The effect of low-level laser therapy as an adjunct to non-surgical periodontal treatment on gingival crevicular fluid levels of transforming growth factor-beta 1, tissue plasminogen activator and plasminogen activator inhibitor 1 in smoking and non-smoking chronic periodontitis patients: A split-mouth, randomized control study


Abstract

Background and Objective

This study aimed to investigate the effects of low-level laser therapy (LLLT) as an adjunct to scaling and root planing (SRP) on smoking and non-smoking patients with chronic periodontitis.

Material and Methods

The study was conducted using a split-mouth design with 30 patients with chronic periodontitis (15 smokers, 15 non-smokers) and 30 healthy individuals matched for age, sex and smoking status as controls. Groups were constituted as follows: Cp+SRP+Sham: non-smokers with chronic periodontitis treated with SRP; Cp+SRP+LLLT: non-smokers with chronic periodontitis treated with SRP+LLLT; SCp+SRP+Sham: smokers with chronic periodontitis treated with SRP; SCp+SRP+LLLT: smokers with chronic periodontitis treated with SRP+LLLT; C: control group comprised of periodontally healthy non-smokers; SC: control group comprised of periodontally healthy smokers. LLLT was first applied on the same day as SRP and again on days 2 and 7 after SRP treatment. Clinical parameters were recorded before non-surgical periodontal treatment (baseline) and on day 30. Gingival crevicular fluid samples were collected before periodontal treatment (baseline) and during follow-up visits on days 7, 14 and 30. Gingival crevicular fluid transforming growth factor (TGF)-β1, tissue plasminogen activator (tPA) and plasminogen activator inhibitor 1 (PAI-1) levels were measured using enzyme-linked immunosorbent assay.

Results

All clinical parameters showed significant reductions between baseline and day 30 following SRP treatment in both the LLLT and sham groups (P<.001). No significant differences were observed between the LLLT and sham groups of either the smokers or non-smokers (P>.05). Gingival crevicular fluid PAI-1 levels decreased significantly in the SCp+SRP+sham and SCp+SRP+LLLT groups (P<.05), and gingival crevicular fluid tPA levels decreased significantly in the Cp+SRP+sham, Cp+SRP+LLLT and SCp+SRP+LLLT groups (P<.05). Gingival crevicular fluid TGF-β1 levels decreased significantly in all treatment groups (P<.05). Although no significant differences were found between the gingival crevicular fluid PAI-1, tPA and TGF-β1 levels of the LLLT versus sham groups (P>.05) at any of the time points measured, both LLLT groups showed significant reductions in tPA/PAI-1 ratios over time.

Conclusion

Within the limits of this study, LLLT may be understood to play a role in the modulation of periodontal tissue tPA and PAI-1 gingival crevicular fluid levels, particularly in smoking patients with chronic periodontitis, and may thus be recommended as an adjunct to non-surgical periodontal treatment.

Probiotics and oral health: A systematic review.

Med Oral Patol Oral Cir Bucal. 2017 Apr 8:0. [Epub ahead of print]

Abstract

BACKGROUND:

Probiotics are microorganisms, mainly bacteria, which benefit the host's health. Many studies support the role of probiotics as a contributor to gastrointestinal health, and nowadays many authors are trying to prove its influence in oral health maintenance.

OBJECTIVES:

To review the published literature with the purpose of knowing the importance of using probiotics as a preventive and therapeutic method for oral infectious diseases management.

MATERIAL AND METHODS:

An electronic search in PubMed database with the keywords "oral health AND probiotics AND dentistry" was conducted. The inclusion criteria were: randomized clinical trials (RCTs) that assess the action of any probiotic strain in the treatment and / or prevention of an infectious oral disease, RCTs that assess the action of any probiotic strain on counting colony forming units (CFU) of oral pathogens, systematic reviews and meta-analysis. The Jadad scale was used to assess the high quality of RCTs.

RESULTS:

Fifteen articles were considered for this review. Of which, 12 were RCTs of good / high quality (Jadad scale), two meta-analysis and one systematic review.

CONCLUSIONS:

The literature reviewed suggests probiotics usage could be beneficial for the maintenance of oral health, due to its ability to decrease the colony forming units (CFU) counts of the oral pathogens. However, randomized clinical trials with long-term follow-up periods are needed to confirm their efficacy in reducing the prevalence/incidence of oral infectious diseases. Furthermore, the recognition of specific strains with probiotic activity for each infectious oral disease is required, in order to determine exact dose, treatment time and ideal vehicles.

