Kari Rosakkan Warna Tampalan

ANTARA perkara lazim yang dilakukan oleh pakar gigi untuk mengelakkan gigi daripada terus diserang karies ialah membuat tampalan pada gigi tersebut.

Tampalan dapat melindungi bahkan menyelamatkan gigi daripada dibuang. Selalunya jangka hayat tampalan ditentukan oleh jenis tampalan dan bahan yang digunakan.

Menurut pensyarah Jabatan Periodontologi, Fakulti Pergigian, Universiti Kebangsaan Malaysia (UKM), Dr. Masfueh Razali, bahan tampalan ada yang sama warna dengan gigi dan sebaliknya.

Tampalan yang mempunyai warna seakan gigi adalah menggunakan komposit yang kandungan utamanya ialah methyl methacrylate dan silika, katanya.

Bagaimanapun, jelas Masfueh, komposit tersebut hanya sesuai digunakan bagi tampalan gigi hadapan.

Teen Lives 4 Months With No Heart, Leaves Hospital

This has nothing to do with teeth whitening, but the thing happen in Miami. Please read on.

– Teen Receives New Heart

MIAMI – D'Zhana Simmons says she felt like a "fake person" for 118 days when she had no heart beating in her chest. "But I know that I really was here," the 14-year-old said, "and I did live without a heart."

As she was being released Wednesday from a Miami hospital, the shy teen seemed in awe of what she's endured. Since July, she's had two heart transplants and survived with artificial heart pumps — but no heart — for four months between the transplants.

Last spring D'Zhana and her parents learned she had an enlarged heart that was too weak to sufficiently pump blood. They traveled from their home in Clinton, S.C. to Holtz Children's Hospital in Miami for a heart transplant.

But her new heart didn't work properly and could have ruptured so surgeons removed it two days later.

And they did something unusual, especially for a young patient: They replaced the heart with a pair of artificial pumping devices that kept blood flowing through her body until she could have a second transplant.

Dr. Peter Wearden, a cardiothoracic surgeon at Children's Hospital of Pittsburgh who works with the kind of pumps used in this case, said what the Miami medical team managed to do "is a big deal."

"For (more than) 100 days, there was no heart in this girl's body? That is pretty amazing," Wearden said. {Read From Original Source....}
