Deficiencies in maxillary growth have often been implicated in suboptimal results of cleft lip and palate therapy. Cone-beam computed tomography provides an opportunity to look at the dimensions of the maxillary complex in three dimensions in a way that is not possible with lateral cephalograms or dental models. The purposes of this preliminary study were to outline a new set of 18 cone-beam computed tomographic measurements, apply them to 6 patients with unilateral cleft lip and palate (UCLP), and contrast them to a comparable sample of 7 normal young adults. The patients with UCLP were treated with a single protocol by a single surgeon and orthodontist. The 18 measurements had a mean intrarater reliability of 0.95 and ranged from 0.40 to 2.23 for the individual measurements. The mean interrater reliability was 1.01 and ranged from 0.40 to 2.45 for the individual measurements. Significant differences between the patients with UCLP and control subjects (combined sex samples) were found in palate length, anterior palate thickness, overall sagittal maxillary length, and premaxillary height (Mann-Whitney U tests, P ≤ 0.037). The body of the maxilla and its heights appear less affected. These methods and preliminary findings lay the groundwork for larger scale and prospective studies that evaluate such dimensional data in conjunction with positional data and other vital outcomes of cleft lip and palate therapy such as speech and occlusion.

ABSTRACT Objective To use an alumni-centered, practice-based research network to evaluate white spot lesions (WSLs) among treated orthodontic patients. Materials and Methods: An initial survey was conducted to ascertain whether orthodontic alumni from Texas A&M University Baylor College of Dentistry were willing to participate. Twenty randomly selected alumni participated, providing 158 treated cases. Each alumnus (1) obtained internal review board consent; (2) submitted pre- and posttreatment photographs of 10 consecutively finished cases; (3) completed a treatment survey; and (4) had the patient/parent complete the American Dental Association (ADA) Caries Risk Assessment. Results: Almost 90% of the alumni surveyed were willing to participate in the practice-based research, primarily because a fellow alumnus asked them to. Approximately 28% of the patients developed WSLs. The average patient developed 2.4 white spots, affecting 12.7% of the teeth examined. WSLs were significantly (P < .001) more (2.3−3.2 times) likely for patients who were identified on the ADA Caries Risk Assessment. The risk of developing WSLs during treatment was also increased for those with fair (2.7 times) or poor (3.5 times) oral hygiene, poor gingival health (2.3 times), and extended treatment times (2.1 times). Conclusions: There is a substantial risk of developing WSLs among private practice patients, depending partially on the length of treatment. Patients at greatest risk can be identified prior to treatment based on the ADA Caries Risk Assessment, oral hygiene, and gingival health.

Dental radiography-prescribing practices: a nationwide survey of dental hygienists.

Potential harm from ionizing radiation has led to the development of guidelines to protect patients and practitioners from unnecessary radiation exposure; however, these guidelines may or may not be followed in practice. This study surveyed US dental hygienists with regard to radiology policies in the workplace. The survey, consisting of 62 knowledge and practice items regarding use of dental radiography, was based on the 2012 publication by the American Dental Association (ADA) and the US Food and Drug Administration (FDA): Dental Radiographic Examinations: Recommendations for Patient Selection and Limiting Radiation Exposure. The survey link was emailed to 10,000 subscribers of the Dimensions of Dental Hygiene magazine and posted on the magazine's Facebook page. Five hundred seventeen dental hygienists completed the survey. Data analysis included descriptive statistics, cross-tabulations, and chi-square analyses. Approximately 45.9% of respondents reported that the dentist determined the need for radiography, and 41.8% reported that the decision was made by the dental hygienist. The majority of respondents (82.4%) reported that there were times when a clinical examination was not performed before imaging, and 69.9% reported that images had been ordered on the basis of a set time interval. Approximately 35.6% reported that images had been requested on the basis of the patient's insurance reimbursement. For adult recall patients with no clinical caries and low caries risk, general and corporate dental practices made bitewing radiographs more frequently (every 12 months) compared with educational institutions (P < 0.05). In the case of children and adolescent recall patients without caries and with low caries risk, for children, corporate dental practices made bitewing radiographs more frequently (every 6 months) than educational institutions (P < 0.05); for adolescent patients, corporate and general dental practices preferred to make bitewing images every 12 months, whereas educational institutions preferred to make bitewing images every 18 months (P < 0.05). The findings suggest that some dental practices are not strictly following the ADA/FDA guidelines with regard to frequency of radiographic exposures.
