Abstract
Tooth infraction is usually of three types 1) confined to enamel (craze lines) and usually do not require treatment 2) related to cuspal fracture that typically do not involve pulp 3) more centrally located that do involve the pulp. Vertical root fracture (VRF) are longitudinal fracture that originate in root of teeth in contrast to tooth infraction that originate in the crown. VRF occurs usually in endodontically treated teeth. This case report represent tooth infraction originating in the tooth crown on the distal marginal ridge and propagating into the pulp chamber and DEJ(dentino enamel junction). Root canal treatment was performed and in a 7 month follow up period, there was a remarkable improvement in the supporting periodontal structures with bone deposition/remodelling in the crestal and furcation area/region and patient was quite satisfied with the treatment outcome.
Highlights
Tooth infraction is usually of three fairly distinct types 1) confined to enamel and usually do not require treatment 2) related to cuspal fracture that typically do not involve pulp and 3) more centrally located that do involve the pulp
Tooth infraction do occur due to the result of accumulating unobserved trauma from either normal or excessive occlusal forces that are repetitively applied without patient’s awareness[2] Usually treatment of cracked teeth takes five to ten years Krell et al but in our study since the crack was diagnosed early enough duration took around six to seven months with minimal treatment expenditure which is similar to studies by Minocha et al 5 Based on the study done by Hassan et al 6 an exploratory exacavation was done to obtain visual diagnosis
Later IOPA radiographs were taken diagnosis of cracked tooth syndrome by radiographs is usually questionable, as fractures propagate in a mesiodistal direction; parallel to the plane of the film
Summary
Tooth infraction is usually of three fairly distinct types 1) confined to enamel (craze lines) and usually do not require treatment 2) related to cuspal fracture that typically do not involve pulp and 3) more centrally located that do involve the pulp. Symptomatic tooth infractions are confusing because they often mimic symptoms of other conditions such as earache, sinusitis, temperomandibular joint dysfunction, and other neurological pain conditions like trigeminal neuralgia. 1 When the problem is difficult to identify, it can lead to a long standing pain condition that becomes more diffuse and makes localization of the offending tooth very difficult.[2] The act of chewing is implicated in the development of infraction. Visual examination with the use of transillumination and methylene blue dye is required for examination of disease. As for all treatment efforts are attempts- some better than others- at preventing separation of the hard tissues entities, and perhaps keeping bacteria from colonizing the space caused by infractions
