Which numbering system uses two-digit codes for each tooth based on quadrant and position?
Universal Numbering System
Palmer Notation System
FDI World Dental Federation System
Black’s Classification
The FDI system assigns a two-digit code: the first digit for quadrant (1–4 permanent, 5–8 primary) and the second for tooth position (1–8). It is used internationally for clarity in charting. This avoids confusion between right and left. Reference
In the Universal Numbering System, what number is assigned to the maxillary right central incisor?
8
9
7
1
In the Universal system, permanent teeth are numbered 1–32. The maxillary right central incisor is tooth #8. Tooth #9 is its contralateral counterpart. Reference
What symbol is commonly used in dental charting to indicate a missing tooth?
Crossed out X through the tooth
Diagonal slash through the crown
Solid circle around the tooth

A diagonal slash through the tooth drawing indicates it’s missing. This is standard in most charting protocols. It differentiates from extractions still pending. Reference
Which abbreviation represents an amalgam restoration on the occlusal surface?
OA
AMO
O-A
O
In many charting systems, Occlusal Amalgam is abbreviated as O-A. 'O' denotes the occlusal surface and 'A' stands for amalgam. This shorthand is taught in dental assisting programs. Reference
In periodontal charting, what measurement indicates a healthy sulcus depth?
1–3 mm
4–5 mm
6–7 mm
0 mm
Normal periodontal sulcus depth ranges from 1 to 3 mm. Depths beyond 3 mm suggest pocket formation. Consistent measurement is required at six sites per tooth. Reference
What abbreviation is used to indicate a root canal treatment?

Shading facial surface
Outline only on root
Class II involves proximal surfaces of posterior teeth. Charting shows shading on the mesial or distal surface. It distinguishes from Class I which is occlusal only. Reference
What does furcation involvement Grade II signify on a molar?
Horizontal loss >3 mm
Complete communication
Mild bone loss
No furcation detected
Grade II furcation is a cul-de-sac with horizontal bone loss >3 mm but not through-and-through. Grade III is complete communication. Accurate charting guides treatment. Reference
Which symbol denotes a planned crown preparation?
Dashed outline around crown
Solid black shading of crown
Red dot at margin
Blue cross-hatch inside crown
A dashed outline around the tooth crown shows a proposed restoration like a crown. This indicates treatment is planned but not completed. It differs from solid shading of existing work. Reference
In charting, how is a vertical root fracture usually indicated?
Jagged red line along root length
Green circle around apex
Blue shading of crown
Dashed line across crown
A jagged red line along the root denotes a fracture extending vertically. This highlights urgency of management. Other fractures use different markings. Reference
What classification measures tooth mobility when movement exceeds 1 mm horizontally but no vertical displacement?
Class I
Class II
Class III
Class 0
Mobility Class II is movement >1 mm in a horizontal direction only. Class I is <1 mm and Class III includes vertical displacement. Accurate mobility recording affects periodontal prognosis. Reference
How is a 6 mm periodontal pocket marked in a chart?
Red number 6 at site
Blue triangle at site
Green shading around root
Dashed circle around tooth
Deep pockets ?5 mm are recorded in red to indicate severity. The number is placed at each probing site. This helps track periodontal disease progression. Reference
Which abbreviation indicates the palatal surface of a maxillary tooth?
B
P
L
M
On maxillary teeth, the lingual surface is often termed palatal and abbreviated 'P'. On mandibular arches it’s still 'L' for lingual. Accurate surfaces guide diagnosis and treatment. Reference
What does the code 'D1110' represent in dental charting?
Adult prophylaxis
Composite restoration
Extraction
Endodontic therapy
ADA code D1110 stands for adult prophylaxis (cleaning). Charting codes align clinical notes with insurance claims. This standardization ensures accurate billing. Reference
How is an open contact between teeth indicated in charting?
Solid X between teeth
Arrow pointing to gap
Dashed line connecting teeth
Red shading of interproximal
An arrow pointing to the contact area denotes an open contact needing correction. It differentiates from tight contacts. This symbol alerts clinicians during restoration. Reference
Which marking indicates a furcation involvement Grade III in charting protocols?
Filled triangle at furcation
Open triangle at furcation
Red circle around root
Diagonal slash through root
An open triangle at furcation indicates Grade III (through-and-through). A filled triangle is Grade II. Clear symbols help periodontal treatment planning. Reference
What symbol is used to denote ankylosed teeth in advanced charting?
Solid black triangle at apex
Dashed outline of crown
Red X over root
Blue shading of root
A solid black triangle at the apex signals ankylosis. It denotes fusion of tooth to bone with no periodontal ligament. Identification prevents failed orthodontic movement. Reference
In periodontal charting, what does a ‘Miller Class II’ gingival recession indicate?
Recession reaching mucogingival line without interdental loss
Recession beyond mucogingival line with interdental bone loss
Complete root coverage possible
No recession but papilla loss
Miller Class II recession extends to or beyond the mucogingival junction without interdental bone or soft tissue loss. Full root coverage is still achievable. Class III and IV have interdental loss. Reference
Which notation designates a sinus lift procedure in charting?

