[{'content': 'A 13 year old male patient presents to the clinic for routine dental examination and has a history of frequent snacking and brushes twice a day.

Cariogram', 'role': 'user'}, {'content': 'Answer: D \nExplanation: When\xa0 discussing\xa0 caries\xa0 risk\xa0 and\xa0 introducing the “Cariogram,” Petersson repeated the complex nature of dental caries and the difficulties in predicting the development of the disease in any one patient. Over the years\xa0 these\xa0 difficulties\xa0 have\xa0 not\xa0 decreased.\xa0 There\xa0 are\xa0 several tools for predicting dental caries development. In 2012 Tellez conducted a systematic review of caries-risk assessment tools and concluded, “There is an urgent need to\xa0 develop\xa0 valid\xa0 and\xa0 reliable\xa0 methods\xa0 for\xa0 caries\xa0 risk\xa0 assessment\xa0 that\xa0 are\xa0 based\xa0 on\xa0 best\xa0 evidence\xa0 for\xa0 prediction and\xa0 disease\xa0 epidemiology\xa0 management\xa0 rather\xa0 than\xa0 opinions of experts.” In this review the four most commonly used caries-risk assessment tools were reviewed (Cariogram,\xa0 Caries\xa0 Management\xa0 by\xa0 Risk\xa0 Assessment\xa0 , American Dental Association, and the American Academy of Pediatric Dentistry) and were found to be of equal value.\xa0\nThe Cariogram has been evaluated and found to be more predictive in\xa0 permanent\xa0 teeth than\xa0 with\xa0 preschool children.\xa0\nThe “Cariogram” is a computer caries-risk program that records several data points including past caries experience, diet, oral hygiene habits, fluoride exposures, and analysis of saliva. The program then produces the results as a coloured graph. This was well described by Gonzalez and Okunseri in 2010. Cariogram was given by Brathall et al in 1999. It is a method of illustrating the interaction of factor contributing to the development of caries. The different colors are as follows: red for bacteria, dark blue for diet, light blue for susceptibility-related factors, and yellow for circumstances.
