The prevalence of Brodie bite in untreated orthodontic patients in Nigeria.

Objective: The Brodie bite (BRB) is a rare posterior crossbite affecting the transverse occlusal relationship with the palatal cusps of the upper molars, biting into the vestibule and outside the buccal cusps of the lower molar teeth. The BRB is a highly challenging orthodontic problem and is an extreme form of scissors bite. Patients with this problem present with facial deformity and inability to chew on the affected side.

Cultural constraints in the use of dental implants and orthodontic mini-implants in Benin City, Nigeria.

Background: Dental implants and orthodontic mini implants or temporary anchorage devices (TAD) have been used for tooth replacement and as adjuncts to orthodontic treatment in anchorage control and retraction of segments of teeth respectively. They are manufactured from various materials with titanium being the currently used material. The patients in our environment have diverse cultural acceptances and constraints with some prohibiting the use of certain materials in their oral cavity.

Prevalence of traumatic dental injury to the anterior teeth in children attending paramilitary and nonparamilitary schools in Nigeria.

Objective: The objective of this study was to determine the prevalence of traumatic dental injuries (TDIs) in the anterior teeth among children attending paramilitary and nonparamilitary schools in Benin City, Nigeria.

Materials And Methods: A multistage sampling technique was used to select children aged 8-12 years with a previous history of trauma to the orofacial region. A self-administered questionnaire was then applied, and each participant was examined clinically.

Visual acuity, safe/unsafe practices and self-reported road traffic crash experiences among commuter bus drivers from two motor parks in Lagos, Nigeria.

Background: The sella turcica is an important anatomical landmark and reference point in orthodontics with many studies identifying shape and morphology for different populations. The aim of this study was to evaluate sella turcica shapes in skeletal classes I, II and III orthodontic patients in Benin City, Nigeria.

Study Design: This study was carried out at the Orthodontic Unit of the University of Benin Teaching Hospital, Benin City, Nigeria.

Comparing the 810nm diode laser with conventional surgery in orthodontic soft tissue procedures.

Aim: To compare the use of the 810nm diode laser with conventional surgery in the management of soft tissue mucogingival problems associated with orthodontic treatment.

Methods: Orthodontic patients requiring different soft tissue surgical procedures were randomly assigned to receive conventional surgery or soft tissue diode laser, (wavelength 810 nm).

Main Outcome Measures: Parameters documented include the type of anaesthesia used, intra and post operative pain, bleeding, the use of scalpel and sutures.

Prevalence and factors associated with anterior open bite in 2 to 5 year old children in Benin city, Nigeria.

Background: Anterior open bite is said to exist when there is an actual vertical gap between the upper and lower incisors with the teeth in centric occlusion. This could occur in the anterior or posterior region, and may be attributed to the supra eruption of the posterior teeth or the infra eruption of the anterior teeth and it is common in both adults and children.

Objective: To evaluate the prevalence of anterior open bite (AOB) in 2 to 5 -year -old children and the aetiological factors responsible for it.

Reimplantation of avulsed dry permanent teeth after three days: a report of two cases.

Two cases of reimplantation of avulsed teeth that occurred after 72 hours are reported. The two patients were male and female aged 13 and 24 years, respectively. The avulsed teeth were not placed in any storage medium for the duration they were out of the mouth and there was no periodontal ligament remaining on their root surfaces before the reimplantation.

Nickel chromium brackets and its effect on the oral microflora.

Unlabelled: Nickel chromium brackets are the most common type of fixed orthodontic appliance used in our environment and may alter the oral microflora.

Aim: This study aimed to determine the effect of nickel chromium brackets in orthodontic treatment on the oral microflora and to compare with a control group of dental students.

Method: Thirty-eight randomly selected participants were divided into two groups.

Feeding intervention in cleft lip and palate babies: a practical approach to feeding efficiency and weight gain.

Using a disposable syringe to feed 1-14-week-old babies with cleft lip and palate (CLP) was studied. 57 CLP babies were randomly divided into: syringe-fed (intervention) and cup-and-spoon-fed groups and compared with 55 normal breast- or bottle-fed babies. Differences in weight gained from birth to 6, 10 and 14 weeks were compared.

Assessment of malocclusion in pre-school children in Benin City using the incisor classification of malocclusion.

This study was aimed at analysing the incisors as a means of classifying malocclusion in pre-school children Incisal classification is not common but is a simple and reliable means of assessing malocclusion, especially in pre-school children. The classification is mainly used to describe the incisal relationship of cases in verbal and written communication between clinicians. Angle's classification holds when the first permanent molars are in place, but in the pre-school child, between the ages of 2-4 years, the first permanent molars may not have erupted.
