The field of dentistry is currently undergoing a remarkable paradigm shift. From conventional methods characterized by lengthy chemical processes and large amounts of medical waste, dental healthcare is now moving toward comprehensive digitalization that not only ensures diagnostic accuracy but also embraces environmental sustainability, a concept known as Green Dentistry. This transformative movement was prominently featured in a series of international scientific forums at the International Kintar Summer Parcs 2026, which brought together experts from various disciplines to redesign the future of global dental practice.
Eliminating Chemical Waste Through Digital Radiology
One of the key pillars driving this transformation is the revolution in dental imaging. Dr. drg. Rurie Ratna S, MDSc, Sp.R.Rad.G., a dental radiology specialist also known as Dr. Ruri, provided a comprehensive overview of how digital radiology technology has transformed clinical care. First-generation radiography, which relied on conventional film, is now increasingly being phased out. The old method was not only time-consuming because it required processing in a darkroom, but also generated hazardous waste such as lead and chemical developer solutions that could potentially contaminate the environment.
“Digital radiology makes a major contribution to sustainability by improving efficiency, reducing environmental impact, and optimizing radiation protection,” explained Dr. drg. Rurie Ratna S, MDSc, Sp.R.Rad.G. The introduction of Photostimulable Phosphor (PSP) technology and modern intraoral sensors (CCD/CMOS) allows clinical images to appear instantly on monitors without generating toxic chemical waste.
More advanced still, Cone Beam Computed Tomography (CBCT) provides three-dimensional (3D) visualization with remarkable anatomical detail using the smallest unit of measurement, the voxel. The use of CBCT together with artificial intelligence (AI) has now become a gold standard for implant planning and complex surgery because it provides high geometric accuracy with a much lower radiation dose than conventional CT scans.
A Global Commitment to Protecting an Ailing Planet
The digitalization of radiology directly intersects with the concept of Green Dentistry, which was clearly presented by Prof. Michelle Sunico-Segara, BDM, MOH, PhD. The Dean of the University of the Philippines College of Dentistry and Vice President of Healthcare Without Harm East Asia emphasized a profound message: “There are no healthy people on a sick planet.”
As part of the Global Green and Healthy Hospitals movement, dental education institutions worldwide are now encouraged to adopt environmentally friendly agendas. One major achievement highlighted was the complete elimination of dental amalgam—a conventional silver-colored filling material containing toxic mercury—and its replacement with alternatives such as composite resin. However, this transition presents a new challenge because residual composite resin is classified as plastic waste, requiring dental practitioners to prioritize preventive measures to prevent dental caries from developing in the first place.
Through the 4R principles—Reduce, Reuse, Recycle, Rethink—modern dental services are encouraged to reduce single-use plastic personal protective equipment (PPE) waste and optimize integrated digital medical record systems. The cutting-edge collaboration between the diagnostic precision of digital radiology and environmental advocacy demonstrates that the future of dentistry is not solely focused on treating patients, but also on protecting the planet we call home.
