The utilization of combined chemoradiation therapy has recently increased in the treatment of head and neck cancers. This patient population is significantly more prone to various oral complications during and after medical therapy. Oral complications and long-term effects include mucositis, xerostomia, alterations in taste, vascular compromise, mucosal thinning and increased risk of rampant caries and periodontal disease. The most serious oral complication that can arise is osteoradionecrosis. Managing patients properly prior to medical treatment can help decrease these potential complications during and after treatment. This purpose of this article is to review the different radiation and chemotherapy regimens used to treat patients with head and neck cancers, as well as protocols in the dental management of these patients before, during, and after medical treatment.

This article describes how dentists can recognize osteoporosis before fractures develop, and discusses whether osteoporosis affects tooth loss or inhibits implant osseointegration. Some success in diagnosing osteoporosis has been obtained using clinical questionnaires that attempt to identify those who have strong risk factors for the disease, and analysis of the sparse trabeculation and thinning of the mandibular cortex often seen in dental panoramic radiographs. The role of osteoporosis in periodontal disease is unclear as there are many conflicting reports, but the evidence suggests that tooth loss may be more prevalent in patients with osteoporosis.

We report a familial enamel hypoplasia in Italian Greyhounds resembling non-syndromic autosomal recessive amelogenesis imperfecta (AI) of humans. The condition uniformly affects deciduous and permanent teeth and is manifested by enamel roughening/thinning and brownish mottling. Affected teeth are often small and pointed with increased gaps. However, basic tooth structure is usually maintained throughout life, and fractures and dental cavities are not a serious problem as in humans. No tissues or organs other than teeth were affected by this mutation, and there was no relationship between enamel hypoplasia and either autoimmunity or periodontal disease, which also are prevalent in the breed. The enamel hypoplasia was associated with a 5-bp deletion in exon 10 of the enamelin (ENAM) gene. The prevalence of the enamel defect in Italian Greyhounds was 14%, and 30% of dogs with normal teeth were carriers. Genome analyses suggest that the trait is under inadvertent positive selection. Based on the deletion detected in the ENAM gene, a genetic test was developed for identifying mutation carriers, which would enable breeders to manage the trait.
