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.

Pilomatrixoma is an uncommon benign tumour arising from the matrix and inner sheath of a normal hair follicle as well as hair cortex. It is usually presented as a superficial, solitary, firm mass which is asymptomatic and slowly growing. It accounts for about 0.2% of all routine skin specimens and may poses a diagnostic challenge as it may resemble other common benign lesions found in the head and neck region. We report a case of a 33-year old men presented to us with a pilomatrixoma of the right cheek, surgical management and histological findings.
