatic cancer.  We had already asked about gum disease, periodontal disease, and adult tooth loss in several rounds of data collection. After rigorous analysis, we found that women who reported any adult tooth loss had about two times the risk of future development of pancreatic cancer compared with those who had no tooth loss and had never reported periodontal disease. The estimated risk was even greater for those who had lost five or more teeth. A similar association was observed for reports of periodontal disease, but the association was not statistically significant.
