Buccolingual Inclination of Second Molars in Untreated Adolescents and Adults with Near Normal Occlusion: A CBCT Study.

The mandibular second molars are lingually positioned relative to the alveolar ridge and have a limited amount of lingual alveolar bony support. As the maxillary second molars are articulated with the mandibular second molars, maintaining the normal buccolingual inclination of both maxillary and mandibular second molars would potentially help to not only optimize the masticatory function, but also avoid dehiscence and fenestration. The current study evaluated the buccolingual inclination of second molars in untreated adolescents and adults. One hundred and two Caucasian subjects with skeletal class I and minimum dental arch crowding/spacing were selected and divided into two groups: (1) adolescent group: age 12-18 years, N = 51 (21 females, 30 males); (2) adult group: age 19-65 years, N = 51 (40 females, 11 males). For each subject, the inclination for each second molar was measured as the angle between the long axis of each tooth and a vertical line on cone beam computed tomography images. The Mann-Whitney U test was used for intergroup comparisons. Maxillary second molars exhibited a buccal inclination of 15.30° in the adolescent group and 15.70° in the adult group. Mandibular second molars exhibited a lingual inclination of 17.05° in the adolescent group and 15.20° in the adult group. No statistically significant differences were detected between the age groups. In addition, a statistically significant difference was only found between genders in the adolescent group for the maxillary second molar inclination. In summary, maxillary second molars exhibited buccal inclination and mandibular second molars exhibited lingual inclination. The amount of buccolingual inclination of the second molars was similar in the adolescent and adult groups.

Evaluation of diagnostic radiology acumen between 2 groups of clinical dental students.

PURPOSE: To evaluate and distinguish if an additional year of clinical experience increases the cognitive ability of dental students to accurately assess and interpret dental radiographs. METHODS: Radiological acuity was assessed between two groups of clinical dental students at Penn Dental Medicine (PDM). Group 1 was composed of 147 third-year dental students (D3), group 2 was composed of 145 fourth-year dental students (D4). A 65-question test comprising the length and breadth of radiographic anatomy and pathology was administered to both D3 and D4 students. The test was designed to test the participants' knowledge of radiographic technique, anatomy, and differential diagnosis. The null hypothesis was that there would be no significant differences between the two groups. RESULTS: STATA 15 software (StataCorp LLC, College Station, TX, USA) was used to statistically analyze the findings. Although, the mean correct score for group 1 was higher (60/65) than group 2 (59/65), there was no statistically significant difference between the performance of the groups. On average, group 1 outperformed the clinically more experienced group 2 on an individual question basis. The average overall number of correctly answered items compared to incorrectly answered items reflected this difference. CONCLUSION(S): An additional year of clinical dental education does not appear to correlate with any higher radiographic acumen. This may be due to tapering exposure to unique pathology and findings, as more routine findings are encountered daily and classroom instruction during the fourth year of dental school is limited. Early incorporation of new radiographic education tools that are clinically oriented may be one method to increase retention of knowledge accumulated in the initial didactic years of dental education.

An oral health baseline of need at a predominantly African American Program of All-Inclusive Care for the Elderly (PACE): Opportunities for dental-nursing collaboration.

This descriptive study sought to establish an oral health baseline of need for enrollees at a Program of All-Inclusive Care for the Elderly (PACE) and identify opportunities for nursing interventions. The Oral Health Assessment Tool (OHAT) was applied to a random sample of 120 enrollees, 64 of whom met inclusion criteria, agreed to participate to assess their oral health status, and were included in the analysis. The mean OHAT score was 4.4 (SD = 2.6; range 0-12). Higher scores indicate poorer oral health. The oral conditions found needing the most attention were gums, saliva, natural teeth, dentures, and oral cleanliness. Oral cleanliness scored the worst on the OHAT, highlighting opportunities for nursing interventions and the necessity for oral hygiene routines. This study also identifies the need for nurses to address enrollees' oral health and relay information back to the PACE interdisciplinary team (IDT) to initiate referrals to the dentist as needed.
