Intra-alveolar root @entity174 of posterior teeth are rare when compared with other @entity8495 . This case report describes one vertical and two horizontal root @entity174 of teeth 3, 14, and 15. The teeth all tested normal to cold and electric pulp tests. The @entity1 reported no history of accidental @entity130 , and no signs of @entity2318 were found. These @entity174 were discovered during a routine full-mouth radiographic survey. All teeth were asymptomatic and in good function. During the 11 yr that followed, there was no dental treatment, except for routine periodontal maintenance. The @entity1 had one abscess that occurred after 9 yr on tooth 3, which had to be extracted. The upper left molars are surprisingly still in function and asymptomatic. Either occlusal or lateral @entity130 may be the cause of these @entity174 . This would strongly suggest night guard appliances for @entity1 who clench or grind. A psychological evaluation of the @entity1 might reveal @entity11167 , @entity148 , or stress situations affecting teeth.
