    Special Patient Care Factor V Leiden thrombophilia: dental considerations

    John K. Brooks 
    Adam Elrafei
    Robert A. Ord

    Factor V Leiden thrombophilia is a relatively common inherited disorder of hypercoagulability that has received minimal attention in the dental literature. This review examines related demographic information, risk factors, comorbidities, the thrombotic mechanism, clinical features, diagnostic measures, and medical management strategies.

    Anesthesia and Pain Management Buccal injection of articaine to anesthetize the palatal mucosa

    Khadry Galil

    To explore the potential mechanism by which buccal infiltration results in palatal anesthesia, human hemimaxillae were sectioned and measured in 3 planes. Buccal cortical plate, palatal cortical plate, and total buccopalatal thickness measurements revealed no statistically significant differences along the maxilla (P > 0.05). The pharmacologic properties of articaine, coupled with the uniformly thin, cancellous maxillary bone, provide a plausible explanation for the success of palatal anesthesia achieved through buccal infiltration of articaine.

    This in vitro study evaluated the effect of previous irrigation with chlorhexidine (CHX) on the bond strength of a calcium silicate–based material in furcal repair. Irrigation with CHX before furcation repair did not result in significant differences in the push-out bond strength of the material.

    For an 18-year-old man with necrotizing ulcerative gingivitis, an initial phase of supragingival plaque and calculus removal and twice-daily mouthrinsing with chlorhexidine, followed by subgingival scaling and establishment of a regular periodontal maintenance regimen, restored periodontal health.

    A split-mouth design in a single patient was utilized to assess the final tooth color and tooth sensitivity resulting from 2 different bleaching protocols using 35% hydrogen peroxide: 1 application for 45 minutes and 3 applications for 15 minutes each. There was no difference in the final esthetic results of the 2 protocols, and the patient experienced no tooth sensitivity with either protocol.

    The aim of this study was to compare the effect of conventional aging (6 months of water storage) and accelerated aging (pH cycling) on the dentin bond strength of 4 adhesive systems. Microtensile bond strength testing showed that neither of the experimental aging methods significantly affected the dentin bond strength of any of the adhesives.

  • Oral and Maxillofacial Surgery Management of iatrogenic dislodgment of a mandibular third molar into the pterygomandibular space

    Vikram Shetty

    Although the surgical extraction of the mandibular third molar is routinely performed in dental clinics, the precise management of complications associated with it requires thorough knowledge and experience in the field of oral and maxillofacial surgery. Iatrogenic dislodgment of a tooth or its fragment is a rare complication and usually occurs when excessive, uncontrolled forces are applied via elevators. It also is possible that this rare complication may be underreported. This case report describes the retrieval, under local anesthesia, of a mandibular left third molar crown from the posterosuperior region of the pterygomandibular space after iatrogenic dislodgment.

  • Implants The influence of impression coping splinting on the accuracy of the open-tray technique

    The objective of this study was to examine the effect of splinting of the impression copings on the accuracy of the cast when the open-tray technique is used. An epoxy master cast with 3 implants was fabricated. The first 2 implants were parallel to each other and perpendicular to the horizontal plane (implants A and B), and the third implant (implant C) had a 25-degree inclination. A passively fitting metal framework that was fabricated over this master cast was used to measure accuracy of fit. Ten casts were fabricated from this epoxy resin master cast with the use of polyether and the open-tray technique. For the first 5 casts, the impression copings were splinted with dental floss and autopolymerizing acrylic resin; in the next 5 casts, the impression copings were not splinted. The metal framework in the master cast was fixed in the new specimens, and the microgap between this prosthesis and the implant analogs was evaluated. The specimens were observed under an optical microscope, and microgap measurements were made on photographs taken at a standardized magnification of 40×. The inclined implant C had the smallest mean microgap among the 3 implants, but the differences were not statistically significant. Microgaps for all 3 implants were smaller when they were splinted, but the difference from the mean of the nonsplinted counterpart was statistically significant only for the inclined implant. The results suggest that there is no clinical advantage in splinting the impression copings for parallel implants. On the other hand, when the implants are not parallel, splinting of the impression copings can result in greater accuracy of the fabricated cast.
