Labial adhesion

INTRODUCTION: Structural abnormalities or anomalies in the anterior teeth, also known as the aesthetic zone, are an important problem for patients and a challenge for dentists. Structural abnormalities or tooth anomalies can change in color, shape, and function. Most dentists prefer minimally invasive aesthetic treatment. One of the aesthetic treatment options for anterior teeth is veneers. Veneer is a restoration that covers the labial part of the tooth with a thin layer of material to correct abnormalities in the color, shape, or function of the tooth...

OBJECTIVE: Intraoral scanner (IOS) can acquire three-dimensional color images of teeth. Thus, the detection of areas with plaque adhesion stained by plaque-disclosing solutions using an IOS could be a potential oral hygiene evaluation method. This study aimed to verify the usefulness of obtaining O'Leary's plaque control record (PCR) measurements using an IOS in clinical practice. METHODS: Twenty patients with >20% PCR measurements who underwent oral prophylaxis were enrolled in this study...

MATERIALS AND METHODS: Ninety extracted teeth were divided into 6 subgroups ( n = 15) based on the antioxidant applied: Group I: Bleaching + application of 10% SA solution for 60 minutes...

Turner syndrome (TS) is a rare clinical condition associated with a completely or partially absence, or structural abnormality of an X chromosome, mainly representing as short stature and skeletal anomalies, female hypergonadotropic hypogonadism and infertility. Skin is frequently involved in TS, especially autoimmune diseases like vitiligo and lichen sclerosus (LS). Here, we present a 10-year-old Chinese girl with TS combined with both vulvar LS (VLS) and extragenital LS, who had been misdiagnosed as eczema and vitiligo for years...

After pediatric residency, the author worked in a rural community where he was able to immediately practice skills acquired during training such as intubations, bag-mask ventilation, IV placement, ear irrigation, foreign body removal from eyes and ears, abscess incision and drainage, intraosseous placement for rapid hydration of a severely dehydrated infant, EKG, X-ray readings, and ear-irrigations to cite but a few examples. Furthermore, the writer acquired other high-valued procedural skills such as neonatal male circumcision, frenotomy, ligation of supernumerary digits, and manual separation of labial adhesions...

The prism-interprisms level of the enamel hierarchical microstructure is the largest degree of structural variation and most sophisticated structural adaptation. We studied the effect of the prism-interprisms three-dimension spatial microstructure on the enamel bond strength. We prepared 11 groups of enamel segments: longitudinally sectioned segments with or without a 45-degree bevel (group = 2), horizontally sectioned segments with or without a 45-degree bevel of three regions (the incisal, middle, and cervical) (group = 6), and tangential (labial) sectioned segments of three regions (the incisal, middle, and cervical) (group = 3)...

AIMS: This study aimed to characterize the prevalence of development defects of enamel (DDE) in patients with cleft based on the cleft phenotype and explore the relationship between surgical procedures and different types of DDE. MATERIAL AND METHODS: In this cross-sectional study, 290 standardized orthodontic documentation and medical records from a reference hospital were evaluated, which treated patients with: cleft lip (CL), cleft lip with alveolar bone involvement (CLa), cleft lip and palate (CLP), cleft palate (CP), cleft median (CM), and considering laterality as unilateral or bilateral...

Introduction Shear bond strength is indispensable to prevent the debonding of orthodontic brackets. Lasers have been proven to alter the bond strength of orthodontic brackets, but their efficiency has not been validated in many trials. The study aimed to evaluate the impact of the Er,Cr:YSGG laser on the bases of orthodontic brackets and determine their bond strength with the enamel surface. Materials and methods The Waterlase iPlus (made in the USA in 2012), comprising an Er,Cr:YSGG laser, was used. Based on the surface treatment of brackets, two groups were assigned (n=10), comprising laser-treated and untreated bracket bases...

BACKGROUND: Genital inflammation is one of the most frequent clinical complaints among girls, which was easily overlooked by the general public. This study aimed to investigate the patterns and epidemiological characteristics of pediatric and adolescent female genital inflammation in China. METHODS: A retrospective observational study (2011 to 2018) was conducted among all female patients under the age of 0-18 years at the Department of Pediatric and Adolescent Gynecology of The Children's Hospital, Zhejiang University School of Medicine...

