Tooth is missing
Charting a treatment that marks a tooth as missing will graphically remove the icon for the tooth from both the dental chart and the perio chart. This means that you will not be able to chart any further treatment on that tooth. This typically happens following an extraction or another treatment that marks the tooth as missing.
If the tooth has been removed, but you will need to chart treatment in the future, such as replacing it with an implant, you need the tooth to be shown as present, even if it isn't physically there. Therefore, you do not want that tooth to be marked as missing.
Reset the Tooth
Charting a reset on a tooth will graphically remove any charted icons on it. You do not remove any treatment but retain all the treatment history in the treatment plans, which you can access through the History tab, from the Chart screen.
Examples of when you might use a reset include:
You might use this when a tooth has been marked as unerupted in the past and now it needs to show as fully present. The tooth may now have erupted.
If you have charted an extraction, not only does the extraction remove the tooth graphically, it removes all the previously charted icons on the tooth. The treatment remains visible in the history. An extraction or any treatment that marks the tooth as missing means that there is no tooth to chart dental or perio treatment against. You may now need to chart an implant and need the tooth to be marked as present in order to facilitate this.
