Spontaneous regeneration of the parotid salivary gland following juvenile recurrent parotitis.

Sialograms of an 18-year-old female patient known to suffer from juvenile recurrent parotitis (JRP) disclosed the destructive glandular changes typical of the disease. During the 10 years subsequent to the sialographic examination, the patient did not experience any further attacks of JRP. Sialograms carried out when the patient was 28 years of age demonstrated a normal gland. This case illustrates that a damaged parotid gland is capable of regeneration following JRP.

Changes in the parotid salivary gland of beta-thalassemia patients due to hemosiderin deposits.

2 patients afflicted with beta-thalassemia major presented with pain and swelling of the parotid salivary gland. In 1 patient, the symptoms were of long standing and particularly severe, with diminished and highly viscous salivation. In the other patient, the parotid glands had only recently become painful, while salivary output and quality remained normal. The parotid anatomy in both patients, as demonstrated by sialography, and the clearance of opaque material were normal. Tc99 scintigraphy revealed reduced uptake and rapid clearance of the isotope from the parotid serous glands into the oral cavity, in contrast to the increased uptake by the sublingual mucous glands. Iron deposits were demonstrated in the parotid secretory serous cells. It is postulated that the impaired function of the parotid is linked to iron deposits in the serous cells of this gland, as a sequella of beta-thalassemia.

Intraligamentary--intraosseous anesthesia. A radiographic demonstration.

Intraligamentary dental anesthesia has become a widely accepted technique. The periodontal ligament seems to provide easy access to the tooth apex. In the present study, radiopaque material was injected into baboon monkeys. Serial radiographs during incremental injections showed clouding of the crestal bone. The material was seen gradually advancing through the alveolar bone crest, apically. The spread was noticed through the marrow spaces, unexpectedly avoiding the PDL route.

Does an impacted tooth cause root resorption of the adjacent one?

External root resorption caused by an adjacent impacted tooth was studied radiographically in 199 cases. Resorption of the root had occurred in fifteen instances (7.5 per cent), the cervical region being least affected. The incidence was highest in the 21 to 30-year-old group and mainly involved male patients. Resorption of the periodontium alone was found in sixteen additional patients; of these, five were followed for 1 year after extraction of the impacted tooth. During this period, the damaged periodontium was completely re-established.

Scleroderma: oral manifestations.

An oral clinical and radiologic study of twenty-one patients suffering from scleroderma revealed that in one half of the patients the blood sedimentation rate and the antinuclear factor were elevated. When both these laboratory findings were present at the same time, they proved to be well correlated. The majority of the patients had limited mouth opening. Gross jawbone changes affecting the mandibular condyle, coronoid process, and posterior part of the ascending ramus occurred in four patients. There was no correlation in these four patients with regard to the bone changes and clinical and laboratory findings or to age and duration of illness. Widening of the periodontal ligament space, as measured in a meticulous manner, was a feature in all twenty-one patients and in all teeth.

Mandibular tumor-induced muscular weakness and osteomalacia.

The case presented is that of a 26-year-old man who suffered from muscular weakness and aching pains 2 years prior to hospitalization. During that period, a tumor in the mandible was diagnosed. During the neurologic work-up to find the cause of the muscular weakness, the possibility of a metabolic bone disease was raised on the basis of oral findings. The giant-cell nature of the mandibular tumor, with destruction of the periodontium, suggested hyperparathyroidism. The giant-cell nature of the mandibular tumor, with destruction of the periodontium, suggested hyperparathyroidism. However, biochemical findings ruled out this diagnosis and led to the final diagnosis of "tumor-induced osteomalacia." Removal of the mandibular tumor caused substantial improvement in the patient's physical condition and in the biochemical picture, which confirmed the diagnosis.

Burkitt's lymphoma cell leukemia. Radiology and cytotoxic medication.

A 15-year-old girl presented with swelling and spontaneous bleeding of the gingiva. The lower anterior teeth were sensitive to percussion, and the lower lip and chin showed lack of sensation. Radiographically, gross loss of the alveolar and basal bone in both jaws was evident. The lamina dura and periodontal ligament had lost their morphology. Based on the clinical, radiographic and laboratory findings, the diagnosis of Burkitt's lymphoma cell leukemia was made. While cytotoxic medication brought about an immediate clinical improvement, radiographically, jaw bone repair became evident one month following initiation of treatment.

Experimental transplantation of mature molar teeth with and without the supporting structures in mice.

Two types of dental isografts were implanted into the femoral bone of inbred mice: type A, encompassing mature maxillary molars including supporting structure and type B, consisting of the tooth alone. The isografts, together with their host tissues, were examined histologically beginning at day 1 and continuing until day 42 posttransplantation. In both types, the cellular components underwent necrosis with subsequent repopulation of the pulp and periodontal ligament of the graft. A new bony socket formed and partial resorption and ankylosis started on day 10 of transplantation. It is suggested that the host cells present in the periodontal ligament are responsible for the ankylosis and resorption of the tooth root surface.

Odontoma in the subcondylar region.

An instance of a compound odontoma in the condylar process in a 24-year-old female is described. Location of odontomas in the coronoid or condylar processes were not reported. A hypothesis of migration of the third molar bud into the condylar region, an interfering local factor such as trauma or infection are suggested as aetiologic factors to the tumour in this case. Pre-operative radiographic localisation of the mass, are essential for treatment planning. An intra-oral approach was the treatment of choice.

The diagnostic value of computed tomography in temporomandibular joint synovial chondromatosis.

Synovial chondromatosis of the temporomandibular joint was diagnosed and location of dens particles was assessed by means of computed tomography. Based upon the data collected, the joint was operated conservatively and most of the calcifications were removed leaving the patient symptom free. The importance of an accurate preoperative diagnosis of synovial chondromatosis by use of CT scan is stressed in view of numerous unnecessary condylectomies and parotidectomies reported in the literature.
