OBJECTIVE This guideline provides evidence-based recommendations on managing cerumen impaction, defined as an accumulation of cerumen that causes symptoms, prevents assessment of the ear, or both. We recognize that the term "impaction" suggests that the ear canal is completely obstructed with cerumen and that our definition of cerumen impaction does not require a complete obstruction. However, ...

This plain language summary serves as an overview in explaining earwax (cerumen). The summary applies to patients older than 6 months with a clinical diagnosis of earwax impaction and is based on the 2017 update of the Clinical Practice Guideline: Earwax (Cerumen Impaction). The evidence-based guideline includes research that supports diagnosis and treatment of earwax impaction. The guideline w...

The differential diagnosis of focal lung masses in childhood is large and includes mucoid impaction, congenital masses, inflammatory lung diseases, and neoplastic conditions. Mucoid impaction has a characteristic “finger-inglove” appearance on chest x-ray. The etiology of mucoid impaction can be quickly narrowed by a focused clinical and radiological evaluation. We describe an index patient and...

This study investigates the effect of air inlet size on (i) the flowfield generated in a dry powder inhaler, and (ii) the device-specific resistance, and the subsequent effect on powder deagglomeration. Computational fluid dynamics (CFD) analysis was used to simulate the flowfield generated in an Aerolizer with different air inlet sizes at 30, 45, and 60 l/min. Dispersion performance of the mod...

Deciduous teeth (dentes lactales, dentes decidua, dentes caduci) differ from permanent teeth by morphological and histological characteristics. Of the morphological characteristics, the most pronounced differences are in number, shape, size and color of teeth. A special fea­ ture is the existence of enamel­dentin ridge located on the vestibular surface of molars, which protects gingiva from foo...

OBJECTIVES The impaction of the second mandibular molar (MM2) has recently become more prevalent. Several etiological hypothesis have been proposed to investigate the association between skeletal features and impaction of MM2. The aims of this study were to analyze the skeletal features in patients with MM2 impaction and the association between arrested eruption of MM2 and the presence of the t...

Dentigerous cysts are frequently found in the maxilla. After radicular cysts, dentigerous cysts are those most commonly diagnosed, accounting for 20% of all jaw cysts. They are often asymptomatic and diagnosed incidentally during routine examinations. Clinical complications such as dental displacement, ectopic eruption, dental impaction, adjacent tooth root resorption, cortical expansion with f...

While impaction of tooth is widespread, multiple impacted teeth by itself is a rare condition and often found in association with syndromes such as cleidocranial dysplasia or Gardner's syndrome. A light of radiographic examination, we describe three Turkish young males with multiple impacted teeth who didn't possess any systemic conditions or syndromes involving both jaws. The first patient, a ...

The purpose of this study was to analyze the incidence and risk factors possible inferior alveolar nerve (IAN) injury after extraction mandibular third molars. A total 6182 patients were examined for 10,310 molar teeth. Panoramic radiography patients’ medical records used age, gender, impaction pattern molar. Cone beam computed tomography (CBCT) investigate detailed pathway evaluated presence s...

Acute as well as chronic and recurrent colic episodes were caused by right dorsal colon (RDC) impaction in 7.98% of all colic patients. Significantly higher statistical evidence was figured out in hucul horses, mares and 7-year-old animals. Diagnosis of RDC impaction was established on the basis of rectal palpation (68.75%) or laparotomy (31.25%). Yield of rectal palpation was limited by a diff...
