Periapical disease in post-stroke patients.

PURPOSE: To assess the prevalence of acute periapical abscesses (PAs) in patients with history of stroke. METHODS: Integrated data of hospital patients was used. Data from the corresponding diagnosis codes for PAs and stroke were retrieved by searching the appropriate query in the database. The odds ratio (OR) of acute PAs and its association with post-stroke conditions was calculated and analyzed statistically. RESULTS: The prevalence of acute PAs in patients with stroke history was 1.39% as compared to 0.6% in the general patient population of the hospital. The OR was 2.78 and the difference was statistically significant (P< 0.0001). The prevalence of acute PAs in patients with a history of hemorrhagic stroke was 1.19% and the OR was 2.38. The difference was statistically significant (P< 0.0001). The prevalence of acute PAs in patients with a history of cerebral infarction was 1.55% and the OR was 3.11. The difference was statistically significant (P< 0.0001). The prevalence of acute PAs in patients with a history of cerebral infarction without hypertension was 0.87% and the OR was 1.75. The difference was statistically significant (P< 0.0001). CLINICAL SIGNIFICANCE: Oral healthcare providers should be aware of the possible higher prevalence of periapical abscesses in post-stroke patients. This can include patients with a history of hemorrhagic stroke or cerebral infarction.

The Effects of Dexamethasone on the Time to Pain Resolution in Dental Periapical Abscess.

BACKGROUND: Dental infections are frequently encountered in the emergency department (ED), with periapical abscesses being among the most painful. Traditional pain management strategies include local anesthetic injections, oral analgesics, and intravenous opioids. OBJECTIVES: We sought to identify an alternative pain management strategy with early use of dexamethasone as adjunct to conventional therapies for inflammation and pain at the site of infection. METHODS: We conducted a prospective, randomized, double-blind, placebo-controlled study comparing the analgesic effect of dexamethasone and placebo in ED patients with periapical abscess during a 2-year timeframe at two urban academic EDs. Adult patients presenting with physical examination findings consistent with a diagnosis of periapical abscess were randomized to receive oral dexamethasone or an identical placebo. Pain was assessed using the verbal numeric scale in person at discharge and via telephone at 12, 24, 48, and 72 h after discharge from the ED. RESULTS: Seventy-three patients were enrolled, with 37 receiving dexamethasone and 36 receiving placebo. Follow-up pain scores were obtained for 52 patients at 12, 24, 48, and 72 h. Ten patients from the dexamethasone group and 11 from placebo group were lost to follow-up. Patients who received dexamethasone reported a greater reduction in pain at 12 h compared with the placebo group (p = 0.029). Changes in pain scores from baseline and at 24, 48, and 72 h were not statistically significant. No adverse events were reported. CONCLUSIONS: Single-dose dexamethasone as adjunct to conventional medical management for pain caused by periapical abscess demonstrated a significant reduction in pain 12 h post treatment compared with placebo.

Mediastinitis as complication of odontogenic infection: A case report.

Odontogenic infections are one of the most common dental problems, which affect 80%-90% of the population. Untreated odontogenic infections can cause life-threatening complications such as necrotizing fasciitis, descending necrotizing mediastinitis, internal jugular vein thrombosis, cavernous sinus thrombosis, carotid artery pseudoaneurysm or rupture, and systemic inflammatory response syndrome. This report aims to present a mediastinitis case, in a 22-year-old healthy male patient, which originated from an odontogenic infection. The patient was hospitalized because of worsening general health status, despite the antibiotherapy. Computed tomography (CT) scan revealed that periapical abscess was spreading to the mediastinum through retropharyngeal space. The patient was successfully treated by IV antibiotherapy, transcervical drainage, and extraction of tooth.

Impact of odontogenic chronic rhinosinusitis on general health-related quality of life.

