Computer-aided design methods combined with computer-aided manufacturing assist in more accurate and fast removal of nonosteolytic intraosseous pathologies, which are often clinically indistinguishable from adjacent healthy bone tissue. Among these pathologies, idiopathic osteosclerosis is an area of focal radiopacity that cannot be attributed to inflammatory, dysplastic, neoplastic, or systemic disorders. We present here the case of a 54-year-old female patient seeking implant-supported rehabilitation with no other complaints. Computed tomography scan suggested a hyperdense intraosseous lesion in the left mandible. The surgical guide, designed with the add-on OrtogOnBlender, was used to design the bone window through which the osteosclerotic area was approached, preserving bone tissue and reducing operative time. The surgical cavity was filled according to the principles of guided bone regeneration. The patient is awaiting osseointegration of the bone substitute to continue with her surgical-prosthetic treatment. [ABSTRACT FROM AUTHOR]

The aim of this study is to present a systematic review of the effectiveness of discopexy in managing internal derangement of the temporomandibular joint (TMJ). We searched MEDLINE through PubMed, SCOPUS, Web of Science, Cochrane Central Register of Controlled Trials (CENTRAL), and grey literature accessed through Google Scholar, Openthesis, and hand-searching from inception to July 2020. The search yielded 363 potentially relevant studies. After screening titles and abstracts, 41 full-text articles were assessed for eligibility and 7 studies were included in the meta-analysis. There was an overall decrease in visual analog scale (VAS) pain score of 4.59 cm (95% CI 95% 2.03 to 7.16; P <.001) during follow-up and an overall increase of 10 mm (95% CI 6.93 to 13.01; P <.001) in mouth opening after TMJ surgeries with discopexy. The available evidence showed an overall decrease in VAS pain score and an improvement in mouth opening after TMJ surgeries with discopexy. Changes in maximal interincisal opening were greater after arthroscopic disc repositioning compared to open-joint procedures. [ABSTRACT FROM AUTHOR]

Cone beam computed tomography is widely used in dentistry because of its easy accessibility, low cost, and better accuracy compared to medical tomography. Objectives: The present study aims to conduct a systematic review of the literature on evaluation of the jaw using cone beam computed tomography. Study Design: A bibliographic search was performed in the electronic databases PubMed, Scopus, Embase, and Web of Science. Results: At the end of the analysis, 10 articles published between 1998 and 2015 were included. Conclusions: Cone beam computed tomography is a precise and fast method, used to evaluate digital images in high resolution, with sharpness and precision. In addition, the acquisition of these images is essential to measure bone elements, in both quantity and quality. It should also be noted that the forecast of bone strength will depend on several factors, such as bone density and microarchitecture. Thus, the professional is less likely to make mistakes that interfere with the prognosis of dental treatment. [ABSTRACT FROM AUTHOR]

Unicystic ameloblastoma is a benign epithelial odontogenic neoplasm that represents about 5% to 15% of all intraosseous ameloblastomas, and its biological behavior is related to its histopathologic subtypes, with the mural variant being the most aggressive. The aim was to evaluate the effectiveness of conservative and radical surgical approaches in the treatment of unicystic ameloblastomas. A systematic literature review was performed using the Science Direct, Embase, Cochrane Collaboration Library, and PubMed/MEDLINE databases. Studies related to conservative and radical surgical therapies for the treatment of unicystic ameloblastomas were selected. Seven hundred ninety-one studies were found. After screening the titles and abstracts, 25 studies were considered eligible and read by the evaluators. After the analysis, 5 articles met all inclusion criteria and were included in this review. Studies have shown that a conservative surgical approach for the treatment of unicystic ameloblastoma is recommended only for the luminal and intraluminal variants and is not recommended for the mural subtype. However, to carry out a radical treatment, one must consider the age and health of the patient. Postsurgical clinical and radiographic monitoring is of fundamental importance for early detection of recurrence. [ABSTRACT FROM AUTHOR]

The present study aims to carry out a bibliographic review regarding oral changes resulting from electronic cigarette smoking. The PubMed database was researched with the following uniterms and Boolean operators: "electronic cigarette" OR "e-cigarette" OR "electronic cigarettes" AND "oral health" from January 2015 to January 2020. Additionally, books and epidemiologic data were used. The inclusion criteria included articles published in Portuguese and/or English that met the theme proposed by the study. Nonsystematic literature reviews and articles that did not strictly refer to electronic cigarettes were excluded. The final sample consisted of 14 articles, of which 7.14% were classified as a systematic review (n = 1), 78.57% as in vivo studies (n = 11), 7.14% as a case control study (n = 1), and 7.14% as a pilot study (n = 1). There was a low level of published evidence on the results of oral health. The effects mentioned suggested periodontal changes and cellular damage in oral tissues. In addition, electronic cigarette smoking has not demonstrated full health security. [ABSTRACT FROM AUTHOR]

The dentist must be informed about the development of oral bisphosphonates complications and what clinical course to follow according to the individual treatment. This study aims to evaluate the knowledge and conduct of dentists about bisphosphonates and their effects on the oral cavity. The sample consisted of 60 dentists specialized in surgery (n = 20), implantology (n = 20), and periodontics (n = 20) who answered a structured questionnaire validated by Albuquerque (2014) with 12 questions on personal subjects, anamnesis, and knowledge on bisphosphonates such as their indications, adverse effects, and treatments. A total of 60 dentists were interviewed; 88.3% have seen patients who report the use of bisphosphonates, and 33.3% have previously knowledge of its oral complications. A considerable number of dentists were aware of the existence of bisphosphonates and only a small sample knew about their complications and treatment modalities. [ABSTRACT FROM AUTHOR]
