FDI makes global periodontal health a priority over the next three years

FDI is increasing global awareness of periodontal health over the next three years through its Global Periodontal Health Project (GPHP). Proposed in 2015, the implementation of the GPHP was set in motion this this year to prioritize periodontal health at a national level through health promotion and disease prevention, and to integrate oral and periodontal health into policies addressing noncommunicable diseases.

What is periodontal disease?

Periodontal (gum) disease including gingivitis and periodontitis is a plaque biofilm-induced inflammatory condition affecting tooth-supporting tissues and bone, and it is among humanity’s most common diseases affecting up to 90% of the adult population worldwide.

Periodontal disease is also closely associated with noncommunicable diseases as they share common risk factors (unhealthy diet, tobacco use, excessive alcohol consumption). It represents a major global oral disease burden with significant social, economic and health-system impacts.

The roadmap to achieving global periodontal health

Periodontal health is essential to general health and key to securing a person’s quality of life and well-being through their life course. It is imperative that governments engage with Chief Dental Officers and Ministries of Health when developing national disease action plans to ensure an ‘oral health in all’ policy approach.

The GPHP seeks to reduce the burden of periodontal disease by raising awareness of its impact and engaging the public, oral health and other health professionals, educators, and policymakers in promoting periodontal health. Over the course of three years (2017–2019), the project is set to deliver a global awareness campaign (including specialized toolkits for target audiences), a white paper, a policy statement, and symposiums at the FDI World Dental Congress. It is a multi-partner project supported by EMS, GSK and P&G.

Periodontal Bacteria May Delay Conception In Women, Study Suggests.

The Daily Mail (6/13) reports that a new study has found women with Porphyromonas gingivalis, a bacterium associated with periodontal diseases, “take three times longer to get pregnant,” and those with P. gingivalis and signs of periodontitis “take four times longer.”

In a release on EurekAlert (6/11), periodontist and researcher Dr. Susanna Paju, of the University of Helsinki, said, “Our study does not answer the question on possible reasons for infertility but it shows that periodontal bacteria may have a systemic effect even in lower amounts, and even before clear clinical signs of gum disease can be seen.” Dr. Paju added, “More studies are needed to explain the mechanisms behind this association.”

MouthHealthy.org also provides information on gum disease.

Genetic Defects in Tooth Enamel Can Lead to Cavities


Published by CDA Journal: Vol 45, N°4:

Research from the University of Zurich have pinpointed a gene complex that is responsible for the formation of tooth enamel. according to a study published in the weekly journal Science Signaling in February.

Two teams from the Centre of Dental Medicine and the Institute of Molecular Life Sciences used mice with varying mutations of the enamel proteins involved in the so-Wnt signaling pathway. Thanks to this transmission route, human and animal cells respond to external signals and specifically activate selected genes in the cell nucleus. The signaling pathway is essential for embryonal development and plays a pivotal role in development of cancer or physical malformations.

“All mice with mutations in these proteins exhibit teeth with enamel defects,” said Pierfrancesco Pagella, co-author of the study. “Therefore, we demonstrated that there is a direct link between mutations in these proteins and the development of tooth enamel defects.”

The teams discovered that three particular proteins involved in the Wnt signaling pathway aren’t just involved in the development of severe illnesses, but also in the qualitative refinement of highly developed tissue. “If the signal transmission isn’t working properly, the structure of the tooth enamel can change,” said co-author Claudio Cantù.

The hardness and composition of the tooth enamel can affect the progression of cavities. Research revealed that tooth decay isn’t just linked to bacteria, but also the tooth’s resistance, said Thimios Mitsiadis, professor of oral biology at the Center of Dental Medicine. Bacteria and their toxic products can easily penetrate enamel with a less stable structure, which leads to carious lesions even if oral hygiene is maintained, according to the study.

Understanding the molecular-biological connections of tooth enamel development and the impact of mutations that lead to enamel defects opens up new possibilities for the prevention of cavities. “New products that hinder the progress of tooth cavities in the event of defective tooth enamel will enable us to improve the dental health of patients considerably,” Mitsiadis said.

Brains, Teeth May Have Not Co-Evolved

A new study from the George Washington University Center for the Advanced Study of Human Paleobiology suggests that human brains and teeth did not evolve in lockstep and were likely influenced by different ecological and behavioral factors.
This research published in the January issue of Proceedings of the National Academy of Sciences challenges the classically accepted view that reduction of tooth size in hominins is linked with having a larger brain. The reasoning is that the larger brains allowed hominins to start making stone tools, which helped reduce the need for large chewing teeth. But recent studies by other authors found that hominins had larger brains before chewing teeth became smaller, and they made and used stone stools when brains were still quite small, which challenges this relationship.
The new study evaluates this issue by measuring and comparing the rates at which teeth and brains have evolved along the different branches of the human evolutionary tree. Researchers analyzed eight different hominin species, identifying fast-evolving species by comparing differences between groups with those obtained when simulating evolution at a constant rate across all lineages. They found clear differences between tooth evolution and brain evolution.
Considering the classical view that proposes co-evolution, researchers expected to see a close correspondence between species evolving at a fast rate for both traits. The differences they observed indicate that diverse and unrelated factors influenced the evolution of teeth and brains.

Surgeon General Report: E-Cigarette Use Is A “Major Public Health Concern.”

The ADA News (12/8, Manchir) reports that the US Surgeon General said in a report released Dec. 7 that e-cigarette use among youth has been increasing in recent years at an “alarming rate,” and public health professionals, parents, and others must work together to address it. “All Americans need to know that e-cigarettes are dangerous to youth and young adults,” said US Surgeon General Dr. Vivek H. Murthy in a news release about the report. “We need parents, teachers, health care providers and other influencers to help make it clear that e-cigarettes contain harmful chemicals and are not okay for kids to use.”

The surgeon general’s office also in December launched a new, consumer friendly website, E-cigarettes. SurgeonGeneral.gov, aimed at educating parent and adult influencers of young people about e-cigarette use.

New York Post: Oral Health Issues May Indicate “Serious Health” Problems.

The New York Post (12/6, Shea) reports that oral health issues can indicate “serious health issues,” ranging from “digestive troubles to diabetes.” The article discusses what health conditions may be revealed by problems with gums, teeth, saliva, lips, and breath. For example, xerostomia may be an indicator of Sjögren’s syndrome, while red and bleeding gums may be a sign of gum disease or diabetes. In another example, the article reports that halitosis may result from poor oral hygiene practices but could also be a sign of acid reflux.
TIME (12/6) carries a Health.com article that also discusses the association between poor oral health and other health conditions, stating “research suggests that the condition of your gums is connected to a variety of health issues,” such as heart disease. The article stresses the importance of cleaning between teeth every day to remove debris and help prevent plaque buildup.
The Oral Health Topics on ADA.org and MouthHealthy.org provide additional information on xerostomia for dental professionals and for patients. MouthHealthy.org also provides information for patients on gum disease, diabetes and oral health, halitosis, heart disease and oral health, and flossing, including the correct flossing technique.

Study Finds Association Between Poor Oral Health And Heart Disease.

Prevention Magazine (11/2) carries the story first published in Men’s Health reporting that a new study from Finland suggests poor oral health may affect heart health. Researchers examined “the teeth and the arteries of more than 500 people,” finding that those needing a root canal were “nearly three times more likely to have acute coronary syndrome” than “patients with healthy teeth.” Study author Dr. John Liljestrand suggests the bacteria from the tooth infection may spread to other parts of the body, including the heart. Dr. Liljestrand recommends brushing twice a day, flossing daily, and regular dental visits to help reduce the risk of tooth decay.
