The autopsy report on Juthamas Chaiyason cited "thyroid poisoning" and "cardiac arrest" as the causes of death.
She died on Sunday in the emergency unit of a local hospital, after complaining of severe tooth-ache for several days following her trip to have coloured braces fitted. The braces are fitted by dentists as a purely cosmetic procedure with no physically beneficial effects, but unqualified practitioners also offer the service.
Poisoning and infection
Juthamas's parents took her to hospital on August 20, 10 days after the braces were fitted, where the girl was diagnosed with thyroid poisoning and cardiovascular infection and sent home with medication.
Her mother, Niannapha, reports that Juthamas passed out the next day after having trouble breathing. She was taken to hospital, where she was pronounced dead on Sunday night.
Dentist Rattana Thong-kham expressed concern about the trend for coloured braces, which are becoming popular among teenagers.
