Translation and Validation of the Malay Version of Oral Health Impact Profile for Temporomandibular Disorders

ABSTRACT@#Most prior oral health-related quality of life (OHRQoL) research concerning temporomandibular disorders (TMDs) had utilised generic OHRQoL measures. This study aimed to translate and validate the Malay version of Oral Health Impact Profile for TMDs (OHIP-TMDs), a TMDs-specific OHRQoL tool, for use in Malay literate populations. The translation and cross-cultural adaptation of the OHIP-TMDs into the Malay language were implemented according to the international guidelines. A convenience sample of 243 subjects completed the Malay OHIP-TMDs (OHIP-TMDs-M) as well as the Malay Short Oral Health Impact Profile (S-OHIP-M), Global Oral Health ratings (GOH-M) and Fonseca Anamnestic Index (FAI-M). The OHIP-TMDs-M was re-administered to a subset of 40 subjects after two weeks for test-retest reliability. Concurrent, convergent and discriminative validity were assessed using Spearman’s rank correlation, Kruskal Wallis and Mann-Whitney U tests with significance level set at p < 0.05. The OHIP-TMDs-M was found to have excellent internal consistency (Cronbach’s alpha = 0.98) and test-retest reliability (intraclass correlation coefficient = 0.99, p < 0.001). A strong and positive correlation with S-OHIP-M (rs = 0.74) was observed, and OHIP-TMDs-M scores differed significantly between subjects with disparate GOH-M ratings (p < 0.001). Furthermore, the OHIP-TMDs-M was able to discriminate between subjects with and without TMDs. The OHIP-TMDs-M was found to have excellent reliability and good validity. It is a promising tool for assessing TMDs-specific OHRQoL in Malay literate populations.

Maxillofacial Trauma of Paediatric Patients: University of Malaya Experience

@#This study aimed to determine the incidence, aetiology, types of injury, management and the outcomes of the treatment of maxillofacial trauma among paediatric patients treated in Faculty of Dentistry, University of Malaya. A retrospective study (2005-2015) was carried out which involved retrieving past records (manual/electronic form) of paediatric patients (under 16 years old) who presented with maxillofacial trauma. Data collected was organized using descriptive statistics with SPSS version 12.0.1. The total number of patients was 120 but only 93 had complete records. The ratio of boys to girls was 2:1. The main cause of injury was falling (54%) followed by motor-vehicle accident (MVA) (42%), assault (3%), and sport (1%). The total count of soft tissue injury only was about 41% while 59% presented with maxillofacial fracture. Midface were the most common fracture occurred followed by mandibular fractures. Both fractures were mostly managed by open reduction and internal fixation (ORIF) using non-resorbable plates except for condylar fractures which were mostly managed conservatively. In conclusion, the incidence of maxillofacial trauma in children increased within the time frame of this study. The most common aetiology was fall. Hard tissue injury accounting for most of the cases whereby midface was the most common site involved. ORIF was the treatment of choice for most of the fracture cases except for condylar fractures (conservative management). All patients had achieved reasonable outcomes postoperatively in terms of form and functions.
