Item Piperacillin-Tazobactam as an Adjuvant in the Mechanical Treatment of Patients with Periodontitis: A Randomized Clinical Study(Antibiotics, 2022) Hurtado-Celotti, Dolores; Martínez Rodríguez, Natalia; Ruiz-Sáenz, Pedro Luis; Barona Dorado, Cristina; Juan Santos-Marino; José María Martínez-González; Martínez González, José MaríaIn this study, the aim was to evaluate the effects of the adjuvant piperacillin–tazobactam solution in the mechanical treatment of periodontitis. A single-blind split-mouth randomized study, it included 24 participants. All of them presented periodontitis stage III according to the 2018 World Workshop classification and the presence of at least one of the following periodontal pathogens: Aggregatibacter actinomycetemcomitans; Porphyromona gingivalis; Treponema denticola; Tannerella forsythia; Prevotella intermedia. The study established two groups: a control group (SRP: scaling and root planing) and a test group (SRP plus local piperacillin–tazobactam). The final recruitment included 11 women (45.8%) and 13 men (54.2%). The age range was between 25 and 72 years, and the mean age was 57 ± 10.20 years. Clinical controls were performed at 2 weeks, 3 months, and 6 months, repeating the SRP and applying the piperacillin–tazobactam solution again at the 3-month appointment. The clinical attachment level decreased by a mean of 2.13 ± 0.17 mm from the baseline to 6 months in the test group versus 1.63 ± 0.18 mm in the control group. The mean probing pocket depth decreased from 1.32 ± 0.09 mm in the test group, versus from 0.96 ± 0.14 mm on the control side. The plaque index in the test group decreased by 0.46 ± 0.04, while it decreased by an average of 0.31 ± 0.04 in the control group. In conclusion, the local use of piperacillin–tazobactam as complementary therapy produces better clinical results in patients with periodontitis. However, these results are not maintained over time, and so a more persistent local application is necessary.Item Dental considerations in diagnosis of maxillary sinus carcinoma: A patient series of 24 cases(The Journal of the American Dental Association: J Am Dent Assoc: JADA, 2018) Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Cortés Bretón Brinkmann, Jorge; Martín Ares, María; Sanz Alonso, Javier; Martínez González, José MaríaBackground Maxillary sinus carcinoma is a rare entity with an incidence of 0.2% and a low patient survival rate due to the frequency of late diagnosis. Methods In this multicenter, transversal, retrospective, observational study, the authors analyzed patients who had received a diagnosis of maxillary sinus carcinoma, registering their oral symptoms, histologic type, treatment efficacy, and survival rate. Results Maxillary sinus carcinoma was diagnosed in 24 patients (15 men and 9 women), of which 75% were squamous cell carcinomas. All patients had dental mobility, and some had swelling, orosinus fistula, or some dental loss. Mean patient survival rate was 38.83 months. Conclusions A history of pain or swelling of unknown origin, an unexplained widening of periodontal ligament space, or mobility of the teeth should be considered warning signs of maxillary sinus carcinoma. Practical Implications Recognition of oral symptoms by the dentist would help in making an early diagnosis of maxillary sinus carcinoma, improving the patient’s chances of survival and quality of life.Item Analysis of the Radiological Changes of the Sinus Membrane Using Cone Beam Computed Tomography and Its Relationship with Dental Treatments. A Retrospective Study(Biology, 2022) Rey-Martínez, María Helena; Ruiz-Sáenz, Pedro Luis; Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Meniz García, Cristina María; Cortés Bretón Brinkmann, Jorge; Suárez-Quintanilla, Juan Antonio; Martínez González, José MaríaThe aim of this study was to identify the most relevant dental factors and iatrogenic causes in the development of pathological changes to the sinus membrane and to analyse their possible influence on the development of odontogenic sinusitis. A descriptive, observational study was designed, with 276 patients who had been evaluated via cone beam computed tomography, analysing possible sinus thickening