5-Aminolevulinic Acid Photodynamic Therapy in Cancer Treatment
5-aminolevulinic acid-photodynamic therapy (5-ALA-PDT) is a therapeutic option for a variety of cutaneous and internal malignancies. PDT uses a photosensitizer that, activated by light in the presence of molecule oxygen, forms ROS, which are responsible for the apoptotic activity of the malignant tissues. 5-ALA is usually used as an endogenous pro-photosensitizer because it is converted to Protoporphyrin IX (PpIX), which enters into the process of heme synthesis and contextually becomes a photosensitizer, radiating a red fluorescent light. PDT has the benefit of being administered before or after chemotherapy, radiation, or surgery, without impairing the efficacy of these treatment techniques. Furthermore, sensitivity to PDT is unaffected by the negative effects of chemotherapy or radiation.

Engineering Principles for Clinicians
As innovation and especially the advent of customized prostheses has deeply modified many surgical procedures in our discipline, it is imperative for the contemporary surgeon to become aware of the impact that the MDR will have on many aspects, including the choice of the manufacturer, the evaluation of the devices, point-of-care 3D printing labs, and medical software.

3D Printing of Dental Prostheses
Revolutionary fabrication technologies such as three-dimensional (3D) printing to develop dental structures are expected to replace traditional methods due to their ability to establish constructs with the required mechanical properties and detailed structures. Three-dimensional printing, as an additive manufacturing approach, has the potential to rapidly fabricate complex dental prostheses by employing a bottom-up strategy in a layer-by-layer fashion. This new technology allows dentists to extend their degree of freedom in selecting, creating, and performing the required treatments. Three-dimensional printing has been narrowly employed in the fabrication of various kinds of prostheses and implants. There is still an on-demand production procedure that offers a reasonable method with superior efficiency to engineer multifaceted dental constructs.

COVID-19's Repercussions on Oral Health
Oral manifestations related to COVID-19, including fungal infections, recurrent HSV, oral ulcerations, drug-related eruptions, dysgeusia, xerostomia or decreased salivary flow, and gingivitis, may be a result of the impaired immune system and/or susceptible oral mucosa.

Elastodontic Appliances
The term “functional appliance” refers to a lot of orthodontic appliances initially designed primarily to correct Class II malocclusion; their use received much acclaim in Europe in the 20th century but not in the USA, where Angle’s philosophy, which put in the foreground the need to achieve an ideal dental occlusion with a fixed multibrackets device, was preferred. Elastodontics, therefore, aims to solve skeletal and functional problems in the growth period. Still, at the same time, it represents an extraordinary instrument to readjust the vertical dimension in the adult patient for prosthetic purposes. Elastodontics is a new therapeutic approach that uses removable appliances made with an elastomeric material to produce light and elastic forces to correct malocclusion, aligning them and reducing potential risk factors that can affect growth. This therapy simplifies or eliminates a possible and subsequent orthodontic intervention because it facilitates balanced growth, reduces the number of extractions, and increases stability during treatment. If you change the function through the re-education of behaviour, you will also change the shape. The main purpose of the functional treatment is to “guide” the proper growth of the bone bases by stimulating the perioral muscles and neuromuscular system.

Endodontic Microsurgery
Endodontic microsurgery (EMS) aims to eradicate the sources of infection once the apical root resection removes most of the infected anatomical structures and repairs potential procedural errors in the apical region. This surgical procedure is characterized by the use of an operating microscope which improves illumination and magnification, thus allowing to meticulously identify apical anatomy and examine the resected root surface. EMS also demands the use of ultrasonic devices to perform root-end preparation. An additional feature of microsurgery is the absence or minimal bevel of the root respected surface, to decrease the amount of dentinal tubules exposed to microbial leakage.

Impact of Autologous Platelet Concentrates on Replanted Teeth
Autologous platelet concentrates (APCs) are produced by centrifuging the patient’s own blood and injecting or topically injecting the isolated plasma, which is rich in grown factors, regenerative cells and leukocytes, into the wound or defect. Although majority of the studies indicate that autologous platelet concentrates (APCs) may improve outcomes of tooth replantation, majority of the studies contained numerous sources of bias. Additionally, the sample size of the included subjects is inadequate to predict the clinical efficacy of APCs in management of replanted teeth. Large-scale, multi-center and long-term studies are required to ascertain the efficacy of APCs in improve the outcomes of tooth replantation.

Selective Antimicrobial Therapies for Periodontitis
Traditional antimicrobial therapies for periodontitis (PD) have long focused on non-selective and direct approaches that give  immediate though short lived clinical improvements. Professional cleaning of the subgingival biofilm by instrumentation of dental root surfaces, known as scaling and root planning (SRP), is the mainstay of periodontal therapy and is indisputably effective. Non-physical approaches, used as adjuncts to SRP, such as chemical and biological agents, will be the focus of this review. We will review traditional antibiotic and antiseptic approaches,  but will emphasize immunotherapeutic agents under development that indirectly inhibit microbial colonization/growth and/or bone loss by reducing inflammation. Moreover, those agents that have clear molecular targets and defined mechanisms of action will be stressed.   Many of these 'host modulation' agents,  have only become possible through decades of research on host-pathogen interactions and the immunopathogenesis of PD. More investment in such approaches is warranted and a goal worth pursuing given the tremendous benefits selective approaches might offer to patients with periodontitis.

Pulp Inflammation and Regeneration
The role of inflammatory mediators in dental pulp is unique. The local environment of pulp responds to any changes in the physiology that are highly fundamental, like odontoblast cell differentiation and other secretory activity.
