Aim: With the increased use of cone beam computed tomography (CBCT) scans in orthodontic diagnosis and treatment planning, validation of using radiographic images obtained from CBCT instead of multiple conventional radiographs is needed. Hence, the present study was designed to assess the differences between cephalometric measurements taken from manual tracings (MT), digitized lateral cephalograms (DLC) and CBCT lateral cephalograms scansMethods: Conventional lateral cephalograms and CBCT scans from ten subjects from departmental archives were used to assess the three methods: manual tracings, digitized lateral cephalograms, and CBCT lateral cephalograms. Seventeen measurements were evaluated and retraced after a 7-day period. The intra examiner errors was assessed using the paired t test and Dahlberg formula. The Pearson correlation test and ANOVA test evaluated the differences between the methods.Results: Most of the measurements had intra-examiner reliability in all three methods. Measurements were significant among methods were Y-axis, U1-Apog (degree and mm), U1-NA, L1-NB (degree and mm), L1-Apog, and interincisal angle.Conclusion: All three methods proved to be reliable and reproducible with minimum error in the measurement of lateral cephalograms. The CBCT scan, advised for complex cases, can be used to generate lateral cephalogram images, which may reduce the need for multiple radiographs, thereby reducing radiation exposure and cost.

Aim: Quality management in orthodontics is a complex issue which aims at providing high quality services to patients. Development of a well established quality control policy according to regional characteristics and socio-economic features of the consumers, is of great importance. However, there is also an inevitable need for careful supervision regarding the implementation of the quality control program. This study is to evaluate and improve standards in removable orthodontic treatment.Materials and Methods: Data was retrieved from students, patients, orthodontists and technicians filled the relevant fields of questionnaires. The patients were chosen from those who had passed their second follow up session. The following health service modules were assessed in the questionnaires: "The pre-admission phase for patients", "The pmcass of admission". "The treatment, the follow up and the retention phase", and "The laboratory".Results: The results were analyzed in two categories; the patient related questions (clinic) including modules from entrance to dismissal and the technician related questions (appliance construction). The pattern of the answers in the first category was: 8.1% "Very poor", 12.7% "Poor', 32.5% "Moderate", 48.8% "Good" and 0% "Very good". The second category of questions yielded the following pattern of response: 16.1% voted "Very poor", 61.2% voted "Poor" and 12.6% voted "Moderate", 9.6% "Good" and 0% "Very good". In general, the majority of participants (38.4%) marked the answer choice "Good".Conclusions: Generally, the treatment provided for patients seemed to be of "good" standard. However, further attention has to be devoted to laboratory-related aspects of Orthodontic services.
