1. Tooth survival of endodontically treated molars
A total of 220 endodontically treated permanent molar teeth in 203 subjects on a waiting list for fixed prosthodontic treatment at the Faculty of Dentistry-Mahidol University, Thailand.
Three levels of remaining tooth structure:
Type I remaining tooth structure denoted maximum remaining tooth structure. The amount of remaining coronal tooth structure was approximately that of a Class I cavity preparation with at least 2 mm of surrounding wall thickness.
Type II denoted moderate remaining tooth structure. The amount of remaining coronal tooth structure was approximately a Class II cavity preparation with no less than 2 walls with at least 2 mm thickness.
Type III denoted minimum remaining tooth structure as the remaining coronal tooth structure had less than 2 walls with at least 2 mm thickness, ..

9. Endodontics vs implantat
Apples and oranges
Comparing case-selected, low-risk implants with heroic salvation efforts by endodontics is biased
Comparing case-selected, low-risk endodontics with high-risk, money- or patient-driven implants is biased
True comparisons difficult, may be impossible
The accumulation and presentation of individual cases give information of the individual possibilities of each method: endodontists need to knbow what implantologists can do, and vice versa

11. Comparison of success of implants versus endodontically treated teeth.
A chart review was carried out in 2 group specialty practices in the same city. Implant data were collected from a periodontic practice and endodontic data from patients presenting for routine recall or treatment of another tooth at an endodontic practice. Charts were selected in alphabetical sequence, with no exclusions made for systemic disorders, time of implant loading, or tooth implant position in the mouth, and were reviewed on patients with clinical and radiographic follow-ups more than 1 year after treatment.

12. Endodontics vs implant
Success was defined as radiographic evidence that the implant or treated tooth was still present in the mouth, and that there was no notation of signs or symptoms requiring intervention during the follow-up period in the chart notes.

13. Endodontics vs implant
Uncertain findings were defined for implants as charted mobility greater than class I, radiographically detectable bone loss, or additional surgical procedure required. Uncertain findings for endodontic treatments were defined as charted mobility greater than class I, radiograph judged as periapical index score of 3 or greater (Table 2), or orthograde endodontic procedure or apical surgery required (22).

14. Endodontics vs implant
Typical surgical interventions for implants were flap exposures for debridement, with or without grafting osseous material. Uncertain findings for endodontic treatments were defined as charted mobility greater than class I, radiograph judged as periapical index score of 3 or greater (Table 2), or orthograde endodontic procedure or apical surgery required (22). Preoperative values were not considered.

16. Optimizing Prognosis
Case selection: If in doubt, do not wait: prevention is easier than cure
Asepsis for vital pulps; antisepsis for infected pulps
Bacteria-free canals: adopting procedures known to provide a high probability of no growth
Conventional fillings of high quality
Coronal filling and molar coverage
Judicious inclusion in prosthetic restorations
