    In this study, we aimed to compare the cusp and crown areas of the maxillary first premolar (PM1), second premolar (PM2), and first molar (M1) in males and females in the Malay population and to formulate sex prediction models. For this purpose, the maxillary posterior teeth of 176 dental cast samples (from 88 males and 88 females) were selected and transformed to two-dimensional digital models using 2D-Hirox KH-7700. Cusp and crown area measurements were obtained using Hirox software by tracing the outermost circumference of the tooth cusps. Statistical analysis included independent t-tests, logistic regression analysis, and receiver-operating characteristic (ROC) curves as well as determination of sensitivity and specificity; analysis was performed with SPSS version 26.0. The significance threshold was set at 0.05. All crown and cusp area measurements were significantly larger in males than in females (p

    Introduction: Hall's technique preformed metal crown (HTPMC) has been used widely by pediatric dentists in developed countries as a new approach for managing decayed primary molars without local anesthesia, caries removal, and tooth preparation. Currently, inadequate information is available regarding the implementation of this technique (HTPMC) in Malaysia. This study is aimed at evaluating the implementation of HTPMC by Malaysia's pediatric dentists and identify the co-occurrence frequencies of the HTPMC implementation with the respondents' demographic profile.

    Materials and Methods: A cross-sectional questionnaire-based research was conducted among 65 pediatric dentists in Malaysia. Online questionnaires were distributed to the pediatric dentists employed at public hospitals (MOH) and universities in Malaysia.

    Result: It was found that over half of the respondents (65.6%) employed HTPMC. The analysis of the co-occurrence network frequency revealed that a high frequency of female pediatric dentists who were within the age group of 31-40 years old had fulfilled their postgraduation overseas and was employed in the university mainly applied HTPMC.

    Conclusion: The application of HTPMC among respondent pediatric dentists in Malaysia was high. However, most respondents considered HTPMC a treatment option only to manage carious primary molar rather than a treatment of choice.
