Incidental Findings in Small Field of View Cone-beam Computed Tomography Scans, Part 2: Interpretation with Aid of a Checklist.

INTRODUCTION: Cone-beam computed tomography (CBCT) scans are routinely used by endodontic residents and faculty at Tufts University School of Dental Medicine for diagnostic purposes but are not routinely read for pathologic findings by a radiologist. In a 2017 study by Oser et al (part 1), endodontic residents and a radiologist interpreted CBCT scans taken for endodontic diagnostic purposes, and their findings were compared. The results demonstrated that a radiologist is significantly more likely to report incidental findings in small field of view (FOV) scans. A limitation of this study was that the radiologist used a checklist of common findings to review the scans. The purpose of this study was to examine whether the use of a checklist would improve the sensitivity of the endodontic residents' reporting of incidental findings in small FOV CBCT scans. METHODS: The 203 small FOV CBCT scans used in part 1 were obtained and reviewed by endodontic residents in a systematic fashion. Radiographic findings were reported using a blank checklist. The results were compared with those previously reported. RESULTS: The radiologist reported abnormalities in 176 of the 203 subjects (87%), and the residents reported abnormalities in 184 of the 203 subjects (91%). There was an increase in false positive findings when the residents were using a checklist. CONCLUSIONS: The use of a checklist improved the sensitivity but decreased the specificity of the reporting of incidental findings in small FOV CBCT scans by endodontic residents.

Ingrowth of Mineralized Tissue into the Root Canal of Immature Permanent Teeth after a Traumatic Injury: A Report of 3 Cases.

The aim of this case series was to describe the endodontic management of 3 immature permanent teeth that sustained traumatic injuries and subsequently presented with complete ingrowth of mineralized tissue into the canal space. Ingrowth of bone/mineralized tissue into the canal has been considered a poor long-term outcome with an inherent risk of ankylosis. In cases 1 and 2, no endodontic treatment was undertaken, except for emergency management requiring splinting. The cases were followed for 36 and 23 months, respectively. No ankylosis was evident over the review period, and normal teeth eruption was apparent. In case 1, the tooth was treated orthodontically and was responsive to pulp sensibility testing. In both cases, there was an appearance of an internal periodontal ligament-like space on the inner root wall of the canal. In case 3, 2 years postinjury, pulp necrosis and apical periodontitis occurred, and the tooth was managed with regenerative endodontic treatment consistent with the European Society of Endodontology and the American Association of Endodontists guidelines/recommendations for a regenerative procedure. The case was followed for 8 years after regenerative endodontic treatment. No ankylosis was noted with normal eruption of the teeth. The tooth was responsive to pulp sensibility testing despite the ingrowth of mineralized tissue, which was confirmed clinically.

Dental Hygienist-Led Chronic Disease Management System to Control Early Childhood Caries.

UNLABELLED: Management of the complex chronic disease of early childhood caries requires a system of coordinated health care interventions which can be led by a dental hygienist and where patient self-care efforts are paramount. BACKGROUND AND PURPOSE: Even after receiving costly surgical treatment under general anesthesia in the operating room, many children develop new and recurrent caries after only 6-12 months, a sequela that can be prevented. This article describes the chronic disease management (CDM) of dental caries, a science-based approach that can prevent and control caries. METHODS: In this article, we (1) introduce the concept of CDM of dental caries, (2) provide evidence that CDM improves oral health outcomes, and (3) propose a dental hygienist-led team-based oral health care approach to CDM. Although we will be describing the CDM approach for early childhood caries, CDM of caries is applicable in children, adolescents, and adults. CONCLUSIONS: Early childhood caries disease control requires meaningful engagement of patients and parents by the oral health care team to assist them with making behavioral changes in the unique context of their families and communities. The traditional dentist/hygienist/assistant model needs to evolve to a collaborative partnership between care providers and patients/families. This partnership will be focused on systematic risk assessment and behaviorally based management of the disease itself, with sensitivity toward the familial environment. Early pilot study results demonstrate reductions in the rates of new caries, dental pain, and referral to the operating room compared with baseline rates. Dental hygienists are the appropriate team members to lead this approach because of their expertise in behavior change and prevention.
