How PH ranks in dental health

MANILA -- The Philippines has nine million denture wearers in urban areas, making it the country with the highest number of people wearing dentures in Asia, according to a study by an international pharmaceutical company.

The information was revealed in the study "Oral Care U&A: Market Understanding Study Middle East & Asia" conducted by Ipsos Marketing for GlaxoSmithKline (GSK).

Based on the study, majority of the nine million denture wearers are in the 35 to 69 year old age group. Eighty-four percent of denture wearers reside in Metro Manila, with nine percent in Cebu, and six percent in Davao.

Another study, "The Emerging Consumer Denture Journey" by Nick Newall and Rachel Kern also outlined the causes for such spike in denture wearing, among them the limited access to oral hygiene, expensive dentist fees, and lack of awareness of importance of oral hygiene and its effects to self-confidence.

The study also showed that Filipinos' oral and dental health care practices are very limited.

"The Filipinos' oral and dental health care practices are limited to very simple routines like brushing the teeth using regular toothpastes and toothbrushes. Some even use alternative household products such as salt water for cleaning the teeth," cited the study.

The study also discussed the fact that in the Philippines, dentists are rarely a source of awareness in terms of oral care. It reported that there is a forced relationship between dentists and patients who meet only during emergency cases. Some people, according to the study, even have others pull their teeth off.

However, the most damaging of these is the loss of practice of revisiting the dentist for follow-ups.

"We must create value for our teeth regardless of financial difficulties. In terms of dental relationships, people neglect returning to their dentists for maintenance purposes, doing so only when the damage has been too great to bear," said Dr. Danny Magtanong of the Philippine Prosthodontic Society (PPS).

Magtanong, who specializes in reconstructive dentistry and is an associate professor in prosthodontics at the UP College of Dentistry, also explained that Filipinos have become apathetic toward their teeth.

"Not only is the "bahala na" attitude of Filipinos alarming, but also the lack of value for teeth. For example, people in the past would have attitudes like "okay lang 'yan, masisira din naman ngipin mo," these attitudes have evolved to be damaging towards the total dental health of the individual. So now, many become more and more subject to dental problems not only because of this attitude, but also largely due to Filipinos' inadequacy to acquire proper dental health implements. What Filipinos largely know of is only to brush their teeth; on some occasions, gargle with salt if financial circumstances are not favorable."

PPS, in coordination with GSK, has been undertaking an education and information campaign both in urban and rural areas to promote dental health and proper denture care.

Why 'silver pasta' isn't toxic

MANILA -- Dental amalgam, or "silver pasta," is not toxic despite containing mercury, a University of the Philippines professor and dentist said on Wednesday.

In an interview with Nina Corpuz on dzMM's "Magandang Gabi Dok", Dr. Michelle Segara, faculty member and chairman of the Department of Basic Dental Health Sciences of the University of The Philippines (UP) College of Dentistry, said dental amalgam is not dangerous to health and shouldn't be banned.

"Walang scientific evidence directly connecting dental amalgam sa mga diseases na sinasabi nila, like pagkasira ng utak, Parkinson's disease, Alzheimer's disease," Segara said.

Clamor rose for the banning of "silver pasta" after an environmental group released a study saying that mercury levels in the air in dental schools in the country are dangerously high.

Segara, however, said sweeping generalization is dangerous. She added that one study alone cannot prove that dental amalgam is toxic and should be banned.

She said that dental amalgam has been in use for more than 150 years, and experts haven't found any direct link between the mercury found in the amalgam and any diseases or death.

"We concur with other agencies in Europe and in the US. Even the World Health Organization (WHO), in their Minamata Convention of 2013, exempted dental amalgams and vaccines in their ban on mercury," she said.

She was referring to the Minamata Convention of 2013, wherein different countries pushed for the total ban on mercury following the large-scale public health crises caused by mercury poisoning and Minamata disease in Japan and in other countries.

What's in 'silver pasta'
Segarra explained how mercury is used in dental amalgams.

"Masama ang mercury, pero kapag ginamit mo siya sa dental fillings, like silver pasta, the mercury is bound to the silver so hindi siya makakalabas."

The mercury inside the amalgam can only be toxic if it leaches.

However, she explained that even in that case, it will have minimal effects as only a minute amount of mercury is used in dental amalgams.

She added that the kind of mercury used in dental amalgams is organic mercury, which is relatively safer compared to methyl mercury being used in industries that causes the Minamata disease.

She also said that the UP College of Dentistry, as well as other dental schools in the country, practice good mercury hygiene by ensuring that dental amalgams are not left in room temperature to minimize mercury emissions.

"Mercury vaporizes in room temperature. If the temperature is below 27 degrees, then there will be mercury emission."

No need to panic

Segarra advised people not to panic and go to their dentists to have their "silver pasta" removed, saying that it is actually more dangerous than leaving it on the teeth.

"Kapag dini-drill out yung amalgam, mas may emission kasi umiit siya. Mas toxic kapag ganoon."

She also explained that it is considered unethical for a dentist to remove a sound dental filling.

A damaged dental filling, on the other hand, is a different story.

Segarra added that there are certain safety precautions that a dentist should practice in amalgam extraction, like putting a rubber dam on the patient's mouth to separate the amalgam from the mouth, and using copious amount of water while extracting the amalgam.

She said minimal mercury vapor is emitted during amalgam extraction, and that the mercury levels are way below the tolerable limit values.

"There is no need to fix it (amalgam) if it is not broken," she added.
