Traumatic dental injury (TDI) to primary teeth is common in childhood and often not given sufficient attention by parents. Many parents think primary teeth are only transient before permanent successors replace them. One of the serious consequences of TDI to primary teeth is tooth dilaceration of the permanent successor teeth. Luxation injuries, su...

The correction of rotated malpositioned tooth/teeth into the dental arch alignment in the mixed-dentition is often a challenging task for paediatric dentists. Failure in addressing this issue can bring about detrimental effect to the developing dentition and increases the probability of a complex orthodontic treatment in later years. Factors such a...

Uncaria gambirextracts consist of catechins thathave been shown to possess anti-inflammatory and antibacterial properties. This property shows some clinical potential but the cytotoxicity of the extracts found in Malaysia has not been reported. Hence, the study aimed to determine the cytotoxicity of Malaysian Uncaria gambir extracts toward fibrobla...

Objective: To assess the relationships of socio-demography, self-reported oral health status, and behaviour with oral health literacy (OHL) among adults.

Dens evaginatus is a dental developmental anomaly that arises due to the folding of the inner dental epithelium that leads to the formation of an additional cusp or tubercle on the occlusal surface of the affected tooth. This accessory tissue projection may carry with it a narrow and constricted pulp horn extension. Occasionally, the tubercle easil...

Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of problems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite correction in young children is treatment compliance. In most cases, poor compliance is due to the u...

Complicated crown-root fractures account for a small percentage of traumatic dental injuries seen in children; however, management of these injuries can be very challenging to clinicians. Factors such as complexity of the injury, patient’s age and dentition stage, patient’s cooperation, and parental demands may have some bearing on the type of trea...

The present study compared and evaluated the shear bond strength (SBS) of two types of glass ionomer cement (GIC), Riva Self Cure HVTM (SDI Ltd., Victoria, Australia) and GC Fuji IX GP EXTRATM (GC America Inc., Alsip, USA) with and without the use of Riva Bond LCTM (SDI Ltd., Victoria, Australia), a lighted cured resin-modified glass ionomer cement...

This in-vitro study aimed to evaluate and compare the marginal leakage and penetration ability of a moisture-tolerant (Embrace WetBondTM) and a conventional (ClinproTM) resin-based sealants under three different enamel surface preparations (acid etched, acid etched and saliva contaminated and bur preparation and acid etched). One hundred and twenty...

Trauma to the permanent dentition is common in children and adolescents. Almost two-third of these traumas involve a single anterior tooth. However, multiple dental injuries are often seen in high-velocity accident or sport related fall. These injuries can bring about serious damage to the tooth supporting structures and subsequent complications if...

Bullous impetigo is a highly contagious skin infection commonly affecting children due to epidermolytic toxins of bacteria Staphylococcus sp. This presentation described a case of a 3 year-old Indian girl with bullous lesion around the peri-oral region. The lesion was initially thought to be of viral origin and was treated symptomatically. However,...

BCD syndrome is a rare birth syndrome characterised by cleft lip and palate, euryblepharon with/without limb anomalies, ectropion of lower eyelids and hypertelorism. The dental anomalies include cone shaped microdontic teeth and oligodontia. Different combinations of these signs have been found sporadically in patients. This syndrome is also known...

This was a retrospective study that looked at the prevalence, characteristics, gender predilection and common problems associated with supernumerary teeth found in children at the Paediatric Dental Clinic, Faculty of Dentistry, National University of Malaysia (UKM). Four hundred ninety clinical records of children with relevant radiographs with a m...

Presence of accessory cusp on the occlusal surface of a tooth may occasionally pose problems to dentists'. Although its presents may not be a cause for alarm in most instances, nevertheless it can lead to serious consequences if it is damaged. This report describes a rare finding of bilateral central accessory cusp seen on the occlusal surface of b...

Complicated crown-root fractures are rare and often need complex treatment planning. This paper describes a simplified treatment option for a complicated crown root fracture that minimally encroached into the biologic region in a growing child without the need for surgery or orthodontic treatment.

The aim of study was to determine the preferences of dentists' attires among primary school children. This is a cross-sectional descriptive study involving 50 primary school children. This study was conducted by using three sets of pictures representing dentists' attires without overcoat (Set A), with overcoat (Set B) and combination of with and wi...
