      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.

      Abstract Objective: To evaluate 3D nasal morphology following primary reconstruction in children with unilateral cleft lip and palate relative to contemporaneous non-cleft data Design: Prospective, cross-sectional, controlled study. Setting: Glasgow Dental Hospital & School, Faculty of Medicine, Glasgow University Patients and Participants: Two groups of 3-year old children (21 with unilateral cleft lip and palate and 96 controls) with facial images taken using a 3D vision based capture technique. Methods: 3D images of the face were reflected so the cleft was on the left side to create a homogenous group for statistical analysis. Three-dimensional co-ordinates of anthropometric landmarks were extracted from facial images by a single operator. A set of linear measurements was utilised to compare cleft and control subjects on right and left sides, adjusting for sex differences Results: the mean nasal base width and the width of the nostril floor on right and left sides differed significantly between control and Unilateral Cleft Lip and Palate (UCLP) groups. The measurements were greater in UCLP children. The difference in the mean nasal height and mean nasal projection between the groups were not statistically significant. Mean columellar lengths were different between the left and right sides in UCLP cases. Conclusions: There were significant nasal deformities following the surgical repair of UCLP. Keywords: child, cleft lip and palate, three-dimensional imaging.

      Abstract Objective: To evaluate 3D lip morphology, following primary reconstruction in children with unilateral cleft lip and palate (UCLP) relative to contemporaneous non-cleft data Design: Prospective, cross-sectional, controlled study Setting: Glasgow Dental Hospital & School, University of Glasgow, The UK. Patients and Participants: Two groups of 3-year old children (21 with unilateral cleft lip and palate and 96 controls) with facial images taken using a 3D vision based capture technique. Methods: 3D images of the face were reflected so the cleft was on the left side to create a homogenous group for statistical analysis. Three-dimensional co-ordinates of anthropometric landmarks were extracted from facial images. 3D generalised Procustes superimposition was employed and a set of linear measurements were utilised to compare between cleft and control subjects for right and left sides, adjusting for sex differences. Results: Christa philteri on both the cleft and non-cleft sides were displaced laterally and posteriorly; there was also a statistically significant increase in philtrum width. No significant differences between cleft and control regarding the cutaneous height of the upper lip. The lip in the cleft cases was flatter than in the non-cleft cases with less prominence of labialis superioris. Conclusions: Stereophotogrammetry allows detection of residual dysmorphology following cleft repair. There was significant increase of the philtrum width. The lip appeared flatter and more posterior displaced in Unilateral Cleft Lip and Palate (UCLP) cases compared with control. Keywords: child, cleft lip and palate, lip repair, three-dimensional imaging.
    • Timing of pulp extirpation for replanted avulsed teeth.

      Stewart, Chris; Dept Paediatric Dentistry, Cork University Dental School and Hospital, Cork, Ireland. (2009)
      There is clinical evidence for an association between pulp extirpation performed after 14 days following replantation and the development of inflammatory resorption. This investigation supports the current clinical guidelines for pulp extirpation within 10-14 days of replantation.
    • Tooth size discrepancies in Irish orthodontic patients among different malocclusion groups.

      O'Mahony, Gerard; Millett, Declan T; Barry, Mark K; McIntyre, Grant T; Cronin, Michael S; Cork University Dental School and Hospital, Wilton, Ireland. (2011-01)
      The prevalence of anterior tooth size discrepancies in this sample of Irish orthodontic patients was 37.9%. There were no statistically significant differences in the prevalence of mean overall TSDs with regard to malocclusion or gender. In the male group, the mean anterior tooth size ratio was higher in Class III and in Class II division 2 malocclusion than in Class II division 1 and higher in Class II division 2 malocclusion than in Class I malocclusion.

    • The use of quality of life measures in oral medicine: a review of the literature.

      Riordain, R Ni; McCreary, C; Oral Medicine Unit, Cork University Dental School and Hospital, Wilton, Cork, Ireland. richeal.niriordain@ucc.ie (2010-07)
      The evaluation of quality of life in oral medicine has a broad applicability, providing information in treatment-based studies and population-based studies. A predominance of generic and oral health specific quality of life measures are being used to a limited extent in oral medicine practice. A scarcity of reports of the development, validation or use of disease specific measures is evident.
    • Water fluoridation.

      Water fluoridation, where technically feasible and culturally acceptable, remains a relevant and valid choice as a population measure for the prevention of dental caries.
