The goal of this preclinical study was to substantiate the effectiveness of using autologous platelet-rich plasma (PRP) to heal erosive lesions in the oral cavity. This study employed analyses of qualitative and semiquantitative morphologic parameters, including histologic assessment of biopsy specimens. The most favorable results were observed in a group of 16 dogs receiving 2-mL injections of autologous PRP 3 times: day 1 of the experiment and after 7 and 14 days of observation; in this group, no traces of inflammatory symptoms were found at the end of the observation period (14 days)...

The loss of interdental papillae may create esthetic and phonetic problems and facilitates food impaction. Nonsurgical and surgical approaches can be developed to restore these areas, depending on the amount of tissue lost. Periodontal surgical techniques are difficult to perform in the interdental space because of the limited amount of tissue and poor blood supply. The aim of this article is to describe a periodontal plastic surgical technique in which subepithelial connective tissue grafts associated with composite restorations are used to reconstruct interdental papillae...

Tooth avulsion in children and adolescents demands emergency treatment to increase the chances of successful reimplantation. The treatment prognosis depends on intrinsic and extrinsic factors, such as the extra-alveolar time until reimplantation, storage medium, handling, and periodontal ligament condition of the avulsed tooth as well as the patient's general health. This case report describes the treatment of an 11-year-old boy who suffered an avulsion of the maxillary right central incisor followed by delayed reimplantation after the tooth was stored in a dry medium for 6 days...

The dental profession is still pursuing the most effective way to treat white-spot lesions in order to produce a sound and esthetically pleasing enamel surface. The aim of the present research was to evaluate in vitro the effects of a dentifrice with nanohydroxyapatite (nano-HAp) on the roughness, color, lightness, and brightness (gloss) of bovine enamel subjected to pH cycling. Twelve enamel discs prepared from bovine incisors were divided into 2 experimental groups: dentifrice with sodium fluoride (Colgate Total 12 Clean Mint) and dentifrice with nanoHAp (Megasonex)...

Dentinogenesis imperfecta type 2 (DI-2), also known as hereditary opalescent dentin, is a rare, genetically linked condition that affects both primary and permanent teeth. Severe attrition requiring full-mouth rehabilitation is a common finding associated with DI-2. Dental rehabilitation options include a variety of invasive and noninvasive restorative techniques dictated by the age of the patient. Growth and development must be considered and may result in a restorative challenge for the dental practitioner, particularly when the patient in question is a child...

The etiology of degenerative processes of the temporomandibular joint (TMJ) remains unclear, as they could be the result of trauma, infection, or autoimmune disease. Improving the diagnosis of autoimmune disease, whether the TMJ is the primary site or secondarily affected by a systemic disease, is of fundamental importance in selecting treatment that will address the causes rather than just relieve the symptoms. The purposes of this article are to discuss autoimmunity as an etiologic factor in degenerative processes of the TMJ by presenting clinical cases and to highlight the importance of imaging and serologic examinations for diagnosis...

This in vitro study evaluated the marginal microleakage of composite inlays luted with 3 different cement systems. The null hypothesis was that the luting materials would not influence dye penetration, showing the same degree of microleakage. Thirty-six sound molars were selected, mesio-occlusodistal cavities were prepared, and the teeth were randomly divided into 3 groups (n = 12). Composite resin inlay restorations were made and cemented using a dual-curing resin cement (Calibra), a light-curing flowable composite (Charisma Flow), or a self-adhesive resin cement (RelyX Unicem)...

Permanent maxillary central incisor impaction is a rare condition of multifactorial etiology that should be treated on diagnosis. This article describes multidisciplinary treatment of an 11-year-old patient presenting with a permanent maxillary right central incisor that was impacted due to the presence of 2 supernumerary teeth. The diagnosis was reached through clinical evaluation, radiography, and cone beam computed tomography. Treatment involved the surgical removal of the supernumerary teeth followed by traction of the impacted tooth through a combination of removable and fixed orthodontic appliances...

Implant overdentures are considered a standard treatment option by many practitioners, especially for edentulous mandibles. Stud attachments have been used extensively in the construction of these overdentures. In this study, the retentive forces of O-ring/ball and Locator overdenture attachments under various conditions in the mouth were investigated through pull-out tests. In dry testing, the retentive forces of the O-ring/ball attachment started higher than those of the Locator attachment but significantly decreased after 50 insertion-removal cycles (P = 0...

The objective of this study was to determine the diagnostic accuracy of panoramic radiography and magnetic resonance imaging (MRI) for detection of signs of temporomandibular joint (TMJ) degenerative joint disease (DJD). Panoramic radiography and bilateral MRI and computed tomography (CT) of the TMJs were performed for 705 subjects. Three calibrated board-certified radiologists who were blinded to the clinical findings interpreted all images. The diagnoses of DJD established using the panoramic radiographs and MRIs were compared to the reference standard diagnoses derived from the CTs...

The purpose of this study was to evaluate the fracture resistance of teeth with standard or extended mesio-occlusodistal (MOD) preparations after restoration with bonded computer-aided design/computer-aided manufacturing (CAD/CAM) materials. Standard or extended MOD cavities were prepared in 60 of 70 extracted, caries-free third molars. In the standard MOD preparations (n = 30), 4.5- mm buccal and lingual/palatal wall thickness remained, and proximal boxes extended 1.0 mm coronal to the cementoenamel junction...

The primary purpose of this study was to evaluate the prevalence of inferior alveolar nerve (IAN) bifurcations through the utilization of cone beam computed tomography (CBCT). The secondary purposes of this study were to analyze the average distance from the main trunk to its branch at the greatest point, to calculate the average distance of the bifid IAN from the apices of the teeth, and to determine the appropriate classification for each IAN bifid nerve according to the types described by Nortjé et al: type 1, 2 canals originating from a single foramen with a narrower inferior canal; type 2, 2 canals originating from a single foramen with a superior canal extending to the second or third molar; type 3, 2 canals of equal size that arise from 2 mental foramina that may link into a single canal near the molars...

Within the last few decades, an increasing number of adults have sought orthodontic therapy. One disadvantage of pursuing orthodontic treatment in adulthood is the lengthened time span required to complete tooth movement. The purpose of this article is to review the biologic mechanisms of accelerated tooth movement as well as the literature on nonsurgical and surgical techniques that may reduce the duration of orthodontic treatment.