In-Office Application of Fluoride Gel or Varnish: Cost-Effectiveness and Expected Value of Perfect Information Analysis

Caries Res 2017;51:231-239


April 08, 2017 
 

Abstract

Application of fluoride gel/varnish (FG/FV) reduces caries increments but generates costs. Avoiding restorative treatments by preventing caries might compensate for these costs. We assessed the cost-effectiveness of dentists applying FG/FV in office and the expected value of perfect information (EVPI). EVPI analyses estimate the economic value of having perfect knowledge, assisting research resource allocation. A mixed public-private-payer perspective in Germany was adopted. A population of 12-year-olds was followed over their lifetime, with caries increments modelled using wide intervals to reflect the uncertainty of caries risk. Biannual application of FV/FG until age 18 years was compared to no fluoride application. Effectiveness parameters and their uncertainty were derived from systematic reviews. The health outcome was caries increment (decayed, missing, or filled teeth; DMFT). Cost calculations were based on fee catalogs or microcosting, including costs for individual-prophylactic fluoridation and, for FG, an individualized tray, plus material costs. Microsimulations, sensitivity, and EVPI analyses were performed. On average and applied to a largely low-risk population, no application of fluoride was least costly but also least effective (EUR 230; 11 DMFT). FV was more costly and effective (EUR 357; 7 DMFT). FG was less effective than FV and also more costly when using individualized trays. FV was the best choice for payers willing to invest EUR 39 or more per avoided DMFT. This cost-effectiveness will differ in different settings/countries or if FG/FV is applied by other care professionals. The EVPI was mainly driven by the individual's caries risk, as FV/FG were significantly more cost-effective in high-risk populations than in low-risk ones. Future studies should focus on caries risk prediction.

Effect of different composite core materials on fracture resistance of endodontically treated teeth restored with FRC posts

Journal of Applied Oral Science
Print version ISSN 1678-7757On-line version ISSN 1678-7765
J. Appl. Oral Sci. vol.25 no.2 Bauru Mar./Apr. 2017
http://dx.doi.org/10.1590/1678-77572016-0306 

Objective
This study evaluated the fracture resistance of endodontically treated teeth restored with fiber reinforced composite posts, using three resin composite core build-up materials, (Clearfil Photo Core (CPC), MultiCore Flow (MCF), and LuxaCore Z-Dual (LCZ)), and a nanohybrid composite, (Tetric N-Ceram (TNC)).

Material and Methods
Forty endodontically treated lower first premolars were restored with quartz fiber posts (D.T. Light-Post) cemented with resin cement (Panavia F2.0). Samples were randomly divided into four groups (n=10). Each group was built-up with one of the four core materials following its manufacturers’ instructions. The teeth were embedded in acrylic resin blocks. Nickel-Chromium crowns were fixed on the specimens with resin cement. The fracture resistance was determined using a universal testing machine with a crosshead speed of 1 mm/min at 1350 to the tooth axis until failure occurred. All core materials used in the study were subjected to test for the flexural modulus according to ISO 4049:2009.

Results
One-way ANOVA and Bonferroni multiple comparisons test indicated that the fracture resistance was higher in the groups with CPC and MCF, which presented no statistically significant difference (p>0.05), but was significantly higher than in those with LCZ and TNC (p<0 .05="" aligned="" flexural="" fracture="" from="" highest="" in="" loads.="" materials="" modulus="" of="" p="" ranking="" same="" tendency="" terms="" the="" values="" was="" with="">
Conclusion

Among the cores used in this study, the composite core with high filler content tended to enhance fracture thresholds of teeth restored with fiber posts more than others.

External and internal resin infiltration of natural proximal subsurface caries lesions: A valuable enhancement of the internal tunnel restoration

Quintessence Int 48 (2017), No. 5  (18.04.2017)

Page 357-368, doi:10.3290/j.qi.a37799, PubMed:28294198



Objective: The aim of this ex-vivo study was to evaluate both the external and the internal penetration ability of a resin infiltrant into natural proximal and macroscopically intact white spot lesions, and to merge this approach with the internal tunnel preparation concept.

