Referencing Styles : Not Selected Unit 302 – Using research skills to solve problems. What is required to do is to complete the assessment criteria 1.1 to 1.4 and 2.1 to 2.5. I have attached an image of the assessment pages 1 & 2. 1.1 – It has to be a problem that occurs often at a dental practice e.g waiting time – patients are waiting longer than suppose to or dentists are spending too much time on patients. Or poor dental care, gum disease, missing teeth, sensitivity.. Or something even better..Something that has to do with dentistry – a problem that you think occurs most. Thank You. .
