PURPOSE: This study investigated the local anesthetic efficiency of tramadol versus lidocaine hydrochloride in maxillary infiltration anesthesia. MATERIALS AND METHODS: This study was a randomized double-blinded study involving 50 healthy volunteers. In the experimental part of this study, each volunteer received 1 buccal 0.5-mL injection of tramadol hydrochloride 25 mg on one side and 1 buccal 0.5-mL injection of vasoconstrictor-free lidocaine hydrochloride 20 mg on the other side...

BACKGROUND: Current treatment of equine PPID requires daily oral medication, which is expensive and difficult from a management perspective. A minimally invasive surgical palliation of this chronic condition is appealing because it is envisioned to be a single treatment which, while not curative, will alleviate the clinical signs of disease dramatically thereby improving the welfare of the horse. OBJECTIVE: To develop a surgical approach to the equine pituitary gland, for subsequent treatment of pituitary pars intermedia dysfunction...

Background: Crown fracture is the most common type of fracture and frequently affects the anterior teeth. Crown fractures have been treated in several ways depending on the location and kind of fracture. This case emphasizes reattachment of fractured fragments using fiber-reinforced post. Also this case report underlines the related aesthetic concerns of reattaching of the fractured fragment. Case Report: Intraorally, examination revealed a complicated crown-root fracture of the left maxillary central (#21) and lateral incisor (#22)...

BACKGROUND: Different surgical procedures have been proposed to achieve horizontal ridge reconstruction of the anterior maxilla; all these procedures, however, require bone replacement materials to be adapted to the bone defect at the time of implantation, resulting in complex and time-consuming procedures. The purpose of this study was to describe how to use a 3D printed hardcopy model of the maxilla to prepare customized milled bone blocks, to be adapted on the bone defect areas using a minimally invasive subperiosteal tunneling technique...

OBJECTIVE: A commercially available mouth rinse with ethyl lauroyl arginate and essential oils claims to have better antimicrobial properties than the traditional essential oil products. The aim of this study was to compare the plaque and gingivitis inhibiting effect of the commercial product containing essential oils with ethyl lauroyl arginate with one placebo and one negative control in a modified experimental gingivitis model. MATERIALS AND METHODS: In three groups of healthy volunteers, experimental gingivitis was induced and monitored over 21 d, simultaneously treated with the commercial test solution, 21...

The impact of high-refined carbohydrate (HC) diet on fat accumulation, adipokines secretion and systemic inflammation is well described. However, it remains unclear whether these processes affect bone remodeling. OBJECTIVE: To investigate the effects of HC diet in the alveolar bone and femur parameters. METHODS: BalbC mice were fed with conventional chow or HC diet for 12 weeks. After experimental time maxillae, femur, blood and white adipose tissue samples were collected...

Potassium channel tetramerization domain containing 15 (Kctd15) was previously found to have a role in early neural crest (NC) patterning, specifically delimiting the region where NC markers are expressed via repression of transcription factor AP-2a and inhibition of Wnt signaling. We used transcription activator-like effector nucleases (TALENs) to generate null mutations in zebrafish kctd15a and kctd15b paralogs to study the in vivo role of Kctd15. We found that while deletions producing frame-shift mutations in each paralog showed no apparent phenotype, kctd15a/b double mutant zebrafish are smaller in size and show several phenotypes including some affecting the NC, such as expansion of the early NC domain, increased pigmentation, and craniofacial defects...

The aim of this study was to evaluate the bacterial reduction promoted by ProTaper Next and Twisted File by comparing to ProTaper Universal and manual technique. Sixty distobuccal root canals of maxillary molars sterilized with ethylene oxide were contaminated with Enterococcus faecalis broth culture. After incubation for 21 days, bacterial samples were collected and cultured on m-Enterococcus agar plates. The root canals were divided into 4 groups, according to the system used for instrumentation: ProTaper Next, Twisted File, ProTaper Universal, and crown down manual technique...

The aim of this study was to determine oxygen saturation levels in the dental pulp of maxillary premolars in different age groups. A total of 120 human maxillary premolars with normal dental pulps were selected covering the following age groups: 20-24, 25-29, 30-34, 35-39 and 40-44 years (n=24 each group). Oxygen saturation was assessed using pulse oximetry. Analysis of variance was used to assess differences in oxygen saturation levels and Tukey's test was used to identify the age groups that differed from each other...

Cleft lip and palate patient represent a challenging experience for the surgeon. This kind of patients had to be followed by a multidisciplinary team from the beginning to the end to avoid the deformation sequelae. During the several surgical procedures, the bone graft represents a possible procedure that, through the new procedure, could be avoided. Unfortunately, patient treated following the previous procedure must be submitted to alveolar bone graft to coordinate the arch, to restore the maxillary integrity, to allow the correct dentition...

Adenomatoid odontogenic tumor (AOT), a benign (hamartomatous) lesion of odontogenic origin, is an uncommon tumor which affects mainly females in the second decade. This lesion is most commonly associated with an impacted maxillary canine. This paper reported a case of AOT, in a 16-year-old female, associated with an impacted maxillary left lateral incisor. The evolution of this tumor was followed over 36 months and 24 months after excision.

This study evaluated the stress distribution in endodontically treated teeth, weakened (W) or not weakened (NW), restored with different materials of prosthetic crown using 3D-FEA. Models of a maxillary canine were constructed based on micro-CT images and divided into the groups: G1 (control) - sound tooth; G2 to G7 - endodontically treated teeth restored with glass fiber post (GFP); which G2 to G4 simulated NW root and G5 to G7 simulated W root. For crown material the teeth were restored with: G2 and G5: metallic coping and ceramic veneering, G3 and G6: zirconia coping and ceramic veneering, G4 and G7: alumina coping and ceramic veneering...

This study determined the oxygen saturation (SaO2) in dental pulp of healthy maxillary and mandibular molars. Mean of SaO2 was evaluated in 112 maxillary and mandibular molars using pulse oximetry. Quantitative variables were described by mean and standard deviation. Variables with symmetric distribution were compared by Student t test and Mann-Whitney test. Pearson's correlation coefficient was used to correlate quantitative variables. Analysis of variance was used to assess differences in SaO2 levels between the molar groups, followed by post-hoc Tukey...

Malignancies of the nasal cavity and paranasal sinuses account for 1% of all malignancies and 3% of malignancies of the upper aerodigestive tract. In the sinonasal tract, nearly half of all malignancies arise in the nasal cavity, whereas most of the remaining malignancies arise in the maxillary or ethmoid sinus. Squamous cell carcinoma is the most common histological subtype of malignant tumors occurring in this area, followed by other epithelial carcinomas, lymphomas, and malignant soft tissue tumors. Although many of these tumors present with nonspecific symptoms, each tumor exhibits characteristic imaging features...
