Conventional Linear ToInography lnaging for Mandibular Implants TrealmentRadjographic examination has a very important role in dental implant treatment, including preoperatile olanninc and inua operalive and postoperativ€ assessm€nt ln preoperative planning, radiographi€ e>,aminatron has an abtir) to vGualize ctrlical mandibular anatomic organ such as mandibular foramen, mandibular canals, and mental foramina, which will guide the choice of implant length' diameter' and Dosition. Besides. it also can r€veal variation of qualitv and quantitv of the jaw bone Radiographic examination for postoperative assessment of dental irnplant is usually addressed for evaluation of implant position. Developmentand applicarion modem imaging modalities in denro-ma\illofacial radiolog/ have very inportanl role ior better accuracy and more comprehensjve dental irnplant tr€atmmt One of modem radiographlc imaging tecbnique for this purpose is conventional linier tomography This modality yields vtsuaization of bone qLraliry and quanrity in high derail and accuncy, including bone condirion in buccallineual dimension.

Alteration of Temporomandibular joint is part of the stogmatonagti. The prevalence of joint disorders is 10-70% most cases have lost mandibular molars. This research will the alteration of articular eminence inclination on temporomandibular joint between patients that loss the unilateral mandibular posterior teeth and patients with mandibular posterior teeth using panoramic x-ray. Analytic research cross-sectional study design. Data analysis was performed using an independent T-test with p-value = 0.05. T will be count as the average deviation of EA (eminensia artikularis) angle with sig value (P-Value) of 0,009 less, out of 0,05 or α

The Thermafil obturation technique is relatively new. The working time and materials used in this technique are more efficient so that the thermafil obturation technique is more environmental-friendly. The objective of this study was to determine the differences of the root canal leakage between the techniques of thermafil and the lateral condensation root canal fillings. Seventy extracted single teeth straight roots were prepared with step back techniques. The diameter of the apical foramen were standardized by using number 15 file and the length of the teeth were reduced by 1 mm. The root canals were prepared until no.40 as MAC and the last file was no.55. The teeth were randomized and filled with the guttaperca thermafil and lateral condensation technique. The calculation of the leakage was measure by microscope with 30 times enlargement, and statistically analized using the Chi Square test of P<0.05. The study showed that the leakage of the guttapercha lateral condensation technique was not better than guttapercha thermafill technique. The thermafill had more leakage distance than lateral condensation technique.
