CAL decreased from 5.24 1.43 mm to 1.26 0.46 mm, and mean width of KT increased from 1.31 1.06 mm to 3.26 0.78 mm (Table 3). For pa- tients with maxillary MRTDs, mean RD decreased from 3.89 1.07 mm to 0.07 0.18 mm, PD de- creased from 1.45 0.37 mm to 0.92 0.29 mm, CAL decreased from 5.35 1.21 mm to 0.99 0.70 mm, and mean width of KT increased from 2.01 1.05 mm to 4.37 0.67 mm (Table 3). For both groups, statistically significant improvements were found for all clinical measurements from baseline to 6 months ( P < 0.000) (Table 3). The average percent- age of root coverage was 94% for the mandibular sites (Table 1) and 98% for the maxillary sites (Table 2). Also, the percentage of sites with complete root coverage was 57% (eight) and 85% (12), respectively. Differences between pa- tientswithmandibularor max- illary recession defects at baseline and 6 months post- surgery are summarized in Table 4. Between groups, no statistically significant differ- ences were found in preopera- tive measurements ( P > 0.01) except for CAL, whichwas sta- tistically higher for patients with mandibular MRTDs ( P < 0.000). Also, the differences betweengroupsatthe6-month follow-up were considered statistically significant for all parameters ( P < 0.01), except for PD ( P = 0.126). Table 3.

DISCUSSION Only limited data on the treatment of multiple reces- sion-typedefectshavebeenpublished inthe dentallit- erature, and the majority of studies reported the use of connective tissue grafting by tunnel approach proce- dures. 22-24,26-28 In thisstudy,the combinationofCAF surgery with a subepithelial connective tissue graft was found to be an effective procedure to cover multiple recession- type defects. When the 6-month measurements were compared to the baseline values, a significant im- provement ( P < 0.000) was observed in all clinical pa- rameters. The mean root coverage from baseline to final 6-month postoperative results was 96%, Figure 3.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
