Five-year-old Daniel appears to be shy. He always looks at the floor, has no friends, never plays with the other children, and will rarely speak to adults, and when he does speak, it is difficult to understand his broken enunciation. His skinny frame and the dark circles under his eyes make him appear malnourished. Daniel cries frequently and misses many days of school. A speech specialist at school finds that only two of Daniel’s teeth are healthy; all the others have rotted away to the gum line. The little guy is in constant pain and it hurts to chew. A doctor later determines that bacteria from the cavities in his mouth have entered his bloodstream and infected his heart, causing an irregular heartbeat and poor blood circulation. 1. How are biofilms to blain for the bulk of Daniel’s problems? 2. A recent study has shown that brushing does more than clean plaque from the teeth; it also disrupts associations between oral bacteria. How does this simple act help prevent the formation of biofilms? 3. What is the scientific nutrient should Daniel’s parents eliminate from his diet to help prevent a repeat of this condition? 4. What can Daniel, his parents, and health care professionals do to cure his diseases?

1. brushing the teeth removes the dental plaque causing a reduction of bacterial flora in the mouth

2. brushing with dentifrice it is a mechanical denture hygiene method to eliminate biofilm, bacterias as S. aureus, S. mutans, and P. aeruginosa; E. faecalis, C. albicans, and C. glabrata displayed a greater reduction in cell numbers when a mechanical method was used.

3. S. mutans is most often associated with cavity formation and this bacteria is glucose fed, so high sugar foods help their proliferation causing a higher risk factor

4. As the causes are multifactorial, you should start with good nutrition, follow strict dental hygiene that includes brushing, flossing, and mouthwash, periodic visits to the dentist, this will eliminate the source.

Explanation:

The mouth is a source of bacteria associated with systemic diseases, for this reason, the biofilm forms an important relationship in health, when we do not have good dental hygiene, small portions of food accumulate in the spaces between the teeth causing a source of bacterial proliferation,

and the biofilm begins to form whit the adherence of bacteria to a tooth surface, then a rapid growth occurs, forming colonial bacteria that can enter the bloodstream from a small wound

d. the weight of the book

c is the correct answer hope this !
