[Studies of oral microbiogenesis. II. Significance of staphylocci present in periodontal lesions, pulp gangrene and in the alveolus after tooth extraction].

A study was carried out on the properties and significance of staphylococci isolated from the alveoli after dental extraction (12 strains), from parodontal pus (19 strains) and pulpar gangrene (15 strains). By their frequency, staphylococci of the Staphylococcus aureus have an etiologic significance in pulpar gangrene. Of particular importance for the diagnosis and epidemiology was the predominance of lysotype 80 among the staphylococci isolated from pulpar gangrene and lysotype 77 in healthy carriers. In 2 of 11 patients the coexistence of the same lysotype was found in the pulpar gangrene and nasal secretion.

Osteoradionecrosis of the jaws as a side effect of radiotherapy of head and neck tumour patients--a report of a thirty year retrospective review.

This retrospective study aimed to demonstrate the incidence and the aetiological factors involved in osteoradionecrosis (ORN) in a group of 830 head and neck tumour patients who received radiotherapy between 1969 and 1999. The data showed an over all incidence of 8.2% and a 3-fold higher incidence for men than for women. Osteoradionecrosis was most commonly located in the body of the mandible. Concerning the risk factors, a negative influence was shown for advanced tumours, segmental resections of the mandible and pre-/post-radiation tooth extractions. Tooth extractions were found to be responsible for 50% of all cases. The osteoradionecroses were observed significantly earlier in patients who received pre-surgical radiotherapy than those who received post-surgical radiotherapy. Combined pre-surgical radio- and chemotherapy significantly hastened the appearance of osteoradionecrosis compared to pre-surgical radiotherapy alone. Only 40% of patients with osteoradionecrosis could be healed completely by means of surgery and antibiotic medication. Hyperbaric oxygenation (HBO) therapy was performed only in individual cases. The data suggest that osteoradionecrosis has a multifactorial aetiology. Therefore, a very close follow-up of tumour patients and a strict prophylactic management are required.

Treatment of root perforation by intentional reimplantation: a case report.

Intentional reimplantation is defined as a procedure in which an intentional tooth extraction is performed followed by reinsertion of the extracted tooth into its own alveolus. In this paper, intentional reimplantation is described and discussed as a treatment approach to root canal instrument separation in conjunction with root perforation. An 8-year follow-up case report is presented. The reimplanted tooth is now a fixed bridge abutment. Although successful in this case, the intentional reimplantation procedure should be considered a treatment of last resort, that is, when another treatment option is not viable for the treatment of root perforation/instrument retrieval.

HIV status and the risk of post-extraction complications.

Tooth extraction is commonly performed for patients infected with the human immunodeficiency virus (HIV). We undertook a prospective study to determine if HIV-positive patients had an increased risk for complications following tooth extraction. The study sample was composed of patients who presented for tooth extraction to the outpatient oral/maxillofacial surgery clinic at Grady Memorial Hospital, Atlanta, GA. The predictor variable was HIV status (positive or negative). The outcome variable was the presence or absence of a post-extraction complication. Other study variables were grouped into the following sets: (1) demographic, (2) past medical and social history, (3) clinical, (4) laboratory values, and (5) treatment. Between 11/93 and 4/96, 166 patients were enrolled. The study sample was composed of the 151 patients who completed the study protocol and consisted of 76 HIV-positive and 75 HIV-negative patients. The post-extraction complication rates were 22.3 and 13.3% for the HIV-positive and -negative groups, respectively (relative risk = 1.68, 95% confidence interval = 0.82 to 3.42, p = 0.15). The types of complications that occurred were similar in both groups. While the data suggest an increased rate of post-extraction complications in the HIV-positive group, the difference in complication rates between the two groups was not statistically significant. In addition, the complications were minor, self-limiting, and readily treated. Based on these findings, we believe that tooth extraction is a low-risk procedure in HIV-positive patients. Treatment may be rendered routinely to patients who present on an outpatient basis without the need for an extensive pre-operative work-up, unless otherwise indicated by relevant history.

A clinical evaluation of dry socket in a Nigerian teaching hospital.

PURPOSE: We sought to determine the incidence of dry socket in a Nigerian teaching hospital and to evaluate the patients' demographic pattern, predisposing factors, the treatment given, and treatment outcome. PATIENTS AND METHODS: A retrospective review of records of dental extractions complicated by dry socket in Obafemi Awolowo University Teaching Hospital, Ile-Ife, between January 1996 and December 2000 was undertaken. Information retrieved included patient sociodemographic data, indications for extraction, tooth extracted, status of attending surgeon, onset of symptoms, relevant findings of the examining clinician, interval before presentation, treatment given, and its outcome. RESULTS: Of the 3,319 dental extractions performed in 3,008 patients, 136 (4.1%) were complicated by dry socket. The patients' mean age was 33.4 (15.4) years and a peak age incidence of 21 to 30 years was found. A slight female preponderance (1.4:1) was observed. The majority of patients were in the low-income group, and presentation in the hospital was prompt in the high-income group. Mandibular teeth were affected 3 times more than maxillary teeth (P =.00080). Most cases of dry socket resulted from extractions performed by undergraduates and house officers. Various underlying systemic conditions were found in 11.0% of cases, none of which included use of oral contraceptives. Treatment was usually the use of zinc oxide eugenol dressing in an irrigated socket, combined with antibiotic therapy in 45.3% of cases. No adverse reaction to zinc oxide eugenol was observed. CONCLUSION: The incidence of dry socket in our hospital is 4.1%. The mandible was involved 3 times more than the maxilla. With the use of zinc oxide eugenol dressing, 70.6% of patients completed treatment satisfactorily and 29.2% were lost to follow-up.

An iatrogenic foreign body (dental bur) in the maxillary antrum: a report of two cases.

Two cases of foreign bodies of the antrum are reported. One was a turbine bur which presumably entered through an oro-antral fistula after a tooth extraction. The other was also a turbine bur where the mode of entry was not clear (lack of oro-antral fistula), but it presumably entered through the socket of the extracted tooth. The mucosa of the antrum appeared normal in spite of the lengthy presence of the foreign body.

Burkitt's lymphoma of the ovary in pregnancy.

BACKGROUND: Burkitt's lymphoma is a rapidly growing and, if untreated, rapidly fatal tumor derived from B-lymphocytes. The occurrence of Burkitt's lymphoma during pregnancy is rare. CASE: A patient with Burkitt's lymphoma presented at 12 weeks of gestation with abdominal and tooth pain. An 11 x 11 x 15 cm mass was seen on abdominal/pelvic ultrasonogram. She underwent a left salpingo-oophorectomy with removal of the mass, as well as a tooth extraction. The pathology examination confirmed lymphoma in the left ovary and in the tissue surrounding the extracted tooth. After surgical resection, she was treated with multiagent chemotherapy beginning at 13 4/7 weeks of gestation. At 39 weeks, she delivered a viable female infant weighing 2,270 g. CONCLUSION: The finding of an adnexal mass in conjunction with head and neck symptoms led to consideration of Burkitt's lymphoma. Prompt treatment with multiagent chemotherapy should be considered for pregnant patients with Burkitt's lymphoma.

Orbital abscess: visual loss following extraction of a tooth--case report.

OBJECTIVE: It is the purpose of this article to alert the general practitioner to the severe consequences that may result from a tooth extraction, including the loss of vision, despite the use of antibiotics. CONCLUSIONS: Early and aggressive treatment is critical in obstructing the spread of infection toward the orbits, the eyes, and eventually the brain.
