The Efficacy of Platelet-Rich Fibrin (PRF) on Healing Following Surgical Removal of Third Molar TeethPedro-Beech, Kim January 2021 (has links)
Magister Scientiae Dentium - MSc(Dent) / Aim: A clinical trial to determine the post-operative outcomes of a PRF-treated socket versus
a conventionally treated socket following surgical removal of third molar teeth.
Introduction: Third molar surgery is a procedure many have to endure and which often results
in prolonged healing time with consequential absence from work and school. This has
motivated clinicians to seek methods to enhance the healing process and in effect, reduce the
healing time. Research on the use of PRF in enhancing wound healing in maxillofacial and oral
surgery have shown varying results. Therefore, this study was conceived to ascertain the effect
PRF has on the post-operative sequelae of third molar teeth.
Materials and Methods: This was a split mouth, prospective, single blinded, randomized
control trial. The study sample was made up of 26 patients (N=26) who met the inclusion
criteria. Four of the patients experienced neurosensory fallout of an associated nerve and were
subsequently excluded from the sample. This resulted in the total sample size of twenty-two
patients (n=22). Symmetrically impacted maxillary and mandibular third molars were removed
under general anaesthesia. Patients were treated in a within subject design: when one side of a
patient was treated with PRF, the other side was conventionally treated and acted as a control.
The allocation of the side treated with PRF was 'random'. Patients were followed-up on Day 2
and Day 7, respectively. Pain scores were recorded on a visual analogue scale (VAS) using 0
to 10 pain score. Swelling, wound dehiscence, development of alveolar osteitis, wound
infection and post-operative bleeding were compared between the intervention and control
side.
Results: Twenty-two patients (females = 13 and males = nine) b

Previous issue date: 2003 / Resumo: No planejamento das exodontias de terceiros molares mandibulares inclusos, talvez a maior preocupação do operador esteja relacionada com o controle da dor e edema pós-operatórios, redução do grau de ansiedade dos pacientes e prevenção de infecção da ferida cirúrgica. Neste sentido, o presente trabalho teve por objetivo avaliar a eficácia de dois protocolos farmacológicos que pudessem atender às necessidades citadas. Para tal, foram selecionados 20 sujeitos saudáveis, com indicação para a remoção bilateral dos terceiros molares mandibulares inclusos, em posição similar. Para o controle da dor, receberam rofecoxib 50 mg ou betametasona 4 mg, uma hora antes de cada intervenção, de forma aleatória, duplo-cega e cruzada. No mais, em ambas as intervenções, os pacientes receberam o mesmo tratamento farmacológico complementar: diazepam 5 mg como ansiolítico e aplicação local de uma solução aquosa de digluconato de c1orexidina 0,12% para prevenir complicações infecciosas da ferida cirúrgica. Foi prescrito paracetamol 750 mg para o caso de dor residual após a intervenção. A dor pós-operatória foi avaliada por um período de 24 horas, por meio de uma escala verbal descritiva e pelo consumo de analgésico no período pós-cirúrgico. O grau de ansiedade foi avaliado por meio da aplicação da Escala de Ansiedade de Corah (modificada). A incidência de infecção pós operatória foi caracterizada pela presença de dor aguda e trismo. Os resultados mostraram que o rofecoxib e a betametasona são drogas eficazes na prevenção da hiperalgesia. O diazepam por sua vez, parece ter contribuído para a redução da ansiedade em apenas parte dos sujeitos da amostra. Nenhuma complicação infecciosa foi observada no período pós operatório, como efeitos adversos da medicação empregada. Concluiu-se que ambos os protocolos farmacológicos são eficazes e seguros para serem empregados em cirurgias de terceiros molares mandibulares inclusos / Abstract: On planning the mandibular impacted third molar surgery, one of the major maybe concerns of the surgeons is related to the prevention of swelling, pain control, decreasing of the patients' anxiety degree and prevention of the infection of the surgical wound. This way, the aim of the present work was to assess the efficacy of two pharmacological protocols that could attend the previously mentioned needs. For that, 20 healthy people, that had been scheduled to undergo removal of bilateral impacted mandibular third molars, in the same position. One hour before the surgery the patients were randomly given either 4 mg betamethasone or 50 mg rofecoxib, to the pain control in a double blind crossed-over study. Furthermore, in both procedures, patients were given the same additional pharmacological treatment: 5 mg diazepam, as ansiolitic drug and 0.12% chlorhexidine digluconate rinses to prevent possible infection complications in the surgical wound. When considered necessary, it was advised the intake of 750 mg paracetamol to relief the residual pain after surgery. The postoperative pain was assessed in a period of 24 hours, by a 4 verbal rating scale and through of analgesic intake after the surgery. The "Corah modified" anxiety scale was used to evaluate the anxiety degree. The postoperative infection incidence was expressed by acute pain and trismus. The results showed that both rofecoxib and betametasona are efficacious to prevent hiperalgesia also that diazepam seemed to have contributed to the reduction of anxiety in just part of the sample subjects. No infectious complications were observed, also adverse drugs effects. We carne to the conc1usion that both protocols are safe and effective to be used in mandibular impacted third molar surgery / Doutorado / Farmacologia, Anestesiologia e Terapeutica / Doutor em Odontologia