Chronic rhinosinusitis (CRS) may arise due to odontogenic etiologies. However, it is unknown whether odontogenic CRS has a differential impact on patients' quality of life (QOL) compared to standard, inflammatory (but non-odontogenic) CRS. The objective of this study was to determine whether there is a difference in the impact of sinonasal symptomatology on general health-related QOL in odontogenic CRS compared to non-odontogenic CRS. This was a retrospective review of 21 odontogenic CRS patients who visited our tertiary care center. The severity of sinonasal symptomatology and CRS-specific QOL detriment was measured using the 22-item Sinonasal Outcomes Test (SNOT-22) and general health-related QOL was measured using the health utility index from the 5-item EuroQol survey (EQ-5D HUV). Compared to non-odontogenic CRS, odontogenic CRS was not associated with a difference in SNOT-22 score [linear regression coefficient (ß) = - 1.57, 95% CI - 12.47 to 9.32, p = 0.777] but was significantly associated with decreased EQ-5D HUV (ß = - 0.10, 95% CI - 0.17 to - 0.03, p = 0.008). We also found that the magnitude of association (ß) between SNOT-22 and EQ5D-HUV was greater for odontogenic CRS patients compared to non-odontogenic CRS patients (p = 0.045). Our findings suggest sinonasal symptoms may have a greater impact on general QOL in odontogenic CRS compared to non-odontogenic CRS. The reason for this remains unknown, but deserves further study.

Cutaneous Sinus Tract from Mandibular Second Molar with C-shaped Canal System and Improper Former Root Canal Treatment: A Case Report.

Here, we report the diagnosis and treatment of an extraoral cutaneous sinus tract originating in a mandibular second molar with a C-shaped root canal system. The patient was referred to our department by a dermatologist after a series of unsuccessful treatments, including antibiotics. Diffuse radiolucency on a preoperative radiograph revealed that earlier root canal treatment had been only partially successful. Consequently, we performed retreatment of the root canal comprising removal of the former restoration and gutta-percha, cleaning and shaping, and passive irrigation with sodium hypochlorite. The patient responded well, and the cutaneous lesion completely resolved uneventfully within 1 month postoperatively. Preoperative recognition and thorough knowledge of the root canal anatomy and conventional methods of obturation are necessary in performing successful endodontic treatment.

Odontogenic cervical necrotizing fasciitis, etiological aspects.

INTRODUCTION: Cervical necrotizing fasciitis is a rare but very severe infection that affects the soft-tissues of the cephalic extremity. Cervical necrotizing fasciitis most frequently occurs secondarily to inflammatory odontogenic disorders and represents the most severe infection of maxillofacial spaces, with a high lethal potential. MATERIALS AND METHODS: In this study, we selected 55 patients with confirmed cervical necrotizing fasciitis of odontogenic origin, treated in the Clinic of Oral and Maxillofacial Surgery in Cluj-Napoca during January 1996-December 2012. RESULTS: In the majority of cases, the disease evolved without the presence of associated systemic disorders (60% [45.49-72.69]), the rest of the patients having 1-4 types of systemic disorders; type 2 diabetes mellitus was the most frequent type of underlying systemic disorder. From the appearance of the first symptoms until the presentation for treatment, a time interval of 2-30 days elapsed. During this time period, 78.18% (95% confidence interval [CI] [65.49-89.06]) of the patients received antibiotic treatment, but without results. Mandibular molars were the most frequent starting point of the disease, and the submandibular space was the first affected by the disease, 47.27% (95% CI [32.76-61.79]). Bacteriological exams showed that facultatively aerobic/anaerobic G + bacteria were the most frequently identified (72.22% [58.21-83.60]). CONCLUSION: The odontogenic lesions of the lower molars, complicated by submandibular space infections, are the most frequent starting point of odontogenic cervicofacial necrotizing fasciitis. Delayed surgical treatment and strict antibiotic therapy play an important role in favoring the development of odontogenic necrotizing fasciitis.

