The effect of chronic parathyroid extract on tooth eruption and dental tissues in osteopetrotic mice.

The grey lethal mouse is an osteopetrotic mutant in which there is diffuse sclerosis of the entire skeleton and the teeth remain trapped in the jaws. The condition was treated with daily subcutaneous injections of PTE beginning at birth. PTE induced molar tooth eruption in some mutants and improved root formation (without eruption) in others. However, the zone of predentine in the crown of the tooth remained abnormally wide and dentinogenesis remained irregular. Resorption of alveolar bone was adequate to permit complete tooth eruption in some animals and increased root formation in others.

Postradiation dental extractions without hyperbaric oxygen.

This study examined the incidence of osteoradionecrosis after tooth extraction with low-epinephrine or epinephrine-free, nonlidocaine local anesthetics and conservative surgical techniques. Estimates of the absorbed radiation dose on irradiated alveolar bone were made by reviewing radiotherapy records. This investigation included 72 patients ranging in age from 22 to 80 years (median 57.4 years). We removed 449 teeth. Analysis of radiotherapy check films revealed that only 196 teeth (44%) were included within the treatment volume. The median prescribed tumor dose was 50 Gy (range 25 to 84 Gy) in 20 fractions (range 10 to 37), with a median dose per fraction of 2.5 Gy (range 1.88 to 3.14 Gy). Follow-up time ranged from 68 days to 19.3 years (median 4.8 years). No instances of osteoradionecrosis occurred as a result of dental extraction with this conservative method.

Extraction site reconstruction for alveolar ridge preservation. Part 1: rationale and materials selection.

Alveolar ridge resorption has long been considered an unavoidable consequence of tooth extraction. While the extent and pattern of resorption is variable among individuals, there is a progressive loss of ridge contour as a result of physiologic bone remodeling. Over the long term, prosthodontic complications, loss of function, and inadequate bone for the placement of dental implants may result. Guided bone regeneration techniques and the use of bone replacement materials have both been shown to enhance socket healing and modify the resorption process. This review describes the process of alveolar bone loss, materials for extraction site grafting, and proposed mechanisms for ridge preservation.
