Clinical and Microbiologic Outcomes of Ceramic Laminate Veneers Bonded to Teeth Without a Finish Line: 1-year Results of a Prospective Study.

To evaluate changes in the periodontium of teeth restored with ultrathin (0.2 to 0.39 mm) ceramic laminate veneers (CLVs) placed subgingivally without a finish line compared to the same teeth before restorative treatment and to nonrestored antagonist teeth in healthy periodontium patients.

Evaluation of Vitamin D isolated or Associated with Teriparatide in Peri-Implant Bone Repair in Tibia of Orchiectomized Rats.

(1) Background: The objective of this study was to evaluate the morphometry of peri-implant bone tissue in orchiectomized rats, treated with vitamin D isolated or associated with teriparatide. (2) Methods: 24 rats were divided into 4 groups: ORQ-orchiectomy, without drug treatment, ORQ+D-orchiectomy, treated with vitamin D, ORQTERI-orchiectomy, treated with teriparatide and ORQTERI+D-orchiectomy, treated with teriparatide + vitamin D. Each animal received an implant in the tibial metaphysis.

Efficacy of two polishing systems in reestablishing the surface smoothness of posterior monolithic lithium disilicate restorations: One-year results of a split-mouth randomized controlled clinical trial.

Statement Of Problem: Selecting the optimal polishing procedure to reestablish surface smoothness after occlusal adjustment is essential for the long-term success of glass-ceramic restorations. While in vitro studies have shown different effective polishing protocols, clinical trials are lacking.

Purpose: The purpose of this split-mouth controlled clinical trial was to evaluate the effectiveness of 2 polishing systems in reestablishing the surface smoothness of posterior monolithic lithium disilicate ceramic restorations.

Teriparatide improves alveolar bone modelling after tooth extraction in orchiectomized rats.

Objective: The aim of this study was to evaluate bone metabolism in the alveolar repair process in orchiectomized male rats treated with teriparatide.

Materials And Methods: A total of 78 rats were divided into three groups: 26 oriectomized rats treated with teriparatide (ORQTRAT), 26 untreated orchiectomized rats (ORQ), and 26 rats which had undergone sham surgical procedures (SHAM), all these animals underwent extraction of the central incisor tooth. Thus, a histological analysis was performed (42 days).

Evaluation of the Different Biomaterials Used in Alveolar Cleft Defects in Children.

The aim of this study was to use a literature review to evaluate and compare the different biomaterials used in surgeries for the closure of the palatal and alveolar clefts as alternatives to isolated autografting. For the search strategy, the PubMed and Medline databases were used with the indexing terms "'cleft palate' (Mesh), 'biocompatible materials' (Mesh), and 'dentistry' (Mesh)." There was no restriction on language or publication time.

Effect of intermittent teriparatide (PTH 1-34) on the alveolar healing process in orchiectomized rats.

Objective: To evaluate intermittent teriparatide therapy's influence on the alveolar healing process in rats with induced osteoporosis.

Materials And Methods: Fifty-four male rats were divided into three groups: fictitious surgery (SHAM), bilateral orchiectomy (ORQ NT), and bilateral orchiectomy treated with teriparatide (ORQ TERI). Right upper incisor extraction was performed.

Short term sodium alendronate administration improves the peri-implant bone quality in osteoporotic animals.

Objective: The aim of this study was to evaluate the bone repair process at the bone/implant interface of osteoporotic rats treated with sodium alendronate through the analysis of microtomography, real time polymerase chain reactions and immunohistochemistry (RUNX2 protein, bone sialoprotein (BSP), alkaline phosphatase, osteopontin and osteocalcin).

Material And Methods: A total of 42 rats were used and divided in to the following experimental groups: CTL: control group (rats submitted to fictitious surgery and fed with a balanced diet), OST: osteoporosis group (rats submitted to a bilateral ovariectomy and fed with a low calcium diet) and ALE: alendronate group (rats submitted to a bilateral ovariectomy, fed with a low calcium diet and treated with sodium alendronate). A surface treated implant was installed in both tibial metaphyses of each rat.

Large Dentigerous Cyst Associated to Maxillary Canine.

Dentigerous cysts are defined as a cyst originated by separation of the follicle of dental crown of a tooth unerupted. Although most dentigerous cysts are considered developmental cysts, some cases seem to have an inflammatory origin. The aim of this study was to show a case of an 8-year-old patient, male, presenting a lesion in maxilla with large proportions.

Conservative Management of Central Cemento-Ossifying Fibroma.

Central cemento-ossifying fibroma is characterized by the combined production of osteoid and cementoid tissue. Radiographically, this lesion is presented as an outlined cortical and variable radiopaque spots, also can be present complete radiolucent or different degrees of radiopacity. The recommended treatment is curettage or enucleation, and the recurrence rate is less than 5%.

The Importance of Correct Diagnosis of Crocodile Tears Syndrome.

The excessive unilateral tearing as a result of gustatory stimuli is a characteristic of crocodile tears syndromes. The aim of this study is to report 2 cases of Frey and crocodile tears syndromes, considering diagnosis, monitoring, and selection of appropriate treatment. A 74-year-old female patient presented with a history of Bell palsy, tearing on left eye at the moment of chewing, and absence of pain.

Scientific evidence on the use of recombinant human bone morphogenetic protein-2 (rhBMP-2) in oral and maxillofacial surgery.

Purpose: This study aimed to identify the main indications for the use of recombinant human bone morphogenetic protein-2 (rhBMP-2) for bone repair and maintenance in the maxilla and mandible through a review of clinical trials evaluating the viability of using rhBMP-2 to delay the installation of dental implants, thus allowing satisfactory bone formation and long-term osseointegration.

Methods: Literature search of the PubMed/Medline databases was performed using the following MeSH index terms-"bone morphogenetic protein 2" and "dentistry". Only clinical trials necessarily published in English, related to dentistry, and focused on bone reconstruction in critical defects, post-extraction alveoli, increasing the atrophic alveolar ridge, or surgery for maxillary sinus elevation were included, regardless of the age, sex, ethnicity, associated morbidities, or period of publication.
