LEARNING that you have tooth decay can be upsetting, but you’re not the only one getting this news at the dentist’s office.

There are many types of dental fillings, and both metal and metal-free fillings are available. The best type of filling for a cavity will depend on many factors, including the cavity’s size and location, and your dentist can recommend the best type for your situation.

 

Metal fillings

Dental amalgam fillings, also known as silver-coloured fillings, are made of a mixture of metals. These are comprised of liquid mercury and powdered copper, silver and tin. The mercury reacts with the other components, binding them together into a durable material. Dental amalgam’s durability makes it a good option for large cavities in the back teeth. Amalgam fillings have been used in dentistry for more than 100 years.

Gold fillings are also made of a mixture of metals, including gold and copper. They are also known as inlays or onlays. These are the most durable type of filling and can last for more than 20 years.

 

Metal-free fillings

Composite fillings, also known as tooth-coloured fillings, are made of a mixture of resin and glass. These fillings look more natural than metal fillings, but they may need to be replaced more often.

Glass ionomer fillings are also tooth-coloured, and they’re made of powdered glass. These fillings form a chemical bond with the teeth after application.

 

Potential advantages of metal-free fillings

While both metal and metal-free fillings can be used to repair cavities, there are a few situations in which dentists may recommend the latter type. Since metal-free fillings are the same colour as your teeth, they look more natural than their metal counterparts. This may be an important consideration if you have a cavity in one of your front teeth or if you’re concerned with the appearance of your filling.

Glass ionomer fillings have another potential advantage. These fillings may release fluoride, which is a naturally occurring mineral that helps strengthen tooth enamel and prevent future decay.

 

Safety of metal fillings

For those who may have concerns about the mercury content in dental amalgam fillings, scientific studies have consistently found dental amalgam to be safe. The type of mercury found in dental fillings isn’t the same kind that can build up in fish and cause health problems.

Further, studies haven’t found any links between dental amalgam fillings and health problems in the general population.

Some people may have allergies or sensitivities to the materials used in metal fillings. For these people, metal fillings can cause contact reactions, such as sores inside the mouth. If you have any allergies or sensitivities to metals, like copper or tin, let your dentist know.

If left untreated, cavities will only get worse. So, if your dentist says you need a filling, don’t delay. Many types of metal and metal-free fillings can be used to repair tooth decay. If you have questions or concerns about dental filling materials, talk to your dentist.

Gov’t gets support from Church to fight challenge to buggery laws

KINGSTOWN, St Vincent (CMC) — High Court Judge Justice Esco Henry yesterday ruled to allow 10 churches, calling themselves the Christian Coalition, to join the Ralph Gonsalves Government in responding to the constitutional challenge to the buggery and gross indecency laws in St Vincent and the Grenadines.

Justice Henry handed down the ruling one week after hearing arguments from the Christian Coalition and lawyers for the claimants, gay Vincentians Sean MacLeish and Javin Johnson.

Shirlan “Zita” Barnwell, one of the two lawyers representing the claimants, told the Caribbean Media Corporation (CMC) that the judge agreed to allow the churches to join the lawsuit as an interested party.

He said they will be allowed to file written submissions and make oral arguments to the court.

However, in terms of evidence, the churches are restricted to filing two affidavits, Barnwell said.

Justice Henry is expected to issue her written ruling today.

Barnwell and Jomo Thomas are representing the claimants, who say the country’s anti-buggery and gross indecency laws contravene their constitutional rights.

Under the Criminal Code, any person who commits buggery with any other person, commits buggery with an animal, or permits any person to commit buggery with him or her is guilty of an offence and liable to imprisonment for 10 years.

The Criminal Code also says that any person who, whether in public or private, commits any act of gross indecency with another person of the same sex, or procures or attempts to procure another person of the same sex to commit an act of gross indecency with him or her, is guilty of an offence and liable to imprisonment for five years.

The men are asking the court to declare the laws unconstitutional, void and of no effect.

Ten churches had asked to join the attorney general in responding to the challenge to these laws. They include the Seventh-day Adventist Church; Evangelical Church of the West Indies; New Testament Church of God; Spiritual Baptist Church; Church of God St  Vincent; New Life Ministries; Light of Truth Church of God; Kingstown Baptist Church; Living Water Ministries International; and Hope Evangelism Outreach Ministries.

Last week Wednesday, hundreds of Vincentians took to the streets in support of the present legislation and urged the authorities not to amend the legislation to suit the claimants.

BRIDGETOWN, Barbados (CMC) — The United Nations Development Programme (UNDP) is launching a multi million-dollar project in nine Caribbean countries that will enable gender responsive disaster recovery, climate and environmental resilience (EnGenDER) in the Caribbean.

The US$15 million project will ensure equal access to sustainable solutions for the improved resilience of women and men in Antigua and Barbuda, Belize, Dominica, Grenada, Guyana, Jamaica, St Lucia, St Vincent and the Grenadines and Suriname.

It is being funded by Canada and the United Kingdom Department for International Development.

UNDP said that its prior support to the development of National Adaptation Plans (NAPs) and Nationally Appropriate Mitigation Actions (NAMAs) will now be scaled up as a result of the new project.

The NAP process was created by the United Nations as an opportunity for countries to plan for sustainable development in the face of climate stress while NAMAs, on the other hand, focus on mitigation – reducing greenhouse gas (GHG) emissions.

EnGenDER will support the implementation of priority areas, as identified by partner governments, within these policy documents, ensuring that plans are gender-responsive – considering the vulnerabilities, strengths and needs of different groups of women and men. This work will be undertaken through consultative and participatory approaches, with key stakeholders identifying and leading priority actions.

UNDP resident representative for Barbados and the Organisation of Eastern Caribbean States (OECS) Magdy Martinez Soliman, said “Canada and the United Kingdom have been working collaboratively in the region for many years and this project provides a new opportunity to demonstrate our commitment to increasing resilience in the Caribbean.

“It is anticipated that the partnerships built at the regional and national levels will produce important results as the region faces the increasing impacts of climate change.”

The UNDP said that it is coordinating the collaborative project that includes UN Women, partnering to build capacity in developing gender-responsive plans, and conducting behavioural analysis of gender-responsiveness in risk governance among decision makers as well as the World Food Programme (WFP), which is working to enhance social protection systems to make them more shock-responsive.

EnGenDER will integrate a gender equality and human rights-based approach into disaster risk reduction, climate change adaptation and environmental actions.
