AI Article Synopsis
- The study examined the effects of a zinc oxide/zinc sulfate-based cement (Coltosol® F) on cracks in filling material and teeth during root canal treatment.
- The research involved 122 human molars, which were divided into four groups with different filling techniques, and monitored for cracks over 14 days.
- Results showed that all teeth with Coltosol® F exhibited cracks, with 76% experiencing tooth fractures, particularly vertical root-crown fractures, highlighting its potential risks in dental procedures.
Article Abstract
Objectives: To investigate the effect of a zinc oxide/zinc sulphate-based cement as a temporary filling material during root canal treatment on the occurrence of cracks within the filling material or the tooth.
Materials And Methods: Root canals of 122 extracted human molars were prepared using ProTaper instruments. Standardized occlusal-distal cavities were prepared. After placing calcium hydroxide into the root canals, the teeth were divided randomly into four groups containing 33 specimens each. In the Coltosol group, the cavity was completely filled with Coltosol® F. In the Coltosol-Clearfil group, a 2-mm layer of Coltosol® F was placed into the apical part of the pulp chamber, and in the Clearfil group, a foam pellet was placed into the coronal pulp chamber. The remaining cavities were filled with Clearfil™. In the control group, the cavities were not restored. The teeth were stored at 37 °C for 14 days and examined every 24 h under a stereomicroscope.
Results: Fractures of the filling and/or the tooth were only observed in the Coltosol group. All Coltosol® F restorations had cracks after 24 h. Tooth fractures were found in 25 (76 %) teeth. Among these teeth, 21 (84 %) had crown fractures, four (16 %) had root-crown fractures. All root-crown fractures were vertical.
Conclusion: Coltosol® F when used alone led to tooth fractures in two-surface class II cavities in teeth undergoing root canal treatment.
Clinical Relevance: Coltosol® F solely used as restorative material may lead to tooth fractures in two-surface class II cavities.

Rigid maxillomandibular fixation using a novel technique involving unbonded polymethylmethacrylate canine tooth moulds and interarch wiring for maxillomandibular trauma in three cats.

Mandibular and maxillary fractures are common in small animals and present significant challenges for repair due to the intricate anatomical features involved. This retrospective case series describes a technique for achieving rigid open mouth maxillomandibular fixation using interarch wiring while maintaining correct alignment between the upper and lower teeth with polymethylmethacrylate (PMMA) moulds of the canine teeth for treating maxillomandibular fractures in cats. The study includes a description of the postoperative outcomes and complications encountered.

Purpose: To investigate how varying ferrule heights and the number of glass fiber posts affect fracture resistance and behavior of endodontically treated maxillary first premolars with substantial loss of tooth structure.
Materials And Methods: Twenty-four extracted endodontically treated human maxillary first premolars were divided into three groups (n = 8) based on ferrule height and post number. The groups were as follows: premolars of 2 mm ferrule height that were restored with single posts (control group), premolars of 0.

This study aimed to evaluate the effects of fiberglass posts on fracture behavior in endodontically treated teeth (ETT) restored with composite veneers. Adult patients who had endodontically treated anterior teeth restored with composite veneers, with or without fiberglass posts, were divided into the case (with fractured teeth) and control (without fractured teeth) groups. All fracture patterns were sorted by a 6-point scoring system: 0, no fracture; 1, veneer buccal fracture; 2, incisal edge fracture; 3, coronal middle-third fracture; 4, coronal cervical fracture; 5, coronal and root fracture; and 6, root fracture.

Objectives: To compare the stress distribution and crack propagation in cracked mandibular first molar restored with onlay, overlay, and two types of occlusal veneers using two different CAD/CAM materials by Finite Element Analysis (FEA).
Materials And Methods: A mandibular first molar was digitized using a micro CT scanning system in 2023. Three-dimensional dynamic scan data were transformed, and a 3D model of a cracked tooth was generated.

Osteoporosis is a systemic disease associated with reduced bone mass, impaired bone microarchitecture, and thus an increased risk of bone fractures. Moreover, patients with osteoporosis are more likely to experience periodontal diseases and tooth loss. Some indices have been proposed to detect osteoporosis on dental panoramic radiographs.
