Evaluation of trabecular bone healing using fractal dimension analysis after augmentation of alveolar crests with autogenous bone grafts: a preliminary study
ConclusionAny clinical imaging method cannot fully reflect the histological microstructures of the bone. Evaluating the fractal analysis together with the clinical results can demonstrate adequate bone healing and quality prior to implant placement. Fractal analysis is a non-invasive, reproducible, method but further, prospective, randomized, controlled clinical studies are needed to estimate bone quality prior to implant placement.

Tonsillar actinomycosis that mimics tonsillar neoplasm
We report a case of tonsillar actinomycosis that causes massive, asymmetric enlargement of tonsil and mimics the neoplasia. The most common cause of asymmetric tonsil hypertrophy is tonsillar squamous cell carcinoma and lymphomas. Tonsillar actinomycosis is a rare entity that should be kept in mind, if cases cannot be clarified with clinical and laboratory findings, when radiological findings are suspicious about malignancy.

Brachytherapy with 198 Au grains for cancer of the floor of the mouth: relationships between radiation dose and complications
ConclusionOur study showed that the combination of EBRT and198Au grains brachytherapy for the floor of the mouth cancer patients might be associated with risks of developing complications of soft tissue ulcer and mandibular bone necrosis. (Source: Oral Radiology)

A comparative study between CT, MRI, and intraoral US for the evaluation of the depth of invasion in early stage (T1/T2) tongue squamous cell carcinoma
ConclusionsUS is the most accurate preoperative diagnostic tool for T1 and T2 squamous cell carcinoma; CT and MRI tend to have an overestimation of about 2 –3 mm and so caution is required. (Source: Oral Radiology)

Root canal morphology and symmetry of mandibular second premolars using cone-beam computed tomography
ConclusionsThe root morphology of mandibular second premolars in the Saudi population demonstrated a high degree of variability. The vast majority of mandibular premolars have a single root with one canal and a low prevalence of two rooted teeth. Contralateral mandibular second premolars exhibited great symmetry of roots and root canal configuration. (Source: Oral Radiology)

Place of a new radiological index in predicting pulp exposure before intervention for deep carious lesions
ConclusionRDT/TDT ratio is potentially helpful in predicting pulp exposure. However, the measurement errors on RDT and TDT being non-negligible and the interrater agreements poor, there is still place for advances through development of an automated process that will improve reliability and reproducibility of pulp exposure risk assessment.Clinical trialTrial registration number.

Differential diagnosis between calcifying odontogenic cyst and adenomatoid odontogenic tumor by computed tomography images
ConclusionWe report imaging findings that may be characteristic of COC and AOT, suggesting that CT findings may be useful for differentiating between COC and AOT. (Source: Oral Radiology)

Efficacy of cone-beam computed tomography with modified gray-scale range versus digital periapical radiography for the assessment of bone –implant interface gaps
ConclusionsCertain gray-scale ranges in CBCT enhance the assessment of bone –implant interface which brings the accuracy of CBCT closer to digital PA radiography as the modality of choice. (Source: Oral Radiology)

Diffusion-weighted magnetic resonance imaging of mandibular bone marrow: do apparent diffusion coefficient values of the cervical vertebrae and mandible correlate with age?
ConclusionsThe mandible area that most correlates with the cervical vertebrae, using ADC values, is the posterior trabecular area, below the inferior molars. Also, C2, C3, and C4 vertebrae ADC values inversely correlate with age, which demonstrates the bone qualitative changes in bone composition. ADC values may be useful for the qualitative assessment of bone quality to screen patients at osteoporosis risk. (Source: Oral Radiology)

Evaluation of mandibular morphologic measurements and trabecular structure among subgroups of impacted mandibular third molars
ConclusionThe trabecular structure and morphometric properties except for the angle of impaction do not affect impacted MM3s with adequate retromolar space and vertical angle. (Source: Oral Radiology)

Quantitative assessment of age-related changes in the mandibular bone marrow using apparent coefficient value
ConclusionThis study demonstrates that the normal ADC values of the mandibular bone marrow show significant negative correlation with increasing age. These findings will be useful in the diagnosis of bone marrow diseases. (Source: Oral Radiology)

Quantitative assessment of temporomandibular disc and masseter muscle with shear wave elastography
ConclusionThis study provides the normative quantitative elasticity values of disc and masseter muscle which could be a reference point for upcoming studies. Disc elasticity values are higher in women than men. Maybe this is one of the reason why TMD is more common in women. TMJ disc stiffness was significantly lower in the posterior part. SWE is a useful imaging method that can be used with routine ultrasonography in evaluation of the TMJ disc and masticatory muscles

Radiological spectrum of metastasis to the oral and maxillofacial region
ConclusionLesions with poorly demarcated margins with cortical destruction, accompanied by clinical signs of swelling, pain and paraesthesia in the absence of any inflammatory process, should raise suspicion for metastasis. Considering the poor prognosis of these metastatic lesions, the responsibility lies with the clinician to identify these lesions and make appropriate referrals. (Source: Oral Radiology)

Evaluation of oral air space volume in obstructive sleep apnea syndrome using clinical and postmortem CT imaging
ConclusionsIt was shown that the %air is an index to evaluate OSAS by CT imaging of the oral region. OSAS may be indicated when the %air value is ≦ 16.0% in deceased cases and ≦ 6.6% in clinical cases. (Source: Oral Radiology)