Method and Materials: 20 premolars and 20 molars with proximal subsurface lesions (ICDAS, code 2) and respective radiographic lesion depths extending into the middle third of dentin (D2 lesions) were selected and divided into two groups. Treatment needs were confirmed using digital imaging fiber-optic transillumination and laser fluorescence. Deproteinization (NaOCl; 2%) followed, and lesions of Group 1 (control; n = 20) were etched (HCl; 15%) and externally infiltrated (Icon). Accordingly, the specimens of Group 2 (n = 20) were treated with the resin infiltrant from external; then, internal Class I tunnels were prepared, lesions were internally infiltrated (Icon), and the occlusal cavities were restored (G-ænial Flo X) after etching (H3PO4 gel; 40%). Teeth were cut perpendicular to the proximal lesion surfaces, and percentage infiltrations were analyzed using confocal laser microscopy and a dedicated image manipulation program (GIMP).

Results: Regarding the external infiltration, no differences between both groups were detected (P = .114; Mann-Whitney). Additional internal application of the resin infiltrant significantly increased the percentage amount of enamel lesion infiltration (P < .0001; Wilcoxon).

Conclusion: External and internal infiltration seem to complement the internal tunnel approach, thus remediating the drawbacks of the latter by occluding and stabilizing the porous areas of the proximal caries lesion, and preserving both the marginal ridge and the proximal contact area.

Dentsply Sirona Orthodontics announces the expansion of treatment indications for the MTM® (Minor Tooth Movement) Clear•Aligner. The clear aligner combines proven orthodontic techniques with advanced digital modeling to provide dental professionals with a streamlined solution for treating minor anterior misalignments.
MTM® Clear•Aligner is uniquely engineered to deliver the space and
force needed to accomplish tooth movement. The technology utilizes a proprietary “open pathway” architecture that allows teeth to move easily into the desired positions. Unlike other clear aligners, MTM® Clear•Aligner does not require clinicians to bond unsightly attachments to teeth, to accomplish movement. No attachments saves practice chair time and provides for a more esthetically pleasing treatment solution for the patient. To facilitate tooth movement MTM® Clear•Aligner uses integrated “force points”, programmed into the aligner, to provide a greater range of tooth movements, while making aligner placement and removal easy for the patient. 

MTM® Clear•Aligner targets the movement and positioning of the six most visible teeth, on both the upper and lower arches. These teeth are known as the social six. The aligner movements address tooth; spacing, tipping, torqueing, intrusion, extrusion, and rotation. Ideal candidates are those who are experiencing adult tooth crowding, orthodontic relapse, or those who seek cosmetic enhancements. Of the thousands of cases completed since the products’ launch, many dental professional note that most of their patients sought simply to improve their smile.
Brad Clatt, Group Vice President of Orthodontics states, “Whether a dental professional currently prescribes clear aligners, or has been waiting for an aligner system that better fits the needs of their patients, MTM Clear•Aligner is a simple solution to address one of the most common misalignments seen in adult patients today. Dentsply Sirona prides itself on keeping patient care, where it belongs, in the hands of the clinician, and offers each clinician a customized approach to treating their patients. MTM Clear•Aligner is a highly affordable solution for both doctor and patient, with the ability to move the social six to the desired position, creating the patient’s Ideal Smile.” 

To help offices get started with MTM Clear•Aligner, Dentsply Sirona Orthodontics offers an attractively-priced Welcome Kit that includes discounted patient cases, a web based training course, practice marketing and office integration resources. To learn more about the MTM Clear•Aligner visit the Dentsply Sirona booth #2414, during the American Association of Orthodontists (AAO), Annual Session.

