RESUMEN

BACKGROUND: The authors describe a technique for building an alternative jawbone phantom using dental gypsum and rice for research and dental radiology instruction. AIM: To investigate the potential of an alternative phantom to simulate the trabecular bone aspect of the human maxilla in periapical radiographs. METHODS: Half-maxillary phantoms built from gypsum-ground rice were exposed to X-rays, and the resulting images (experimental group) were compared to standardized radiographic images produced from dry human maxillary bone (control group) (n = 7). The images were blindly assessed according to strict criteria by three examiners for the usual trabecular aspects of the surrounding bone, and significant differences between groups and in assessment reliability were compared using Fisher's exact and kappa tests (α = 0.05). RESULTS: The differences in the trabecular aspects between groups were not statistically significant. In addition, interobserver agreement among observers was 0.43 and 0.51 for the control and experimental groups, respectively, whereas intraobserver agreement was 0.71 and 0.73, respectively. CONCLUSION: The tested phantom seemed to demonstrate potential for trabecular bone image simulation on maxillary periapical radiographs.

RESUMEN

OBJECTIVE: To identify and compare the morphology and dimensions of the nasopalatine canal (NPC) of individuals with and without cleft lip and palate using Conical Beam Computed Tomography (CBCT) images and to relate the results to the type of cleft and tooth absences in the region. SETTING: This is a cross-sectional, analytical study with a retrospective sample. PATIENTS, PARTICIPANTS: 100 CBCT exams from patients with cleft lip and palate and 100 CBCT exams from patients without cleft lip and palate were used. INTERVENTIONS: The NPC was evaluated for its morphology and measurements in the coronal, sagittal, and axial reformatting of CBCT exams. RESULTS: It was obtained as a result that in the group of patients with a cleft, the shapes of funnel, banana, and needle of the NPC were more frequent than in the control group. Patients with cleft lip and palate had significantly a larger nasopalatine foramen and a larger NPC diameter, besides a significantly shorter NPC, compared to controls. In both groups, edentulous patients had less anterior maxillary bone thickness, when compared to patients with maxillary anterior teeth. Patients with clefts had a bone thickness buccal to the NPC less than in the control group. CONCLUSIONS: This study confirms the anatomical variability of NPC in patients with cleft lip and palate. This finding reinforces the need for thorough surgical planning of the anterior region of the maxilla, in CBCT exams, by the dentist.

RESUMEN

BACKGROUND: To evaluate the impact of oral health on the quality of life (QOL) of individuals undergoing cancer treatment at the time of diagnosis of medication-related osteonecrosis of the jaw (MRONJ). MATERIAL AND METHODS: The present cross-sectional study analyzed patients with MRONJ from 2013 to 2019. The collected data included demographic data, base disease, medications associated with MRONJ, route of administration and time of use, signs, symptoms, and tomographic features of acute MRONJ, staging according to American Association of Oral and maxillofacial Surgeons position paper 2014 (AAOMS), type of dental treatment performed, outcome, and the responses to the Oral Health Impact Profile questionnaire (OHIP-14). Statistical analysis was performed using the Tukey test to study the association between oral condition and the QOL. A p-value of less than 0.05 was considered statistically significant. RESULTS: The sample consisted of 16 medical records of patients with MRONJ. Psychological discomfort showed alarmingly significant results (p< 0.001) with strong negative impact on the QOL of the patients. Functional limitation was the least affected dimension (p = 0.747). The other dimensions did not show statistically significant results. CONCLUSIONS: MRONJ compromises oral health and negatively impacts the QOL, especially with respect to the psychological discomfort (worry and stress). The OHIP-14 questionnaire proved to be an effective tool in the assessment of this impact. Key words:Medication-related osteonecrosis of the jaw, quality of life, oral health, OHIP-14.

