      Al-Khaldi, Nasser; Sleeman, Duncan; Allen, Finbarr; Private Dental Practice, Muscat, Oman. (2010-06-06)
      We aimed to assess the stability over time of dental implants placed in grafted bone in the maxilla using resonance frequency analysis, and to compare the stability of implants placed in grafted and non-grafted bone. Data were collected from 23 patients (15 test and 8 controls) in whom 64 implants (Brånemark system, Nobel Biocare, Göteborg, Sweden) were placed in accordance with the two-stage surgical protocol. In the test group 36 fixtures were placed in grafted bone, and in the control group 28 fixtures were placed in non-grafted bone. Resonance frequency analysis was used to assess the test sites at implant placement and abutment connection. The mean (SD) implant stability quotient (ISQ) for test sites at the time of implant placement was 61.91 (6.68), indicating excellent primary stability, and was 63.53 (5.76) at abutment connection. ISQ values at abutment connection were similar for test and control sites. Implants placed in grafted bone compared favourably with those in non-grafted bone, and showed excellent stability.
    • State-of-the-art techniques in operative dentistry: contemporary teaching of posterior composites in UK and Irish dental schools.

      Lynch, C D; Frazier, K B; McConnell, R J; Blum, I R; Wilson, N H F; Restorative Dentistry, Tissue Engineering & Reparative Dentistry, School of Dentistry, Cardiff University, Heath Park, Cardiff, CF14 4XY. lynchcd@cardiff.ac.uk (2010-08-14)
      Advances of composite systems and their application have revolutionised the management of posterior teeth affected by caries, facilitating a minimally invasive approach. Previous surveys have indicated that the teaching of posterior composites within dental schools was developing, albeit not keeping pace with clinical evidence and the development of increasingly predictable techniques and materials. Concurrently, surveys of dental practice indicate that dental amalgam still predominates as the 'material of choice' for the restoration of posterior teeth within UK general dental practice. In light of such considerations, the aim of this study was to investigate current teaching of posterior composites in Irish and UK dental schools.

    • Systemic diseases and the elderly.

      McCreary, Christine; Ni Riordáin, Richeal; Oral Medicine Unit, Cork University Dental School and Hospital, Wilton, Cork, Ireland. (2010-11)
      Although systemic diseases can occur at any age, they are more common in older patients. Accurate and detailed medical and drug histories are important in dental practice as many conditions and medications can influence oral health and dental care in patients. Not only can these conditions influence patient care in the surgery and oral hygiene at home, but access to dental services may also be adversely affected. Clinical Relevance: The systemic diseases can impact upon oral care or can have oral manifestations. Many of the pharmacological interventions prescribed for chronic conditions can have multiple and diverse adverse effects on the oral environment.
    • 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.

      Burke, F M; Lynch, C D; Ní Ríordáin, R; Hannigan, A; University Dental School & Hospital, University College, Cork, Ireland. (2009-07)
      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.
