This retrospective study used CBCT to quantify the number of missed canals during previous endodontic treatment in maxillary first and second molars needing retreatment. The second mesiobuccal canal was missed most frequently (incidence = 49.38%). To lower the risk that canals will be missed, clinicians should consider the use of CBCT for maxillary molars before endodontic treatment.

Chanika Manmontri
About 49 months after partial pulpotomy of the mandibular right first molar in a 10-year-old boy, the tooth was diagnosed with irreversible pulpitis and asymptomatic apical periodontitis but responded positively to cold testing, and the pulp appeared clinically vital on direct inspection. Coronal pulpotomy was performed to maintain vitality in the young tooth, and successful resolution of the periapical lesion was observed 21 months later.

Performance of a novel self-adhesive bulk-fill composite hybrid in endodontically treated maxillary premolars: analysis of fracture resistance and failure mode
Fereshteh Shafiei
Shadi Tivay
Zahra Fattah
This in vitro study assessed the effect of different application protocols on the fracture resistance of a self-adhesive composite hybrid material (Surefil one [SO]) in endodontically treated teeth. The use of SO with a capping layer of conventional composite provided the highest fracture resistance values but also the highest rate of unrestorable fractures. Self-cured SO showed similar fracture resistance but a higher rate of restorable fractures.

Otodental syndrome is a rare combination of hearing loss and the presence of abnormal, globe-shaped teeth, usually the molars or canines. This report describes the case of a 12-year-old boy who had hearing loss and 2 supernumerary globe-shaped teeth in the sites of the permanent maxillary central incisors, an unusual location. Both anomalous teeth were extracted, allowing spontaneous eruption of the impacted permanent central incisors.

Evaluation of artifacts produced by conventional dental materials in standard and high-resolution CBCT imaging

Mitra Ghazizadeh Ahsaie
Zahra Sahebnasagh
This study assessed the artifacts produced by common dental materials in CBCT images at standard and high resolutions. Only one material, a root canal sealer, showed a statistically significant reduction of artifacts at high resolution compared to standard resolution. For most materials, high resolution resulted in more artifacts, suggesting that standard resolution can be used in most CBCT examinations to reduce the radiation exposure of patients.

Psychosocial Anxiety and Fear in Dentistry
The effects of a therapy dog intervention on dental fear and anxiety in adult patients undergoing dental procedures: a pilot study

This pilot study assessed the effectiveness of therapy dogs in alleviating dental fear and anxiety. There were no significant differences in heart rate variability during dental procedures between patients who interacted with dogs prior to procedures and those who did not, but patients in the dog therapy group expressed high levels of satisfaction with the intervention, suggesting that therapy dogs can effectively manage dental anxiety in adults with mild to moderate dental anxiety.

Clinical guidelines for posterior semidirect composite resin restorations: a case report with a 17-month follow-up
Franco Naoki Mezarina-Kanashiro
Fernanda Furuse Ventura dos Santos
Adilson Yoshio Furuse
The aims of this case report were to describe the extraoral semidirect restoration, a viable alternative to direct and indirect restorations for posterior teeth with extensive decay, and highlight its indications, advantages, and disadvantages. The semidirect procedure consists of tooth preparation for an indirect restoration, an alginate impression, restoration fabrication on a flexible cast, cementation, removal of excess cement, and occlusal adjustment.

Anna Pitz
Peter C. Moon
Caroline K. Carrico
This study investigated different surface treatment and adhesive agents to determine the most effective method for bonding composite resin to amalgam. Silicoated specimens had significantly higher mean bond strengths than specimens prepared with 2 different air particle abrasion protocols, and there were no differences in bond strengths among the adhesive subgroups in the silicoated group.

Ectopic sulcular pain: detection and treatment
James V. Potter
This case series is presented to propose and define a new term, ectopic sulcular pain, for a common condition in which patients experience acute or chronic posterior sulcular pain for which no physical cause can be identified. Ectopic sulcular pain presents with confusing symptoms that are common across a range of conditions, but this report offers diagnostic steps and a treatment protocol.

This pilot study was conducted to provide data for a future randomized control trial of a line of oral hygiene products containing a prebiotic and a paraprobiotic. Toothpastes, mouthwash, and a custom toothbrush were tested by 4 treatment groups, while a control group used their normal oral hygiene products. No between-group analyses of effectiveness were conducted, but all treatment groups showed significant decreases in plaque and gingival sensitivity after 28 days of use.

This article summarizes the history, development, and use of ChatGPT in dentistry. Areas of use include telemedicine, clinical decision-making, patient support, education, writing, and research. However, use of ChatGPT raises ethical and privacy concerns, and its imperfect accuracy means that the information it provides must be independently verified. ChatGPT can play a supportive role in dentistry, but it can never replace the judgment of dental professionals or students.