RESUMEN

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 to local trauma, secondary infections and osteomyelitis may occur. Patients may present with pain, mucosal ulceration, lesion exposure in the oral cavity, fistula and swelling. In such cases, the 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 ósea donde el hueso trabecular normal es sustituido por tejido conectivo fibroso y tejido mineralizado amorfo. En general, las lesiones son de origen asintomático y los pacientes deben ser seguidos con el examen clínico. Sin embargo, debido a la pobre vascularización de la lesión y al trauma local, pueden producirse lesiones secundarias y osteomielitis. Los pacientes pueden presentarse con dolor, ulceración mucosa, lesión de exposición en la cavidad oral, fístula y edema. En estos casos, el correcto diagnóstico y tratamiento de la lesión es decisivo para reestabilizar la salud y la calidad de la vida. El objetivo de este artículo consistió en presentar un caso de complicación secundaria crónica de osteomielitis tratados con tratamiento conservador. El paciente, negro, de 68 años de edad, consulta por "hinchazón de las encías" que se presentó durante once años, con episodios de dolor. En el examen intraoral, se observó una pápula con supuración en la mucosa alveolar en el lado derecho de la mandíbula. La radiografía panorámica y CBCT mostraron una lesión mixta rodeada de hueso esclerótico. El paciente fue diagnosticado con osteomielitis crónica en asociación con DOF y fue tratado con tratamiento antibiótico junto con curetaje quirúrgico. La incidencia, la etiopatología, el diagnóstico diferencial, el tratamiento y la prevención de la osteomielitis secundaria asociada con DOF se discuten a la luz de la literatura. Esta información puede ayudar a los dentistas a elegir las mejores opciones de tratamiento para casos similares.

RESUMEN

OBJECTIVE: To evaluate the influence of rotation degree and field of view (FOV) size on the amount of artefacts produced in cone beam CT (CBCT) images. METHODS: A cylindrical wax utility phantom, with a metallic sample in its interior, was scanned with two FOV sizes (100 x 100 and 40 x 40 mm) and in full (360°) and partial (~180°) rotations. After the acquisitions, images were objectively assessed in the ImageJ software, obtaining the standard deviation in areas around the metal sample. The influence of artefacts produced by the several FOVs and rotation degrees was compared by two-way analysis of variance (α = 0.05). RESULTS: The images obtained with a large FOV presented a higher amount of noise compared to a restricted FOV, both for partial (p = 0.0037) and full (p = 0.0023) rotation degrees. For images obtained with a restricted FOV, full rotation resulted in images with less noise (p = 0.0259). For images obtained with large FOV, there was no statistically significant difference (p = 0.1494) in noise for both rotation protocols. CONCLUSIONS: As there were no significant differences in the amount of artefacts in rotation protocols for large FOVs, the partial rotation can be indicated due to its lower exposure to radiation. For acquiring images with restricted FOVs, the full rotation is recommended.

RESUMEN

Transverse maxillary deficiency is characterized by posterior uni or bilateral crossbite, crowded and rotated teeth, as well as high palate. Its treatment in adult individuals is surgically assisted rapid palatal expansion. The aim of this study was to verify the occurrence of dimensional alterations in the mandibular condyles of patients with TMD submitted to surgically assisted maxillary expansion. Measurements of the mandibular condyles using the DISTANCE tool in cone beam computed tomography iCat software were performed. The values obtained were submitted to statistical analysis by the paired t-test and the results showed statistically significant dimensional reduction in the axial posterior-anterior lateral (-0.74mm), axial posterior-anterior lateral left (-0.90mm) and coronal medium right (-1.24mm) dimensions. The coronal inferior (1.13mm), coronal inferior left (1.78mm) and coronal superior-inferior right (0.76mm) measurements showed statistically significant dimensional increase. The results allowed us to conclude that dimensional alterations occurred in the mandibular condyles in individuals with maxillary transversal deficiency that underwent surgically assisted rapid palatal expansion (SAPE), which can be understood by remodeling, since they are characterized by dimensional increase or reduction, depending on the location where the measurement was performed (AU)

