Evaluation of characteristics of periodontal probes

Aim: This study aimed to evaluate the millimeter distances and active tip diameters of different periodontal probes. Methods: Two types of periodontal probes were analyzed (North Carolina (15-UNC) and PCP-12). Two manufacturers were selected for each probe type. Digital images of the probes were obtained and the distances were measured using a software program. The diameter of the active tip was measured using a digital caliper. Both variables were measured by two trained and calibrated examiners. The data were analyzed using the Bland-Altman method and two-way ANOVA with Tukey's post-hoc test. Statistical significance was set at p<0.05. Results: A comparison of measurements between the 15UNC and PCP-12 probes showed a significant difference in all millimeter markings. The 15-UNC probe showed differences between the 3 and 12 mm markings. The PCP-12 probe only showed differences between the marks at the 12 mm mark. The 15-UNC probe had a similar active tip diameter between the two manufacturers. The PCP-12 probe showed a significant difference between the two manufacturers. Both types of probes had similar active tip diameters when compared by the two manufacturers. Conclusion: There was no standardization in relation to millimeter marks and tip diameters of the two types of periodontal probes produced by the two different manufacturers. The probe types exhibited little variability

Papila interdental: previsibilidade das técnicas reconstrutivas / Interdental papilla: predictability of reconstructive techniques

A perda da papila interdental pode causar alterações fonéticas, impactação alimentar e desconforto estético. A etiologia é multifatorial, podendo ou não estar associada às doenças periodontais. Quando a causa não é proveniente de doenças periodontais, a regeneração tem maiores chances de sucesso, mas para solucionar casos em que ocorre a perda de inserção, muitas técnicas cirúrgicas foram propostas para induzir a regeneração da papila interdental, porém, com resultados limitados. O objetivo deste estudo foi revisar as possíveis causas da perda de papila interdental e analisar as diferentes técnicas propostas atualmente para a sua reconstrução. Considerando que a maioria dos estudos encontrados é sobre relatos de casos, conclui-se que são necessários estudos clínicos controlados para determinar a eficácia das técnicas cirúrgicas propostas

The loss of interdental papilla may cause phonetic changes, food impaction and a esthetic discomfort. The etiology is multifactorial, and may or may not be associated with periodontal diseases. When the cause is other than bone loss, regeneration has greater chances of success. Many surgical techniques have been proposed to induce the regeneration of the interdental papilla with limited success. The aim of this study was to review and analyze the possible causes of interdental papilla loss and the different techniques currently proposed for its reconstruction. Since most of the studies are case reports, it can be concluded that controlled clinical trials are needed to determine the efficacy of the surgical techniques used for this purpose
