In addition, World Health Organization aims for oral health, which consists on the maintenance of a natural dentition, functional and aesthetic composed of at least 20 teeth, without need of prosthetic intervention throughout life. From this and considering the lack of researches about the permanence of edentulous spaces in the oral cavity, and also avoiding overtreatment, this research has been proposed. Thus, the aim was to evaluate the effect of different lengths of the shortened lower dental arch in the presence or absence of a removable partial denture (RPD) on masticatory function, quality of life and occurrence of temporomandibular dysfunction. To achieve this goal, we compared the masticatory efficiency (colorimetric test), the oral comfort through the analysis of the impact of oral health in quality of life (OHIP-14), the presence of temporomandibular dysfunction (RDC/TMD) and the general quality of life (WHOQOL) of patients with shortened dental arches (SDA) (n=60), which is an arch with a reduction of teeth starting posteriorly, and patients with complete dental arch (Complete DA) (n = 34). The group of patients whit SDA was divided among PPR wears (PPD + SDA) (n = 17) and non-wears (n = 43). The population of this study consisted on patients who received or looked for treatment at the clinics of the Department of Dentistry of UFRN, from clinical analysis and records. The sample was chosen by convenience. For statistical analysis, it was a database in SPSS 17.0, followed by descriptive analysis with frequencies, absolute values, tests of central tendency and variability. The statistical tests used were chi-squared and analysis of variance as well as Tukey s post test, when applicable, all with a 95% confidence level. The results shown a prevalence of TMD of 47,1% among patients using PRP and 69,8% among those who didn t, but this result wasn t statistically significant. The mean of the results of masticatory efficiency, WHOQOL and OHIP didn t show association to the presence or absence of PPR and to the lower number of occlusal units of the patients (0, 1, 2 or more occlusal). The association only occurred among the different groups of SDA and the patients with complete dental arch. Taking into account the results, it could be observed that studied patients with low posterior support using lower PRP didn t have better masticatory efficiency, general quality of life, less impacts of their oral conditions in quality of life or not even less temporomandibular dysfunction or better masticatory efficiency when compared to those who didn t use the prosthesis / Existe ainda hoje no Brasil um grande n?mero de desdentados e uma prec?ria condi??o financeira da maior parte da popula??o. Al?m disso, existe uma meta preconizada pela Organiza??o Mundial de Sa?de para sa?de bucal, que consiste na manuten??o de uma denti??o natural, funcional e est?tica composta de, pelo menos, 20 dentes, sem que haja necessidade de uma interven??o prot?tica ao longo da vida. A partir disso e da escassez de estudos sobre a perman?ncia destes espa?os ed?ntulos na cavidade bucal e ainda, buscandose evitar sobretratamentos, esta pesquisa foi proposta. Desta forma, objetivou-se avaliar o efeito da varia??o do encurtamento do arco dental inferior na presen?a ou aus?ncia de pr?tese parcial remov?vel (PPR) sobre a fun??o mastigat?ria, qualidade de vida e presen?a ou n?o de disfun??o temporomandibular. Com este intuito comparou-se a efici?ncia mastigat?ria (teste colorim?trico), o conforto oral atrav?s do impacto das condi??es bucais na qualidade de vida (OHIP-14), a presen?a de disfun??o temporomandibular (RDC/TMD) e qualidade de vida geral (WHOQOL) de pacientes com arco dental curto (ADC) (n=60), ou seja suporte posterior reduzido e ainda a um grupo de indiv?duos com arco dental completo (AD Completo) (n = 34). O grupo de pacientes que apresentava ADC foi subdividido entre usu?rios de PPR (ADC +PPR) (n=17) e n?o usu?rios (n=43). A popula??o foi constitu?da por pacientes que recebem tratamento nas cl?nicas do Departamento de Odontologia da UFRN ou que est?o em busca do mesmo, a partir de an?lise de prontu?rios e triagem pr?via. A amostra foi por conveni?ncia. Para a an?lise estat?stica, fez-se um banco de dados no SPSS 17.0, seguida da an?lise descritiva com freq??ncias, valores absolutos, testes de medidas de tend?ncia central e variabilidade. Os testes estat?sticos utilizados foram o qui quadrado e an?lise de vari?ncia seguido do p?s teste de Tukey quando aplic?vel, tudo com n?vel de confian?a de 95%. Com os resultados observou-se que a preval?ncia de DTM foi de 47,1% entre os pacientes que utilizavam PPR e 69,8% entre os que n?o utilizavam, mas isto n?o foi estatisticamente significante. Quanto ?s m?dias dos resultados da efici?ncia mastigat?ria, WHOQOL e OHIP n?o houve associa??o com a presen?a ou aus?ncia de PPR inferior e nem com o n?mero de unidades oclusais dos pacientes (0, 1, 2 ou mais unidades oclusais). A associa??o s? ocorreu entre o grupo AD Completo e os subgrupos de ADC. Levando-se em considera??o os resultados pode-se observar que pacientes com suporte posterior bastante reduzido que utilizam PPR inferior n?o possuem melhor efici?ncia mastigat?ria, qualidade de vida geral, nem as condi??es bucais impactam menos na sua qualidade de vida, nem apresentam menos DTM e nem possuem uma melhor efici?ncia mastigat?ria quando compar?veis aos pacientes que n?o utilizam PPR com as mesmas condi??es bucais
