The anterior buccal mandibular depression: physical and radiologic features.

The anterior buccal mandibular depression (ABMD), an anatomic variation not previously mentioned in the dental literature, is considered. Its physical and radiologic configuration is evaluated, and its significance in the differential diagnosis of radiolucent lesions in the anterior portion of the mandible is discussed. The general prevalence of ABMD was found to be 19.8%, with a significantly higher prevalence in children (p less than 0.001). In the majority of cases, the depression was radiologically detected. The radiopacity of the area was significantly dependent on depth of the depression (p less than 0.001). The radiographic image of the ABMD resembles, in many cases, the image of the less common anterior lingual salivary gland depression. The relatively high frequency of the ABMD indicates the importance of recognizing its radiologic features.

The anterior buccal mandibular depressions: ontogeny and phylogeny.

The frequency of an anterior buccal depression in the mandible (ABMD), or a mental fossa, is reported on 970 human mandibles of various groups and different ages, as well as in 38 mandibles of nonhuman primates. The ontogenetic and phylogenetic significance of the results relevant to development of a chin in Homo sapiens is discussed. The ABMD is also compared with the occurrence of a lingual mandibular depression.

Migratory stomatitis.

Migratory stomatitis is a unique oral condition with several descriptive names. The diagnosis is based on the clinical appearance and the history of the lesions. The etiology of this entity is still open to debate. A review of the literature and a clinical description of a study group consisting of seven additional cases, in which long-term follow-up was done, are presented. Migratory stomatitis is suggested as the most suitable term to describe accurately the nature and the behavior of this condition.

Efficiency of the cervical lead shield during intraoral radiography.

The cervical lead shield was compared with the conventional lead apron with regard to efficiency of protection against radiation during a full-month survey (fourteen periapical and two bitewing radiographs). The study was performed on a Temex tissue-equivalent human phantom, and thermoluminescent dosimetry was used to measure radiation absorption in the ovaries, testes, and thyroid gland areas. Results showed that the cervical shield significantly reduces the amount of radiation to the skin in all three areas and is equally as effective as the combination of lead apron and thyroid shield. It is therefore recommended as a protective measure during intraoral radiography.

Relationship between the apices of the lower molars and mandibular canal--a radiographic study.

The study was performed on forty-six randomly chosen dry mandibles. The molar areas of each mandible were radiographed by the paralleling technique, and an additional radiograph at -20 degrees angulation of the same area was taken. Measurements of the distance between the upper border of the mandibular canal and the root apices of the first and second molars were taken. The location of the mandibular canal in the buccolingual plane was determined. The obtained data were statistically evaluated. Statistically significant symmetry of the relationship of the mandibular canal to the root apices was established between the right and left sides of the same mandible. In the majority of cases the mandibular canal was buccal to the apices of the second molar, and in the first molar area the canal was lingual to the root apices in almost half of the cases. Most frequently, the upper border of the mandibular canal was located 3.5 to 5.4 mm below the root apices of both first and second molars. In no case was the mandibular canal found in close proximity, both in the vertical and in the buccolingual planes, to the first and second molar apices.

New concept in chemoprophylaxis of bacterial endocarditis resulting from dental treatment.

Bacteremia following dental procedures may lead to bacterial endocarditis in susceptible patients. Traditional methods of chemoprophylaxis with a parenteral loading dose of penicillin followed by oral penicillin have proved impractical outside the hospital. In 1978, it was suggested in England that amoxicillin be substituted as the drug of choice in the prophylaxis of bacterial endocarditis. The recommended mode of treatment was a single oral dose of 3 g amoxicillin administered 1 hour before onset of the dental procedure. Amoxicillin is absorbed to a greater extent and more rapidly than penicillin V. It maintains its effectiveness throughout the critical postoperative period at concentrations well over the minimum necessary to combat Streptococcus viridans. Amoxicillin has two mechanisms of protection: bactericidal and inhibition of bacterial adherence to the thrombotic vegetation on injured heart valves. Data obtained from 206 susceptible patients undergoing dental treatment under chemoprophylaxis with amoxicillin showed that in no case did infective endocarditis occur. Only in 13.1% of the patients could very mild side effects of this drug be observed. With this new method, there is a higher incidence of patient compliance and administration is easier to supervise.
