BACKGROUND/AIM: The extra-alveolar dry period and storage medium in which a tooth is kept prior to replantation remain critical factors affecting the survival and repair potential of the periodontal ligament in avulsed teeth. When replantation is not immediate, replacement root resorption (RRR) is the most common complication. The aim of this histological study was to evaluate the effect of immediate controlled-orthodontic forces in periodontal healing of replanted teeth in a canine model...

STATEMENT OF PROBLEM: Clinicians are currently unable to quantify the psychosocial, functional, and esthetic effects of prosthetic interventions to replace teeth. Understanding the effects of treatment to replace teeth on oral health-related quality of life (OHRQoL) is important for informed consent. A systematic review of the evidence of OHRQoL improvements with prosthodontic tooth replacement and a comparison of outcomes between treatment modalities is therefore indicated. PURPOSE: The purpose of this systematic review was to examine the OHRQoL of patients with partial edentulism after different dental prosthetic treatments...

OBJECTIVES: Root-canal treated molars can be directly restored, usually using resin-bonded-composite restorations (RBCs), or indirectly restored using full or partial crowns (FCs/PCs). Both the initial treatment costs and the risks of restorative and endodontic complications differ between RBCs and FCs/PCs. We aimed to assess the cost-effectiveness of RBCs versus FCs/PCs for restoring root-canal treated molars. METHODS: A mixed public-private payer's perspective within German healthcare was taken...

CONTEXT/OBJECTIVES: Clinical studies show a mean bond failure rate of orthodontic brackets, which ranges between 6% and 8%, with a predominance for the second mandibular premolars. The pre-coated flash-free adhesive ceramic brackets allow to obtain, according to their manufacturer, a low bond failure rate, while ensuring a simplified implementation. The aim of this study was to measure the shear bond strength of ceramic brackets bonded with the direct method using a pre-coated flash-free adhesive system, and to compare it with the shear bond strength of the old generation precoated brackets and that of operator coated brackets to the buccal surface of the second mandibular premolars...

Alazami syndrome (AS) (MIM# 615071) is an autosomal recessive microcephalic primordial dwarfism (PD) with recognizable facial features and severe intellectual disability due to depletion or loss of function variants in LARP7. To date, 15 patients with AS have been reported. Here we describe two consanguineous Algerian sisters with Alazami PD due to LARP7 homozygous pathogenic variants detected by whole exome sequencing. By comparing these two additional cases with those previously reported, we strengthen the key features of AS: severe growth restriction, severe intellectual disability and some distinguishing facial features such as broad nose, malar hypoplasia, wide mouth, full lips and abnormally set teeth...

OBJECTIVE: This study aimed to compare the periodontal status of LTC with healthy controls. METHODS: Fifty liver transplant candidates (LTC group) and fifty patients without liver disease (control group) underwent a complete periodontal examination. The groups were matched according to sex, age and smoking status. A structured questionnaire was applied to record demographic data, systemic health and information related to liver disease. Full-mouth complete periodontal examination of six sites per tooth was performed: gingival recession (GR), probing depth (PD), attachment loss (AL), bleeding on probing (BOP) and visible plaque index (VPI)...

Bragg filters stand as key building blocks of the silicon-on-insulator (SOI) photonics platform, allowing the implementation of advanced on-chip signal manipulation. However, achieving narrowband Bragg filters with large rejection levels is often hindered by fabrication constraints and imperfections. Here, we show that the combination of single-side corrugation asymmetry and subwavelength engineering provides a narrowband response with large corrugations, overcoming minimum feature size constraints of conventional Si Bragg filters...

OBJECTIVES: Amelogenesis imperfecta (AI) is a rare, genetically determined defect in enamel mineralization. Several problems are associated with AI: hypersensitivity, wear, restorations requiring replacement, gingivitis, aesthetic problems, and social avoidance. We conducted a randomized controlled trial of crown therapy in young individuals with AI showing excellent results. This study reports results from a long-term-follow-up with focus on quality, longevity and adverse events. METHODS: The RCT included 27 patients (aged 11-22 years) with severe AI in need of crown therapy and used a split-mouth technique...
