Centrum - yes, this is a specialty you would match into. The ASDA book of specialties lists 13 programs around the country. It isn't too competitive, with acceptance:applicant ratios given between 1:3 to 1:8 for each program. This specialty is kinda an academic one, in that you wouldn't exactly set up a private office next to the periodontist and orthodontist. Since you don't have a private office, it's not an instant money maker like the other specialties so it's not as popular (at least this is what an oral pathologist at school told me). Many times the oral pathologists work at and are affiliated with a dental school or maybe a hospital. However, they are a key part of denitstry. They diagnose some pretty cool stuff and oral path is probably one of the most important classes you will take in dental school that you use on a daily basis with all your patients, regardless of whether you are a general dentist or an endodontist.
