"By means of a double-chamber model, different root canal filling materials and procedures were compared. Briefly, the root canals of single-rooted human teeth, extracted for periodontal reasons, were instrumented and obturated by gutta-percha/Pulp Canal Sealer EWT (PCS) or by Resilon, in association with different sealers (Real Seal, RelyX Unicem or Meta). Obturation was achieved by traditional continuous wave of condensation technique (TCWCT), a modified version of it (MCWCT), or single cone technique (SCT). The obturated roots, inserted in a double-chamber model, were sterilized by gamma irradiation. Next, Enterococcus faecalis was added to the upper chamber and the specimens were incubated at 37°C for up to 120 days: the development of turbidity in the lower chambers' broths indicated bacterial leakage through the obturated root canals. The kinetics of leakage were analyzed in different groups by means of Kaplan-Meier statistics and compared by log-rank test. The results showed that root canals obturated with either gutta-percha/PCS using the MCWCT, Resilon/Real Seal SCT or Resilon/RelyX Unicem using the TCWCT displayed significantly better performance than the remaining groups (p < 0.01). Histological evaluation, performed to investigate microbial localization inside specimens, confirmed that this parameter varied according to the obturation procedures and materials employed. This ex vivo study indicates that gutta-percha/PCS, if used with the MCWCT, is as effective as Resilon when coupled to Real Seal with the SCT or, interestingly, to RelyX Unicem with the TCWCT. These data suggest that further improvement of the currently employed root canal filling procedures is achievable, depending on booth the filling materials and the technique employed, thus encouraging clinical studies in this direction."

"Latar Belakang: Kebocoran mikro dipengaruhi oleh jenis semen saluran akar. Tujuan: menganalisis tingkat kebocoran mikro pengisian saluran akar menggunakan semen resin epoksi (SRE) dan Mineral Trioxide Aggregate (SMTA). Metode: Tiga puluh dua gigi premolar bawah, dibagi dua kelompok sama besar, yaitu kelompok SRE dan SMTA. Setelah pengisian saluran akar, sampel diinkubasi (370C, 24 jam), kemudian direndam dalam tinta India selama 7 X 24 jam. Sampel didekalsifikasi sampai dengan transparan. Kedalaman penetrasi tinta dievaluasi dengan mikroskop stereo. Skor 1 untuk penetrasi tinta 0-0,5 mm, skor 2 untuk penetrasi tinta 0,51-1 mm, dan skor 3 untuk penetrasi tinta >1 mm. Hasil: Distribusi proporsi kebocoran terbesar kelompok SRE terdapat pada skor 1, yaitu sebesar 37,5%. Sedangkan distribusi proporsi kebocoran terbesar kelompok SMTA terdapat pada skor 1, yaitu sebesar 21,9%. Tidak terdapat perbedaan bermakna antara kelompok SRE dan SMTA. Kesimpulan: Semen resin epoksi dan semen MTA memiliki tingkat kebocoran yang sama.

Background: The microleakage affected by type of root canal sealer.

Purpose: to analyze the microleakage of obturation using epoxy resin-based (SRE) and mineral trioxide aggregate-based (SMTA) as root canal sealer.

Methods: Thirty two mandibular first premolars were equally divided into two groups. They were SRE group and SMTA group. After obturation, the specimens were incubated (370C, 24 h), immersed in Indian ink for 7 days, decalcified, dehydrated, and made transparent. Dye penetration were evaluated under stereomicroscope and given score 1-3. Specimen with 0-0,5 mm dye penetration was given score 1, while 0,51-1 mm penetration was given score 2, and > 1 mm was given score 3. The results were statistically analyzed with Kolmogorov Smirnov test.

Results: The largest proportion distribution in SMTA group was score 1 (37,5%), whilst the largest proportion distribution in SMTA group was score 1 (21,9%). There was no significant difference between the microleakage of epoxy resin-based and mineral trioxide aggregate-based sealer, observed from the one-third apical leakage.

Conclusion: The microleakage of mineral trioxide aggregate based sealer and epoxy resin-based sealer was relatively similar."

"Endodontic glide path is the creation of a smooth patency from canal orifice to apex, which can be performed manually or with small tapered NiTi rotary instruments. The use of stainless steel (SS) hand K-files inserted in a reciprocating handpiece can be a possible alternative to create a mechanical glide path. The aim of this study was to compare the cyclic fatigue resistance between SS K-files used in a reciprocating motion and NiTi rotary instruments in artificial curved canals. Ten SS size 15 K-files used with the M4 handpiece (SybronEndo, Glendora, CA, USA) and ten PathFiles (Maillefer-Dentsply, Ballaigues, CH, Switzerland) NiTi rotary instruments size 16, 0.02 taper were tested for resistance to cyclic fatigue. The time to fracture inside an artificial curved canal was recorded for each instrument. Data were analyzed by one-way ANOVA and Tukey HSD test. Mean time (and SD) to failure was 464 s (±40.4) for the Group PF (NiTi rotary PathFile), and 1049 s (±24.8) for the Group M4 (SS K-files reciprocating) with a statistically significant difference between the two groups (p = 0.033). The SS 15 K-files used with the M4 handpiece showed a significant greater resistance to cyclic fatigue when compared to the NiTi rotary PathFiles. Therefore, the use of small size SS files in a reciprocating motion might be a rational choice for the creation of a mechanical endodontic glide path in curved root canals."

"The correlation between endodontic-periodontal lesion has been documented well by researches. Endodontic lesion originates from pulp, while periodontal lesion originates from periodontal tissues. Anatomically they are connected by apical foramen, lateral canal and accesories, as well as dentin tubules. The correlation appeared as the endodontic defect can be from periodontal lesion, or a periodontal defect is from a pulp tissue. Together they can emerge and form a combination lesion. Endodontic infections have been highly correlated with deeper periodontal pockets and furcation involvement in mandibular, the causal relationship between the two pathoses has not yet been established. This consensus supports the influence of degenerated or inflamed pulp that can happen on the periodintium; but not all researchers agree about the effect of periodontal disease on the pulp. Conclusion: The mechanism of endo-perio lesion need to taken care in order to have appropriate diagnostic so that the right therapy would be able to keep the teeth in the oral cavity."

The prevalence of vertical distortion in the periapical radiograph of the anterior maxillary teeth is quite significant and cingulum is commonly used as the reference of vertical distortion in anterior radiograph.

Objective: To evaluate the limit of vertical angulation error that still can be tolerated.

Methods: Periapical radiograph with vertical angle 0° was obtained from 30 maxillary incisors as reference, then the vertical angulation was changed into -10°, +10°, -15°, +15°, -20° and +20°. Long axis of the teeth was adjusted parallel to the film. Tooth length and cingulum width with vertical angulation alteration was measured and compared to the actual length. All of the measurement was tested using T test.

Results: There were no significant differences between all the measurements of tooth length with the alteration in vertical angulation (p>0.05), whereas cingulum width had a significant difference at +15° and -10°, p<0.05.

Conclusion: Tooth length in periapical radiograph of maxillary incisor with parallel position is still tolerable until 20º vertical angle errors. Cingulum width on radiograph with +15º vertical angle alteration is significantly narrowed and on radiograph with -10° vertical angle alteration is significantly widened."
