Objective The modified Huddart and Bodenham scoring system assesses maxillary arch constriction and surgical outcomes in cleft lip and palate. This project automates modified Huddart and Bodenham scoring using three-dimensional digital models. Design Development of a novel software tool. Setting The design, construction, development, and testing of the system was carried out at Dundee Dental Hospital. Patients, Participants Subjects with cleft lip and palate. Interventions A plug-in has been developed using an open three-dimensional development platform: Rhinoceros, version 5 ( http://www.rhino3d.co.uk ). Users select cusps on mandibular and maxillary teeth on three-dimensional digital models. A three-dimensional cubic spline generates a mandibular curve, and a best-fit horizontal mandibular reference plane is produced using a least-squares method. Horizontal distances projected from the shortest three-dimensional distances were subsequently calculated between the maxillary cusps and the mandibular curve to calculate the modified Huddart and Bodenham score. Main Outcome Measures Automatic scoring of digital models using the modified Huddart and Bodenham system produces similar results to manual scoring. Results By standardizing outcome assessment in cleft care, multicenter comparisons for audit and research can be simplified, allowing centers throughout the world to upload three-dimensional digital models or intraoral scans of the dental arches for remote scoring. Thereafter, these data can feed back into the global database on orofacial clefting as part of the World Health Organization's international collaborative “Global Burden of Disease” research project for craniofacial anomalies. Conclusions The automated system facilitates quicker and more reliable outcome assessments by minimizing human errors.

Objective The aim of this study was to investigate the prevalence of caries in South Vietnamese children with a known oral cleft. Setting The children were screened at local dental hospitals in five different cities in southern Vietnam. Participants One hundred fifty-four children aged 4 to 6, 11 to 13, and 14 to 16 years old with a cleft lip, cleft palate, or both were included in the study. Outcome Measurements For every age group, clefts were divided in four types. The dmft/DMFT was specified according to criteria of the World Health Organization (1997). Results The mean number of teeth affected by caries was 9.95 for 4- to 6-year-old children, 2.97 for 11- to 13-year-old children, and 4.93 for 14- to 16-year-old children, respectively. Four- to 6-year-old children with a unilateral or bilateral cleft lip and palate had significantly more caries and a higher dmft (decayed, missing, and filled teeth index) than children of the same age with only a cleft lip or a cleft lip and alveolus. Conclusions Vietnamese children with an oral cleft have high numbers of teeth affected by dental caries, and special attention will be necessary for their oral health.

Objective The objective of this study was to determine the three-dimensional midsagittal reference planes for unilateral cleft lip and palate (UCLP) patients that can be easily applied in a clinical setting. Design This was a retrospective analysis. Patients There were 35 UCLP patients (25 men, 10 women; 28.1 ± 6.9 years old) in this study. Methods With landmark's three-dimensional coordinates obtained from cone-beam computed tomography, the symmetric midsagittal reference planes were calculated by applying the ordinary Procrustes superimposition method using the original and mirror images. Procrustes analysis was also used to find the closest landmarks to the calculated symmetric midsagittal reference plane and test its compatibility with the symmetrical midsagittal reference plane. Main Outcome Measure The three nearest landmarks to the symmetric midsagittal reference plane were Opisthion, Basion, and Nasion. Results The averages of the sums of the squared Euclidean distance and squared Procrustes distance differences between the two configurations and shapes fabricated by the symmetrical and landmark-based midsagittal reference planes, respectively, were calculated as 1.836 ± 3.295 and 1.519 × 10–5 ± 2.351 × 10–5. Conclusion It was confirmed that the midsagittal reference planes from these selected landmarks for UCLP patients were compatible with symmetric midsagittal reference planes from the Procrustes analysis and the asymmetric measurements.

Rural Access

ABSTRACTThe Indian sub-continent remains one of the most populous areas of the world with an estimated population of 1.1 billion in India alone. This yields an estimated 24.5 million births per year and the birth prevalence of clefts is somewhere between 27,000 and 33,000 clefts per year. Inequalities exist, both in access to and quality of cleft care with distinct differences in urban versus rural access and over the years the accumulation of unrepaired clefts of the lip and palate make this a significant health care problem in India. In recent years the situation has been significantly improved through the intervention of Non Governmental Organisations such as SmileTrain and Transforming Faces Worldwide participating in primary surgical repair programmes. The cause of clefts is multi factorial with both genetic and environmental input and intensive research efforts have yielded significant advances in recent years facilitated by molecular technologies in the genetic field. India has tremendous potential to contribute by virtue of improving research expertise and a population that has genetic, cultural and socio-economic diversity. In 2008, the World Health Organisation (WHO) has recognised that non-communicable diseases, including birth defects cause significant infant mortality and childhood morbidity and have included cleft lip and palate in their Global Burden of Disease (GBD) initiative. This will fuel the interest of India in birth defects registration and international efforts aimed at improving quality of care and ultimately prevention of non-syndromic clefts of the lip and palate.

Understanding patient awareness of cleft lip and/or palate (CL/P) and evaluating demand for necessary procedures may serve to better target future efforts in global outreach. We utilized internet search query data from Google Trends for the terms: “cleft lip,” “cleft palate,” “cleft lip and palate,” “cleft surgery,” and “cleft repair” from January 2004 to January 2021. Relative search volumes (RSV) recorded for the top 5 highest displaying countries and top 3 available regions within those countries were compared against global outreach by Operation Smile and Smile Train, as measured by the number of patients treated. World Health Organization (WHO) indicators were used to validate the RSV values for each country and better understand the current infrastructure and need for cleft care in those countries. Globally, there was an increase in RSV for the terms “cleft lip,” “cleft palate,” “cleft repair,” and “cleft surgery” between 2004 and 2021. For “cleft lip,” the countries with the highest displaying RSVs included: Ghana (100%), Zimbabwe (97%), Nepal (78%), the Philippines (64%), and Kenya (52%). Countries with high RSVs and moderate to high WHO indicators included Ghana, Kenya, India, Nigeria, and Zimbabwe. Countries with high RSVs and poor WHO indicators included Nepal and Pakistan. Some countries had specific regions with high search demand that are not currently targeted for global outreach. Using Google Trends’ data may help find more feasible locations and targeted care for efforts in global outreach with better patient awareness and turnout where demand for CL/P is increasing.
