Variation of OXIS contact areas in primary molars among 3–6-year-old children with intraoral digital scanning

Purpose To determine the variation of OXIS contact areas in primary molars using digital impressions generated from an intraoral scanner (IOS). Methods A cross-sectional study was carried out on 214 caries-free posterior quadrants of 80 children (38 males and 42 females) aged 3–6 years. Calibration...

Description
Summary:Purpose To determine the variation of OXIS contact areas in primary molars using digital impressions generated from an intraoral scanner (IOS). Methods A cross-sectional study was carried out on 214 caries-free posterior quadrants of 80 children (38 males and 42 females) aged 3–6 years. Calibration of taking digital impressions with the IOS procedure was performed initially through scanning of ten quadrants of children to provide a learning environment to the examiner. The digital impressions were then exported, and the type of interproximal contact areas present between the distal surface of the primary first molar and the mesial surface of the primary second molar were identified according to the OXIS classification. The prevalence of the types of OXIS contact areas was expressed in the form of numbers and percentages. The chi-square test was applied to investigate the variability among the arches and to understand the association of OXIS contact areas across age, gender, and arches. Results The most common contact area type observed was I-type (59.8%), followed by S-type (15.4%), X-type (12.6%), and O-type (12.2%). The I-type contact area was most frequently seen in both males (51.6%) and females (65.5%), while the S-type contact area in males (14.7%) and X-type contact area in females (8.4% each) were the least frequent with no statistical significance between genders ( p  > 0.05). All three age groups studied showed the highest prevalence of the I-type contact area, which increased with an increase in age ( p
