Evaluation of the impact of alveolar bone graft surgery on the nasal cavity of individuals with cleft lip and palate
Cleft lip and palate are the most common congenital malformations in the craniofacial region, occurring at a rate of 1:700 births in Brazil. These conditions lead to functional impacts on patients, such as changes in breathing, teeth, speech, chewing, swallowing and sucking. Treatment begins with primary surgeries, including lip and palate repair, which aim to reconstruct the soft tissues. Secondary alveolar bone grafting (SABG) reconstructs the bone defect in the cleft region, with the main goal of supplying bone tissue to the cleft region and restore the continuity of the alveolar process. To measure the changes in cross-sectional areas (CSAs) and nasal volume in patients and their impact on the nasal cavity (NC) in the two-month postoperative period (PO2M).
Biomimetic Restorative Dentistry: an evidence-based discussion of common myths
This narrative review critically examines some protocols of biomimetic restorative dentistry (BRD), which supposedly outperforms traditional adhesive techniques. This review explores the origins of BRD, introduces cognitive biases influencing the adoption of BRD protocols without evidence scrutiny, and discusses nine BRD protocols. For this, we searched randomized clinical trials and systematic reviews in the literature on the PubMed, Embase, and Cochrane Library CENTRAL databases, which lead to the following conclusions about the revised protocols: 1) The use of dyes excessively removes carious dentin; 2) Aluminum oxide air abrasion contributes to overtreatment and may pose long-term health risks to dental professionals; 3) Beveling enamel in posterior teeth is technically difficult and leads to unnecessary loss of adjacent sound enamel with no evidence of its use outperforming butt-joint preparations; 4) Deactivating matrix metalloproteinases with chlorhexidine shows no clinical evidence of improving restoration longevity. 5) "Elected" gold-standard adhesive systems perform no better than other good performing available systems; 6) Immediate dentin sealing and resin coating result in similar post-operative sensitivity and longevity of indirect fillings as delayed dentin sealing; 7) Deep margin elevation is a viable alternative to manage subgingival margins in occlusoproximal cavities; 8) The process of "decoupling" with time lacks scientific evidence to support its use; 9) Placing fiber inserts on the pulpal floor and/or axial wall to minimize stress offers no benefits over current alternatives. In conclusion, more rigorous research is needed to validate BRD protocols, focusing on important clinical outcomes that impact in the longevity of the restoration, such as fracture, debonding, post-operative sensitivity, esthetic quality, presence of caries lesions adjacent to restorations and patients' satisfaction need to be thoroughly investigated. Reliance on anecdotal evidence, clinical experience, and common sense propagates myths and undervalues the need for a critical approach in evaluating dental techniques.

1,25(OH)2D3 increase osteogenic potential of human periodontal ligament cells with low osteoblast potential
Periodontal dental ligament mesenchymal stem cells (PDLMSCs) play a major role in periodontal tissue regeneration by the neoformation of root cementum and alveolar bone. These cells are highly heterogeneous, and many present low potential to renovate the hard tissue damaged by periodontal disease. A previous study found that the low osteoblast/cementoblast (O/C) differentiation potential of PDLMSCs is related to high asporin (ASPN) expression, which was identified as a negative regulator of PDL cells differentiation and mineralization, suppressing BMP-2-induced O/C differentiation. This study aimed to investigate whether 1,25(OH)2D3 treatment could stimulate the O/C differentiation of periodontal ligament mesenchymal progenitor cells characterized as low osteoblast potential (LOP), by asporin and bone morphogenetic protein-2 alteration.
The effect of calcium hydroxide and double antibiotic paste on radiographic outcomes and periapical MMP-8 levels in regenerative endodontic procedures: a randomized clinical trial
The primary goal is to evaluate the effects of two different intracanal medicaments, calcium hydroxide [Ca(OH)2] and double antibiotic paste (DAP), on radiographic outcomes during regenerative endodontic procedures (REP) of immature permanent mandibular first molars with symptomatic irreversible pulpitis and symptomatic apical periodontitis (SIP/SAP). Additionally, the secondary goal was to evaluate MMP-8 levels during REP using two different intracanal medicaments.
Implications of the health information pollution for society, health professionals, and science
In the era of ultra-connectivity, the proliferation of speculative notions driven by personal emotions eclipses the credibility of scientific evidence. This trend has led to an alarming surge in information pollution, particularly by the pervasive influence of social media platforms. Consequently, this overflow of falsehoods poses a significant threat to public health and overall societal well-being. In this sense, this critical review aims to present the harmful impacts of the health information pollution on society, health professionals, and health science, as well as strategies for their mitigation. The management of information pollution requires coordinated efforts to develop and implement multiple effective preventive and debunking strategies, such as the regulation of big tech companies' actions and algorithm data transparency, the education of health professionals on responsible social media use, and the establishment of a novel academic culture, shifting from the valorization of productivism to socially relevant scientific production. By acknowledging the complexities of this contemporary issue and drawing insights from distinct perspectives, it is possible to safeguard the integrity of information dissemination and foster a more informed and resilient community.
Bleaching as a complement to fluoride-enhanced remineralization or resin infiltration in masking white spot lesions
