Association between the city region and traumatic dental injuries among adolescents from Santa Maria, South Brazil

Abstract This study investigated the association between the city region and traumatic dental injury (TDI) among adolescents from Santa Maria, Rio Grande do Sul, Brazil. A population-based cross-sectional survey was conducted from March to November 2018, which included a representative sample of adolescents (15-19-year-old) attending public and private high schools. A questionnaire on sociodemographic information was sent to the parents/legal guardians of the selected adolescents. TDI in the upper and lower permanent incisors and canines was recorded based on the O'Brien classification. Environmental variables (sociodemographic and structural characteristics of the neighborhoods) were obtained from official publications. Multilevel Poisson regression models were used, and prevalence ratios (PR) and 95% confidence intervals (CI) were calculated. A total of 1,146 adolescents participated in this study. The overall prevalence of TDI was 17.3%, mild trauma was 12.7%, and severe trauma was 5.8%. Adolescents living in the southern region had a prevalence of TDI of 25.3%, compared with 13.6% in the northern region. After adjusting for important cofactors, adolescents living in the southern region were more likely to have TDI than their counterparts in the northern region (PR, 1.91; 95%CI: 1.18-3.11; p = 0.009). Analyzing the number of environmental risk indicators in different regions, the southern region presented a higher mean and median than all other regions. In conclusion, living in the southern region was associated with a higher prevalence and severity of TDI among adolescents from Santa Maria, southern Brazil. Our findings suggest the role of the environment in the epidemiology of TDI.

Self-perceived neighborhood factors and OHRQoL among adolescents: a population-based study in southern Brazil

Abstract This study aimed to assess the relationship between self-perceived neighborhood factors and oral health-related quality of life (OHRQoL) among adolescents from southern Brazil. A representative sample of 15-19-year-old students from Santa Maria, Brazil, was included. The Oral Health Impact Profile (OHIP-14) was used to assess the OHRQoL. Self-perceived neighborhood factors were assessed through a structured questionnaire and included characteristics of the neighborhood where the adolescents lived, such as the presence of paved streets, tap water, community social networks, and availability of dental services and the Family Health Strategy (FHS). In addition, socioeconomic, behavioral, and clinical variables (dental caries and malocclusion) were also evaluated. Multilevel Poisson regression analysis with a hierarchical approach was used to assess the association between predictors and OHIP-14. The rate ratio (RR) and 95% confidence intervals (CIs) were estimated. A total of 1,197 adolescents were included in this study (participation rate: 72.3%). The mean OHIP-14 score was 8.4 (standard error = 0.2), ranging from 0 to 49. Living in residences with unpaved streets (RR = 1.11, 95%CI:1.06−1.17), no tap water (RR = 1.11, 95%CI: 1.02−1.20), absence of the FHS services (RR = 1.15, 95%CI: 1.09−1.20), and the availability of dental services (RR = 1.08, 95%CI: 1.03−1.14) were associated with higher OHIP-14 scores, indicating a poorer OHRQoL. In addition, lower socioeconomic status, visiting the dentist for curative reasons, lower frequency of brushing teeth, and higher sugar consumption were also associated with higher OHIP-14 scores. In conclusion, self-perceived neighborhood characteristics were associated with OHRQoL in adolescents. Adolescents who perceived their neighborhood as deprived had poorer OHRQoL.

Lesão Cancerizável com aspecto clínico de lesão benigna em paciente tabagista / Malignantly injury with clinical aspect of benign lesion in smoking patients

Introdução: a mucosa bucal e seus anexos são sedes de inúmeras doenças, quer de caráter local, quer representando manifestações bucais de doenças sistêmicas. Neste contexto as lesões com potencial de malignização estão associadas principalmente ao estilo de vida, como hábitos viciosos, consumo de alimentos em temperaturas elevadas e próteses mal-adaptadas. Objetivo: relatar o caso de uma lesão cancerizável com aspecto clínico de lesão benigna. Lesões encontradas na cavidade bucal com caráter de benignidade, devido ao estilo de vida do paciente e hábitos viciosos, podem ter potencial para malignização. O cigarro tem ação química e térmica sobre os tecidos, além de ser um dos principais fatores carcinogênicos com os quais o homem mantém contato por estar presente nas três fases da carcinogênese. Além do tabaco, o gênero, etnia e idade do paciente também estão associados à malignização de lesões bucais, sendo que pacientes masculinos, leucodermas e com mais de 50 anos de idade. são considerados pacientes com risco para malignização de lesões. Relato de caso: Paciente masculino, 65 anos de idade, leucoderma, procurou atendimento odontológico apresentando um nódulo em região de mandíbula, com hipótese diagnóstica clínica de lesão de células gigantes periférica, granuloma piogênico e fibroma de irritação. Optou-se pela biópsia excisional, a qual possibilitou o diagnóstico histopatológico de displasia epitelial severa. O paciente foi encaminhado para cirurgião de cabeça e pescoço e encontra-se em acompanhamento clínico de dois anos sem indícios de recidiva da lesão. Considerações finais: justifica-se a importância do cirurgião-dentista no diagnóstico precoce de lesões cancerizáveis, que por muitas vezes se apresentam sem sintomatologia dolorosa, e apenas ao exame clínico não é possível obter o diagnóstico, necessitando-se de exames complementares, como a biópsia.

