ABSTRACT: The objective of this study was to evaluate the relationship between oral health status and its impact on quality of life, and to suggest dental management strategies in patients undergoing antineoplastic therapy for onco-hematological diseases. A retrospective study including 33 individuals (age 9-79 yr) was conducted. It was observed that the dimensions related to physical pain, psychological discomfort, and social incapacity had statistically significant values. The most frequently performed dental treatments were periodontal treatment (45.45 %), dental restoration (36.36 %), tooth extractio n (33.33 %), and endodontic treatment (24.24 %). Thus, poor oral health directly affects the quality of life. Dental management should consider the aspects of the disease and antineoplastic treatment while aiming for safe and effective dental care.

RESUMEN: El objetivo de este estudio fue evaluar la relación entre el estado de salud oral y su impacto en la calidad de vida, y sugerir estrategias de manejo odontológico en pacientes sometidos a terapia anti-neoplásica por enfermedades onco-hematológicas. Se realizó un estudio retrospectivo que incluyó a 33 personas (de 9 a 79 años de edad). Se observó que las dimensiones relacionadas con dolor físico, malestar psicológico e incapacidad social tuvieron valores estadísticamente significativos. Los tratamientos dentales realizados con mayor frecuencia fueron el tratamiento periodontal (45,45 %), la restauración dental (36,36 %), la extracción dentaria (33,33 %) y el tratamiento endodóntico (24,24 %). Así, la mala salud oral afecta directamente la calidad de vida. El tratamiento dental debe tener en cuenta los aspectos de la enfermedad y el tratamiento antineoplásico mientras se busca una atención dental segura y eficaz.

ABSTRACT: Florid osseous dysplasia (FOD) is an extensive form of osseous dysplasia where normal trabecular bone is substituted by fibrous connective tissue and amorphous mineralized tissue. Usually, the lesions are mainly asymptomatic and the patients should be followed with clinical and imaging examination, requiring no intervention. Nevertheless, due to the poor vascularization of the lesion and local trauma, secondary infections and osteomyelitis may occur. Patients may present with pain, mucosal ulceration, and lesion exposure in the oral cavity, fistula and swelling. In such cases, correct diagnosis and management of the lesion is decisive to reestablish patient’s health and quality of life. The aim of this article is to present a case of complicating secondary chronic osteomyelitis treated successfully with conservative intervention. A 68-year-old black female patient reported a “swelling of the gums” that was present for eleven years, with episodes of periodic pain and swelling. On physical examination, a papule with suppuration in the alveolar mucosa in the right side of the mandible was observed. Panoramic radiography and CBCT showed a mixed lesion surrounded by sclerotic bone. The patient was diagnosed with chronic osteomyelitis in association with FOD and treated with antibiotic therapy together with surgical curettage. The incidence, etiophatology, differential diagnosis, treatment and prevention of secondary osteomyelitis associated with FOD are discussed in the light of literature. This information might assist the dentists while choosing the best treatment options for similar cases.

RESUMEN: La displasia ósea florida (DOF) es una forma de displasia del tejido óseo donde el hueso trabecular normal es sustituido por tejido conectivo fibroso y por tejido mineralizado amorfo. En general, las lesiones son de origen asintomático y los pacientes deben ser controlados con exámenes clínicos. Sin embargo, debido a la vascularización deficiente de la lesión y el trauma local, pueden ocurrir lesiones secundarias y osteomielitis. Los pacientes pueden presentar dolor, ulceración de la mucosa, lesión expuesta en la cavidad oral, fístula y edema. En estos casos, el diagnóstico adecuado y el tratamiento de la lesión es decisivo para estabilizar la salud y la calidad de la vida. El objetivo de este artículo fue presentar un caso de complicación secundaria crónica de la osteomielitis tratada con tratamiento conservador. Una paciente de 68 años de edad, negra, informa de "hinchazón de las encías" que presentaba durante once años, con episodios de dolor. En el examen intra-oral se observó una pápula con supuración en la mucosa alveolar del lado derecho de la mandíbula. Además de la radiografía panorámica y tomografía computarizada de haz cónico (TCHC) se tomaron muestras de la lesión debido a observación de hueso esclerótico. El paciente fue diagnosticado con una infección por osteomielitis en asociación con DOF y fue tratada con antibióticos, además de una cirugía curativa. En este artículo se presentaron la incidencia, el diagnóstico diferencial, el tratamiento y la prevención de los efectos secundarios de osteomielitis asociados con el DOF. La información de este trabajo podría ayudar a los dentistas en la aplicación del tratamiento indicado en casos similares.

