Retrospective study of the anterior loop of the inferior alveolar nerve and the incisive canal using cone beam computed tomography.
The mental foramen is an important landmark during surgical procedures such as osseous grafting or the placement of dental implants. To avoid injuring the mental nerve, it is important both to carefully assess the location of the mental foramen and to determine whether an anterior loop of the mental nerve or the incisive canal lies mesial to it. The objective of this study was to quantify the ability of cone beam computed tomography (CBCT) to measure the length of the mental nerve loop, the length and diameter of the incisive nerve canals, and the incisive canal path. ⋯ CBCT provides an accurate means to identify critical anatomical features in the anterior mandible during preoperative surgical planning.

Effects of implant surgery on blood pressure and heart rate during sedation with propofol and midazolam.
Intravenous (IV) sedation is commonly used in dentistry. However, no report has yet been published regarding age, hypertension, and antihypertensive drugs during implant surgery and their relationship with changes in blood pressure (BP) and heart rate in implant surgery under IV sedation with propofol and midazolam. ⋯ IV sedation using midazolam and propofol reduces hypertensive risks during implant surgery. Nevertheless, care must be taken, especially in older hypertensive patients and in hypertensive patients on ARBs or ARBs+CCBs.

Comparative StudyEvaluation of guided bone regeneration with poly(lactic acid-co-glycolic acid-co-ε-caprolactone) porous membrane in lateral bone defects of the canine mandible.
The aim of this study was to qualitatively evaluate a poly(lactic acid-co-glycolic acid-co-ε-caprolactone) (PLGC) membrane as a barrier for guided bone regeneration in the canine mandible and to compare it to a nonresorbable polytetrafluoroethylene (PTFE) membrane. ⋯ Compared to TR-PTFE, the macroporous bioresorbable PLGC membrane did not significantly increase the amount of new bone in defect sites, but it facilitated the regeneration of mature bone.

Randomized Controlled Trial Comparative StudyUtility of bispectral index monitoring during intravenous sedation in the dental office.
This research sought to compare two different systems to monitor sedated patients undergoing implant surgery in the dental office: the bispectral index (BIS) and the Ramsay scale. This information was used to establish an optimal BIS range for surgery in these patients and to calculate differences in drug consumption in both groups. ⋯ The optimal BIS value during intravenous sedation in sedated ambulatory patients in dental surgery should be within the 80 to 85 range. BIS monitoring allows for reduced consumption of propofol, fentanyl, and midazolam.

Bone regeneration with algae-derived hydroxyapatite: a pilot histologic and histomorphometric study in rabbit tibia defects.
Algipore is a biologic hydroxyapatite derived from calcifying maritime algae. The present study evaluated this material histologically and histomorphometrically after implantation in rabbit tibia defects for 4 weeks. ⋯ The present rabbit study confirmed the high osteoconductivity and resorbability of this biomaterial.
