“…Generally, the desired mapping accuracy can be controlled simply by altering the focal length of the lens, the object distance and the pixel resolution of the CCD of the camera. Relative object space accuracy of 0·5 mm or higher can be achieved using stereo or multiple photographs routinely (Newton, 1974; Burke et al., 1983; Hay et al., 1985; Deacon et al., 1991).…”

Photogrammetry is a non‐contact, high‐accuracy, practical and cost‐effective technique for a large number of medical applications. Lately, three‐dimensional (3D) laser scanning and digital imaging technology have raised the importance of digital photogrammetry technology to a new height in craniofacial mapping. Under the support of the Eighth Malaysian Development Plan, the Ministry of Science, Technology and the Environment (MOSTE) Malaysia allocated a grant to establish procedures for the development of a national craniofacial spatial database to assist the medical profession to provide better health services to the public. To populate the database with normal and abnormal (malformation, diseased and trauma and burn victims) craniofacial information, it is necessary to evaluate the technology needed to capture the essential data of craniofacial features. The paper provides a discussion on the basic features of the spatial data and the data capture techniques. Both are needed for the establishment of a national spatial craniofacial database. The discussion includes a brief review of the current status of two selected high‐accuracy craniofacial spatial data capture techniques, namely, digital photogrammetry and 3D laser scanning. The paper highlights a system which has been developed for a Malaysian craniofacial mapping project. Laboratory tests with mannequins showed that the photogrammetric and 3D laser scanning system could achieve an accuracy exceeding the design specification of ±0·7 mm (one standard deviation) for all the measured craniofacial distances. However, tests with two living subjects showed that the accuracy was in the order of ±1·2 mm because of facial movement during data capture.

Objectives: To compare the three non-steroidal anti-inflammatory agents (NSAIDs) diclofenac potassium, etodolac and naproxen sodium in relation to pain, swelling and trismus following impacted third molar surgery. Study Design: The study was a randomized and a double-blinded study which included 42 healthy young individuals with impacted third molars and bone retention. Patients were randomly assigned to 3 groups (n: 14) to which diclofenac potassium, naproxen sodium and etodolac were administered orally an hour before the operation. Impacted third molars were surgically extracted with local anaesthesia. Visual analog scales (VAS) were used to assess the pain in the 6th, 12th hours and on the 1st, 2nd, 3rd, 5th, and 7th days postoperatively. Swelling was evaluated using ultrasound (US) and mouth opening (trismus) was measured with a composing stick pre and post operatively on the 2nd and 7th days respectively. Results: Regarding pain alleviation, diclofenac potassium was better than naproxen sodium and naproxen sodium was better than etodolac but these differences were not statistically significant. US measurements showed that the swelling on postoperative 2nd day was significantly lowest with diclofenac potassium as compared to others (p= 0.027) while naproxen sodium and etodolac acted similarly (p=0.747). No difference was noted regarding trismus in any of the groups. Conclusions: NSAIDs (diclofenac, naproxen and etodolac) are somehow similarly effective for controlling pain and trismus following extraction of mandibular third molars but diclofenac potassium surpasses others in reduction of swelling. Key words:Diclofenac potassium, naproxen sodium, etodolac, impacted third molar surgery, pain, swelling, trismus.

“…There is controversy in the orthodontic literature regarding the correlation between craniofacial skeletal and soft-tissue profile form (Denis & Speidel, 1987;Bloom, 1961;Burke, 1983;Savara, 1965). For instance, although stereophotogrammetric (Savara, 1965;Burke, 1983;Peck & Peck, 1995), computed tomographic (Marsh & Vannier, 1983;Moss et al, 1987) and cephalometric studies (Riedel, 1950;Tweed, 1944) have indicated soft-tissue profile form is markedly influenced by orthodontic tooth movement and or orthognathic surgery,…”
