Evaluation of the predictors of oral health-related quality of life among 3-5-year-old children with dental trauma.

This study evaluated the influence of socio-demographic, clinical, and parental psychological factors on oral health-related quality of life (OHRQoL) and determined their predictors in preschool-aged children with traumatic dental injury (TDI). The study sample consisted of 324 dyads of children and their parents attending the Clinics of Pediatric Dentistry at Istanbul University. After clinical examination, the Sense of Coherence (SOC), Generalized Self-Efficacy Scale, Early Childhood Oral Health Impact Scale, and Multidimensional Health Locus of Control Scale-MHLC questionnaires were administered to the parents.

Dental Age in Precocious and Delayed Puberty Periods.

Objectives:  Precocious puberty indicates quick growth inception and delayed puberty indicates retardation in growth. This study aimed to investigate whether dental development is synchronous with somatic development.

Materials And Methods:  In this study, 62 girls and 34 boys with precocious puberty aged 5 to 9, 29 girls with delayed puberty aged 13 to 16, and 43 boys with delayed puberty aged 14 to 17; 169 children (91 girls and 78 boys) with normal development were compared about their dental ages through their panoramic radiographs by using the Demirjian method and skeletal ages from hand-wrist radiographs by using Greulich-Pyle atlas.

Management of regional odontodysplasia: a 10-year-follow-up case report and literature review.

The aim of this article was to review the literature and present a case of regional odontodysplasia (ROD) with special emphasis on clinical and radiographic features. A 6-year-old girl was referred to our department with the chief complaint of missing her permanent maxillary left central incisor, lateral incisor, and both of her canines. The gingiva of the involved region was enlarged, fibrous, and tense.

Rethinking isolated cleft lip and palate as a syndrome.

Objective: The goal of the present work was to use dental conditions that have been independently associated with cleft lip and palate (CL/P) as a tool to identify a broader collection of individuals to be used for gene identification that lead to clefts.

Study Design: We studied 1573 DNA samples combining individuals that were born with CL/P or had tooth agenesis, supernumerary teeth, molar incisor hypomineralization, or dental caries with the goal to identify genetic associations. We tested 2 single-nucleotide polymorphisms that were located in the vicinity of regions suggested to contribute to supernumerary teeth.

Nephrocalcinosis in Amelogenesis Imperfecta Caused by the FAM20A Mutation.

Background/aims: Enamel-renal syndrome is characterized by nephrocalcinosis, enamel defects, gingival hyperplasia and eruption failures. It has been recently identified that recessive mutations in the FAM20A gene result in amelogenesis imperfecta (AI)-gingival fibromatosis. The aim of this research to determine whether AI patients with known -FAM20A mutations also have nephrocalcinosis.

Recessive Mutations in ACPT, Encoding Testicular Acid Phosphatase, Cause Hypoplastic Amelogenesis Imperfecta.

Amelogenesis imperfecta (AI) is a heterogeneous group of genetic disorders affecting tooth enamel. The affected enamel can be hypoplastic and/or hypomineralized. In this study, we identified ACPT (testicular acid phosphatase) biallelic mutations causing non-syndromic, generalized hypoplastic autosomal-recessive amelogenesis imperfecta (AI) in individuals from six apparently unrelated Turkish families.

Prevalence and characteristics of talon cusps in Turkish population.

Background: Talon cusp is a rare dental anomaly characterized by a cusp-like projection, often including the palatal surface of the affected tooth. The aim of the present study was to investigate the prevalence and characteristics of talon cusps in a group of Turkish children.

Materials And Methods: The study population consisted of 14,400 subjects who attended the clinics of the Department of Pediatric Dentistry at the Istanbul University, Istanbul, Turkey.

Fam83h null mice support a neomorphic mechanism for human ADHCAI.

Truncation mutations in FAM83H (family with sequence similarity 83, member H) cause autosomal dominant hypocalcified amelogenesis imperfecta (ADHCAI), but little is known about FAM83H function and the pathogenesis of ADHCAI. We recruited three ADHCAI families and identified two novel (p.Gln457*; p.

A Complex Facial Trauma Case with Multiple Mandibular Fractures and Dentoalveolar Injuries.

The principles of management of mandibular fractures differ in children when compared to adults and depend on the specific age-related status of the growing mandible and the developing dentition. This paper presents a case report with a complex facial trauma affecting the mandibular body and condyle region and dentoalveolar complex. Clinical examination revealed soft tissue injuries, limited mouth opening, lateral deviation of the mandible, an avulsed incisor, a subluxated incisor, and a fractured crown.

An assessment of antibacterial activity of three pulp capping materials on Enterococcus faecalis by a direct contact test: An in vitro study.

Objective: The aim of this in vitro study was to evaluate antimicrobial activities of three different pulp capping materials; Biodentine, mineral trioxide aggregate (MTA) Angelus, and Dycal against Enterococcus faecalis and their durability with time.

Materials And Methods: Direct contact test was used for the assessment. Three sets of sealers were mixed and placed on microtiter plate wells: One set was used within 20 min of recommended setting time while others were used after 24-h and 1-week.

Clinical findings and long-term managements of patients with amelogenesis imperfecta.

The aim of this clinical case series is to present a diagnosis and different treatment methods of patients in different ages with amelogenesis imperfecta (AI) as well as further treatments during a 3-6 years follow-up period.

Effect of fibroblast growth factor and enamel matrix derivative treatment on root resorption after delayed replantation.

Background: Periodontal ligament (PDL) healing and long term prognosis of replanted avulsed teeth should rely on several factors including length of extra-oral dry time and type of the storage medium. The status of periodontal ligament is critical for the healing of replanted teeth. Different substances have been used for root surface treatment to promote formation of PDL and increase the survival of avulsed teeth submitted to replantation.
