Objectives:
The objectives of the study were to compare the skeletal, dentoalveolar, and periodontal changes between two types of microimplant-assisted rapid maxillary expansion appliances: The bone-anchored maxillary expanders (BAME) and the tooth-bone-anchored maxillary skeletal expander (MSE).
Materials and Methods:
Thirty-four patients with a transverse maxillary deficiency were divided into two groups; the first group (16 patients, average age 14.9 years) was treated with the MSE appliance, and the second group (18 patients, average age 13.8 years) was treated with the BAME appliance. Cone-beam computed tomography scans were taken at pre-treatment (T1) and immediately post-expansion (T2) to measure the changes in midpalatal suture opening, total expansion (TE), alveolar bone bending, dental tipping (DT), and buccal bone thickness. Data were analyzed using paired t-test and two-sample t-test.
Results:
Midpalatal suture separation was found in 100% of the patients in both groups. The TE at the first molar was 5.9 mm in the MSE group and 4.7 mm in the BAME group. The skeletal contributions were 56% and 83% of TE for the MSE and BAME groups, respectively. Significantly less dental buccal tipping and buccal bone loss were found with the BAME group. The midpalatal suture in both groups exhibited a parallel opening pattern in the axial plane.
Conclusion:
The use of BAME appliance resulted in greater skeletal effects, less dental tipping, and less buccal bone reduction compared to MSE appliance (immediately after maxillary expansion).
Heart disease is the number one killer of women, and studies have shown connections between cardiovascular and oral health. However, interprofessional community-based participatory initiatives promoting women's oral health have received little research attention. This study evaluated the effectiveness of personalized oral health education (POHE) during a free one-day interprofessional women's health promotion event. The objectives were to 1) assess the participants' knowledge about the connection between oral health and heart disease; 2) disseminate information about oral-systemic linkages; 3) encourage comprehensive dental examinations; and 4) evaluate POHE outcomes. West Virginia University School of Dentistry faculty and students delivered POHE to the participants. These POHE instructors were calibrated with a standardized script regarding periodontal disease, health impact of tobacco, xerostomia-inducing medications, and oral hygiene instruction. Immediately prior to and following each POHE session, all the participants (N=165; 100 percent response rate) completed a number-coded questionnaire. The indings showed that the participants' knowledge of oral-systemic health linkages had increased following the POHE. The respondents received oral health kits and were offered discount vouchers toward the cost of a comprehensive oral examination at the dental school. This replicable model may prove useful to other dental schools in promoting women's oral health.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
