Dental complications of herpes zoster: Two case reports and review of literature.

Herpes zoster (HZ) (shingles) results due to reactivation of varicella‑zoster virus. Unusual dental complications like osteonecrosis, exfoliation of teeth, periodontitis, and calcified and devitalized pulps, periapical lesions, and resorption of roots as well as developmental anomalies such as irregular short roots and missing teeth may arise secondary to involvement of 2nd or 3rd division of trigeminal nerve by HZ. Such cases pose both a diagnostic as well as a therapeutic challenge. We report two such rare dental complications of HZ‑spontaneous tooth exfoliation and osteonecrosis of the maxilla in a 70‑year‑old female patient; and multiple periapical pathoses affecting right half of the mandibular teeth in a 45‑year‑old female patient. Both the patients did not have any associated systemic illness. The aim of this paper was to compare the present cases with all the 46 cases of osteonecrosis and 6 cases of multiple periapical pathoses secondary to trigeminal zoster reported in literature till date The article also throws light that the occurrence of such dental complications of HZ is not entirely dependent on the immune status of the host.

Chediak-Higashi Syndrome and Premature Exfoliation of Primary Teeth

The Chediak-Higashi syndrome (CHS) is a rare hereditary fatal disease, if not treated. These changes are associated with various diseases and syndromes that mainly cause periodontal disease and thus the premature loss of teeth. This paper describes the monitoring of premature loss of primary teeth that began when the child was 5 years old. On presentation his teeth were mobile and there was a history of gingival bleeding. Panoramic radiography revealed generalized and severe bone loss, and the teeth showed no bony support enough for their stability. Blood test was ordered to assess the overall health of the child and giant cells with cytoplasmic granules were found, confirming the diagnosis of CHS. The management of periodontal disease focused on the control of infection and bacterial plaque by mechanical and chemical methods.

A síndrome de Chediak-Higashi (CHS) é uma doença rara hereditária e fatal se não for tratada. Estas alterações estão associadas com várias doenças e síndromes que, principalmente, causa a doença periodontal assim como perda prematura de dentes. Este artigo descreve o monitoramento de perda prematura de dentes decíduos, que começou quando a criança tinha 05 anos. Na apresentação os dentes estavam com mobilidade e apresentava sangramento gengival. As radiografias panorâmicas revelaram perda óssea generalizada e grave, e os dentes sem suporte ósseo suficiente para a sua estabilidade. Foi realizada o exame de sangue para avaliar a saúde geral da criança no qual foi encontrado células gigantes com grânulos citoplasmáticos, confirmando o diagnóstico de CHS. O tratamento da doença periodontal por meio de métodos mecânicos e químicos são necessários para controle da infecção e da placa bacteriana.

Fibroma en el reborde alveolar en una niña de cinco meses: reporte de un caso y revisión de la literatura / Fibroma of the alveolar ridge in a five-month-old girl: report of a case and review of the literature

Se hace el reporte de un caso de fibroma traumático en el reborde alveolar en una niña de cinco meses. La aparición de la lesión está en estrecha relación con la exfoliación espontánea de dientes neonatales y el hábito de succión del pulgar

Caries dentaria y exfoliación ósea / Dental caries and bone exfoliation

Se consigna en este trabajo el viejo concepto de que el diente es un hueso, tal como lo aseveran los maestros dentistas del siglo XVIII. Como dice el autor "a las caries dentarias corresponde la caries ósea, fenómeno denominado exfoliación". El Dr. Vidal cita a los más elocuentes testimonios de esa época, que refirma en las numerosas referencias aclaratorias de este magnífico trabajo
