Altered Prevalence of Pulp Diagnoses in Diabetes Mellitus Patients: A Retrospective Study.

INTRODUCTION: Diabetes mellitus (DM) is a complex multisystemic disorder that affects an estimated 21 million Americans. No studies have evaluated the association of DM with the prevalence of each pulpal diagnosis. The objective of this study was to compare the prevalence of each pulp diagnosis including symptomatic irreversible pulpitis (SIP), asymptomatic irreversible pulpitis, reversible pulpitis, normal pulp, and pulp necrosis (PN) in DM patients against a nondiabetic control group. METHODS: A retrospective chart review was approved by Rutgers University Institutional Review Board. The prevalence of the diagnoses SIP, asymptomatic irreversible pulpitis, reversible pulpitis, normal pulp, and PN was calculated from AxiUm (Exan software, Las Vegas, NV) electronic health records at Rutgers School of Dental Medicine. The chi-square test was used to see the relationship between the 2 categoric variables. Second, binary logistic regression analyses were performed for each group. RESULTS: A total of 2979 teeth were diagnosed with a pulp condition between April 2013 and November 2018. The total tooth number of DM patients was 682, whereas the tooth number of nondiabetic patients was 2297. In the subgroup of patients younger than 40 years old, SIP was notably more prevalent in DM patients. In addition, the prevalence of PN in elderly DM patients (60-69 years old) was significantly higher than in the control group. CONCLUSIONS: The prevalence of SIP in DM patients was significantly higher compared with the control group (<40 years old), suggesting the possibility that DM could hypersensitize the subgroup of patients younger than 40 years old to pulpitis pain.

Factors Associated with Incomplete Endodontic Care.

INTRODUCTION: Incomplete endodontic treatment has been associated with detrimental health outcomes. METHODS: This retrospective study reviewed charts of patients receiving endodontic care over a 1-year period at the Postgraduate Endodontic Clinic at Rutgers School of Dental Medicine, Newark, NJ, to assess whether factors such as receipt of palliative endodontic care and demographic factors were associated with completion, or noncompletion, of initial nonsurgical root canal therapy (RCT). RESULTS: A total of 1806 patient charts met the study inclusion criteria. With descriptive statistics and bivariate analysis, the variables of palliative care, Medicaid recipient, age group, and distance from the clinic were significantly associated with RCT completion (P < .05). In the binary logistic regression with all independent variables, palliative care and age group variables were the significant factors (P < .05). Patients who had no palliative care had 8.5 times the odds of completing RCT than patients who had received palliative care. The age group of 18-35 years had 0.59 times the odds of complete RCT than the age group <18 years. CONCLUSIONS: Incomplete nonsurgical endodontic treatment is highly associated with the receipt of prior palliative care. Further research is indicated to investigate additional factors that may influence patient completion of endodontic care and opportunities to improve public health care program design to obtain optimal patient-centered outcomes.

Dental Abscess to Septic Shock: A Case Report and Literature Review.

Sepsis is a leading cause of death in the United States, with a mortality rate in excess of 215,000 deaths per year. It may lead to septic shock, a complex pathophysiological process with microbial and host response events that progress to multisystem derangement. There is poor documentation of the relationship between dental infection and septic shock, with only a few case reports of septic shock secondary to dentoalveolar abscess. Presented is a case of sepsis/septic shock in a 23-year-old man with signs and symptoms of pulpal necrosis, acute apical abscess, and canine space infection that rapidly progressed to an altered mental state, hyperthermia, tachycardia, hypotension, acute respiratory failure, diarrhea, renal insufficiency, lactic acidosis, leukocytosis, and hyperglycemia. Once septic shock develops, the mortality rate is nearly 50%. Early antimicrobial intervention is associated with surviving severe sepsis, making it critical for dentists to understand local factors leading to the crisis and the signs and symptoms of the sepsis-septic shock continuum.

Chamberless Endodontic Access for Treatment of Calcified Anterior Central Incisors.

INTRODUCTION: Modern techniques for treating maxillary anterior central incisors with calcified canals emphasize maintaining coronal dentin with small crown access. Alternatively, traditional retrograde surgical procedures are focused on creating an apical seal predominately limited to the remaining resected apical one third of the root canal space. A treatment option for calcified anterior teeth, with avoidance of traditional orthograde access, is presented. Chamberless endodontic access (CEA) to the canal is chosen in this case, leveraging a previous surgical treatment and osseous defect to create straight line canal access. METHODS: A tooth presenting with a chronic apical abscess and an apparent previous apical surgery was instrumented and obturated using a CEA avoiding the traditional orthograde approach to the root canal system. Straight line approach was achieved retrograde and canal instrumentation was performed using ultrasonic activated U-files. Canal obturation was accomplished with warm vertical condensation technique followed by placement of an apical retroseal. RESULTS: A successful 52-month outcome demonstrated the viability of CEA facilitating retrograde instrumentation and obturation. CONCLUSIONS: Use of CEA simultaneously protected the clinical crown and provided a successful clinical outcome. A viable option for treatment of an anterior calcified canal and abscess due to dental trauma, CEA mitigates many of the risks associated with the treatment of calcified root anatomy.

Comparison of sealing ability of MTA and EndoSequence Bioceramic Root Repair Material: a bacterial leakage study.

OBJECTIVE: To compare the sealing ability of ProRoot mineral trioxide aggregate (MTA) to the sealing ability of EndoSequence Bioceramic Root Repair Material (ES-BCRR) putty using a bacterial leakage model. METHOD AND MATERIALS: Root canals of 60 single-rooted extracted teeth were enlarged to an apical diameter of 0.5 mm using EndoSequence files. The apical 3 mm of each root was sectioned at 90 degrees to the long axis of the root. An ultrasonic surgical tip was used to prepare a 3-mm deep root-end preparation in all teeth. Teeth were equally divided into four groups: Group 1, MTA; Group 2, ES-BCRR putty; Group 3, positive control, gutta-percha without sealer; Group 4, negative control, sealed with wax and nail varnish. Prepared teeth were kept moist for 48 hours to allow for initial setting of the materials. After ethylene oxide sterilization, the teeth were suspended in sterilized vials containing 3% phenol lactose broth and inoculated with Enterococcus faecalis through the occlusal access openings. The samples were observed daily for leakage to a maximum of 28 days. Chi-square and Fisher exact tests were used to compare the experimental groups and an alpha level of significance was set at P = .05. RESULTS: In the ES-BCRR group 93% of samples leaked, compared to only 20% of samples in the MTA group. There was a significant difference in leakage between the experimental groups (P < .0001). Also there were no significant differences between the negative control group and MTA group and between the positive control group and ES-BCRR group (P = 1.00). CONCLUSION: Samples in the ES-BCRR group leaked significantly more than samples in the MTA group.
