ABSTRACT
In 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.
ABSTRACT
Los quistes dentígeros son frecuentes y aparecen en relación a un diente retenido. Al ser el tercer molar inferior el diente que sufre retención más comúnmente, la localización es mandibular en el 70 % de los casos y normalmente son asintomáticos. Se presenta un caso de una paciente de 63 años de edad que acude a la consulta con anestesia hemilabial derecha, a la que, tras el estudio radiológico donde se observaron lesiones compatibles con quiste dentígero, se le realizaron la extracción de los terceros molares inferiores junto con la quistectomía. Se hace una revisión de la literatura para conocer los aspectos más importantes de estos quistes como etiología, clínica y tratamiento más adecuado, así como de los métodos diagnósticos y opciones terapéuticas para trastornos del nervio dentario inferior (AU)
The dentigerous cysts are common and they appear associated with impacted teeth. Being the lower third molar the tooth that suffers retention more commonly, the location is mandibular in 70 % of cases and they are usually asymptomatic. A case of a 63 year old woman who came to the dental office with right mandibular anesthesia is reported. Radiographic evaluation revealed lesions compatible with dentigerous cyst so the extraction of third molars and cystectomy were performed. The literature is reviewed to know the most important features of these cysts such as etiology, clinical symptoms and most appropriate treatment as well as diagnostic methods and treatment alternatives for disorders of the inferior alveolar nerve (AU)
