When you help out a colleague

I've been helping out my junior colleagues lately mainly in extraction clinic. Some tips for myself in the future when I do this are:

-Don't rush into the procedure, they are struggling in the middle of a procedure but it doesn't mean you have to rush in and struggle. Introduce yourself to the patient, ask what the situation is and the problem they are encountering. If yo don't do this then you may run into the same problem. Look at the xrays and check the notes if you need to before tackling the problem. Don't pick up an instrument straight away. Survey the area and plan out what you are going to do.
-Often times the benefit you will provide is a fresh perspective on things. They have been looking at this particular tooth for a long while and the detail tends to be blurred especially if they are panicking. Your fresh set of eyes may find something they have missed or been too distracted to notice.
-Don't be mean, be firm but know that you are acting in the best interest of the patient and your colleague.
-Ask if they want you to take over the procedure or just provide advice. To an extent you want to demonstrate what you are talking about but you want them to have a feel of the mechanics behind the procedure.
- If they are panicking, the first priority is to calm them down. They will be assisting you for the next bit of the procedure so everyone involved needs a level head before you proceed. If they cannot concentrate then they won't be able to learn. If all they want you to do is fix their mistake then they will keep making the same mistakes over and over.
