Post-surgical pain is a direct consequence of the surgical event, being closely related to inflammation after treatment, both manifesting itself in parallel. Nonsteroidal anti-inflammatory drugs have been considered the analgesic therapy of choice. Objective: To compare the analgesic effectiveness of ibuprofen against meloxicam after surgical intervention to remove the lower third molar. Materials and Methods: A total of 30 patients were assigned to the two treatment groups: 15 from to ibuprofen group and 15 to the meloxicam group. The first dose was administered at the end of the surgery and the necessary tablets were given to complete the 3-day drug treatment regimen, as well as 1 sublingual ketorolac tablet as rescue medication. Postoperative pain reduction was evaluated making phone calls to evaluate pain by using the numerical scale of pain at 24, 48, 72 hours and 7 days postoperatively. Results: Meloxicam is more effective over time, showing stable analgesic levels and less pain than the ones in ibuprofen group. However, its maximum effect takes longer, which explains that some patients required rescue medication in the first postoperative hours. Conclusions: Due to its analgesic, anti-inflammatory and antipyretic effect, we can consider meloxicam as a good alternative in postoperative pharmacological treatment. It is suggested the use of some other drug that achieves pharmacological synergy to optimize results or to use meloxicam based on preventive analgesia models.

Objetivo: El objetivo de este reporte de caso es utilizar la matriz dérmica acelular  como alternativa  para el cubrimiento radicular mediante el desplazado coronal. Material y métodos: Paciente de sexo femenino de 53 años de edad que acude a la Maestría de Periodoncia de la Facultad de Odontología en la Universidad Autónoma de Coahuila, Unidad Torreón con motivo de consulta: “se me bajó la encía y traigo mucha sensibilidad”. En el examen clínico se observan recesiones gingivales clase I de Miller en los OD 13, 11, 21 y 33, así como agenesia de incisivos laterales (12 y 22), se realiza la cirugía utilizando una matriz dérmica acelular para minimizar la incomodidad y dolor postoperatorios. Resultados: El uso de una matriz dérmica acelular ayuda a obtener resultados en cuanto a cobertura radicular similares a los del injerto de tejido conectivo autólogo en el manejo de recesiones múltiples de clase I de Miller, minimizando las molestias postoperatorias del paciente. Palabras clave: matriz dérmica acelular, colgajo desplazado coronalmente, cobertura radicular. DeCS [Internet]. ed. 2017.

Guided Bone Regeneration through the use of a membrane has been a Gold standard to obtain the best results, in turn, being a sensitive technique whose main complication is its exposure and infection by pathogenic periodontium bacteria. Objective: To observe the antimicrobial effect of topical chitosan-metronidazole on Porphyromona gingivalis. Materials and Methods: Topical Chitosan-Metronidazole was prepared with which it is antimicrobial sensitivity was observed in the crop medium of Müller-Hinton agar with the well diffusion method after having applied 50 microliters of P. gingivalis, 8mm was extracted with a punch and filled with chitosanmetronidazole, the inhibitory halo was analyzed to obtain results. Results: The inhibitory halo was observed and measured in the two samples which is 20 mm for both, obtaining a sensitive result. Conclusion: Topical chitosan-metronidazole was shown to have a good effect on P. gingivalis.

The objective of this clinical case report is to demonstrate the importance of the origin of an endodontic lesion, to know how to diagnose it correctly, as well as to work in a multidisciplinary way to arrive at a correct treatment plan. In this case, guided tissue regeneration is an excellent treatment option for intrabony defects. Case Report: 42-year-old female patient, healthy, attends the clinic of the Master of Periodontology of the Faculty of Dentistry of the Autonomous University of Coahuila, being referred from the endodontics department, since she presented injury to the dental organ left upper lateral incisor which had previously been treated endodontically, with a diagnosis of pulp necrosis, medicating intra canal with pure calcium hydroxide on two occasions, without presenting improvement, for which a computed tomography scan of the involved dental organ was requested, since the lesion did not subside and presented signs of inflammation, pain on percussion, with a periodontal probing greater than 8 mm and grade II mobility, for which it was decided to perform exploratory surgery, debriding the surrounding region of dental organ left upper lateral incisor, presenting a palatal groove that extended towards the cervical third of the root, it was decided to perform guided tissue regeneration, since the defect was contained, using autologous and alloplastic bone graft, as well as or platelet rich fibrin membrane, temporarily placing a dental splint to keep the teeth fixed. Result: A monthly radiographic study (periapical radiographs) was performed to assess the previously treated endodontic lesion and assess the greater amount of hard tissue formed in the periapical area of dental organ left upper lateral incisor and eliminating dental mobility, as well as pocket depth, taking the tooth to periodontal health.

This case report describes the successful treatment of multiple gingival recessions in the lower arch of a 29-year-old female patient using an acellular dermal matrix. The surgical procedure involved the use of local anesthesia, intrasulcular incisions, tunneling instruments, and 6-0 Vicryl and nylon sutures. The patient was prescribed antibiotics and analgesics and instructed to rinse with chlorhexidine. Follow-up care was provided, and the sutures were removed after 21 days. The patient achieved excellent coverage of the root surfaces and favorable aesthetic results, with stable periodontal tissues observed after two years. This report highlights the potential benefits of acellular dermal matrices for the treatment of gingival recessions.
