SUBJECTS AND METHODS: SHIP is a complexly structured, population-based cross-sectional study of adults in the German region of Pomerania (age group covered: 20-79 years). Findings in a population subgroup (age group 20-49 years; n = 1777; 53.1% @entity1 ; 46.9% @entity1 ) were subjected to orthodontic evaluation. Graduated registration of anterior crowding, @entity2632 , frontal @entity2632 and sagittal intermaxillary relationship of the posterior teeth; registration of ectopic @entity235 , posterior crowding, anterior and posterior crossbite, negative @entity2632 , retroclination of the upper incisors, @entity18521 , and lateral open bite. The prevalence of almost regular dentition and of symptoms of @entity3232 as well as the frequency of orthodontic treatment (subjective @entity1 data) undergone by @entity1 and @entity1 were recorded. The correlation between the registered symptoms of @entity3232 was calculated. RESULTS: 92.2% of the subjects had symptoms of @entity3232 varying in number and severity. An anatomically correct dentition was found in only 7.8% of cases, and an "almost regular dentition" (inclusion criteria defined) in 14.2%. 32.8% of the subjects had severe @entity3232 (inclusion criteria defined). The most frequent symptoms were anterior crowding, @entity2632 , and distoclusion. These symptoms were significantly more frequent in @entity1 , while spacing and edge-to-edge bite, excessive @entity2632 and mesioclusion were more frequent in @entity1 . 26.7% of the probands (28.0% @entity1 , 25.3% @entity1 ) reported having received orthodontic treatment. The prevalence of @entity2122 ( @entity3384 , syndromes) was 0.09% in @entity1 and 0.2% in @entity1 . Increased @entity2632 was most frequently correlated with other symptoms of @entity3232 .
