After a successful dental procedure, giant panda Xiaopingping
can get on with eating, free of pain.
The relieved 17-year-old, a grandpa by his age, became the first
panda in China to receive such treatment.
Doctors from the Huaxi (west China) Institute of Stomatology,
part of Sichuan
University in Chengdu in southwestern Sichuan
Province, put fillings in the root canals of three of the
panda's teeth.
Thursday's operation took about two hours.
Meanwhile, 18-year-old Bobo had two of his teeth disinfected,
the first step in root canal therapy, according Li Jiyao, one of
the doctors.
Both male pandas live at the Chengdu Panda Base, home to more
than 40 giant pandas.
Doctors will undertake the second step of the operation to clean
up the root canals of Bobo's two teeth in two weeks time.
As they get older, pandas' teeth rub and become damaged while
they eat, Li said.
She said they firstly disinfected Xiaopingping's troublesome
teeth last September, after they heard the panda had difficulty
eating.
In February they thoroughly cleared out his root canals.
Wang Chengdong, head of the animal hospital at the base, said
the process was prolonged because the panda was mating with females
during that period.
Wang said a third panda living at the base was found to have a
similar problem, and will soon be treated.
"We are carrying out a thorough check to see if any other pandas
have got the affliction," he said.
According to Wang, eight of the 12 female pandas at the base
have mated this year. The rest will complete mating by early
June.
But whether or not they can get pregnant and finally give birth
is unknown, he added.
The extremely low birth rate among pandas threatens to push the
animals to the brink of extinction.
Pandas, usually living to 20-26 years, are among the world's
most endangered wildlife species.
Statistics from the State Forestry Administration show the
number of pandas in the wild in China has risen from about 1,100 in
the late 1980s to 1,590 currently.
At the same time, about 160 live in captivity.
