Children with a decayed baby tooth usually meet a drill, and often a needle before it. Hand excavation is the alternative: the decay is scraped out with a spoon excavator or the atraumatic restorative treatment set, more slowly, but sometimes without an injection and without the noise and the vibration children mind most. Whether that is genuinely less painful or only slower is not settled, and it matters well past the appointment, because a frightening first filling is one of the things that produces an adult who avoids dentists. The trials that compared the two are small, and they measure pain on several different scales, some of which ask the child and some of which ask the person watching, so they disagree partly because they are not measuring the same thing. This project reads them together and sets out what can be said about the pain, about the injection, about how long each method takes and about whether the filling lasts. It is written for a dentist who has to choose one of the two on a Monday morning, and it is a semester of reading and tabulating to get there.
Read up on how caries is taken out of a baby tooth, by drill and by hand. Take one outcome, read the papers already gathered for it, tabulate what each trial found, and write that section of the review.
