Abstract: A inflamação periapical resulta da invasão da cavidade polpar por bactérias orais (na sequência de trauma, desgaste severo ou cárie dentária). Diferentes lesões periapicais (granuloma, quisto, abcesso, osteomielite) têm repercussões diversas, desde desconforto durante a mordida até efeitos sistémicos graves. O objetivo deste estudo consiste em avaliar a frequência dos diversos tipos de lesões periapicais numa amostra de esqueletos da necrópole medieval (séculos XII-XVI) de São João de Almedina (Coimbra, Portugal) de modo a inferir o seu impacto na qualidade de vida dos indivíduos. Observaram-se macroscopicamente 1040 alvéolos de 54 indivíduos adultos (26 masculinos, 16 femininos, 12 de sexo indeterminado). O diagnóstico diferencial das lesões foi efetuado seguindo Dias e Tayles (1997) e Hillson (2001). Foram observadas lesões periapicais em 31,5% dos indivíduos e 3,2% dos alvéolos. Das 33 lesões registadas, 29 eram granulomas ou quistos e quatro eram lesões residuais. As lesões foram observadas mais frequentemente no sexo masculino (38,5%, 9/26) do que no feminino (31,3%, 5/16). O principal fator causador das lesões foi a cárie. Atendendo a que apenas foram identificadas lesões relativamente benignas e assintomáticas, conclui-se que a inflamação periapical não terá tido um impacto muito negativo nos indivíduos estudados. Periapical inflammation results from tooth pulp invasion by bacteria following trauma, severe wear, or dental caries. Considering the different repercussions that the various periapical lesions present, the objective of this study is to evaluate their frequency in a skeletal sample from the medieval necropolis (12th−16th centuries) of São João de Almedina (Coimbra, Portugal). In all, 1007 alveoli, belonging to 54 adult individuals (26 males, 16 females, and 12 individuals of unknown sex), were macroscopically examined. The differential diagnosis of the lesions was performed following Dias and Tayles (1997) and Hillson (2001). Periapical lesions were observed in 31.5% of the individuals, and 3.2% of the alveoli. Of the 33 lesions, 29 (87.9%) were granulomas/cysts and four (12.1%) were undergoing remodelling. No abscesses or osteomyelitis were observed. No differences in the lesions’ distribution by sex, age group or laterality were found. Both anterior and upper alveoli revealed more lesions, probably due to lower bone density or greater post-mortem tooth loss. Granulomas/cysts were mainly found without any opening. The main aetiological factor identified was caries. Considering that only relatively benign and asymptomatic lesions were identified, periapical inflammation would not have had a very negative impact on the individuals studied.
