Research summary
This research will undertake two cross sectional studies at School of Dentistry, University of Leeds. Both studies involve carious baby molar teeth. These teeth will be extracted under general anaesthesia as part of the patients normal routine treatment.
First study (STUDY A): This study will investigate the extent of dental decay, as it appears on dental radiographs, at which cavitation may occur.
Dental caries initially is reversible. Once the enamel cavitates restorative treatment is required. This study will investigate at what radiographic extent of decay in primary molar teeth does cavitation occur.
For this study, teeth will be examined visually, radiographically and histologically. Teeth will be examined radiographically before extraction to measure the extent of decay, as appear on radiographs. Teeth will be examined visually before and after extraction and will be scored as cavitated or not cavitated. Before extraction, teeth will be cleaned and dried for visual examination under general anaesthesia. Then teeth will be scored using ICDAS (1). After extraction, teeth will be cleaned and dried and will be examined and scored using ICDAS.
Then teeth will be sectioned to measure the extension of carious histologically.
Visual, radiographic and histological findings will be compared to each other.Second study (STUDY B): This study will describe the relationship between the real thickness of remaining dental tissue below deep decay and its appearance on dental radiographs in baby molar teeth.
Pre extraction radiographs will be used to measure the remaining dentine thickness below deep carious lesions. After extraction, teeth will be sectioned and examined clinically to measure the real remaining dentine thickness. The clinical remaining dentine thickness will be compared to the radiographic remaining dentine thickness to assess the reliability of dental radiograph in measuring the remaining dentine thickness.(1) ICDAS: International Caries Detection and Assessment system used to detect the presence and extension of decay
