* Methods: * The DRGA follow-up visit recommendation was changed from six weeks to two weeks postsurgery. Attendance rates for recall exams were evaluated before and after implementation with 17 months follow-up (n equals 544). Attendance was then compared by age, special health care needs, foster care status, and caries recurrence.

* Results: * The intervention improved compliance with DRGA follow-up for all ages (P<0.001) and six-month recall visits for ages zero to five (83.3 percent of cases, P=0.001). Patients were more likely to return for any visit within 17 months in the two-week follow-up group compared to the six-week group (P=0.002). There was no difference in caries recurrence requiring treatment between the two follow-up timing groups (P=0.86).

* Conclusion: * Changing the dental rehabilitation under general anesthesia follow-up from six weeks to two weeks improved compliance through six months and decreased the overall number of patients lost to follow-up.

In this article, we proposed an extended generalized Gompertz (EGGo) family of EGGo. Certain statistical properties of EGGo family including distribution shapes, hazard function, skewness, limit behavior, moments and order statistics are discussed. The flexibility of this family is assessed by its application to real data sets and comparison with other competing distributions. The maximum likelihood equations for estimating the parameters based on real data are given. The performances of the estimators such as maximum likelihood estimators, least squares estimators, weighted least squares estimators, Cramer-von-Mises estimators, Anderson-Darling estimators and right tailed Anderson-Darling estimators are discussed. The likelihood ratio test is derived to illustrate that the EGGo distribution is better than other nested models in fitting data set or not. We use *R* software for simulation in order to perform applications and test the validity of this model.

Participants of the tutorial will actively engage with concrete example cases of common, not so common, tricky, interesting and puzzling ethical dilemmas. Some in-depth ethical thinking and theory, as well as very practical and creative solutions, will be explored. Participants will also have the chance to bring their own questions or ethical dilemmas to the workshop (it will be possible to ‘submit’ cases in advance to be discussed in an ethics ‘clinic’) for discussion and help to find solutions.