RESUMEN

PURPOSE: Genial tubercles (GTs) are bony protuberances on the lingual aspect of the mandible symphysis, where genioglossus and geniohyoid muscles are inserted. In the literature, few papers report their real dimensions. Cleft lip and palate are craniofacial anomalies involving the maxilla, but the anatomical structures of the mandible can be altered when these have associated with the cleft, some syndrome. This study aimed to evaluate the GTs of 30 individuals and to make their measurements in cone beam computed tomography examinations. METHODS: A sample of 30 individuals, 19 of them with cleft lip and palate, 6 individuals with Treacher Collins syndrome (TCS), and 5 individuals with Pierre Robin sequence, was used. The GTs were evaluated about the amount and the following measurements were performed: A--distance from the apex of the central incisors to GT, B--mandibular thickness in the region of GT, C-GT height, D-GT width, and E--distance from inferior border of mandible to GT. RESULTS: The individuals presented since the absence of GTs to 3. The TCS group had the highest average of the measurements A, D, and E with statistical difference (P = 0.006) (P = 0.011) and (P = 0.017), respectively. The Pierre Robin sequence group had the highest average measurement of B and C, but there was no statistical difference. CONCLUSIONS: The difference in the measurements can be explained perhaps because individuals with TCS have glossoptosis and changes on retrognathic mandible, which would affect the position of the GT.

RESUMEN

The aim of this study was to evaluate the reproducibility of the gray values and noise of a direct digital radiography system (Visualix eHD) for various exposure times and analyzed regions. To obtain radiographic images in a standardized manner, the digital sensor of the system and a stepwedge were positioned in a phantom at a focus-film distance of 30 cm in a dental device at 70 kV, 7 mA and 2.2 mm filtration. Ten consecutive repetitions of X-ray imaging were performed at each exposure time (0.05, 0.07, 0.09 and 0.13 s). Gray values were analyzed using ImageJ software in five regions of interest (ROIs): alveolar bone (AB), soft tissue (ST) and three steps of the stepwedge (S1, S2 and S3). The results showed that both the variability of the gray values and the noise were statistically greater (p < 0.05) in the most radiolucent region (ST). Only the noise was affected by the exposure time. In conclusion, the reproducibility of the gray values and the noise of the Visualix eHD system can vary in specific areas with different radiolucency.

RESUMEN

The aim of this study was to identify the shape and route of the bony canal of the posterior superior alveolar artery (PSAA) and posterior superior alveolar nerve (PSAN) using different identification methods, including computed tomography (CT), panoramic radiograph, and macroscopic evaluation (corpse and dry skull). Twenty-four patients were analyzed by CT and panoramic and posterior anterior (PA) radiographs; additionally, 90 dry skulls and 21 dissected anatomical specimens were examined. Three-dimensional-CT revealed that the lateral wall of the maxillary sinus resembled a tunnel format in 60% of the treated patients. Out of all 24 patients, the panoramic radiograph identified the bony canal in only one patient; whereas the PA radiograph identified it in 80% of the patients. The dry skulls showed tunnellike routes of the PSAA and PSAN in 65% of the cases. Moreover, the pathway was also visibly observed in the dissected anatomical specimens as a straight shape in 85% of the cases. Thus, our results demonstrated that the most common shape of the bony canal of the PSAA and PSAN is the tunnel format with a straight route by 3D-CT, posterior anterior radiography, and macroscopic evaluation. However, in the panoramic radiographs, it was difficult to identify this canal.

RESUMEN

The aim of this study was to determine the efficacy of pixel value analysis using images generated by the Digora™ and Visualix™ systems for the early detection of external root resorption (ERR). Thirty extracted human lower incisors were radiographed using the Digora and Visualix systems; then, ERR was induced by immersing the teeth in 6 mol L-1 of hydrochloric acid for different periods of time (10, 30 and 60 minutes). ERR was confirmed by calcium quantification with an atomic absorption spectrophotometer. One digital image was acquired per time period at 70 kVp, 7 mA, 2.2 mm filtration, focus-film distance of 30 cm, and with exposure times of 0.09 s in the Digora system and 0.05 s in Visualix system. The region of interest was defined using ImageJ software. Statistical analysis was performed using ANOVA and Pearson's correlation (p < 0.05). There was no statistically significant difference between the time for ERR induction and the pixel values with either system. A positive correlation between the time of ERR induction and the calcium concentration was observed (r = 0.8892; p < 0.001). In conclusion, independent of the site of ERR induction and the digital system, pixel value analysis was not effective for ERR detection.

