Craniofacial morphology and soft tissue profile outcomes for complete unilateral and complete bilateral cleft lip and palate in New Zealand.

OBJECTIVE: (a) To establish baseline lateral craniofacial morphology and soft tissue profile outcomes for New Zealand children with complete unilateral and complete bilateral cleft lip and palate (CUCLP/CBCLP) and determine differences in relation to demographic characteristics including cleft type, sex and ethnicity and (b) To compare these outcomes to similar international studies. SETTINGS AND SAMPLE POPULATION: Nation-wide prospective and retrospective cephalometric analysis of 76 patients with CUCLP and 23 patients with CBCLP pre-secondary alveolar bone graft. MATERIALS AND METHODS: Assessment was undertaken by three experienced orthodontists blinded to patient identity. A total of 13 hard tissue and 8 soft tissue landmarks were identified allowing for an assessment of 16 angular, three linear and one ratio variables. Inter-assessor reliability was determined by pre-defined measurement error thresholds. RESULTS: Inter-assessor reliability of cephalometric landmarks restricted reporting to 10 hard tissue, four soft tissue and one ratio variables. CUCLP had greater midface and mandibular retrusion than CBCLP. Females had greater midface and mandibular prominence and smaller nasal projections. The Pacific and Maori groups had more retrusive midfacial profiles, and the Pacific group had more prominent mandibles. A sub-analysis of New Zealand European CUCLP results found they were closely aligned to Eurocleft and Americleft study centres with less favourable outcomes. CONCLUSIONS: The reliability of a number of cephalometric measurements was poor. Lateral craniofacial morphology and soft tissue profile outcomes varied between CUCLP/CBCLP, sex and ethnicity. The New Zealand European outcomes are similar to or less favourable to other studies.

A preliminary investigation into the effect of the use of the Short Message Service (SMS) on patient attendance at an NHS Dental Access Centre in Scotland.

AIM: This study´s aim was to assess whether the use of Short Message Service (SMS) text reminders sent to patients prior to their dental appointments improved attendance rates for two dentists at a dental access centre in Kirkcaldy, Fife, Scotland. METHOD: Automated SMS text reminders were set up through practice management software at Kirkcaldy Dental Access Centre. Two audits, using a research methodology, were then performed. Failure to attend appointments with the two dentists at 150 consecutive appointments was assessed before and after implementing the SMS text reminders. The null hypothesis that SMS reminders do not improve attendance rates at the dental access centre was tested. The Yates´ corrected chi-square test was applied to the resulting data, with the level for statistical significance set at P<0.05. RESULTS: Patients readily accepted the text messages and found them to be non-intrusive. Failed attendance at appointments for the two dentists was reduced from 46/150 (31%) before the SMS text reminders were introduced to 21/150 (14%) after its introduction (P=0.00088). Thus the use of SMS text reminders resulted in a statistically significant reduction in the number of failed attendances at appointments for the two dentists. CONCLUSIONS: In this preliminary study, SMS appointment reminders reduced the number of failed appointments significantly. They can provide an automated, non-intrusive, and cost-effective method of improving patient attendance at dental appointments.
