- Bolton ratios in Portuguese subjects among different malocclusion groupsPublication . Machado, Vanessa; Botelho, João; Pereira, Dinis; Vasques, Mariana; Fernandes-Retto, Paulo; Proença, Luís; Mendes, José João; Delgado, AnaBACKGROUND: Several methods have been described to estimate inter-arch tooth size relationship, such as Bolton's ratios. The aims of this study were to verify the validity of Bolton indexes in a sample of untreated Portuguese subjects based on Angle classification and to evaluate the gender difference. MATERIAL AND METHODS: 168 pre-treatment dental casts of orthodontics Portuguese subjects (59 males and 109 females) with different occlusions were used, which were selected randomly from 541 consecutively treated orthodontic patients. The mesiodistal widths from first molar to first molar were measured on each pre-treatment cast to the nearest 0.01 mm using digital caliper, and Bolton's anterior and overall ratios were calculated. Descriptive statistics as mean, standard deviation and range were calculated. Moreover, the results were compared to Bolton's ratios and differences based on gender and occlusion groups were evaluated by statistical inference methods. RESULTS: The results reveal that the mean values, standard deviation and range were larger than Bolton's in normal occlusion group (78.3±3.5% in anterior ratio and 92.1±2.2% in overall ratio) and there were no differences between genders (p >0.05). Class I (anterior and overall ratios, p=0.001 and p<0.001, respectively), Class II/2 (anterior ratio, p=0.032) and Class III (overall ratio, p=0.041) were significantly different from Bolton's reference data. CONCLUSIONS: The results showed no differences between gender and no difference between normal occlusion and malocclusion groups. Moreover, in normal occlusion group, the anterior and overall tooth size ratios was equivalent to the original Bolton's ratios, although the mean and standard deviation were large.
- Cloud‐based collaboration and productivity tools to enhance self‐perception and self‐evaluation in senior dental students: A pilot studyPublication . Botelho, João; Machado, Vanessa; Proença, Luís; Rua, João; Delgado, Ana; Mendes, José JoãoCONTEXT: Web/cloud-based collaborations have been successively used in several educational and clinical settings with very satisfactory results against the traditional background. In this study, we assess the usefulness, ease of use, ease of learning and satisfaction of a cloud-based clinical progression practice record comparing to a traditional paper practice record. METHODS: In this cross-sectional forty senior dental students answered a USE-Questionnaire on the traditional paper book versus a digital clinical book assembled with Google Docs. They were asked about usefulness, ease of use, ease of learning and satisfaction of both gears. RESULTS: There were an absolute agreement in all four different dimensions, with the cloud-based digital system evidencing more advantages and preference from the users' perspective in usefulness (from P = 0.002 to P < 0.001), ease of use (from P = 0.034 to P < 0.001), ease of learning (P < 0.001) and satisfaction (from P = 0.001 to P < 0.001). CONCLUSION: The results of this study suggest that a digital clinical book, using free cloud-based collaboration tools, is more useful, easier to use and learn and more satisfactory than a traditional paper recording system. Also, this cloud-based collaboration system presents characteristics that may guide future clinical research.

- Orthodontic smile: a new categorization of the perfect smilePublication . Dias, Maria do Rosário; Ferreira, Ana; Pires, Maria Calejo; Alves, Valter; Delgado, AnaBackground and Aim: There is a shortage of empirical studies that combine the problem of malocclusion to the importance of the self-perception of the mouth/smile in the mental representation of the self-image of the face, which is the aim of the present qualitative and exploratory study. Subjects and Methods: The convenience sample consisted of 151 children and youngsters of both genders, aged 8–24 years, who used an orthodontic appliance for 6 months to 1 year, and were invited to draw two portraits of their mouth/smile before (M1) and after (M2) the use of an orthodontic appliance. Results: The main reasons that underpin the use of an orthodontic appliance are defined by the crooked teeth correction, malocclusion correction, and interdental spaces categories, in which having the perfect smile was only relevant to preteens. Discussion and Conclusions: In the present study, we have identified the orthodontic smile as a new categorization of a perfect smile associated with the social display of a look with perfect teeth.

- Stress, salivary cortisol and periodontitis : a systematic review and meta-analysis of observational studiesPublication . Botelho, João; Machado, Vanessa; Mascarenhas, Paulo; Rua, João; Alves, Ricardo; Cavacas, Maria Alzira; Delgado, Ana; Mendes, José JoãoObjective: This meta-analysis aims to systematically assess whether periodontitis has a meaningful effect on salivary cortisol, reflecting changes on free blood cortisol levels. Design: The Cochrane Handbook and the PRISMA statement were used as reporting guidelines. The MEDLINE-PubMed, Google Scholar, EMBASE, and CENTRAL databases were searched until September 2017 to identify eligible studies, screened by seven independent authors and verified by an eighth. Studies comparing salivary cortisol level of periodontitis cases to controls were included. Data were extracted using a predefined table and since all papers were non-randomized clinical trials they were appraised using Downs and Black tool. DerSimonian random effects meta-analysis was performed using OpenMetaAnalyst. Results: Six cross-sectional studies were included, with 258 participants with chronic periodontitis and 72 with aggressive periodontitis, in a total of 573 participants. Overall results showed that aggressive periodontitis patients have, on average, 53% higher salivary cortisol levels than healthy controls 1.53 (1.11–2.12). Meta-regression exploring the relationship among salivary cortisol levels and periodontal measures, i.e., periodontitis severity, showed a global neutral effect, although this result requires future confirmation due to the low power of the model. Conclusion: Observational studies results suggest that subjects with aggressive periodontitis have higher salivary cortisol levels than healthy ones or patients with chronic periodontitis. Such salivary cortisol response difference may have a negative impact on the periodontium, contributing to worse the burden of aggressive periodontitis disease. In the future, wide and well-designed longitudinal studies should be carried out in order to extensively confirm this possible effect, considering the complex nature of periodontitis and its many confounders factors that may contribute to this outcome.
