SUCCESS RATE OF ENDODONTIC TREATMENTS PERFORMED BY UNDERGRADUATE STUDENTS OF THE UNIVERSITY OF SOUTHERN SANTA CATARINA

Introduction: Apical periodontitis is an inflammatory disease of the periradicular tissues caused by microbial(re)contamination of the root canal system. Due to its direct relationship to the quality of endodontictreatment, it is extremely important to carry out longitudinal and cross-sectional studies, following-uptreatments carried out in universities. Aim: To evaluate the success rate of endodontic treatments performedby undergraduate students of the University of Southern Santa Catarina - UNISUL, Pedra Branca, betweenAugust 2015 and July 2017.Materials and Methods: One hundred twenty-four patients with endodontic treatment were contacted. Ofthese, only 27 attended for treatment follow-up, adding up to a total of 32 treatments analyzed. All teeth wereclinically and radiographically evaluated, and the potential indicators related to endodontic treatment successor failure were analyzed. The frequencies of each criterion were calculated, and the data analyzed using theChi-Square test (α = 5%).Results: 9 cases (28.13%) were considered failure, either because they were associated with symptoms or becausethere was a periapical alteration. In addition, 88.88% of the failure cases had temporary restorative material.Association was observed only between the number of root canals and symptoms (P = 0.049). Two of the 3treated teeth with multiple root canals showed symptoms at the follow-up. The endodontic success rate was71.87%.Conclusion: The success rate of the 32 endodontic treatments performed by undergraduate students fromUNISUL was 71.87%

Frequência de lesão perapical pré tratamento endodontico em pacientes atendidos no curso de graduação em Odontologia da Universidade do Sul de Santa Catarina

Objective: To associate the frequency of periapical periodontitis previously to endodontic treatment with gender, age, canal numbers and dental position in patients treated by undergraduation students from UNISUL. Methods: Medical history and radiographs of all patients treated between August 2015 and December 2017 were assessed. Of a 2200 total records, 270 were included in this study. Data such as gender, age, tooth number, canal number and presence or absence of periapical periodontitis were collected. Descriptive analyzes and Fisher’s Exact Test was performed for association (statistical significance p≤0.05). Results: A total of 315 teeths were evaluated, of which 255 had periapical periodontitis, being 111 (55.5%) female gender and 44 (38.2%) were male (p=0.002). Regarding teeth group, 64.6% incisors presented periapical periodontitis, 29.5% canines and 41.1% premolars (p=0.000). Of these, 137 (53.7%) had only one root canal and 18 (30%) two or more (p=0.001). Also, concerning age range, from 18 and 29 years, 30 to 39, 40 to 49, 50 to 59 and 60 to 84 years, presented periapical periodontitis, respectively 42.3%, 50.0%, 50.0 %, 50.0% and 54.2% (p=0.333). Conclusion: The higher frequency of periapical lesion was influenced by gender, tooth position and root canal numbers.Objetivo: Associar a frequência de lesão periapical pré-tratamento endodôntico com o gênero, a faixa etária, número de canais e a localização dentária, de pacientes submetidos ao tratamento endodôntico pelos alunos de graduação da Unisul. Métodos: Foram avaliados os prontuários e as radiografias de todos os pacientes tratados entre o período de agosto de 2015 a dezembro de 2017. De um total de 2200 prontuários, 270 foram incluídos na pesquisa. Dados como gênero, idade, número do dente, número de canais e presença ou ausência de lesão periapical, verificada na radiografia inicial, foram coletados. Os resultados foram analisados segundo estatística descritiva e para associações, foi utilizado o Teste Exato de Fisher (significância estatística p≤0,05). O projeto foi aprovado pelo Comitê de ética da Unisul pelo Número do Parecer: 2.358.506. Resultados: Foram avaliados 315 dentes, dos quais 255 apresentavam lesão periapical, sendo 111(55,5%) de pacientes do sexo feminino e 44(38,2%) do sexo masculino (p=0,002). Com relação ao grupo de dentes, 64,6% dos incisivos apresentaram lesão periapical, 29,5% dos caninos e 41,1% dos pré-molares (p=0,000). E destes, 137(53,7%) apresentavam apenas um canal e 18(30%) dois canais, (p=0,001). E ainda, em relação a faixa etária, pacientes entre, 18 a 29 anos, 30 a 39, 40 a 49, 50 a 59 e 60 a 84 anos, apresentavam, lesão periapical respectivamente 42,3%, 50,0%, 50,0%, 50,0% e 54,2% (p= 0,343). Conclusão: A maior frequência de lesão periapical foi influenciada pelo gênero, posição do dente na arcada e número de canais
