Hi, im not aware of this particular case study but in terms of writing a script and giving an oral health session in a first person narrative setting I would start by using "I advise to my patients..."or "we advise to our patients".
A session on oral health would be specific to the patient, consider their age, and medical history. Then you would set two aims for the patient. Ie: a child age 6 with poor manual dexterity. My advise would be to brush effectively for two minutes twice a day (once before bed and one other time) using a small medium textured toothbrush with a 1000ppm fluoride toothpaste and use disclosing tablets once a week. Also mention diet at this is included in oral health is: reduce and restrict sugar intake and acidic fruit juices to meal times only..hope this helps
