Cervical margin relocation (CMR), also known as deep margin elevation, is a minimally invasive restorative technique used to reposition subgingival margins to a supragingival level. Subgingival margins, extending below the cemento-enamel junction (CEJ) present significant biological risk...

Molar incisor hypomineralization (MIH) is a qualitative enamel defect characterized by reduced mineralization, increased porosity, and compromised mechanical properties, making affected teeth highly susceptible to posteruptive breakdown, hypersensitivity, and restorative failure. Conventional direct restorations often exhibit limited longevity in severely affected molars due to weak enamel bonding and structural fragility. Consequently, indirect restorations with cuspal coverage have been increasingly recommended as a more durable and protective treatment option. This clinical case reports the restorative management of MIH‐affected maxillary first molars in a 24‐year‐old patient using lithium disilicate ceramic overlays. Following the removal of defective amalgam restorations, a minimally invasive tooth preparation with a butt‐joint design was performed, combined with immediate dentin sealing to enhance adhesion. Impressions were taken using polyvinylsiloxane materials, and overlays were fabricated via CAD/CAM technology. Adhesive cementation was carried out under strict isolation, including surface treatment of both the restoration and dental tissues. The use of lithium disilicate overlays provided a conservative yet effective approach, ensuring reinforcement of weakened tooth structure while preserving remaining sound tissues. The literature supports the high survival rates of such restorations in MIH cases, with reduced hypersensitivity and satisfactory functional and aesthetic outcomes. In conclusion, lithium disilicate overlays represent a reliable and minimally invasive solution for the rehabilitation of compromised MIH molars. Careful case selection, proper adhesive protocols, and regular follow‐up are essential to ensure long‐term success, particularly given the inherent fragility of MIH‐affected enamel.

Corono-Radicular Restoration Using Fragment Bonding: An Esthetic Option for Managing Fractured Lateral Incisor

Many orthodontic clinics have problems with patients who have dental demineralization. This study aimed to evaluate “the shear bond strength (SBS)” of braces after being bonded to demineralized teeth treated with herbal materials. Our study samples were divided into five groups. The first group was left with no treatment. The surfaces of the second, third, and fourth groups were first treated with a demineralizing solution. The second group was left after being demineralized without any subsequent treatment; the third group was treated with rosemary oil; the fourth was treated with ginger–honey. Casein phosphopeptide–amorphous calcium phosphate with fluoride paste (CPP–ACPF) was applied to the fifth group. A universal testing machine evaluated the SBS. A stereomicroscope was used to determine the adhesive remnant index (ARI). The enamel surface changes were observed using surface microhardness (SMH) testing, scanning electron microscopy (SEM), and energy dispersive spectrometry (EDS) to determine the element percentages. Our data revealed that the values of both SBS and SMH were significantly (p < 0.05) increased after remineralization. Rosemary and ginger–honey significantly enhanced the SBS and SMH of the demineralized teeth.

Lateral luxation is defined as a traumatic displacement of a tooth in any direction other than axially. A laterally luxated tooth is often immobile because of its bony lock. It produces a high metallic sound during percussion. Pulp sensibility testing is likely to be negative during the initial follow‐up. However, the tooth should be monitored until a definitive pulp diagnosis is made. Treatment includes local anesthesia, suturing soft tissue injuries, manual repositioning of the luxated tooth, and stabilization with a flexible splint for 4 weeks. Given the risk of pulp necrosis following lateral luxation, particularly in teeth with radiographically closed apices and severe displacement, an immediate (prophylactic) root canal treatment is recommended. The objective of this work was to report and discuss the management of a case of lateral luxation involving a permanent tooth treated by reduction, followed by contention with 0.4 steel wire and composite resin, and endodontic treatment, and which was complicated by root resorption 3 months later. We also highlighted the possible complications following lateral luxation, especially root resorption.

Ossification of stylohyoid chain corresponds to the ossification of stylohyoid ligament that can vary from thin short to thick long ossification and can be associated with other calcifications. We report in this case a bilateral non painful complete ossification of the stylohyoid complex extended to the thyrohyoidien ligament.
