Electromyographic activity of the jaw muscles and mandibular kinematics in young adults with theoretically ideal dental occlusion: Reference values
2016
Background A necessary step to use neuromuscular analysis as diagnostic tool is to establish normal reference values for the physiological range in a healthy population. Surface electromyographic (sEMG) activity of the jaw muscles and mandibular kinematics were measured in young adults with theoretically ideal dental occlusion to determine normal reference values during different tasks. Differences between the sexes were evaluated. Material and Methods Forty young adults (20 men, 20 women; mean age 22.8 ± 3.9 years) with theoretically ideal dental occlusion were selected using very restrictive criteria. sEMG activity of the anterior temporalis (AT), posterior temporalis, masseter (MA), and …
Supportive periodontal therapy and periodontal biotype as prognostic factors in implants placed in patients with a history of periodontitis
2013
Objectives: To evaluate bone loss around implants placed in patients with a history of treated chronic periodontitis and who did or did not attend supportive periodontal therapy, after one year in function. Furthermore, the influence of periodontal biotype and level of plaque was also evaluated. Material and Methods: Forty-nine patients participated voluntarily in the study. All subjects had a history of chronic periodontitis, which had been previously treated. After the active treatment, 27 patients attended supportive periodontal therapy (SPT) and the rest did not (No SPT). The O’Leary plaque index and periodontal biotype were recorded for each subject and 246 Astra Tech® OsseospeedTM imp…
Occular complications following dental local anesthesia
2010
Objective: To determine the frequencyof appearance and the factors most commonlyassociated with ocular complications following dental local anesthesia, also establishing the location and type of anesthesia used. StudyDesign: An indexed search in the Pubmed and Compludoc databases was carried out with the keywords "oral anesthesia", "ocular", "ophthalmologic", "damage", "complications", "injection". We established a limitation that the literature had to have been published after the year 1970. A total of 19 articles were obtained, forming a total sample of 37 patients. The patient's sex, age, nerve anesthetized, type of anesthetic used, ophthalmological complication present, recoverytime, tr…
Radiofrequency treatment of cervicogenic headache
2010
Objectives: In the clinical management of facial pain, a possible cervical origin must be considered. A clinical exploration is therefore essential. The disorder originates in the intimate connections between the cranial portion of the spinal cord and the trigeminal system. Although solid evidence supporting the use of radiofrequency (RF) treatment is lacking, it remains one of the management options to be taken into account. The present study evalu - ates the efficacy of RF in application to cervicogenic headache. Study design: We present three cases of severe facial pain arising from different cervical structures. Results: In two cases the pain originated in cervical roots C2 and C3, whil…
Evaluation of the analgesic efficacies of Dexketoprofen Trometamol and Dexketoprofen Trometamol + Thiocolchicoside combinations in the impacted third…
2019
Background Postoperative pain is one of the most common complications. The aim of this study is to evaluate the analgesic efficacies of dexketoprofen trometamol and two different dosages of dexketoprofen trometamol + thiocolchicoside combination in the impacted third molar tooth operation. Material and Methods This randomized, double-blind study included 75 patients who did not have any disease. Patients were assigned to 3 groups. Group 1 received 25 mg dexketoprofen trometamol + 4 mg thiocholchicoside, Group 2 received 25 mg dexketoprofen trometamol +8 mg thiocholchicoside, and Group 3 received 25 mg dexketoprofen trometamol. In each group, the analgesic medication was administered twice a…
An evaluation of clinical, radiological and three-dimensional dental tomography findings in ectodermal dysplasia cases
2015
Background:This study aimed to review the results related to head and jaw disorders in cases of ectodermal dysplasia. The evaluation of ectodermal dysplasia cases was made by clincal examination and examination of the jaw and facial areas radiologically and on cone-beam 3-dimensional dental tomography (CBCT) images. Material and Methods: In the 36 cases evaluated in the study, typical clinical findings of pure hypohidrotic ectodermal displasia (HED) were seen, such as missing teeth, dry skin, hair and nail disorders. CBCT images were obtained from 12 of the 36 cases, aged 1.5- 45 years, and orthodontic analyses were made on these images. Results: The clinical and radiological evaluations de…
Fixed dental prostheses with vertical tooth preparations without finish lines: A report of two patients
2016
Tooth abutments can be prepared to receive fixed dental prostheses with different types of finish lines. The literature reports different complications arising from tooth preparation techniques, including gingival recession. Vertical preparation without a finish line is a technique whereby the abutments are prepared by introducing a diamond rotary instrument into the sulcus to eliminate the cementoenamel junction and to create a new prosthetic cementoenamel junction determined by the prosthetic margin. This article describes 2 patients whose dental abutments were prepared to receive ceramic restorations using vertical preparation without a finish line.
Histopathological characterization of the oral lichenoid disease subtypes and the relation with the clinical data
2016
Background: The aim of the study was to analyze the histopathological characteristics of samples with a diagnosis of oral lichenoid disease (OLD) and their link with the location and the type of clinical lesion, and the clinicopathological subtypes.
Stromal myofibroblasts in oral leukoplakia and oral squamous cell carcinoma
2011
Objectives: Oral leukoplakia (OL) is the main potentially malignant disorder and oral squamous cell carcinoma (OSCC) is the most common malignancy of the oral mucosa. Stromal myofibroblasts play an important role in tumor invasion and metastasis, due to its ability to modify the extracellular matrix. This study aimed to evaluate the presence of stromal myofibroblasts in OL and OSCC. Differences in the presence of myofibroblasts among OL with distinct grades of epithelial dysplasia as well as between histologically high- and low-invasive OSCC were also assessed. Study Design: A total of 30 OL and 41 OSCC from archival formalin-fixed, paraffin-embedded specimens were evaluated. 10 samples of …
Effect of posterior gingival smile on the perception of smile esthetics
2013
Objectives: To evaluate and compare the influence of posterior gummy smile on the perception of smile esthetics by orthodontists, general-dentists and laypersons. Study Design: A frontal photograph of a smile with normal gum exposure was chosen and manipulated digitally using Adobe Photoshop C3 to generate three further images with posterior gum exposure of 4, 6 and 8mm. These four images were assessed by the three evaluator groups: orthodontists (n=40), general-dentists (n=40) and laypersons (n=40). Both orthodontists and dentists had at least ten years professional experience and laypersons were aged between 40-50 years. The proportion of men to women was 20:20 in each group. Evaluators a…