NuSmile NeoMTA® Launches in Canada



Breakthrough material is the only affordable MTA specifically optimized for pediatric dentistry
HOUSTON, TEXAS, April 6, 2017—NuSmile Ltd., the worldwide leader in pediatric esthetic restorative dentistry, announced today that its NuSmile NeoMTA is now available in Canada.
NuSmile NeoMTA is the first and only affordable MTA specifically optimized for pediatric dentistry. The ideal treatment for pulpotomies, direct and indirect pulp capping, and apexification, it is quickly wash- out resistant, non-staining and has excellent handling properties. NuSmile NeoMTA is also bioactive and non-toxic, delivering peace of mind that formocresol may not provide.
Cost-effective for pediatric dentistry
Historically, many dentists who would have preferred to use bioactive, non-toxic MTA rather than formocresol for pediatric pulp therapy found MTA to be cost-prohibitive. This is no longer an issue, as NuSmile NeoMTA’s cost per gram is dramatically less than that of all other leading MTAs. Moreover, its unique dessicant-lined bulk packaging system allows dentists to use only what is needed for each pulp therapy, virtually eliminating waste.
Truly bioactive
Unlike formocresol and resin/MTA blends, NuSmile NeoMTA is bioactive, hydrophilic, non-toxic and 100 percent biocompatible. MTA has been widely studied and is proven to trigger the formation of hydroxyapatite leading to dentinal bridging. NuSmile NeoMTA contains no resins, and thus delivers unmatched performance for pediatric dental procedures.
Unsurpassed handling
NuSmile NeoMTA’s combination of ultrafine powder and proprietary gel delivers exceptional mixing, handling and placement. The powder and gel can be mixed to form a putty-like consistency that is very easy to work with and stays in place.
Superior to other MTAs
NuSmile NeoMTA is superior to other MTAs in ways that transcend cost. It is quickly washout resistant and sets much faster than other MTAs. It is also more radiopaque than many MTAs, readily visible in radiographs. NuSmile NeoMTA’s non-staining formula is especially useful for pulp therapy treatment prior to restoration with either zirconia crowns or composites.
NuSmile NeoMTA received the coveted “Best Product” designation based on an extensive evaluation conducted by Dental Product Shopper magazine. It was also named one of the “Top 100 Products” in the entire dental industry by Dentistry Today magazine.

SUNSTAR to Sponsor 2017 UNC Perio Expo



Company celebrates 20th anniversary of its first sponsorship of the event
SCHAUMBURG, ILLINOIS, April 4, 2017— Sunstar Americas today announced that it will sponsor the UNC Perio Expo May 4-6, 2017 at the University of North Carolina School of Dentistry in Chapel Hill, North Carolina.
Sunstar has a long and proud history of supporting groundbreaking research and educational programs. In fact, the company also sponsored the 1997 UNC Perio Expo, which is widely credited with playing a crucial role in identifying the needs and opportunities for the control of periodontal disease. That event built upon an event the company had sponsored 11 years earlier, the Sunstar Portside Symposium in Kobe, Japan, which was the first global event to demonstrate the connection between oral health, general body health and overall well- being. Other Sunstar educational initiatives include the Joslin-Sunstar Diabetes Education program. This program, begun in 2008, educates dentists as well as physicians about the link between diabetes and gum disease as well as other oral health issues. Such initiatives are a clear reflection of Sunstar’s motto: “Always strive to help people everywhere achieve better health and enhance their quality-of-life.”
The UNC Perio Expo is a blended showcase that brings internationally recognized speakers to a two-day program covering important concepts in periodontics and implantology, including disease diagnosis, treatment and management. The two-day agenda is divided into six sessions:
  1. Periodontology and Global Health: A 10 Year Look Ahead

Effect of acidity of in-office bleaching gels on tooth sensitivity and whitening: a two-center double-blind randomized clinical trial




Clinical Oral Investigations

pp 1–8

Abstract

Objectives

The study aimed to compare the tooth sensitivity (TS) and bleaching efficacy of two hydrogen peroxide gels with different pHs (acid pH [Pola Office, SDI] and the neutral pH [Pola Office+, SDI]) used for in-office bleaching.

Materials and methods

Fifty-four patients from Brazil and Chile, with right superior incisor darker than A2, were selected for this double-blind, split-mouth randomized trial. Teeth were bleached in two sessions, with 1-week interval. Each session had three applications of 8 min each, according to the manufacturer’s instructions. The color changes were evaluated by subjective (Vita Classical and Vita Bleachedguide) and objective (Easy shade spectrophotometer) methods. Participants recorded TS with 0–10 visual analog scale. Color change in shade guide units (SGU) and ΔE was analyzed by Student’s t test (α = 0.05). The absolute risk and intensity of TS were evaluated by McNemar’s test and Wilcoxon-paired test, respectively (α = 0.05).

Results

All groups achieved the same level of whitening after 30 days of clinical evaluation. The use of a neutral in-office bleaching gel significantly decreases the absolute risk of TS (28%, 95% CI 18–41) and intensity of TS when compared to the acid bleaching gel (absolute risk of 50%, 95% CI 37–63).

