Exceptional bone remodeling over composite restoration in the management of external root resorption: A case report.

A 65-year-old Caucasian male was referred to an endodontic specialist practice in a private clinic in December 2019 for the management of an asymptomatic, radiolucent lesion located at the cervical level of the distal root of his right lower first molar, noticed during a routine periapical radiograph. After an accurate evaluation with cone-beam computed tomography (CBCT), the subgingival lesion was diagnosed as a supracrestal external cervical resorption (ECR), with a circumferential spread ⩽90°, confined to dentine without pulp involvement. The lesion was treated with the following sequence: (1) a full flap accessed the ECR, (2) the granulomatous tissue was removed from the root area, (3) the cavity was refreshed and filled with a well-refined and polished resin composite, (4) the flap was sutured at the cemento-enamel junction.

Endodontic Clinical Outcome after Separated Instrument Removal Using a Spinal Needle Technique: A Retrospective Study of Thirty Years of Clinical Experience.

Introduction: Current methods for the removal of separated endodontic instruments (RSI) are not predictable.

Methods: The primary outcome of this retrospective study was to assess the clinical and radiographic success (CRS) of teeth in case of RSI after a 5-year follow-up. Secondary outcomes were to evaluate (1) the effectiveness in RSI and (2) the risk of root fracture after RSI.

Lingual Flap Protection during Third Molar Surgery: A Literature Review.

The purpose of this review was to analyze how the retraction and protection of lingual flap (LF+) could influence the incidence of lingual nerve injury (LNI) during third molar extraction, as compared with protocols that do not involve handling of lingual tissue (LF). A literature review was performed from the "Medline" and "Scopus" medical databases, using the keywords "lingual nerve" and "third molar surgery." From the selected articles, the mean values for transitory and permanent LNI's incidence were elaborated, taking into account the group treated with LF+ technique and the group treated with LF technique.

Repair of teeth with cracks in crowns and roots: An observational clinical study.

Aim: This retrospective observational study investigated the survival rate of teeth with radicular cracks that were restored using composite materials.

Methodology: The study was approved by the Ethical Committee of Sistema Sanitario Nazionale (prot. N°2370CELazio1), Clinicaltrials.

Reaction rate of NaOCl in contact with bovine dentine: effect of activation, exposure time, concentration and pH.

Aim: To determine the influence of activation method (ultrasound or laser), concentration, pH and exposure time on the reaction rate (RR) of NaOCl when in contact with dentinal walls.

Methodology: The walls from standardized root canals in bovine incisors were exposed to a standardized volume of sodium hypochlorite (NaOCl) with different concentrations (2% and 10%), pH (5 and 12) and exposure times (1 and 4min). Two irrigation protocols were tested: passive ultrasonic irrigation or laser activated irrigation with no activation as the control.

[Antibiotic prophylaxis with cefotaxime in gynecological endoscopy].

It is now well known that even short operations of limited scope lower the body's defences by influencing the immune system. As a result this leads to a change in microbial flora which encourages an increase in the number of Gram-negative, aerobic, anaerobic and enterococcal colonies. In order to prevent infective postoperative complications which might occur after endoscopic surgery, the authors suggest using a series of valuable recommendations which are reported in this paper.

[Preliminary study of the use of s. adenosyl methionine in the management of male sterility].

In a preliminary study 10 cases of male sterility were treated with 800 mg/day per os of Samyr-Bioresearch over three months. Increased basal motiligy of spermatozoa was observed in 6 out of 10 cases. The results of the study confirm the value and efficacy of SAM in the treatment of male sterility.

[Clinical study of the use of a new tri-phasic pill].

The paper reports the results of a study to assess the contraceptive efficacy of a new triphasic pill (Trinovum - Cilag AG). The pill was administered to 50 women aged between 18 and 41 years for 12 months, giving a total of 600 menstrual cycles. Data confirm the value of this pill which ensures excellent contraceptive efficacy and is well tolerated by patients with very few adverse effects.

[Respiratory distress syndrome in premature births].

The paper reports the results of a study of respiratory distress syndrome in premature birth, one of the most common and important forms of respiratory disorders affecting neonates during the first days of life. One hundred and fifty-six premature births from 1 January 1986 to 30 June 1988 were included in the study. From an analysis of results it emerges that there is a lower incidence of respiratory distress syndrome in both vaginal deliveries and cases treated with Ambroxol.

[Uterine fibromyoma in pregnancy].

Data are reported relating to the study of 100 pregnant women, aged between 30 and 49 years old, effected by one or more fibroma nodules on the body of the womb. From an analysis of results, it appears that appropriate obstetric care can significantly reduce the risk of both maternal and fetal complications.

[Uterine rupture in modern obstetrics].

The paper reports 18 cases of womb rupture observed in the Institute of Gynecology and Obstetrics at the University of Turin from April 1978 to June 1988. Following an analysis of the data relating to the above cases, the paper concludes that in order to reduce the incidence of womb rupture it is important to hospitalize high-risk patients preferably before the start of labour so as to intervent using caesarian section.

[Inflammation of the uterine corpus: endometritis].

In industrialised countries endometritis is a problem which represents an increasing risk to personal health and to society. In almost all cases the inflammatory process which affects the uterine mucosa forms part of a more generalised infection which involves the entire internal genital system (PID). The most important problem associated with pelvic phlogosis is increased sterility, a greater number of ectopic pregnancies and chronic pelvic pain.

[Effectiveness of povidone-iodine in the treatment of non-specific vaginitis].

Thirty-two cases of aspecific vaginitis treated with a ready-to-use providone-iodine solution are reported. Results were highly positive with regard to the efficacy and safety of the treatment.

[Hormonal contraception using estroprogestins].

Today the estroprogestagen pill is the most valid method of contraception given that its benefits far outweigh its risks. The paper stresses the importance of a thorough anamnestic, clinical and laboratory examination so as to obtain correct and safe steroid contraception. The efficacy and excellent tolerance of the combined method currently make it the most widespread form of oral contraception.

[Perinatal mortality in placental insufficiency].

The review of 55 cases of placental failure and the results obtained reveal a 54% mortality rate.

[Endoscopic treatment of polycystic ovary syndrome. Preliminary data].

Four women suffering from polycystic ovary syndrome recalcitrant to routine ovulation inducers have been submitted to electro-cauterization and ovarian resection. Hormonal changes after 24 hours and the incidence of ovulatory cycles in the 6 months subsequent to the execution of these surgical techniques are reported.

[Use of orgotein in the treatment of reactive damage to the use of high-energy radiation].

A study has been carried out on 62 patients submitted to pre- and postoperative X-ray treatment, evaluating tolerance and effectiveness of orgotein administered i.m. The therapeutic results obtained may be considered very satisfactory.

[Role of viral infections in the genesis of dysplasias of the uterine cervix].

A study of 80 cases of dysplasia of the uterine cervix showed the coexistence of HPV infections in 52 cases. This association (65%) shows the important role played by the human papilloma virus in the genesis of cancer of the cervix.
