“…A more detailed analysis revealed that 52.1% of vertical and 42.9% of oblique cracks predisposed to higher risk of greater extent tooth damage following the removal of brackets. Previous investigations have demonstrated that horizontal micro-cracks possessed high risk of underlying pathology 21) . Thus, it was surprising to see that in our study horizontal cracks were related with low possibility of higher amount enamel defects.…”

The objective of this in vitro study was to evaluate the effect of the enamel cracks on the tooth damage during the debonding. Measurements of the cracks characteristics (visibility, direction, length, and location) were performed utilizing a scanning electron microscopy (SEM) technique and mathematically derived formulas (x=h/30, l=n*x) before and following the removal of mechanically retained metal and ceramic brackets. The likelihood of having greater extent enamel defects was higher for the teeth with pronounced cracks (odds vatios, OR=3.728), increased when the crack was located in more than one zone of the tooth (OR=1.998), and the inclination did not exceed 30-45° (OR=0.505). Using ceramic brackets the risk of greater amount tooth structure defects raised 1.45 times (OR=1.450). Enamel crack showing all these characteristics at the beginning of the orthodontic treatment and the use of ceramic brackets might predispose to higher risk of greater extent tooth surface damage after the debonding by 20.4%.

“…Several studies showed that bleaching methods using only peroxides without light sources can cause tooth sensitivity, and this can be due to the used peroxide or one of the other ingredients in the bleaching gel [12][13][14][15][16]. On the other hand, it has been estimated that the incidence of tooth fractures or tooth cracks is to be 5 per 100 adults per year [17][18][19][20]. In fact, enamel surface cracks or craze lines, are relatively common in adult teeth [17][18][19][20].…”

Bleaching induced tooth sensitivity: do the existing enamel craze lines increase sensitivity? A clinical study

The aim of this clinical study was to evaluate whether or not an association exists between the presence of enamel craze lines and the prevalence of tooth sensitivity (TS) after in-office bleaching. Subjects that met the inclusion criteria (N = 23) were screened to detect the existence of enamel craze lines. In total, 460 teeth were subjected to bleaching where 49% of them presented enamel craze lines. After bleaching (15% hydrogen peroxide), the subjects were asked to rate the level of TS by answering a self-administered questionnaire. The majority of subjects (91%) experienced TS at the first day of bleaching. The TS prevalence decreased gradually to 22% at second day, to 17% at third day, and to 9% at fourth day. After the fourth day, no subject reported TS. While 15% of teeth with craze lines presented TS, 11% of teeth with no craze lines also showed TS. A positive but weak correlation (r = 0.214) was found between the existence of enamel craze lines and TS. In this clinical study, higher incidence of TS was found with the use of 15% hydrogen peroxide bleaching agent compared to the previous studies. Patients who would undergo in-office bleaching should be informed that tooth sensitivity is a very often side effect but it may disappear within 1 week.