Conclusion

The use of a neutral in-office bleaching agent gel produced the same whitening degree than an acid bleaching gel but with reduced risk and intensity of tooth sensitivity.

Clinical significance

Clinicians should opt to use in-office bleaching with a neutral gel than an acid product because the former causes a significant lower risk and intensity of tooth sensitivity.

Guided Immediate Implant Placement with Wound Closure by Computer-Aided Design/Computer-Assisted Manufacture Sealing Socket Abutment: Case Report.

Int J Oral Maxillofac Implants. 2017 Mar/Apr;32(2):e63-e67. doi: 10.11607/jomi.4770.

Abstract

Digital technology has been widely used in the field of implant dentistry. From a surgical standpoint, computer-guided surgery can be utilized to enhance primary implant stability and to improve the precision of implant placement. From a prosthetic standpoint, computer-aided design/computer-assisted manufacture (CAD/CAM) technology has brought about various restorative options, including the fabrication of customized abutments through a virtual design based on computer-guided surgical planning. This case report describes a novel technique combining the use of a three-dimensional (3D) printed surgical template for the immediate placement of an implant, with CAD/CAM technology to optimize hard and soft tissue healing after bone grafting with the use of a socket sealing abutment.

Comparison of two cone-beam computed tomography systems in the visualization of endodontic structures

Swiss Dent J. 2017;127(3):221-229.

Abstract

An important part of endodontic diagnosis and treatment is the adequate visualization of root canal anatomy. The objective of the present study was to compare two different three-dimensional cone-beam computed tomography (CBCT) systems, Scanora 3D and 3D Accuitomo 170, with respect to their visualization of endodontic canal systems and potential pathological alterations. Seventy extracted human teeth were investigated with regard to the radiographic detection of number of root canals, lateral canals, root canal fillings and posts, vertical root fractures, and the occurrence of image artifacts. For each evaluation parameter under investigation the radiographic diagnoses obtained by the two different CBCT systems under investigation were similarly accurate, without statistically significant differences. The evaluation of teeth containing high-density foreign materials was impaired for both CBCT systems because of image artifacts. However, a difference between the CBCT systems was not observed. In conclusion, both CBCT systems were found to be similarly suitable for the visualization of endodontic structures in vitro.

University of California, Irvine Study Shows OraCoat® XyliMelts® discs reduce plaque by over 50%

-->


Study Demonstrated that OraCoat XyliMelts Effectively Improve Many Symptoms of Dry Mouth Including the Ability to Eat and Swallow

Bellevue, WA (March 22, 2017) – Researchers at the University of California, Irvine analyzed the effects of OraCoat® XyliMelts® oral adhering discs on people affected by clinically diagnosed dry mouth. The double-blind, randomized study demonstrated that XyliMelts reduce tooth plaque by 58% and improve the ability to eat and swallow in those affected by dry mouth.

Dry mouth is the subjective sensation of oral dryness that affects up to 60% of the elderly population, and is caused by various disorders and oral cancer treatments such as radiation to the head and neck. Additionally, a number of medications, including over-the-counter drugs such as antidepressants, decongestants, antihistamines, appetite suppressors, and diuretics produce symptoms of dry mouth. Dry mouth symptoms include a sticky, dry sensation in the mouth, tongue roughness, frequent liquid consumption, difficulty speaking and swallowing, and sleep disruption.

OraCoat XyliMelts is a patented dry mouth product that sticks to the gums on the outside of a molar, releasing one-half gram of Xylitol, which stimulates saliva, and cellulose gum which, combined with saliva, forms a lubricating gel. Xylitol, slowly released in the mouth so it lingers, is effective for reducing dry mouth and tooth decay. Moreover, XyliMelts used at night while sleeping when saliva flow is lowest is the most effective delivery of Xylitol.*

The 21-day clinical study evaluated in patients with dry mouth the effects of XyliMelts on saliva production and ability to neutralize acids, as well as patient comfort. The study was administered to five test subjects who used XyliMelts as recommended: two discs while sleeping, one on each side of the mouth, and as needed during the day. On average, the subjects used four discs each day during daytime hours.