Introduction: the buccal mucosa and its annexes are the site of many diseases, both of a local nature or being oral manifestations of systemic diseases. In this context, lesions with malignant potential are associated mainly with lifestyle, such as vicious habits, food consumption at elevated temperatures and maladaptive prostheses. Objective: this study aims to report the case of a cancerous lesion with a clinical aspect of benign lesion. Lesions found in the oral cavity with benignity due to the patient's lifestyle and vicious habits may have potential for malignancy. The cigarette has chemical and thermal action on the tissues, besides being one of the main carcinogenic factors with which the man maintains contact by being present in the three phases of the carcinogenesis. In addition to tobacco, the gender, ethnicity and age of the patient are also associated with the malignancy of oral lesions, and male, leukodermal and over 50-year-old patients are considered patients at risk for malignant lesions. Case report: a 65-year-old male patient, leucoderma, sought dental care presenting a nodule in the mandible region, with clinical diagnosis hypothesis of peripheral giant cell lesion, pyogenic granuloma and irritation fibroma. We chose the excisional biopsy, which made possible the histopathological diagnosis of severe epithelial dysplasia. The patient was referred to a head and neck surgeon and is in clinical follow-up for two years with no evidence of recurrence of the lesion. Final considerations: It is stressed the importance of the dental surgeon in the early diagnosis of cancerous lesions, which often present without pain symptomatology, and only when the clinical examination is not possible to obtain the diagnosis, we need complementary tests, such as biopsy.

Cisto periapical de grandes proporções na região anterior da maxila. Relato de caso / Periapical cyst major in the anterior maxilla. Case report

Introdução: o cisto periapical está relacionado ao ápice de um dente com necrose pulpar, ou seja, de natureza inflamatória e corresponde à frequência de 7% a 54% das imagens periapicais. Objetivo: relatar e discutir um caso de cisto periapical inflamatório invasivo na maxila, bem como as suas formas de tratamento. Relato de caso: paciente do gênero masculino, 48 anos de idade buscou atendimento odontológico relatando sentir dor no elemento dentário 23 e fístulas recorrentes na região do elemento dentário 22. Frente aos aspectos clínico e radiográfico, foram sugeridas as hipóteses diagnósticas de cisto periapical, tumor odontogênico ceratocístico, ou ameloblastoma. Devido ao laudo tomográfico de fratura radicular no elemento 22, a conduta clínica de escolha foi extração da raiz e exérese da lesão, seguidas de curetagem cuidadosa. O espécime foi encaminhado para análise histopatológica, tendo como resultado cisto periapical. Considerações finais: o cisto periapical é similar a outras lesões apicais o que dificulta o diagnóstico. Portanto é importante um exame clínico cuidadoso associado a exames complementares como, tomografia computadorizada, analisando-se assim, o caso minuciosamente a fim de oferecer ao paciente melhores condutas de tratamento.

Introduction: the periapical cyst is related to the apex of a tooth with pulpal necrosis, that is, of an inflammatory nature and corresponds to the frequency of 7% to 54% of the periapical images. Objective: this paper aims to report and discuss a case of invasive periapical inflammatory cyst in the maxilla, as well as its forms of treatment. Case report: a 48-year-old male patient sought dental care, reporting pain in the tooth 23 and recurrent fistulas in the region of the tooth 22. Facing the clinical and radiographic aspects, the diagnostic hypotheses of periapical cyst, tumor Odontogenic keratocystis, or ameloblastoma. Due to the tomographic report of root fracture in element 22, the clinical management of choice was root extraction and excision of the lesion, followed by careful curettage. The specimen was referred for histopathological analysis, resulting in periapical cyst. Final remarks: the periapical cyst is similar to other apical lesions, which makes diagnosis difficult. Therefore, a careful clinical examination associated with complementary exams such as computed tomography is important, and the case is carefully analyzed in order to offer the patient better treatment procedures.
