“…Many studies showed that defects in cementum or loss of cementum resulting in dentinal exposure would act as a contributing factor to pulpal inflammation and progression towards the need for a root canal treatment. Defects in cementum can arise during root surface debridement or can occur naturally as variations in the relationship between enamel and cementum at the cementoenamel junction [ 25 , 26 ]. An increase in the amount of bone loss does not necessarily lead to more non-vital teeth, which was confirmed in this study as there was no significant statistical relationship between the degree of bone loss and the percentage of teeth with RCT.…”

The aim of this study was to determine whether the degree of bone loss around teeth can be linked to the loss of vitality of adjacent teeth and periapical disease, which necessitates root canal treatments. Three hundred and twenty-one full maxilla cone-beam computed tomography scans were examined. The parameters investigated included the degree of crestal bone loss in relation to the cementoenamel junction, the presence/absence of apical periodontitis, and the presence/absence of root canal treatments. Out of the 2001 teeth examined, 696 (34.8%) showed evidence of crestal bone loss. The degree of crestal bone loss was classified as mild, moderate, or severe. A significant association (p < 0.001) was found between the presence of crestal bone loss around a tooth and root canal treatment of that tooth. It was found that it is more likely for teeth with crestal bone loss to be root canal treated compared to teeth with existing root canal treatment and healthy crestal bone levels. Furthermore, teeth with buccal or lingual crestal bone loss were significantly associated with a higher rate of periapical disease than teeth without crestal bone loss (p < 0.001). CBCT identified the severity of bone loss on all surfaces of the teeth, and the most common presentation was bone loss to the mid-root level. Teeth with crestal bone loss were significantly more likely to be associated with a higher rate of periapical disease. Teeth with crestal bone loss were more likely to be root treated than teeth with healthy crestal bone levels.

“…Likewise, OM allows evaluating only 2 points of the CEJ of each sample, a fact that would allow greater errors of interpretation by generating optical illusions due to the thickness of the sections. 4,7,14,16,19 On the other hand, since there are studies that link the type of CEJ with the type of tooth and tooth sector, 14,16,25 it may be possible that, when studies are performed on teeth of different types, the results show great variability. However, some authors have concluded that, regardless of the type of method used, the type of CEJ of a tooth is unpredictable.…”

Morphology of the Cementoenamel Junction in Permanent Teeth of Dogs: A Scanning Electron Microscopic Study

In human teeth, the cementoenamel junction (CEJ) can have different morphologies, known as Choquet cases or types: in type 1, the cementum overlaps the enamel; in type 2, the enamel overlaps the cementum; in type 3, the relationship between the cementum and enamel is edge-to-edge; and in type 4, there is a gap between the enamel and the cementum, with exposed dentin. Since little is known on the morphology of the CEJ in animals, the aim of this study was to characterize the structure of the CEJ of dog teeth by SEM. We studied 82 permanent teeth extracted from 4 dogs of similar size, aged from 7 months to 2 years. Teeth were grouped according to their size, sectioned and prepared for SEM. The teeth evaluated showed the 4 CEJ types. Type 3 was the most prevalent, being present, either alone or in combination, in 90.79% of the samples, followed by type 4 (present in 31.58% of the samples). Of the samples, 65.13% showed only one type, while 34.87% presented a combination of them. Types 3 and 4 were the only ones present alone (in 55.92% and 9.21% of the samples respectively), whereas the combinations between types 3 and 4 (20.40%) and types 1 and 3 (9.87%) were the most frequent. In all combinations, type 3 was predominant. The CEJ of the dogs evaluated showed a high degree of variability in the different types of teeth, within a same tooth, within the dentition of a single individual, and among individuals.

“…Roa et al (5) reported the four relationships between the cement and enamel that was described by Choquet in a sample of 68 teeth (9). In their findings, 51.9% of the cases described the relationship when the cement and enamel were in contact, whereas 42.4% of the cases showed that the enamel overlapped the cement.…”

ACTA FACULTATIS MEDICAE NAISSENSIS UDC: 616.314 SU M M A RYCemento-enamel junction (CEJ) is an important anatomical structure of the tooth, which is located in the cervical part of the tooth between the crown and root, or at the contact point between the enamel which overlaps the tooth crown and cementum overlapping the root dentin.There are four possible relationships between two tissues that make the CEJ such as: the cement overlaps the enamel; the enamel overlaps the cement; the enamel and cement abut each other with no overlap; the enamel and cement are not in contact. The aim of this study was to determine the relationship between the enamel and cement which make the CEJ in different types of permanent teeth.The material consisted of 30 permanent teeth with intact CEJ. Staining of CEJ was carried out using the methylene blue. After staining, the tooth was washed under the running water and drying at room temperature. Each tooth was longitudinally cut in the vestibular-oral direction. Observation of CEJ was done with Leica light microscope and images were obtained using a Nikon camera.The results indicated that the most common form of CEJ between the cement and enamel in the region of CEJ was that cement and enamel abutted without overlap (36.7%), followed by the cement overlapping the enamel (33.3%), and the cases when a gap between the cement and enamel (16.7%) was present, and when the enamel overlaped the cement (13.3%).Because of the morphological diversity of CEJ, careful performing of dental interventions in the region of tooth neck is necessary because they may change the morphology of this region, induce the pathological processes and hypersensitivity of teeth.
