Correlations with clinical and radiologic findings and prevalence of osteopenia/osteoporosis in the patients with bilateral temporomandibular joint osteoarthritis.

This study aimed to evaluate the prevalence of osteopenia/osteoporosis in patients with bilateral temporomandibular joint osteoarthritis (TMJ-OA) and its correlations with clinical and radiological findings. A total of 95 patients with bilateral TMJ-OA diagnosed by CBCT were included in the study. Clinical and radiological findings and bone mineral density (BMD) scores were recorded.

The Mediating Role of Psychological Resilience in the Relationship between Emotional Reactivity, Intolerance of Uncertainty and Psychological Maladjustment in Children Receiving Orthodontic Treatment.

The aim of this research was to examine the various psychological characteristics that affect psychological maladjustment in children undergoing orthodontic treatment. In this context, the predictive and mediating relationships between emotional reactivity, intolerance of uncertainty, psychological resilience and psychological maladjustment were considered. The study was conducted cross-sectionally with 543 children and adolescents aged 10−18 years, who were being treated at a state university orthodontic clinic in Turkey.

Cone beam computed tomography imaging of ponticulus posticus: prevalence, characteristics, and a review of the literature.

Objective: The aim of this study was to investigate the frequency of ponticulus posticus (PP) using cone beam computed tomography (CBCT) and to describe the radiologic characteristics of the detected cases.

Study Design: The presence and types of PP were investigated on 730 CBCT images.

Results: PP was found in 17.

Relationship among Schneiderian membrane, Underwood's septa, and the maxillary sinus inferior border.

Background: Osseo-integrated implants are increasingly being used to restore functional dentition; however, in the posterior region, implant placement can be problematic because of inadequate bone height. In this condition, maxillary sinus floor elevation surgery has become the treatment of choice. The presence of anatomic variations within the maxillary sinus such as Underwood's septa and thin Schneiderian membrane decreases the success of the sinus floor elevation.

Prevalence of the types of the petrotympanic fissure in the temporomandibular joint dysfunction.

Background: Petrotympanic fissure (PTF) is a fissure in the temporal bone that runs from the temporomandibular joint (TMJ) to the tympanic cavity (TC). In PTF, the discomallear ligament (DML) connects the malleus in the tympanic cavity and the articular disc and capsule of the temporomandibular joint. PTF with the DML is a possible cause of aural symptoms related to temporomandibular joint dysfunction (TMD).

Quantitative EDXRF analysis of Ca, K, Mn and Na in normal and pathological adult-human teeth.

This work relates to the measurement of calcium, potassium, manganese and sodium levels in adult-human teeth from female and male patients and normal subjects. Energy dispersive X-ray fluorescence (EDXRF) technique was used for the measurements. Pathological and non-pathological adult-human teeth samples were collected from one male human patient and one female human patient who attended the dental clinic.
