Efficacy of an anesthetic gel in the reduction of pain during impression making.

INTRODUCTION: Gingival tissue displacement can be an uncomfortable procedure, often performed without injectable local anesthesia. The present study evaluated the efficacy of an anesthetic gel in reducing pain during this procedure. MATERIAL AND METHODS: Thirty patients undergoing definitive dental impression, for fabricating full-coverage restorations, were evaluated for pain perception on displacement of the surrounding gingival tissues. All the participants were randomly divided into two groups. Five minutes before the insertion of the displacement cord, the anesthetic gel, a mixture of 5% lidocaine and 5% prilocaine, was applied in the sulcus of test group patients. Each patient was asked to complete the Visual Analogue Scale (VAS) and the Verbal Rating Scale (VRS). RESULTS: In the two scales considered, test group patients showed a statistically significant pain reduction (VAS p=0.0002, VRS p=0.01054) compared to control group patients. CONCLUSIONS: Within the limitations of this study, a clinically significant efficacy of the anesthetic gel was noticed during gingival displacement procedures.

Relationships between different tooth shapes and patient's periodontal phenotype.

BACKGROUND AND OBJECTIVE: The purpose of the present study was to establish whether any correlation exists between tooth shapes and patient-related factors such as gingival and periodontal characteristics. MATERIAL AND METHODS: Clinical measurements, including the width and the height of maxillary central incisor crowns, the apico incisal height of the keratinized mucosa (KM), the buccal gingival thickness (GT), the depth of the sulcus (SD), the bone-sounding depth (BS) and the height of the interproximal maxillary central papilla (Ph), were investigated in 50 healthy individuals. These individuals were then divided into three groups based on the shape of their maxillary central incisor crowns: triangular; square; or square-tapered. The three groups were analyzed to determine any significant differences among the groups in the values obtained for clinical measurements. RESULTS: There were no significant differences among the three groups in terms of the SD (p = 0.11) or the BS (p = 0.54), whilst statistically significant differences were observed for the KM (p < 0.001), the GT (p = 0.012) and the Ph (p < 0.001). CONCLUSION: The results of this study indicate that different tooth shapes are associated with significantly different values for the extent of the KM, its bucco-lingual thickness and the height of the interproximal maxillary central papilla.

Estudo comparativo e aberto sobre a eficacia e a tolerabilidade da azitromicina vs amoxilina em rinossinusites agudas em adultos / Open comparative study of the efficaccy and tolerability of azithromycin versus amoxycillin in the treatment of acute rhinosinusitis

A azitromicina e um antibiotico azalideo que penetra muito bem em tecido respiratorio e possui um prefil farcocinetico unico,que permite a sua administracao uma vez ao dia por apenas tres dias.Seu amplo espectro de acao inclui gram-positivos,gram-negativos e patogenos respiratorios atipicos.O presente estudo foi realizado para comparar a azitromicina(500mg,uma vez ao dia por tres dias)com a amoxicilina(500mg,tres vezes ao dia,por 14 dias de rinossinusites agudas em individuos adultos.Os dados demograficos dos pacientes randomizados para azitromicina(n=63) e amoxicilina(n=63) foram estatisticamente equivalentes.No dia 15,45 pacientes foram avaliados no grupo tratado com azitromicina e 46 pacientes foram avaliados no gupo tratado comamoxicilina,uma resposta favoravel(cura mais melhora)foi relatada em 96 por cento dos casos para ambos os grupos de tratamento,com somente um paciente apresentando recaida no grupo da azitromicina.As taxas de respostas favoraveis foram de 100 por cento para os pacinets tratados com azitromicina e 83 por cento para os pacinets tratados com amoxicilina(p =0,006)no dia 30.Nenhuma diferenca significante em relacao a eficacia bacteriologica foi obsercada no dia 15 ou dia 30 entre os dois grupos de tratamento.O tratamento foi considerado como muito bom ou bom por 93,5 por cento dos pacientes tratados com azitromicina comparado com 80 por cento daqueles que receberam amoxicilina(p menor 0,05)Sete pacinetes no grupo da azitromicina e 18 pacientes no grupo da amoxicilina relataram eventos adversos dos quais 3 e 13,respectivamente,foram considerados relacionados ao tratamento.Em ambos os grupos de tratamento a diarreia foi o evento adverso mais frequente relatado.Neste estudo a azitromicina foi efetiva mais significante e melhor tolerada quando comparada a amoxicilina