Test results showed the clinical usefulness of XyliMelts for effectively relieving dry mouth. Researchers found that XyliMelts significantly reduced sleep disruption by lasting for six hours while sleeping, when dry mouth is at its worst, while improving mouth wetness upon waking in the morning. XyliMelts also diminished tooth sensitivity to hot, cold, and spicy foods and drinks. The adhering discs more than doubled saliva production while in place, and increased the ability of saliva to neutralize acids that cause tooth decay. Most importantly, the test displayed that subjects using XyliMelts in conjunction with standard oral care showed heightened saliva flow compared to standard oral care alone. XyliMelts not only alleviates symptoms of dry mouth, they also stimulate saliva production.

Overall, subject feedback to XyliMelts was positive, with subjects stating that they would continue using the discs while recommending them to others. Subjects also reported XyliMelts as easy to use with a favorable taste and overall mouth feel.

The study was published on February 13, 2017, and can be found here.

In a March 2016 Clinicians Report® survey of dentists published by CR Foundation, an independent, non-profit, dental education and product testing foundation, 152 dentists who were familiar with OraCoat XyliMelts rated it more effective than any other remedy for dry mouth, including prescription drugs which came in second.

XyliMelts are available over the counter at CVS and Rite Aid. For more information on XyliMelts, visit www.oracoat.com. Consumers interested in receiving a free sample (limit one per household) should call 1-855-275-4766.

A companion product to OraCoat XyliMelts for oral cancer patients is OraCoat XyliGel®, a soothing gel with 17% Xylitol buffered to pH 7.4 to relieve dry mouth. It works especially well for people with very low levels of saliva. XyliGel is available online at oracoat.com.

Dentsply Sirona Prosthetics Introduces the First High Impact Pourable Acrylic Denture Base




York, Pennsylvania, April 4, 2017 – Dentsply Sirona, The Dental Solutions Company, announced the introduction of Lucitone® HIPA (High Impact Pour Acrylic).

Lucitone® HIPA is a high impact pourable acrylic denture base. It is the first pourable acrylic denture base on the market to exceed both of the required ISO standards for improved impact resistance. Lucitone HIPA was introduced in the United States in January and launched globally at the IDS Meeting in Cologne.
Catherine Bonser, Dentsply Sirona Director of Prosthetics Global Removable Products, commented “Lucitone HIPA truly provides solutions to dental labs. Labs who use the traditional heat cured technique can now work faster, while still providing a high impact denture. Increased durability reduces the potential for fractures in the dental lab resulting in time and cost savings due to less remakes. And, increased durability reduces the risk of breakage from the patient during normal use.” 
Lucitone HIPA is a self-curing denture base material designed for use in fabrication, repair, rebasing, or relining of full and partial dentures, including implant overdentures or other dental appliances. In addition to being the first high impact pourable acrylic denture base, Lucitone HIPA also features excellent color stability and accurate fit to model.

Abstract


Aim

To evaluate the outcome of secondary root canal treatment (retreatment) on posterior teeth in relation to the residual volume of coronal tooth structure, measured with an intraoral scanner, using periapical radiography and cone beam computed tomography (CBCT).

Methodology

A total of 137 posterior teeth in 121 patients were assessed clinically and radiographically using periapical radiographs and CBCT scans at baseline and 1-year after root canal retreatment. The increase or decrease in the size of preoperative periapical radiolucencies and development of new radiolucencies were assessed by a consensus panel consisting of two pre-calibrated examiners. A clinical impression was obtained for each tooth after completion of root canal retreatment, before the placement of the temporary restoration and following cast restoration placement to produce two casts. All casts were scanned using an intraoral digital scanner and the three-dimensional volume of remaining tooth structure calculated. Teeth were also classified according to the number of remaining coronal walls before core build-up. Chi-square test was used to determine the association between the outcome of root canal retreatments and the volume of remaining coronal tooth structure.

Results

At the 1-year recall, teeth retaining less than 30% of their original tooth structure volume had a significantly higher proportion of unfavourable outcomes (χ2, P<0 .05="" 1.026-6.487="" 2.580="" 95="" ci="" odds="" p="" ratio="">

Conclusions

The loss of tooth structure volume is an objective parameter that can be used to predict the probability of success of root canal retreatments. At 1-year follow-up, the percentage of unfavourable outcomes of root canal retreated teeth was significantly higher when less than 30% of the original tooth tissue structure was present at baseline.
