Association of Radiographically Diagnosed Apical Periodontitis and Cardiovascular Disease: A Hospital Records-based Study.

INTRODUCTION: Numerous studies have demonstrated an association between oral health status and systemic diseases. However, reports examining apical periodontitis (AP) and cardiovascular disease (CVD) are few. This study investigates whether an association exists between AP and CVD. METHODS: The present study was a pair-matched, cross-sectional design that used medical and dental chart review. The AP group (n = 182) was defined as subjects with radiographic AP, and the non-AP group (n = 182) was defined as subjects without any radiographic AP. Samples for both groups were pair-matched by age and gender. Diagnosis for CVD, hypercholesterolemia, hypertension, and diabetes were identified by using International Classification of Diseases, Ninth Revision, Clinical Modification and collected from electronic medical records. Documentation of alcohol use, smoking, race, and body mass index within the electronic medical records was also collected. Presence or absence of AP, missing teeth, teeth with root canal treatment, caries experience, and history of periodontal disease were collected from the electronic dental records. Analysis was performed by using Pearson χ(2), the paired t test, and conditional multivariate logistic regression. RESULTS: AP was significantly associated with CVD, hypercholesterolemia, race, missing teeth, caries experience, and number of root canal treatments in our bivariate analysis. Our final adjusted conditional logistic regression model showed statistically significant positive associations between AP and CVD (odds ratio, 5.3; 95% confidence interval, 1.5-18.4). CONCLUSIONS: Subjects with AP were more likely to have CVD than subjects without AP by 5.3-fold. However, further research is needed to elucidate temporality and reinforce association between CVD and AP.

Treatment planning considerations in older adults.

The older patient often presents with clinically challenging dental problems combined with complex medical, social, psychological, and financial barriers to oral health. Through careful consideration, the clinician can design a thoughtfully sequenced treatment plan that addresses dental conditions and facilitates improved oral health. Several models serve to guide the clinician with this endeavor. Treatment planning for a medically complex patient with xerostomia and dementia involves a great deal of uncertainty, which may be attenuated by flexibility and good communication with the patient and all involved parties.

Orbital, mediastinal, and cervicofacial subcutaneous emphysema after endodontic retreatment of a mandibular premolar: a case report.

INTRODUCTION: Subcutaneous emphysema (SCE) rarely occurs from endodontic treatment. Most reported cases of iatrogenic SCE occur in the cervicofacial region. Only a few cases have been reported of SCE extending into the mediastinum or orbital spaces. In the present report, we describe a concomitant occurrence of orbital, mediastinal, and cervicofacial SCE immediately after endodontic retreatment. METHODS: A 33-year-old woman presented to the hospital with acute swelling of the right side of her face and neck. Earlier in the day, she began experiencing rapid swelling while undergoing endodontic retreatment of a mandibular right first premolar by her general dentist. The dentist immediately referred the case to an oral surgeon who then ordered additional tests and radiographic studies at the hospital. From there, the patient received consultation and comprehensive treatment by a multidisciplinary team of medical and dental staff. RESULTS: Physical examination, laboratory tests, and computed tomographic studies confirmed a diagnosis of SCE. Extensive air pockets were detected within the orbital, mediastinum, and cervicofacial spaces. The patient was admitted to the hospital and underwent treatment and observation for massive SCE with likely secondary infection. On the fifth day, she was discharged after showing dramatic improvement. CONCLUSIONS: SCE may go undetected or misdiagnosed. Complications may be fatal. Therefore, clinicians should apply preventive measures and know how to identify and manage SCE. We review reports of SCE in the last century, discuss etiology and differential diagnosis, and present recommendations for prevention and management of SCE.