factors, such as apical infections, endodontic treatments, periodontitis, radicular cysts and impacted teeth, as well as iatrogenic factors caused by implant treatments or the development of oroantral communications produced during tooth extraction manoeuvres. Among the dental factors, periodontitis (47.1%), apical pathology (23.5%) and endodontic treatments (23.1%) were the predominant causes of sinus membrane thickening that most frequently produced an occupancy between 2 and 10 mm. Regarding the implant treatments, the placement of implants through the floor of the maxillary sinus was the main cause (9.8%), followed by sinus elevation techniques (6.2%). Dental extraction was the first cause of oroantral communication (5.0%), being the procedure that caused the greatest thickening of the sinus membrane. This study highlights the importance of dental treatments and iatrogenic factors in sinus pathology, and the need for diagnostic interrelations between the different specialists who address this pathology.- Project number: 108
Item Guía para la solución de errores frecuentes en la docencia práctica de cirugía bucal(2022) Barona Dorado, Cristina; Baca Pérez-Bryan, Rafael; Cortés-Bretón Brinkmann, Jorge; Fernández Cáliz, Fernando; González Álvarez, Marina; Jiménez Saro, Paula; Leco Berrocal, María Isabel; López Díez, Belén; Martínez González, José María; Martínez Rodríguez, Natalia; Meniz García, Cristina MaríaLa Cirugía Bucal es una disciplina que se imparte en el Grado de Odontología, en tercer y cuarto curso. Sirve como base y aporta conocimientos previos para cursar otras asignaturas optativas de quinto curso, como la Cirugía Maxilofacial y la Implantología. Asi mismo, es la asignatura donde se imparten los contenidos de Anestesia Local, prodecimiento imprescindible para realizar cualquier procedimiento terapéutico en los tratamientos odontológicos. En el desarrollo de la misma, la ejecución práctica de los conocimientos se pone en marcha en cuarto curso. A lo largo de los años, los profesores implicados en la docencia práctica de la asignatura, hemos observado una serie de errores que se repiten en todas las promociones. Para ayudar al estudiante a prevenir estos errores, se va a elaborar una guía de errores comunes, que se puede actualizar cada curso académico, que le permita conocerlos antes de enfrentarse a la práctica clínica. Item Calcium phosphate modified with silicon vs. bovine hydroxyapatite for alveolar ridge preservation: Densitometric evaluation, morphological changes and histomorphometric study(Materials (Basel, Switzerland), 2021) Cadenas-Vacas, Guillermo; Martínez Rodríguez, Natalia; Barona Dorado, Cristina; Sánchez-Labrador, Luis; Cortés Bretón Brinkmann, Jorge; Meniz García, Cristina María; Martínez-González, José MaríaAfter tooth extraction, the alveolar bone undergoes a physiological resorption that may compromise the future placement of the implant in its ideal position. This study evaluated bone density, morphological changes, and histomorphometric results undergone by alveolar bone after applying a new biomaterial composed of calcium phosphate modified with silicon (CAPO-Si) compared with hydroxyapatite of bovine origin (BHA). Alveolar ridge preservation (ARP) was performed in 24 alveoli, divided into a test group filled with CAPO-Si and a control group filled with BHA. Three months later, the mineral bone density obtained by the biomaterials, horizontal and vertical bone loss, the degree of alveolar corticalization, and histomorphometric results were evaluated. Both biomaterials presented similar behavior in terms of densitometric results, vertical bone loss, and degree of alveolar corticalization. Alveoli treated with CAPO-Si showed less horizontal bone loss in comparison with alveoli treated with BHA (0.99 ± 0.2 mm vs. 1.3 ± 0.3 mm), with statistically significant difference (p = 0.017). Histomorphometric results showed greater bone neoformation in the test group than the control group (23 ± 15% vs. 11 ± 7%) (p = 0.039) and less residual biomaterial (5 ± 10% vs. 17 ± 13%) (p = 0.043) with statistically significant differences. In conclusion, the ARP technique obtains better results with CAPO-Si than with BHA.
