      The objectives of this study were to evaluate the number and range of clinical procedures completed by undergraduate dental students in pediatric dentistry in Cork University Dental School and Hospital, Ireland, and to compare the number of procedures undertaken with the subsequent examination scores. The work comprised a retrospective audit of clinical logbooks for all of the undergraduate dental students in one cohort through their fourth and fifth clinical years between 2004 and 2006. Thirty-four quantitative logbooks were audited. Students had seen a total of 1,031 patients, and each student had completed a full course of dental treatment for an average of twenty-two children. Students completed means of 30.2 restorative procedures for children, fourteen in deciduous dentition (range six to twenty-eight), and seventeen in permanent dentition (range seven to twenty-eight). Continuity of education and care (measured through children having their treatment fully completed by the same student) was 72 percent. A moderate positive correlation between levels of clinical experience and exam score was identified. All students gained experience in management of child patients with students providing care for an average of thirty children and a minimum of nineteen.
    • Technical quality of root canal fillings performed in a dental school and the associated retention of root-filled teeth: a clinical follow-up study over a 5-year period.

      The aim of this study was to examine the technical quality of root canal fillings performed in a dental school and to investigate the associated effect on the survival/retention of root-filled teeth. A review of case notes of patients who had root canal treatment performed in the department of Restorative Dentistry, University Dental School and Hospital, Cork, Ireland was carried out. The technical quality of the root canal filling was described according to its relationship with the radiographic apex on a post-treatment radiograph. Tooth status at review was defined as 'tooth present' or 'tooth absent' based on the presence or absence of the root-filled tooth recorded in the treatment records at a review appointment following placement of the root canal filling. One hundred and forty-eight teeth (129 patients) were considered. Of these, 69.6% (n = 103) were of acceptable technical quality, 23.6% (n = 35) were under-extended, and 6.8% (n = 10) were overextended. An increased number of intra-treatment radiographs to confirm the relationship of the canal preparation to the radiographic apex and operator experience were significant predictors of adequate root canal fillings (P < 0.05). Eighty-three per cent (n = 123) of teeth were present at a review appointment held an average of 40 months following completion of treatment (12-60 months). The technical quality of the root canal filling was the only significant factor in predicting tooth survival (P < 0.05), while the presence of pre-treatment periapical pathology had no significant effect on survival of the root-filled tooth. Determination and maintenance of the working length of the canal system is an important feature in producing good quality root canal fillings, which in turn, is associated with increased likelihood of survival/retention of root-filled teeth.
