Racial variations in dental procedures: the case of root canal therapy versus tooth extraction.

BACKGROUND: Racial disparities have been widely documented in medical care, but variations in dental care have not been well examined. OBJECTIVES: To determine if there is racial variation in use of root canal therapy versus tooth extraction across different levels of dental insurance coverage and adjusting for other factors known to influence treatment decisions. METHODS: Within 3 different categories of insurance coverage, we examined whether there were racial differences in the provision of the tooth-sparing treatment of root canal therapy (vs. tooth extraction) among 54,423 users of outpatient Veterans Affairs dental care in 1998. Regression analyses adjusted for the severity of tooth- and gum-related disease, age, sex, medical and psychiatric comorbidities, prior use of preventive dental services, tooth extraction and root canal therapy, and clustering by geographic region. RESULTS: In the adjusted regression models, black patients and those with unknown race were less likely overall to receive root canal therapy than whites, whereas Asians were more likely. Among patients with eligibility for continuing and comprehensive dental care, blacks were less likely and Asians more likely to receive root canals than whites. For patients covered only for emergency dental care, Hispanics had a higher likelihood of receiving root canal therapy. Among all other types of coverage, there were no significant racial differences in the care received. CONCLUSION: We observed substantial racial variations in the provision of root canal therapy among patients treated in Department of Veterans Affairs dental clinics. Future research should identify the causes of such variations.

Therapy-resistant foreign body giant cell granuloma at the periapex of a root-filled human tooth.

Although the primary etiological factor of periapical lesions is microbial, there are other independent factors that can adversely affect the outcome of endodontic treatment. In this communication, we present morphological evidence in support of the role of a foreign body reaction of periapical tissue to root-filling materials. The specimen consisted of a surgical biopsy of an asymptomatic periapical lesion which persisted after a decade of postendodontic follow-up. The biopsy was processed for correlated light and electron microscopy and was analyzed by various microtechniques. The unique feature of the lesion was the presence of vast numbers of large multinucleated cells and their cytoplasmic inclusion bodies. Morphologically, these multinucleated cells resembled foreign body giant cells. They contained characteristic birefringent cytoplasmic inclusions which on electron-probe X-ray microanalysis consistently revealed the presence of magnesium and silicon. The magnesium and silicon are presumably the remnants of a root-filling excess which protruded into the periapex and had been resorbed during the follow-up period. These observations strongly suggest that in the absence of microbial factors, root-filling materials which contain irritating substances can evoke a foreign body reaction at the periapex, leading to the development of asymptomatic periapical lesions that may remain refractory to endodontic therapy for long periods of time.

Orthodontic movement of a horizontally fractured tooth: a case report.

Intra-alveolar root fractures are relatively uncommon, and sometimes may be healed without treatment. Diagnosis of intra-alveolar root fracture is frequently made by exclusion of clinical signs of other traumatic injury, and by radiographic examination with films taken at different tube angulations. This case report presents a horizontal root fractured tooth that was healed satisfactory without treatment and moved orthodontically after prolonged time from trauma.

Treatment of external inflammatory root resorption after autogenous tooth transplantation: case report.

This paper describes a case of autogenous tooth transplantation. An external inflammatory root resorption developed in a 30-year-old female patient and was successfully treated with the placement of calcium hydroxide-based intracanal dressings. Autotransplantation of tooth 32 into the extraction socket of tooth 30 was carried out with no intraoperative complications and uneventful postoperative course. However, the patient did not appear on the 14th postoperative day to initiate endodontic therapy of the transplanted tooth. She did not return for 3 months, at which time the clinical and periapical radiographic examinations revealed the presence of external inflammatory root resorption. Endodontic treatment was initiated immediately. Root canals were prepared and filled with a calcium hydroxide-based intracanal dressing (Calen paste), changed every 21 days during a 6-month period, and were thereafter obturated with Sealapex calcium hydroxide-based sealer and gutta-percha points. After 2 years of follow-up, the transplanted tooth was symptom free with no exacerbated sensibility to percussion, normal mobility, occlusion, and masticatory function. Probing revealed no periodontal pockets or other pathological signs. Radiographic examination showed the periradicular area with normal appearance, completely healed resorption areas, and presence of an intact lamina dura.

[Surface changes of enamel, root cementum and fillings after treatment with tooth cleaning instruments].

The effect of new, automatic tooth cleaning instruments on tooth surface and surfaces and margins of amalgam and composite fillings were studied by profilometric measurements and SEM and compared with each other. On the surfaces of teeth and fillings, in particular at the margins, ultrasound treatment resulted in the significantly highest maximum roughness values. These values were lower when turbin-operated scalers were used. Results demonstrate that during tooth cleaning direct contact between ultrasound and turbine-operated scalers and tooth and filling surfaces should be prevented.