RESUMO Este trabalho teve por objetivo verificar o efeito imediato da Estimulação Elétrica Neuromuscular (EENM) sensorial e motora, nas fases oral e faríngea da deglutição, em um homem de 64 anos, após tratamento de câncer de laringe. Foi realizado exame de videofluoroscopia durante a deglutição de 5 ml de mel e pudim, em três condições: sem estimulação, com EENM sensorial, com EENM motora, definidas de forma randomizada. Foi classificado o grau da disfunção da deglutição (DOSS), a presença de estase de alimentos (escala de Eisenhuber), de penetração laríngea e aspiração laringotraqueal (PAS), além da medida do tempo de trânsito oral e faríngeo, realizadas por uma avaliadora sem conhecimento sobre o estímulo aplicado. Na escala DOSS, houve melhora com a estimulação sensorial e motora. Na escala PAS, verificou-se melhora, tanto para o estímulo sensorial quanto motor na consistência mel, porém observou-se piora no estímulo motor para a consistência pudim. Houve diminuição dos resíduos em base de língua com estímulo sensorial e motor para as consistências pudim e mel; piora no estímulo motor na parede posterior da faringe para a consistência mel. Em relação ao tempo de trânsito oral e faríngeo, não foi observada diferença entre os níveis de estimulações. Os resultados demonstraram que a EENM em nível sensorial e motor melhorou o grau da disfagia em um indivíduo após o tratamento de câncer de laringe, com maiores benefícios do nível sensorial em relação ao motor no que diz respeito à presença de penetração e resíduos.

ABSTRACT The objective of this study was to verify the immediate effect of sensory and motor neuromuscular electrical stimulation (NMES), in the oral and pharyngeal phases of deglutition, in a 64 year male patient after laryngeal cancer treatment. Videofluoroscopy was performed during deglutition of 5 ml of honey and pudding, under three conditions: without stimulation, with sensory NMES, with motor NMES, randomly defined. The degree of dysfunction of deglutition (DOSS), the presence of food stasis (Eisenhuber scale), laryngeal penetration and laryngotracheal aspiration (PAS) and oral and pharyngeal transit time were evaluated. An evaluator without knowing about the applied stimulus. On the DOSS scale there was improvement with sensory and motor stimulation. In the PAS scale, there was improvement, both for the sensorial and motor stimulus in the honey consistency, but the worsening of the motor stimulus for the pudding consistency was observed. There was reduction of the residues in the base of the tongue with sensorial and motor stimulus for the consistency of pudding and honey; worsening motor stimulus in the posterior wall of the pharynx for honey consistency. There was no difference between stimulation levels regarding to oral and pharyngeal transit time. The results showed that NMES at the sensory and motor levels improved the degree of dysphagia in an individual after the treatment of laryngeal cancer, with greater benefits of the sensory level in relation to the motor regarding to the presence of penetration and residues.

RESUMO Objetivo Avaliar a saúde bucal de pacientes com câncer de cabeça e pescoço após tratamento antineoplásico, e compará-los com pacientes sem histórico de câncer. Métodos Foram avaliados 75 pacientes, divididos em Grupo de Estudo de indivíduos após tratamento antineoplásico (n=30) e Grupo de Controle de indivíduos sem histórico de câncer (n=45), com faixa etária de 35 a 79 anos. A condição de saúde oral foi avaliada pelo índice de dentes permanentes cariados, perdidos e obturados (CPOD), pelo índice periodontal comunitário e por uma avaliação de uso e necessidade de prótese, conforme critérios preconizados pela Organização Mundial da Saúde. A análise estatística foi descritiva e realizada por meio do teste do χ2 de Pearson. Resultados O índice periodontal comunitário foi maior no Grupo de Estudo quando comparado ao controle (p<0,0001). A necessidade de prótese superior (p<0,001) e inferior (p<0,0001) foi maior no Grupo de Estudo. O uso de prótese superior foi maior no Grupo de Estudo (p<0,002). O índice de dentes permanentes cariados, perdidos e obturados entre os dois grupos (p>0,0506) e o uso de prótese inferior (p>0,214) não apresentaram diferença estatística relevante. Conclusão A doença periodontal e o edentulismo são as alterações mais significativas em indivíduos que receberam terapia antineoplásica de câncer de cabeça e pescoço, assim como maior necessidade de reabilitação oral.

