Widespread radiopacity of jaw bones in familial adenomatosis coli

Abnormalities of jaw bones and teeth were evaluated in 37 patients with familial adenomatosis coli (FAC) by means of orthopantomography. Osteomatous radiopaque lesions were evident in 75.7 percent of FAC patients (focal type: 62.2% and wide spread type: 13.5%), odontomes in 29.7% peripheral osteomas in 13.5%, unerupted teeth in 16.2% and supernumerary unerupted teeth in 16.2%. Five of the 37 FAC patients had an unusual widespread type of radiopacity with other abnormalities. Combined abnormalities were most frequent in patients with this type in comparison with patients with the focal type. Osteomas and peripheral osteomas were revealed in this type with statistical significance. Biopsy performed in one patient revealed an osteoma. These results suggest that the multiple abnormalities seen in oral X-ray examination may predict the occult existence of familial adenomatosis coli and these widespread radiopaque lesions probably represent the most extensive manifestation of FAC.

Dental infections in association with cerebral infarction in young and middle-aged men

The association between dental infections and cerebral infarction was investigated in a case-control study involving 40 patients with ischaemic cerebral infarction under the age of 50, and 40 randomly selected community controls matched for sex and age. Poor oral health, as assessed by two indices measuring the severity of infections of teeth and periodontium, or by the presence of subgingival calculus or the presence of suppuration in the gingival pockets, were more common in male patients than in male controls, but no difference was observed in females. If severe dental infections were combined with other probable bacterial infections there were altogether 16 patients (40%) but only two controls (5%) who had suffered from a probable bacterial infection within 1 month or at the time of the stroke or when examined as a control (P less than 0.01). Our results suggest an association between bacterial infection and ischaemic cerebrovascular disease in patients under 50 years of age. Severe chronic dental infection seems to be an important type of infection associated with cerebral infarction in males.

[Huneke test in the stomatologic practice]

It is a report about the "Huneke-test" based on a 30 year old experience of researching disorders in the jaw region. 334 teeth of 134 patients were tested by giving round-injections with local anaesthetic. 91 patients had a positive test result and 71 ill patients became free from trouble in different parts of the body with these injections or extractions. First of all dead teeth with an unsuspicious X-ray diagnosis were found out as causes of the disorders by means of the "Huneke-test". Examples of certain cases underline the recommendation of this test to dental practices.

Chronic extraoral fistulae of dental origin

Infections of dental origin may cause serious problems such as osteomyelitis and cutaneous fistulae. This article reviews 59 cases of extraoral fistulae of dental origin on the face and neck. The fistulae resolved after treatment of the intraoral lesion. Possible sources of such fistulae may be an obviously carious tooth, innocent-looking retained roots, or residual chronic dental infection of the maxilla or mandible.

Oral findings in Fanconi's anemia. A case report

A case of fanconi's anemia was referred to the Dental School from the Department of Pediatrics. The patient was a 24-year-old male and a product of a consanguineous marriage. His chief complaint was loose and falling teeth, which has started at the age of 16 years. The first teeth to fall out were the first permanent molars followed by mandibular and maxillary anteriors. General examination showed that the patient was of normal intelligence and small for his age. He had no palmar plantar hyperkeratosis and was not diabetic. A total of 19 teeth remained in the mouth, most of them with grade three mobility. The remaining molars and first maxillary premolars had grade three furcation involvement. Most of the teeth had periodontal pockets more than 10 mm deep. Full mouth intraoral periapical radiographs and orthopantomographic views showed severe horizontal bone loss uncommensurate with the patient's age. In view of the patient's history and severe bone loss at an early age, the diagnosis was juvenile periodontitis associated with Fanconi's anemia.

Brain abscess of odontogenic origin: report of case

Advanced dental infection rarely causes brain abscess resulting in death. Good dental hygiene and removing abscessed teeth are advised for prevention of any such occurrence. An intercranial infection is described in a 29-year-old male who also had a dental phobia.

Otalgia with a normal ear

Ear pain is a diagnostic problem when examination of the ear shows no pathology. Referred otalgia may be caused by neoplasms; dental abnormalities or infections; temporomandibular joint dysfunction; sinus, pharyngeal or salivary gland infections; temporal arteritis; cervical arthritis, or one of the neuralgias. Ear pain may also be psychogenic.

Hearing and neurologic impairment: insult timing indicated by primary tooth enamel defects

The association between hearing loss, neurologic impairment, and primary tooth enamel defects was examined in a group of 88 children presenting for hearing evaluation at a tertiary care children's hospital. Forty-one had classifiable enamel defects, reflecting the time and duration of prenatal or perinatal insult. Hearing loss was more prevalent and severe in 19 children with enamel defects of the incisal tooth edge (mean = 61 dB) reflecting a systemic insult at 14 to 16 weeks gestation, than in 7 children with cervical third tooth defects (mean = 23 dB) reflecting insult near term (X2 = 4.08; p less than 0.05). Audiometric findings among the 15 children with incisor defects of the middle third varied; 7 had significant hearing loss and 8 were normal. A correlation was observed between severity of hearing loss (in dB) and estimated time of systemic insult (in weeks gestational age) determined by tooth defect site (r = -0.48; p less than 0.01). The neurologic data revealed similar trends. The group with early systemic insults more frequently had moderate or severe neurologic deficits known to originate early in fetal development. The two groups with third trimester or term insults tended to have mild or no neurologic impairment. A differential susceptibility for developing auditory and neurologic structures based on insult timing is supported.
