Fungal pneumonia is caused by overgrowth of the fungi in the lungs. Fungal lung infections are usually only seen in those with a poorly functioning immune system, such as those with AIDS.

Step 2: Complete a Dental Hygienist Program. Once you have decided which focus you prefer, you may enroll in the appropriate type of dental hygiene program. Certificate and associate's degree programs typically take two years to complete, while bachelor's degree programs typically take four.
Dental hygienist certificate programs are often available at community colleges or university schools of dentistry. Most prepare you to pass national and state dental hygiene licensing exams upon graduation. Some may even allow you to transfer your credits to a dental hygiene associate's or bachelor's degree program.ental hygienist certificate programs are often available at community colleges or university schools of dentistry.