RESUMEN

We report two cases in which cone beam computed tomography (CBCT) was essential for the establishment of the diagnosis of periapical lesions. CBCT allows a three-dimensional assessment of a specific region with no superimposition of structures. Therefore, its use is recommended when radiographic images are not sufficient for the diagnosis.

RESUMEN

Purpose. The aim of this paper is to report a case in which the cone beam computed tomography (CBCT) was important for the confirmation of the presence of maxillary sinus septum and, therefore, the absence of a suspected pathologic process. Case Description. A 27-year-old male patient was referred for the assessment of a panoramic radiograph displaying a radiolucent area with radiopaque border located in the apical region of the left upper premolars. The provisional diagnosis was either anatomical variation of the maxillary sinuses or a bony lesion. Conclusion. The CBCT was important for an accurate assessment and further confirmation of the presence of maxillary septum, avoiding unnecessary surgical explorations.

RESUMEN

O reconhecimento do forâmen lingual lateral (FLL) e muito importante, especialmente na implantodontia. Assim, a tomografia computadorizada feixe cônico (TCFC) permite a visualização de estruturas anatômicas nao detectadas na radiografia convencional, com o FLL. Este artigo relata dois casos de FLL ambos no lado direito em dois pacientes distintos. Ambos os exames foram obtidos pelo I-Cat e avaliados no programa I-Cat Vision. A injúria aos vasos que atravessam a FLL pode causar hematoma no assoalho bucal e, em situações mais graves, a obstrução das vias aéreas superiores

Lateral lingual foramen (LLF) recognition is very important, especially to dental implant practitioners. In this way, cone-beam computed tomography (CBCT) allows visualization of anatomic structures not detected in conventional radiography, such as LLF. This paper reports two LLF cases both at the right side in two different patients. Both exams were obtained through I-CAT Classic device and evaluated with the I-CAT Vision software. Injuries to LLF contained vascular bundles might cause hematoma at the floor of the mouth and, in worst cases, subsequent upper airway obstruction.

RESUMEN

Objetivo: o objetivo deste estudo foi avaliar a prevalência das calcificações na artéria carótida – CACs – em imagens digitais panorâmicas (PD) e de tomografia computadorizada de feixe cônico (TCFC) dos mesmos pacientes. A CAC é uma doença vascular que acomete os pacientes acima dos 50 anos, coincidindo com uma grande maioria de pacientes que procura reabilitação por implantes. Assim sendo, é importante que o implantodontista esteja atento à interpretação da CAC, uma vez que detectada requer encaminhamento do paciente a um cardiologista para confirmação do diagnóstico. Material e métodos: foram avaliadas 100 imagens (200 lados) de panorâmicas digitais (idade média de 48 anos) e a imagem TCFC dos mesmos pacientes. O re-exame das imagens panorâmicas foi realizado com o objetivo de identificar os CACs falso-positivos e falso-negativos em relação à TCFC. Resultados: considerando 200 lados analisadas, 3,5% (n=7/200) foram interpretadas como CACs em radiografias panorâmicas, e 2,5% (n=5/200) em imagens de TCFC. Dos sete casos CACs positivos em radiografias panorâmicas, três foram falso-positivos quando comparados à correspondente TCFC. Quanto aos cinco casos CACs positivos em TCFC, um era falso-negativo, comparado à imagem panorâmica respectiva. Conclusão: calcificações artéria carótida – CACs – podem ser vistas nas imagens panorâmicas e/ou TCFC, no entanto, a panorâmica tendeu a mostrar casos falso-positivos da CAC. A CAC surge como um achado incidental nos exames de panorâmica e de TCFC, mas ainda assim o dentista tem como obrigação encaminhar o paciente para um cardiologista para a confirmação do diagnóstico, uma vez detectada a sua suposta presença.
