This study investigated the correlation between femoral and lumbar spine bone mineral density and visual, qualitative mandibular bone pattern assessments. Radiomorphometric patterns assessed with panoramic radiographs correlated with dual-energy X-ray absorptiometry values, suggesting that these patterns are suitable for screening patients at risk of low bone mineral density.

Comparison of inflammation in the tongue with inflammation of the aorta and coronary arteries: an autopsy study of the histologic features and immunohistochemical markers

In a study of autopsied humans, inflammation in the submucosa, spongiosis, and higher immunostaining by IL-6 on the tongue were associated with higher immunostaining by IL-1α in the aorta. More intense presence of IL-6 in the tongue was also associated with increases in IL-6 and TNF-α in the aorta. Since these cytokines contribute to the process of atherosclerosis, it seems possible that proper treatment of lingual infections could reduce the risk of atherosclerosis.

This systematic literature review analyzed the effectiveness of cyanoacrylate adhesive as a substitute for conventional sutures after third molar extraction. The search process identified 5 randomized clinical trials with a total of 236 patients. Lower levels of postoperative pain were reported for cyanoacrylate in 3 studies, and lower rates of bleeding were reported in all studies.

Pseudopathologic findings on panoramic radiographs and utility of follow-up cone beam computed tomographic scans: a case series
John K. Brooks
Vandana Kumar
Azin Parsa
Jeffery B. Price
This article presents 4 cases of pseudopathologic disorders found on intraoral and panoramic radiographs. Subsequent use of cone beam computed tomography determined that the initial concerning findings represented anatomical or radiographic anomalies rather than pathologic processes, eliminating the need for surgical intervention.

This article used direct (spectrophotometric) and indirect (digital photographic) measurements of color changes to assess the shade matching and blending capabilities of a single-shade restoration in vivo. The tested composite did not meet the acceptability threshold for any CIEDE2000 color difference standard. The incisal third showed better results than the middle or cervical thirds.

Diagnosis, treatment planning, and comprehensive restoration of a patient with Costello syndrome: rationale and application of indirect composite resin onlays
Roger A. Solow
Patients with a complex problem set involving multiple levels of altered structure challenge the clinician to develop an individualized, appropriate treatment plan. An overview of complex, comprehensive restorations and the clinical case of a patient with Costello syndrome illustrate essential diagnosis and treatment planning concepts.

Assessment of the relationships between posterior root apices and the maxillary sinus floor: a comparison of panoramic radiography and cone beam computed tomography

Mir Mehdi Seyed Ashrafi
The relationships between the apices of posterior teeth and the maxillary sinus floor were evaluated, comparing the results of assessments performed with panoramic radiography and cone beam computed tomography (CBCT). When panoramic images indicate that premolar or molar roots are in contact with or have protruded into the sinus, the results are not definitive, and CBCT should be performed.

Hypoplasia and root dilaceration were observed in a permanent maxillary left central incisor 9 years after dental trauma of the primary tooth. Restoration was carried out with composite resin and resin-modified glass ionomer cement, and the clinical outcomes after 10 years revealed that the treatment successfully preserved the natural tooth with good periodontal health conditions.

A study of Brazilian adults used cone beam computed tomographic images to evaluate the prevalence and characteristics of 3 anatomical variants of the clivus: fossa navicularis magna, canalis basilaris medianus, and craniopharyngeal canal. The fossa navicularis magna was the most prevalent variation, especially in young adults aged 18 to 31 years. The variables sex and facial skeletal pattern did not affect the frequency of any variant.
