Brief Summary
The purpose of this trial is to determine the correlations between various tissue dimensions and the changes that occur following a single-tooth dental extraction in human adults. 65 adult subjects who are in need of dental extractions will be recruited. Clinical measurements will be gathered prior to and immediately following the single tooth extraction. There will be a 2-week post-operative visit to assess healing and a 14-week follow-up for photographic documentation and clinical measurements of the extraction area.

Outcome Measures
Primary Outcomes (1)
Percentage change in tissue volume - Rank Correlations
For the purpose of this study, a 10-20% reduction in the volume must detectable. Pearson correlations will be used to assess associations if appropriate and Spearman rank correlations will be considered if needed.

OTHERconsent, screening, xrays, PVS impressions, photographs, CBCT, anesthesia, extraction, clinical measurements
Interventions
At the initial screening examination, each subject will receive an informed consent form. Prior to signing the informed consent, one of the investigators or qualified staff will thoroughly discuss participation in the study with each subject, allocating time for questions and answers.
At the initial screening examination, complete medical and dental history will be obtained to verify eligibility.
each subject will undergo site-specific oral radiographic exam (new periapical radiographs will be obtained if needed) to evaluate potential study sites.
PVS impressions of the arch of interest will be obtained in order perform volumetric analysis of the area of interest.
Intraoral photographs will also be taken and subsequent study visits will be planned.
The patient will then be sent to the Department of Radiology at the College of Dentistry for a baseline CBCT and follow-up at 14 week CBCT. These CBCT's will be utilized to evaluate the hard tissue volume in comparison to the clinical volume of soft tissue.
After appropriate local anesthetic is administered and anesthesia is achieved, the buccal tissue thickness will be measured and recorded.
After the pre-extraction baseline measurements are recorded and adequate anesthesia is confirmed, minimally invasive extraction procedures will be initiated. All extractions will be performed by residents in the UI CoD Periodontics advanced education program.
Measuring soft tissue dimensions, bone thickness prior to and immediately after extraction and then after appropriate healing time frames.
Eligibility Criteria
You may qualify if:
- Age: 18 to 75 years
- Gender: No restriction
- Subjects must require a single-rooted tooth extraction (Tooth deemed as periodontally and/or restoratively hopeless) in the maxillary anterior region (first premolar to first premolar)
- Subjects must be able and willing to follow instructions related to the study procedures
- Subjects must have read, understood and signed an informed consent form
You may not qualify if:
- Reported allergy or hypersensitivity to any of the products to be used in the study
- Severe hematologic disorders, such as hemophilia or leukemia
- Active severe infectious diseases that may compromise normal healing
- Liver or kidney dysfunction/failure
- Currently under cancer treatment or within 18 months from completion of radio- or chemotherapy
- Subjects who have a long-term history of oral bisphosphonate use (i.e. 10 years or more)
- Subjects with a history of IV bisphosphonates
- Subjects with uncontrolled diabetes, defined as Hba1c \> 7.0
- Subjects with severe metabolic bone diseases, such as Paget's disease of bone, will be excluded
- Pregnant women or nursing mothers
- Heavy smokers: Subjects who have smoked \>10 cigarettes per day within 6 months of study onset
- Concomitant medications: Subjects on concomitant drug therapy for systemic conditions that may affect the outcomes of the study will not be included in the study.
- NOTE: Occasional, short-term use (7-14 days) of analgesics or common cold medications is permitted. Use of such medications will be reviewed and recorded by the investigator.
- \- Any other non-specified reason that from the point of views of the investigators will make a candidate not a suitable subject for the study (e.g. limited mouth opening).
