Enamel defects in teeth adjacent to missing primary canines, as observed in the current study, are a later consequence of canine bud removal, and increase the risk for caries, sensitivity and tooth breakdown [ 16].
A long cone "paralleling technique" [ 9], with a standardized receptor holder [ 10], is recommended for obtaining the radiographs, and it has been suggested that the direct method (in mm) should be used when investigating the susceptibility of different teeth to periodontal breakdown in clinical trials of comparative nature [ 10, 11].
The thesis looked at the histopathology of the dental pulp of 79 primary molar teeth with marginal ridge breakdown (MRBD).
Periodontitis, an almost ubiquitous disorder in the adult population, induces the breakdown of tooth-supporting apparatus which, unfortunately, has an extremely limited capacity for self-repair and regeneration.
The posterior teeth had more post-eruptive breakdown and hypoplasia than anterior teeth in agreement with other studies.
Affected teeth occasionally undergo post-eruptive breakdown due to soft and porous enamel, resulting in atypical cavities or even to complete coronal distortion [ 3].
Here, we show that in periodontitis progression there are certain characteristic activities that are associated with the onset of breakdown in specific teeth.
It is unclear whether the apparent loss of enamel from these teeth results from post-eruptive breakdown or whether this is a primary developmental defect.
This is followed by heavy traffic, possibly a breakdown, map anxiety, tooth-tasering sweets and, the coup de grâce, a full marital row… Sadly this month, the car that accompanied us on our long haul up to Scotland was far too well behaved, and we all arrived north of the border still on speaking terms.
Periodontal diseases cause the breakdown of the tooth-supporting gingival tissue.
