The Relationship of Caries Risk and Oral Hygiene Level with Placement and Replacement of Dental Restorations
Objectives. To assess the caries risk and oral hygiene level that affect the placement and replacement of restorations.
Materials and Methods. A practice-based study performed in private clinics. A total of 76 dentists participated. The sample consisted of 10,076 restorations of >14-year old patients collected by volunteer dentists over a period of two months. Clinicians were asked to record the details of their patients and also the state of oral hygiene and caries risk of each patient. The data were analysed using Microsoft Excel and SPSS 20.00 software. It was considered that a P value less than 0.05 was significant.
Results. 50.9% restorations replaced were due to secondary caries with moderate oral hygiene, with no significant differences. Of Class II type, 75% were replaced in moderate oral hygiene with a significant difference. There was a significant difference between the use of amalgam and composite according to the state of oral hygiene. 47.7% of the individuals who had their restorations replaced due to secondary caries had high caries risk. According to CI II cavity type, it was shown that 70.5% of the patients had moderate and 23% of the patients had high caries risk.
Conclusion. Most restorations were replaced due to secondary caries. There is a synergetic relationship between oral hygiene level and caries risk in patients and the possibility of secondary caries development and restoration replacement.
