Background Surgical uprighting and repositioning have been proposed to obtain a correct alignment of unerupted permanent molars. A retrospective clinical study was performed to verify the effectiveness of these techniques. Material and Methods In order for a case to be included in the study, adequate clinical documentation was required, including radiographic imaging before and after therapy. The degree of inclination of each treated molar was evaluated on pre-operative panoramic radiographs. Results Fifty-two molars were studied. Molar involvement was more frequent in the mandible (45 cases=86.54%) than in the maxilla (7 cases=13.66%). The mean age of patients treated with completely formed molars was 17.28±2.86, while that of patients with incompletely formed molars was 12.89±1.75. The most frequent position was mesio-angular (39=75%) with a mean inclination of 31.61°±12.9° (range 5.57°-61.26°). Disto-angular molars had a mean inclination of -28.84°±6.49° (range -23.79°- -36.16°). Surgical uprighting was performed in 37 cases (71.15%), while surgical repositioning was performed in 15 cases (28.85%). Three cases were lost during the follow-up. The outcome was positive in the remaining 49 cases. Complications occurred in only 4 surgeries (7.69%). Conclusions Surgical uprighting and repositioning are reliable therapeutic solutions for unerupted mandibular molars, with a favorable prognosis.

Objective: To identify which variable, among those related to surgeries, to patients, or to antithrombotic treatments, could be considered as a bleeding indicator, and to analyze effectiveness of the local hemostatic protocols used, incidence of bleeding and healing index, depending on the number of extracted teeth, and patient antithrombotic treatment.Methods: Patients who underwent tooth extractions without interruption or reduction of antithrombotic treatment were prospectively followed. The exact two-tailed Fisher test was used to investigate the relationship between presence/absence of bleeding and type of hemostatic material. The effect of variables on the probability of bleeding and healing index was assessed by means of a multivariate logistic regression.Results: Two hundred and fifty-four procedures were analyzed. The incidence of bleeding was 15.75%. Severe bleeding occurred in only 6 patients (2.34%). The number of involved dental quadrants and pre-surgical antibiotic treatments were found to be positively related with bleeding. The use of vasoconstrictors during surgery resulted in a reduction of healing index scores. Conclusions:Tooth extractions in patients on antithrombotic treatment were found to be free from significant bleeding although the involvement of more than 1 quadrant in the same procedure should be avoided.

Background The aim of the study was to investigate the usefulness of telephone follow-up in preventing post-extraction bleeding and improving wound healing in patients on chronic antithrombotic treatment. Material and Methods A prospective randomized clinical trial was carried out on 256 patients (test group = 128; control group = 128). The exact two-tailed Fisher test and the two-tailed non-parametric Mann-Whitney test were used for statistical analysis. Results The incidence of post-extraction bleeding was 15.6% and there was no difference between test and control groups. However, the study group was significantly, though weakly, associated with the severity of bleeding. Patient satisfaction with post-operative follow-up differed significantly between patients who had and those who did not have post-extraction bleeding. Conclusions Telephone follow-up after tooth extraction may play a role in the prevention of severe post-operative bleeding as well as in monitoring and managing the surgical wound. Key words: Post-operative instructions, patient satisfaction, wound healing.
