1/4. Adverse reactions associated with the use of eugenol in dentistry.

    eugenol is a material commonly used in dentistry with few reported side effects. It is not however, a bio-friendly material when in contact with oral soft tissues. It can produce both local irritative and cytotoxic effects, as well as hypersensitivity reactions. Here we report on two cases of adverse local reaction to eugenol, contained within a temporary restorative material and a temporary cementation material respectively, which illustrate these problems.

2/4. methotrexate and oral ulceration.

    methotrexate is well established in the drug treatment of various neoplastic diseases. More recently it has become increasingly used as a once-weekly, low-dose treatment of disorders such as psoriasis and rheumatoid arthritis. Clinical trials have shown its effectiveness in these conditions and it is likely that dentists will encounter patients taking this drug in general dental practice. Oral ulceration can occur as a side effect of methotrexate therapy. This may be due to lack of folic acid supplementation or overdosage due to confusion regarding its once-weekly regime. Illustrations of these problems, which have initially presented in a dental setting, are given. Important drug interactions of methotrexate relevant to dentistry are discussed.

3/4. necrosis of gingiva and alveolar bone caused by acid etching and its treatment with subepithelial connective tissue graft.

    The misuse of various chemicals in dentistry may cause damage to gingiva and alveolar bone. In this case report, we describe necrosis of the gingiva and alveolar bone caused by acid etching. A patient whose caries on the cervical third of the root of his mandibular right first molar were treated 2 days earlier presented to our clinic with severe pain and discomfort in the treated area.Intraoral examination revealed a spreading gingival ulceration and exposed alveolar bone. The patient was followed and a week later, when the gingival inflammation had decreased, periodontal surgery was performed. A full-thickness flap was raised and necrotic gingiva and bone were removed. As a result, only a narrow band of keratinized gingiva remained. To treat the gingival recession and protect the underlying bone, a subepithelial connective tissue graft was placed during the same session. After the operation, the patient"s complaints resolved. Subepithelial connective tissue graft can be an important treatment approach in cases of necrosis and gingival recession caused by the misuse of various chemicals.

4/4. Congenital insensitivity-to-pain with anhidrosis (CIPA): a case report with 4-year follow-up.

    Congenital Insensitivity-to-pain with anhidrosis (CIPA) is a rare disorder in which pain perception is absent from birth, despite the fact that all other sensory modalities remain intact or minimally impaired and tendon reflexes are present. The challenge in dentistry is to manage the self-mutilation behavior avoiding serious damages especially to oral structures, hands and fingers. A Brazilian case of CIPA is presented and discussed with clinical documentation of the oral-related problems over a 4-year follow-up. A conservative treatment (mouthguard-like appliance) was proposed with the objective to avoid full mouth extraction.
