Trigeminal herpes zoster causing mandibular osteonecrosis and spontaneous tooth exfoliation.

We have described a 60-year-old woman with polymyalgia rheumatica treated initially with prednisone but ultimately with azathioprine and cyclophosphamide. Herpes zoster infection along the mandibular division of the right trigeminal nerve ensued with spontaneous exfoliation of two teeth. She subsequently died. Medical practitioners need to be made aware of this rare complication of a common disease.

Alveolar bone necrosis and tooth exfoliation following herpes zoster infection: a review of the literature and case report.

BACKGROUND: Herpes zoster (HZ) presents as a cutaneous vesicular eruption in the area innervated by the affected sensory nerve, usually associated with severe pain. Oral manifestations of HZ appear when the mandibular or maxillary divisions of the trigeminal nerve are affected. METHODS: This is a case report of a 63-year-old woman with HZ infection with trigeminal nerve involvement that led to a rapid loss of alveolar bone and exfoliation of two teeth. RESULTS: The initial intraoral examination showed redness of the alveolar mucosa and gingiva of the lower right quadrant with multiple well-delimited and painful erosive lesions affecting the attached gingiva around the teeth. Two weeks later, teeth number 27 (lower right canine) and 28 (lower right first premolar) had class III mobility, flow of purulent exudate from the gingival sulcus, and deep pockets (>11 mm). The radiological examination showed advanced alveolar bone loss around both teeth. The prognosis for teeth number 27 and 28 was considered hopeless, and they were extracted. Due to extensive necrosis there was no interdental alveolar bone. The case is presented with a review of clinical data from patients with trigeminal HZ infection associated with osteonecrosis or exfoliation of teeth previously reported in the literature. The mechanisms by which the HZ infection leads to the alveolar bone necrosis are discussed. CONCLUSIONS: Extensive osteonecrosis and exfoliation of teeth in the area innervated by the nerve affected by HZ has been reported after HZ infection. Clinicians should be aware of this possible outcome after a trigeminal HZ infection.

[A longitudinal study of tooth exfoliation and dental caries in adults in Gucheng village].

In order to observe the Age-Related changes in dental health conditions, we selected Gucheng village, a rural area of Beijing as a surveillance place for our longitudinal study. 575 persons in different age groups were examined in 1984 and 507 persons were reexamined in 1989. The rate of reexamination was 86.4%. During the 5-year period, 0.3-1.8 teeth were missing in 20-40 years old groups and 2.8-5.5 teeth were missing in 50-70 years old groups. Beyond 60 years old groups more than 43% original remaining teeth were missing or present as residual roots. More than 10% original healthy teeth were decayed and more than 90% original caries teeth became aggravated in elderly group within 5 years. This study indicates that the incidences of tooth mortality and dental caries are much higher in elders than in young adults.

Iatrogenic exfoliation of a tooth following abuse of a rubber dam: a case report.

This report presents a case in which tooth exfoliation followed rubber dam abuse. A 40-year-old patient was referred to the prosthodontic clinic with complaints of mobility and discomfort in tooth 44, which had received an amalgam restoration. While this tooth was scaled, a piece of rubber dam appeared in the buccal sulcus. Removal of the rubber piece was followed by thorough scaling and tooth splinting. Tooth deterioration continued, and concern for the adjacent teeth necessitated extraction of tooth 44. To avoid such undesirable consequences, the integrity of the dam should be verified on its removal.

The survival of resin modified glass ionomer and stainless steel crown restorations in primary molars, placed in a specialist paediatric dental practice.

AIMS: To prospectively report on the survival of resin-modified glass ionomer cement (RMGIC), photac-fil and pre-formed stainless steel crown (SSC) restorations in primary molar teeth placed over a seven-year period in a specialist paediatric dental practice under private contract of remuneration. METHOD: All primary molar restorations placed by a specialist paediatric dentist over a seven-year period were reviewed and the outcome results recorded. Data were recorded at review visits until June 30, 2003. Data recorded included Class I restorations, Class II restorations and SSC. The Class II cavities were either mesial or distal, with or without buccal/palatal extensions. If both proximal surfaces were decayed or if after cavity preparation the resultant outline form was significantly larger than the minimal classical form, RMGIC was not used; an SSC was placed instead. Stainless steel crown preparation followed conventional guidelines. The crowns were cemented with reinforced zinc oxide and eugenol (Kalzinol). The status was recorded as satisfactory restoration, tooth exfoliated, tooth extracted for orthodontic reasons with the date of extraction, or needing replacement. If replaced then the reason for replacement was also recorded. RESULTS: A total of 544 Class I RMGICs, 962 Class II RMGICs, and 1,010 SSCs were placed. At the last review of each restoration, 98.3% of Class I, 97.3% of Class II RMGICs and 97.0% of SSCs were either satisfactory or withdrawn intact. CONCLUSION: Under the conditions of private specialist practice-based study SSCs continued to prove very successful for the restoration of larger cavities and for pulp-treated primary molar teeth. For the smaller cavities RMGIC were also very successful.

Large arteriovenous high-flow mandibular, malformation with exsanguinating dental socket haemorrhage: a case report.

Arteriovenous malformations (AVMs) of the jaws are extremely rare lesions, which are probably hamartomas of developmental malformations. In this article we present an extremely high-flow AVM of the lower jaw with exsanguinating bleeding from the socket of the exfoliated tooth. Repeated episodic bleedings were controlled with local pressure and packing. Digital subtraction angiography revealed a high-flow, high-shunt AVM. Preoperative embolization and external carotid artery ligation, dental extraction, curettage and packing with Gelfoam were done. Postoperative bleeding stopped, bruit ceased, and it had disappeared completely after 6 months follow-up. On the second follow-up visit, 3 months later, the patient was found to have no problems.

Eruption of tooth-like structure following the exfoliation of natal tooth: report of case.

Natal teeth, defined as those that are the mouth at birth, are rare: one case in 2,000 to 3,500 births. In this case, that of a nine-month-old Japanese boy, it is reasonable to infer that the tooth-like structure, described as a hard-tissue conglomerate with a bone-like appearance, originated in the remnant of the dental papilla and Hertwig's sheath of the natal tooth. Both dentin and root formation were thereby induced.

A bizarre facial sinus.

A 63-year-old Caucasian man presented to his general dental practitioner with a spontaneously exfoliated lower central incisor and hair growing from the socket. Examination revealed a hair-filled sinus from the skin of the median aspect of his chin to the socket of the exfoliated tooth. This was confirmed histopathologically following excision biopsy.
