Use of Marsupialization as a Definitive Treatment for Large-sized Dentigerous Cysts in a Patient with Mucopolysaccharidosis Type I.

The correct diagnosis is fundamental for the appropriate treatment to be employed in a particular pathology. The best treatment is not the one that solves only local problems, fragmenting the patient, and therefore, it is necessary to integrate the entire systemic condition of the individual before initiating any local treatment. This context inevitably requires dentistry to participate in a multidisciplinary approach, where the role of the dentist is expanded in concepts that encompass ethics, human dignity, and professional valorization.

Photobiomodulation Therapy Improves Postoperative Pain and Edema in Third Molar Surgeries: A Randomized, Comparative, Double-Blind, and Prospective Clinical Trial.

Purpose: Laser light has biological effects that can modulate inflammatory processes. Thus, this study aimed to evaluate the effects of photobiomodulation (PBM) therapy on pain, edema, and trismus after the extraction of retained third molars.

Methods: A split-mouth, double-blind, randomized clinical trial (RCT) was conducted in 13 patients with similar bilateral third molars who received intraoral application PBM therapy at 4 points with a diode laser at 810 nm wavelength, 6 J (100 mW, 60 seconds/point) on 1 side (the PBM side); and laser irradiation simulation on the other side (SHAM side).

The effectiveness of hydroxyapatite-beta tricalcium phosphate incorporated into stem cells from human exfoliated deciduous teeth for reconstruction of rat calvarial bone defects.

Objective: To investigate the effects of stem cells from the pulp of human exfoliated deciduous teeth (SHED) on biphasic calcium phosphate granules (BCP) to repair rat calvarial defects as compared to autogenous bone grafting.

Materials And Methods: A defect with a 6-mm diameter was produced on the calvaria of 50 rats. BCP granules were incorporated into SHED cultures grown for 7 days in conventional (CM) or osteogenic (OM) culture media.

Improvement of bone repair with l-PRF and bovine bone in calvaria of rats. histometric and immunohistochemical study.

Objectives: The effect of leucocyte- and platelet-rich fibrin (L-PRF), associated with DBBM (deproteinized bovine bone mineral; Bio-Oss®) was investigated and compared with autogenous bone graft as a standard material for filling bone defects.

Material And Methods: A defect of 5 mm in diameter was performed in 40 calvaria of rats. The animals were divided into 5 groups and received blood clot (CO), autogenous bone (AUT), DBBM (BIO), L-PRF, or DBBM associated with L-PRF (BIO-LPRF).

Doxycycline and Autogenous Bone in Repair of Critical-Size Defects.

Purpose: The association of doxycycline (DOX) and autogenous bone on repair of critical-size defects was evaluated.

Materials And Methods: Fifty albino rats were divided into 5 groups (n = 10). A 5-mm diameter defect was treated with: control (CO)-blood clot; DOX in Natrosol (NAT)-10% gel; NAT-gel; particulate autogenous bone (PAB); and PAB + DOX - PAB associated with 10% DOX gel.

Open Reduction in Pediatric Condylar Fracture.

Facial fractures in children are rare. Lack of pneumatization, fat pockets, mixed dentition, contribute to the elasticity and bone stability. When mandibular fractures occur in children, most often involve the condyle by indirect trauma.

Effect of topical application of chlorhexidine and metronidazole on the tissue repair of palatal wounds of rats: a clinical and histomorphometric study.

Objective: This study investigated the effect of topical application of 2% chlorhexidine (GCl) and metronidazole (Gme) pastes for the repair of palatal wounds in rats.

Study Design: A 4-mm diameter wound was created on the palates of 27 rats separated randomly into 3 groups of 9 animals each, according to the treatment received: GNa (Control: natrosol), GCl, and GMe. The animals were euthanized after 3, 6, and 10 days, and wound closure was clinically and histomorphometrically assessed.

Tissue engineering: using collagen type I matrix for bone healing of bone defects.

Among the many tissues in the human body, bone has been considered as a powerful marker for regeneration and its formation serves as a prototype model for tissue engineering based on morphogenesis. Therefore, collagen type I is one of the most useful biomaterials used in tissue engineering as extracellular matrix components capable to promote bone healing. The literature reveals excellent biocompatibility and safety due to its biological characteristics, such as biodegradability and weak antigenicity, making collagen type I the primary resource in medical applications.

Anterior pericranial flap for frontal sinus duct obliteration: is it a valuable resource?

Inappropriate treatments of frontal sinus fractures may lead to serious complications, such as mucopyocele, meningitis, and brain abscess. Assessment of nasofrontal duct injury is crucial, and nasofrontal duct injury requires sinus obliteration, which is often accomplished by autogenous grafts such as fat, muscle, or bone. These avascular grafts have an increased risk of resorption and infection and donor site morbidity.

Comparative radiographic evaluation of alveolar bone healing associated with autologous platelet-rich plasma after impacted mandibular third molar surgery.

Purpose: This study radiographically evaluated the performance of autologous platelet-rich plasma (PRP) applied in tooth sockets.

Patients And Methods: Thirty extractions of bilateral impacted mandibular third molars were performed in 15 volunteers (7 men, 8 women; 18 to 22 years old). After extraction of right and left mandibular third molars, the socket at 1 side received the autologous PRP (PRP group) and the other was filled with blood clot (control group).

Deep impacted mandibular second molar: a case report.

Impaction of mandibular second molars is relatively rare. A case of a deep impacted mandibular right permanent second molar in a 26-year-old woman is presented. This article describes the extraction of the tooth and reports the risks of the surgical procedure.

Comparative study of rules employed for calculation of pediatric drug dosage.

The present study was conducted to evaluate the utilization of Clark's, Salisbury and Penna's rules and the Body Surface Area (BSA) formula for calculation of pediatric drug dosage, as well as their reliability and viability in the clinical use. These rules are frequently cited in the literature, but much controversy still exists with regards to their use. The pediatric drug dosage was calculated by utilization of the aforementioned rules and using the drugs Paracetamol, Dipyrone, Diclofenac Potassium, Nimesulide, Amoxicillin and Erythromycin, widely employed in Pediatric Dentistry.
