The purpose of this study was to assess the longitudinal relationships between enamel hypoplasia and caries experience of primary second molars. The study sample was 491 subjects who received dental examinations at both age 5 and 9 by the calibrated examiners. Four primary second molars (n = 1,892) were scored for the presence of enamel hypoplasia for each participant. Caries presence and numbe...

Renal hypoplasia refers to a congenitally small kidney where there is essentially normal residual parenchyma but smaller calyces, lobules, and papillae. This anomaly can be divided into two broad groups: complete (global) renal hypoplasia and segmental renal hypoplasia. In this study, a 3 days-old simmental calf was diagnosed with renal hypoplasia and unreconstructed exstrophic bladder. It pres...

PURPOSE Evaluation of the healing and persistence of a meshed composite skin graft applied without immunosuppression. METHODS The contraction of wounds grafted with 9:1 split-thickness autograft/1.5:1 allodermal mesh composite skin grafts (auto/allo MCSGs) was investigated. No immunosuppressive agent was applied. Male ACI rats and female Lewis rats reciprocally served as allodermis graft dono...

A 33-YEAR-OLD MAN, A 20-YEAR-OLD WOMAN, AND a 10-year-old boy with the clinical diagnosis of lichen nitidus (Figure 1A, Figure 2A, and Figure 3A, respectively) underwent imaging with confocal laser scanning microscopy (CLSM) (Vivascope 1500; Lucid-Tech Inc, Henrietta, New York). The mosaic CLSM images (Figure 1B, Figure 2B, and Figure 3B [3 3 mm, 2 2 mm, and 2 2 mm, respectively]) revealed roun...

binder’s syndrome is an uncommon entity characterized by midfacial hypoplasia along with class iii incisal relationship. the individuals with this syndrome are easily recognizable and the syndrome is mostly associated with other malocclusions. the current article presents two cases of this rare syndrome and describes its general features. key words: binder’s, midfacial hypoplasia, maxillofacial...

Two patients who shared similar presenting clinical features of anterograde and retrograde autobiographical amnesia typical of transient epileptic amnesia (TEA) underwent prolonged video electroencephalogram (VEEG) monitoring and were found to have sleep-activated epileptiform activity and frequent subclinical bitemporal seizures predominantly during sleep. Case 1 is a 59-year-old woman whose p...

Scarring, which occurs in essentially all adult tissue, is characterized by the excessive production and remodeling of extracellular matrix by α-smooth muscle actin (SMA)-expressing myofibroblasts located within connective tissue. Excessive scarring can cause organ failure and death. Oral gingivae do not scar. Compared to dermal fibroblasts, gingival fibroblasts are less responsive to transform...

This paper deals with the basic notions of k-tautimmersions . These notions come from two special cases; that is, tight and taut immersions. Tight and taut based on high and distance functions respectively and their basic notions are normal bundle, endpoint map, focal point, critical normal. We generalize hight and distance functions to cylindrical function and define basic notions of k-taut ...

objective: objective: dermal papilla and hair epithelial stem cells regulate hair formation and growth cycle. damage to or losing of these cells can cause hair loss. although several studies have claimed to reconstitute hairs using rodent cells in animal model, a stable human hair follicle reconstitution protocol needs more studies. here in this study we evaluated hair induction through injecti...