ABSTRACT Objective To evaluate the oral health of patients with head and neck cancer after antineoplastic treatment, and to compare them with patients with no history of cancer. Methods A total of 75 patients, divided into Study Group, composed of individuals after antineoplastic treatment (n=30), and Control Group, with individuals with no history of cancer (n=45), aged 37 to 79 years. The oral health status was evaluated through the index of decayed, missing or filled permanent teeth (DMFT), community periodontal index and evaluation of the use and need of prosthesis. All of these items were evaluated according to the criteria recommended by the World Health Organization. The statistical analysis was descriptive and used the Pearson’s χ2 test. Results The community periodontal index was higher in the Study Group when compared to the Control Group (p<0.0001). The need for an upper (p<0.001) and lower (p<0.0001) prostheses was higher in the Study Group. Also, the use of upper prosthesis was higher in the Study Group (p<0.002). The missing or filled permanent teeth index between the two groups (p>0.0506) and the use of lower prosthesis (p>0.214) did not present a relevant statistical difference. Conclusion Periodontal disease and edentulism are the most significant changes in individuals who received antineoplastic therapy for head and neck cancer as well as greater need for oral rehabilitation.

Abstract Idiopathic Bone Cavity (IBC) or Simple Bone Cyst (SBC) is a non- epithelialized bone cavity with serosanguinous fluid content or empty. There is a literature debate regarding its pathogenesis that remains unclear. The main treatment option is the surgical exploration, although there are successful cases described in the literature in which just a follow-up with clinical and radiographic evaluation was performed. Objective This study aimed to assess the spontaneous resolution of idiopathic bone cavity untreated by surgery. Material and Methods Twenty-one patients diagnosed with surgically untreated IBC were submitted to a follow-up protocol modified from Damante, Guerra, and Ferreira5 (2002). A clinical and radiographic evaluation was performed in 13 patients (13/21), while eight patients (8/21) were only radiographically evaluated. Three observers evaluated the panoramic radiographs of 21 patients and the Kappa test was performed by intra and inter-examiners. Inductive and descriptive statistics were applied to the results. Results Only one patient had a positive response to palpation and percussion of the teeth in the cyst area. Most of the cysts evaluated were rated as 3 (lesion “in involution”), 4 (lesion “almost completely resolved”), or 5 (“completely resolved”). Conclusions We observed progressive spontaneous resolution of IBC. Most cysts were found in the recovery process in different follow-up periods. Patient's follow-up, without surgery, may be considered after the diagnosis based on epidemiological, clinical, and radiographic features of the lesion.

OBJECTIVE: This study evaluated experimentally-induced periapical bone loss sites using digital radiographic and histopathologic parameters. MATERIAL AND METHODS: Twenty-seven Wistar rats were submitted to coronal opening of their mandibular right first molars. They were radiographed at 2, 15 and 30 days after the operative procedure by two digital radiographic storage phosphor plates (Digora®). The images were analyzed by creating a region of interest at the periapical region of each tooth (ImageJ) and registering the corresponding pixel values. After the sacrifice, the specimens were submitted to microscopic analysis in order to confirm the pulpal and periapical status of the tooth. RESULTS: There was significant statistically difference between the control and test sides in all the experimental periods regarding the pixel values (two-way ANOVA; p<0.05). CONCLUSIONS: The microscopic analysis proved that a periapical disease development occurred during the experimental periods with an evolution from pulpal necrosis to periapical bone resorption.

The identification of the mandibular canal (MC) is an important prerequisite for surgical procedures involving the posterior mandible. Cone beam computed tomography (CBCT) represents an advance in imaging technology, but distinguishing the MC from surrounding structures may remain a delicate task. OBJECTIVES: The aim of this study was to assess the visibility of the MC in different regions on CBCT cross-sectional images. MATERIAL AND METHODS: CBCT cross-sectional images of 58 patients (116 hemi-mandibles) were analyzed, and the visibility of the MC in different regions was assessed. RESULTS: The MC was clearly visible in 53% of the hemi-mandibles. Difficult and very difficult visualizations were registered in 25% and 22% of the hemi-mandibles, respectively. The visibility of the MC on distal regions was superior when compared to regions closer to the mental foramen. No differences were found between edentulous and tooth-bearing areas. CONCLUSIONS: The MC presents an overall satisfactory visibility on CBCT cross-sectional images in most cases. However, the discrimination of the canal from its surrounds becomes less obvious towards the mental foramen region when cross-sectional images are individually analyzed.

