Use of a ceramic surgical bur for dental implant uncovering: A pilot randomized controlled trial Marco Aurélio Mena, Caio Vinicius Roman-Torres, Yeon Jung Kim, Luiz Felipe Palma, Vinicius Resende Ferreira, Luana de Campos Journal of Indian Society of Periodontology, 2025 Background: Dental implant uncovering, also referred to as second-stage surgery, is a minor surgical procedure traditionally performed using scalpels, which may result in bleeding and postoperative discomfort. In recent years, alternative techniques such as the use of surgical burs have been introduced, aiming to provide more comfortable and faster procedures, along with improved esthetic outcomes. However, scientific evidence regarding these alternative methods for dental implant uncovering remains limited, and certain clinical aspects are still a concern. The present study aimed to evaluate clinical outcomes associated with the use of a ceramic surgical bur for implant uncovering – specifically, thermal changes and postoperative pain – in comparison with the conventional technique employing a circular scalpel punch as the control. Materials and Methods: Ten single-unit osseointegrated implants, fully submerged beneath gingival tissue, were included and divided into two groups: the scalpel punch group ( n = 5) and the ceramic bur group ( n = 5). In addition, three specimens of residual soft tissue were collected from each group for histological analysis. Results: The results revealed no differences in any of the evaluated clinical parameters between the two groups, and no thermal damage was observed in the histological specimens. Conclusion: Based on these findings, the use of ceramic surgical burs for dental implant uncovering appears to be a safe technique, demonstrating comparable outcomes to the conventional scalpel method. Nevertheless, further studies are necessary to draw more definitive conclusions.
Physical and chemical evaluation of titanium surfaces with nanotopography using mechanical decontamination methods: in vitro study Viviane Maria RANKEL, Nelson Luiz de MACEDO-JÚNIOR, Edson GRACIA-NETO, Caio Vinicius Gonçalves ROMAN-TORRES, Humberto Osvaldo SCHWARTZ-FILHO Revista De Odontologia Da UNESP, 2025 Resumo Introdução Métodos de descontaminação utilizados em implantes podem exercer impacto direto sobre as superfícies de titânio, gerando alterações físico-químicas decorrentes da instrumentação mecânica. Objetivo O objetivo do estudo foi analisar, pelas técnicas de microscopia eletrônica de varredura (MEV) e energia dispersiva de raios X (EDS), a modificação de superfície de titânio, tanto física como quimicamente, após a ação de métodos de instrumentação mecânica preconizados para descontaminação de implantes. Material e método Quinze discos de titânio foram divididos em cinco grupos, tendo três discos cada grupo, conforme a forma de tratamento (grupos: controle, cureta aço inox, cureta de titânio, ultrassom e laser de diodo). Assim, foram aplicados os diferentes métodos e feita a análise de possíveis alterações morfológicas (MEV) e de constituição química (EDS) nas amostras. Resultado Em relação à morfologia, comparando-se ao grupo controle, os resultados mostraram uma alteração mais significativa no grupo em que o ultrassom foi utilizado. As curetas de titânio causaram um desgaste maior sobre as superfícies quando comparadas às curetas aço inox. Quimicamente, notou-se que o percentual de presença de elementos como Ti, O, C, F, Fe, Cr, Al e Si podem variar de acordo com os instrumentos aplicados nas superfícies. Os discos instrumentados com ultrassom apresentaram uma diminuição nos valores de Ti, aumento de O e geraram uma deposição de Fe e Cr. O uso de cureta de aço inox, cureta de titânio e a aplicação de laser não apresentaram diferenças significantes quando comparados ao controle. Conclusão Conclui-se que as diferentes formas de instrumentação mecânica avaliadas causam diferentes alterações, podendo modificar física e quimicamente as superfícies de titânio após sua aplicação.
Comparison of oral conditions between the Macuxi and Yanomami indigenous ethnicities Caio Vinicius Gonçalves ROMAN-TORRES, Richardson Mondego BOAVENTURA, Sergio Takashi KUSSABA, Doralice Severo da CRUZ, Wilson Roberto SENDYK, Debora PALLOS Brazilian Oral Research, 2025 In the state of Roraima, Brazil, indigenous populations have distinct cultural habits and ethnic characteristics compared to those of the nonindigenous population. Changes in the oral health of indigenous people are critical areas of investigation for generating oral health indicators, which significantly influence the overall health of this population, given their fundamental role in the development of public health policies. Our objective was to compare the oral conditions of indigenous people of the Yanomamis (YANs) and Macuxis (MACs) ethnicities in the state of Roraima. A total of 148 indigenous people were evaluated: 83 (53.50%) YANs and 65 (46.50%) MACs. All indigenous participants were assessed at the Indigenous Health House (CASAI), in the municipality of Boa Vista/RR, and data regarding oral condition, DMFT index, periodontal indices, basic erosive wear examination (BEWE) index, and eating habits were obtained. Significant differences were found in the DMFT index, which was higher for MAC individuals than for YAN individuals (P<0.05). Periodontal evaluation revealed a significantly larger probing depth in YAN individuals aged over 35 years. Plaque index was higher for YAN individuals, with a significant difference noted in all compared groups. As for the BEWE index, no statistically significant difference was observed between YAN and MAC individuals. With respect to eating habits, YAN individuals consumed significantly more native foods, whereas MAC individuals consumed predominantly processed foods. Periodontal indices are affected by poor oral hygiene, and oral hygiene instruction and guidance are necessary and could help reduce the incidence of dental caries and periodontal disease.

