Characterisation of anterior open bite in primary school-aged children: A preliminary study with artificial neural network analysis.

Background: Non-nutritive sucking habits, bottle feeding, and facial hyperdivergency have been suggested as the influencing factors of anterior open bite (AOB). There was inconsistent reporting of prevalence and a gap of knowledge in the literature.

Aim: The aim of this study was to investigate the prevalence of AOB in 7- to 12-year-olds, with a special interest to characterise the determinants of this malocclusion.

Methods: 1756 children, aged from 1 to 33 months (755 females and 1001 males) had been previously examined for the timing of deciduous tooth emergence and their weights and heights measured. Children were categorized into weight and height groups (underweight, normal, overweight, short stature, normal and tall stature).

Mesiodistal and faciolingual diameters of the permanent teeth in a Jordanian population.

Objectives: This study aimed to provide, for a Jordanian population, the first norms of the faciolingual diameters of the permanent dentition and the mesiodistal diameters of the second molars and to provide and review previously published data on the mesiodistal diameters of the permanent teeth up to the first molars in order to investigate any secular trends.

Design: Mesiodistal and faciolingual diameters of the permanent teeth were manually measured on 204 archival pretreatment study casts of adolescents (80 males and 124 females) aged 11-18 years. SPSS (version 16) was used to generate descriptive statistics and investigate the statistically significant differences between right and left sides and between sexes.

Timing of clinical eruption of third molars in a Jordanian population.

Objectives: This study aimed at providing the first standards on the timing of third molar eruption in Jordanians.

Methods: A total of 571 healthy Jordanian adolescents and young adults aged 15-27 years (275 males and 296 females distributed into one-year age groups) were clinically examined for third molar eruption. Presence of four clinical eruption stages from crown emergence to full eruption were counted and expressed each as a frequency relative to the total of participants within a given age group.

The relationship between body mass index and periodontitis among postmenopausal women.

Background: Periodontitis and overweight/obesity prevalence are both increasing worldwide. Overweight/obesity has been suggested as a risk factor for developing periodontitis. The aim of this study was to determine the association between obesity and periodontitis among postmenopausal Jordanian women.

Studying the relationships between the outlines of the face, maxillary central incisor, and maxillary arch in Jordanian adults by using Fourier analysis.

Statement Of The Problem: The outline shapes of the dental arch, face, and tooth are esthetic factors used to determine the proper form of artificial teeth when selected for artificial prostheses.

Purpose: The purpose of this study was to investigate the quantitative relationships between the outlines of the face, the maxillary central incisor, and the maxillary arch by using Fourier analysis.

Material And Methods: Frontal facial photographs and irreversible hydrocolloid impressions of the maxilla were obtained from 200 young, dentate individuals (100 men, 100 women) ages 22 to 28 years.

Timing and sequence of emergence of deciduous teeth in Jordanian children.

Objective: The aim of this study was to provide the timing and sequence of deciduous tooth emergence in a sample of Jordanian children.

Design: A total of 1988 (885 female and 1103 male) children aged from 1 to 45 months recruited from nursery schools and child and maternity health centres in the northern, middle and southern regions of Jordan underwent a dental examination for the detection of deciduous tooth emergence. Children were categorized into 15 3-month-apart age groups.

Tooth shade measurements under standard and nonstandard illumination and their agreement with skin color.

Purpose: The purpose of this study was to examine the relationship between skin color (shade) and tooth shade under standard and nonstandard illumination sources.

Materials And Methods: Four hundred Jordanian participants (200 males, 200 females, 20 to 50 years of age) were studied. Skin colors were assessed and categorized using the L'Oreal and Revlon foundation shade guides (light, medium, dark).

Level of education and gender-specific self-reported oral health behavior among dental students.

Purpose: To identify the oral health attitudes/behaviour among dental students in Jordan, and analyse the variations in oral health attitudes based on gender and level of education.

Materials And Methods: Out of the 653 registered dental students at the faculty of dentistry, 580 students (455 females and 125 males, mean age = 20.1 ± 1.

Ciprofloxacin-induced antibacterial activity is reversed by vitamin E and vitamin C.

In the present study, we investigated the possible involvement of oxidative stress in ciprofloxacin-induced cytotoxicity against several reference bacteria including Pseudomonas aeruginosa ATCC 27853, Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 29213, and clinical isolate of methicillin-resistant Staphylococcus aureus (MRSA). Oxidative stress was assessed by measurement of hydrogen peroxide generation using a FACScan flow cytometer. The antibacterial activity of ciprofloxacin was assessed using the disk diffusion method and by measuring the minimum inhibitory concentration (MIC).

Polymorphisms in sequence of permanent tooth emergence: a cross-sectional study on Jordanian children and adolescents.

Objective: This study aimed at providing the norms of polymorphic gender- variation in the sequence of permanent tooth emergence in Jordanian children and adolescents.

Materials And Methods: A total of 2650 Jordanian children and adolescents (1232 males and 1418 females) aged 4-16 years were examined for permanent tooth emergence. By counting the cases of present-absent and absent-present across all possible intra-arch tooth pairs, the frequencies of sequence polymorphisms were calculated and expressed as percentages in and arch-specific matrices.

Variation in time of emergence of permanent teeth among urban and rural Jordanian school children.

Objective: To investigate the variation in time of permanent tooth emergence between urban and rural Jordanian school children.

Methods: In this observational cross-sectional study, 1900 pupils at urban schools, and 772 at rural schools aged 5-16 years in both genders were examined for emergence of permanent teeth at different urban and rural primary schools and kindergartens in Jordan between March and June 2010. Probit analysis was used to estimate the median age of emergence per permanent tooth.

Timing and sequence of emergence of permanent teeth in the Jordanian population.

Objectives: Population-specific standards of tooth emergence are essential resources for various fields of clinical and forensic dentistry. To date, such standards have not been provided for the Jordanian population. This study aimed at providing the timing and sequence of emergence of the permanent dentition in the Jordanian population.

Delineation of facial archetypes by 3d averaging.

The objective of this study was to investigate the feasibility of creating archetypal 3D faces through computerized 3D facial averaging. A 3D surface scanner Fiore and its software were used to acquire the 3D scans of the faces while 3D Rugle3 and locally-developed software generated the holistic facial averages. 3D facial averages were created from two ethnic groups; European and Japanese and from children with three previous genetic disorders; Williams syndrome, achondroplasia and Sotos syndrome as well as the normal control group.
