A radiological investigation into the age changes of the inferior dental artery.

An angiographic study of 23 cadavers and 100 patients showed that arterial disease affected the inferior dental artery earlier in life than the rest of the carotid arteries and their branches. Approximately a 15-year difference was noted, the difference being highly significant statistically. The loss of teeth was associated with these changes but statistically the correlation was less significant. The possible reasons for these changes and the surgical implications are discussed.

The influence of the loss of teeth and attrition on the articular eminence.

A review of the literature revealed that changes in the articular eminence associated with changes in the dentition were usually overlooked in most reports. An attempt was made to determine whether changes in attrition and loss of teeth would correlate with a change (decreased angulation) in the articular eminence. The population consisted of 103 adult skulls and mandibles of both sexes and three different races. They included partial and totol edentulism, mild to severe attrition, and complete dentitions in good condition. An impression of each of the 206 articular eminences was made and the angulation established. The data were transferred to computer cards and a statistical analysis performed. The level of significance for each of the variables was established and conclusions were made.

Reconstruction of the alveolar process by implantation of allogenic demineralized dentin.

Different materials have been used for reconstruction of the alveolar process. None of these, however, is perfect in every respect. Allogenic demineralized dentin has been shown to induce bone formation and to maintain the bone contour. In the present case this material was used to reconstruct a traumatic defect of the alveolar process in the region of the upper left incisors. The result was satisfactory, both esthetically and functionally. Additional cases and a longer period of observation will be necessary to assess the relevance of this finding.

Alveolar bone necrosis and tooth loss. a rare complication associated with herpes zoster infection of the fifth cranial nerve.

Eleven case reports involving herpes zoster infection associated with alveolar bone necrosis and tooth loss were reviewed in order to develop a patient profile for this rare combination of physical findings. The clinical course of a 56-year-old white woman with herpes zoster infection of the fifth cranial nerve and related alveolar bone necrosis, tooth loss, and oroantral fistula development is reported. The etiology and management of herpes zoster infection associated with destructive oral sequelae are discussed.

Tricho-dento-osseous syndrome. Features of the hair and teeth.

Tricho-dento-osseous syndrome is a rare autosomal dominant hereditary disorder characterized by curly hair, enamel hypoplasia, taurodont teeth, and thickened cortical bone. A large kindred with this syndrome has been identified in North Carolina and characterized by pedigree analysis and clinical evaluation. Hair samples (N = 3) and an exfoliated primary tooth (N = 1) from persons with tricho-dento-osseous syndrome and hair and teeth from unaffected persons were examined. Scanning electron microscopy showed that the hair shaft morphology, diameter, and cuticular pattern and periodicity were similar for the tricho-dento-osseous syndrome and control samples. The affected tooth was examined using light microscopy and a scanning electron microscope that showed pitting hypoplasia of the enamel surface, an extremely large pulp chamber, and dentin that appeared structurally normal. The affected enamel was uniformly thin, only 10% the thickness of the control enamel. The bulk of this enamel showed no prism formation. This study indicates that although hair with tricho-dento-osseous syndrome often is clinically curly, it can be straight, and it does not appear to have unique ultrastructural features that are of diagnostic benefit. The dental characteristics of tricho-dento-osseous syndrome were the most consistent feature seen in this kindred.

Periodontics in general practice: perspectives on periodontal diagnosis.

Standardized terminology does not exist to differentiate the conditions that constitute "response diagnosis" and "disease diagnosis" described in this review. Therefore, appropriate descriptive terminology is proposed for these two periodontic diagnoses. Diagnostic terms are needed to discern stages of disease. Periodontitis is a chronic disease prone to episodic recurrence that needs a "dynamic diagnosis" that can change with each reevaluation. In addition, the legal ramifications of failing to recognize or adequately described disease recurrence are discussed.

Oral and maxillofacial manifestations of hereditary sensory neuropathy.

Hereditary sensory neuropathies are a rare group of neurological disorders manifested from early childhood by diminished or absent sensibility to pain, touch and temperature. A Kashmiri family with four members affected by congenital sensory neuropathy and its oral manifestations is described. Pain and temperature sensation was lost in various parts of the body including the orofacial region resulting in mutilating acropathy, particularly of the limbs and face. Orofacial motor function was normal. Three of the four members had corneal opacification due to scarring from keratitis. To prevent any further mutilation, any corrective surgery is best delayed until the patient is old enough. A discussion of the oral manifestations of this condition with a review of the literature is presented.

Tooth eruption in a patient with craniometaphyseal dysplasia: case report.

Craniometaphyseal dysplasia (CMD) is a very rare genetic disorder of bone remodeling caused by osteoclast dysfunction. The clinical and radiographical features of oral findings are presented in a sporadic case of CMD in a child (age 10 years, 7 months). An intraoral examination showed severe malocclusions, including anterior crossbite and deep bite. Furthermore, a radiographic examination showed increased radiopacity of the maxilla and mandibular bones due to hyperostosis and sclerosis of the jaw. There was no root resorption of the canines or molars in the primary dentition, although root formation of the permanent teeth was proceeding. Dental age was calculated to be approximately 1 year, 4 months younger than his chronological age. The eruption speed of the permanent lateral incisors after the gingival emergence was shown to be within normal values, and we discuss whether the canines and premolars in the permanent dentition could erupt or not.

Characterization of a family with dominant hypophosphatasia.

A kindred with dominant hypophosphatasia resulting from an alanine to threonine substitution at position 99 of the alkaline phosphatase protein is described. The clinical findings of individual members of the kindred were assessed by oral and physical examinations, or from the descriptions of multiple family members. The proband displayed enamel hypoplasia and premature loss of fully rooted primary anterior teeth, which were shown by histological examination to lack cementum. Serum alkaline phosphatase (ALP) and a vitamin B6 panel, and urine phosphoethanolamine (PEA) were measured on 21 family members. Based upon the clinical and laboratory tests, affected and unaffected status was assigned. Parametric linkage analysis of the kindred using different dominant models and frequency distributions for the disease allele and the mutation gave lodscores > 4.2 and confirmed the strong linkage between the disease and the mutation. Assuming the defined mutation causes the disease, the reliability of clinical and laboratory tests is assessed.
