and when there are problems dentists often put the children asleep because they're scared. but we found that dentists can operate differently from many medical doctors and some say they are risking kids' lives. caleb's fears were normal for a 6-year-old boy, except for an extra tooth growing in his mouth. so he went to the dentist to have it pulled. to keep calm, the doctor gave him the medicine. >> he was scared. i was too, i told him to be brave and that it would be okay. >> i kissed him. and told him i'd see him soon. >> for caleb's procedure, the dentist, who is licensed as an oral surgeon was doing two jobs, pulling the tooth and administering anesthesia. four drugs, two narcotics were injected into his arm, but before the event, he stopped breathing, the dentist tried to open his air way but nothing work. his oxygen levels went down, he went into cardiac arrest. he was rushed to the hospital but had been without oxygen far too long in the dentist's chair, roughly seven minutes, his organs shut down, he lost all brain function. for the next two days, his parents agonized on whether or not they should keep him on life support. >> once we had information about his brain and consulted with a neurologist, we realized we had to let him go. i swore i would never leave the hospital without him, so to leave him there was the worst you could imagine. >> an autopsy report said he died in the hospital, but his parents believe he died in the dentist's chair, because the dentist was doing too much, acting as both the surgeon and the anesthesia administer. >> reporter: one surgeon said the practice of one person performing a procedure and giving anesthesia is never allowed at children's hospital and he believes it should never be allowed in dentist's offices. >> you have maybe a half a minute to make critical decisions on how to manage the child's air way. you can't do that if you don't have somebody economy there helping you. >> reporter: the california dental board regulates dentists and permits hundreds of specially trained dentists to do both jobs, but should it? consider propophol. >> and that would be somebody like myself doing this for their careers. >> and yet dentists who operate on their own regularly administer propofol on their own. so we wanted to know is caleb alone? is this practice safe? we asked the board how many people have died while having general anesthesia in a dentist's office. it could not tell us. instead it gave us three years of raw data, incidents reported by the medical community and their lawyers. the files are redacted and inconsistent. one person required a surgery and later died. one report ends quickly. in a two-sentence report a patient is taken to the hospital for cardiac evaluation but it doesn't tell us what happened next. we could not make sense of those reports so we asked the dental board for a review. we were told all 15 members were unavailable. a spokesperson took our questions on behalf of the board. >> is it safe? >> the board has not discussed that particular matter at this point. >> reporter: that answer is not good enough for caleb's parents. they have asked the legislature to change state law, to require a separate dentist to give anesthesia during pediatric procedures. but many groups support dividing the duties. one is not convinced. the california dental association. the association selected dr. paul reggirado to explain why. >> having a separate doctor in the room doesn't necessarily guarantee patient safety. >> it is upsetting. >> reporter: dr. patel disagrees. he is licensed to do both dental work and anesthesia at the same time. but he does not. for safety's sake, he brings in another dentist to give the anesthesia and has been doing it for 12 years. today he is operating with dr. christine yem, here is how they describe the death. >> completely preventible. >> so preventible. >> reporter: patel and yem are calling for change joining caleb's parents. >> i keep thinking i wish someone else had done this years ago and saved caleb. i really want to save caleb. >> reporter: caleb's dentist is still practicing. the dental board has accused him of gross negligence. right now his case is with the attorney general. right now there is a two-person committee to determine if two people should be present during general anesthesia. we still have many questions and will follow this story. in the meantime, if your child needs work in the dental office that requires general anesthesia, all the experts we talk to say you should talk to the dentist and ask whether or not another dentist will be present. you have the right to ask for one and also have the right to walk away. >> the pediatric doctor is so important. >> and if you have more information you can call or visit nbc bay area.com/response. all right, changing gears here, let's talk to meteorologist jeff ranieri, and another hot one tomorrow?
