This study tested a jaw support device for patients receiving dental care while suffering from temporomandibular joint pain. Statistically significant differences were found for jaw pain (P = 0.001), and fatigue (P = 0.04), indicating the effectiveness of the device. The study found that supporting the mandible of patients with temporomandibular disorders during dental treatments may prevent further pain.

The aim of this study was twofold: determine whether bubble formation in alginate is influenced by the sequence of water/powder addition prior to mixing, and to compare 4 different spatulation techniques. Porosity was significantly less for powder-first trials using manual spatulation (P < 0.05) but the sequence made no difference with the other techniques (P = 0.714). Surface porosity was significantly less for centrifugal and vacuum mixing compared to manual spatulation, while internal porosity was significantly less for centrifugal mixing compared to all the other techniques (P < 0.05).

This study sought to measure the microtensile bond strength of a nanofilled composite resin to human dentin after phosphoric acid etching followed by nonvital bleaching. Twenty extracted human maxillary premolars were prepared and assigned randomly to 4 groups (n = 5): Group 1 (control) – unbleached with no previous acid etching, Group 2 – bleached only, Group 3 – acid-etched for 15 seconds prior to bleaching, and Group 4 – acid-etched for 30 seconds prior to bleaching. There were no statistically significant differences of bond strength values among Groups 1-3; however, the mean values of Group 4 were statistically lower compared with the other groups.

It is important for every dentist to be aware of the maxillofacial manifestations of multiple myeloma (MM), especially with regard to early diagnosis, since injury can occur when MM is in its primary form in the maxillary bones. This case report presents a 58-year old man with mandibular swelling; his medical history indicated he had a fracture of the humerus a month earlier. The patient underwent chemotherapy for the MM, and a hemimandibulectomy was followed by the installation of a reconstructive plate for the fractured jaw.

This case report identifies a side effect of vitreoretinal surgery with a benign outcome—specifically, a referred pain or pressure from left eye surgery or an associated gas bubble to the upper left quadrant. Such cases underscore the need for a dentist and staff to inquire about all ocular procedures to avoid catastrophic patient vision loss due to nitrous oxide, which is absolutely contraindicated after vitreoretinal surgery that uses intraocular gas. Dentists should communicate with the patient’s opthalmologist before proceeding with any dental procedure.

The aim of this study was twofold: determine whether bubble formation in alginate is influenced by the sequence of water/powder addition prior to mixing, and to compare 4 different spatulation techniques. Porosity was significantly less for powder-first trials using manual spatulation (P < 0.05) but the sequence made no difference with the other techniques (P = 0.714). Surface porosity was significantly less for centrifugal and vacuum mixing compared to manual spatulation, while internal porosity was significantly less for centrifugal mixing compared to all the other techniques (P < 0.05).

This study sought to measure the microtensile bond strength of a nanofilled composite resin to human dentin after phosphoric acid etching followed by nonvital bleaching. Twenty extracted human maxillary premolars were prepared and assigned randomly to 4 groups (n = 5): Group 1 (control) – unbleached with no previous acid etching, Group 2 – bleached only, Group 3 – acid-etched for 15 seconds prior to bleaching, and Group 4 – acid-etched for 30 seconds prior to bleaching. There were no statistically significant differences of bond strength values among Groups 1-3; however, the mean values of Group 4 were statistically lower compared with the other groups.

It is important for every dentist to be aware of the maxillofacial manifestations of multiple myeloma (MM), especially with regard to early diagnosis, since injury can occur when MM is in its primary form in the maxillary bones. This case report presents a 58-year old man with mandibular swelling; his medical history indicated he had a fracture of the humerus a month earlier. The patient underwent chemotherapy for the MM, and a hemimandibulectomy was followed by the installation of a reconstructive plate for the fractured jaw.

This case report identifies a side effect of vitreoretinal surgery with a benign outcome—specifically, a referred pain or pressure from left eye surgery or an associated gas bubble to the upper left quadrant. Such cases underscore the need for a dentist and staff to inquire about all ocular procedures to avoid catastrophic patient vision loss due to nitrous oxide, which is absolutely contraindicated after vitreoretinal surgery that uses intraocular gas. Dentists should communicate with the patient’s opthalmologist before proceeding with any dental procedure.

This case report identifies a side effect of vitreoretinal surgery with a benign outcome—specifically, a referred pain or pressure from left eye surgery or an associated gas bubble to the upper left quadrant. Such cases underscore the need for a dentist and staff to inquire about all ocular procedures to avoid catastrophic patient vision loss due to nitrous oxide, which is absolutely contraindicated after vitreoretinal surgery that uses intraocular gas. Dentists should communicate with the patient’s opthalmologist before proceeding with any dental procedure.
