Bone density assessment using CBCT is an efficient method and significantly correlated with implant stability parameters and Lekholm and Zarb index. Thus, it is possible to predict initial implant stability and possibility of immediate or early loading using CBCT scans prior to implant placement.

The aim of this prospective study was to examine possible benefits of low-level laser therapy (LLLT) on soft and hard tissue healing after endodontic surgery. Seventy-six endo-surgery cases on maxillary incisors were included. The patients were assigned randomly into control and laser groups. In the laser group, gallium-aluminum-arsenide (GaAlAs) diode laser irradiation (810 nm, 129 mW, 3.87 J/cm) was performed immediately after surgery and daily for postoperative 7 days from buccal and palatal surfaces (5 min for each side). In the control group, patients were not subjected laser therapy. The patients were compared in terms of pain, clinical and radiological findings, and life quality indexes [Oral Health Impact Profile-14 (OHIP-14) and General Oral Health Assessment Index (GOHAI)]. Seventy-one patients completed the study (n = 37 for control group, n = 34 for laser group). The laser group showed better results in edema, wound healing, and the number of analgesic tablets used on the 1st, 3rd, and 7th postoperative days. Significant reduction in ecchymoses was observed in the laser group on the postop 3rd and 7th days. The patients had significantly lower pain on the 1st and 3rd postop days in laser group. The laser group showed significantly better results in OHIP-14 and GOHA indexes on postop days 1 and 3. The laser group showed significantly favorable results in terms of bone density, defect volume and area, and periapical index in the postop 3rd month. This study concluded that LLLT improved soft and hard tissue healing after endodontic surgery and also showed favorable effects on pain and life quality of patients especially in the early phase of healing period.

IntroductionThe purpose of this study was to assess the structural characteristics of styloid process (SP) by cone-beam computed tomography (CBCT) examination in a patient population suffering from orofacial pain. The second aim was to assess the prevalence of elongated SP and its relation to gender, site and subjective symptoms in the study population.MethodsClinical and radiographic records of 208 patients were evaluated retrospectively. Radiological examinations including measurements of the structure, length, and medial angulations of SP were performed on CBCT images.ResultsOut of 208 patients, 96 (46%) had not-elongated SP, 28 (13%) had left side, 16 (8%) had right side, and 68 (33%) had bilateral elongation of SP. The patients with elongated SP had significantly decreased angle values. There were no statistically significant differences in length values of SP between males and females in both groups. Significantly increased prevalence of symptoms except headache was observed in patients with elongated SP.ConclusionsThis study presents the CBCT as an alternative method to CT or panoramic radiographs for the measurement and the assessment of the styloid process. Patients suffering from orofacial pain, who also had elongated SP, had increased rate of corresponding neurological complaints compared with non-elongated ones.
