“…Cracks in teeth were identi ed visually through the utilization of a 6x magnifying loupe, coupled with transillumination employing an LED light source directed perpendicular to the tooth [33]. This method facilitated the detection of cracks by observing the diffraction of light when it intersected the crack, thereby enabling the precise localization of the crack and the exclusion of affected specimens [34]. Following these assessments, the teeth were subjected to a thorough ultrasonic cleaning procedure.…”

Background: The rising demand for improved aesthetics has driven the utilization of recently introduced aesthetic materials for creating custom post and core restorations. However, information regarding the fracture resistance of these materials remains unclear, which limits their practical use as custom post and core restorations in clinical applications. Aim of the study: This study aimed to evaluate the fracture resistance of three non-metallic esthetic post and core restorations and their modes of failure. Materials and Methods: Thirty-nine single-rooted human maxillary central incisors were endodontically treated. A standardized post space preparation of 9mm length was performed to all teeth to receive custom-made post and core restorations. The prepared teeth were randomly allocated to receive a post and core restoration made of one of the following materials (n=13): glass fiber-reinforced composite (FRC), polyetheretherketone (PEEK) and polymer-infiltrated ceramic-network (PICN). An intraoral scanner was used to scan all teeth including the post spaces. Computer-aided design and computer-aided manufacturing (CAD-CAM) was used to fabricate post and core restorations. Post and core restorations were cemented using self-adhesive resin cement. All specimens were subjected to fracture resistance testing using a universal testing machine. Failure mode analysis was assessed using a stereomicroscope and SEM. The data was statistically analyzed using One-Way ANOVA test followed by multiple pairwise comparisons using Bonferroni adjusted significance level. Results: Custom PEEK post and core restorations displayed the least fracture load values at 286.16 ± 67.09 N. In contrast, FRC exhibited the highest average fracture load at 452.60 ± 105.90 N, closely followed by PICN at 426.76 ± 77.99 N. In terms of failure modes, 46.2% of specimens with PICN were deemed non-restorable, while for PEEK and FRC, these percentages were 58.8% and 61.5%, respectively. Conclusions: Within the limitation of this study, both FRC and PICN demonstrated good performance regarding fracture resistance, surpassing that of PEEK.

“…Early carious lesions are characterized by mineral loss beneath the tooth surface, leaving the outermost layer intact but weakened [21][22][23]. Additionally, cracked teeth contain fine fissures that penetrate the enamel or dentin [24,25]. Therefore, applying excessive pressure or high-speed during rubber cup polishing can cause irreversible damage to these areas.…”

High-speed rubber cup polishing can exacerbate tooth surface damage, especially when preexisting conditions such as early caries or cracks exist. This study aimed to quantify the extent of damage to sound teeth based on rotating rubber cup speed and assess the damage in relation to the tooth surface condition. Using a rubber cup, 36 sound teeth were polished at 100, 3000, and 10,000 rpm, and 24 teeth with early carious lesions and 24 cracked teeth were polished at 3000 and 10,000 rpm. Polishing was performed using a rubber cup and prophylaxis paste, applying an on–off method (3.0 N force for 3 s). Damage depth was quantified using a surface profilometer and examined using scanning electron microscopy. Polishing at 10,000 rpm caused significantly more damage to sound teeth than polishing at lower speeds (depth increase: 71.45 ± 15.12 µm at 100 rpm; 61.91 ± 17.82 µm at 3000 rpm; p < 0.001). Teeth with early carious lesions or cracks demonstrated more damage after polishing than sound teeth (p < 0.05). Therefore, the rotational speed of the rubber cup has a critical impact on the extent of enamel damage. Higher speeds can increase the damage depth in both sound and damaged tooth surfaces.

“…The deeper the fissure, the greater the inflammatory reaction [10] . Subgingival fissures give rise to narrow and isolated periodontal pockets that can favor bacterial invasion and lead to tooth loss [11] . It is important that the clinical characteristics of cracked teeth are known by the health professional and can differentiate the discomfort that the patient experiences when chewing, Since the pain provoked when the patient stops biting is a characteristic diagnostic difference.…”

Introduction: Cracked teeth is one of the most common cause of tooth loss in developed countries. Objective: To analyze the literature on cracked teeth, mainly its etiology, diagnosis, prevalence and treatment. Methodology: A compilation was made of articles published in the last 5 years using the electronic database PubMed, Scopus and Google Scholar. Abstracts and full texts were identified that included information on cracked teeth: "cracked", "teeth", "etiology", "diagnosis", "prevalence" and "treatment". Results: Having knowledge of the etiology allows the dentist to detect it in time, thus avoiding the propagation of cracks and complications associated with it. Early diagnosis can be a simple restoration, if it progresses it is often necessary to treat the root canal and restore the cusp coverage. The number of cases has increased due to the lack of information for early diagnosis. The treatment of the affected tooth and its prognosis is generally difficult to determine. It depends more on the location, extent and magnitude of the damage caused by the fissure when diagnosed and the time of treatment. Conclusion: Cracked teeth is one of the main causes of extractions. The use of conventional radiographs does not allow us to make an adequate diagnosis. There is a high prevalence of this problem in older adults, since most of the teeth are treated in some way, and the treatment of a cracked tooth depends on the complexity of the case.