Increased levels of matrix metalloproteinase-3 in the sera and synovial fluids of patients with pustulotic arthro-osteitis associated with palmoplantar pustulosis: report of 2 cases.

Pustulotic arthro-osteitis (PAO) is occasionally seen in patients with palmoplantar pustulosis (PPP); however, its pathogenesis is still obscure. Herein, two patients with PAO associated with PPP were described. Both patients developed hydrarthrosis on the knees, along with sternocostoclavicular pain. Detail examination revealed odontogenic infection in both cases. Matrix metalloproteinase-3 (MMP-3) is a useful marker reflecting the activity of rheumatoid arthritis. In this study, MMP-3 levels in the sera as well as joint fluids were examined. Serum MMP-3 levels were increased in both cases (274 ng/ml in Case 1 and 242 ng/ml in Case 2, normal; 17.3-59.7). Also, MMP-3 concentration in the joint fluids was markedly elevated (Case 1 > 80,000 ng/ml and 48,000 ng/ml in Case 2). Our studies suggest that MMP-3 may play a role in the pathogenesis of joint involvement of PPP.

Orbital cellulitis as a complication of mandibular odontogenic infection.

A 30-year-old man presented with an acute left eye proptosis, pain, and decreased vision. He had been having a dental infection since 3 days. Orbital CT scan showed abscess in the left orbit. On dental X-ray a periapical radiolucency of the mandibular left-second molar was observed, and no obvious sinus involvement was noted. Intravenous antibiotic therapy did not lead to any significant improvement. Therefore, the patient underwent combined dental and orbital surgery to drain the abscess. Following the surgery, the patient's clinical signs and symptoms resolved completely.

Orodental diseases and dermatological disorders are highly associated in pet rabbits: a case-control study.

BACKGROUND: Dermatological disorders (DDs) and orodental diseases (ODDs) are a major source of morbidity in pet rabbits. Orodental diseases have anecdotally been associated with cutaneous disorders in rabbits. HYPOTHESIS/OBJECTIVES: The purpose of this study was to evaluate the possible association between DDs and ODDs and to determine whether ODD increases the risk of DD in pet rabbits. METHODS: This study was a retrospective review of 222 medical records of pet rabbits examined over 1 year in 20 private veterinary clinics. Records of rabbits diagnosed with DD were selected. Frequencies of ODDs and other variables were evaluated between rabbits with and without DDs using logistic regression. Rabbits seen during the same time period, but without a diagnosis of DD, were included as control animals. RESULTS: The prevalence of DD was 28.4% (63 of 222), and the prevalence of ODD was 23% (51 of 222). A significant association was present between DD and ODD. Rabbits diagnosed with ODD were 63 times (odds ratio 63.75; 95% confidence interval 23.9-170.2; P < 0.0001) more likely to be diagnosed with DD in comparison to rabbits without ODD. CONCLUSIONS AND CLINICAL IMPORTANCE: The results of this study indicate a strong association between ODD and DD. In particular, rabbits with ODD have a greater risk of developing skin disease later in life. Although coat condition and hair quality can be influenced by many biological and environmental factors, ODDs should be carefully considered as a possible underlying condition in rabbits showing DDs. More prospective studies are needed to evaluate whether this association is due to a behavioural disorder or a metabolic condition.

[Facial pain- a rare cause. Impacted lower third molars causing primarily "unclear" facial pain: a case report]. / Gesichtsschmerzen - eine seltene Ursache. Retinierte untere Weisheitszahne als Ursache fur zunachst <> Gesichtsschmerzen. Ein Fallbericht.

Orofacial pain often causes special difficulties to patients and dentists. Numerous differential diagnoses require the utilization of a coordinated diagnostic concept. Often, multiple causes lead to the need for a complex treatment plan. Impacted third molars are a potential cause of a variety of complications. Caries, pulp necrosis, and periapical infection are some of the infrequent causes of such pain. The presented case shows just such a constellation, resulting in primarily "unclear" orofacial pain. A diagnostic sequence generally leads to the correct diagnosis and thereby allows for fast and effective therapy. This shows how important structured diagnostics are, especially in cases of "unclear" pain.

