Intra-alveolar root fractures of posterior teeth are rare when compared with other dental injuries. This case report describes one vertical and two horizontal root fractures of teeth 3, 14, and 15. The teeth all tested normal to cold and electric pulp tests. The patient reported no history of accidental trauma, and no signs of scarring were found. These fractures 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 patient 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 trauma may be the cause of these fractures. This would strongly suggest night guard appliances for patients who clench or grind. A psychological evaluation of the patient might reveal neurosis, anxiety, or stress situations affecting teeth.
Rett syndrome is a unique and puzzling disorder noted in females and is possibly caused by fundamental failures in critical brain connectivity during early infancy. The most frequent habits in Rett syndrome are hand sucking or biting, bruxism and mouth breathing. Children with musculoskeletal disorders and children who suffer from mental retardation commonly grind their teeth. A five year old female case with Rett syndrome is presented with significant bruxism in this article.
