The importance of primary caries
prevention is acknowledged by the coordinators and clinical instructors of the UBC CDP.
According to this survey in Saudi population, the primary caries
were present in 80% of the children with mean DMFT value of 5.11 The mean DMFT that has been calculated in the present study is 2.24, which is lower as compared to the above mentioned study.
(1) The development of secondary caries is similar to that of primary caries
but differs according to the location and characteristics of the surface, such as roughness and marginal defects.
Regarding the scope of practice, although there are many states with dental practice acts that limit what non-dental oral health care providers can do, no medical practice act precludes a physician from doing primary caries prevention (gross oral examination, paper-and-pencil caries risk assessment, application of fluoride varnish, educating the caregiver about caries etiology and the caregiver's role in prevention, referring those who need care to a dentist and informing the caregiver about the importance of the child's having a dental home by age 1).
He has developed training materials for primary care medical providers to include primary caries prevention during well-child care and is instrumental in ongoing efforts to achieve Medicaid reimbursement nationwide for these providers to apply fluoride varnish.
Yeast cells are certainly acidogenic microorganisms, but the primary caries
process has not yet been linked to the presence of yeast cells.
The information obtained in the study is necessary in order to evaluate and plan primary caries
prevention programs at the community level in Puerto Rico.
Other changes in the epidemiology, such as the delay in the rate of disease progression, mean that older teens and young adults are experiencing primary caries
. By age 18, more than 81% have experienced dental decay, and by 34-44 years of age, close to 100% are affected. These data create quite a different picture from the one the public and dental profession may have when reading that over half the U.S.
2094 amalgam restorations met the criteria for the study with primary caries accounting for 74.2 Percent (1553 restorations), primary placements accounted for 75.7 Percent , replacements were 24.3 Percent of the replaced amalgam, fractured amalgam constituted 66.00, Secondary caries 11.6 Percent Secondary caries was not the major reason in this study for replacement of amalgam restorations.
Primary caries Secondary caries Bulk fracture Marginal failure/ditching Dislodged restoration Cervical abrasion Others - attrition, overhanging restoration, frac- tured cusp/s etc.
Mehmood S et al3 have reported the primary caries as a major reason for the initial resto-
The major reason for placement of new restoration was primary caries (84.3%) followed by tooth fracture (2.3%) and non-carious defect (1.1%) respectively.
