Impact of serum vitamin D levels on periodontal healing outcomes: A preliminary cohort study.

OBJECTIVE: To evaluated the relationship between serum vitamin D levels and periodontal healing outcomes in patients with mild or moderate periodontitis. METHODS: Serum vitamin D levels and periodontal pockets and gingival bleeding were evaluated in 51 patients before and 6 months after non-surgical periodontal treatment. A t-test and chi-square test were used to analyse the data (p ≤ 0.05). RESULTS: The mean reduction of periodontal pocket depth was statistically significant higher in patients with vitamin D ≥30 ng/ml than those with <30 ng/ml (CI = -0.23-0.42, p = 0.05), but not clinically significant. Vitamin D level was not associated with the percentage of sites of gingival bleeding on probing at the final evaluation (OR = 0.58, 95% CI = 0.17-1.99, p = 0.39). CONCLUSION: Lower serum vitamin D level was associated with a slightly reduced periodontal healing after non-surgical periodontal therapy, which should be further investigated in a larger population.

A importância do diagnóstico do líquen plano bucal / The importance of diagnostic of oral lichen planus

O líquen plano (LP) é uma desordem mucocutânea de etiologia ainda desconhecida, mas com evidências de associação a uma resposta imune celular mediada. Na mucosa bucal, possui várias formas clínicas, o que dificulta o seu diagnóstico. O LP é de especial interesse parao cirurgião-dentista pelo seu controverso potencial de malignização e pela possibilidade de estar associado ao vírus da hepatite C. O objetivo deste artigo é realizar uma revisão da literatura e relatar um caso clínico de líquen plano bucal (LPB), localizado em borda lateral de língua, ressaltando os aspectos clínicos e histopatológicos, importantes para o seu reconhecimento.

Lichen planus (LP) is an unknown etiology mucocutaneous disorder, thus showing evidence of association with a cell-mediated immune response. In the oral mucosa, several clinical manifestations are observed, which difficulties diagnosis. The LP is of particular interest to the dentistry practitioner due its controversial malignant potential and the possibility of being associated with hepatitis C. The aim of this article is to review and report a clinical case of oral oral lichen planus (OLP), located in tongue's lateral border, emphasizing the clinical and histopathological important for its recognition.