Pyogenic granuloma (PG) is a benign non-neoplastic mucocutaneous lesion. It is a reactional response to constant minor trauma and might be related to hormonal changes. In the mouth, PG is manifested as a sessile or pedunculated, resilient, erythematous, exophytic and painful papule or nodule with a smooth or lobulated surface that bleeds easily. PG preferentially affects the gingiva, but may also occur on the lips, tongue, oral mucosa and palate. The most common treatment is surgical excision. This paper describes a mucocutaneous PG on the upper lip, analyzing the clinical characteristics and discussing the features that distinguish this lesion from other similar oral mucosa lesions. The diagnosis of oral lesions is complex and leads the dentist to consider distinct lesions with different diagnostic methods. This case report with a 4 year-follow-up calls the attention to the uncommon mucocutaneous labial location of PG and to the fact that surgical excision is the safest method for diagnosis and treatment of PG of the lip, even when involving the mucosa and skin

O objetivo deste estudo foi avaliar as seqüelas bucais provocadas pela radioterapia em pacientes com neoplasias de cabeça e pescoço, tratados entre 1999 e 2003. Foram examinados 100 pacientes (24 mulheres e 76 homens), com idades entre 30 e 83 anos (média de 59,2 anos). O tempo desde a radioterapia variou de 1 a 72 meses (média de 28 meses). A média da dose total de radiação recebida pelos pacientes foi de 5.955 cGy. O protocolo de avaliação consistiu de anamnese, exame físico, aferição do fluxo salivar estimulado e pHmetria da saliva. Os sintomas referidos foram boca seca (68%), disfagia (38%) e disgeusia (30%). Em 64% dos indivíduos o valor médio do fluxo salivar estimulado esteve abaixo de 0.7 ml/min. O pH médio da amostra foi de 6.97 (± 0.714). O fluxo estimulado e a ocorrência de candidíase atrófica aumentaram conforme o aumento do tempo pós-radioterapia (p < 0.05). A ocorrência de mucosite esteve associada a maiores doses de radiação (p < 0.05). Dois casos de segundo tumor primário foram diagnosticados. O principal efeito da radioterapia na região de cabeça e pescoço foi a redução do fluxo salivar, apesar de nosso estudo ter demonstrado que há uma melhora tardia do fluxo salivar.

The aim of this study was to evaluate the oral sequelae of radiotherapy in patients treated between 1999 and 2003 for head and neck tumors. One-hundred patients (24 women, 76 men) ranging in age from 30 to 83 years (mean 59.2 years) were examined. Time since radiotherapy ranged from 1 to 72 months (mean 28 months). The total mean radiation dose received by the patients was 5,955 cGy. The evaluation protocol included anamnesis, intraoral and extraoral examination, measurement of stimulated salivary flow and salivary pH. Symptoms reported by the patients included dry mouth (68%), dysphagia (38%), and dysgeusia (30%). In 64% of the patients, the mean stimulated salivary flow rate was less than 0.7 ml/min. The mean salivary pH was 6.97 (± 0.714). Stimulated salivary flow increased with increasing postradiotherapy time (p < 0.05). The prevalence of mucositis was associated with higher radiation doses (p < 0.05), and the prevalence of atrophic candidiasis was related to a longer post-treatment period (p < 0.05). Two cases of recurrence of the primary tumor were detected during the study. The main effect of radiotheraphy in the head and neck region was a reduction of the salivary flow rate, even though our study demonstrated that there was a modest late improvement of the salivary flow.

OBJECTIVES: This study applied a simple method to evaluate the performance of three digital devices (two scanners and one digital camera) using the reproducibility of pixel values attributed to the same radiographic image. METHODS: Using the same capture parameters, a radiographic image was repeatedly digitized in order to determine the variability of pixel values given to the image throughout the digitization process. One coefficient value was obtained and was called pixel value reproducibility. RESULTS: A significant difference in pixel values was observed among the three devices for the digitized images (ANOVA, p<0.00001). There was significant pixel value variability at the same digitization conditions for one scanner and the digital camera. CONCLUSIONS: Digital devices may assign pixel values differently in consecutive digitization depending on the optical density of the radiographic image and the equipment. The pixel value reproducibility was not satisfactory as tested for two devices. It is maybe advisable knowing the digitization variations regarding pixel values whenever using digital radiography images in longitudinal clinical examinations.
