ABSTRACT
OBJECTIVE: The aim of this in vitro study was to evaluate the effects of clear and opaque fissure sealants on readings of laser fluorescence (LF) and light-emitting diode (LED) based caries detection devices. BACKGROUND DATA: When planning patient care, the practitioner needs to consider any changes in the status of the sealed surface for the long-term success of the sealant. As visual inspection is difficult to perform on sealed surfaces, adjunct diagnostic methods must be used to improve follow-up assessments and increase the accuracy of caries diagnosis. METHODS: Forty-six freshly extracted permanent human molars were selected and divided into two groups. Each group was treated with a different sealant (clear and opaque). The teeth were measured twice by two blinded observers using an LF-based and an LED-based device before and after sealing. The data were analyzed using Wilcoxon's matched-pairs signed-rank test and a paired t-test. Cohen's κ and the intraclass correlation coefficient were used to examine intra- and inter-examiner repeatability. RESULTS: The values of the LED device were significantly higher after the application of the opaque sealant, but there was no statistically significant difference after the application of the clear sealant (p=0.15). The LF-based device readings were also significantly lower after both the clear and the opaque sealant applications (p<0.001). CONCLUSIONS: The readings from the LF-based device were affected by both sealants. The readings from the LED-based device were affected by the opaque sealant but not by the clear sealant.

PURPOSE: The objective of this study was to assess gonial angle under the angle classification by comparing panoramic radiograph and lateral cephalometric radiograph. MATERIALS AND METHODS: 49 patients (25 males, 24 females) with an age range of 12-29 years participated in the present study. Subjects were retrospectively selected among those categorised as skeletal and dental Class I, II, and III malocclusion group. Using lateral cephalometric radiograph, mandibular and ramal planes were drawn and based on these planes. Gonial angle was determined from two tangents which were drawn from the inferior border of the mandible and posterior borders of the condyle and ramus of both sides in the panoramic radiographs. Multiple comparison tests (ANOVA) were used to determine differences between the three angle groups. RESULTS: There were no significant differences between Class I, II, and III malocclusion group values of gonial angles determined by lateral cephalometric radiograph and panoramic radiographs (P > 0.05). CONCLUSION: Panoramic radiograph results were shown to be as reliable as lateral cephalometric radiograph in all angle classifications. Panoramic radiography can be used as an alternative radiographic technique to detect gonial angle in orthodontic patients.

OBJECTIVES: The aims of this study were to evaluate the influence of gender and dental status on the mental index, mandibular cortical index and panoramic mandibular index from dental panoramic radiographs in elderly who had osteoporosis or did not have osteoporosis. METHODS: Panoramic radiographs of 487 elderly dental patients (age range 60-88 years) were evaluated. It were recorded osteoporotic status according to the patients' medical anamnesis and values of the mandibular cortical index (MCI), panoramic mandibular index (PMI), mandibular cortical width (MCW) RESULTS: Dental status was statistically significantly associated with the mandibular cortical width, panoramic mandibular index and the categories of MCI (P<.05). There were statistically different mandibular cortical width and panoramic mandibular index values in patients with osteoporosis and without osteoporosis (P<.05) CONCLUSIONS: Our study showed that there were statistically significant differences according to gender, dental status, and values of the MCW, MCI and PMI between patients with and those without osteoporosis.
ABSTRACT
Garlic is an herb which has been used by many cultures for treating various health problems for centuries. Uncontrolled use of herbal remedies, known as alternative treatment methods, may lead to side effects and serious treatment complications. This study aimed to draw attention to complications related to alternative treatment methods and to review the literature in the light of this case.A female patient who had been treated for trigeminal neuralgia was admitted to our clinic complaining of severe pain on the left side of her face. In anamnesis, the patient reported that she had applied garlic topically to this region. Extraoral examination revealed a broad cutaneous burn on the same region. According to a dermatology consultation, a treatment for cutaneous burns was applied and severe trigeminal neuralgia pain was eliminated with glycerol injection by an oral and maxillofacial surgeon.
