The Dilemma of the Open Gingival Embrasure Between Maxillary Central Incisors

Aim: The aim of this report is to present the etiology, diagnosis, and treatment planning strategy in the presence of an open gingival embrasure between the maxillary central incisors. Background: The open gingival embrasure or “black triangle” is a visible triangular space in the cervical region of the maxillary incisors. It appears when the gingival papilla does not completely fill in the interdental space. The space may occur due to: (1) disease or surgery with periodontal attachment loss resulting in gingival recession; (2) severely malaligned maxillary incisors; (3) divergent roots; or (4) triangular-shaped crowns associated with or without periodontal problems and alveolar bone resorptions. Report: The post-treatment prevalence in adult orthodontic patients is estimated to be around 40% compromising the esthetic result. Conclusion: Several methods of managing patients with open gingival embrasure exist, but the interdisciplinary aspects of treatment must be emphasized to achieve the best possible result. The orthodontist can play a significant role in helping to manage these cases

Perception of the Most Esthetically Pleasing Incisal Embrasure Design

OBJECTIVES: To determine the frequency of female dentate patients' most appealing incisal edge embrasure designs. METHODOLOGY: The sample consisted of 385 female dentate patients between 18 to 40 years of age visiting Sardar Begum Dental College and Hospital, Peshawar, from January 2021 to June 2021. The subject's perception was recorded by having the subjects visualize a set of five photographs showing different categories of incisal edge embrasure designs classified by Foulger and Tredwin. The labels of these different photograph categories were obscured using a non-transparent tape, and A, B, C, D, and E; names were assigned to them, respectively, to avoid bias. Means and standard deviations were calculated for quantitative variables like age, while the frequency was calculated in percentage for categorical variables for the most appealing incisal edge embrasure design. RESULTS: The most attractive incisal edge embrasure design amongst the female dentate patients was the "Ideal" design with 33.8%. The second most attractive design displayed "Equal" incisal edge embrasures with 31.4. The "Reversed" and "None" categories had 12.2% and 9.9% percentages. The least attractive design amongst these females was with "Exaggerated" incisal edge embrasures. CONCLUSION: Female dentate patients' most appealing incisal edge embrasure design displays the "Ideal" incisal edge embrasure form

The Relationship Between Orthodontics and Periodontics: An Interdisciplinary Approach

ABSTRACT In the recent years rapid advances in dental techniques and dental materials had taken place. Public interest had developed in maintaining a good oral health with attractive smile, which has resulted in understanding the interrelationships between periodontics and orthodontics. Orthodontics and periodontics are interrelated in variety of situations and a multidisciplinary approach is often necessary. Higher susceptibility of plaque accumulation in patients undergoing orthodontic treatment made involvement of periodontist almost unavoidable, also orthodontic treatment frequently results in undesirable periodontal changes which require immediate attention. Making the most of what these two specialities offer each other begins with the identification of periodontal problems that could become more complicated during orthodontic therapy and conversely those that could benefit from orthodontic therapy. However a standard language between periodontist and orthodontist must always be established to eliminate the existing communication barrier and to improve the outcomes of the whole treatment

The significance of embrasure design on the fracture load of fixed denture prosthesis: an in vitro study

OBJECTIVE: This study evaluated two embrasure designs by measuring their differential effect on load at failure of provisional fixed partial dentures (FPDs) fabricated of five commercially available polymer-based restorative materials. METHODS: Five provisional C&B materials were selected to fabricate FPDs with two different embrasure designs: sharp vs. rounded embrasures (n=12 for each material). The test materials included: Telio CAD (Ivoclar-Vivadent), Coldpac (Motloid), Protemp Plus (3M), VersaTemp (Sultan), and Turbo Temp (Danville). The embrasures were formed using prefabricated cutters with measured Radii (0.002r and 0.03r) and a fixture to hold each provisional FPD in place for the uniform standardized cuts. Molds for the CAD/CAM provisional FPDs were used to fabricate the syringeable temporary materials and form bridges with the same geometric design. All provisional bridges were cemented using Temp-Bond (Kerr) to the corresponding standardized abutments and tested to failure in a universal Instron testing machine by loading each specimen compressively in the mid pontic region. The load at break was recorded in Newton. A one-way analysis of variance (ANOVA) was used to compare the difference in each group’s mean. RESULTS: A significant difference in fracture load was found between the two groups of designs, in which the round embrasure was significantly stronger than was the sharp. A significant difference also was found between the type of temporary material used to fabricate the bridge in the two groups, and except for Coldpac, no significant difference between the embrasure anatomies was found. Fatigue loading did not appear to influence the two bridges’ fracture load, but it did show a significant difference with respect to the modulus of elasticity, in that the bridges that underwent fatigue loading showed a higher elastic modulus by comparison to the control group. Another variable that influenced the modulus of elasticity was the type of temporary material used to fabricate the bridge, in which TelioCAD was found to be the stiffest. However, the embrasure design did not seem to affect the bridges’ rigidity. CONCLUSION: A significant difference was found in fracture strength between the rounded and sharp embrasure design. Except for Coldpac, the rounded embrasure showed higher fracture toughness than did the sharp. No significant correlation was found between the two embrasure designs and the modulus of elasticity. Interestingly, the fatigued bridges that underwent cyclic loading showed a higher modulus of elasticity. The sharp embrasure design showed no fracture in the pontic region, while the rounded design did in 5.47% of the sample. This may be explained by the photoelastic bridges, in which the stress diffuses in the rounded design to include the pontic region, while in the sharp design, the stress is concentrated on the connector area. Stress analysis, both by means of photoelastic and finite element analysis, demonstrated that the bridge with the sharp embrasure design’s stress was high in the connector area compared to the round embrasure design

Factors associated with the appearance of gingival papillae

Chow YC, Eber RM, Tsao Y-P, Shotwell JL, Wang H-L. Factors associated with the appearance of gingival papillae. J Clin Periodontol 2010; 37: 719-727 doi: . The purpose of this study was to evaluate factors associated with the fill of inter-dental spaces by gingival papillae.Ninety-six adult subjects were evaluated. Papilla score (PS), tooth form/shape, interproximal contact length and gingival thickness were recorded for 672 maxillary anterior and first pre-molar interproximal sites. Statistical analyses included a non-parametric χ 2 test, anova , the Mixed Procedure for SAS and Pearson's correlation coefficient ( r ).Papilla deficiency was more frequent in older subjects ( p <0.05), as papilla height decreased 0.012 mm with each year of increasing age ( p <0.05). Competent papillae (complete fill inter-dentally) were associated with: (1) crown width: length ges;0.87; (2) proximal contact length ges;2.8 mm; (3) bone crest-contact point ≤5 mm; and (4) interproximal gingival tissue thickness ges;1.5 mm. Gingival thickness correlated negatively with PS ( r =−0.37 to −0.54) and positively with tissue height ( r =0.23–0.43). Tooth form (i.e. crown width to length ratio) correlated negatively with PS ( r =−0.37 to −0.61). Other parameters failed to show any significant effects.Gingival papilla appearance was associated significantly with subject age, tooth form/shape, proximal contact length, crestal bone height and interproximal gingival thickness.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/79213/1/j.1600-051X.2010.01594.x.pd
