Anterior crossbites would normally require early intervention, especially when associated with mandibular displacements. The intervention would usually commence in children around the age of eight and nine, where treatment could be a challenge at this age. Therefore, a simple and quick treatment to this malocclusion would be desirable. This case series illustrates two cases of anterior crossbite with a functional shift that were successfully corrected using a simplified fixed technique, which involved a short-span nickel-titanium (Ni-Ti) aligning round archwire, composite resin and glass ionomer cement (GIC).

Implant prosthesis is a popular treatment modality but it is not complication free. This article discussed the management of a cemented, all-ceramic implant crown in the maxillary anterior region that had veneering ceramic fracture after three years in function. A screw-retained prosthesis was prescribed to avoid the show of the screw access channel on the incisal edge of the crown. This was achieved by changing the location of the screw hole using the angle screw channel that overcame the angulation issue.

Good denture hygiene is crucial for the prevention of various periodontal diseases, dental caries and dental stomatitis, which can give rise to a negative impact on the general health of denture users. A comparison exercise was conducted, to determine the effectiveness of information on denture care, provided by different groups of dental personnel. A self-administered and structured questionnaire was distributed to patients who attended Hospital USM’s dental clinics, from 2014 to 2019 based on the attendance register of the clinic. The denture hygiene status of 100 participants was assessed during the interview session. The results derived through the questionnaire revealed that 100% of the respondents, who received both verbal and written instructions, practiced good dental hygiene. It was observed that the most effective instructions received by the respondents were delivered by the dental specialists. Respondents, who clean their dentures with denture cleaning tablets, soap, or denture cleaning paste, were observed to possess better denture hygiene than those who do not. Also, respondents who visit their dentists once every six months for routine dental examinations boasted a higher percentage of good denture hygiene (81.8%). A positive association was perceived, between knowledge and the status of denture hygiene.

Orofacial odontogenic infection, although arises from dental origin, can extend into the facial spaces and lead to debilitating complications. This study analysed the clinical pattern and management of orofacial odontogenic infection in a tertiary hospital namely Hospital Raja Permaisuri Bainun in Perak, Malaysia. We investigated any associations between socio-demographic factors, diabetic, comorbidities, smoking, pregnancy, antibiotic resistance, number and type of space infected towards prolonged hospital stay. All adult patients with orofacial odontogenic infections treated by Department of Oral and Maxillofacial Surgery from 2014 to 2018 were included. Clinical patterns were evaluated. Statistical analysis was performed to measure various variables towards prolonged hospital stay. A total of 154 patients (78 male, 76 female) were included in this study with mean age of 37.95 ± 14.9 years. Key factors of orofacial odontogenic infection requiring admissions were swelling, pain, trismus, odynophagia, reduced oral intake, raised floor of mouth and dyspnea. Among inpatients, three factors were significantly associated with prolonged hospital stay, namely antibiotic resistance, multiple space and secondary space infection. Local prevalence data was reported. Pus culture and sensitivity tests were recommended for all inpatients with multiple space and secondary space involvement, in order to rule out antibiotic resistance and to improve recovery rate.

The goal of this study was to investigate differences in alkaline phosphatase (ALP) levels in young and old rabbits after administering the soybean isoflavone genistein during orthodontic tooth movement. Twelve rabbits were used and assigned to four groups (n = 3); OG (old rabbits), OGS (old rabbits + soybean), YG (young rabbits), and YGS (young rabbits + soybean). The rabbit mandibulary incisors were distalised using a nickel-titanium open coil spring (50 g force). Genistein was administered from the initial orthodontic force delivery until day 21, at a dose of 1.2 mg/kg BW once a day. ALP levels (U/mg) were measured on days 1, 7, 14, 21 after orthodontic force delivery using a UV-Vis 6300 spectrophotometer at a 405 nm wavelength. The results were analysed by one-way analysis of variance followed by Tukey’s Honest Significant Difference (HSD) test (p < 0.05). The ALP levels between the young and old age groups were significantly different. ALP levels were highest in the YGS group, and significantly lowest in the OG group (p < 0.05). Moreover, the ALP level of the OGS group was significantly higher than that in the OG group (p < 0.05). In conclusion, daily consumption of soybean isoflavone genistein could enhance ALP levels during orthodontic tooth movement, particularly in older rabbits.

This study aims to evaluate the optimum duration of flushing dental unit waterlines (DUWLs) in Universiti Sains Islam Malaysia (USIM) dental polyclinics for removal of heterotrophic bacteria. Water samples were obtained from triple air syringes at each dental chair from oral surgery clinic, outpatient clinic and polyclinic 17 at Faculty of Dentistry, USIM after 16 and 64 hours of not operating the dental units as baseline samples. This is followed by sampling after continuous flushing at 30 seconds, 1 minute, 2 minutes and 3 minutes of flushing duration. The levels of heterotrophic plate count (HPC) for each flushing duration were determined by quantification of colony forming units (CFUs) after cultivation of samples on plate count agar (PCA), R2A agar and 5% sheep blood agar (SBA). Statistically, there was no significant reduction in CFUs of HPC for all flushing duration compared to baseline (P > 0.05) with the most notable HPC reducing level after 1 minute and 3 minutes of flushing DUWLs. However, HPC level at USIM dental clinics is still exceeding the recommendation by Centers for Disease Control and Prevention (CDC) which should be less than 500 CFU/mL. The existing method of controlling DUWLs contamination in USIM dental clinics is only by flushing DUWLs 1 minute every morning prior to dental treatment as recommended by Malaysian Dental Council (MDC) without the use of chemical germicides. Thus, the flushing method alone is not reliable to reduce the number of microorganisms in the DUWLs.

Soft palate tumors pose the challenge during reconstructive and rehabilitating procedures. Surgical resection of these tumors leads to velopharyngeal insufficiency (VPI). The primary effects of VPI are hypernasality and air-flow escape, while the secondary effects are abnormalities in speech articulation. Surgical revision along with speech therapy is a common approach to the treatment of VPI. Prosthetic management by means of speech aid prosthesis helps to reduce resonance, nasal emission and consonants errors. This clinical report describes the different stages of rehabilitation of velopharyngeal insufficiency defect following resection of malignant melanoma of left posterior alveolar ridge and soft palate. The speech aid prosthesis helped to rehabilitate the velopharyngeal insufficiency defect and aided in the diagnosis of extent of speech function improvement by perceptual and objective methods.
