Ultrasonic teeth cleaning procedures might not be suitable for everyone, the Food and Drug Administration (FDA) said on Tuesday, advising people with hemophilia or similar conditions, pacemakers, congenital heart problems, acute bacterial endocarditis, chronic lung disease or those who have had heart valve replacement surgery not to undergo the treatment.
Ultrasonic cleaners operate using an electromagnetic field, which, with its high vibration rate, can swiftly and efficiently remove dental calculus, but could be fatal for people with pacemakers, as the electromagnetic field could interfere with its discharge rate, the FDA said.
The operator is responsible for adjusting the strength of the electromagnetic field, it said.
Ultrasonic cleaning can cause minor injuries to the gums, so people with hemophilia face infection risks, it said.
Bacterial infection of the gums could enter the bloodstream and reach the heart, causing endocarditis, it said.
RESPIRATORY RISK
Residual tartar removed during the debridement process could block the respiratory tract and could prove fatal for those with chronic lung disease, the FDA said.
The agency called on people to inform their dentist if they have any of the conditions so the best teeth-cleaning method would be used.
The military has spotted two Chinese warships operating in waters near Penghu County in the Taiwan Strait and sent its own naval and air forces to monitor the vessels, the Ministry of National Defense (MND) said. Beijing sends warships and warplanes into the waters and skies around Taiwan on an almost daily basis, drawing condemnation from Taipei. While the ministry offers daily updates on the locations of Chinese military aircraft, it only rarely gives details of where Chinese warships are operating, generally only when it detects aircraft carriers, as happened last week. A Chinese destroyer and a frigate entered waters to the southwest
A magnitude 6.1 earthquake struck off the coast of Yilan County at 8:39pm tonight, the Central Weather Administration (CWA) said, with no immediate reports of damage or injuries. The epicenter was 38.7km east-northeast of Yilan County Hall at a focal depth of 98.3km, the CWA’s Seismological Center said. The quake’s maximum intensity, which gauges the actual physical effect of a seismic event, was a level 4 on Taiwan’s 7-tier intensity scale, the center said. That intensity level was recorded in Yilan County’s Nanao Township (南澳), Hsinchu County’s Guansi Township (關西), Nantou County’s Hehuanshan (合歡山) and Hualien County’s Yanliao (鹽寮). An intensity of 3 was
Instead of focusing solely on the threat of a full-scale military invasion, the US and its allies must prepare for a potential Chinese “quarantine” of Taiwan enforced through customs inspections, Stanford University Hoover fellow Eyck Freymann said in a Foreign Affairs article published on Wednesday. China could use various “gray zone” tactics in “reconfiguring the regional and ultimately the global economic order without a war,” said Freymann, who is also a nonresident research fellow at the US Naval War College. China might seize control of Taiwan’s links to the outside world by requiring all flights and ships entering or leaving Taiwan
The next minimum wage hike is expected to exceed NT$30,000, President William Lai (賴清德) said yesterday during an award ceremony honoring “model workers,” including migrant workers, at the Presidential Office ahead of Workers’ Day today. Lai said he wished to thank the awardees on behalf of the nation and extend his most sincere respect for their hard work, on which Taiwan’s prosperity has been built. Lai specifically thanked 10 migrant workers selected for the award, saying that although they left their home countries to further their own goals, their efforts have benefited Taiwan as well. The nation’s industrial sector and small businesses lay
