A systematic scoring system to determine the long-term prognosis for severely damaged teeth
Mahdi Kadkhodazadeh
Reza Amid
This article introduces a quantitative systematic risk assessment scoring system to determine the long-term prognosis for severely damaged teeth based on 5 factors: crown to root ratio, root condition, risk of furcation involvement, final restoration complexity, and esthetic results. This system is intended to simplify and organize the decision-making process and facilitate communication with patients.

Digital intraoral imaging: analysis of retakes and reduction in radiation exposure using rectangular collimation
Suvendra Vijayan
Nilesh Shah
Anitha Potluri
This study evaluated the number of retakes needed when dental students switched from using round collimators to rectangular collimators for digital intraoral imaging. The use of rectangular collimators resulted in an initial increase in retakes, mostly due to placement errors; however, it also resulted in a significant reduction in radiation exposure, and retake rates normalized as students gained experience.

A retrospective pilot study found that a machine learning model was able to differentiate between benign and oral potentially malignant lesions with a mean classification accuracy of 70%, sensitivity of 80%, and specificity of 60% when grayscale and enhanced color intraoral images were used, suggesting that machine learning may be a promising tool for identification of oral potentially malignant disorders.

Nicolaas C. Geurs
This study retrospectively evaluated associations between periodontal disease parameters and body mass index (BMI) in 418 treated periodontitis patients undergoing periodontal maintenance therapy. The analysis revealed that BMI was associated with age and missing teeth, and obese status was associated with a significantly higher number of sites with bleeding on probing.

In a study evaluating the association between dental erosion (DE) and gastroesophageal reflux disease (GERD) in 80 patients, the extent of DE was found to be positively associated with GERD symptoms. In some patients, DE was the only clinical indication of untreated or undertreated GERD. Dentists should consider referring patients with DE to physicians to ensure that systemic conditions are identified.

Frank Lippert
Evaluation of fluoride and calcium concentrations in drinking water from public water fountains on a university campus revealed that fluoride concentrations were within the optimal range recommended by the US Public Health Service, and calcium concentrations were consistent with those reported in previous surveillance studies.

Cleverson Luciano Trento
Comparison of the microgap sizes at the interfaces between Morse taper implants and straight or angled abutments revealed that, overall, there were no statistically significant differences between the groups. However, the angled abutments showed greater sealing ability, as the mean value of the largest microgap was 1.43 µm compared with 1.64 µm in the straight abutment group.

Nasal airway obstruction and orofacial pain: a multicenter retrospective analysis
Steven R. Olmos
In a retrospective study investigating the relationship between nasal airway obstruction and symptoms of orofacial pain, nasal valve compromise was the most prevalent type of nasal airway obstruction found in the study population of 1393 patients. Nasal valve compromise showed a statistically significant comorbidity with capsulitis as well as facial and cervical myositis.

This case report documents pemphigus vulgaris in an atypical patient, a 23-year-old woman with concomitant celiac disease. The patient was treated with systemic rituximab, which resulted in rapid improvement of the cutaneous lesions but only gradual improvement of the oral lesions after 2 infusions.

Suman Challa
Associations between malpractice allegations and the severity of the alleged malpractice injury were studied using information from the National Practitioner Data Bank from 2010 through 2020. The highest number of allegations was in the treatment-related allegations group, and the confounding variable graduation year had significant associations with major temporary and minor permanent injury.
