title: Evaluation of Dental Status of Adolescents at Kuwait University Dental Clinic.
abstract: OBJECTIVE
  This study was designed to evaluate the dental status of adolescents initially presenting at Kuwait University Dental Clinic (KUDC). The purpose of this cross-sectional study was to evaluate (a) the prevalence of unrestored caries dentin among 12- to 16-year-old Kuwaiti residents, (b) the frequency of restorations extending into the inner half of the dentin, and (c) tooth loss pattern among this age group.
  
  
  METHODS
  Twelve- to 16-year-old patients who attended KUDC during the period January 2009 to December 2012 were included in this study. The total number of patients included in the study was 486; however, only 409 panoramic radiographs were available for evaluation. The Student t-test and one-way ANOVA were used for statistical analysis.
  
  
  RESULTS
  The prevalence of unrestored dentin caries among 12- to 16-year-old patients was 52%. The frequency of deep restorations extending into the inner half of the dentin was 33%. Tooth loss was found in 8.0% of the sampled population. The most common missing tooth was the mandibular first molar followed by the mandibular second premolar and the maxillary first molar. There were no statistical differences between Kuwaiti and non-Kuwaiti residents regardless of gender; however, males had a slightly higher DMFT. The DMFT and DMFS values in this study were higher than in other studies.
  
  
  CONCLUSIONS
  Despite the tremendous effort by the Kuwaiti government to improve oral health, comprehensive preventive strategies, dental treatment and maintenance of oral health are still necessary and must be reinforced in this age group.