A star symbol marks supernumerary teeth, both primary and permanent. It alerts for potential crowding. Pediatric charts use distinct symbols for anomalies. Reference
What does a Periotest value greater than +9 indicate?
Normal healthy ligament
Increased mobility or implant failure risk
High bone density
No periodontal ligament present
Periotest values between +9 and +50 indicate high mobility or poor implant stability. Normal teeth and stable implants range between -8 and +9. This measurement aids prognosis.
Which chart symbol records palatal tori in the maxilla?

A cloud-like outline on the palatal area depicts torus palatinus. It distinguishes exostoses from normal anatomy. This is important for appliance fabrication. Reference
How is concrescence of adjacent teeth indicated in dental charting?
Two roots circled together
Red line between roots
Blue shading of crowns
Dashed cross-hatch at CEJ
Concrescence is shown by encircling the roots of adjacent teeth to indicate union by cementum. It alerts clinicians to extraction complexity. Accurate symbol prevents surgical surprises. Reference
Which notation is used to document grafting of an extraction socket with autogenous bone?

Cheat Sheet

  1. Understanding Tooth Numbering Systems -

    Master the Universal, Palmer, and FDI tooth numbering methods to ace your dental charting practice. For example, the Universal system labels the upper right third molar as #1 and the lower left third molar as #17. A simple mnemonic for FDI quadrants is "1-upper right, 2-upper left, 3-lower left, 4-lower right."

  2. Charting Restorations and Pathology -

    Learn the standard symbols for amalgam (solid black) and composite (outlined) restorations in your practice dental charting. Use a red "X" for extracted teeth and blue shading for active caries to maintain consistency. Consistent symbol use is critical for safety and clarity, as recommended by the American Dental Association.

  3. Recording Periodontal Measurements -

    Accurately chart probing depths, recession, and clinical attachment levels during dental assistant charting sessions. Use a color-coded periodontal probe (e.g., Michigan O) to quickly distinguish 1 - 3mm in black, 4 - 5mm in red, and ≥6mm in blue. The "PSR" (Periodontal Screening Record) code simplifies assessments: 0 (healthy) to 4 (severe).

  4. Key Dental Abbreviations and Terminology -

    Familiarize yourself with HOSA dental terminology practice test - style acronyms like CEJ (Cementoenamel Junction), PDL (Periodontal Ligament), and FMX (Full Mouth X-rays). Create flashcards pairing terms with definitions to streamline memorization. Official ADA and FDI glossaries are top-tier resources for accurate definitions.

  5. Legal and Ethical Documentation -

    Adopt the "If it's not charted, it's not done" mantra to ensure legally sound records during dental charting practice. Always date, time, and initial entries, and avoid ambiguous shorthand. The Dental Board of California's guidelines recommend consistent, legible notes to protect patient care and legal compliance.
