A study model based photographic method for assessment of surgical treatment outcome in unilateral cleft lip and palate patients

Abstract

The aim of this study was to test the reliability of using digital photographs of study models as an alternative to the use of plaster study models in the assessment of surgical treatment outcome in 5-year-old children with unilateral cleft lip and palate (UCLP). Fifty-six dental study models available from the Managed Clinical Network for Cleft Services in Scotland (CLEFTSiS) database of patients aged 5-years with non-syndromic UCLP were employed. An experienced examiner scored the plaster study models using the modified Huddart/Bodenham system. A set of digital photographs stored in the CLEFTSiS electronic patient record database of five different views of the same study models were scored by three examiners to allow calculation of interexaminer reliability. The same examiners repeated the scoring 1 month later under similar conditions to determine intraexaminer reliability and minimize the influence of memory bias on the results. The mean kappa value for the application of the modified Huddart/Bodenham system on photographs of 5-year-old UCLP study models was 0.65 +/- 0.05. The mean kappa value for the measurement of overjet on the digital photographs was 0.68 +/- 0.07. Using the interpretation suggested by Altman, good agreement for both scoring systems was found. Therefore, digital photographs of study models are a reliable alternative to measuring treatment outcome using study models of 5-year-old children with UCLP.

Intraoral 3D Scanning or Dental Impressions for the Assessment of Dental Arch Relationships in Cleft Care: Which is Superior?

“…These results are in line with previous cleft care studies which have determined “Good” to “Very Good” levels Altman, 1991) of intra- and interobserver agreement for plaster models with photographs Nollet et al, 2005; Ali et al, 2006; Liao et al, 2009; McAuliffe et al, 2010) and plaster models with digital models (Asquith and McIntyre, 2012; Leenarts et al, 2012; Servet et al, 2012; Chawla et al, 2013) (Tables 1 and 2). Our investigation was novel by employing intraoral 3D scanning, as such models have not been investigated for the assessment of dental arch relationships in cleft care to date.…”

Treatment Outcome of Bangladeshi UCLP Patients Based on Both Phenotype and Postnatal Treatment Factors using Modified Huddart Bodenham (mHB) Index

“…A very few studies have been done using the mHB index. Among them, most of the studies (Ali et al, 2006; Wangsrimongkol and Jansawang, 2010; Manosudprasit et al, 2011; Dobbyn et al, 2012; Dobbyn et al, 2013) are about the reliability and validity of this index. It can be noted that Kappa value of mHB in this study also has been shown very good intra- and interexaminer agreements, as in previous studies (Table 1).…”

Three-Dimensional Digital Models for Rating Dental Arch Relationships in Unilateral Cleft Lip and Palate

“…Traditionally, the 5-year-olds’ index is applied to plaster models, but the potential challenges of physical models, such as the inconvenience of transportation and the risk of damage, have led to investigations into alternative mediums. The use of digital photographs of plaster models (Nollet et al, 2004; Ali et al, 2006) and intraoral clinical photographs (Liao et al, 2009; McAuliffe et al, 2011) have been shown to be reliable alternatives.…”
