The non-ossifying fibroma: a case report and review of the literature.

The non-ossifying fibroma (NOF) is a benign, non-neoplastic lesion most commonly seen in the metaphyses of the long bones in children. While rare, the NOF has been reported in the mandible. The NOF in the extra-gnathic skeleton has a characteristic radiographic appearance, is typically asymptomatic and has a variable histologic make-up. Correlation of the radiographic appearance, clinical presentation and histopathology allows for differentiation of the NOF from odontogenic and non-odontogenic cysts and tumors. We report a new case of this interesting entity and review the radiographic, clinical and histologic features of the gnathic NOF reported in the literature. A thorough search of the English language literature returned a total of 19 cases of NOF involving the gnathic bones.

A Preliminary Study on the Effects of Self-Reported Dietary Caffeine on Pain Experience and Postoperative Analgesia.

BACKGROUND: Caffeine reduces the amount of analgesic medications necessary to provide postoperative pain (POP) relief and augments treatments for headaches and dental pain. Despite considerable evidence of its beneficial effects, little is understood about the role of dietary caffeine consumption on baseline pain sensitivity or POP following oral surgery. METHOD: Baseline experimental pain testing (quantitative sensory testing [QST]) using four stimulus modalities was conducted on 30 healthy adults (53% females) before surgical extraction of four third molars. Self-reported caffeine ingestion was reported before QST, and on the day of surgery, preoperative and postoperative caffeine plasma concentrations (CPC) were measured by mass spectrometry. POP ratings were obtained at timed intervals. RESULTS: In QST, compared to subjects who self-reported no caffeine intake, those who self-reported caffeine ingestion demonstrated a higher pain sensitivity, particularly, on ramp and hold sustained heat at 44°C and 46°C, as well as a lower heat pain threshold and tolerance (p=0.05). Differences approached significance (p=0.06) in POP between subjects with CPC above 300 ng/mL and those with CPC below 300 ng/mL. Specifically, those with >300 ng/mL CPC had a slightly lower POP (mean 2.43, range 0-5) compared to those with <300 ng/mL CPC whose POP ratings were slightly higher (mean 2.89) with a greater variability (range 0-9.5). CONCLUSIONS: Self-reported, dietary caffeine intake was associated with higher QST ratings with lower threshold and tolerance particularly on heat pain modalities. External factors (i.e., analgesic dosage) may have played a role in the analgesic effects of caffeine on POP in oral surgery, especially in individuals with CPC exceeding 300 ng/mL who reported lower pain.

Assessment of oral health-related quality of life before and after third molar surgery.

PURPOSE: This study was designed to further our understanding of recovery after third molar surgery by using 2 instruments to measure quality of life outcomes, the more global Oral Health Impact Profile (OHIP-14), and the condition-specific Health-Related Quality of Life (HRQOL) instrument. PATIENTS AND METHODS: Clinical and quality of life data pre- and postsurgery from 63 patients with all 4 third molars below the occlusal plane, treated with topical minocycline during third molar surgery to reduce the incidence of delayed clinical healing, were available for analyses. Each patient was given 2 questionnaires to complete; the more global OHIP-14 and the HRQOL instrument designed to assess recovery after third molar surgery. Prevalence, Extent, and Severity of the OHIP-14 scores were calculated presurgery and for postsurgery days (PSD) 1, 7, 14. The percentage of patients reporting clinically relevant responses detrimental to quality of life from the condition-specific HRQOL instrument were reported for the same time frame. RESULTS: Study patients were most likely female, less than 25 years old, and Caucasian. Most (72%) had bone removed from both lower third molars. Median surgery time was 27 minutes (interquartile range [IQ], 20, 40 minutes.). Median surgeons' estimate of overall difficulty was 14 of a possible 28 (IQ 10, 18), and the median degree of difficulty for lower third molars was 8 of 14 (IQ 6, 10). Few patients (only 10%) had delayed clinical healing. Prevalence for all OHIP-14 items, percent of patients reporting items "fairly often" or "very often," were increased from presurgery on PSD 1 and then decreased on PSD 7 and PSD 14. OHIP-14 Severity scores, the sum of OHIP-14 responses, followed the same pattern as the Prevalence scores. OHIP-14 Severity scores on PSD 1 were 27 (IQ 16, 34), decreasing to 8 (IQ 3, 13) by PSD 7, and 1 (IQ 0, 5) by PSD 14. Recovery for outcomes addressed by both instruments followed a similar pattern and time course. However, each instrument also assessed distinctly different outcomes, adding information that could not be obtained by 1 instrument alone. CONCLUSION: Complementary instruments to measure quality of life outcomes provide a broader understanding of recovery after third molar surgery.

Impact of topical minocycline with third molar surgery on clinical recovery and health-related quality of life outcomes.

PURPOSE: Compare recovery for clinical and health-related quality of life (HRQOL) outcomes after third molar surgery in patients treated with or without topical minocycline at surgery. PATIENTS AND METHODS: Sixty-three patients at least 18 years of age with all 4 third molars below the occlusal plane were treated with topical minocycline during third molar surgery. Topical minocycline (1.0 mg in bioresorbable polyglycolide-co-dl-lactide [PGLA] sustained-release microspheres) was placed sequentially in bony defects after removal of lower third molars. Clinical and health-related quality of life (HRQOL) outcomes of these patients postsurgery were compared with those of a nonconcurrent control group (n = 60 patients) who did not receive antibiotics. The control group was selected using the same criteria and treated under the same surgical protocol as the antibiotic group. Differences between the groups were assessed with Cochran-Mantel-Haenszel row mean score statistics. RESULTS: The 63 patients in the minocycline group were treated at 4 clinical centers. The incidence of delayed clinical recovery, defined as a postsurgery visit with treatment, was significantly lower in the minocycline group compared with the control group. In the minocycline group, 10% had 1 postsurgery visit with treatment; no patient had 2 visits. In the control group without antibiotics, 28% had at least 1 postsurgery visit with treatment (P = .01) and 13% had at least 2 postsurgery visits with treatment. Recovery time to "no" or "little trouble" with chewing and mouth opening was significantly improved in the minocycline group (P < .05). CONCLUSIONS: Administration of topical minocycline with third molar surgery may improve clinical and HRQOL recovery in healthy adult patients with all 4 third molars below the occlusal plane, a presenting characteristic that has been suggested as a risk factor for delayed recovery.