A Lipoma of Large Proportion in the Oral Cavity: A Case Report Vanessa Branco Gonçalves, Yuri Kalinin, Sumaya Bordalo, Marcelo Gaspar, Wilson Sendyk, Caio Roman-Torres Open Dentistry Journal, 2024 Background Lipoma is a benign neoplasm that can affect the whole body and rarely occurs in the oral cavity. It is slow-growing and asymptomatic, and conservative surgical treatment with total removal of the lesion is the treatment of choice. It originates from epithelial cells of mature adipose tissue. Case Presentation The aim of this study was to report a clinical case of a large lipoma in a 21-year-old male patient with melanoderma who presented a nodule in the region of the buccal vestibule extending from the region of the second molar to the ipsilateral canine, with an approximate size of 40 mm in its largest diameter in the anteroposterior direction and approximately 20 mm in diameter in the buccolingual direction. The initial diagnostic hypothesis was based on an ultrasound of the face, which detected a solid, circumscribed, echogenic nodule compatible with a lipoma of the face. Surgical treatment with excisional biopsy was chosen. The histopathological examination revealed fragments with the presence of discrete acanthosis and clear hyperkeratosis in the epithelium, along with the proliferation of mature adipocytes constituting a neoplastic parenchyma surrounded by a stroma. Conclusion The findings have confirmed the diagnosis of oral lipoma. The patient has evolved with a good prognosis and remained under follow-up without recurrence or sequelae. The present report has corroborated what has been observed in similar cases described in the literature regarding recurrence and excellent prognosis.
Evaluation of lip diseases in peddlers on two beaches of Guarujá/Brazil: An observational study Caio Vinicius G. Roman-Torres, Edson Gracia Neto, Angelica Castro Pimentel, Humberto Oswaldo Schwartz-Filho, Wilson Roberto Sendyk, Luana Campos Brazilian Dental Journal, 2024 Sun exposure is responsible for most lip lesions and, when diagnosed late, the prognosis is unfavorable. Treatments are usually mutilating, palliative, and expensive. This study aimed to evaluate the prevalence of lip diseases and factors associated with its development in peddlers on two beaches of the Guarujá/Brazil coast. Data were collected by clinical examination and use of a questionnaire of 182 peddlers on the beaches. They also received an explanatory folder with information about oral care, and the importance of the use of sunscreen for cancer prevention. All workers diagnosed with lip injuries were referred for dental treatment. The prevalence of lip alterations was 40.7% (n = 70), furthermore, smokers included 27.5%, and alcohol consumption was 20.3%. Regarding selfie protection, 72% of workers reported wearing a hat or cap frequently, 48.4% reported using body sunscreen, and only 11.5% reported using lip balm. There were no significant differences in factors such as alcoholism and smoking related to lip lesions diagnosis. However, when characterizing these factors, 48.6% of those who drink, or smoke have lip alterations. It can be concluded that the population of peddlers on the beaches of Guarujá has a high rate of lip alteration which suggests the need to implement educational health strategies aimed at informing the population about risk factors and preventive measures for lip diseases.

Dental Care during the COVID-19 Pandemic Caio Vinicius G. Roman-Torres, Marcelo de Melo Quintela Coronaviruses, 2021 Background: The rampant spread of SARS-CoV-2 worldwide increases the likelihood that dental health care professionals will treat this subset of the patient population. Due to the characteristics of the profession and the virus, two situations deserve attention: the disinfection of surfaces that can be contaminated during dental treatment and the presence of the virus in the oral cavity and the countless possibilities of microbial interaction with microorganisms in the oral cavity. Objective: The objective of this review was to point out the current stage of the discussion on dental biosafety involving professionals, the work team and patients. Methods: The following databases were consulted: MEDLINE (National Library of Medicine, USA - NLM), Lilacs, Scielo, Embase, Web of Science and Google Academic with the keywords COVID-19 and dental practice, dentistry, oral conditions, mouthrinses. Results: Disinfection of surfaces has always been paramount and the protocol to prevent the spread of SARS-CoV-2 seems to be established. SARS-CoV-2 is vulnerable to oxidation, it is recommended to use a mouth rinse containing oxidizing agents. Conclusions: Dentists are among the professionals who are most at risk of COVID-19 infection, and they must have extra attention during this period, biosafety measures must be reinforced and patients must be motivated to maintain a strict oral hygiene routine so that there is no accumulation of biofilm and this may somehow interfere with their systemic condition.
Rehabilitation of atrophic posterior mandible with vertical ridge augmentation with resorbable membrane: Case report with 3-year follow-up Ricardo Andrés Landázuri Del Barrio, Luciano Nascimento Braga Miziara, Alia Oka Al Houch, Wilson Roberto Sendyk, Caio Vinicius Gonçalves Roman-Torres, Angélica Castro Pimentel, Heloisa Fonseca Marão Open Dentistry Journal, 2021 Background: The placement of implants in the posterior mandible with the vertical bone defect can be associated with inadequate crown height space. Therefore, the vertical bone reconstruction of these defects is often necessary, although this procedure is technically challenging. Methods: A 49-year-old patient attended a private dental office for rehabilitation of an atrophic posterior mandible. The clinical and tomographic findings show absence of teeth #36, #37, #46, #47, and #48 with severe atrophy. Vertical bone augmentation was performed by using the guided bone regeneration technique with pericardium resorbable membrane followed by placement of short implants. The free gingival graft was performed, and after three months, screw-retained lithium disilicate single ceramic crowns were manufactured. Results: After a 3-years follow-up, bone loss around the implants or presence of gingival inflammation was not observed, and the prosthesis adaptation was found to have no alteration either. Therefore, aesthetics, as well as masticatory and speech functions, were preserved. Conclusion: There was no bone loss around the implants. The association between vertically guided bone regeneration using pericardium resorbable membrane is an alternative technique, and it avoids complications related to non-resorbable membrane exposure. It was shown to be viable after a 3-year follow-up.
