Automation in Dentistry with Mechanical Drills and Lasers for Implant Osteotomy: A Narrative-Scoping Review.

The popularity of implants is increasing with the aging population requiring oral-dental rehabilitation. There are several critical steps in the implant workflow, including case selection, implant design, surgical procedure, biological tissue responses, and functional restoration. Among these steps, surgical osteotomy procedures are a crucial determinant of clinical success. This brief review was aimed at outlining the current state of the field in automation-assisted implant surgical osteotomy technologies. A broad search of the literature was performed to identify current literature. The results are outlined in three broad categories: semi-automated static (image-guided) or dynamic (navigation-assisted) systems, and fully-automated robotic systems. As well as the current mechanical rotary approaches, the literature supporting the use of lasers in further refinement of these approaches is reviewed. The advantages and limitations of adopting autonomous technologies in practical clinical dental practices are discussed. In summary, advances in clinical technologies enable improved precision and efficacious clinical outcomes with implant dentistry. Hard-tissue lasers offer further advancements in precision, improved biological responses, and favorable clinical outcomes that require further investigation.

Photobiomodulation Therapy for Wound Care: A Potent, Noninvasive, Photoceutical Approach.

GENERAL PURPOSE: To provide background and examine evidence for the therapeutic application of light energy treatments for wound healing. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After completing this continuing education activity, you should be better able to:1. Explain the basics of lasers, light-emitting diodes, and light-tissue interactions as they apply to photobiomodulation therapy.2. Summarize the results of the authors' literature review of the evidence regarding the therapeutic applications of photobiomodulation treatments for wound healing. ABSTRACT: To provide background and examine evidence for the therapeutic applications of light energy treatments for wound healing.A search was performed in PubMed for peer-reviewed scientific articles published in the last 5 years using the search terms "photobiomodulation therapy" and "low-level laser therapy," and these terms combined with "wound," using a "human species" filter. This search yielded 218 articles on photobiomodulation therapy or low-level laser therapy and wounds. Of these, only articles on in vivo wound care using light treatments were specifically included in this review (n = 11).The wound healing effects of low-dose laser treatments were first described over 50 years ago. Various doses ranging from 0.1 to 10 J/cm and wavelengths ranging from 405 to 1,000 nm appear to provide therapeutic benefits for a broad range of chronic wounds. A range of light energy sources from LEDs to lasers have been used and have specific advantages and limitations. There is a lack of consensus on standardized treatment parameters such as wavelengths, dose, and therapeutic outcomes in the reviewed studies, preventing direct comparison and clinical protocol recommendation. An expert opinion based on ongoing research studies and reported literature is offered.Noninvasive, economical, and multipurpose light devices are an attractive tool for wound management. However, there is an urgent need in the wound care community to develop optimal clinical protocols for use based on well-designed, rigorous clinical research studies.

Keratocyst: a case report with characterization by CT / Queratocisto: relato de um caso com caracterização pela TC

The odontogenic keratocyst, or OKC is the third most common odontogenic cyst categorized by the WorldHealth Organization classification. It?s a developmental, no inflammatory odontogenic cyst that arises from cell rests of dental lamina, although it has a difference in its mechanism of growth that gives a different radiographic appearance. OKCs have a high recurrence rate and develop more aggressively than any other jaw cysts. Patients in their second and third decades of life are affected most commonly. We present a 21-years-old female that an OKC affected in hera left mandible in huge ratio

O Queratocisto Odontogênico ou QTO é o terceiro mais comum cisto odontogênico classificado pela Organização Mundial de Saúde. É um cisto odontogênico, não inflamatório, de desenvolvimento resultante de restos celulares da lâmina dentária, embora tenha uma diferença em seu mecanismo de crescimento, o que da uma diferente aparência radiográfica. Os QTOs tem uma alta taxa de recidiva e desenvolve uma forma mais agressiva do que qualquer outro cisto da mandíbula. Pacientes da segunda e terceira década devida são os mais afetados. Nós apresentaremos um caso com um paciente de 21 anos de idade da qual o QTO afeta a mandíbula esquerda em uma dimensão enorme

Cystic hygroma: characterization by computerized tomography.

Lymphangiomas are benign nonencapsulated lesions composed of sequestered noncommunicating lymphoid tissue lined by lymphatic endothelium and are thought to be caused by congenital obstruction of lymphatic drainage. They are subclassified by vessel size, such as the capillary, which is rare and located in subcutaneous tissue, cavernous (located about the mouth and tongue), and cystic (cystic hygromas). The cystic hygromas show a predilection for the neck (75%) and maxilla (20%), and the remaining 5% arise in rare locations such as the mediastinum, retroperitoneum, bone, kidney, colon, liver, spleen and scrotum. Only 3%-10% of neck lesions extend into the mediastinum. In this paper, we report a rare case of cystic hygroma with a huge dimension discussing the use of computed tomography scanning for diagnosis.

Estudo radigrafico da ATM por meio do indice craniomandibular em pacientes parcialmente edentados - Parte II / Radiographic study of T.M.J. through the Craniomandibular index in partially edentulous patients - Part II

O objetivo desta pesquisa foi de avaliar a AT.M. por meio da radiografia panorâmica modificada, usando o Índice Craniomandibular, proposto por FRICTON e SCHIFFMAN6 (1986) e modificado por GlI}-1O (1995, 1996) em pacientes com algum tipo de sinal ou sintoma de desordem craniomandibular (D.e.M.), parcialmente edentados, portadores e não portadores de prótese parcial removível e/ou prótese total. Na avaliação radiográfica foi utilizada a radiografia panorâmica modificada para A T. M., que se trata de um recurso especial que alguns aparelhos panorâmicos apresentam. Foram mensuradas em máxima intercuspidação (MIC.) a altura e largura da cabeça da mandíbula, o ângulo formado pelo centro da cabeça da mandíbula até a eminência articular do osso temporal, e o espaço biológico formado, pela cabeça da mandíbula a fossa mandibular do osso temporal. Os resultados levaram à conclusão de que, a utilização apenas da radiografia panorâmica modificada foi insuficiente para diagnósticos de problemas da região da A.T.M.
