This study aimed to evaluate the efficacy of fluoride-free remineralizing agents in initial enamel caries, with and without combined Er,Cr:YSGG laser application. The remineralization effect of various agents and their combinations on artificial initial caries was investigated using 10 experimental groups (n = 7): NC, negative control; PC, positive control; TM, calcium-phosphate compounds (CPP-ACP); TD, theobromine-containing toothpaste; RG, ROCS® remineralizing gel; L, Er,Cr:YSGG laser (2780 nm; 0.25 W; repetition rate, 20 Hz; pulse duration, 140 μs; tip diameter, 600 μm; without air/water cooling); L + fluoride toothpaste; L + TM; L + TD; and L + RG.

The aims of this study were to examine the knowledge, attitude, and self-perceived competency towards preventive dentistry among final-year dental students and to investigate their preventive practice for high-caries-risk children. Data were collected from a convenience sample of 126 dental students using a questionnaire.

Specimens immersed in a corrected simulated body solution (c-SBF) for 1, 30 and 90 days were used. In all test materials, the Ca and Si concentrations in the root dentine were found to be significantly higher, whereas the Ca/P and Si concentrations increased over time (P < 0.

Materials And Methods: Data were collected from 72 children with and without CB. A questionnaire was applied to parents/carers to obtain information about nutritive and non-nutritive sucking habits.
Article Synopsis
- The study explores the oral microbiome differences between children with Kostmann syndrome, who have low neutrophil levels, and healthy children, focusing on how immune system diseases affect oral health.
- Researchers conducted DNA analyses of saliva from both groups and found that Kostmann patients exhibited higher plaque, deeper periodontal pockets, and lower bacterial diversity compared to healthy controls.
- The results indicate a unique microbial profile in Kostmann syndrome patients, highlighting specific bacterial types and supporting the idea that immune system disorders significantly influence oral microbiota health.
Purpose: The aim of the present study is to determine the prevelance and clinical status of mesiodens in a group of non-syndromic Turkish children, with an analysis of the associated clinical-eruptive complications.
Materials And Methods: This study sample consists of 58142 pediatric patients'. Standard equipment and films were used in the suspected patients.
Importance of knowledge of the management of traumatic dental injuries in emergency departments.
Ulus Travma Acil Cerrahi Derg
March 2018
Background: Hospital emergency departments (EDs) are confronted with managing dental emergencies of both traumatic and non-traumatic origin. However, the literature suggests inadequate knowledge of the management of traumatic dental injuries (TDIs) among medical professionals. The aim of this study was to investigate the knowledge and attitudes regarding management of TDIs among Istanbul ED physicians.

Subjects And Methods: 256 patients (mean age: 15.80 ± 2.
Article Synopsis
- The study aimed to explore how the length of the lingual frenulum is related to irregularity of mandibular incisors and different types of occlusion in children with ankyloglossia.
- Eighty children aged 7 to 12 years with ankyloglossia were analyzed, measuring the crowding of mandibular incisors and determining occlusion types, using statistical tests for analysis.
- Results showed that while there was a significant correlation between frenulum length and incisor irregularity, mild and moderate ankyloglossia did not significantly affect incisor crowding or occlusion type.
Aim: The aim of this study was to evaluate the knowledge of sports participants regarding emergency management of dental trauma and the awareness about mouthguards.
Methods: A specific questionnaire regarding knowledge, experiences and behaviours after dental trauma and the use of mouthguard was distributed to 359 sports participants up to 18 years of age. The sports involved were basketball, swimming, volleyball, soccer, tennis, badminton, handball, athleticism, golf, gymnastics, water polo and karate.
Predominant causes and types of orofacial injury in children seen in the emergency department.
Ulus Travma Acil Cerrahi Derg
May 2013
Background: The aim of this study is to determine the type and cause of traumatic orofacial injuries in children up to 18 years of age.
Methods: This retrospective study involved data collected from 12055 patients that came to Istanbul University, Medical Faculty, Department of Emergency in 2011. The patients' data were evaluated with regard to age, gender, etiologic factor of the trauma, type and localization of the injury, and time interval between injury and treatment.
Oral manifestations may be the first sign of Langerhans cell histiocytosis.
Oral Health Prev Dent
July 2013
Article Synopsis
- Langerhans cell histiocytosis (LCH) is a rare condition characterized by the abnormal proliferation of Langerhans cells, often seen as a bone lesion, especially in children.
- A case study of a 2-year-old boy demonstrated symptoms like fever, bleeding gums, and a rash, along with severe bone loss around his teeth, prompting a gingival biopsy.
- Although the exact cause of LCH is unknown, it may be linked to environmental factors and viruses like Epstein-Barr, and oral symptoms might be the first signs of the disease.
Objective: The aim of this study was to evaluate the accuracy of Demirjian's method in estimating the dental age in Turkish children and to estimate the validity of Demirjian's standards for the studied population.
Materials And Methods: Panoramic radiographs of 756 northwestern Turkish children aged 5-13 years were examined. The new method for dental age estimation for both genders was studied to determine the relationship between dental age, chronological age and Demirjian's scores.
Aims: The aim of this study was to evaluate and to compare the effect of two fluoride varnishes and one fluoride/chlorhexidine varnish on Streptococcus mutans and Streptococcus sobrinus biofilm formation, in vitro.
Study Design: Standard acrylic discs were prepared and divided into groups based on the varnish applied to the disc surface: Fluor Protector, Bifluoride 12, and Fluor Protector + Cervitec (1:1). Untreated discs served as controls.
Background: The goal of this study was to evaluate the behavior of neonatal rat calvarial osteoblast-like cells cultured on different implant surfaces and exposed once or three times to a 660-nm light-emitting diode (LED).
Methods: An LED with a 660-nm wavelength was applied once or three times to cultured cells on standard and modified sandblasted acid-etched surfaces (SLA and SLActive; Straumann, Basel, Switzerland). To analyze the effect of the LED on cell proliferation, numbers, and viability, cells were cultured on titanium discs, and measurements were taken after 72 h.
Purpose: The purpose of this study was to evaluate the total success rates of mineral trioxide aggregate (MTA), ferric sulfate (FS), and formocresol (FC) as pulpotomy agents in primary molars.
Methods: A randomized, split-mouth study design was used in 32 healthy 5- to 7-year-old children with 128 carious primary molars without clinical or radiographic evidence of pulp degeneration. The pulpotomy agents were assigned as follows: Group 1=MTA; Group 2=FS; Group 3=1:5 diluted Buckley's FC; and Group 4=zinc oxide eugenol (ZOE) base.
Article Synopsis
- The study aimed to evaluate how CPP-ACP and APF affect the viability of S. mutans bacteria, biofilm structure, and the element content of hydroxyapatite (HA) surfaces.* -
- HA discs were treated with CPP-ACP, APF, and a combination of both, then exposed to saliva and S. mutans to assess bacterial growth, biofilm structure using CLSM, and elemental changes using EDS.* -
- Results showed that both APF and the CPP-ACP+APF groups had significantly lower bacterial counts than the control, but no significant differences in the elemental composition of HA surfaces were found, except for increased fluoride in the APF group.*
There are few reports on treatment of necrotic pulps with mineral trioxide aggregate (MTA) for apexification. Five immature teeth with necrotic pulps were treated with the use of an apical plug of MTA for apexification. All teeth were central incisors that had premature interruption of root development caused by a previous trauma.
