Retrospective CBCT analysis of airway volume changes after bone-borne vs tooth-borne rapid maxillary expansion.

Objectives: To compare changes in upper airway volume after maxillary expansion with bone- and tooth-borne appliances in adolescents and to evaluate the dentoskeletal effects of each expansion modality.

Materials And Methods: This retrospective study included 36 adolescents who had bilateral maxillary crossbite and received bone-borne maxillary expansion (average age: 14.7 years) or tooth-borne maxillary expansion (average age: 14.

Associations of fluoride intake with children's cortical bone mineral and strength measures at age 11.

Objectives: There is strong affinity between fluoride and calcium, and mineralized tissues. Investigations of fluoride and bone health during childhood and adolescence show inconsistent results. This analysis assessed associations between period-specific and cumulative fluoride intakes from birth to age 11, and age 11 cortical bone measures obtained using peripheral quantitative computed tomography (pQCT) of the radius and tibia (n = 424).

MALOCCLUSION, PAST ORTHODONTIC TREATMENT, AND SATISFACTION WITH DENTAL APPEARANCE AMONG CANADIAN ADULTS.

Objective: To examine whether malocclusion and past orthodontic treatment are associated with satisfaction with dental appearance among Canadian adults.

Methods: Using data from the 2007-09 Canadian Health Measures Survey, this cross-sectional study analyzed information from 2184 respondents (1005 men and 1179 women) aged 20-59 years. The outcome variable was satisfaction with dental appearance.

Time until first dental caries for young children first seen in Federally Qualified Health Centers: a retrospective cohort study.

Objectives: The study assessed the time until first dental caries for young children seen at five Federally Qualified Health Centers (FQHC) in Iowa and the relationship with the frequency and gaps (in months) of dental episodes, the number of topical fluoride treatments, and the number of dentists caring for the subject.

Methods: Forty children were randomly selected at each FQHC (n = 200). All children were continuously enrolled in the Medicaid program and had their first dental visit prior to age 6.

General dentist characteristics associated with rural practice location.

Purpose: To examine whether there is a difference in the likelihood that a general dentist practices in a rural location based on individual characteristics, including dental school attended, birth state, practice arrangement, sex, and age.

Methods: All private practice, general dentists in Iowa were included in this study. Data were extracted from the year 2010 version of the Iowa Dentist Tracking System, which monitors practice patterns of active dentists.

Periodicity of dental recall visits for young children first seen in community health centers.

Objectives: To study the factors associated with young children who had their first dental visit (FDV) at a Federally Qualified Health Center (FQHC) and returned within 12 months for a second dental episode.

Methods: Two hundred Medicaid-enrolled children who were less than 6 years old were randomly selected from five Iowa FQHCs. Dental utilization was followed for 36 months using dental charts and Medicaid medical and dental claims data, regardless of provider.

Comparison of dental esthetic perceptions of young adolescents and their parents.

Objectives: To compare dental esthetic perceptions of adolescents at age 13 with those of parents and to assess associations with dental fluorosis.

Methods: Adolescents aged 13 underwent dental examinations for fluorosis on maxillary anterior teeth using the Fluorosis Risk Index. Adolescents and parents completed questionnaires concerning satisfaction with adolescents' dental appearance.