Combined surgical and conservative endodontic management of Oehler's type 3b dens invaginatus aided by guided tissue regeneration.

The present case describes the successful healing of a periapical lesion associated with the left maxillary lateral incisor (# 22, Federation Dentaire Internationale) having a type 3b dens invaginatus tooth morphology. The treatment was complicated by the presence of blunderbuss root apex and large periapical lesion (>10 mm) with through and through bone defect (Bucco palatal cortical bone perforation, Von Arx Type 1b). An adolescent boy reported palatal swelling and pus discharge in relation to tooth #22. A thorough clinical and radiographic examination revealed tooth #22 as having a type 3b dens invaginatus with an open apex and a diagnosis of pulp necrosis and acute apical abscess. The case was managed by non-surgical root canal treatment followed by endodontic surgery using principles of guided tissue regeneration. A 5-year recall revealed an asymptomatic functional tooth with complete healing.

Increased Risk for Acute Periapical Abscesses in Multiple Sclerosis Patients and the Possible Association with Epstein-Barr Virus.

INTRODUCTION: Multiple sclerosis (MS) is a severe inflammatory neuroimmune degenerative condition affecting more than 2 million individuals worldwide. The purpose of this study was to assess the prevalence of acute periapical abscesses in patients with MS and to evaluate whether acute periapical abscesses (PAs) are more likely to affect patients who were previously infected by Epstein-Barr virus (EBV). METHODS: Integrated data of hospital patients were used. Data from the corresponding diagnosis codes for MS and acute PA were retrieved by querying the appropriate International Classification of Diseases, Tenth Revision codes in the database. RESULTS: Of the total hospital patient population, 0.18% were diagnosed with a history of MS. Females were more affected than males 3.25-fold. Whites were more affected than African Americans 6-fold. Whites were more affected than African Americans combined with other ethnicities 3.6-fold. The odds ratio (OR) for acute PAs in patients with a history of MS was 2.2 (P < .0001). After adjustment for diabetes mellitus comorbidity, the OR for acute PAs in patients with a history of MS was 2.6. After adjustment for cardiovascular disease comorbidity, the OR for acute PAs in patients with a history of MS was 1.27. Of the patients who presented with PAs, 0.2% were diagnosed with a history of EBV infection. The OR was 3.98, and the difference in prevalence was statistically significant (P < .0001). CONCLUSIONS: Under the conditions of this cross-sectional study, it appears that the prevalence of acute PAs is higher in patients with MS and that EBV may play a role.

An interesting healing outcome of a replanted immature permanent tooth: a case report.

A case of an avulsed upper left central incisor that was replanted after 3 h in a 7-year-old girl is presented. The tooth showed signs of an acute periapical abscess at 2 weeks after replantation. Apexification with mineral trioxide aggregate (MTA) following application of calcium hydroxide was attempted. At 3-year and 6-month follow-up, the tooth was asymptomatic with adequate clinical function. The radiograph showed resolution of the periapical lesion and apparent radiopaque tissue under MTA plug resembling root end morphology.

[Cerebral actinomycosis pseudotumor: a case report]. / Actinomycose cérébrale d'aspect pseudotumoral: à propos d'un cas.

INTRODUCTION: Cerebral actinomycosis is rare and difficult to diagnose. CASE REPORT: We report a case of a 45-year-old man hospitalized for seizures associated with fever and left hemiparesis. The white cell count and C-reactive protein were elevated. HIV serology was negative. Blood cultures remained sterile. The CT scan revealed hyperdense nodular lesions in the occipital area, with annular contrast uptake and peripheral edema causing a mass effect, suggestive of brain metastasis. The pathology examination of a surgical specimen disclosed cerebral actinomycosis. A dental origin of the infection was suspected. Hemiparesis remained after a 12-month antibiotic regimen associated with dental care and short-term corticosteroid therapy. CONCLUSION: Actinomycosis should be discussed as a possible diagnosis for all cerebral lesions, particularly in patients with a potential dental infection. Histology is required for positive diagnosis. Antibiotic therapy alone is generally sufficient; surgery is often performed for diagnostic purposes.

