Comparing the periodontal clinical effect between conventional and self-ligating brackets: systematic review and meta-analysis

Introduction: orthodontists constantly seek to reduce the duration of their provided treatments and the patient's time in the office. for this reason, different bracket systems are currently used in orthodontics; an example is self-ligating brackets (SLB) which are believed to offer advantages over conventional brackets (CB). objective: to evaluate and compare the clinical periodontal effect of CB and SLB through a systematic review and a meta-analysis. material and method: a search of the literature was carried out until December 2017, in the biomedical databases: PubMed, Embase, SciELO, ScienceDirect, SIGLE, LILACS, BBO, Google Scholar and the Cochrane Central Register of Controlled Trials. the selection criteria of the studies were defined as such: randomized clinical trials, up to 5 years old and that report the clinical effects (probing depth, bleeding on probing, gingival index and plaque index) from the use of CB and SLB. the risk of study bias was analyzed through the Cochrane Handbook of systematic reviews of interventions. results: the search strategy resulted in 12 articles, eight of which reported no difference in the reduction in probing depth, bleeding on probing, gingival index and plaque index (p>0.05) between CB and SLB. conclusion: the literature reviewed suggests that there are no differences in the periodontal clinical effect among patients who received orthodontic treatment with CB or SLB.

Association between periodontal disease and polycystic ovary syndrome: a scoping review

Background: polycystic ovary syndrome (PCOS) is one of the most prevalent endocrine disorders in women. it is believed that sex hormones play a role in the maintenance of bone mass and directly or indirectly influence several cell types, including periodontal cells. objective: to evaluate the association between periodontal disease and PCOS according to the evidence reported in the last decade. material and method: a search was made in the biomedical databases: Pubmed, Embase, Scopus, SciELO, Science Direct and SIGLE for the 2007-2017 period. selection criteria: prospective and retrospective studies reporting the relationship between periodontal disease and PCOS. the methodological quality of the studies was analyzed using the critical appraisal skills program scale. results: 10 articles were found: 1 clinical trial and 9 case-control studies. the number of patients ranged from 48 to 196, mean age between 23.3 and 28.1 years, age range between 15 and 45 years. studies were conducted in Turkey, India and Iran. all the studies presented good methodological quality and a positive association between PCOS and periodontal disease. conclusion: PCOS shows a positive and significant association with the clinical and molecular parameters of periodontal diseases.

Clinical effect of platelet rich fibrin in the treatment of periodontal intrabony defects. systematic review and meta-analysis

Background: There is currently no gold standard biomaterial for the treatment of periodontal intrabony defects (PIDs). One of the current options is the use of platelet-rich fibrin (PRF). Objective: To determine the clinical effect of PRF in the treatment of PID through a systematic review and meta-analysis. Materials and Methods: A literature search was conducted up to February 2017 in the following biomedical databases: Pubmed, Embase, Scielo, Science Direct, SIGLE, LILACS and in the Cochrane Central Register of Clinical Trials. The selection criteria included: randomized clinical trials published in the last 5 years, reporting clinical effects (probing depth, clinical insertion level or gingival recession), with a follow-up time equal to or greater than 6 months, and sample size larger than or equal to 10 patients reporting the use of PRF as a treatment for PID. The methodological quality of the studies was analyzed using the Cochrane Handbook of Systematic Reviews of Interventions as a reference. Results: The search strategy yielded 20 articles. A reduction in probing depth and an increase in clinical insertion level or a reduction in gingival recession is reported, when using PRF alone or in combination with another biomaterial or substance that stimulates tissue regeneration. Conclusion: The literature suggests that the use of PRF in the treatment of PIDs has a beneficial clinical effect when compared to control treatments.

Clinical effect of platelet rich plasma in the treatment of periodontal intrabony defects. systematic review and meta-analysis

Introduction: One of the consequences of periodontitis is periodontal intrabony defects (PID). Various biomaterials have been used for its treatment, but there is still no biomaterial considered as the gold standard. Current research is focused on the use of platelet-rich plasma (PRP) for the treatment of PID. Objective: To determine the clinical effect of PRP in the treatment of PID through a systematic review with meta-analysis. Materials and Methods: A literature search was conducted until February 2017 in the biomedical databases: Pubmed, Embase, Scielo, Science Direct, SIGLE, LILACS, IBECS, and the Cochrane Central Register of Clinical Trials. The criteria for the selection of the studies, which were randomized clinical trials, were the following: articles or papers published in the last 5 years, reporting clinical effects, with a follow-up time equal to or greater than 6 months, and a sample size equal to or greater than 10 patients reporting the use of PRP as a treatment for PID. The methodological quality of the studies was analyzed using the Cochrane Handbook of Systematic Reviews of Interventions as a reference. Results: The search strategy yielded nine articles reporting a reduction in probing depth and gingival recession, and an increase in clinical insertion level when using PRP alone or in combination with another biomaterial. Conclusion: The reviewed literature suggests that the use of PRP in the treatment of PID has a positive clinical effect.

Eagle syndrome: a narrative review / Síndrome de Eagle: una revisión narrativa

Abstract: painful disorders in the maxillofacial region are common in dental practice. Most of these conditions are not properly diagnosed because of inadequate knowledge of craniofacial and cervico-pharyngeal syndromes such as Eagle Syndrome. The aim of this review is to describe the general aspects, diagnosis and treatment of Eagle syndrome. Eagle syndrome or stylohyoid syndrome was first described by Watt W. Eagle in 1937. It was defined as orofacial pain related to the elongation of the styloid process and ligament stylohyoid calcification. The condition is accompanied by symptoms such as dysphonia, dysphagia, sore throat, glossitis, earache, tonsillitis, facial pain, headache, pain in the temporomandibular joint and inability to perform lateral movements of the neck. Diagnosis and treatment of Eagle syndrome based on symptoms and radiographic examination of the patient will determine the need for surgical or nonsurgical treatment. Eagle syndrome is a complex disorder demanding a thorough knowledge of its signs and symptoms to make a correct diagnosis and provide an appropriate subsequent treatment. Disseminating information about this syndrome among medical-dental professionals is essential to provide adequate dental care to patients.

Resumen: en la práctica odontológica, es frecuente encontrar alteraciones con sintomatología dolorosa en la región maxilofacial, las cuales no son apropiadamente diagnosticadas, a causa del desconocimiento de síndromes craneofaciales y cervicofaríngeos, como el Síndrome de Eagle. El objetivo de esta revisión es describir los aspectos generales, diagnóstico y tratamiento del Síndrome de Eagle. El Síndrome de Eagle o estilalgia es la entidad nosológica, descrita por Watt W. Eagle en 1937, definida como aquel dolor orofacial relacionado con la elongación de la apófisis estiloides y calcificación del ligamento estilohioideo; el cual está acompañado de síntomas como: disfonía, disfagia, dolor faríngeo, glositis, otalgia, tonsilitis, dolor facial, cefalea, odinofagia, dolor en la articulación temporomandibular e imposibilidad de realizar movimientos laterales del cuello. El diagnóstico y tratamiento del Síndrome de Eagle está basado en la sintomatología y el examen radiográfico del paciente, lo cual determinará el tratamiento quirúrgico o no quirúrgico. El Síndrome de Eagle es una patología compleja que requiere un conocimiento amplio de sus signos y síntomas, para establecer un correcto diagnóstico y posteriormente un adecuado tratamiento. Para ello, es necesario difundir la información sobre este síndrome entre los profesionales médico-odontológico y así brindar una atención adecuada a cada uno de los pacientes.
