- Association between dietary inflammatory index and periodontitis: a cross-sectional and mediation analysisPublication . Machado, Vanessa; Botelho, João; Viana, João; Pereira, Paula; Lopes, Luísa Bandeira; Proença, Luís; Delgado, Ana Sintra; Mendes, José JoãoInflammation-modulating elements are recognized periodontitis (PD) risk factors, nevertheless, the association between dietary inflammatory index (DII) and PD has never been appraised. We aimed to assess the association between DII and PD and the mediation effect of DII in the association of PD with systemic inflammation. Using the National Health and Nutrition Examination Survey 2009–2010, 2011–2012 and 2013–2014, participants who received periodontal exam and provided dietary recall data were included. The inflammatory potential of diet was calculated via DII. PD was defined according to the 2012 case definition. White blood cells (WBC), segmented neutrophils and C-reactive protein (CRP) were used as proxies for systemic inflammation. The periodontal measures were regressed across DII values using adjusted multivariate linear regression and adjusted mediation analysis. Overall, 10,178 participants were included. DII was significantly correlated with mean periodontal probing depth (PPD), mean clinical attachment loss (CAL), thresholds of PPD and CAL, WBC, segmented neutrophils and DII (p < 0.01). A linear regression logistic adjusted for multiple confounding variables confirmed the association between DII and mean PPD (B = 0.02, Standard Error [SE]: 0.02, p < 0.001) and CAL (B = −0.02, SE: 0.01, p < 0.001). The association of mean PPD and mean CAL with both WBC and segmented neutrophils were mediated by DII (from 2.1 to 3.5%, p < 0.001). In the 2009–2010 subset, the association of mean CAL with serum CRP was mediated by DII (52.0%, p < 0.01). Inflammatory diet and PD may be associated. Also, the inflammatory diet significantly mediated the association of leukocyte counts and systemic inflammation with PD.
- Children’s attitudes and behaviors about oral health and dental practicesPublication . Fernandes, Sara Costa; Louceiro, Ana; Lopes, Luísa Bandeira; Esteves, Francisco; Arriaga, PatríciaThe present study sought to contribute to a better understanding of children’s attitudes and behaviors regarding oral health and dental practices. The sample was composed of 101 children (8–10 years), collected from several schools in the Lisbon metropolitan area. Our main goals were to collect a survey of information about the beliefs, attitudes, habits and knowledge of children about oral and dental issues in order to not only have an overview of them but also to serve as a basis and a starting point for the development of intervention programs to increase positive attitudes and behaviors related to oral health and promote greater knowledge about these subjects. In general, children reported positive behaviors regarding dental habits and oral hygiene practices. Children’s opinions and beliefs about dentists were also globally positive; however, the results suggested that younger children reported more positive attitudes, emotions and previous experiences. Regarding children’s knowledge about these dental issues, the results were quite negative and worrying, ruled by ignorance and incorrect beliefs and behaviors. In sum, all the results and conclusions of this study may contribute to the development of educational programs within the scope of the promotion of oral health and hygiene practices—“An Adventure about Oral Health.”
- A four-year follow-up case report of hypomineralized primary second molars rehabilitated with stainless steel crownsPublication . Lopes, Luísa Bandeira; Machado, Vanessa; Botelho, JoãoHypomineralized primary second molars (HPSM) are characterized by enamel opacities accompanied by hypersensitivity and atypical caries lesion, on one to four primary second molars. The correct treatment and follow-ups of those teeth have an important impact on a correct eruption of the first permanent molars and future occlusion. Hence, this report aims to describes a case of a severe HPSM in all second molars of a four-year-old girl and subsequent four-year follow-ups. The rehabilitation involved the placement of four stainless steel crowns on all four second primary molars under general anesthesia. Concerning the available literature and the case severity of HPSM, the treatment approach proposed for the case provided good functional outcome.
- Management of an unsuccessful regenerative endodontic procedure after tooth fracture: a case reportPublication . Lopes, Luísa Bandeira; Paredes, Francisco; Pimenta, Andreia; Carpinteiro, InêsDental trauma is a very frequent occurrence in children and adolescents, which creates a great impact on the esthetics, functions, and phonetics. Traumatic dental injuries can range from simple enamel fractures to permanent tooth loss. This case report presents an eight-year-old patient with an uncomplicated crown fracture of tooth 21, and 30 days after trauma, it was diagnosed as necrotic pulp. The first treatment choice was a regenerative endodontic procedure (REP), however, the failure led to apexification with Mineral Trioxide Aggregate (MTA). The chosen rehabilitation was a composite veneer. Concerning the available literature and fracture enamel dentin, the treatment approach proposed for the case provided good functional and esthetic outcomes.
- Oral and dental abnormalities caused by a pediatric rhabdomyosarcoma tumor treatment: a clinical case reportPublication . Lopes, Luísa Bandeira; Themudo, Rodrigo; Botelho, João; Machado, VanessaRhabdomyosarcoma is one of the most common soft-tissue sarcomas in children. The therapy for this condition has evolved significantly over recent decades, as has survival rates. Nevertheless, multiagent chemotherapy, radiation therapy, surgical resection or a combination of these modalities still have to be performed. This case report presents a 16-year-old boy with oral and dental effects after rhabdomyosarcoma treatment, diagnosed at the age of 4 years old. This report highlights the key role of dentists in the clinical management of rhabdomyosarcoma cases before, during and after treatment, and its potential side effects.
- Severe case of delayed replantation of avulsed permanent central incisor: a case report with four-year follow-upPublication . Lopes, Luísa Bandeira; Botelho, João; Machado, VanessaAvulsion is one of the most serious dental traumatic injuries with a reserved prognosis. This case report describes multiple trauma lesions in permanent central incisors of an eight-year-old girl and a four-year follow-up. The right upper incisor suffered avulsion, remained 16 h extraorally, and was replanted after extraoral endodontic therapy. The left maxillary central incisor suffered a noncomplicated crown fracture with concomitant subluxation. The present case adds to the literature a rare occurrence of success in a severe case with poor prognosis. For this reason, the International Association for Dental Traumatology (IADT) guidelines should be followed and, even in extreme situations, replantation should always be considered.