Florid cemento-osseous dysplasia and a dental abscess.

In most cases, FCOD is diagnosed by reviewing clinical and radiographic information and data. Multiple quadrants and a mixture of sclerotic radiopaque lesions with radiolucent borders facilitate radiographic interpretation. FCOD is a self-limiting condition that requires no further treatment once a diagnosis has been made. Prognosis is excellent. Follow-up is needed to assess for progression and any possible complications. This should include periodic radiographic evaluation. If endodontic therapy is required, it should not be initiated until a thorough clinical and radiographic evaluation has been completed.

Secrets to a successful awake fibreoptic intubation (AFOI) on a patient with odentogenous abscess.

Awake fibreoptic intubation (AFOI) is an established modality in patients with anticipated difficulty with tracheal intubation. This case demonstrates that with careful and meticulous preparations, AFOI can lead to improved airway management and excellent patient outcomes. A 38-year-old woman presented with severe trismus secondary to odentogenous abscess was identified preoperatively as having a potential difficult airway. AFOI was performed successfully using combined Spray-As-You-Go and dexmedetomidine technique.

Rapid treatment reduces hospitalization for pediatric patients with odontogenic-based cellulitis.

PURPOSE: The study aimed to assess characteristics of facial cellulitis admissions and their relationship to cost of hospitalization (COH) and length of stay (LOS) in children ages 0 to 20 years at an urban hospital and to compare outcomes of rapid management to published and national statistics for LOS and COH. METHODS: A retrospective review of 376 charts of facial cellulitis admissions between 2000 and 2006 revealed 63 of confirmed odontogenic cases from which cellulitis characteristics, COH, and LOS were gleaned. Variables were correlated to LOS and COH. Data on LOS and cost of admission were compared to published studies and 506 entries from the 2006 Kids' Inpatient Database (KID). RESULTS: Of 63 charts included, children included were 8.3 years (SD, +/-3.8 years) and equal in sex distribution. Treatment rendered and site of infection had no significant relationship to COH. Overall mean hospital LOS was 2.08 days and significantly less as compared to 3.97 days for published studies and 3.4 days for KID (P < .0001). The mean overall hospital COH was $4166 and significantly less compared to $3223 in the literature and $8998.43 for KID. CONCLUSION: In the management of pediatric facial cellulitis of odontogenic origin, rapid treatment had a significant positive impact on length of stay and total cost of treatment compared to published studies and nationally reflective data.

Odontogenic sinus tract to the chin: a diagnostic dilemma.

Sinus tracts of odontogenic origin most commonly open into the oral cavity but occasionally may drain extraorally. The diagnosis is more difficult when necrosis of the tooth occurs in the absence of dental caries. We report a 23-year-old man with a long-standing chronic wound on the inferior aspect of the chin that was refractory to treatment. This case demonstrates the use of a simple technique to identify a necrotic mandibular incisor tooth as the source of infection.

Continued root formation after replantation and root canal treatment in an avulsed immature permanent tooth: a case report.

This case report describes the continued root formation following replantation and conventional root canal therapy of a traumatically avulsed open-apex tooth with suppurative apical periodontitis. A 7-year-old male patient had an avulsed upper left central incisor (tooth 21) replanted approximately 50 min after traumatic avulsion. A root canal procedure was initiated due to pulp necrosis and periapical abscess detected in the follow-up period. After endodontic treatment with calcium hydroxide (Ca(OH)(2)) dressing, a normal root length developed including an apical segment beyond the hard tissue barrier. Regeneration of the root occurred without pathology or ankylosis at 1-year of follow up.
