Dental treatment for children with chronic idiopathic thrombocytopaenic purpura: a report of two cases.

Idiopathic thrombocytopaenic purpura (ITP) is the most common acquired bleeding disorder occurring in previously healthy children. The condition is benign and self-limiting, with a high possibility of recovery. Only 15-30% of children with acute ITP develop the chronic form. Clinically, ITP presents with petechiae, ecchymoses, haematomas, epistaxis, haematuria, mucocutaneous bleeding, and occasionally, haemorrhage into tissues. Oral manifestations include spontaneous gingival bleeding, petechiae or haematomas of the mucosa, tongue or palate. Two paediatric case reports are described concerning female patients diagnosed with chronic ITP. Oral findings and dental procedures are described. Standard dental treatment was performed with a platelet count higher than 50,000/mm3. The importance of adequate dental plaque control techniques in order to prevent inflammation, potential bleeding and infection in these patients is emphasized. The paediatric dentist must be aware of the clinical appearance of ITP in order to recognize the condition and successfully manage the patient.

Microbiological evaluation of periapical infections in Egypt.

This study identifies and correlates proportions of bacteria in periapically involved anterior teeth of 85 adult Egyptian patients. Affected sites were free from caries and periodontal disease but had a history of trauma. The mean number of component bacterial species per specimen was 3.1. Anaerobic bacteria were the dominant flora present in specimen cultures, comprising 73% (190/259) of cultivable bacteria. The most frequently isolated organisms were Eubacterium species (68%), black-pigmented Bacteroides (56%), Streptococcus morbillorum (47%) and non-pigmented Bacteroides (37%). These organisms also showed the highest proportional values relative to total cultivable bacteria. The mean percentages of total viable counts of these isolates were 19.0%, 14.1%, 18.0% and 15.5%, respectively. Statistical analysis of data revealed a significant negative correlation between S. morbillorum and Bacteroides species.

Periapical curettage: an alternative surgical approach to infected mandibular cheek teeth in horses.

OBJECTIVE: To evaluate an alternative surgical method for treating periapical infection of the mandibular cheek teeth of horses. DESIGN: Retrospective study. ANIMALS: Eleven horses (3-13 years) with periapical mandibular tooth infection. METHODS: Hospital records (1992-2002) of horses that had periapical curettage for the treatment of mandibular cheek tooth root infection were retrieved. Clinical signs, radiographic, and surgical reports were reviewed. Outcome was obtained by telephone questionnaire for 7 horses and by physical examination in 2. RESULTS: Eleven horses (14 infected mandibular molariform teeth) had periapical curettage. Two horses were lost to follow-up. Mean follow-up was 41 months; 2 horses had subsequent tooth repulsion, 7 (78%) horses healed completely although 2 horses still had some local mandibular swelling. CONCLUSION: Periapical curettage, which allows alveolar drainage, appears to be a viable treatment option for periapical infections of equine mandibular cheek teeth. CLINICAL RELEVANCE: Periapical curettage can be performed simply, without expensive imaging or surgical equipment, and thus is useful for both referral and first opinion practice.

Dental health of young Vietnamese immigrants.

About 3000 refugees from Vietnam have come to Norway in the last 5 years. A survey, including a clinical and radiographic examination for caries and gingival health, was carried out on 142 refugees. They were aged from 2 to 18 years and were examined within 6 weeks of arrival in Norway. The mean dmfs score of subjects 2-5 years old was 23.9, for subjects 6-11, dmfs was 12.4 and DMFS 7.7, and for subjects 12-18, DMFS was 20.0. The dmf/DMF scores were mainly composed of caries grades 3 and 4 (dentin caries or caries with pulpal involvement), and teeth missing or indicated for extraction. Only eight subjects had restorations, and these were often of poor quality. All subjects over 6 years had gingivitis (GBI 62%). About 10% had enamel hypoplasias on permanent anterior teeth. Dental abscesses and periapical areas indicated an acute treatment need, and most subjects were in urgent need of restorative treatment. Average time required for treatment of 12-18-year-old patients is estimated to be 7-10 hours, about four times that required for Norwegian schoolchildren. Dental examination of newly arrived Vietnamese refugees is recommended.

Experimental periodontal breakdown in the dog.

This paper describes a method for inducing rapidly progressing and reproducible periodontal lesions around selected teeth in dogs. The experiments were performed on 10 beagles which were fed a diet favoring gross formation of plaque. Approximately 1 mm of the marginal alveolar bone aroumd 4P and P4 was removed and a notch prepared in the root. A ligature of cotton floss was placed around 4P and P4 at the cemento-enamel junction. Radiographs and sections prepared 230 d later revealed that a progressive breakdown of the periodontal tissues had occurred. The average bone loss was 2.4 mm and the distance between the apical cells of the pocket epithelium and the notch was 854 mum.

Ultrastructure of a novel anaerobic gram-positive nonsporing rod from dental root canal.

A novel anaerobic Gram-positive rod, strain ES4C, was isolated from a dental root canal infection. The isolate did not produce acids from carbohydrates and showed no glycosidase activity. Most biochemical reactions were identical to Clostridium malenominatum with the exception of the production of three aminopeptidases. In addition, no spores were detected. A tetragonally arranged surface layer was consistently found by electron microscopy. The ultrastructure of closely related Eubacterium spp. was also studied, but no crystalline surface structures were found. The physiologic and ultrastructural characteristics of ES4C did not allow identification as any known species. The periapical lesion responded to routine root canal therapy, but after 18 months observation the radiologic signs indicated partial healing only.

Endodontic management of mandibular lateral incisor fused with supernumerary tooth.

In this article we report a case of a mandibular lateral incisor in which 3 separate root canals were located. Clinical and radiographic examinations suggested that fusion had occurred between the mandibular incisor and a supernumerary tooth. The endodontic management of the tooth is described, and repair of an apical periodontitis had occurred after 9 months.

Treatment of large periapical lesions by inserting a drainage tube into the root canal.

Long-term drainage and depressurization is performed by inserting a stainless steel tube into the root canal of teeth with persisting periapical exudation. This article presents 2 cases of large periapical lesions showing a complete healing of bone after the drainage tube procedure. The tube allows lasting drainage, relieves the pressure and modifies the local apical environment so the host defense mechanism can exert repair process.

Treatment of middle-apical level root fracture in necrotic teeth.

The purpose of this paper is to present two case reports of dental trauma with middle-apical level root fractures and pulp necrosis. The treatment consisted of programmed applications of calcium hydroxide until a calcified barrier was formed at the fracture level. The technique presented here proved efficient in treating horizontal fractures at the middle and apical thirds of the root.

Idiopathic myelofibrosis: dental treatment considerations.

Idiopathic myelofibrosis is a myeloproliferative disorder of unknown origin. The bone marrow becomes fibrotic with an associated decrease in hematopoiesis resulting in anemia, bleeding problems, splenomegaly, and other secondary abnormalities. Although idiopathic myelofibrosis is usually diagnosed in middle age, there have been a few reports of the disorder in the pediatric population. This case report documents dental treatment considerations in a 6-year-old female with idiopathic myelofibrosis, severe anemia, and abnormal blood coagulation studies. The patient was successfully treated in a hospital after medical consultation, transfusion of packed red blood cells, and administration of prophylactic antibiotics. Local hemostatic measures following multiple extractions of carious teeth controlled bleeding. No postoperative sequelae occurred.