BACKGROUND: Rubinstein-Taybi syndrome (RSTS) is a multi-system neurodevelopmental condition caused by deficiency of CREBBP (16p13.3) or EP300 (22q13.2). Müllerian agenesis, or Mayer-Rokitansky-Küster-Hauser syndrome (MRKH), is defined as congenital agenesis of the uterus, cervix, and upper vagina without definite genetic cause. INDEX CASE AND CASE SERIES: We present a 14-year-old female with RSTS type 1 (CREBBP, c.4395-2A>C) and MRKH, the first documented in the literature...

The Pseudogastromyzon genus, consisting of species predominantly distributed throughout southeastern China, has garnered increasing market attention in recent years due to its ornamental appeal. However, the overlapping diagnostic attributes render the commonly accepted criteria for interspecific identification unreliable, leaving the phylogenetic relationships among Pseudogastromyzon species unexplored. In the present study, we undertake molecular phylogenetic and morphological examinations of the Pseudogastromyzon genus...

OBJECTIVE: To retrospectively analyze sex chromosomal abnormalities and clinical manifestations of children with disorders of sex development (DSD). METHODS: A total of 14 857 children with clinical features of DSD including short stature, cryptorchidism, hypospadia, buried penis and developmental delay were recruited from Zhengzhou Children's Hospital from January 2013 to March 2022. Fluorescence in situ hybridization (FISH) and chromosomal karyotyping were carried out for such children...

Neural cell adhesion molecules (NCAMs) are large cell-surface glycoproteins playing important roles in cell-cell and cell-extracellular matrix interactions in nervous system. Recent study identified a homologue of NCAM (CgNCAM) from the Pacific oyster Crassostrea gigas. Its ORF was of 2634 bp which encodes a protein (877 amino acids) consisting of five immunoglobulin domains and two fibronectin type III domains. CgNCAM transcripts were broadly distributed in oyster tissues especially in mantle, labial palps and haemolymph...

OBJECTIVES: Esthetic restorations such as monolithic zirconia crowns are highly requested for adults nowadays. Bonding orthodontic braces on this type of material became a challenge for orthodontists, because of the special surface treatment needed. This study aims to assess the shear bond strength (SBS) of metal, and ceramic brackets bonded on two types of zirconia ceramics, surface roughness (SR) after different surface treatments for their surfaces, and adhesive remnant index (ARI)...

Labial adhesion (LA) and vaginal destruction are very rare conditions in women. We report a 40-year-old woman with severe LA and distal vaginal stenosis after a radical hysterectomy at the age of 35. Completely destruction of vaginal epithelium, severe recurrent LA, voiding symptoms, and chronic pelvic pain occurs for her due to the repeated vaginal dilatation and low estrogen level. A combination of ileal vaginoplasty (IV) and labia majora flap was used in two surgical stages for treatment. After surgery, the patient's urinary symptoms and pelvic pain were relieved and she was able to have sex with her partner...

The silk produced by Lepidoptera caterpillars is a mixture of proteins secreted by the transformed labial glands, the silk glands (SG). The silk fiber consists of insoluble filamentous proteins that form a silk core and are produced in the posterior part of the SG and soluble coat proteins consisting of sericins and various other polypeptides secreted in the middle part of the SG. We constructed a silk gland specific transcriptome of Andraca theae and created a protein database required for peptide mass fingerprinting...

BACKGROUND: Topical estrogen treatment has been considered the first-line treatment of labial adhesions in prepubertal girls. However, the effect of topical estrogen cream is different according to studies, and no study compared estrogen cream to observation. OBJECTIVE: This study aims to investigate the efficacy of topical estrogen cream treatment compared with observation in prepubertal girls with labial adhesions. STUDY DESIGN: The medical records of prepubertal girls diagnosed with labial adhesions from April 2005 to June 2019 were retrospectively analyzed...
