711THE RELATIONSHIP BETWEEN ERUPTION PATTERN AND CELIAC DISEASE IN JORDANIAN CHILDREN AND ADOLESCENTSObjective to determine the relationship between eruption pattern of deciduous and permanent teeth in children and adolescents with celiac disease and to compare their findings with healthy group and gender matched children and adolescents. A total of 45 patients out of 86. Twenty three patients with celiac disease who were regular attendants to the pediatric gastrointestinal clinics and 22 healthy dental patients who attended the pediatric dental practice clinic at King Hussein Med ical Center and Queen Rania Alabdallah Hospital for children, all were with mixed dentition and selected to match the prospective study group by age and gender. Both study and control groups were examined for the number of erupting deciduous and permanent teeth (excluding third molars) using the chronological tables of the development of permanent dentition. Delayed eruption was considered when the teeth were not in arch after 6 months of their normal dental age of eruption . In each of the study and control groups, there was 27 females (60.5%) and 18 (39.5 %) males. The mean age was 13.22±2.85 years for the study group and 13.35±2.74 years for the control group. The results showed that patients with mixed dentition and incomplete eruption of permanent teeth in the study vs. control groups account for 23(51.1 %) vs. 22(48.9%) with the mean age of 12.4 vs. 11.8 years respectively. Deciduous teeth were greater in celiac than control group comprise 137 (24.6%) vs. 84 (16%), while permanent teeth were less in celiac patients comprise 419 (75.4%) vs. 441(84%). The mean value of the delay eruption in the study group was 0.52 vs. 0.15 in the control group, with the P value of 0.010. Un -erupted and partially erupted permanent teeth comprise of 95 teeth for the study group compared with 64 teeth for the control group . The celiac group showed statistically significant delay in the eruption pattern compared with the control groupmal_far@hotmail.comResearch712016Eruption pattern,Relationship,Celiac disease,Mixed dentitionMaan Yacoub Alfar,Sami Eid Jebreen,Abdallah Majed Ghanma,Rania Abdalla Al Saddi,Reem Hani Dababneh,Yassin Mohamed TawarahSenior Specialist in Paediatric Dentistry, Queen Rania AlAbdallah Hospital for Children, Royal Medical Services, Amman, Jordan,Consultant in Prosthodotics, Director of Dental Corps, Jordan,Cosultant in Paediatric Gastrointology, , Queen Rania AlAbdallah Hospital for Children, Royal Medical Services, Amman, Jordan,Specialist in Conservative Dentistry, King Hussein Medical Center, Royal Medical Services, Amman, Jordan,Senior Consultant in Periodontology, King Hussein Medical Center, Royal Medical Services, Amman, Jordan,Consultant in Biostatistics Department, King Hussein Medical Center, Royal Medical Services, Amman, Jordan
